Description

Sterile protection device system

The present invention relates to a sterile protection device system comprising a sterile protection device for a mobile terminal, in particular for a smartphone and a tablet computer, which protection device comprises a housing which defines a receiving space in the interior.

Sterile protection device systems of the type described above are known, for example in the form of film sleeves, in which mobile terminals, especially used in surgical procedures smartphones or tablet computers, can be introduced.

However, such sterile protective devices are cumbersome to use, especially when used in an operating room. For example, a readability of a display of the terminal may be impaired if the protective film is not flat on the display.

It is therefore an object of the present invention to improve a sterile protection device system of the type described above so that it is easier for an operator to use mobile devices, in particular smartphones or tablet computers, in a surgical procedure.

This object is achieved in a sterile protection device system of the type described above according to the invention that the housing comprises a lower housing part and a housing upper part for germ-tight sealing of the housing lower part in a closed position.

The inventively proposed protection device system makes it possible in particular to insert the mobile terminal, for example, in the lower housing part or the upper housing part and then close the lower housing part with the upper housing part or vice versa germ-tight and so in the Ste- to bring in. Thus it can be avoided that bacteria adhering to the mobile terminal can enter the operating area and lead to infections. In particular, when the housing, for example, the lower housing part and the upper housing part, consist of sufficiently stable and stiff materials or parts, so a defined positioning of the mobile terminal in the sterile protection device can be achieved. This improves in particular the readability of a display of the mobile terminal. The stiffer and more stable the housing, the easier it is also manageable, in the desired manner offable and possibly also attachable, for example on a tripod of an operating table or the like.

It is advantageous if the protective device system comprises a sealing device for germ-tight sealing of the housing in the closed position. With the sealing device, it is in particular possible to seal the lower housing part and the upper housing part germ-tight relative to each other.

The protective device system can be designed in a particularly cost-effective manner if the sealing device comprises at least one sealing element which, in the closed position, bears against both the upper housing part and the lower housing part. This makes it possible, in particular, to seal the upper housing part and the lower housing part directly relative to each other.

The handling of the protection device system can be further simplified in particular by the fact that the at least one sealing element is arranged or formed on the upper housing part or on the lower housing part. It then does not have to be separately positioned by an operator, but the housing top and housing bottom can be directly engaged with each other to close the receiving space.

In order to allow a user of the protection device system in a simple manner to view a display of the mobile terminal positioned in the protection device in the reception space, it is favorable if the housing upper part comprises a viewing window. The position of the viewing window can be specially adapted to the male mobile terminal, so that it is ensured that the display of the terminal is optimally visible.

A user can look at the display or a display device of the mobile terminal particularly well if the viewing window is transparent and arranged above the receiving space.

The sterile protection device system can be produced particularly simply and inexpensively if the viewing window is made of a transparent plastic or of glass. In particular, the transparent plastic may be a hard plastic or Plexiglas, for example. The glass can also be designed in the form of a shatterproof glass.

According to a further preferred embodiment of the invention it can be provided that the receiving space comprises at least one heat sink receptacle for receiving a heat sink coupled to the mobile terminal. The provision of at least one heat sink receptacle makes it possible to dissipate heat from the mobile terminal, which arises during its operation, from the terminal at least partially. This can be achieved, for example, by coupling the mobile terminal with one or more heat sinks. To ensure optimum thermal contact between the heat sink and the terminal, the sterile protection device surrounds not only the terminal but also the heat sink coupled to the terminal. Although this leaves at least a portion of the heat generated by the mobile terminal in the receiving space or in the at least one heat sink, but is at least partially removed by the mobile terminal to prevent overheating of the mobile terminal. In addition, the heat can still further derived from the heat sink, if the housing itself is at least partially formed of a thermally conductive material, such as a metal. In particular, for example, the heat sink can be brought directly into contact with the housing in order to dissipate generated heat from the receiving space through the housing. The sterile protection device can be formed in a simple manner if the at least one heat sink receptacle is designed in the form of a depression of the receiving space. A shape of the recess can be chosen arbitrarily. Preferably, it is adapted to a shape of the coupled to the mobile terminal heat sink to accommodate this completely.

It is advantageous if the at least one heat sink receptacle is arranged or formed on the lower housing part. In this way, for example, a heat sink can be coupled to a rear side of the mobile terminal and used together with the mobile terminal in the lower housing part.

It is advantageous if the upper housing part has a housing upper edge surrounding the housing lower part and if the upper housing edge at least partially overlaps the lower housing part in the closed position. In this way, the receiving space can be closed very safe and germ-proof. A function of a sealing device can thus be additionally improved. The upper housing edge preferably completely overlaps the lower housing part, in particular a lower housing edge of the lower housing part pointing in the direction of the upper housing part. This ensures, in particular, that no unsterile areas, for example the lower housing edge, when it touches non-sterile material during the insertion of the mobile terminal into the receiving space and is thus contaminated with germs, remain uncovered after the mobile terminal has been inserted into the receiving space and with it the upper housing part is closed.

Preferably, the sterile protection device system comprises a connecting device for non-positive and / or positive connection of the lower housing part and the upper housing part in the closed position. The connecting device makes it possible, in particular, to connect the lower housing part and the upper housing part in a defined manner, so that a risk is minimized that the space in the receiving space is minimized. Mene mobile terminal from the housing in an undesired and unintentional manner leak and can burden the sterile surgical area with germs.

In a particularly simple manner, the upper housing part and the lower housing part can be connected to one another in the closed position if the connecting device comprises at least one connecting projection and at least one corresponding connection receptacle, which are arranged or formed on the upper part of the housing and on the lower part of the housing and force and / or in the closed position. or positively engage with each other.

The handling of the sterile protection device system can be improved in particular by the fact that the housing upper part comprises the at least one connection receptacle and the housing lower part comprises the at least one connection projection. Thus, for example, the upper housing part can be guided over the lower housing part, so that the at least one connecting projection can engage in the at least one connection receptacle on the upper housing part.

The sterile protection device system can be made particularly compact if the at least connection receptacle on the housing upper edge is designed in the form of a peripheral, inwardly directed groove and if the housing lower part comprises the at least one connecting projection. This configuration makes it possible in particular to arrange the connection receptacle well protected on the housing or form.

Forming in a simple and compact way, the sterile protection device system, if the at least one connecting projection is formed in the form of a circumferential housing lower edge. For example, the lower housing edge may be profiled in order to additionally increase stability of the housing. In order to realize the connection between the lower housing part and the upper housing part easier and more secure, it is advantageous if the at least one connection receptacle is bounded on one side by a latching element. The provision of a latching element in particular allows an embodiment of the connecting device such that the at least one connecting projection snaps into the connection receptacle when it is inserted in order to be transferred into the closed position.

Preferably, the locking element is designed in the form of a circumferential, bead-shaped or substantially bead-shaped latching projection. For example, a risk of injury to an operator can be minimized. In the choice of suitable materials so also the at least one connecting projection can easily and safely snap into the connection receptacle to connect the lower housing part and the upper housing part with each other.

In order to further improve the tightness of the sterile protective device, it is favorable if the latching element partially engages or engages behind the lower housing edge in the closed position.

It is advantageous if the protective device is made of at least one sterilizable and / or dimensionally stable material. This makes it possible in particular to sterilize the protection device before and / or after insertion of the mobile terminal in the receiving space if necessary. The use of a dimensionally stable material also has the advantage that the protective device already without the mobile terminal used has a certain stability and thus in particular the risk of damage to the protective device is minimized.

In a simple way, the sterile protection device can be sterilized if the at least sterilizable and / or dimensionally stable material can be sterilized with superheated steam or with gamma radiation or with ethylene oxide (ETO). In a simple manner, the sterile protection device can be formed if the at least one sterilizable and / or dimensionally stable material is a sterilisable plastic or a sterilizable metal or glass. For example, the sterilizable plastic polyetheretherketone (PEEK), polycarbonate (PC), polystyrene (PS), a polyolefin, in particular polyethylene (PE) or ultra-high molecular weight polyethylene (UHMWPE), a polyester, in particular polyethylene terephthalate (PET) or polyethylene terephthalate with glycol ( PETG), a polyacrylate and / or a polymethacrylate, in particular polymethyl methacrylate (PMMA). In particular, stainless steel, chromium-nickel steels, titanium, titanium alloys and / or aluminum can be used as the sterilizable metals.

The provision of sterilizable protective devices can be particularly space-saving, if the lower housing part and the upper housing part are formed separately from each other and are completely separated from each other in an insertion position. In addition, the introduction of a mobile terminal in the receiving space can be simplified as well.

In a further preferred embodiment of the invention can be provided that the lower housing part and the upper housing part are hinged together and from the closed position into an insertion, in which the receiving space is open, can be transferred. This embodiment makes it possible in particular to open the housing in a simple manner, to insert the mobile terminal in the receiving space and to close the housing again.

The sterile protective device can be designed in a particularly simple and cost-effective manner if it comprises a joint for pivoting the lower housing part and the upper housing part relative to one another about a pivot axis. Thus, for example, an operator can hold the lower housing part and, in order to open the housing, pivot the upper housing part about the pivot axis defined by the joint. Depending on the configuration of the lower housing part and the upper housing part, it is advantageous if the joint is designed in the form of a hinge joint or a solid-body joint. For example, in a one-piece design of the protective device, it is cost-effective to provide a solid-state joint, which integrally connects the lower housing part and the upper housing part with each other. The formation of more complex joints, for example, with a pivot pin defining the pivot axis, which passes through corresponding bearing elements on the housing base and the housing top, can be particularly useful and advantageous if the housing base and the housing top are reusable, this after removal of the mobile terminal after a to clean and re-sterilize surgery.

In order to facilitate the insertion of the mobile terminal into the sterile protection device and to avoid contamination of the protection device when inserting the mobile terminal into the receiving space, it is advantageous if the sterile protection device system comprises a sterile funnel for sterile insertion of the mobile terminal into the receiving space. For example, the sterile funnel in the form of a Einführrahmens be formed with a circumferential side wall which is sterilized even before use and which limits the non-sterile part of the protection device on an inner side, with an outside of the mandatory sterile part of the protection device.

In order to be able to discharge heat generated by the mobile device simply and safely, it is advantageous if the sterile protection device system comprises at least one heat sink which is arranged or formed in the receiving space. In addition, the heat sink is either permanently coupled to the mobile terminal or releasably connectable with this.

It is advantageous if the sterile protective device system comprises at least one fastening element for direct or indirect fixing of the protective device to an operating table. The at least one fastening In particular, the user makes it possible for a user to set the protective device with the mobile terminal inserted therein in the desired manner in an operating room, for example on an operating table.

In a particularly simple manner, the sterile protection device can be handled if the at least one fastening element is designed in the form of a fastening clip which can be frictionally and / or positively engaged with the at least one heat sink receptacle and with a stand element of a fastening system that can be fastened to an operating table is. Coupling or connecting the fastening clip to the heat sink receiving preferably takes place in such a way that the fastening clip completely or partially surrounds a protuberance or convexity of the housing formed by the at least one heat sink receptacle or also engages in the same from the outside.

It is advantageous if the at least one fastening element comprises at least one magnet for magnetic coupling with the protective device or a mobile terminal received in the protective device in the closed position. With a magnet, the protective device or the mobile terminal used in this can be easily with example, a tripod element, which can be arranged on an operating table, couple.

In order to avoid that inappropriate mobile terminals are used in the protection device, it is advantageous if the receiving space is adapted to an outer contour of the mobile terminal for the positive or substantially positive recording of the same in the closed position.

The sterile protection device system is in particular immediately ready for use if it comprises a mobile terminal. This can for example already be introduced into the sterile protection device before it is brought into the sterile environment of an operating room. The following description of a preferred embodiment of the invention serves in conjunction with the drawings for further explanation. Show it :

In FIGS. 1 to 3, a first exemplary embodiment of a sterile protection device system, generally designated by the reference numeral 10, is shown schematically. The protective device system 10 comprises in particular a sterile protective device 12 for a mobile terminal 14, which is shown schematically in FIG. 1 in the form of a tablet computer 16. It may alternatively be designed in the form of a smartphone.

The protective device 12 comprises a housing 18 with a housing lower part 20 and an upper housing part 22. The housing 18 defines in its interior a receiving space 24 for receiving the terminal 14th

The housing upper part 22 is designed for the germ-tight sealing of the housing lower part 20 in the closure position shown schematically in FIGS. 2 and 3.

The tablet computer 16 has a substantially cuboid terminal housing 26, with a screen 28 arranged on an upper side thereof, occupying substantially the entire upper side.

On a bottom 30 of the tablet computer 16, a cooling plate 32 is arranged flat, which comprises two cuboid heat sinks 34 and 36.

In a bottom 38 of the housing base 20, two heat sink receptacles 40 and 42 are formed in the form of cuboid protuberances of the housing base 20, which serve to receive the heat sink 34 and 36, respectively. The heat sink receptacle 40 is dimensioned such that the heat sink 34 dips positively into the heat sink receptacle 40 and fills it substantially completely. The heat sink receptacle 42, however, is more than twice as large as the heat sink 36, so that in addition to this, when it engages in the heat sink receptacle 42, still a cavity 44 remains. The lower housing part 20 comprises a lower housing edge 46 which annularly surrounds an insertion opening 48 of the receiving space 24. It comprises a running parallel to the bottom 38, circumferential wall portion 50 which adjoins a side wall 52 laterally surrounding the receiving space 24, which is formed from four rectangular wall sections, and preferably perpendicular to these. At an outer edge 54 of the wall section 50 pointing away from the receiving space 24, a further outer wall 56 extending parallel to the side wall 52 is integrally formed, which comprises four rectangular wall sections.

The upper housing part 22 comprises a cover wall 58, which runs parallel to the floor 38. The top wall 58 comprises a viewing window 60, which is set back relative to the top wall 58 somewhat in the direction of the bottom 38. The viewing window 60 is preferably transparent and located directly above the receiving space 24, such that the screen 28 is completely visible through the viewing window 60.

Perpendicular to the top wall 58, these four rectangular wall sections, which define a circumferential housing top edge 62, the height 64 is perpendicular to the bottom 38 is slightly greater than a height 66 of the outer wall 56th

On an inner side 68 of the upper housing edge 62, a bead-shaped latching projection 70 projecting in the direction of the side wall 52 is formed. Between the locking projection 70 and the top wall 58, a connecting receptacle 72 is formed, in which engages a defined by the outer wall 56 connecting projection 74 in the closed position. The latching projection 70 forms a latching element 76, which limits the connection receptacle 72 on one side. The connection receptacle 72 is thus formed by a circumferential groove 78 directed inwards towards the receiving space 24. The connecting receptacle 72 and the connecting projection 74 form parts of a connecting device 80 for non-positive and / or positive connection of the lower housing part 20 and the upper housing part 22 in the closed position.

The lower housing part 20 and the upper housing part 22 of the protective device 12 are formed completely separated from each other. In an insertion position, as shown schematically in Figure 1, the cooling plate 32 can be used with the heat sinks 34 and 36 and the mobile terminal 14 first in the housing base 20 in the manner described. Thereafter, the upper housing part 22 is pushed from above over the lower housing part 20 until the outer wall 56 engages in the groove 78. The upper housing edge 62 thus overlaps the lower housing edge 46 at least partially.

In the closure position shown schematically in Figure 3, the wall portion 50 engages in a shallow recess 82 on the housing top 20, which is bounded by the upper housing edge 62, the top wall 58 and the recessed relative to the top wall 58 viewing window 60. The housing upper edge 62 not only overlaps the wall portion 50, but also the outer wall 56 completely. This ensures, in particular, that no unsterile areas, for example the wall section 50 and the outer wall 56, when touched when the mobile terminal 14 is inserted into the receiving space 24 with non-sterile material and thereby contaminated with germs, remain uncovered after the mobile terminal 14 inserted into the receiving space 24 and this is closed with the upper housing part 20.

FIG. 4 schematically shows a modification of the protection device system 10 '. The protective device 12 'in this case comprises a housing lower part 20' and an upper housing part 22 ', which are formed substantially identical to the lower housing part 20 and the upper housing part 22. However, the lower housing part 20 'and the upper housing part 22' are pivotally connected to each other, via the joint 84. This is in the form of a hinge joint 86, which the housing lower part 20 'and the Housing upper part 22 'via a hinge pin 88 pivotally coupled to a pivot axis defined by this 90.

To insert the terminal 14 of the upper housing part 22 'to the

Swivel axis 90 of the housing base 20 'pivoted away. After insertion of the terminal 14, the upper housing part 22 'can be pivoted back onto the lower housing part 20'.

For sealing the lower housing part 20 and the upper housing part 22 relative to one another in the closed position, optionally a sealing device 92 may be provided, which comprises a circumferential sealing element 94. This can either be arranged or formed on the lower housing part 20 or on the upper housing part 22. Such a sealing element 94 is shown by dotted lines in FIG. 3, for example, in the transition region between the viewing window 60 and the side wall 52.

In an analogous manner, a sealing element can also be arranged or formed on the housing lower part 20 'or on the housing upper part 22' in the protective device 12 '.

The sealing device 92 may also be arranged or formed at any other point of the housing 18, and wherever it may simultaneously be in contact with the housing lower part 20 and with the housing upper part 22.

In the figures 5 to 8 again the protection device system 10 is shown schematically. This is in addition to the parts shown in Figure 1, a so-called sterile funnel 96. It is formed by a rectangular frame 98 with a circumferential, four wall sections comprising funnel wall 100, wherein the wall sections upon proper use of the sterile funnel 10 during insertion of the cooling plate 32 and the Heat sinks 34 and 36 are aligned parallel to the wall portions of the side wall 52. The lower housing part 20, the upper housing part 22 and the sterile funnel 96 are preferably packed together in a sterile bag 102. To prepare for use in the operating room, the so-called unsterile sister opens the bag 102, so that the so-called sterile sister can remove the lower housing part 20, the upper housing part 22 and the sterile funnel 96 and place it on a sterile covered supply table. In this case, it lies on the housing base 20 on the supply table so that the receiving space 24 is freely accessible. The upper housing part 22 is deposited so that the inner side of the viewing window 60 pointing in the closed position towards the receiving space 24 points upwards.

Subsequently, the sterile sister places the sterile funnel 96 on the housing lower part 20 such that the sterile funnel surrounds the receiving space 24.

Optionally, the sterile funnel 96 can also be integrated into the housing lower part 20.

Now the unsterile sister can first insert the cooling plate 32 with the heat sinks 34 and 36 through the sterile funnel 96 into the receiving space 24. Thereafter, the mobile terminal 14 can be inserted into the receiving space 24.

Subsequently, the unsterile sister removes the sterile funnel 96.

Finally, the sterile sister closes the housing 18 by guiding the housing top 22 over the housing bottom 20 and locking the two parts together.

Optionally, the insertion of the terminal 14 in the receiving space 24 can also be done without sterile funnel 96, since the sterility of the protective device by the enclosing and the housing base 20 completely overlapping housing upper part 22 should already be guaranteed.

In order to improve the operability of the terminal 14, which is located in the receiving space 24, with surgical gloves, in particular the entire upper housing part 22, but at least the viewing window 60 can be made of a conductive plastic.

Furthermore, the housing upper part 22 may optionally be provided with an adhesive layer on the inside or in the entire area, for example in the form of known screen protectors, so as to temporarily achieve a firm connection between the viewing window 60 and in particular in the form of a touch-sensitive screen 28, also referred to as a touch screen ,

Further, the viewing window 60 may optionally be provided with an anti-reflection layer.

The housing base 20 is preferably formed of a material of a material with good thermal conductivity, for example a metal, in particular aluminum.

Further, in the region of the receiving space 24 on the lower housing part 20 locking lugs may be formed in order to fix the mobile terminal 14 already in the lower housing part 20, in particular to relieve the upper housing part 22 in the closed position.

Furthermore, integrated membrane layers or thinner regions can optionally be formed in the upper housing part 22 and / or in the lower housing part 20 to allow an improved reproduction function and microphone use of the mobile terminal 14, in particular to permit voice control of the mobile terminal 14. Furthermore, inserts, for example reducing frames, not shown in the drawings can optionally also be provided in order to use different mobile terminals 14, for example tablet computers with screens 28 of different sizes. This also makes it possible, in particular, to use the protective device 12 for receiving mobile terminals 14 in the form of smartphones.

Furthermore, an interface for the inductive power supply in the sterile area can optionally also be formed on the housing 18, for example in the bulges 40 or 42 forming bulges of the housing base 20. These bulges also serve as feet of the housing 18, so that the terminal 14 is based on a standing surface is inclined aligned, in particular by the fact that a height of the heat sink receiving 42 surrounding side wall 104 perpendicular to the bottom 38 is less than half as large as a height of the heat sink receiving 40 surrounding side wall 106th

The provision of the sealing device 92 in particular allows washing the protective device 12 under running water in order to remove soiling occurring on the viewing window 60 during a surgical procedure.

If the lower housing part 22 is sufficiently stable, the upper housing part 22 may also be designed in the form of a latex cover, for example in the form of a sterile rubber cover. Such a design makes, in particular, a sealing device virtually obsolete.

In order to easily remove the mobile terminal 14 after use, 20 predetermined breaking points can be provided by material weakenings or tabs, in particular on the upper housing part, which simplify removal of the upper housing part 22 from the lower housing part 20. Furthermore, movable or elastic regions can optionally also be provided on the housing 18, in order to be able to operate, in particular, important mechanical keys of the mobile terminal 14 even when it is arranged in the receiving space 24. In particular, these keys may be on / off or volume control keys.

If the mobile terminal 14 comprises a camera, the protection device 12 is in particular designed such that the camera is fully functional through the viewing window 60. This allows in particular an operation of the mobile terminal 14 via gesture control.

Furthermore, an integrated fan for convection cooling can optionally also be arranged or formed in the receiving space 24 or in the heat sink seat 40 or in the heat sink seat 42. This can for example be coupled via an interface with the mobile terminal 14 and operated by this.

In order to further improve the dissipation of heat generated by the mobile terminal 14 in the housing 18, optionally the housing lower part 20 or the housing upper part 22 can be wholly or partly formed from a heat conducting foil.

In order to position and secure the mobile terminal 14 in the protector 12 in an operating room in an optimal manner for a surgeon, the protector system 10 may further include at least one fastener 108. This may be formed, for example in the form of a mounting bracket 110 having a first receptacle 112, with which, for example, the housing base 20 in the region of one of the two heat sink receptacles 40 or 42 can be frictionally and / or positively captured, and in addition with a further receptacle 114th is equipped to a non-positive and / or positive connection with a stand member 116, for example, a support rod 118 which is attached to an operating table 120, enter, so that the mobile terminal, such as schematically shown in Figures 9 and 10, can be positioned and fastened directly to the operating table 120.

In the described embodiments, in particular, the heat sink 34, which engages in the heat sink receptacle 40, serve as an integrated mechanical interface for connection to the mounting bracket 110 or a corresponding support arm 122 on the operating table 120. The holding arm 122 can in particular be fastened to a so-called standard rail of the operating table 120. A determination of the housing 18 in the region of the heat sink 34 then takes place in particular without damaging the sterile protective device 12.

Optionally, the provision of a magnet in the region of the heat sink receptacles 40 or 42 or at another location on the housing base 20 is conceivable or on the fastener 108 or on the support arm 122 to allow a magnetic fixation of the protective device 12 on the operating table 120.

Furthermore, an eyelet or a loop can optionally also be formed on the housing 18, for example on the upper housing part 22 or on the lower housing part 20, which make it possible to hang the protective device 12 on an infusion stand, for example. The eyelet or the loop can in particular be formed integrally with the housing lower part 20 or the housing upper part 22.

The lower housing part 20 and / or the upper housing part 22 may be formed in the form of a so-called blister. The viewing window 60 may in particular be shaped, transparent and formed with a thickness in a range of 0.05 mm to 0.2 mm, whereby wrinkling and the formation of air bubbles prevented and still a safe and comfortable operation of the mobile terminal with operations -Handschuhen is possible. The heat sink receptacles 40 and 42, like the lower housing part 20 and / or the upper housing part 22, can also be formed by deep-drawing suitable materials, such as plastics or metal foils.
