Other features and advantages will become more apparent from the detailed description of some embodiments according to the invention.

The description is given below with reference to the accompanying drawings, which are given by way of example only and not by way of limitation, wherein:

the 1 an apparatus for controlling according to the present invention illustrated;

the 2 a front view of the device of 1 represents;

the 3 a side view (in partial and simplified section) of the device of 1 illustrated;

the 4a to 4c show three different embodiments of the means for setting the control device on an infusion device in free and fixed state;

the 5 an alternative embodiment of the device of 1 shows; and

the 6 and 7 show the second embodiment of the control device in a sequence of assembly steps.

With reference to the accompanying figures is with 1 Overall, a device for controlling the infusion referred to, which is particularly suitable for checking the amount of substance infused into a patient.

As is known, where it is necessary, certain liquids or substances such. B. infusion of drugs, nutrients or even isotonic solutions in the circulation of a patient, usually intravenous infusion equipment or infusion devices 100 used, which usually take advantage of gravity for infusion of the substance into the patient.

Such infusion devices 100 consist in particular of a bag or container 103 with a certain liquid substance 104 which is generally hung over the patient.

On the bag is a drip chamber via an output line 102 connected, which receives a predetermined amount of liquid from the bag itself and allows using a known structure, the drop of the liquid to a collecting area, which in turn by means of a pipeline 105 connected to a needle or venipuncture system for infusion of the substance into the patient's circulation.

The device 1 for controlling the infusion according to the invention is intended to be coupled to said infusion device, in particular in correspondence of the drip chamber 102 ,

In fact, the device is 1 able to check the amount (in particular the volume) of the infused liquid per unit of time so as to be able to determine the total volume infused into the patient, for example, but without limitation, the achievement of the desired amount or the depletion of the contents of the Infusion is displayed.

To perform such an operation, the device is 1 equipped with means of controlling the infused substance, in particular by a suitable sensor 4 be represented, for. As an infrared emitting diode and a receiving photodiode, which are capable of the number of votes by the infusion device and through the drip chamber 102 to check and determine passing drops.

For example, it is possible to have a transmitter 13 to be able to send out a signal to the drip area as well as one or more receivers 14 which are capable of receiving such a signal after passing through said drip area.

A control unit 15 is capable of that of the recipient (s) 14 To process incoming signal to determine the number of drops that have crossed the monitored part of the line, and thus to calculate the volume of liquid discharged from the infusion device.

This process may be carried out with the aid of statistical calculations or approximations which depend on the drip chamber used and on the estimated dimensions of each drop (eg 1 ml = 20 gtt, or 1 ml = 60 gtt for the micro drip chambers).

In a preferred embodiment, this passes through the transmitter 13 emitted signal the drip area and is then passed through a suitable reflective surface 12 such as For example, a mirror (eg, concave) is reflected to again traverse the drip area and thereby to the signal receivers 14 generally located in an area near the transmission area (see 3 ).

In detail, the infrared transmitting diode sends a beam in the direction perpendicular to the vertical falling line of the drops: the interruption of the path of such a jet indicates the falling of a drop of the solution.

As mentioned, the beam is reflected by a reflecting surface which is disposed on the opposite side in a position perpendicular to the transmitted beam in a region which is preferably protected from direct light infiltrations coming from the external environment.

The mirror may be configured to ensure that all emitted and reflected beams are directed to a single area where the receiving photodiode is located. Such a design entails the fact that the jet traverses the drip area twice and can also be intercepted in a case of imperfect vertical orientation of the drip chamber. In one embodiment, not shown, it could be the transmitter 13 itself (of a type other than a diode) receiving the reflected signal, thereby reducing the electronic components necessary for the functioning of the device.

Note further that the control device will also be adjustable, whereby in particular one can enter the total volume or the total amount of the substance to be infused. Once such an amount is reached, the device can optical and / or acoustic signaling means 17 to indicate the achievement of the desired level of infused substance or the depletion of the infusion fluid, thus attracting the attention of the professional (or patient) who can interrupt the infusion and / or replace the bag.

Consider, in particular, the benefits that such signaling can bring in the case of home treatments where the patient or his family members must control the infusion.

Note also that it will also be possible to optionally set maximum and minimum values of infusion volume per unit time (dropping rate) so as to ensure that the amount of infused substance is not greater or less than a certain limit per unit time.

For this purpose, the device with the necessary data input means 18 provided as an example of buttons, but which may be present alternatively or in combination with other means.

In fact, the set values of the device can be entered via barcodes or wireless transmission systems with proximity cards, etc.

In addition, it may be possible to protect the setting of these values so that it can only be performed by authorized personnel and not altered by unauthorized third parties.

Understandably, for reasons of ease of operation, the control device will generally not be provided with a substance release blocking mechanism and will be limited to providing an optical and / or audible signal to cause human intervention in preset signaling situations ( Exhaustion of the infusion, too high or too low rate of infusion, reaching the desired infusion rate or maximum infusion times, etc.).

In this way, no space consuming and expensive components are more necessary, such. As moving devices and actuators, and no space consuming batteries, which are suitable for the power supply last.

In this way, the operating life of the device is significantly increased, thereby reducing their space and weight and costs.

As can be seen from the figures, the device can optionally with a display 16 (for example, on the front surface, first embodiment) in order to be able to display relevant information during setting and operation (such as the falling speed of the drops, the infusion rate, the state of charge of the batteries, error signals, etc.).

In addition, at least one signal LED is provided, which flashes green in synchronization with the drop (drip display) and which is able to switch to yellow or red every time the drop falls by a time outside of predetermined minimum and maximum Maximum ranges.

In addition, an audible alarm (eg buzzer) will also be available which will be activated when the set drop rate of the drops undergoes a change that is greater than a threshold (such as 10%) up or down. The signaling can be turned off or limited to a soft signal (just a "beep" every xth second), unless the change lasts for a certain period of time (for example, three minutes). In this case, the signaling will be sustained (sustained beeping); the persistent alert may also be issued if the change exceeds another, higher than the previous, higher threshold (eg, 20%).

The power supply will be battery powered, especially rechargeable batteries, and it will be possible to achieve autonomies up to 72 hours and more, depending on the type of battery used.

In any case, the features described above can be modified without departing from the inventive concept, such. B. by what already in the European patent EP 0 718 001 has been described, which is incorporated herein by reference.

In view of the above, both illustrated embodiments have a support structure 2 on, the means 3 for fixing the device to an infusion device.

These funds 3 are particularly suitable to ensure during engagement that said sensor 4 correctly near the drip chamber 103 is positioned to correctly determine at least one characteristic parameter of an infusion rate of the infusion device 100 to allow.

In other words, the sensor 4 with the support structure 2 connected and acts on the intervention of the device with the infusion device 100 on this one.

The first embodiment of 1 to 4 sees the use of funds 3 for fixing the infusion device 1 which has at least one main engagement body 5 have, with an insertion point 6 is equipped to pass in part 101 of the infusion device 100 , such as As a tube to record when engaging the device with the infusion device.

The insertion site 6 has at least one working area at the end 7 in which the part 101 held in a stable manner to the infusion device simultaneously to the sensor 4 to allow to act on the infusion device.

As can be seen, the main engaging body is 5 essentially plate-shaped and emerges horizontally from the support structure 2 showing the major components of the device.

The insertion site 6 is from a passage point (with a passage cross section, which is substantially constant and equal to the part 101 is, which must pass through) and thereby extends through the plate passing from one of its sides to the work area 7 , which is centered in the plate itself.

The fact that the insertion site 6 has a transverse dimension substantially with the footprint of the passing part 101 of the infusion device allows to easily perform the infusion tube while hanging the device.

In the embodiments of the 4a and 4c owns the workspace 7 a cross-sectional broadening 8th with regard to the transverse dimensions of the insertion site 6 ,

This broadening is in particular of the holding structure 2 turned away, so that their weight, which is generally higher than the rest of the structure, causes a relative rotation downwards, so as to make the tube 101 in the mentioned broadening 8th introduce (and keep stable).

In other words, the holding structure occurs 2 when engaged transversely and downwardly with respect to the main engaging body 5 and the weight of the support structure 2 works with the shape of the workspace 7 together to provide a stable and accurate suspension in the relative position of the device to the infusion device.

How then in the 4b and 4c is shown, the main engaging body 5 also preferred elastic retaining means 9 exhibit to the part 101 of the infusion device in accordance with the work area 7 to keep; In particular, the elastic holding means comprise 9 a tongue 10 which is elastically deformable and is suitable for the part 101 of the infusion device stable in the work area 7 to hold as soon as the part 101 has reached this.

In detail is the tongue 10 arched with a free section 10a that's the workspace 7 is turned. Such a design allows easier insertion and removal of the mandrel. In fact, the curved sections that make up the arch constitute rest surfaces, but also attack surfaces on which the pressure required for hanging / unhooking is exerted.

Note further that the funds 3 for fixing the device 1 In addition, another engagement body 11 include, which is preferably also plate-shaped, and which is transverse to the main engagement body 5 extends (in use of the device in the vertical direction), on the opposite side to the support structure 2 concerning the main engaging body 5 , The further engagement body 11 in particular, has said at least one reflective surface 12 during the intervention of the device with the infusion device with respect to the sensor 4 on the opposite side of the dripping device 102 of the infusion device is arranged.

The invention is also an infusion unit, the at least one container 103 or pouch with a first liquid 104 for infusion, which also includes one at an exit 103a the container connected to the dripping device 102 and with at least one hose 105 equipped to carry the liquid to be infused to the patient.

The device also includes a device for controlling the infusion 1 according to what has been described above.

One also notice, like a lower surface 5a of the main intervention body 5 is intended, when using the control device on an upper wall 102 the drip chamber 102 to rest.

In this way, the control device can not shift down and can Thanks to the workspace 7 and the holding means 9 also do not move across.

The second embodiment of the following 5 to 7 is characterized in that it has a support structure 2 includes, which is a transit point 19 which is suitable, the drip chamber 102 of the infusion device 100 durchtretend record.

In this case, an unillustrated sensor 4 in accordance with the point of transit 19 arranged to engage the device with the infusion device 100 on the drip chamber 102 act.

As was made clear, the holding structure 2 thus configured "C" -shaped and the intervention of the device with the infusion device 100 is a drip chamber 102 of the infusion device 100 arranged inside the "C".

The means of fixing 3 on the other hand comprise a suspension element 20 , which is suitable when the device with the infusion device 100 slipping out of the drip chamber from the passage point 19 to prevent.

In detail is the suspension element 20 at the support structure 2 hinged and has a final hook 21 which is suitable to a part 101 of the infusion device during the intervention of the device with the infusion device 100 to brace.

As can be seen, the suspension element comprises two arms, each on the support structure 2 are hinged and the intervention of the device with the infusion device 100 stand out from this.

In particular, each of the arms has an end portion 23 transverse to the hinged to the structure initial section 22 (bent so that it forms a right angle); the end sections are connected together at one of their ends, thus the end hook 21 to build.

• – Vorbereiten einer Vorrichtung 1 gemäß der oben beschriebenen zweiten Ausführungsform;
• – Positionieren des Aufhängungselements 20 in einer ersten Position relativ zur Haltestruktur 2 (6, in welcher das Element 20 auf die Haltestruktur gefaltet ist), in welcher ein Eingriff eines Teils 101 des Infusionsgeräts mit dem Aufhängungselement 20 und insbesondere mit dem Endhaken 21 erlaubt ist;
• – Festlegen des Teils 101 des Infusionsgeräts 100 am Haken 21;
• – Drehen der Haltestruktur 2 in Bezug auf das Infusionsgerät 100, bevorzugt um ungefähr 90°, damit ein Teil einer Tropfkammer 102 des Infusionsgeräts 100 in den Längssitz 19 der Haltestruktur 2 eingesetzt wird.

Assuming the structure, the method of assembling the infusion control apparatus according to a second embodiment comprises the following steps:

• - Prepare a device 1 according to the second embodiment described above;
• - Positioning the suspension element 20 in a first position relative to the support structure 2 ( 6 in which the element 20 folded on the support structure) in which an engagement of a part 101 of the infusion device with the suspension element 20 and in particular with the end hook 21 allowed is;
• - Specify the part 101 of the infusion device 100 on the hook 21 ;
• - Turning the holding structure 2 in relation to the infusion device 100 , preferably at about 90 °, to allow part of a drip chamber 102 of the infusion device 100 in the longitudinal seat 19 the holding structure 2 is used.

By proceeding in this manner, one obtains a stable fixation of the device on the infusion device, since the hook slips between the drip chamber 102 and the support structure 2 along the passage 19 prevented. The latter prevents all other movements in the plane, and the resting of the hook on the upper surface of the dripping device 102 determined the correct positioning in relation to the vertical.

In addition, a position sensor can be provided, which automatically turns on the device once it has been placed on the drip chamber and is in the correct (horizontal) position.

The invention brings with it important advantages. First and foremost, the realized fixing means have a simple execution and implementation; they require no special measures, but allow a reliable and fixed relative positioning of the intravenous infusion system to the control device.

The special geometry of the working area improves the engagement and the mutual fixing, without affecting the manufacturing costs and the simplicity of implementation.

The device therefore has very small dimensions and lighter weight, although it guarantees maximum functional autonomy and reliability.

The device can be used both in the hospital and in the patient's home because it does not require any expertise in use and thereby very effectively improves the control conditions of the infusion.

Finally, it should be noted that the control device (due to its stable positioning) is able to function even when the patient is moving, e.g. B. when it transports the holding structure of the drip infusion together with the bottle or bag, which is subjected to noticeable oscillations.
