Description

D E S C R I P T I O N "Immobilization device for immobilizing a patient"

TECHNICAL FIELD

This invention relates to devices suitable for immobilizing and transporting a patient during a rescue operation.

PRIOR ART

There are known immobilization units used in rescue situations that comprise a fixed part and a detachable part. The detachable immobilization part is used, for example, to immobilize a patient inside a vehicle that has suffered a crash. In this stage the skull-cervical and thoracic-abdominal areas of the patient are immobilized. This operation is very delicate and complicated as it must be performed in a small space and without exact knowledge of the injuries suffered by the accident victim. To prevent more serious injuries it is important that the patient is kept in the correct posture and is prevented from making undesirable movements. To keep the patient immobilized the use of a plurality of straps or belts is known. Once the patient has been extricated from the vehicle, the detachable immobilization part is attached to the fixed immobilization part to immobilize the rest of the patient's body.

In this respect US7082632 B2 discloses a device for immobilizing a patient or an accident victim in a rescue situation. The device comprises three units, the first one to immobilize the skull-cervical areas, the thorax and the abdomen of the patient and the second one to immobilize the rest of the body. The third unit is optionally used as an annex for tall patients. These three units are attached to each other. The first unit is used to immobilize the patient, for example, inside a vehicle that has suffered a crash where the straps that are used to tie and to immobilize the patient on the immobilization device are flexible straps that are rested on the body of the patient. DE3546526 A1 discloses a device for carrying a patient comprising a first immobilization unit and a second immobilization unit, said first and the second immobilization units being fixed on a frame formed by longitudinal beams. Said first immobilization unit pivots related to said second immobilization unit in order to be leaned. The second immobilization unit comprises lateral supporting flaps fastened on the frame.

DISCLOSURE OF THE INVENTION

It is the object of this invention to provide a device for immobilizing a patient so that he can be transported or transferred in a safe manner, as described in the claims.

The immobilization device of the invention comprises a first immobilization unit and a second immobilization unit. The first immobilization unit comprises a first locking unit to immobilize the skull-cervical anatomical area and a second locking unit to immobilize the thoracic-abdominal area of the patient. The second immobilization unit comprises a third locking unit that immobilizes the pelvis and the patient's lower limbs. The immobilization device also comprises a plurality of fixing means which enable the patient to be kept in the immobilized position. The first immobilization unit is detachable from the second immobilization unit, said second immobilization unit being suitable for receiving and fixing said first immobilization unit. The first immobilization unit comprises a base on which the first locking unit and the second locking unit are disposed. In order to optimise the immobilization of the patient, thereby reducing the risk of causing more injuries or even aggravating the injuries already suffered, the second locking unit of the first immobilization unit comprises two rigid or semi-rigid flaps, preferably arched, fitted on each side of the base in a pivoting and/or detachable manner. Said flaps surround and immobilize (through the use of the corresponding fixing means) the thorax and the abdomen area of the patient. As a result, the patient and the first immobilization unit are moved together as one as if they were a single body. This is especially advantageous, for example, in the rescue of a patient with a multiple polytrauma, who is trapped inside a vehicle, whose extrication and transporting is vital so as not to aggravate the injuries suffered by the patient. These and other advantages and characteristics of the invention will be made evident in the light of the drawings and the detailed description thereof.

DETAILED DESCRIPTION OF THE INVENTION The immobilization device 1 of the invention, as shown in Figure 1 , comprises a first immobilization unit 2 and a second immobilization unit 3. The first immobilization unit 2 comprises a first locking unit 4 to immobilize the skull-cervical anatomical area and a second locking unit 5 to immobilize the thoracic-abdominal area of the patient. The second immobilization unit 3, shown in more detail in Figure 2, comprises a third locking unit 6 that immobilizes the pelvis and the patient^'s lower limbs. The immobilization device 1 also comprises a plurality of fixing means 7, which enable the patient to be kept in the immobilize position.

The first immobilization unit 2 is detachable from the second immobilization unit 3, said second immobilization unit 3 being suitable for receiving and fixing said first immobilization unit 2. The first immobilization unit 2 comprises a base 10, as shown in Figure 5A, on which the first locking unit 4 and the second locking unit 5 are disposed.

In order to optimise the immobilization of the patient, thereby reducing the risk of causing more injuries or even aggravating the injuries already suffered, the second locking unit 5 of the first immobilization unit 2 comprises two rigid or semi-rigid flaps 9, preferably arched, to follow the patient's outline, fitted to each side of the base 10 in a pivoting and/or detachable manner, as shown in Figures 5A and 5B. Said flaps 9 surround and immobilize (through the use of the corresponding fixing means 7) the thorax and the abdomen of the patient, as shown in Figure 6. As a result, the patient and the first immobilization unit 2 are moved together as one as if they were a single body. The fact that the first immobilization unit 2 is detachable and therefore separable from the second immobilization unit 3 and that the flaps 9 surround and immobilize the thorax and the abdomen of the patient is especially advantageous, for example, in the rescue of a patient with a multiple polytrauma, who is trapped inside a vehicle, whose extrication and transporting is vital so as not to aggravate the injuries suffered by the patient.

In a first embodiment of the invention, the base 10 of the first immobilization unit 2 comprises two parts, as shown in Figure 5B, which are joined laterally, as shown in Figure 5 A. The two parts have substantially the same width. This feature is really advantageous, especially for immobilizing the patient in areas of reduced accessibility, such as the inside of a vehicle that has suffered an accident. Each part of the first immobilization unit 2 is approached from each side of the patient, joining both parts in a simple manner behind the back of the patient and being fixed by means of a safety bolt 24. This prevents having to move the patient in order to house and fix the first immobilization unit 2 in the second immobilization unit 3. In emergency situations it is difficult to assess the internal injuries suffered by the patient, which means that the patient must be moved as little as possible so as not to aggravate the injuries and even cause new ones during the immobilization. Once the immobilization device 2 has been placed behind the patient's back, the flaps 9 are approached, each one pivoting on its axis situated on the edge of the base 10, in order to surround the patient's abdomen and/or thorax. The skull-cervical area of the patient is then immobilized, as will be detailed hereinafter, and the patient is then immobilized from the waist or pelvis upwards through the use of the fixing means 7. Thanks to the fact that the flaps 9 surround the patient, there is no relative movement between the patient and the first immobilization unit 2, so the first immobilization unit 2 and the patient are moved together as one as if they were a single body. This prevents the incorrect movement of the patient, thereby preventing, for example, injuries to the spinal column during the extrication and transporting of the patient. In the first embodiment, the flaps 9 and the base 10 of the first immobilization unit 2 are made of the same material so that the first immobilization unit 2 is more robust and the patient is more protected. In addition, during the immobilization of the abdominal and thoracic area of the patient, the patient's ribs are prevented, for example, from suffering injury during the fixing or fastening of the fixing means 7 due to an excessive force exerted directly on the patient's body. However, the flaps 9 and the base 10 may optionally be made of different material in order to find different performs of the same. In the first embodiment of the invention, the flaps 9 of the first immobilization unit 2 are pivoting and detachable. This feature is especially useful in making the rescue operation of the rescue team members easier. The flaps 9 may be detached before starting rescue operation, and once the skull-cervical area of the patient has been immobilized, the flaps 9 may be fitted once again, by the sides of the patient, in order to immobilize the abdomen and/or the thorax areas. The rescue team members thus have greater visibility and control of the situation.

In a second embodiment, where the base 10 of the first immobilization unit 2 does not comprise two parts, the solution by which the flaps 9 are detachable is very advantageous for positioning the first immobilization unit 2 correctly in relation to the patient without unnecessary obstacles, reducing their movements and offering greater visibility and control of the situation.

Thanks to the arched shape of the flaps 9, these adapt to all types of bodies, including adults, children and corpulent or thin people and so on, approaching more or less to adapt to the outline of the patient. As a result, if the patient is a strong person the flaps 9 surround the patient, with a medium-sized space being left between both flaps 9. If the patient is a thin person or a child, the flaps 9 surround the patient, with a minimal space being left between them, and if the patient is a corpulent or obese person the space between the flaps 9 is larger.

To immobilize the skull-cervical area of the patient, as shown in Figure 5A, the first locking unit 4 of the first immobilization unit 2 comprises skull fixing means 13 in the form of pads, preferably made of plastic, which are adjustable so they can adapt to the differing sizes of patients' skulls, and detachable so that they can be easily cleaned, among other functions. The first locking unit 4 also comprises cervical fixing means 14. Said means comprise a second set of adjustable and detachable pads, as shown in Figure 1 , and a cervical immobilizer 15, preferably in the form of as a surgical collar, which is connected to the second set of pads by means of connection means, preferably by Velcro. As shown in Figure 5A, the cervical immobilizer 15 of the first embodiment comprises an opening 29 to enable cricoid or airway puncture should it be necessary. If the patient has already been assisted and has had the surgical collar fitted, the first immobilization unit 2 could do without the cervical fixing means, replacing them by the means already possessed by the patient. Trough the use of the fixing means 7 the skull-cervical area of the patient is ultimately fixed to the first immobilization unit 2, as shown in Figure 6.

The first immobilization unit 2 may comprise on one side storage means for storing auxiliary elements such as monitoring cables, so that the rescue team members always have everything they need to hand. It may also comprise auxiliary guidance means, not shown in the drawings, to guide said auxiliary elements so that they do not bother the patient. They may even guide additional elements such as an oxygen cylinder, which is needed to aid a patient suffering asphyxia.

Once the patient has been immobilized from the waist or pelvis up, the first immobilization unit 2 is fitted on the second immobilization unit 3 of Figure 2, if the first immobilization unit 2 has been taken out beforehand (for example, to immobilize the patient inside the vehicle that has suffered an accident or to rescue a person in the sea). To enable this, the first immobilization unit 2, as shown in Figure 3, comprises guidance means 12, preferably in the form of grooves, which cooperate with coupling means 16, preferably in the form of rods, comprised in the second immobilization unit 3, the patient thus being lied down in a horizontal position, as shown in Figure 6, thus preventing the patient from having to be moved in order to transfer them to another transfer or transporting unit, such as a stretcher. The coupling means 16 of the second immobilization unit 3 are housed in the guidance means 12 of the first immobilization unit 2, and then the first immobilization unit 2 is moved towards the lower part of the second immobilization unit 3 until fixing protuberances 27 are housed in retaining means 28. The fixing protuberances 27 are preferably in a circular form to enable the first immobilization unit 2 to pivot and are comprised in the lower part of the base 10 of the first immobilization unit 2. The retaining means 28 are preferably in the form of a groove and are comprised in the top part of the third locking unit 6 of the second immobilization unit 3, as shown in detail in Figure 4. Finally, the first immobilization unit 2 is locked, in other words it is fixed and secured, by means of locking means 17, shown in Figures 1 and 2, comprised in the second immobilization unit 3. The locking means 17 are movable, so that said locking means 17 are moved towards the first immobilization unit 2 until retaining means 25 shown in Figure 2, preferably in the form of a groove, fix at least in one protuberance 26, preferably rectangular in shape, comprised in the top part of the base 10 of the first immobilization unit 2. The first embodiment of the invention comprises a protuberance 26 in the top part of each half of the base 10 of the first immobilization unit 2, as shown in Figure 3.

As shown in Figure 2, the third locking unit 6 of the second immobilization unit 3 comprises an aligner 20, preferably in the form of a pad, which helps keep the patient's pelvis and lower limbs aligned so that they are immobilized in the correct position, through the fixing means 7. In the first embodiment, the aligner 20 is detachable to make cleaning work easier. The aligner 20, as shown in Figure 6, is disposed between the patient's legs.

The first embodiment of the immobilization device 1 of the invention also comprises, in the lower part, approximately at the level of the feet, additional fixing means 8, which are mainly T-shaped, to immobilize the patient's ankles and feet, replacing the splints known in the prior art.

Thanks to the immobilization device 1 of the invention the need to use auxiliary elements such as collars, splints, short rigid tables or long rigid tables is reduced, thereby creating more space in the ambulance and making it easier for the members of the rescue team to go about their work. The three locking units 4, 5 and 6 of the immobilization device 1 cooperate to keep the patient immobilized in the ideal position. Normally the immobilization device 1 is supported on a surface, and in order for the members of the rescue team to handle said device 1 , at least the first immobilization unit 2 comprises in its lower part a plurality of support protuberances 1 1 , as shown in Figure 3, that enable a gap between the first immobilization unit 2 and the support surface, a gap sufficiently large for the members of the rescue team to put their hands in. The second immobilization unit 3 may also comprise similar support protuberances.

The immobilization device 1 is made easier to handle by the fact that it comprises gripping means that comprise a plurality of holes 21 disposed on the perimeter, both in the first immobilization unit 2 and in the second immobilization unit 3, through which the rescue team members may put their hands. The first embodiment of the invention also comprises at least one set of handles 22 disposed on one of the ends of the device 1 . Alternatively, the device 1 may also comprise another set of handles 22 on the opposite end. Said handles 22 make it easier to transport the patient as they balance the forces better.

As an alternative, in a third embodiment, the immobilization device 1 of the invention comprises auxiliary fastening means, not shown in the figures, which may be fixed to hitching means provided, for example, in an helicopter.

As an additional alternative, in a fourth embodiment, the second immobilization unit 3 comprises sliding means (not shown in the figures), preferably in the form of wheels. The wheels may be pulled out and/or height-adjustable, so that the immobilization device 1 of the invention may replace the stretcher traditionally known in the prior art.

As shown in Figure 2, and in further detail in Figure 3, the locking means 17 of the second immobilization unit 3 comprise support means 18 that cooperate with the first immobilization unit 2 to keep said first immobilization unit 2 in an inclined position when the immobilization unit 2 pivots according to a transverse axis 19 formed between the connection of the first immobilization unit 2 and the second immobilization unit 3, being positioned approximately at the level of the patient's hips or pelvis. This option is very useful for incorporating the patient. To achieve this, first of all the first immobilization unit 2 is lifted pivoting in relation to the axis 19, and then the support means 18 are rotated upwards until a protuberance 23 comprised in the support means 18 is housed in a housing disposed in the rear part of the base 10 of the first immobilization unit 2. The first immobilization unit 2 may have various housings at different levels to enable different degrees of inclination. This feature is also advantageous for transferring patients in a safe and comfortable manner to a hospital, residence, rehabilitation centre, etc. The immobilization device 1 of the invention is manufactured from a light, radio- transparent and floating material. As it is radio-transparent, there is no need to transfer the patient to another unit or stretcher in order to be explored by X-ray or by a magnetic resonance. In extreme cases, the patient may be operated in theatre on the immobilization device 1 .

The immobilization device 1 of the invention avoids the unnecessary movements of the patient until having a complete and definitive diagnosis, thereby reducing the risk of causing further injury or even aggravating the injuries already suffered. When the rescue takes place in an area where there is water, the immobilization device 1 of the invention may also be used, as it floats. In such cases, the patient is supported on the immobilization device 1 or only the first immobilization unit 2. As the flaps 9 are hinged, the patient may be immobilized while leaving the abdomen area free in the event that there is a need for the patient to undergo cardiorespiratory or cardiopulmonary resuscitation.

To make the immobilization device 1 of the invention easier to use, it may comprise colour codes to guide the rescue team members when immobilizing the patient. For example, the fixing means 7 may thus be coloured so that the rescue team members are able to identify which fixing means 7 have to be connected to each other. In addition, the device 1 may optionally comprise bright colours or reflective elements to enable the rapid identification of the device 1 .

"Rescue team members" are defined as any personnel involved in the rescue or transfer of a patient. In other words, the immobilization device 1 of the invention is so intuitive and easy-to-use that it is suitable for use by both qualified health personnel and non-health personnel. The immobilization device 1 is suitable for forming part of first aid equipment and may be located in specific places that are, for example, much frequented, such as shopping centres, airports, sports centres, casinos, schools, colleges, universities, sports clubs and associations etc as well as, evidently, in ambulances and hospitals. It is also an ideal tool for use by lifeguards in swimming pools and on beaches.

The immobilization device 1 of the invention is detachable, which means that the space required for its storage is considerably reduced. In this respect, in the first embodiment, the second immobilization unit 3 is detachable, so that the locking means 17, the coupling means 16 and the third locking unit 6, along with the first immobilization unit 2, may be stacked for their storage. This feature also makes it easier to clean the immobilization device 1 . Alternatively, the second immobilization unit 3 may also be fitted together, with the result that the coupling means 16 slide along some sliding means 30, preferably in the form of holes, until the locking means 17 come up against the third locking unit 6. To assemble the second immobilization unit 3 all that is required is to pull on the locking means 17 until the coupling means 16 reach the end of their path.
