Definitions
- the present invention relates to a device for supporting a human body in a lying and immobile position.
- the invention will be more particularly described with reference to the case of patients in a hospital environment and more particularly in an intensive care unit, the latter being in a prone position and immersed in a coma artificial.
- ARDS acute respiratory distress syndrome
- a known technique for improving the condition of a patient already placed on respiratory assistance is to put him in the ventral decubitus position, which corresponds to a position lying on his stomach. This position promotes the deployment of the lungs compared to a position lying on your back. The patient is then in a state of artificial coma and must remain in this position for several hours, the maneuver being regularly reproduced.
- the technique currently used in hospitals to place the patient in the prone position consists of placing wedges to elevate the patient and clear his rib cage to allow him to breathe.
- the wedges are most often objects made of foam or gel and are supplemented by spontaneous confections of rolled sheets to free passages for the various connections necessary for the survival of the patient. These connections are, for example, necessary for the respiratory aid he receives. These are still the various catheters for infusion or various probes or electrodes for monitoring the patient's constants.
- US Patent 6047420 describes a support system for the head and the bust, the parts of which come into contact with the skin are flexible.
- Patent application DE 10 2009 004 604 describes a set of wedges for supporting a body in the prone position.
- Patent application CN 109498317 describes another system for supporting a body in the prone position.
- the inventors have thus set themselves the task of proposing a device allowing a long-term lying motionless stay for a hospitalized patient by limiting the risk of pressure sores appearing and by allowing access to all areas of the body requiring a connection by catheters, probes, electrodes or other devices useful for the care of the patient.
- a device for supporting a human body in the lying position consisting of at least one shoulder support module and at least one at least one pelvis support module, said at least one shoulder support module and said at least one pelvis support module consisting of at least one first part coming into contact with the human body, said at least one first part each forming a pneumatic cavity, said at least a first part comprising a valve and said at least a first part of at least one shoulder support module being maintained at a pressure of less than 0.04 bar under the weight of the human body .
- the device comprises at least one head support module, said at least one head support module consisting of at least a first part coming into contact with the human body, said at least one first part forming a pneumatic cavity, said at least a first part of said at least one head support module comprising a valve and at least said first part being maintained at a pressure of less than 0.04 bar under the weight of the human body.
- the device comprises at least one leg support module, said at least one leg support module consisting of at least a first part coming into contact with the human body, said at least a first part forming a pneumatic cavity, said at least a first part of said at least one leg support module comprising a valve and at least said first part being maintained at a pressure of less than 0.04 bar under the weight of the human body.
- At least a first part of at least one support module for a part of the human body and more preferably at least one of the first parts of the head support modules, shoulder support and / or leg support are maintained at a pressure less than or equal to 0.03 bar under the weight of the human body.
- At least a first part of at least one support module for a part of the human body and more preferably, at least one of the first parts of the modules of head support, shoulder support, pelvis support and/or leg support consists of at least one sheet of thermoplastic polymer preferably having a modulus of elasticity under tension at 10% elongation less than 50MPa.
- the measurements of moduli of elasticity under tension at 10% elongation are carried out according to the DIN 53504 standard.
- the sheet of thermoplastic polymer has a modulus of elasticity under tension at 10% elongation of less than 25 MPa.
- the sheet of thermoplastic polymer has a thickness of less than 1 mm and more preferably less than 0.5 mm.
- Such a material allows, in known manner, the simple production of an element having a sealed cavity that can be pressurized.
- a particularly suitable material is a thermoplastic polyurethane. It is possible to produce heat seals by bringing the sheet locally to the melting temperature. The rigid properties of the sheet will help to reduce the risk of pressure sores when it comes into contact with the skin.
- At least one support module for a part of the human body and more preferably at least one of the first parts of the head support, support shoulders, pelvis support and/or leg support consists of at least two thermoplastic polymer sheets, at least one of the thermoplastic polymer sheets being reinforced.
- This reinforcement can be based on fibers or fabrics and results in a sheet of thermoplastic polymer that is more rigid than that having a modulus of elasticity under tension at 10% elongation of less than 50 MPa and which advantageously will not come into contact with the patient's skin.
- At least one support module for a part of the human body comprises a second part supporting the first part, the second part preferably being made up of a deformable structure and preferably comprising means for stabilize the first part.
- the deformable nature of the structure constituting the second part of at least one support module for a part of the human body contributes to patient comfort and to the reduction of the risk of pressure sores appearing.
- At least a first part of at least one support module for a part of the human body and advantageously also the first part of the head support, shoulder support, support pelvis and leg support include a valve which ensures maintenance at the required pressure under the effect of the weight of the human body, and any pressure control during use of the device.
- the valve is advantageously positioned to be made accessible in use and not to be able to come into contact with the human body.
- the valve is advantageously still a flap valve to provide the best seal.
- the inflation pressure of the pneumatic cavities of all the modules is advantageously greater than 0.005 bar under the weight of the human body.
- the inflation of at least a first part of at least one support module for a part of the human body and in particular the first part of the head support, shoulder support and pelvis support modules and leg support is advantageously made with an inert and/or purified gas to avoid any risk of additional infection in the event of an accident on one of the modules leading to a leak.
- the shape of at least one support module for a part of the human body and preferably the respective shapes of said at least one shoulder support module, pelvis and leg support each have an axis of symmetry substantially parallel to the axis of symmetry extending from the feet to the head of the supported body.
- the modules being provided to support a body which is substantially symmetrical are advantageously made with a globally symmetrical shape to support the body in the most uniform way possible to best distribute the load and ensure the stability of the body in the position as it is. determined by the nursing staff.
- the second part of at least one support module for a part of the human body and advantageously, the second part of at least one of the head support, head support modules shoulders and/or pelvis support consists of several superimposable elements.
- the realization of a second part in several elements allows first of all to be able to modify the volume and the height of this second part to allow a simple adaptation of the device to the size or diverence of the human body which must be supported or more simply to a position type; if for some reason it is necessary to raise the body, just add one or more elements to obtain the desired dimension.
- this adaptation to the volume can be made with elements of simple shape, these being essentially added to modify the height of the module concerned, only the element coming into contact with the first part having a particular shape to ensure its functions in connection with the first part and the human body.
- the human body is in the ventral decubitus position, that is to say in a position in which the body is substantially lying on its stomach.
- the device for supporting a human body in the lying position thus described according to the invention makes it possible to support a body in a desired position by reducing the risk of pressure sores appearing in the areas of contact with the support modules. and all areas of the body requiring connections or connection to respiratory support systems remain accessible.
- the inventors have indeed been able to demonstrate that the maintenance at the selected pressures of the first parts of the support modules under the weight of the human body, said parts being advantageously made up of at least one sheet of thermoplastic polymer having a modulus of elasticity under tension at 10% elongation of less than 50 MPa, and preferably less than 25 MPa, reduces the risk of pressure sores appearing, said first parts being made with precision to rest on the human body at the desired locations.
- the presence of at least one shoulder support and at least one pelvis support with the precision of the supports obtained also allows, in the case of a ventral decubitus position, the breathing of the individual by releasing his mobile parts of the thorax and abdomen while protecting in particular his genitals.
- the second parts provide the necessary volume to position the human body as desired and the rigidity to ensure stability.
- the first parts whose volume is reduced can be easily maintained at the chosen pressures and carried out with even more precision to rest on the human body at the desired locations.
- the second parts are further provided with means for stabilizing the first parts in the desired positions and thus make it possible on the one hand to guarantee the desired supports and on the other hand to guarantee the stability of these supports.
- These means can be directly linked to the shape of the second parts which can be provided to receive the first parts and prevent their displacement, in particular in the presence of the human body. It is still possible to provide attachment systems between the first and second parts; these may be, for example, systems of the mechanical fastening type using textile hooks and loops, marketed under the “velcro” brand, which are easy to use and allow adjustable positioning.
- the inventors thus think of proposing a device entirely suitable for supporting a human body, in particular in the prone decubitus position, by reducing the risks associated with the appearance of bedsores which, moreover, can be achieved with costs altogether. made acceptable. These low costs further allow the provision of modules of different sizes or shapes for better adaptation to the size and volume of the human body. This choice of module size further optimizes the positioning of the support points of the human body on these modules.
- the second part of at least one support module for a part of the human body is at least partially made up of a polymer foam having a compression stiffness of between 5 KPa and 50 Kpa.
- the compression stiffness is measured according to the ISO 3386/1 standard.
- the second part of at least one support module for a part of the human body is at least partially constituted by a pneumatic cavity, said second part of said at least one support module for a part of the human body comprising a valve, said second part of said at least one support module for a part of the human body being maintained at a pressure of between 0.05 and 1 bar under the weight of the human body.
- the second part of at least one support module for a part of the human body can comprise a pneumatic part, which preferably does not come into contact with the first part. It can for example be one of the superimposable elements described previously.
- a pneumatic part which preferably does not come into contact with the first part.
- the pneumatic part not yet being inflated when the human body is positioned and the volume of the second part being therefore reduced in comparison with its volume in use.
- this pneumatic part constituting the second part is preferably maintained at a pressure of between 0.05 and 1 bar under the weight of the human body.
- At least the areas of at least a first part of at least one support module for a part of the human body and preferably, at least the areas of the first parts of each of the modules head support, shoulder support, pelvis support and leg support, intended to come into contact with the skin are covered with a medical fabric.
- a medical fabric is a fabric usually used in the hospital environment and which is suitable for coming into contact with the patient's skin and therefore deemed to be non-irritating, not carrying possible sources of infections. and easily cleanable with products used in hospitals.
- these fabrics can still be fabrics made in three dimensions of the “XD Spacer Fabrics” type. marketed by the company Baltex and which are already used in medical applications. These three-dimensional fabrics have the advantage of ensuring ventilation at the surface of the skin of the human body in contact with the support module.
- the head support module supports a lateral side of the head, the position of the head being oriented laterally as if the person were looking to the side.
- the head support module is profiled to serve as a support for one side of the head and a recess is provided to leave the ear accessible and free from support constraints.
- the profile is thus advantageously defined to come to rest on certain bones of the skull such as the lateral part of the forehead, the circumference of the ear and the jaws, thus leaving the eyes, the mouth, the nostrils and the ear free either for access to breathing aids or because they are too sensitive to pressure.
- the head support module and preferably the second part also advantageously has blocking zones forming wedges at the level of the forehead and the chin for good support, the head having a natural rotational movement to return to a position of muscle rest.
- the device for supporting a human body in the lying position preferably comprises an additional head support module similar to the previous one which is its image in a mirror to be adapted for supporting the other side of the head.
- the device thus advantageously comprises a right head support module and a left head support module.
- the support of the human body, in particular in the prone position with the head being held in the lateral position, is preferably accompanied by a reversal of the head by approximately 180° at regular intervals to avoid any muscular risk; such an operation requires a head support module for each of the sides and therefore two different modules.
- the first part of the head support module(s) advantageously consists of two sheets of thermoplastic polymer heat-sealed on their periphery, after having been cut to the desired shape, the second part being provided with a similar shape to receive the first part.
- a heat seal also makes it possible to create the recess for the ear.
- a first part thus produced resembles a pneumatic cushion, or even a buoy, due to the recess for the ear, with a particular shape.
- the shoulder support module has an asymmetry between the part oriented towards the bottom of the body and that oriented towards the head to optimize the support of the fixed parts of the body surrounding the chest when breathing.
- the shoulder support module is thus advantageously designed to rest on the fixed parts of the rib cage which are the base of the shoulders, the clavicles and the fixed ribs, leaving the neck, the floating ribs and of the abdomen to allow the patient to breathe.
- the first part of the shoulder support module is advantageously made up of two sheets of thermoplastic polymer heat-sealed on their periphery, after having been cut to the desired shape, the second part being provided with a similar shape to receive the first part.
- the first part thus produced has a shape similar to that of a cushion.
- this shoulder support module between the part oriented towards the bottom of the body and that oriented towards the head therefore optimizes the support by pressing on the fixed zones of the human body during breathing.
- the part oriented towards the bottom of the body advantageously comprises a heat-sealed zone in its central part to locally eliminate the pneumatic cavity and allow to reduce or even eliminate the pressure on the sternum area.
- the first part is advantageously heat-sealed in its central part while allowing a single pneumatic cavity to be maintained in order to maintain a uniform pressure.
- the shoulder support module can be produced in two separate parts, then being transformed into two separate modules, to completely free the central part of the human body.
- This variant has advantages, in particular for connecting electrodes, but can become tricky when positioning the body, especially when it is overweight, to guarantee good positioning and the desired distribution of support.
- the first part of the basin support module comprises a sheet of thermoplastic polymer heat-sealed along the length of two ends to form a tube and the central part of said first part of the module of the pelvis support is partially heat-sealed to form a non-pneumatic zone.
- the first part of the pelvis support module is thus designed to come to bear on the iliac crests and a small area of the lower abdomen, preventing any contact with the genitals and leaving the inguinal regions and upper thighs free to allow the various connections of probes or other catheters.
- the first part of the pelvis support module is thus advantageously made with a tubular shape, the ends of which can be heat-sealed to form a form of the carton type or else each of the ends of the tube can be closed by an additional heat-sealed sheet to close said end.
- the section of the tube can be provided with a different shape or even with a variable section along its length, for example to form two frustoconical parts on either side of the central part.
- the first part of the pelvis support module is positioned on a second part, which is the bulkiest in comparison with the other modules and designed to raise the human body to allow breathing.
- This second part of the pelvis module will be all the more voluminous if the patient shows signs of obesity.
- This second part is again advantageously provided with a V-shape with a relatively flat zone between two inclined branches, the flat zone being provided to receive the central part of the first part.
- This V-shape makes it possible on the one hand to properly position and center the human body and on the other hand, to ensure the support of the pelvis on the iliac crests by avoiding contact with the genitals which remain above and at distance from the flat area to the bottom of the V.
- the first part of the pelvis support module is advantageously heat-sealed in its central part, to avoid putting the genitals under pressure, while allowing keep a single pneumatic cavity in order to maintain a homogeneous pressure.
- the pelvis support module can be made in two separate parts, then being transformed into two separate modules, to completely free the central part of the human body.
- this variant can become difficult when positioning the human body, in particular when the latter is overweight, to guarantee good positioning and the distribution of the supports. wanted.
- the first part or parts of the pelvis support module are maintained at a pressure of between 0.01 and 0.1 bar, under the weight of the human body. Such pressures may be necessary due to the low support surface on the body obtained for this pelvis support module.
- the leg support module comprises a sheet of thermoplastic polymer heat-sealed along the length of two ends to form a tube.
- the ends can be heat-sealed to form a carton-like shape or else each of the ends of the tube can be closed by an additional heat-sealed sheet to close said end.
- the leg support module is designed to rest on the shins and the positioning accuracy is not important, which makes it possible to dispense with a second part, especially since this part of the body is not In principle, it does not need to be raised to allow breathing.
- the essential function of this leg support module is to avoid contact of the toes with the bed or other support on which the device is installed.
- leg support modules with different diameters are advantageously provided.
- the leg support module is provided with a second part. This variant may be necessary in the case of a very large patient for whom the pelvis support module is greatly raised to keep the body in a substantially elongated position.
- the device may comprise additional knee support modules, although the knees are less sensitive to the risk of bedsores. It can then be a single module or two independent modules.
- the knee support module or modules are provided with a second part.
- This variant may be necessary in the case of a very large patient for whom the pelvis support module is greatly raised to keep the body in a substantially elongated position of the body.
- one, several or all of the modules are placed on a plate of great rigidity to confer better stability on the support device.
- Such plates are for example plates already used in the hospital world marketed under the "KOMACEL” brand.
- the invention as it has just been described, in addition to its advantages in terms of reducing the risk of pressure sores appearing, has several advantages, in particular related to the inflatable nature of the constituent parts of the support modules. Indeed, on the one hand, the use of inflatable elements makes it possible to reduce their volumes when they are not used or before use and thus facilitate their storage. Associated with this gain of volume, it becomes possible to store a large number and variety of these elements and thus to have at any time the model best suited to the situation, particularly in terms of variety of shapes.
- the second constituent parts of the support modules are also inflatable elements, in addition to the aforementioned advantages, it becomes possible for the operators to reduce the volume of these second parts, one of the functions of which is in particular to provide volume, and thus facilitate the manipulation of the human body. This is particularly important for patients placed in the prone position who need to be placed on their back regularly; the reduction in volume of the bulkiest parts facilitates such operations.
- the invention also proposes a method for supporting a human body implementing the device as it has just been described according to which, in a first step, the cavity of at least a first part of at least one human body part support module is partially filled with air, in a second step, the human body is placed on said at least one human body part support module and, in a third step, the pressure of said cavity of at least a first part of at least one support module for a part of the human body is regulated at a pressure lower than 0.04 bar.
- At least one human body support module comprising a second part supporting a first part of said human body support module and at least partially forming a pneumatic cavity
- the pressure of said cavity of the second part of said human body support module is regulated to a pressure of between 0.05 and 1 bar.

- Figure 2 further illustrates the first part 7 of the head support module 3. Its shape is similar to the second parts 8D and 8G to be superimposed thereon and it comprises in the same way a recess 13C to leave appear the ear and do not crush it.
- This first part 7 which forms a pneumatic cavity with the shape of a cushion or buoy can be used with the two second parts 8D and 8G provided that the two sheets of thermoplastic polyurethane used are well designed to come into contact with the skin.
- Figure 3 schematically shows in perspective a shoulder support module 4 consisting of a first part 9 forming a cushion-shaped pneumatic cavity and a second part 10 supporting the first part 9.
- the reference 15 indicates a flare to limit the support on the upper part of the abdomen and the sternum to allow breathing.
- Reference 16 indicates a flare to limit pressure on the neck and trachea artery.
- the shoulder support module 4 has an asymmetry between the part oriented towards the flared zone 15 and the part oriented towards the flared zone 16.
- the zones surrounding the flared part 16 are designed to bear on the shoulders and release the neck.
- Figure 4 shows three embodiments of this shoulder support module 4.
- the shoulder support module 4A has a relatively elongated shape and will be particularly suitable for a very large person.
- the modulus of 4B shoulder support has a shape relatively similar to that of the module 4A and will be particularly suitable for a person of smaller build.
- zone 17 which indicates a passage for the inflation gas while the zone 18 indicates a heat-sealed part.
- This zone 18 is provided to limit the pressure on the sternum and the zone 17 makes it possible to balance the pressure exerted on the body 2.
- the last embodiment of the shoulder support module 4C corresponds to an embodiment in two symmetrical parts 19 and 20. As mentioned previously, such an embodiment can allow easy access for certain connections of the electrode type for electrocardiogram. On the other hand, the installation of the human body 2 on these modules is delicate and makes more complex a homogeneous distribution of the supports.
- Figure 5 shows in perspective the second part 12 of the basin support module 5.
- This second part 12 has in its upper part intended to receive the first part 11 a V-shape forming two branches 21 and 22 separated the one from the other by a flat bottom 23.
- Each of the branches 21 and 22 have wedges 24 provided to wedge the first part 11.
- the second parts 8 and 10 of the head support 3 and shoulder support 4 modules can also include additional elements to adapt the height of said second parts 8 and 10.
- Figure 6 shows in perspective the first part 11 of the basin support module 5.
- This first part 11 forms a cylindrical tube which has been closed at both ends 26 by heat sealing.
- This embodiment makes it possible to produce the cylinder by heat-sealing a sheet of thermoplastic polyurethane, the welding being carried out inside the cylinder. In this way, no apparent welding comes into contact with the human body.
- the first part 11 retains a passage zone 27 to ensure equalization of the pressures and a zone 28 is flattened by carrying out appropriate heat sealing to obtain the desired shape.
- the association of this zone 28 of the first part 11 with the zone 23 of the second part 12 will allow centering of the part 11 on the part 12, as illustrated in FIG. 7, and above all creates a zone of non-contact 29 with the human body 2 to protect his genital areas and avoid any contact and support at this level of the body 2.
- Figure 8 illustrates an embodiment of the leg support module 6. This consists of a pneumatic cavity of cylindrical shape closed at both ends 30.
- the cylinder is made as for the first part 11 of the basin support module 5.
- the ends 30 of the cylinder are then heat-sealed to give the appearance of a carton shape.
- Figure 9 schematically illustrates an alternative embodiment of a device 21 for supporting a human body (2) in the prone position.
- This device 21 differs from device 1 of FIG. 1 at the level of the pelvis support module 5.
- the second part 12a is an inflatable element produced in a manner similar to the first part 11.
- its pressure under the weight of the human body in use will be higher than that of the first part and between 0.05 and 1 bar.
- this second part 12b is designed to present a shape similar to the second part 12 represented in FIG. 1, once maintained under pressure under the weight of the human body.
- FIG. 10 thus describes a second part 12b having a V shape with two branches 21b and 22b separated by a flattened zone 23b.
- Such an inflatable element 12b is easily made with sheets of thermoplastic polyurethane by heat-sealing the sheets and adding heat-sealed thermoplastic polyurethane sheets to each of the branches 21b and 22b to form internal walls in the cavity of each of the branches to obtain surfaces relatively flat to receive the first part 11 of the basin support. These heat-sealed walls are put in place before the sealing of each of the branches 21b and 22b by other heat-sealed thermoplastic polyurethane sheets.
- Figure 11 illustrates yet another alternative embodiment similar to that shown in Figure 10.
- the second part 12c is once again an element inflatable whose branches 21c and 22c are made by a succession of flanges forming a V-shaped structure intended to receive the first part 11 of the pelvis support.
- Such a beaded structure is easily made by heat sealing internal walls.
- Figure 12 schematically illustrates another embodiment of a device 31 for supporting a human body 2 in the prone position.
- This device 31 differs from device 1 of FIG. 1 at the level of the pelvis support module 5.
- the second part of this support module does not exist.
- Such a variant embodiment is more particularly suited to the case of a human body with a low diverence for which the pelvis support module 5 consists of only the first part 11, which constitutes a sufficient volume to avoid contact with the abdomen. with the bed and allow the patient to breathe correctly in the prone position.
- the human body 2 placed on the four support modules has a mass of 90 kg.
- the first parts 7, 9 and 11 of the head support 3, shoulder support 4, pelvis support 5 and leg support module 6 modules are partially filled with inflation gas so as to detach the walls of the pneumatic cavities.
- the human body 2 is placed on the support modules and each of the aforementioned pneumatic elements is brought to and maintained at the desired support pressure.
