Description of the embodiments

[0035] The drawings and description below contain, for the most part, elements of a certain character. They may therefore not only serve to better understand this disclosure, but also contribute to its definition, if necessary.

[0036] Also, the present disclosure relates to a stretcher device 1 for assisting in lifting a person from the ground, having two removable parts. The stretcher comprises a first part and a second part, configured to be assembled in a service position in which said parts form a stretcher having a longitudinal direction.

[0037] The stretcher according to this disclosure may be part of the stretcher equipment mentioned in standard NF EN1865-4 relating to transport chairs and NF EN 1865-5 relating to stretcher support tables applicable to firefighters and civil security.

[0038] A person on the ground is, generally speaking, a person to be assisted, for example a victim or a patient, in a sitting or lying position, on the ground or on any surface. The person on the ground typically has an average reference size, between 150 and 190 cm, and 50 and 150 kg.

[0039] The term service position means a position in which the elements of the stretcher are assembled, for example as seen in figures 1, 2 and 5, in particular under the person, and allow the person to be raised from the ground, in a sitting or lying position.

[0040] The first part of the stretcher is a support part for the person's torso 2, and the second part of the stretcher is a support part for the person's legs 3.

[0041] In the service position of the assembled stretcher, according to figures 1, 2 and 5, the torso support part 2 is configured to be slid under the head, the torso and up to the pelvis of the person, the leg support part 3 is configured to be slid under the thighs of the person if he is in a sitting position on the stretcher, and to be slid under the thighs, knees, calves and feet of the person if the person is in a lying position on the stretcher.

[0042] The stretcher comprises a removable fastening system 23, visible in figure 3, comprising at least a first fastening part 23A secured to an assembly edge of the bust support part and at least a second fastening part 23B secured to an assembly edge of the second leg support part 3.

[0043] As illustrated in Figure 4, the removable fixing system 23 ensures the assembly of the stretcher in the longitudinal direction, where the first fixing part 23A and the second fixing part 23B cooperate mutually to ensure the assembly of the first support part of the bust 2 and the second leg support part 3 in the longitudinal direction of the stretcher. Said leg support part 3 is then assembled as an extension of said bust support part 2.

[0044] A removable fastening system 23 with quick and simple closing / opening is preferred in order to facilitate the assembly and disassembly operations of the stretcher. In particular, the removable fastening system 23 must be effective and simple to use in assistance and / or emergency situations, for example on terrain that is difficult to access, for a particular position of the person on the ground, and / or for variable sizes of the person.

[0045] Thus, according to a preferred embodiment, the fastening portions 23A and 23B comprise self-gripping fasteners of mutually engaging loops and hooks, known in particular by the brand Velcro®. The self-gripping fasteners of the fastening portions 23A and 23B may be further reinforced by elastic, clip-on interlocking portions, such as clip buckles and tightening straps.

[0046] Such a design of the stretcher device advantageously makes it possible, from a disassembled state of the torso support part 2 and the leg support part, to lift the individual by the following steps: - / A / slide said leg support part 3 under the thighs in particular of the lying (or sitting) person and slide said bust support part 2 under the bust, in particular of the lying (or sitting) person, - / B / assembling under the person lying down or sitting down, said bust support part 2 and said leg support part 3 in extension in the longitudinal direction, by cooperation of the first fixing part 23A and the second fixing part 23B, - / D / grab the stretcher and lift the said person lying on the stretcher.

[0047] Such a lifting process makes it possible to limit the handling of the individual to place them on the stretcher, and in particular makes it possible to avoid having to lift the individual entirely to place them on the stretcher.

[0048] According to an advantageous embodiment of the present disclosure and as illustrated in Figures 1, 2, and 5, the bust support part 2 and the leg support part 3 form between them once assembled in the service position a free space L extending between the assembly edges of the fixing parts 23A and 23B. The free space L is configured to leave support on the ground for the person's buttocks. More precisely, the free space L is placed at the level of the person's buttocks and up to the fold between the person's buttocks and thighs.

[0049] According to the inventor's findings, such a space left free between the two removable parts in the center of the stretcher is particularly advantageous, because the transverse separation formed by the free space L between the bust support 2 and leg support 3 parts makes it possible to place each support part of the stretcher under the body of the person on the ground in a single movement, where the bust support part 2 is placed under the bust of the person and the leg support part 3 is placed under the bust of the person. leg support 3 is placed under the person's legs, and advantageously without requiring the individual's buttocks to be lifted.

[0050] The free space L thus ensures easy positioning and assembly of the stretcher device 1 around the person's buttocks without having to lift the person's body entirely off the ground. This reduces handling of the person and improves the speed of intervention.

[0051] More specifically, there is no need to risk rotation of the body by lifting a first longitudinal side of the person's body and then a second longitudinal side of the person's body when inserting and assembling the two torso and leg support parts.

[0052] In addition, as clearly visible in Figure 4, the first fixing part 23A and the second fixing part 23B of the removable fixing system 23 are preferably easily accessible. For this purpose, the two fixing parts 23A and 23B are arranged close to the longitudinal sides of the stretcher, in the transverse direction, and preferably not at the central part forming the free space, located in a median zone, in the transverse direction, between the two longitudinal edges.

[0053] According to one embodiment, the stretcher has in the assembled state: - a total length in the longitudinal direction, when the bust 2 and leg 3 support parts are assembled in the service position, preferably between 195 and 210 cm: - a width of approximately 80 cm in the transverse direction, preferably between 80 cm and 110 cm. According to an illustrated embodiment, the bust support part 2 and the leg support part 3 may, in the longitudinal direction, have different dimensions: the length of the leg support part 3 may typically be greater than the length of the bust support part 2. According to another embodiment, not illustrated, the two parts 2 and 3 may have identical lengths.

[0054] Especially ; - the bust support part 2 is of dimension between 80 and 95 cm in the longitudinal direction, - the leg support part 3 has a dimension between 100 and 115 cm in the longitudinal direction.

[0055] The free space L between the assembled bust support 2 and leg support 3 parts in their service position may be approximately 15 cm in size in the longitudinal direction and approximately 40 cm in size in the transverse direction, and the removable fixing system 23 is approximately 15 cm in size in the longitudinal direction, and approximately 15 cm in size in the transverse direction.

[0056] Such dimensions are compatible with the objectives pursued, namely to provide a stretcher which ensures the lifting of a person, for different reference sizes and dimensions of the person, for example for person weights between 50 and 150 kg.

[0057] It is also possible to produce stretcher versions of different dimensions better adapted to the proportions of the body on a case-by-case basis, for example a bariatric version specifically adapted for very large people weighing over 150 kg.

[0058] In particular, in the case of the bariatric version: - the bust support part 2 is of size between 80 and 95 cm in the longitudinal direction, and of size between 120 and 150 cm in the transverse direction; - the leg support part 3 has a dimension between 100 and 115 cm in the longitudinal direction, and a dimension between 120 and 150 cm in the transverse direction; - the removable fixing system 23 is approximately 30 cm in size in the longitudinal direction, and approximately 30 cm in size in the transverse direction; - the free space L between the bust support 2 and leg support 3 parts assembled in their service position may be approximately 30 cm in size in the longitudinal direction, and approximately 60 cm in size in the transverse direction.

[0059] According to a preferred embodiment, the bust support 2 and leg support 3 parts preferably comprise or / are made of flexible materials, typically flexible tarpaulin, in particular vinyl.

[0060] According to a preferred embodiment, the flexible materials are radiolucent.

[0061] Such a stretcher device made of soft materials is preferred because it is advantageous in several respects: - the materials are preferably impermeable, and thus avoid the long-term incorporation into the stretcher device of mold and / or microorganisms, particularly due to bodily fluids; - they are smooth and are therefore easier to slide under the person to be lifted, and also quick to clean; - they allow electromagnetic radiation to pass through, so the stretcher can be left in place under the person during X-ray examinations; - the materials respond to a compaction problem because they are light and flexible, easy to transport and adapt to different surfaces and situations; - the materials are also inexpensive, and do not require special manufacturing processes; - they comply with the NF EN1865-4 standard relating to transport chairs and NF EN 1865-5 relating to stretcher support tables applicable to firefighters and civil security.

[0062] Such a design in flexible materials also allows the stretcher to be easily deployed and placed on surfaces that are even uneven and / or difficult to access, for example on natural terrain, for example in forests or mountains.

[0063] In addition, the soft materials enable the stretcher device to be stored efficiently. As shown in Figure 7, the soft material stretcher comprising the torso support portion 2 and the leg support portion 3 assembled in the service position, is configured to be rolled up in the longitudinal direction into a storage position, forming a roll-up. The stretcher device 1 further comprises a roll-up holding system 24.

[0064] According to one embodiment, the winding holding system 24 illustrated in FIG. 2 preferably comprises at least one self-gripping closure of mutually engaging loops and hooks, known in particular by the brand Velcro®.

[0065] In particular, the winding holding system 24 may comprise: - a self-latching closure comprising a strip of loops secured to a first face and a strip of hooks secured to a second face of the bust support part 2, so that the two strips are mutually engaging when the stretcher is rolled up longitudinally starting from a lower end of the leg support part 3, and / or - a hook-and-loop fastener comprising a strip of loops secured to a first face and a strip of hooks secured to a second face of the leg support portion 3, so that the two strips are mutually engaging when the stretcher is rolled up longitudinally starting from an upper end of the bust support portion 2.

[0066] According to an alternative embodiment, the stretcher 1 may be provided with a so-called "shell" system, similar to a system for a vacuum immobilizing mattress (MID), in order to immobilize the body of the person on the stretcher while respecting the axis of the spine. In such an embodiment, the two bust 2 and leg 3 support parts of the shell stretcher are designed as sealed compartments, made of flexible materials and each filled with a multitude of balls, in particular polystyrene. Preferably, the stretcher further comprises one or more inflation and deflation valves, for example each located at one end of the bust part 2 and the leg part 3.The stretcher can then preferably self-inflate via the valves, allowing the stretcher to be shaped by moving the balls to envelop the person's body, then depressurized by suction of air, pressing the balls against each other to form a rigid structure around the person's body. When flexible, the stretcher, including both the torso support 2 and leg support parts, can be rolled into the storage position.

[0067] As seen in Figures 1 and 5, the stretcher device 1 may further comprise a system of securing straps to hold the person in place once placed on the assembled torso and leg support parts in the service position: - the bust support portion 2 may comprise a first securing strap 21 extending in the transverse direction of the stretcher, configured to hold the person's bust against the bust support portion 2 and / or, - the leg support portion 3 may comprise a securing strap 31 extending in the transverse direction of the stretcher, and configured to hold the person's legs against the leg support portion 3.

[0068] According to a first embodiment, the stretcher device 1 may further comprise a third securing strap extending in the transverse direction of the stretcher, configured to hold the calves and feet of the person against the leg support portion 3.

[0069] According to a preferred embodiment, the securing straps are made of resistant textile materials, such as polyester, polyamide, aramid.

[0070] The securing straps also preferably include a clip buckle attachment system, in particular plastic or metal, so that they can be quickly and easily closed and opened, as well as a tightening means, such as a tightening buckle, in particular plastic or metal, to ensure that the person is held on the stretcher.

[0071] According to an embodiment as illustrated in Figure 7, one of the securing straps 21 or 31 is left free outside the stretcher once the latter is rolled up in the storage position. The securing strap thus left free is advantageously used as a carrying shoulder strap when the device is rolled up on itself. The stretcher device 1 comprises several pairs of handles 22 distributed around the periphery of the stretcher, illustrated in Figures 1 and 2 in particular.

[0072] According to a possible embodiment, the stretcher device 1 comprises at least one pair of handles located on the rear face of the bust support part 2 as well as handles distributed around the periphery of the bust support part 2, in particular three pairs of handles, and handles distributed around the periphery of the leg support part 3, in particular three pairs of handles.

[0073] We prefer a design where the handles are distributed evenly across the entire stretcher. In more detail, on the bust support part 2: - a pair of handles is located at the level of the person's head, - a pair of handles is located at the person's chest level, - a pair of handles is located at the person's waist level, - a pair of handles is located at the person's shoulders on the back side of the bust support part 2. Likewise, on the leg support part 3: - a pair of handles is located at the level of the person's thighs; - a pair of handles is located at the person's knees; - a pair of handles is located at the person's feet.

[0074] According to another preferred embodiment, the pairs of handles 22 on the periphery of the stretcher are, for example, made of resistant textile materials, polyester, polyamide, aramid.

[0075] According to another preferred embodiment, as illustrated in Figure 2, at least the pair of handles located at the level of the shoulders of the person on the rear face of the bust support part 2 and at least the pair of handles located at the level of the thighs of the person on the periphery of the leg support part 3 are reinforced by semi-rigid or rigid materials, for example heat-welded plastic reinforcements.

[0076] According to another preferred embodiment, three pairs of handles are reinforced with semi-rigid materials heat-sealed on the bust support part 2, and three pairs of handles are reinforced with semi-rigid materials heat-sealed on the leg support part 3.

[0077] According to another embodiment, a pair of handles may be added between the pair of handles at the thighs and the pair of handles at the knees of the person on the leg support part 3.

[0078] According to the inventor's findings, the pairs of heat-sealed, semi-rigid reinforced handles facilitate the handling of the stretcher device supporting the person.

[0079] According to an embodiment of the present disclosure specifically intended for lifting a seated person, and as illustrated in Figure 2 by way of example, the stretcher device 1 comprises a pair of straps 25 having: - a first strap of adjustable length configured to connect the bust support part 2 to the leg support part 3, arranged on a first side of the stretcher, - a second strap of adjustable length configured to connect the bust support part 2 to the leg support part 3, arranged on a second side of the stretcher.

[0080] The pair of straps 25 is configured to be tensioned when lifting a person from a seated position by maintaining an opening angle between the bust support portion 2 and the leg support portion 3 so that said bust support portion 2 and said leg support portion 3 assembled form a seat, and as illustrated by way of example in FIG. 9.

[0081] According to a preferred embodiment, the pair of straps 25 is made of a strong textile material, such as polyester, polyamide, or aramid. The pair of straps 25 also preferably comprises a clip buckle fastening system, in particular plastic or metal, in order to be quickly and easily closed and opened. The pair of straps 25 thus comprises a tightening means, such as a plastic tightening buckle, to allow the opening angle between the two parts supporting the bust 2 and legs 3 to be adjusted and to ensure the rigid holding of the seat-shaped stretcher. A system for adjusting the end of each of the straps 25 may also be provided to adapt the straps 25 to the size, and in particular to the shoulder height, of the person.

[0082] According to the inventor's findings, such a pair of straps 25 is advantageous for facilitating the handling of the stretcher with a person in a seated position. The straps attached and tensioned thus keep the stretcher device 1 in the form of a seat, open according to the opening angle, and thus prevent the seat from deforming or opening suddenly when the person is lifted. In addition, the straps thus tensioned make it possible to advantageously keep the arms of the person seated inside the stretcher.

[0083] As shown in Figure 5, and in general, the leg support portion 3 made of flexible materials can be configured so that it can be folded back on itself in the longitudinal direction, and along a transverse fold axis. The leg support portion 3 thus folded back on itself is of reduced length and advantageously allows transport a person in a sitting position, where the person's thighs are directly supported by the folded part, and the person's knees, calves and feet are left free in the air.

[0084] The two longitudinal ends of the leg support portion 3 each preferably comprise a hook-and-loop fastener comprising a strip of mutually engaging loops and hooks, known by the trademark Velcro®. The strip of loops is located on a first end of the leg support portion 3 and the strip of hooks is located on a second end of the leg support portion 3.

[0085] As illustrated in figures 1, 3 and 4, the leg support part 3 further comprises a system for attaching a bottle, in particular an oxygen bottle 32. The oxygen bottle attachment system 32 comprises two holding parts 33 configured to laterally grip a bottle arranged between the two legs of the person, in a position for holding the oxygen bottle attachment system 32.

[0086] Thus the oxygen bottle attachment system comprises two holding parts 33 preferably comprising flexible materials, such as foam, so that the two holding parts 33 can be retracted flat, as can be understood in Figure 3.

[0087] In particular, the holding parts 33 belonging to the oxygen bottle attachment system 32 are retracted flat: - when the oxygen bottle is removed, prior to folding the stretcher into its storage position, and / or - when the oxygen cylinder is not installed, when it is not necessary, and / or when the stretcher device 1 must accommodate the person in a sitting position, and / or when it is not possible to spread the person's legs in a lying position.

[0088] According to one embodiment, the holding position of the oxygen bottle attachment system 32 is ensured by a hook-and-loop fastener comprising a strip of mutually engaging loops and hooks, arranged transversely to the two holding parts 33 of the oxygen bottle attachment system 32. The hook-and-loop fastener thus locks the two holding parts 33 enclosing a bottle arranged between the person's legs.

[0089] According to another embodiment, the oxygen cylinder attachment system 32 is adjustable and removable, where a hooking system is provided on the leg support portion 3 to allow the adjustment of the height of the oxygen cylinder attachment system 32 according to the space at the person's legs, as well as its removal, and preferably constituted by a hook and loop fastener comprising a strip of mutually engaging loops and hooks of dimension between 10 and 20 cm in the longitudinal direction.

[0090] According to the preceding essential characteristics, such a stretcher device 1 can thus be quickly configured to adapt according to the needs and the situation. The device is quickly and easily set up and assembled under the person. The stretcher in the service position can then be easily grasped and lifted by operators.

[0091] Thus, the present disclosure may relate to a method for lifting a person from the ground, in particular in a lying position according to a first possibility or in a sitting position according to a second possibility, implementing a stretcher device according to the present disclosure.

[0092] The method comprises, from a disassembled state of the bust support part 2 and the leg support part, the following steps: - / A / sliding said leg support part 3 under the thighs of the person typically lying or sitting and sliding said bust support part 2 under the bust of the person typically lying or sitting, - / B / assembling under the person said bust support part 2 and said leg support part 3 in extension in the longitudinal direction, by cooperation of the first fixing part 23A and the second fixing part 23B, - possibly ZCZ fix the chest securing strap 21 around the person's chest and the leg securing strap 31 around the person's legs, - / D / grasp the stretcher, in particular by the handles 22 on the periphery of the stretcher, and lift the said person onto the stretcher.

[0093] According to the second possibility of raising the seated person, visible in figure 9, the method comprises, from a disassembled state of the bust support part 2 and the leg support part 3, the following steps: - step / A / comprises folding said leg support part 3 on itself, sliding said leg support part 3 folded on itself under the thighs of the seated person and placing said bust support part 2 under the bust of the seated person and / or in extension along the longitudinal direction of said leg support part 3 folded on itself, - step / B / comprises assembling under the seated person said bust support part 2 and said leg support part 3 folded on itself in extension in the longitudinal direction, by cooperation of the first fixing part 23A and the second fixing part 23B, fixing the pair of straps 25 to connect the bust support part 2 to the leg support part 3 folded on itself, and tensioning said pair of straps 25 in order to maintain the opening angle between the bust support part 2 and the leg support part 3 folded on itself, so that said assembled bust support parts 2 and legs 3 form a seat under the seated person.

[0094] Generally, for the first or second possibility, step / A / is carried out initially by slightly lifting, as little as possible depending on the state of health of the person lying or sitting, the person's bust, in order to be able to slide the bust support part 2 under the person's bust, and in a second step by slightly lifting, as little as possible depending on the state of health of the person, the person's legs in order to be able to slide the leg support part 3 under the person's legs. If the person has a specific injury, for example to the legs, it goes without saying that the legs should be handled as little as possible.

[0095] During step / A / , the two bust 2 and leg 3 support parts must be positioned so that the free space L is well located at the level of the buttocks of the person lying or sitting, in order to ensure the correct assembly of the entire stretcher device. Thus, during the installation of the removable fixing system 23, the fixing parts 23A and 23B should naturally be facing each other.

[0096] Steps / B / and / C / do not require manipulation of the vital parts of the person on the stretcher, namely the person's head, torso / back, or legs. In addition, the stretcher is configured so that in any lying or sitting position, the person's arms and legs should not interfere with access to the various fasteners and straps.

[0097] The sub-steps of steps / A / , / B / and / C / involving two elements to be fixed or joined, can be carried out in any order, for example in step / A / , the bust support part 2 can be slid under the person's bust first, then followed by the leg support part 3 slid under the person's legs, or vice versa.

[0098] Operations / A / to / D / are preferably performed by at least two operators / rescuers so that the person is handled primarily by a first operator while a second operator slides the stretcher device under the person. Operations / B / and / C / may be performed by one or more operators.

[0099] Depending on the person's state of health, and / or their size, and / or their position, and / or the surface / ground on which they are located, it may be necessary to use more than two operators, particularly for steps / A / and / D / .

[0100] During steps / A / to / D / , the at least two operators are positioned on either side of the stretcher, for example, at least one first operator is located on the periphery of the stretcher on the right, and at least one second operator is located on the periphery of the stretcher on the left, or a first operator is located at the head of the person to be lifted, and a second operator is located at the feet of the person to be lifted. During step / D / , the operators grasp the nearest pairs of handles in front of them, preferably the pairs of reinforced handles at the shoulders and thighs, to lift the stretcher device and the person to be lifted.

[0101] During step / A / of the second possibility where the person is in a seated position, the leg support part 3 is folded back on itself before being slid under the legs of the seated person, as illustrated in Figure 5. This sub-step is carried out by folding down in the longitudinal direction of the stretcher, the lower end of the leg support part 3 onto the upper end of the leg support part 3. The two ends are preferably held together by their hook-and-loop closure system.

[0102] The placement of an oxygen cylinder on the oxygen cylinder attachment system 32 on the leg support part 3, is preferably done between the lifting steps / B / and / D / of the first possibility, once the person in the lying position is placed on the stretcher device assembled in the service position. The oxygen cylinder is added to the stretcher device only if the health condition of the person requires and / or allows it, that is to say, if the person's legs can be slightly spread apart to allow the insertion of the cylinder between them.

[0103] Once the person is in position on the stretcher, the stretcher device and transported person assembly can be moved to a destination by the operators. When the stretcher device and transported person assembly reaches its destination, the assembly is gently lowered by the operators onto a new destination surface, preferably a flat surface. The stretcher device is then easily disassembled and removed from under the person.

[0104] Once the lifting and transport operations of the person are completed, the stretcher device, previously disassembled under the person, can be quickly reassembled according to steps ZBZ and ZCZ on any surface, without the person, then be rolled up in the longitudinal direction and placed in its storage position, held by the winding holding system 24.
