Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates generally to the field of devices for lifting an individual, in particular the field of two-part stretchers and litters. STATE OF PRIOR ART

[0002] In the event of an accident or fall, the victim may be on the ground and have suffered an injury that prevents them from getting up. In some cases, it is therefore advisable for the victim to move as little as possible to avoid altering the position of their spine, thus preventing further damage or potentially worsening their condition. Once on the scene, first responders must carefully lift the victim from the ground and transport them for further care. Using a stretcher helps reduce the risks associated with handling the victim.

[0003] To limit the risk of aggravating a potential fracture, or even a possible spinal cord injury, during the victim's mobilization or transport, it may be beneficial to immobilize the victim's entire body (including their head) on the stretcher. Therefore, handling the person must be carried out in accordance with regulations, meaning without moving their cervical spine and vertebral column, commonly referred to in emergency medical services as the head-neck-trunk axis.

[0004] Finally , It is common practice for the person, the victim, or the patient to undergo an X-ray examination to determine any potential fractures and injuries. This examination may need to be performed quickly and before the patient is moved from the stretcher to another support; therefore, it is strongly recommended that stretchers be made of radiolucent materials.

[0005] Prior art suggests using a backboard on which the victim or patient is placed in a supine position. Straps are used to immobilize the victim's body on the backboard, and an optional head immobilizer can be used to immobilize the head. The backboard consists of: A rectangular board, roughly the size of a person, made of PVC, preferably radiolucent, water-resistant, and biologically inert (absorption of biological fluids or blood by the material must be impossible to prevent the transmission of infectious germs). This rigid board is equipped with carrying handles and restraint straps to immobilize the victim at the chest, pelvis, and lower limbs.

[0006] The head immobilizer consists of: A head cushion, fixed to the hard surface; Two lateral immobilization blocks; Two head support straps at the forehead and chin.

[0007] One of the drawbacks of this solution is the risk it poses when handling the victim to place them on their back on the backboard. Indeed, it is necessary to lift or roll the victim to position them on the backboard. During this maneuver, the risk of displacing the victim's neck and spine is particularly high, which can lead to a worsening of their condition. Especially when the victim is in a confined space, the maneuver becomes more complex and sometimes difficult to perform in order to place them on the backboard without risking injury.

[0008] Another solution is the use of a scoop stretcher, which is a two-part, separable product. Once assembled, the two parts form a system on which a casualty can be placed and transported. The advantage of this solution lies in the ability to insert one of the two parts of the stretcher on each side under the casualty or patient, thus locking the two parts together once they are already positioned under the patient. This reduces the risky handling required on the patient. The use of such a device is particularly recommended in the following cases: A trauma victim suspected of having a spinal injury needs to be placed on a vacuum mattress; a simple or enhanced bridge cannot be created (lowered area, for example, the person is under a train or vehicle). This device must also allow the victim to be lifted without further trauma and without soiling or dirt (the equipment must be non-oxidizing and easily cleanable). This type of stretcher simplifies the insertion of the two-part stretcher under the person, but the parts can sometimes be difficult to secure together firmly and permanently. Furthermore, gripping such a stretcher can also be more difficult, partly to avoid separating the two parts. Finally, a scoop stretcher does not immobilize a victim, unlike a backboard or vacuum mattress. It is only used to lift and then transport a victim to a backboard or vacuum mattress..

[0009] Patent WO1998037848 describes a patient transport support based on a spoon stretcher and consisting of separable halves to facilitate positioning under the patient's body. It is designed to allow for radiographic examination. The junction area between the halves and the points where the pivot and locking mechanisms are located are offset laterally from the midline or longitudinal midline of the patient support once assembled.

[0010] One drawback of this device is that the central section is too thick during lifting, making it difficult for rescuers to move the victim. The offset hinges necessitate a considerable thickness to accommodate the increased weight resulting from their offset. Furthermore, these hinges and their coupling system result in a transverse assembly of the product, which can pinch the person being lifted and / or cause excessive manipulation during the lifting process. This assembly requires the victim to be moved at the cervical level, posing risks to the spine. This manipulation is also contrary to regulations regarding emergency procedures. Finally, the fastening points are located close to the patient's head and feet, which can be problematic both during assembly and during transport.These fixing devices are generally made of metal, or reinforced with metal, and are not radiolucent for durability reasons, which can cause discomfort during an X-ray.

[0011] Another simple spoon-type stretcher device is proposed by patent GB2502830. This device features two blades with a shape-coordinated joint at their longitudinal ends, allowing them to be joined and held in place by removable straps at the end closest to the patient's head. Once the straps are secured, tightening them allows them to be tucked into a recess so as not to obstruct the operator. The operation can be complex depending on the surrounding space and the urgency of the situation. Indeed, once the blades are joined, the loose straps must be passed through the head structure to lock them in place. This can be complex and require dexterity, in addition to being counterintuitive and time-consuming, especially in emergency situations. The stretcher is typically grasped from the sides, which is a drawback in confined spaces.Indeed, with this type of stretcher, it is necessary to have access to both the longitudinal ends in order to assemble the two parts of the stretcher and pass the straps through said ends, and also to have access to the sides of the stretcher, where the lifting devices are located, in order to lift and transport the person. US2999251 discloses a stretcher comprising two removable lifting devices, which have at least one coupling between each of the lifting devices and each of the longitudinal ends.

[0012] Finally, the device described in US patent 5803087 comprises two separable blades without any form cooperation, held together by non-removable linear bars (integrated into the blades). These bars have a central locking mechanism to secure them together. These non-removable bars may be a hindrance during patient radiography. Furthermore, the blades are flat and meet along their entire length, which can pose problems when positioning each blade on either side of the patient without excessive manipulation and without displacing their head-neck-trunk axis. Finally, the device is grasped on the bars or the sides of the blades, which can be difficult once the patient is placed on the blade assembly, particularly in confined spaces.

[0013] This results in a need for a lifting, transport and immobilization device for a person that is easily handled regardless of the environment in which it is used, and whose use is easy and does not cause risks to the patient's health during handling, and which offers a solid and durable assembly, without the device being a hindrance during an X-ray. DESCRIPTION OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

[0032] In general, the present invention relates to a device (1) for transporting a person comprising a longitudinally extending, preferably concave, support surface (S) on which a person (20) can be transported, the support surface (S) having two lateral edges (230), and two longitudinal ends (210), the device (1) further comprising grasping means (5) of the device (1), the grasping means being removable from said device, the device further having at least one coupling between each of the grasping means (5) and each of the longitudinal ends (210), the device (1) being characterized in that the coupling comprises at least two coupling points of which at least one pivot.

[0033] Preferably, the coupling is configured so that each grasping means can be coupled by a pivoting movement from a first coupling point to the second coupling point.

[0034] It is important to note that such a transport device can be used by first responders both as a stretcher for lifting and transporting a person, and as a rigid board for immobilizing the person. In other words, the person can remain on the device during transport to the hospital, for example by ambulance, without needing to be transferred to another means such as a rigid board or a vacuum mattress.

[0035] The removable coupling allows for less bulk both during transport and during placement of the device under the patient.

[0036] In certain embodiments, said coupling of the grasping means with the longitudinal ends (210) of the surface further comprising locking means (51) capable of locking said grasping means to said coupling points of said ends (210).

[0037] This advantageously allows the grasping means to be locked regardless of the gripping direction and the applied force. Preferably, the locking means include a fastener, a latch, or any other means allowing the grasping means to be reversibly locked, regardless of the direction of the force applied to said grasping means.

[0038] In some embodiments, the grasping means (5) have a length less than 50%, preferably 25%, of the length of the support surface (S). This reduces the overall size of the device, particularly during assembly, but also during transport, especially prior to assembly.

[0039] In some embodiments, the grasping means (5) do not extend into the support surface (S) for a length exceeding 50%, preferably 25% of the length of said support surface (S). This advantageously reduces the overall size of the device, particularly during device assembly.

[0040] In some embodiments, each of the graspable means (5) forms a graspable protruding portion and extends beyond the support surface (S). This advantageously provides an additional grasping zone offset from the support surface (S) and the person, which can improve and simplify patient care in confined spaces. In some embodiments, the graspable protruding portion (5) extends substantially in the same plane as the support surface (S). In other embodiments, the graspable protruding portion extends in a different plane, which in certain situations facilitates grasping.

[0041] Preferably, the graspable means (5) of the device (1) are rigid, which makes it easier to grasp them and to couple them to the longitudinal ends (210) of the surface (S) by pivot.

[0042] In some embodiments, the pivot includes an axis of rotation substantially perpendicular to the plane of the surface (S).

[0043] By "approximately" we mean roughly perpendicular. In all cases, the pivot always has an axis of rotation perpendicular to the coupling plane.

[0044] In some embodiments, the device (1) comprises at least two blades (2) extending along a predominantly longitudinal axis (L) between two ends and each comprising two edges (22, 23), and two longitudinal ends (21), the blades (2) being configured to be assembled reversibly to one another in an assembly position by at least one coupling (3) between two edges (22), parallel to the axis (L), to form said support surface (S), preferably concave, on which a person can be transported, the two longitudinal ends (210) of the support surface (S) being formed by the association of the longitudinal ends (21) of each blade (2), the coupling between each grasping means (5) and each longitudinal end (210) of the surface being made at the ends (21) of each blade (2).

[0045] The longitudinal axis "L" crosses the surface formed by the two blades at the level of its longitudinal median line.

[0046] Advantageously, the presence of two separable blades, or side rails, allows the person to be raised in accordance with regulations, that is, without moving their cervical vertebrae and spine, commonly referred to in rescue as the head-neck-trunk axis.

[0047] It is thus sufficient to couple one end of a gripping means to one end of a first blade, then to connect said gripping means to the end of a second blade, by a pivoting movement.

[0048] In some embodiments, the grasping means (5) form means for assembling said blade assembly position, the coupling of the grasping means with the longitudinal ends (210) of the surface includes locking means suitable for being locked to said ends (21, 210) of the two blades (2).

[0049] The device thus advantageously provides a locking mechanism that can be coupled to the ends of a surface formed by two blades, thereby enabling i) its assembly, ii) its gripping, and iii) the locking of the coupling and therefore the assembly. This allows for a robust, multi-stage assembly, which involves pre-assembling the device by first coupling (3) each of the blades, followed by final assembly by coupling the locking means to the ends of said blades to stiffen and secure the assembly. The final assembly can then be lifted by means of said locking means.Thus, in a cluttered environment, the ability to first assemble the blades with an initial coupling, and then attach the gripping devices to the blades with a second coupling, simplifies operation—a feature often crucial in urgent situations, which is frequently the case when using this type of device. Assembly is also simpler and faster when the device is assembled directly beneath the patient being transported.

[0050] In some embodiments, the grasping means (5) have a length less than 25% of the length of the support surface (S). This reduces the overall size of the device, particularly during assembly, but also during transport, especially prior to assembly.

[0051] In some embodiments, the grasping means (5) do not extend into the support surface (S) for a length exceeding 25% of the length of said support surface (S). This advantageously reduces the overall size of the device, particularly during device assembly.

[0052] In certain embodiments, the device (1) includes, in the assembly position, a space between said surface and each of the grasping means, in particular by means of a notch on each of the blades near the points where said grasping means (5) are made secure to the ends (21) of the blades (2).

[0053] It is understood that the surface (S) formed by the assembly of the two longitudinal blades extends along the longitudinal axis (L) substantially on a support plane (X), the longitudinal axis (L) being a straight line contained in the plane (X).

[0054] Preferably, the graspable protruding portion can be gripped regardless of the direction of gripping. This is facilitated when the graspable protruding portion has a recess. This advantageously simplifies gripping the device (1), regardless of the surrounding obstructions (in a wrecked car, under a train, or under debris, etc.).

[0055] A support surface is understood to be a surface whose size and shape are at least capable of supporting the body of a person.

[0056] Attaching the grasping means to the longitudinal ends (210) of the support surface allows the grasping mechanism to be positioned away from the person's body. Since the coupling is reversible, the grasping means can be made of non-radiolucent metal and removed before radiography, thus making the assembly of the blades on which the person is lying radiolucent.

[0057] The coupling (3) of the blades, preferably by couplers (3, 31, 32), is made at the ends (21) of the blades (2) so as not to be under the person. This allows the operator to visually confirm the correct coupling of the blades. This avoids the need for complex manipulation of the person and the blades to form the support surface, and furthermore, prevents this manipulation from being performed blindly.

[0058] Furthermore, the remote placement of the grasping devices (5) eliminates the need for complex manipulation of the person and the blades to assemble and carry said blades (2), as the coupling of the grasping devices (5) with said blades (2) then presents no risk to the person. In this way, the operator, generally a first responder, has a visual overview of the entire operation, never working blind, which further reduces the risk of worsening the person's condition.

[0059] In embodiments, the surface formed by the assembly of the two blades includes an orifice (4) which extends along the longitudinal axis (L) over at least a part of said surface (S).

[0060] Advantageously, this allows for easier placement of the blades on each side and their assembly without risk of pinching the person's body. It also allows for a visual examination of the person's back at the level of the opening once it has been placed on the device (1) and raised. An opening is understood to be any open area or surface, which can have various shapes. Thus, the opening can be circular, oblong, rectangular, or any other shape that improves the visual examination of the person without risk of pinching them during blade assembly, while maintaining good resistance to the stresses caused by the person's weight.

[0061] Preferably, the size of the orifice can vary between 100 and 180 cm in length, preferably between 120 and 160 cm, more preferably 139 cm, and between 1 and 6 cm in width, preferably 1.5 and 3 cm, more preferably 2 cm. The orifice (4) is preferably oblong in shape.

[0062] In embodiments, as illustrated for example in a non-limiting way in the figure 1 , the assembly of the two blades (2) of the device (1) by couplers (31, 32, figure 2A And 3 ) forms a stretcher-forming device (1) comprising a support surface (S) on which a person can lie. Operators can lift and carry the device (1) by means of grips (7) formed by openings along the lateral edges (230) of the surface (S) of said device, or by means of grips (5) arranged at each end of the device.

[0063] In some embodiments, the surface is slightly concave to improve user comfort. In some non-limiting embodiments, the incline of the concave surface is shallow at the user's head position to further improve comfort.

[0064] In some embodiments, the device has a length measuring between approximately 175cm and 220cm, preferably between approximately 185 and 195cm, and a width measuring between approximately 40 and 60cm, preferably between 45 and 55cm.

[0065] Thus, the blades (2) each comprise at least one central longitudinal edge (22) and one lateral longitudinal edge (23), the coupling (3) being carried out at the level of the central longitudinal edges (22), and the free lateral longitudinal edges (23) forming the lateral longitudinal edges (230) of the surface (S).

[0066] In embodiments, each blade (2) includes at each of its two longitudinal ends (21) a projecting member (51), and each grasping means (5) includes two ends (50), each of the ends (50) being complementary to one of said projecting members (51), and capable of being made secure and locked onto one of said projecting members (51) by a locking means (52).

[0067] Doubling the means of securing and locking these parts, and offsetting them, makes it possible to both stiffen the whole structure without the blades having a very significant thickness.

[0068] More specifically, the figure 2Aillustrates a non-limiting embodiment of the present invention, in which a locking means (5), forming a hoop, locks the assembly of the two blades (2). The hoop (5) comprises an end (50) forming an arm and is locked onto a projecting member (51) of the blade (2) by means of a latch (52) which pinches said projecting member (51).

[0069] In embodiments, as illustrated for example in a non-limiting way in figures 2A, 2B And 3 The device further includes an additional means for securing the grasping means (5), for example, a recess or indentation present at each longitudinal end of the support surface (210) on the edge of the device, the grasping means (5) being configured to be press-fitted into said additional means for securing the means (9). Preferably, each blade (2) includes an additional means for securing the means (9).

[0070] This allows for stiffening the assembly of the blades (2) with the gripping means, in addition to locking the gripping means onto said blades (2). Advantageously, this also allows the stresses to be distributed over the entire periphery of the longitudinal ends (21) of the blades (2) rather than concentrating them on the gripping points.

[0071] As shown in the figure 3 It is possible to force the gripping means (5) into the additional fastening means (9) by pivoting it after locking it on one side onto a protruding member (51) of a blade (2), the protruding member (51) then representing the pivot point. The fastening means (9) thus allows the device (1) to have an additional fastening in addition to the protruding members (51) that complement the locking means (52).

[0072] In certain embodiments, as illustrated for example in a non-limiting way in Figures 4A and 4BThe grasping means (5), forming a protruding graspable portion, can be produced by molding in which a network of ribs (54) is created, optimized to improve resistance to stress without significantly increasing the weight. The grasping means (5) can be formed from two independently molded parts.

[0073] In embodiments, as illustrated for example in a non-limiting way in the figure 4CEach end (50) of the grasping means (5) comprises an arm including at least one locking latch (52), complementary to one of the projecting members (51), the latch (52) being movable between a closed, or rest, position in which the locking means is locked and an open position in which the locking means is removable. Preferably, the locking means (52) further comprises a return element for the latch (52) in the closed position, for example, a spring. This allows the operator, for example, a rescuer, to easily and reliably lock and unlock the locking means (52) during assembly. Preferably, the locking means comprises a locking indicator, for example, a visual or audible indicator.Preferably, the locking means (52) includes an audible indicator such as a locking ratchet capable of emitting a sound when locked, for example by clipping.

[0074] In preferred embodiments, the protruding members (51) and the locking means (52) are configured to be coupled and locked together outside the support surface formed by the blade assembly (2). This advantageously allows the operator to perform the coupling without being hindered by the person, and without having to manipulate it.

[0075] In embodiments such as those illustrated, for example, in a non-limiting manner, Figures 2A And 3Each blade (2) comprises a coupling (3), preferably at each longitudinal end of the blade (21). Each coupling (3) consists of a coupler from one blade and a coupler from the other blade to allow the two blades (2) to be joined. The complementary couplers (31, 32) preferably form a pair consisting of a protruding coupling element (31) on one blade and a corresponding orifice (32) on the other blade. The protruding coupling element (31) is housed in the orifice (32) when the blades (2) are in the joined position. In some embodiments, it is press-fitted and / or clipped in. In other embodiments, the protruding element (31) is clamped in place. Preferably, the couplers (31, 32) are configured to be coupled outside the support surface formed by the joined blades (2).

[0076] Advantageously, this allows the operator to perform the coupling without being hindered by the person, and without having to manipulate them.

[0077] In some embodiments, each blade (2) further includes gripping means (7) on at least a portion of an edge (23) of the blade (2) forming a lateral edge (230) of the support surface (S). This provides additional gripping means and simplifies the gripping and lifting of the device.

[0078] In embodiments, the gripping means (7) of the lateral edges (230) of the support surface (S) have openings, preferably specific (11), suitable for receiving means for immobilizing a part of the person, for example straps for fixing a part of the person's body, and / or an immobilizer for a part of a person's body, for example a head immobilizer.

[0079] Advantageously, in the case where the two blades (2) are symmetrical, identical openings are present at the level of an area intended to accommodate the person's feet.

[0080] These restraint means allow the person's body to be immobilized, reducing the risk of their condition worsening. Thus, restraint straps can be used to immobilize the person at the thorax, pelvis, and lower limbs, these straps passing through the openings of the grasping means (7). The restraint means can also be used to secure an immobilizer, for example, a head immobilizer. In other embodiments, the head immobilizer itself consists of straps. In other preferred embodiments, the immobilizer comprises a head cushion, fixed to the surface, and possibly two lateral immobilization blocks, and at least two head restraint straps at the forehead and chin. Advantageously, the restraint means can also be used to stiffen and reinforce the assembly of the two blades (2).

[0081] In some embodiments, the blades (2) share a point of symmetry when assembled, the point of symmetry being at the center of the longitudinal midline of the assembly formed by the two blades (2).

[0082] Advantageously, this allows for intuitive assembly, without needing to consider the potential orientation of the blades (2), which is important in rescue situations, which are often emergencies requiring rapid action. Furthermore, it simplifies the manufacturing of the blades (2), as a single mold type is sufficient to produce both blades (2) of the device.

[0083] Preferably, the grasping means (5) are also identical on each side of the blades (2).

[0084] In some embodiments, the grasping means (5) form U shapes, each end of which connects a longitudinal end of a blade (2), in order to connect and lock together the two longitudinal ends of two different blades (2).

[0085] In certain embodiments, as illustrated by way of example and without limitation to the Figures 5A and 5B , the device further includes stiffening means (8), preferably stringers, preferably still carbon reinforcement tubes, which extend longitudinally in each of the blades (2) of the device.

[0086] In some embodiments, the stiffening means (8) extending longitudinally in each of the blades (2) of the device are fixed and radio-transparent, which makes it possible not to interfere with the passage in radiology.

[0087] The stiffening means (8) can be made of carbon fiber, or any other material strong enough to allow the stiffening of the blades (2) while preferably being radio-transparent.

[0088] The blades (2) may include other stiffening means (81), for example, stiffening means (81) for the gripping areas on the periphery of the surface S, as illustrated by way of example and without limitation in the figure 2A And 5B These additional stiffening means (81), also called stiffening inserts (81), can be formed from different materials as required. Preferably, they are made of PEEK (a heat-resistant plastic, polyetheretherketone). In some embodiments, they can also be used to fix and hold in place the stiffening means, for example, stringers (8).

[0089] The projecting members forming rods (51) on which the locking latches (52) of the ends (50) of the gripping means (5) will be fixed can be overmolded into each blade, as illustrated by way of example in the figure 5A Preferably, said protruding parts (51) are not removable.

[0090] It is easily understood that a latch (52) and a protrusion member (51) can be substituted for one another. In other words, in some embodiments, the latch (52) can be present on the blade while the complementary protrusion member (51) can be present at the end (50) of the grasping means (5).

[0091] In certain situations, it may be useful to be able to increase the support surface for a person, for example when they are particularly tall.

[0092] In some embodiments, the gripping means (5) further include an additional support surface (10) to increase the support surface (S) on which a person can be carried, for example, by forming a footrest or a headrest. This additional support surface (10) may or may not be removable from the gripping means (5). In embodiments where the additional support surface (10) is removable, it may be coupled to the gripping means (5) by being press-fitted, clipped, or screwed, for example, to the parts of the gripping means (5) parallel to the lateral edges of the blades (2), or to the ends of the gripping means (5) opposite those that are locked onto the blades.

[0093] In some embodiments, the additional support surface (10) includes a gripping area formed by a recess or indentation.

[0094] It is possible to add a means of stiffening the additional support surface (10). This stiffening means (not shown) could, for example, be a rigid U-shaped bar fixed parallel to the lateral edges of the blades (2) and to the gripping means (5) comprising the additional support surface (10). This fixing could be achieved by force-fitting, clipping, or securing with fasteners such as screws. The fixing could, for example, be achieved by clipping with a pivoting motion.

[0095] It may also be useful to add an additional piece forming an additional support surface (10) on one of the central ends of the surface (S). This piece can be held in place by straps, as with a head immobilizer, or by a Velcro-type fastening means (registered trademark), a Velcro area being, for example, attached to a part of the surface (S) by straps, and the additional piece comprising a Velcro area capable of attaching to the Velcro area of ​​the surface (S).

[0096] In some embodiments, the grasping means (5) include openings configured to accommodate additional grasping means (5), grasping means (5) comprising an additional support surface (10), or another part forming an additional support surface (10). The additional grasping means (5) may themselves include openings configured to accommodate other grasping means (5). Advantageously, this allows the support surface to be increased virtually at will, as additional stiffening means can also be added to a portion of the grasping means to stiffen the assembly. The grasping means can be attached by clipping, or by a pressure ball similar to the system for adjusting the length of crutches.In another embodiment, the fastening and locking system is similar to that used to lock the grasping means (5) to the ends of the blades (2), as illustrated by way of example and without limitation in the . figure 5 .

[0097] The additional support surface (10) can be formed from a single piece, or from several parts, preferably two, particularly to form a footrest. In the case of a surface in two parts, they can be independent of each other and fixed to each arm of the gripping means (5) forming a hoop.

[0098] A person skilled in the art will readily understand that the additional part may include grasping means, which may extend beyond the support surface S.

[0099] In some embodiments, the additional support surface (10) can be formed from an area providing additional support (10) and two parallel, corrugated arms configured to be attached to the longitudinal ends of the blades by passing over the gripping means and under the blade ends. This has the advantage of improving the mechanical strength of the part through a lever effect.

[0100] In certain embodiments, as illustrated in a non-limiting manner in figures 7A-7GThe additional support surface (10) is removably attached to the grasping means (5) of the blade assembly position (2). This additional support surface (10), also referred to as the extension, comprises at least one attachment system for the grasping means (5) of the blade assembly position (2). The extension may thus include a hollow portion whose shape is complementary to that of the grasping means (5), as illustrated, without limitation, in the figure 7B-7C . The fixing can be achieved by fitting it onto one of the graspable means (5) forming hoops to obtain very good mechanical hold.

[0101] In certain embodiments, in which the graspable means (5) comprise a graspable projecting portion having a recess, a latch (101) can be inserted into said recess, as illustrated in the figure 7D, to block and fix the additional support surface (10) onto the grasping means (5), for example, but not limited to, fixing the joint. In some embodiments, the lock has parallel arms and is configured to lock the extension (10) onto the grasping means (5) by rotating said lock (101) from an unlocked position ( figure 7E ) in a locking position of the extension cord, as illustrated in the figure 7F said arms being then locked in translation between a locking plate (102) and the extension (10), as illustrated in the figure 7G .

[0102] In some embodiments, the assembled lock (101) has a greater thickness than the extension (10). This allows for easier handling of the lock.

[0103] In some embodiments, at least the blades (2) are X-ray transparent. In certain embodiments, the blades (2) and the stiffening means (81) are X-ray transparent. This advantageously allows for an X-ray of the person to be taken without having to remove the device (1) on which it rests.

[0104] The materials used to make the device must also be water-resistant, non-oxidizing, and easily cleanable to prevent soiling or contamination. Indeed, the device must not be able to absorb biological fluids or blood to avoid the transmission of infectious germs.

[0105] In some embodiments, the assembly process for a person transport device (1) as described above comprises the following steps: Place successively each of the first and second blades (2) on either side of the person lying on the ground, Secure at least one of the grasping means (5), preferably one of the ends (50) of one of the grasping means (5), to one of the longitudinal ends (210) of the surface, preferably one of the longitudinal ends (21) of a first blade, by a first coupling point, then secure said grasping means (5), preferably the other end (50) of the grasping means (5), to a second coupling point of the end (210), preferably to the coupling point of the longitudinal end (21) of the second blade (2) to assemble the two blades (2), the joining being carried out by a pivoting movement, Repeat the previous operation with the other longitudinal end (210) of the surface (S) to be formed, preferably the other opposite longitudinal ends (21) of the two blades (2),to assemble the two blades (2) under the person in the assembly position, by a pivoting movement, to form a support surface (S) under said person. Lift the device (1) to transport the person.

[0106] It is thus sufficient to couple one end of a gripping means to one end of a first blade, then to connect said gripping means to the end of a second blade, by a pivoting movement.

[0107] There figure 6 illustrates, for example and in a non-limiting manner, one possible method for assembling the device for lifting and transporting a person (20). The blades (2) are initially separated ( Fig. 6A). The two blades (2) can be joined at one of their ends, for example forming the part intended to receive a person's head, by means of a grasping means (5). The grasping means (5) is coupled, preferably by a first end (50), to an end (21) of a blade (2) ( Fig. 6B ). By a pivoting movement, the grasping means (5) is brought into contact and coupled to a second end of a blade (2) to join the two blades (2) to form one end of the surface (210) ( Fig. 6C ). The same operation is repeated at the opposite ends (21), for example forming the part intended to receive a person's feet, ( Fig. 6D and 6 E< ) in order to assemble the blades in the assembly position. It is also possible to first couple the two blades (2) forming the surface (S) of the device, then to assemble the gripping means (5) to the ends (21) of the blades (2).

[0108] In some embodiments, each coupling point includes a pivot point. Thus, in some embodiments, as illustrated in the figure 6 The device (1) includes a coupling (3) comprising two coupling points at each longitudinal end (210) of the surface (S), preferably one at each longitudinal end (21) of each blade (2), each coupling point having a pivot point. Thus, the gripping means (5) can be fixed at one longitudinal end (21) of any blade, and then fixed at a second longitudinal end (21) by a pivoting movement.

[0109] The gripping mechanism can be made of wood, metal, carbon fiber, or another lightweight and rigid material. Preferably, it is made of aluminum and forms a hollow bar, ideally incorporating reinforcing ribs. The locking mechanism can be made of metal, preferably aluminum and stainless steel.
