Description

TITLE: DEVICE FOR LIFTING AND TRANSPORTING A PERSON

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates generally to the field of lifting devices for an individual, in particular the field of stretchers and stretchers in two parts.

STATE OF THE PRIOR ART

[0002] In an accident or a fall, it is possible that the victim is on the ground and likely to have a trauma preventing him from getting up. In some cases, it is therefore advisable that the victim moves as little as possible, so as not to modify the arrangement of his spine, so as not to damage or potentially worsen his situation. Thus, rescuers, once at the scene of the accident, must carefully lift the victim to the ground in order to transport him so that he can be taken care of. The use of a stretcher reduces the risks when handling the victim.

To limit the risk of aggravation of a possible fracture, or even of a potential lesion of the spinal cord during the mobilization or transport of the victim, it may be advantageous to immobilize the whole body (and the head) of said victim on the stretcher. Thus, the manipulation of the person must be carried out in accordance with the regulations, that is to say without moving his cervical and spinal column, commonly called in relief, the head-neck-trunk axis.

[0004] Finally, it is common for the person, the victim, or the patient, to perform a radiology visit in order to determine the potential fractures and lesions. It may be necessary to make this passage quickly and before moving the patient from the stretcher to another support, which is why it is strongly recommended that the stretchers be made of radiolucent material.

[0005] In the prior art, the use of a hard surface is proposed on which the victim or the patient is placed in a lying position. Straps allow immobilize the victim's body on the hard plane, and an optional head immobilizer can be used to immobilize the head.

The hard plan is made up of:

- Rectangular, similar in size to a person, made of PVC, if possible radiolucent, water resistant, and biologically inert (absorption of biological fluid or blood by the material must not be possible to prevent the transmission of infectious germs). This hard top is equipped with carrying handles;

- Retaining straps to immobilize the victim in the thorax, pelvis and lower limbs.

The head immobilizer is composed of:

- A head cushion, fixed on the hard surface;

- Two lateral immobilization blocks;

- Two head support straps at the forehead and chin.

[0006] One of the drawbacks of this solution is that it poses risks when handling the victim to place him on his back lying on the hard surface. Indeed, it is necessary to lift or roll the victim to place him on the hard plane. During this manipulation, the risk of moving the cervical and spine of the victim is particularly present which can lead to worsening of his health. Particularly, when the victim to be lifted is in a narrow space, the manipulation is then more complex and sometimes difficult to carry out in order to place the victim on the hard plane without risking harm to his health.

[0007] Another solution is to use the spoon stretcher, which is a product in two separable parts. The two parts, once assembled, form a system on which it is possible to deposit and transport a victim. The advantage of this solution lies in the possibility of inserting on each side under the victim or the patient, one of the two parts of the stretcher so as to secure the two parts when they are already under the patient. This makes it possible to reduce risky manipulations carried out on said patient. The use of such a device is particularly indicated in the following cases

- Victim traumatized and suspected of trauma to the spine to install it on a vacuum immobilizer mattress; - Impossibility of creating a simple bridge or an improved bridge (low area, for example the person is under a train, a vehicle ...). This device must also make it possible to raise a victim without traumatic injury, and without presenting soiling or soiling (the equipment must be non-oxidizable and easily cleanable). This type of stretcher simplifies the insertion of the stretcher in two parts under the person, but the parts are sometimes complex to join together in a solid and durable way. However, the gripping of such a stretcher can also be made more complex, in order not to separate the two parts. Finally, the spoon stretcher does not make it possible to immobilize a victim, unlike a hard plane or a vacuum mattress. It is just used to raise and then transport a victim to a hard plane or a vacuum mattress.

[0008] Patent WO1998037848 presents a patient transport support based on a spoon stretcher and consists of separable halves, in order to facilitate their positioning under the patient's body. It is designed to allow an X-ray examination to be performed. The existing junction area between the halves and the points where the pivot and locking mechanisms are located are offset laterally from the centerline or longitudinal centerline of the patient support when assembled.

[0009] One of the drawbacks of this device is that the central part, when lifting, is too thick to prevent rescuers from moving the victim. The offset hinges impose a thickness high enough to meet the weight constraints increased by the deportation of the hinges. In addition, said hinges and their matching system involve a transverse assembly of the product, which is liable to pinch the person raised and / or to manipulate him too much during. Indeed this assembly requires that the victim is moved at the height of the cervical, which involves risks for the spine. This manipulation is also contrary to the regulations in terms of rescue actions. Finally, the fixing means are close to the patient's head and feet, which can be inconvenient both during the assembly of the two parts, but also during transport. These fasteners are generally made of metal, or reinforced with metal, not radiolucent for reasons of durability, which can cause discomfort during an X-ray. Another simple spoon-type stretcher device is proposed by patent GB2502830, the device having two blades having a form cooperation at their longitudinal ends in order to be secured and held by removable straps at the level of the end close to the patient's head. Once the straps are fixed, their tightening allows them to be entered into a recess so as not to hamper the operator. The operation can be complicated depending on the congestion around the patient and the level of urgency of the situation. Indeed, once the blades are secured, it is necessary to pass the straps, then loose, in the head structure in order to lock the securing of the blades, which can be complex and require dexterity, in addition to being against intuitive and long, especially in emergency situations. The stretcher is conventionally gripped by the sides, which presents a drawback in cramped situations. Indeed, with this type of stretcher, you must both have access to the longitudinal ends in order to assemble the two parts of the stretcher, and pass the straps through said ends, and also have access to the sides of the stretcher, there where the gripping means are located, in order to lift and transport the person.

Finally, the device described in patent US Pat. No. 5,803,087 comprises two separable blades without cooperation of form, which are secured to each other by non-removable linear bars (taken in the mass of the blades), the bars having a central locking means allowing to lock them together. These non-removable bars are likely to interfere with an x-ray of the patient. In addition, the blades are flat and meet over their entire length, which can cause problems in placing each of the blades on either side of the patient without too much handling the patient and without moving its head-neck-trunk axis. Finally, the gripping of the device is performed on the bars or the sides of the blades, and can therefore be complex once the person has been placed on the blade assembly, particularly in a cramped environment.

[0012] This results in a need for a device for lifting, transporting and immobilizing a person which is easily manipulated regardless of the environment in which it is used, and whose use is easy and n ' does not cause risks to the health of the patient when handling it, and offering a solid and durable assembly, without the device representing a discomfort during an x-ray.

Many combinations can be envisaged without departing from the scope of the invention; those skilled in the art will choose one or the other depending on the economic, ergonomic, dimensional or other constraints that they will have to comply with.

[0038] In general, the present invention relates to a device (1) for transporting a person comprising a support surface (S) extending longitudinally, preferably concave, 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 gripping means (5) of the device (1), the gripping means being removable with respect to said device, the device further having at least one coupling between each of the gripping means (5) and each of the longitudinal ends (210),

the device (1) being characterized in that the coupling comprises at least two coupling points including at least one pivot.

Preferably, the coupling is so configured that each gripping means can be coupled by a pivotal movement from a first coupling point to the second coupling point.

It is important to note that such a transport device can both be used by rescuers as a stretcher having a function of lifting and transporting a person, and as a hard plane having a function of immobilizer of the person. In other words, the person can remain on the device during their transport to the hospital, for example by ambulance, without the need to transfer them to another means such as a hard plane or an immobilizing mattress. depression.

[0041] The removable coupling allows for less space both during transport and during placement of the device under the patient.

[0042] In certain embodiments, said coupling of the gripping means with the longitudinal ends (210) of the surface further comprising locking means (51) capable of locking said gripping means at said coupling points of said ends (210).

[0043] This advantageously makes it possible to lock the gripping means regardless of the direction of gripping and the force applied. Preferably, the locking means comprise a clip, a latch or any other means enabling the gripping means to be reversibly locked, regardless of the direction of the force applied to said gripping means.

In some embodiments, the gripping means (5) have a length less than 50%, preferably 25% of the length of the support surface (S). This makes it possible to reduce the size of the device, particularly during assembly of the device, but also during transport of the device, particularly before assembly.

In some embodiments, the gripping means (5) do not extend into the support surface (S) over a length greater than 50%, preferably 25% of the length of said surface (S) of support. This advantageously makes it possible to reduce the size of the device, particularly during assembly of the device.

In some embodiments, each of the gripping means (5) forms a gripping protruding portion, and extends beyond the support surface (S). This advantageously makes it possible to provide an additional gripping zone offset with respect to the support surface (S) and to the person, which can improve and simplify the handling of the person in confined spaces. In some embodiments, the gripping protruding portion (5) extends substantially in the same plane as the support surface (S). In other embodiments, the gripping protrusion extends into another plane, which in some situations allows for easier gripping.

Preferably, the gripping means (5) of the device (1) are rigid, which makes it possible to facilitate their gripping and their coupling to the longitudinal ends (210) of the surface (S) by means of a pivot. In some embodiments, the pivot comprises an axis of rotation substantially perpendicular to the plane of the surface (S).

By substantially is meant approximately perpendicular. In all cases, the pivot always has an axis of rotation perpendicular to the coupling plane.

In some embodiments, the device (1) comprises at least two blades (2) extending along an axis (L) mainly longitudinal between two ends and each comprising two edges (22, 23), and two ends longitudinal (21),

the blades (2) being configured to be assembled to one another in a reversible manner 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 gripping means (5) and each longitudinal end (210) of the surface being produced at the level of the ends (21) of each blade (2).

The longitudinal axis "L" crosses the surface formed by the two blades at its longitudinal center line.

Advantageously, the presence of two separable blades, or spars, makes it possible to raise the person in accordance with the regulations, that is to say without moving his cervical and his spine, commonly called emergency, the head axis. neck-trunk.

It is thus sufficient to couple a first 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 pivot movement .

In some embodiments, the gripping means (5) form assembly means of said assembly position of the blades, the coupling of the gripping means with the longitudinal ends (210) of the surface comprises locking means capable of being locked at said ends (21, 210) of the two blades (2).

The device thus advantageously allows a locking means which makes it possible to be coupled to the ends of a surface formed by two blades to thus both allow i) its assembly, ii) its gripping, and iii) the locking of the coupling and therefore assembly. This thus allows a robust assembly in several stages, which thus makes it possible to pre-assemble the device by a first coupling (3) between each of the blades, then a final assembly by the coupling of the locking means at the ends of said blades in order to stiffen and make safer said assembly. The final assembly can then be lifted by said locking means. Thus, in an environment with a lot of space, the fact of being able to assemble the blades first by a first coupling, then the means for gripping the blades by a second coupling allows simplification of use, a characteristic often relevant in urgent situations, which is often the case when using a device of this type. It is also easier and faster to complete assembly, when the device has been assembled directly under the patient to be transported.

In some embodiments, the gripping means (5) have a length less than 25% of the length of the support surface (S). This makes it possible to reduce the size of the device, particularly during assembly of the device, but also during transport of the device, particularly before assembly.

In some embodiments, the gripping means (5) do not extend into the support surface (S) over a length greater than 25% of the length of said support surface (S). This advantageously makes it possible to reduce the size of the device, particularly during assembly of the device.

In some embodiments, the device (1) comprises, in the assembly position, a space between said surface and each of the gripping means, in particular by a notch on each of the blades near the points where said gripping means (5) are made integral with the ends (21) of the blades (2).

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 plane (X) of support, the longitudinal axis (L ) being a line contained in the plane (X).

[0060] Preferably, the gripping protruding portion can be gripped regardless of the direction of gripping. This is facilitated when the gripping protruding portion has a recess. This advantageously makes it possible to simplify the gripping of the device (1), regardless of the space around it (in a damaged car, under a train or under debris, etc.)

[0061] The term “support surface” is understood to mean a surface whose size and shape are at least able to support the body of a person.

[0062] The attachment of the gripping means to the longitudinal ends (210) of the support surface allows the grip to be removed from the body of the person. Since the coupling is reversible, the gripping means can be made of non-radio transparent metal, and be removed before going into radiography, thus making the slide assembly on which the person is lying radio compatible.

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. Thus, this allows the operator to visually confirm the correct coupling of the blades. This avoids having to perform complex manipulation of the person and the blades to form the support surface, and furthermore not to perform this blindly.

In addition, the deportation of the gripping means (5) makes it possible not to have to perform a complex manipulation of the person and the blades to assemble and carry said blades (2), the coupling of the gripping means (5) with said blades (2) then representing no risk for the person. In this way, the operator, usually a rescuer, has a visual of the entire operation, without never work blind, which further reduces the risk of the person's situation worsening.

In some embodiments, the surface formed by the assembly of the two blades comprises an orifice (4) which extends along the longitudinal axis (L) on at least part of said surface (S) .

Advantageously, this makes it possible to place the blades more easily on each side and to assemble them without risking pinching the person's body. It also allows a visual examination of the back of the person, at the level of the orifice once it is placed on the device (1) and raised. The term “orifice” is understood to mean any open area or open surface which may have different shapes. Thus the orifice may have a circular, oblong, rectangular or any other shape which makes it possible to improve the visual examination of the person without risking to pinch it during the assembly of the blades, and while maintaining good resistance to stress constraints due to the person's weight.

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.

In embodiments, as for example illustrated in a non-limiting manner in FIG. 1, the assembly of the two blades (2) of the device (1) by couplers (31, 32, FIG. 2A and 3) form a stretcher device (1) comprising a support surface (S) on which a person can be lying. Operators can lift and carry the device (1) by the gripping means (7) formed by openings along the side edges (230) of the surface (S) of said device, or by the gripping means (5) arranged at each end of the device.

[0069] In some embodiments, the surface is slightly concave in order to improve the comfort of the person. In some combinable and non-limiting embodiments, the inclination of the concave surface is low at the location of the person's head in order to improve comfort. In certain embodiments, the device has a length measuring between approximately 175cm and 220cm, preferably between approximately 185 and 195 cm, and a width measuring between approximately 40 and 60 cm, preferably between 45 and 55 cm.

Thus, the blades (2) each comprise at least a central longitudinal edge (22) and a lateral longitudinal edge (23), the coupling (3) being produced at the level of the central longitudinal edges (22), and the edges lateral longitudinal edges (23), free, forming the lateral longitudinal edges (230) of the surface (S).

In embodiments, each blade (2) comprises at each of its two longitudinal ends (21) a projecting member (51), and each gripping means (5) comprises two ends (50), each of the ends (50) being complementary to one of said protruding members (51), and able to be made integral and locked on one of said protruding members (51) by a locking means (52).

Doubling the securing and locking means thereof, and deporting them both makes it possible to stiffen the assembly without the slats having a very large thickness.

[0074] More particularly, FIG. 2A illustrates an exemplary non-limiting embodiment of the present invention, in which a locking means (5), forming an arch, locks the assembly of the two blades (2). The arch (5) comprises an end (50) forming an arm and is locked on a projecting member (51) of the blade (2) by means of a latch (52) which clamps said projecting member (51).

In embodiments, as for example illustrated in a non-limiting manner in Figures 2A, 2B and 3, the device further comprises an additional fixing means (9) of the gripping means (5), for example an alcove or a recess present at each longitudinal end of the support surface (210), on the edge of the device, the gripping means (5) being configured to be forced into said additional fixing means (9). Preferably each blade (2) comprises an additional fixing means (9). This makes it possible to stiffen the assembly of the blades (2) with the gripping means, in addition to the locking of the gripping means on said blades (2). Advantageously, this also makes it possible to distribute the force stresses over the entire periphery of the longitudinal ends (21) of the blades (2) rather than concentrating it on the gripping points.

As shown in Figure 3, it is possible to force the gripping means (5) into the additional fixing means (9), by pivoting it after having locked it on one side on a protruding member (51) of a blade (2), the projecting member (51) then representing the pivot point. The fixing means (9) thus allows the device (1) to have an additional fixing in addition to the projecting members (51) complementary to the locking means (52).

In certain embodiments, as for example illustrated in a nonlimiting manner in FIGS. 4A and 4B, the gripping means (5) forming a gripping protruding portion can be produced by molding in which an optimized network of ribs (54) is produced. to improve resistance to stress without significantly increasing weight. The gripping means (5) can be formed from two independently molded parts.

In some embodiments, as for example illustrated in a non-limiting manner in FIG. 4C, each of the ends (50) of the gripping means (5) comprises an arm comprising at least one locking latch (52), complementary to one of said projecting members (51), the latch (52) being movable between a closed position, called rest, 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 an element for returning the latch (52) to the closed position, for example a spring. This allows the operator, for example a rescuer, to easily and durably lock and unlock the locking means (52) during assembly. Preferably, the locking means comprises a locking indicator, for example a visual indicator or an audible indicator. Preferably, the locking means (52) comprises an audible indicator such as a locking pawl capable of emitting a sound when it is locked, for example by clipping. [0080] In preferred embodiments, the protruding members (51) and the locking means (52) are configured to be coupled and locked with each other outside the support surface formed by assembly of the blades (2). This advantageously allows the operator to perform the coupling without being hampered by the person, and without having to handle it.

In embodiments, as for example illustrated in a non-limiting manner in Figures 2A and 3, each blade (2) comprises a coupling (3), preferably at each longitudinal end of the blade (21), each coupling ( 3) being formed of a coupler of a complementary blade of a coupler of the other blade in order to allow the assembly of the two blades (2), the complementary couplers (31, 32) preferably forming a pair formed of a projecting coupling member (31) present on a blade, complementary to an orifice (32) present opposite the other blade, the projecting coupling member (31) being housed in the orifice (32) when the blades (2) are in the assembly position. In some embodiments, it is entered by force and / or by clipping. In other embodiments, the protruding member (31) is made by clamping. Preferably, the couplers (31, 32) are configured to be coupled to the outside of the support surface formed by the assembly of the blades (2).

Advantageously, this allows the operator to perform the coupling without being inconvenienced by the person, and without having to handle it.

In embodiments, each blade (2) further comprises gripping means (7) on at least part of an edge (23) of the blade (2) forming a lateral edge (230) of the support surface (S). This allows for additional gripping means, and simplifies gripping and lifting of the device.

In embodiments, the gripping means (7) of the lateral edges (230) of the support surface (S) have orifices, preferably specific (1 1), capable of accommodating immobilization means d a part of the person, for example straps for fixing a part of the body of the person, and / or an immobilizer of a part of the body of a person, for example a head immobilizer. Advantageously, in the case where the two blades (2) are symmetrical, identical orifices are present at a zone intended to accommodate the feet of the person.

[0086] These fasteners make it possible to immobilize the person's body, reducing the risk of worsening their health. Thus, retaining straps can be used to immobilize the person at the level of the thorax of the pelvis and of the lower limbs, said straps passing through the openings of the gripping means (7). The fixing means can also make it possible to fix an immobilizer, for example a head immobilizer. In other embodiments the head immobilizer itself consists of straps. In other preferred embodiments, the immobilizer is composed of a head pad, fixed to the surface, and possibly two lateral immobilization blocks, and at least 2 straps for maintaining the head at the level. forehead and chin. Advantageously, the fastening means can also make it possible to stiffen and solidify the assembly of the two blades (2).

In some embodiments, the blades (2) share a point of symmetry when they are assembled, the point of symmetry being at the level of the center of the longitudinal center line of the assembly formed by the two blades (2) .

Advantageously, this makes it possible to provide an intuitive assembly, without needing to take into account a potential direction of the blades (2), which is important in emergency situations, which are often emergency situations in which we have to act quickly. In addition, this allows simplified manufacture of the blades (2), a single type of mold being sufficient to manufacture the two blades (2) of the device.

Preferably, the gripping means (5) are also identical on each side of the blades (2).

In some embodiments, the gripping means (5) form Us, 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) . In certain embodiments, as illustrated by way of example and in a nonlimiting manner in FIGS. 5A and 5B, the device further comprises stiffening means (8), preferably side members, more preferably still carbon reinforcement tubes, which extend longitudinally in each of the blades (2) of the device.

In some embodiments, the stiffening means (8) extending longitudinally in each of the blades (2) of the device are immovable and radiolucent, which makes it possible not to hinder the passage in radiology.

The stiffening means (8) can be made of carbon fiber, or any other material strong enough to stiffen the blades (2) while being preferably radiolucent.

The blades (2) can include other stiffening means (81), for example stiffening means (81) of the gripping zones on the periphery of the surface S, as illustrated by way of example and in a nonlimiting manner in FIGS. 2A and 5B. These additional stiffening means (81), also called stiffening inserts (81) can be formed in different materials as required. Preferably, they are made of PEEK (thermostable plastic, polyetheretherketone). In certain embodiments, they can also make it possible to fix and hold in place the stiffening means, for example side members (8).

The protrusion members forming rods (51) on which the locking latches (52) of the ends (50) of the gripping means (5) can be molded into each blade, as illustrated by way of example in figure 5A. Preferably, said projection members (51) are not removable.

It is easily understood that a latch (52) and a projection member (51) can be substituted for one another. In other words, in some embodiments, the latch (52) may be present on the blade while the complementary protrusion member (51) may be present at the end (50) of the gripping means (5). . In certain situations, it may be advantageous to be able to increase the support surface of a person, for example when the latter is particularly large.

In some embodiments, the gripping means (5) further comprise an additional support surface (10), to increase the support surface (S) on which a person can be transported, for example by forming a rest foot or headrest. This additional support surface (10) may or may not be removable with respect to said gripping means (5). In the embodiments where the additional support surface (10) is removable, it can be coupled to the gripping means (5) by being force-in, clipped or even screwed, for example to the parts of the gripping means (5) parallel to the lateral edges of the blades (2), or at the ends of the gripping means (5) opposite to those which are locked on the blades.

In some embodiments, the additional support surface (10) comprises a gripping area formed by a recess or a recess.

It is possible to add a means of stiffening the additional support surface (10). This stiffening means (not shown) can for example be a rigid U-bar fixed parallel to the side edges of the blades (2) and to the gripping means (5) comprising the additional support surface (10). This fixing can be produced by being force-fed, clipped or else fixed by fixing means such as screws. The fixing can for example be carried out by clipping by a pivot movement.

[00101] It may also be advantageous to add an additional part forming an additional support surface (10) on one of the central ends of the surface (S). This part can be kept fixed by straps, as for a head immobilizer, or by a Velcro type attachment 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 suitable for hooking to the velcro area of the surface (S). [00102] In some embodiments, the gripping means (5) comprise orifices configured to accommodate additional gripping means (5), gripping means (5) comprising an additional support surface (10), or another part forming additional support surface (10). The additional gripping means (5) can themselves comprise orifices configured to accommodate other gripping means (5). Advantageously, this makes it possible to virtually increase the support surface at will, additional stiffening means possibly being added to part of the gripping means in order to stiffen the whole. The fixing of the gripping means can be achieved by clipping, by a pressure ball like the system for adjusting the length of the crutches. In another embodiment, the fixing and locking system is similar to that used to lock the gripping means (5) at the ends of the blades (2), as illustrated by way of example and not limited to figure 5.

[00103] The additional support surface (10) can be formed as a single piece, or in several parts, preferably two, particularly to form a footrest. In the case of a surface in two parts, they can be independent of one another, and fixed on each branch of the gripping means (5) forming an arch.

[00104] Those skilled in the art will easily understand that the additional part can include gripping means, which can extend beyond the support surface S.

[00105] In some embodiments, the additional support surface part (10) may be formed of an additional support surface area (10), and two parallel and wavy branches so that they are configured to be attached to the longitudinal ends of the slats by passing over the gripping means and below the ends of the slats. This has the advantage of improving the mechanical strength of the part thanks to a leverage effect.

[00106] In certain embodiments, as illustrated in a non-limiting manner in Figures 7A-7G, the additional support surface (10) is fixed from removable manner on said gripping means (5) from said assembly position of the blades (2). Said additional support surface (10), also called an extension, comprises at least one system for fixing to the gripping means (5) of said assembly position of the blades (2). The extension can thus comprise a recessed part, the shape of which is complementary to that of the gripping means (5), as illustrated in a non-limiting manner in FIG. 7B-7C. The fixing can be carried out by fitting onto one of the gripping means (5) forming hoops to obtain very good mechanical strength.

In certain embodiments, in which the gripping means (5) comprise a gripping protruding portion having a recess, a latch (101) can be introduced into said recess, as illustrated in FIG. 7D, to block and fixing the additional support surface (10) on the gripping means (5), for example in a non-limiting manner, to fix the socket. In some embodiments the lock has parallel arms and is configured to lock the extension (10) on the gripping means (5) by rotating said lock (101) from an unlocked position (Figure 7E) into a locked position. of the extension, as illustrated in FIG. 7F, said arms then being blocked in translation between a plate for locking (102) and the extension (10), as illustrated in FIG. 7G.

[00108] In some embodiments, the assembled latch (101) has a thickness greater than the thickness of the extension (10). This allows easier manipulation of the lock.

[00109] In some embodiments, at least the blades (2) are transparent to X-rays. In some embodiments, the blades (2) and the stiffening means (81) are transparent to X-rays. This advantageously allows to make it possible to take an x-ray of the person without having to remove the device (1) on which it rests.

[00110] The materials which make up the device must also be resistant to water, non-oxidizable and easily cleanable, so as not to present any soiling or soiling. In fact, the absorption of biological fluid or blood by the material must not be possible in order to avoid the transmission of infectious germs. In certain embodiments, the method of assembling a device (1) for transporting a person as described above, comprises the following steps:

- Place successively each of the first and second slats (2) on each side of the person lying on the ground,

- Make at least one of the gripping means (5), preferably one of the ends (50) of one of the gripping means (5) (5), integral with 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 attach said gripping means (5), preferably the other end (50) of the gripping means (5), to a second coupling point of the end (210), preferably at the coupling point of the longitudinal end (21) of the second blade (2) to assemble the two blades (2), the connection being made by a pivot 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), in order to assemble the two blades (2) under the person in the assembly position, by a pivotal movement, to form a support surface (S) under said person.

- Lift the device (1) to transport the person.

[00112] It is thus sufficient to couple a first 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 pivot movement .

[00113] FIG. 6 illustrates, for example and in a non-limiting manner, a possible method for assembling the device for lifting and transporting a person (20). The blades (2) are first separated (Fig. 6A). The two blades (2) can be assembled at one of their ends, for example forming the part intended to receive the head of a person, thanks to a gripping means (5). The gripping means (5) is coupled, preferably by a first end (50), to one end (21) of a blade (2) (Fig. 6B). By a pivotal movement, the gripping means (5) is brought into contact and is coupled to a second end of a blade (2) to secure the two blades (2) in order to forming 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 the feet of a person, (Fig. 6D and 6 ^E ) in order to assemble the blades in the assembly position. It is also possible to firstly 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).

[00114] In certain embodiments, each of the coupling points comprises a pivot point. Thus in certain embodiments as illustrated in FIG. 6, the device (1) comprises a coupling (3) which comprises two coupling points at each longitudinal end (210) of the surface (S), preferably one to each longitudinal end (21) of each blade (2), each of the coupling points having a pivot point. Thus, the gripping means (5) can be fixed at a longitudinal end (21) of any blade, then can be fixed at a second longitudinal end (21) by a pivot movement.

[00115] The gripping means can be made of wood, metal, carbon fiber or another light and rigid material. Preferably, it is made of aluminum and forms a hollow bar, which preferably comprises reinforcing ribs. The lock can be made of metal, preferably aluminum and stainless steel.

The following table shows the possibilities of manufacturing the various elements constituting the device. Each characteristic detailed in this table can be taken independently of the other characteristics listed, and those skilled in the art will thus understand that each characteristic can be combined without limitation with another, present in the table or described above. [00117] [Table 1]

[00118] Asperities or cavities can be added at the level of the grip zones in order to improve the grip. These asperities or cavities can be made from the same material, or from another material, for example non-slip such as rubber. Those skilled in the art will easily understand on reading the present application that the term "longitudinal ends" of the blades (2) includes areas at the end of the blades (2) which may include several different elements, such as for example a coupler (3), a projecting member (51) on which a hoop (5) can be locked, and an additional fixing means (9), said different elements possibly being distinct, and preferably being so. However, those skilled in the art will easily understand that in certain cases, the same element can fulfill several characteristics described above.

It will easily be understood on reading the present application that the features of the present invention, as generally described and illustrated in the figures, can be arranged and designed according to a wide variety of different configurations. Thus, the description of the present invention and the related figures are not intended to limit the scope of the invention but simply represent selected embodiments.
