Description

Title of the invention: Manual transfer harness for people with reduced mobility. Technical field

[0001] The present invention relates to a manual transfer harness for persons with reduced mobility. Such a harness can be used in hospitals, medical-social establishments, at home, in transport, etc. Technical background

[0002] It is known to carry out the handling of a person with reduced mobility using a person lift comprising a transfer harness and an electric mechanical lift system.

[0003] There are different types of patient lifts such as: multi-function patient lifts, mobile patient lifts that can be moved freely on the floor, ceiling-mounted patient lifts, patient lifts with a weighing system, wall-mounted patient lifts, verticalization and / or lifting aids, bath and / or pool patient lifts, boat transfer patient lifts, etc.

[0004] The electrical system allows the person to be moved horizontally and vertically for transfer without significant physical effort for the caregivers or those around the person and under optimal conditions of comfort and safety.

[0005] However, the use of such an electrical system is not always suitable for the location where the person handling takes place.

[0006] There is therefore a need to find a handling solution that is simple and practical and that allows for use providing optimal comfort and safety for both the person with reduced mobility and for caregivers. Summary of the invention

[0007] The object of the invention relates to a harness having an inner face intended to be in contact with said person with reduced mobility and an outer face intended to be accessible to a caregiver of said person with reduced mobility. The harness comprises a body, a first arm and a second arm extending on either side of the body, defining a space, a first seam delimiting the first arm from the body, a second seam delimiting the second arm from the body, said first seam and said second seam being aligned along the same overall alignment. The body further comprises a main part and a protrusion extending from said main part into the space defined by the first arm and the second arm, said protuberance having an extreme point. The harness is configured so that the overall alignment of the first seam and the second seam passes through said extreme point.

[0008] The shape and structure of the harness conforms to the human body when it is fitted. The specific body cutout eliminates the need to lift the person to put on the harness. When the harness is positioned, the person is enveloped. This significantly reduces the risk of injury for caregivers (musculoskeletal disorders) as well as for the person being transferred.

[0009] When the harness is fitted around the person with reduced mobility, the first and second seams are areas of significant pressure when the person is lifted. Therefore, the harness must be optimally positioned both to avoid discomfort for the person being moved (friction, imbalance, etc.) and to prevent handling risks for caregivers. The first and second seams extend horizontally when the harness is unfolded at rest. Furthermore, the first and second seams face each other on either side of the space defined by the arms. The end point is aligned with the first and second seams, which facilitates positioning the main body of the harness in the lower back of the person being moved.

[0010] In one embodiment, the main part of the body is further delimited by a convex upper limit and a first concave lower limit, said first concave lower limit being connected to the convex upper limit by the first seam. The main part of the body is delimited by a second concave lower limit, said second concave lower limit being connected to the convex upper limit by the second seam. The main part of the body is delimited by a virtual convex limit extending said first concave lower limit towards said second concave lower limit.

[0011] In one embodiment, the protrusion is delimited by the virtual convex limit, a globally convex lower limit present in space E and extending between the first concave lower limit and the second concave lower limit.

[0012] In one embodiment, the overall convex lower limit comprises a first linear part extending the first concave lower limit, a second linear part extending the second concave lower limit, a third rounded part disposed between the first linear part and the second linear part, said extreme point belonging to said third rounded part.

[0013] In one embodiment, the material of the inner face has a mesh texture.

[0014] In one embodiment, the material of the inner face comprises a fabric that stretches in several directions.

[0015] In one embodiment, the outer face includes at least one gripping handle, said gripping handle comprising a fabric core and a plastic shell covering, at least in part, said fabric core.

[0016] In one embodiment, the shell includes a plurality of grooves to facilitate handling by the caregiver.

[0017] In one embodiment, the gripping handle is positioned at one end of the first arm, the positioning and size of said handle being determined so that, at rest, said gripping handle does not extend beyond the end of said first arm.

[0018] In one embodiment, the harness includes a receiving pouch suitable for receiving a hand of the caregiver, said receiving pouch being positioned on the external face of the harness at the level of the main body.

[0019] In one embodiment, the main body of the harness includes internal lumbar reinforcements. Description of the figures

[0037] Fig. 17 illustrates an alternative embodiment of the hook handle of Fig. 6.

[0038] Figures 1 and 2 illustrate a harness 1, according to the invention, in an unfolded position.

[0039] In this position, the harness 1 has a length of at least 142 cm and a width of at least 99 cm.

[0040] The harness 1 also has a weight of less than 1.3 kg. Preferably, the weight of the harness is 1.275 kg.

[0041] Such a harness 1 comprises:

[0042] - a body 10;

[0043] - a first arm 11 and a second arm 12 extending on either side of the body 10 by delimiting a space E.

[0044] The first arm 11 is separated from the body 10 by a first seam 13. This first seam 13 extends along the horizontal direction X.

[0045] The second arm 12 is separated from the body 10 by a second seam 14. This second seam 14 also extends along the horizontal direction X. The second seam 14 is also in the same overall alignment AG as the first seam 13.

[0046] The length of the first arm 11 and the length of the second arm 12 allow the thighs of the person to be handled to be wrapped around them when using the harness.

[0047] The harness also includes a third oblique seam 20 and a fourth oblique seam 21.

[0048] All of these seams 13, 14, 20 and 21 make it possible to join the two sides of the harness 1 while facilitating its folding.

[0049] As is more particularly illustrated in [Fig.3], the body 10 comprises:

[0050] - a main part 100 in the shape of an arch;

[0051] - a protrusion 101 extending from the main part 100 into space E defined by the first arm 11 and the second arm 12.

[0052] The main part 100 is, here, delimited by a convex upper limit 15, the first seam 13, a first concave lower limit 16, a convex virtual limit 18, the second seam 14 and a second concave lower limit 17.

[0053] The first concave lower limit 16 is connected to the convex upper limit 15 by the first seam 13.

[0054] The second concave lower limit 17 is connected to the convex upper limit 15 by the second seam 14.

[0055] The virtual convex limit 18 extends the first lower concave limit 16 towards the second lower concave limit 17.

[0056] The protuberance 101 is delimited by the convex virtual limit 18 and a generally convex lower limit 19.

[0057] The overall convex lower limit 19 is thus present between the first arm 11 and the second arm 12. More particularly, this overall convex lower limit 19 extends between the first concave lower limit 16 and the second concave lower limit 17.

[0058] It will be noted that the third oblique seam 20 extends from the first concave lower limit 16 to the convex upper limit 15.

[0059] Similarly, the fourth oblique seam 21 extends from the second lower concave limit 17 to the upper convex limit 15.

[0060] The third oblique seam 20 and the fourth oblique seam 21 form, here, an angle between 30 and 60 degrees with the horizontal direction X. Preferably, the angle formed is 45 degrees.

[0061] Fig. 4 illustrates in more detail the overall convex lower limit 19. This lower limit 19 comprises a first linear part 191, a second linear part 192 and a third rounded part 193.

[0062] The first linear part 191 extends the first concave lower limit 16.

[0063] The second linear part 192 extends the second concave lower limit 17.

[0064] The third rounded part 193 is arranged between the first linear part 191 and the second linear part 192.

[0065] It will be noted that the extreme point PE belongs to this third rounded part 193. The extreme point PE is the point of the prominence 101 that is furthest forward in space E. In other words, the extreme point PE is the point of the prominence 101 that has the greatest distance D with the virtual convex limit 18.

[0066] As can be seen in [Fig. 5], the inner face F! of the harness 1 comprises a particular texture T. This texture is here a mesh texture allowing for a large flexibility of the material, good "breathing" of the harness as well as increased comfort due to a good distribution of pressure points on the body of the person with reduced mobility.

[0067] Alternatively, the material of the inner surface F! is stretchable in several directions, for example in two opposite directions. This allows the harness to adapt to the contours of the person being moved and to offer a high level of comfort and support. Such a material is, for example, a "Spacer" fabric.

[0068] The outer face FE, visible in [Fig. 2], is composed of a structural polyester fabric coated with high-strength polyurethane that is resistant to abrasion and tearing. This fabric allows for optimized gliding during transfers. In one embodiment, the fabric of the outer face FE conforms to the M2 fire-retardant standard, making it difficult to ignite.

[0069] A finishing strap 22 is used to form the edges of the harness 1. The material of this strap is, for example, identical to that used for seat belts.

[0070] Fig. 6 illustrates an overmolded and ergonomic grip handle 23, intended to be fixed on the external face FE of the harness.

[0071] The grip handle 23 comprises a fabric core 231 and a rigid, pre-formed plastic shell 232. The shell 232 covers, at least partially, said fabric core 231.

[0072] The fabric core 231 is attached to the harness 1 via cross seams 233 at two ends of said core.

[0073] The shell 232 comprises a main part 2321 and a central part 2322 comprising a plurality of slots 2323 revealing the fabric core 231.

[0074] This design of the gripping handle 23 makes it easier for a caregiver to grasp said handle.

[0075] In [Fig.2], ten gripping handles 23A, 23B, 23C, 23D are positioned on the external face FE of the harness.

[0076] The 23A gripping handles are back grips.

[0077] The 23B gripping handles are upper side handles.

[0078] The 23C gripping handles are lower side handles.

[0079] The 23D grip handles are upper thigh return handles.

[0080] The 23E grip handles are lower thigh return handles.

[0081] The gripping handles 23A, 23B, 23C are present at the body 10. The handles 23D, 23E are positioned at the end of the arms 11, 12.

[0082] This arrangement of handles 23A, 23B, 23C, 23D, 23E allows for an optimized distribution of the person's weight, which facilitates the work of caregivers during the movement operation, particularly at the time of lifting.

[0083] Figure 7 illustrates more specifically the positioning of the gripping handles 23A, 23B, 23C, 23D, 23E when the person with reduced mobility is enveloped by harness 1.

[0084] The gripping handles 23A, 23B and 23C (two on each side of the person) are located on the person's back.

[0085] The gripping handles 23D, 23E (two on each side of the person) are located at the level of the person's thighs.

[0086] Figure 8 illustrates more specifically the positioning of the grip handle 23E at one end of one of the arms 10, 11. The length L of the fabric core 231 and the position of the cross seams 233 are determined so that the hook handle 23E, at rest, does not exceed the end of the arm 10, 11.

[0087] Thus, when handling the harness 1, care is taken to ensure that the attachment handles 23E always remain on the same side, i.e., on the side of the external face FE. This facilitates the placement of the harness 1 around the person and the grasping of the attachment handles 23E by caregivers.

[0088] It should be noted that the attachment handles 23A, 23B, 23C, 23D, 23E can be of different colours in order to facilitate the placement of the harness 1 around the person, by the caregiver.

[0089] Figure 17 thus illustrates a variant embodiment of the gripping handle in in which two colored bands 2311, 2312 are positioned on the fabric core 231 on either side of the shell 232. Such a configuration facilitates the manufacture of gripping handles that can have different colors.

[0090] Figures 9 and 10 illustrate an alternative embodiment in which the harness 1 includes a receiving pouch 24 at the level of the main part 100 of the body 10. This receiving pouch 24 is disposed on the external face FE.

[0091] In the embodiment of Figures 9 and 10, the receiving pouch 24 is arranged near the convex virtual boundary 18.

[0092] Figure 10 details a cross-sectional view of the receiving pouch 24. This pouch The receiving pouch 24 comprises a front portion 241 and two side portions 242 (only one of which is shown here). The front portion 241 is attached, at its lower end, to the outer surface FE of the harness, at the level of the convex virtual boundary 18. The two side portions 242 are attached to the front portion 241 of the receiving pouch 24 and to the outer surface FE of the harness 1. The front portion 241, the two side portions 242, and the outer surface FE define a volume V in which all or part of a caregiver's hand can be placed. This facilitates the overall positioning of the body 10 against the back of the person with reduced mobility during the fitting of the harness 1.

[0093] Figure 11 illustrates another embodiment in which the body 10 Includes 25 lumbar supports. These 25 lumbar supports facilitate support of the back of the person with reduced mobility during a transfer using the harness 1. Advantageously, the lumbar reinforcements 25 remain in the main part 100 of the body 10 and do not extend beyond the virtual convex limit 18, that is to say they do not extend into the protuberance 101. Thus the protuberance 101 retains a certain flexibility, in particular for its placement against the back of the person with reduced mobility.

[0094] Figures 12 to 16 illustrate the different stages of putting the harness on around the person with reduced mobility.

[0095] A person with reduced mobility is, for example:

[0096] - a person weakened by a medical problem and who cannot transfer alone, under optimal conditions of comfort and safety;

[0097] - an obese person. The harness 1 allows for intervention in better conditions (better grip, intervention by 3 or even 4 caregivers for better weight distribution). The maximum weight that harness 1 can support is, for example, around 140 kg. The use of harness 1 is also suitable in more confined environments, for example in an airplane, where the number of possible caregivers is more limited;

[0098] - a person who has fallen and is unable to get up without assistance, in a confined space (during a fire department intervention, for example).

[0099] Caregivers using the harness include, for example:

[0100] - Airport assistance agents required to handle persons with reduced mobility reduced;

[0101] - members of intervention teams (firefighters, paramedics, etc.);

[0102] - staff of medical-social establishments or hospitals;

[0103] - caregivers, home-based professionals, who are required to handle people in the absence of patient lifts.

[0104] These caregivers can therefore use the harness in all places where the handling and installation of people cannot be done in a conventional way.

[0105] Before the manipulation, the caregivers:

[0106] - identify the type of transfer to be carried out;

[0107] - determine the type of transfer, for example from a wheelchair to a seat transfer, from the transfer seat to the aircraft seat, during reinstallation from the ground to a bed or armchair, etc.;

[0108] - are considering a manual lifting of the person;

[0109] - assess the possibility of carrying out the transfer using the harness;

[0110] - evaluate the frequency of the transfer;

[0111] - assess the equipment involved during the transfer: the wheelchair, the bed, the chair, the shower chair, etc.

[0112] Before handling the person, caregivers take into account the specific characteristics of the person to be handled:

[0113] - his medical condition: nature of his motor deficit, joint limitations, muscle tone different parts of the body, etc.;

[0114] - its skin condition;

[0115] - its size;

[0116] - its morphology;

[0117] -its weight;

[0118] - its ability to assist during the transfer;

[0119] - its balance in assisted position and / or trunk tone;

[0120] - acceptance of the transfer and general behavior.

[0121] Before the procedure, caregivers also take the environment into account:

[0122] - by ensuring that there is enough space around the person to perform its transfer;

[0123] - by ensuring that the lighting is sufficient;

[0124] - by checking that the ground is flat, smooth and free of obstacles.

[0125] The manipulation of the person takes place in the following manner:

[0126] - it is necessary, firstly, to respect the ergonomic principles of the back. Indeed, harness 1 is designed to facilitate handling;

[0127] - slide the body 10 of the harness 1 behind the person and adjust so that the upper part of body 10 is located at shoulder height, as can be seen in [Fig.12];

[0128] - slide the first arm 11 and the second arm 12 on each side of the person;

[0129] - bring the legs of the person to be handled closer together and then slide both arms 11,12 under the thighs one after the other, as flat as possible, as can be seen in [Fig.13];

[0130] - the entire body 10 of the harness 1 is then lowered completely to the level from the person's back. To do this, one of the caregivers can slide a hand into the pocket 24 and slide the body 10 vertically until the extreme point PE comes against the seat 26 on which the person is sitting. In this position, the first seam 13 and the second seam 14 are ideally placed at the level of the person's thighs and the harness is in an optimal position for transferring the person, as can be seen in [Fig. 14];

[0131] - perfect coordination between professionals is necessary. Thus, for a As shown in [Fig. 14], two-user operation is possible. One user at the rear uses the upper side handles 23B, the lower side handles 23C, and the rear handles 23A (not visible in [Fig. 14]). The user at the front uses the upper thigh return handles 23D and the lower thigh return handles 23E. [Fig. 15] illustrates a manipulation of the person with three caregivers.

[0132] Figure 16 shows the person with reduced mobility in a wheelchair once the transfer has been completed. To remove the harness 1, the caregiver must loosen the first arm 11 and the second arm 12 from the person's thighs and lift the body 10 of the harness 1 upwards, using the various attachment handles 23A, 23B, 23C.

[0133] Aligning the extreme point PE with the first seam 13 and the second seam 14 allows for easier verification of proper harness installation 1 just before handling [Fig. 14]. Safety and comfort adjustments are thus more easily made before transfer.
