Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training accessories, in particular to a limb fixing device. Background Art

[0002] Patients with limb injuries need to use appropriate rehabilitation training equipment after surgery to help them recover their limb functions.

[0003] Since the injured limb is relatively weak, the patient needs to bind the limb to a limb fixation device when using the rehabilitation training equipment, so that the rehabilitation training device can guide the limb to perform corresponding rehabilitation training movements through the limb fixation device.

The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] refer to Figures 1 to 3A limb fixing device according to a preferred embodiment of the present invention will be described in detail below. The limb fixing device includes a rigid fixing mechanism 10, a restraining mechanism 20 and a mounting assembly 30.

[0025] The rigid fixing mechanism 10 forms a limiting groove 1001 and an opening 1002 communicating with the limiting groove 1001. The limb can move into and out of the limiting groove 1001 through the opening 1002. The rigid fixing mechanism 10 provides rigid support for the limb to fix the limb.

[0026] The mounting assembly 30 includes a mounting member 31. The mounting member 31 is wrapped around the outer periphery of the rigid fixing mechanism 10. The mounting member 31 is made of textile material to increase the comfort of the limb fixing device.

[0027] It is worth mentioning that the rigid fixing mechanism 10 and the mounting member 31 jointly form at least one assembly hole 101 , and fasteners such as screws can pass through the assembly hole 101 to mount the limb fixing device on the rehabilitation training equipment for supporting use.

[0028] The restraint mechanism 20 is mounted on the mounting member 31 . The restraint mechanism 20 is used to fix the limb to the limb fixing device to prevent relative movement between the limb and the limb fixing device during rehabilitation training of the patient.

[0029] Preferably, the mounting member 31 defines a hidden space 3101 and an access opening 3102 communicating with the hidden space 3101. The rigid fixing mechanism 10 can be moved into and out of the hidden space 3101 through the access opening 3102. This allows the rigid fixing mechanism 10 within the hidden space 3101 to be removed from the access opening 3102, thereby separating the mounting assembly 30 and the rigid fixing mechanism 10 for easier cleaning. It will be appreciated that after a fastener such as a screw is inserted through the assembly hole 101, the mounting member 31 is assembled to the rigid fixing mechanism 10 via the screw.

[0030] Specifically, the rigid fixing mechanism 10 includes a support body 11. The support body 11 includes a supporting portion 111 and two side portions 112. The two side portions 112 are respectively mounted on the two ends of the supporting portion 111, and the two side portions 112 and the supporting portion 111 together form the limiting groove 1001. The two side portions 112 together form the opening 1002 that communicates with the limiting groove 1001.

[0031] In one embodiment, the two side portions 112 are pivotally mounted to the ends of the support portion 111, allowing the size of the opening 1002 and the retaining slot 1001 to be adjusted. In this way, the side portions 112 can adjust the size of the retaining slot 1001 and the opening 1002 according to the size of the limb inserted into the retaining slot 1001, allowing the limb restraint device to adapt to limbs of varying thicknesses.

[0032] As a deformable form, the two side portions 112 and the supporting portion 111 are integrally formed, and a preset angle is formed between the side portions 112 and the supporting portion 111 .

[0033] Furthermore, the rigid fixing mechanism 10 also includes two stoppers 12 and two pairs of connecting members 13. Each of the connecting members 13 is respectively connected to a stopper 12 and an end of the side portion 112 away from the supporting portion 111. The stopper 12 is pivotally mounted on the side portion 112 via the connecting member 13, so that the two stoppers 12 can cover or open the opening 1002. That is, after the limb moves into the limiting groove 1001, the two stoppers 12 rotate in the direction of covering the opening 1002, so that the stoppers 12 fix the side of the limb facing the opening 1002. In this way, the rigid fixing mechanism 10 can wrap the limb in all directions to provide comprehensive support for the limb, thereby preventing the limb from moving relative to the limb fixing device and further improving stability.

[0034] In one example, the connecting element 13 is implemented as a hinge.

[0035] Specifically, the restraint mechanism 20 includes a mounting belt 21 and at least one connecting mechanism 22 . The connecting mechanism 22 includes a first assembly structure 221 and a second assembly structure 222 .

[0036] In one embodiment, the restraint mechanism 20 is provided with at least one pair of mounting belts 21, and the two mounting belts 21 in each pair are mounted on both ends of the mounting member 31. The first assembly structure 221 and the second assembly structure 222 are respectively mounted on the two mounting belts 21 in a pair.

[0037] As a preferred embodiment of the previous embodiment, the first assembly structure 221 is engaged with the second assembly structure 222 in a detachable manner.

[0038] Specifically, either the first assembly structure 221 or the second assembly structure 222 is implemented as a sub-buckle; the other is implemented as a female buckle.

[0039] As another preferred embodiment of the previous embodiment, the first assembly structure 221 is adhered to the second assembly structure 222 in a detachable manner.

[0040] Specifically, either the first assembly structure 221 or the second assembly structure 222 is implemented with a fleece-surface Velcro; the other is implemented with a hook-surface Velcro.

[0041] It is worth mentioning that the restraint mechanism 20 may not be provided with the connecting mechanism 22. In this case, the two mounting straps 21 in each pair are respectively installed at the two ends of the mounting assembly 30 in a manner that can be untied to prevent the limb from moving out of the limiting groove 1001 from the opening 1002.

[0042] In another embodiment, the restraint mechanism 20 includes a mounting strap 21, which is attached to one end of the mounting member 31. The first assembly structure 221 is detachably attached to the second assembly structure 222. In this embodiment, either the first assembly structure 221 or the second assembly structure 222 is implemented with a loop-type Velcro; the other is implemented with a hook-type Velcro.

[0043] The first assembly structure 221 is implemented with a fleece-surface Velcro; the second assembly structure 222 is implemented with a hook-surface Velcro.

[0044] As a preferred embodiment of this embodiment, one of the first assembly structure 221 and the second assembly structure 222 is mounted on the mounting belt 21, and the other is mounted on the outer peripheral wall of the mounting member 31. After the mounting belt 21 passes through the opening 1002, it is attached to the mounting member 31 by the first assembly structure 221 and the second assembly structure 222, thereby securing the limb to the limiting slot 1001.

[0045] As another preferred embodiment of this embodiment, the first assembly structure 221 and the second assembly structure 222 are both installed on the same side of the mounting belt 21, and a through-hole 3003 is formed at one end of the mounting component 30 away from the mounting belt 21. The end of the mounting belt 21 away from the mounting component 30 passes through the through-hole 3003 and wraps back to the end of the mounting member 31 away from the mounting component 30 to form the through-hole 3003. The mounting belt 21 fixes the limb to the limiting groove 1001 by gluing the first assembly structure 221 and the second assembly structure 222.

[0046] In one embodiment, the through hole 3003 is formed at one end of the mounting member 31 .

[0047] Alternatively, the mounting assembly 30 may further include a connecting buckle 32, which is mounted on an end of the mounting member 31 away from the mounting strap 21 and forms the through-hole 3003. The connecting buckle 32 has a predetermined hardness, such that the through-hole 3003 formed by the connecting buckle 32 is stable in shape, facilitating the insertion of the mounting strap 21 therethrough.

[0048] Furthermore, the limb fixing device further includes at least one buffer pad 40 .

[0049] The cushioning pad 40 is placed in the limiting groove 1001 formed by the supporting body 11 to improve the comfort of the limb fixation device, and a predetermined number of the cushioning pads 40 can be selected according to the thickness of the user's limbs so that the user's limbs can be adapted to the limb fixation device through the cushioning pad 40 to prevent the limbs from shaking in the limiting groove 1001.

[0050] Furthermore, the limb fixing device further includes at least one connecting member 50 .

[0051] The connecting member 50 includes a first connecting structure 51 and a second connecting structure 52. The first connecting structure 51 is detachably attached to the second connecting structure 52. The first connecting structure 51 and the second connecting structure 52 of the connecting member 50 are respectively mounted on a side of the cushion pad 40 and a side of the mounting member 31 facing the opening 1002.

[0052] When the limb fixation device is provided with a plurality of the buffer pads 40, two adjacent buffer pads 40 are respectively installed with a first connecting structure 51 and a second connecting structure 52, so that the buffer pads 40 remain stable during use by the patient, and the buffer pads 40 are prevented from being moved out of the limiting groove 1001 due to friction.

[0053] In one example, either the first connection structure 51 or the second connection structure 52 is implemented as a Velcro with a fleece surface; the other is implemented as a Velcro with a hook surface.

[0054] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
