Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a foot decompression device for diabetic foot. Background Technology

[0002] Diabetic foot disease is one of the common chronic complications of diabetes, and diabetic foot ulcers are its most common manifestation. Prevention and treatment of diabetic foot ulcers can significantly reduce the amputation rate, mortality rate and medical costs of diabetic patients.

[0003] While existing devices reduce foot pressure during walking through airbags and elastic layers, the sole of the injured area is lower than the rest of the foot after medication and bandaging. When the shoe upper is flat, the pressure on the injured area increases, hindering local blood circulation and affecting the patient's recovery. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a foot decompression device for diabetic foot, which increases the distance between the injured area of ​​the patient's foot and the decompression mechanism, thereby minimizing the increase in pressure caused by applying medication and bandaging to the injured area.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foot decompression device for diabetic foot includes a sole, a decompression mechanism disposed within the sole, and a pair of shoe uppers spaced laterally on the sole. The sole has an internal cavity, and the upper surface of the sole has several mounting channels spaced apart, with the bottom of the upper channel communicating with the cavity. The decompression mechanism includes a decompression airbag fixed within the cavity and several massage components movably inserted through each mounting channel and detachably connected to the decompression airbag. Each massage component includes a mounting base movably inserted through the mounting channel and detachably connected to the decompression airbag, a circumferentially rotatable rotating shaft mounted within the mounting base, and several massage protrusions spaced apart and fixed to the outer surface of the rotating shaft.

[0007] More preferably, a quick-release assembly is provided between the multiple mounting bases and the decompression airbag, and each mounting base is detachably connected to the decompression airbag through the quick-release assembly; the quick-release assembly includes multiple hook surfaces fixed to the lower surface of each mounting base and a rough surface fixed to the upper surface of the decompression airbag and cooperating with the multiple hook surfaces.

[0008] More preferably, each upper assembly includes a first connecting sticker fixed to one side of the sole and a second connecting sticker fixed to the other side of the sole and cooperating with the first connecting sticker.

[0009] More preferably, the lower surface of the shoe sole is covered with an anti-slip pad.

[0010] More preferably, the upper surface of the sole is covered with a sweat-absorbing layer.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model does not install a mounting seat on the injured area of ​​the patient's foot during use, thereby increasing the distance between the injured area of ​​the patient's foot and the pressure relief mechanism. This provides space under the injured area to minimize the increase in pressure during walking caused by the injured area being lower than the rest of the foot after the patient has applied medication and bandages. This reduces the obstruction of blood circulation in the injured area and improves the patient's recovery speed.

[0013] 2. During the patient's walking process, the massage protrusions fixed on the outside of the rotating shaft can perform a pressing massage on the patient's feet. When the patient does not need to walk, the rotating shaft can be rotated by sliding on the sole of the shoe, thereby realizing a back-and-forth rolling massage on the patient's feet to improve blood circulation in the patient's feet.

[0014] 3. This utility model can adjust the space between the shoe upper and the sole by using the cooperation of the first connecting sticker and the second connecting sticker, so that the patient's foot fits the shoe upper as closely as possible, thereby improving the patient's comfort.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] A foot decompression device for diabetic foot includes a sole 1, a decompression mechanism 2 disposed within the sole 1, and a pair of shoe uppers 3 spaced laterally on the sole 1. The sole 1 has a cavity 11 inside, and the upper surface of the sole 1 has a plurality of mounting channels 12 spaced apart, the bottom of which communicate with the cavity 11. The decompression mechanism 2 includes a decompression airbag 21 fixed within the cavity 11 and a plurality of massage components 22 movably inserted through each mounting channel 12 and detachably connected to the decompression airbag 21. Each massage component 22 includes a mounting base 221 movably inserted through the mounting channel 12 and detachably connected to the decompression airbag 21, a circumferentially rotatable rotating shaft 222 mounted within the mounting base 221, and a plurality of massage protrusions 223 spaced apart and fixed on the outer surface of the rotating shaft 222.

[0024] When using this device, except for the mounting seat 221 at the injured part of the patient's foot, the other mounting seats 221 are passed through the corresponding mounting channels 12 and installed on the decompression airbag 21. Then, the front of the patient's foot is inserted into the space between the sole 1 and the upper 3 of the shoe.

[0025] As a possible implementation of this solution, preferably, a quick-release assembly 23 is provided between the multiple mounting seats 221 and the decompression airbag 21, and each mounting seat 221 is detachably connected to the decompression airbag 21 through the quick-release assembly 23; the quick-release assembly 23 includes multiple hook surfaces 231 fixed on the lower surface of each mounting seat 221 and rough surfaces 232 fixed on the upper surface of the decompression airbag 21 and fixed in cooperation with the multiple hook surfaces 231; the cooperation of the hook surfaces 231 and the rough surfaces 232 can realize the quick disassembly and installation of the mounting seats 221, thereby improving the comfort level when using this device.

[0026] As a possible implementation of this solution, preferably, each shoe upper 3 includes a first connecting sticker 31 fixed to one side of the sole 1 and a second connecting sticker 32 fixed to the other side of the sole 1 and fixed in cooperation with the first connecting sticker 31; the space between the shoe upper 3 and the sole 1 can be adjusted by the cooperation of the first connecting sticker 31 and the second connecting sticker 32 so that the patient's foot fits the shoe upper 3 as closely as possible, thereby improving the patient's comfort.

[0027] As a possible implementation of this solution, preferably, the lower surface of the sole 1 is covered with an anti-slip pad 13; the anti-slip pad 13 can increase the friction between the sole 1 and the ground, thereby minimizing the risk of the patient slipping.

[0028] As a possible implementation of this solution, preferably, the upper surface of the sole 1 is covered with a sweat-absorbing layer 14; the sweat-absorbing layer 14 can absorb the sweat from the patient's feet to avoid sweat flowing to the injured area of ​​the patient's feet as much as possible, thereby minimizing secondary infection of the injured area of ​​the patient's feet caused by sweat.
