Description

Technical Field

[0001] This utility model relates to the field of lower limb joint rehabilitation technology, and more specifically, to a lower limb joint rehabilitation fixation device. Background Technology

[0002] After hip replacement surgery, the recovery process is lengthy and requires stabilization of the lower limbs to maintain a neutral position (extended with toes pointing upwards) while the patient is lying down. This prevents prosthesis dislocation due to lateral movement and promotes recovery. Current techniques typically use simple braces with straps for lower limb stabilization. The straps bind the patient's foot to the brace to help maintain a neutral position. However, this structure lacks width adjustment, making it ineffective for patients with excessively large or small feet. Furthermore, the rigidity of the brace can cause discomfort during application or prolonged use, hindering its use. Additionally, prolonged poor blood circulation after lower limb injury can lead to cold extremities; foot stabilization further impedes blood flow, hindering recovery. Utility Model Content

[0003] This invention overcomes the shortcomings of the prior art where poor blood circulation occurs when using a brace to keep the patient's lower limbs in a neutral position. It provides a lower limb joint rehabilitation fixation device that can promote blood circulation in the patient's lower limbs to a certain extent and promote rehabilitation when fixing the patient's lower limbs.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lower limb joint rehabilitation fixation device, comprising: a groove, an end plate connected to the groove, a binding assembly connected to the groove, a heating assembly detachably connected to the end plate, and a filling assembly.

[0005] The trough has a through groove containing a filling component. One end plate is connected to the trough, and binding components are attached to both sides. The end plate is positioned at one end of the through groove and connected to a heating component. During use, the patient's foot is placed in the through groove, with the end plate supporting the sole. The filling component fills the gaps in the through groove, and the binding components then secure the patient, keeping the toes pointing upwards to maintain a neutral lower limb position, facilitating rehabilitation. Simultaneously, the heating component on the end plate heats the patient's foot, promoting healing. This device improves blood circulation in the feet and lower limbs, further promoting patient recovery. The filling component features a flexible working surface, meaning its surface is relatively soft and can effectively wrap and secure the patient's feet. Specific materials include sponge blocks, soft pads, and airbags. The filling component prevents direct contact between the patient's feet and the tank, avoiding hard compression that could impede blood flow and ensuring proper blood circulation in the feet. It also provides cushioning, enhancing the comfort of the device. The heating component is detachably connected to the end plate for convenient use.

[0006] Preferably, it further includes a control component disposed on the tank or the end plate, the heating component including a plug plate slidably connected to the end plate and a heating element connected to the plug plate, the heating element being signal-connected to the control component.

By using the filling component 6 to ensure blood circulation in the patient's foot, a heating component 4 is provided to heat the patient's foot, thereby further promoting blood circulation in the patient's foot and promoting recovery.

[0039] Example 2

[0040] The difference between Example 1 and Example 2 is as follows:

[0041] like Figure 1-3 As shown, it also includes a control component 5 disposed on the groove 1 or end plate 2. The heating component 4 includes an insert plate 401 slidably connected to the end plate 2 and a heating element 402 connected to the insert plate 401. The heating element 402 is signal-connected to the control component 5. A horizontal plate 403 is provided at the top of the insert plate 401, and first magnetic elements 404 are provided at the bottom of both ends of the horizontal plate 403.

Further, the heating element 402 is a sea salt heating pack, which generally includes a main body, a sea salt layer disposed within the main body, and a heating element. The heating element is externally connected to a data cable and interface for connecting to an external power source. The detachable connection between the heating element 402 and the insert plate 401 can be achieved using snap-fit, snap-fit ​​fixing strips, or snap-fit ​​fixing frames, etc. Specifically, the heating parameters of the heating component 4 are set by the control component 5. The control component 5 is set on the end plate 2 or the tank 1 for easy operation. The control component 5 and the heating component 4 are connected by wired or wireless signals. When setting up a wired signal connection, a pluggable data cable and connector are required. The first magnetic component 404 and the second magnetic component 201 attract each other, so that the insertion plate 401 can be stably fixed on the end plate 2. The two ends of the horizontal plate 403 protrude from both sides of the insertion plate 401. The first magnetic component 404 is set at the bottom of both ends of the horizontal plate 403.

[0043] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0044] Example 3

[0045] Based on Example 1 or Example 2, Example 1 or Example 2 are further defined, with the following differences:

[0046] like Figure 1-3As shown, the binding assembly 3 includes at least two binding straps 301 connected at one end to the groove 1, a first fastener 302 connected to the other end of the binding straps 301, and a second fastener 303 connected to the groove 1. The first fastener 302 and the second fastener 303 are detachably connected. The binding assembly 3 also includes at least two sliders 304 slidably connected to the groove 1, and the binding straps 301 are fixedly connected to the sliders 304 respectively. Multiple limiting members 305 for restricting the movement of the binding straps 301 are provided on both sides of the groove 1, and the limiting members 305 are provided with limiting holes. The first fastener 302 and the second fastener 303 are Velcro.

[0047] The binding strap 301 is used to fix the patient's foot inside the groove 1, and also to prevent the patient's foot from falling out of the groove 1 or the airbag 601. The first fixing member 302 and the second fixing member 303 are detachably connected, thereby making the binding strap 301 stably connected to the groove 1. The first fixing member 302 and the second fixing member 303 can be made of buckles, snaps, Velcro, etc. Furthermore, the binding strap 301 is an elastic band. A slider 304 is set to move the binding strap 301 to facilitate use. Specifically, the slider 304 is restricted to the side of the groove 1, and can slide left and right without falling out of the groove 1. After the slider 304 moves with the binding strap 301, it passes through the limiting hole of the moving limiting member 305 of the binding strap 301, and then the first fixing member 302 is connected to the second fixing member 303 to prevent the binding strap 301 from shaking during use after movement. The first fastener 302 and the second fastener 303 can be either a textured surface or a hook surface, and are designed with Velcro for easy use. Furthermore, the second fastener 303 is extended on the side of the groove 1, and all the first fasteners 302 are connected to one second fastener 303.

[0048] Furthermore, such as Figure 2 As shown, in this embodiment, the control component 5 includes a touch screen and control buttons.

[0049] The working principle of this embodiment is as follows: During use, the patient's lower limb is placed on the airbag 601 in the middle of the tank 1, ensuring the patient's foot is in contact with the end plate 2. Then, the inflation port 602 is opened, and a small air pump is connected to the inflation port 602 for inflation. During inflation, the airbag 601 is wrapped and fixed according to the size and shape of the patient's lower limb. After inflation, the small air pump is removed, and the inflation port 602 is sealed. The two openings at the top of the inflated airbag 601 are secured with binding ropes to prevent loosening. The binding straps 301 at both ends are adjusted using the horizontal sliding slider 304. Depending on the patient's actual condition, the limiting member 305 is inserted, allowing air to pass through the top of the airbag 601. The part is wrapped around the other end of the limiting member 305 and inserted. It is then fixed by Velcro, namely the first fixing member 302 and the second fixing member 303, to achieve double binding and fixation, which is easy to disassemble. The control component 5 heats the part at a time, so that the heating element 402 absorbs heat through electric heating. The heat is then transferred to the body by applying heat to the patient's soles, thereby relieving pain and promoting blood circulation. It effectively warms the patient's cold lower limbs. According to the patient's needs, the insert 401 carrying the heating element 402 can be pulled out and replaced with different inserts 401, making the overall structure simple, portable, and with good binding and fixation effect.
