Description

Technical Field

[0001] This utility model relates to the field of prosthetics technology, specifically to an exhaust device for a prosthetic socket. Background Technology

[0002] The socket is a component that comfortably houses the silicone sleeve of the residual limb and effectively transmits forces to the distal end of the prosthesis; it serves as the interface between the human body and the mechanical system. Therefore, a proper socket fit refers to the optimal fit between the socket and the silicone sleeve of the residual limb. A "good fit" is defined as a functional fit that conforms to anatomical, biological, and biomechanical principles. The effectiveness of the socket depends entirely on its proper fit.

[0003] Currently, after a period of use, muscle atrophy in the stump of prostheses leads to increased air space within the socket, which impairs the socket's suction function, hinders walking, and impacts daily life. This necessitates frequent replacements of the socket and silicone sleeve components, increasing the financial burden on disabled users. Furthermore, traditional sockets and silicone sleeves are relatively expensive, impractical, and not easily adopted for widespread use. Utility Model Content

[0004] This utility model provides an exhaust device for a prosthesis socket, aiming to solve the problems mentioned in the background art. Traditional exhaust valves can only exhaust air to a relatively weak degree and cannot perform air extraction operations, resulting in a large amount of air inside the prosthesis socket during use. This prevents the user's residual limb silicone sleeve end from exerting sufficient force, affecting the user experience. Moreover, traditional prosthesis sockets require the use of relatively expensive silicone sleeves, which reduces their practicality and makes them inconvenient for widespread use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an exhaust device for a prosthetic socket, comprising a prosthetic socket fitted over the outside of a silicone sleeve of the residual limb and an exhaust assembly fixedly disposed at the lower end of the prosthetic socket; the exhaust assembly includes a first one-way exhaust valve detachably mounted on the outside of the prosthetic socket, a suction cup fixedly adsorbed onto the first one-way exhaust valve, a three-way tube fixedly connected to the suction cup, a miniature vacuum motor fixedly mounted at the lower end of the outside of the prosthetic socket and connected to one end of the three-way tube, a second one-way exhaust valve connected to the other end of the three-way tube, and a control component fixedly mounted on one side of the miniature vacuum motor; the control component includes a main control circuit board and a switch, the switch being electrically connected to the main control circuit board, and the main control circuit board being electrically connected to the miniature vacuum motor.

[0006] When the above-mentioned device starts working, the main control circuit board is activated by a switch. The micro vacuum motor is connected to the three-way tube, which uses a suction cup to extract air from the inside of the prosthesis socket. This allows the prosthesis socket to fit snugly against the outside of the residual limb silicone sleeve, enabling the user's residual limb silicone sleeve to exert force and providing a better user experience. A second one-way exhaust valve is installed at the end of the three-way tube, which can be used to expel air from the inside of the prosthesis socket when the residual limb silicone sleeve is inserted into it.

[0007] Preferably, the micro vacuum motor has an air inlet and an air outlet on one side, and the air inlet is connected to one end of the three-way pipe.

[0008] Preferably, the first one-way exhaust valve includes a positioning rubber ring fixedly embedded on the outside of the prosthesis receiving cavity and an exhaust valve body adapted to the positioning rubber ring.

[0009] Preferably, a sponge pad for contacting the silicone sleeve of the residual limb is fixedly installed inside the prosthesis receiving cavity.

[0010] Preferably, the outer side of the silicone sleeve of the stump is coated with an annular adhesive layer that is compatible with the prosthesis receiving cavity.

[0011] Preferably, the control component also includes a battery for powering the miniature vacuum motor and the main control circuit board.

[0012] The exhaust device of this prosthetic socket is simple in structure and easy to use. The main control circuit board is activated by a switch, and a miniature vacuum motor connects to a three-way tube. The three-way tube uses a suction cup to extract air from the inside of the prosthetic socket, allowing the socket to fit snugly against the outside of the residual limb silicone sleeve. This allows the user's residual limb silicone sleeve to exert force effectively, improving the user experience. A second one-way exhaust valve at the end of the three-way tube can be used to expel air from the inside of the prosthetic socket when the residual limb silicone sleeve is inserted. A ring-shaped adhesive layer is coated on the outside of the residual limb silicone sleeve, making the contact surface between the outer surface of the sleeve and the inner wall of the socket tighter, providing airtightness and improving the exhaust effect.

[0025] When automatic venting is achieved, the specific venting route is as follows: the air inside the prosthesis receiving cavity 1 is vented from the first one-way venting valve 21 into the three-way pipe 23, then drawn from the three-way pipe 23 into the micro vacuum motor 24, and finally discharged from the venting port 242.

[0026] When performing daily venting, the specific venting route is as follows: air inside the prosthesis socket 1 is forced into the three-way pipe 23 through the first one-way vent valve 21, and then discharged through the second one-way vent valve 25 at the end of the driven three-way pipe 23.

[0027] The main control circuit board 261 is activated by switch 262. The micro vacuum motor 24 is connected to the three-way tube 23.

[0030] In one embodiment, the first one-way exhaust valve 21 includes a positioning rubber ring 211 fixedly embedded on the outside of the prosthesis receiving cavity 1 and an exhaust valve body 212 adapted to the positioning rubber ring 211.

[0031] In this embodiment, refer to Figure 1 and Figure 2 The exhaust valve body 212 can be detached from the positioning rubber ring 211, which facilitates assembly and improves wearing efficiency.

[0032] In one embodiment, a sponge pad 11 for contacting the silicone sleeve of the residual limb is fixedly installed inside the prosthesis receiving cavity 1.

[0033] In this embodiment, refer to Figure 2 By placing a sponge pad 11 inside the prosthesis socket 1, the prosthesis socket 1 provides cushioning for the residual limb during walking, thus improving the comfort of the patient's residual limb.

[0034] In one embodiment, the outer side of the stump silicone sleeve is coated with an annular adhesive layer 3 that is compatible with the prosthesis receiving cavity 1.
