Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, specifically an auxiliary tool for wearing elastic stockings. Background Technology

[0002] Venous thromboembolism (VTE) is a common postoperative complication, mainly including deep venous thromboembolism (DVT) and pulmonary embolism (PE). Its incidence is high, seriously threatening patients' lives and health. Research data shows that the incidence of VTE in postoperative patients can reach 13.5%-25.2% across various surgical specialties. Therefore, taking effective preventive measures to reduce the incidence of postoperative VTE has significant clinical and social value. Compression stockings, as a common method of physical prevention of VTE, have been widely used in clinical practice. By applying gradient pressure to the lower limbs, compression stockings promote venous blood return, reduce blood stasis, and thus reduce the risk of thrombosis. Multiple studies have shown that wearing compression stockings during the perioperative period can significantly reduce the incidence of VTE, especially for high-risk patients, where the effect is more pronounced. However, wearing compression stockings requires certain skills, and it can be difficult to wear them independently. Improper wearing of medical compression stockings may cause discomfort such as redness and swelling in the lower limbs. Because the stockings are usually tight, wearing them is time-consuming and laborious, which has a greater impact on obese, bedridden, frail, and elderly patients, and may even reduce patient compliance. This not only affects the effectiveness of the compression stockings but may also cause unnecessary pain to the patient.

[0003] Therefore, this utility model provides an auxiliary tool for wearing elastic stockings to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an auxiliary tool for wearing elastic stockings, thus solving the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tool for wearing elastic stockings, comprising:

[0006] The auxiliary wearable structure is integrally welded together from a main expansion frame, a rear bracket, and a side support. An electrical socket is installed on the upper side of the main expansion frame via bolts and plastic clips on the rod of the side support near the main expansion frame. The lower side of the electrical socket has a power inlet. The electric actuator is pushed parallel to the side support rod to connect to the electrical socket. The output rod of the electric actuator has an open mounting threaded hole that engages with a Z-shaped pull rod. A medicine tube is connected parallel to the support rod on the side of the electric actuator near the main expansion frame. A spray piston reciprocates along the inner wall of the medicine tube, with one end of the spray piston extending from the medicine tube to the pull rod and perpendicularly engaging with it. An L-shaped spray channel runs through the spray piston from the piston end to the end connected to the pull rod along its axis.

[0007] Preferably, the main expansion frame has an inclined semi-annular open sleeve, and U-shaped side supports and double L-shaped rear brackets are welded to the surface of the C-shaped base frame on the left and right sides and the rear side, respectively. The side supports are vertically arranged on both sides of the main expansion frame, and the rear brackets are parallel to the rear side of the main expansion frame. Both the side supports and the rear brackets are inclined at the same angle as the main expansion frame.

[0008] Preferably, the pull rods are positioned parallel to each other on the left and right sides of the main expansion frame after connection.

[0009] Preferably, there is space reserved between the pull bar and the main expansion frame to allow the elastic stockings to be placed and moved on the main expansion frame.

[0010] Preferably, a liquid supply bottle is threadedly installed at the connection port at the upper end of the medicine tube.

[0011] Preferably, the port connecting the supply bottle to the drug tube and the input port at the opposite end of the drug tube are both equipped with one-way valves, so that the auxiliary therapeutic agent inside the supply bottle can be unidirectionally input into the drug tube.

[0012] Preferably, the spray channel is equipped with a nozzle for spraying the agent at an open port near the pull rod. Beneficial effects

[0013] This invention provides an auxiliary tool for wearing elastic stockings. Compared with the prior art, it has the following advantages:

[0014] (1) The auxiliary elastic stocking wearing tool uses an electric push rod to drive the Z-shaped pull rod to move down along the side support, pushing the left and right edges of the elastic stockings to the sides and supporting them downwards. This greatly reduces the difficulty of putting on the stockings on the frame, effectively avoiding the tedious operation of manually putting on the elastic stockings. It saves time and effort and is especially suitable for obese, long-term bedridden, weak and elderly patients who have difficulty wearing the stockings themselves. It improves the patient's wearing compliance and ensures the standardized wearing of the elastic stockings with the assistance of the main expansion frame.

[0015] (2) The auxiliary elastic stocking wearing tool automatically extracts and sprays the medicine in the supply bottle during the wearing process through the linkage of the pull bar and the spray piston. This allows the auxiliary treatment medicine to be evenly covered and penetrated on the surface of the elastic stocking through the L-shaped spray channel. This ensures the uniformity of the medicine's effect and eliminates the need for additional manual application steps. It simplifies the wearing and treatment process of the auxiliary wearing structure and improves the use effect and treatment assistance of the elastic stocking. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 An assistive tool for wearing elastic stockings, comprising:

[0023] The auxiliary wearable structure 1 is integrally welded together from a main expansion frame 11, a rear support frame 111, and side supports 12. The main expansion frame 11 has an inclined semi-annular open sleeve. U-shaped side supports 12 and double L-shaped rear supports 111 are welded to the surface of its lower C-shaped base frame on the left, right, and rear sides, respectively. The side supports 12 are vertically arranged on both sides of the main expansion frame 11, and the rear supports 111 are parallel to the rear side of the main expansion frame 11. Both the side supports 12 and the rear supports 111 are inclined at the same angle as the main expansion frame 11. On the pole of the side bracket 12 near the main expansion frame 11, an electrical socket 121 is installed on the upper side of the main expansion frame 11 using bolts and plastic clips. The lower side of the electrical socket 121 has a power inlet. The electric push rod 13 is pushed parallel to the pole of the side bracket 12 to make electrical connection with the electrical socket 121. The output rod of the electric push rod 13 has a screw hole that opens to the end face. The screw hole is threaded to the Z-shaped pull rod 131. The pull rod 131 is parallel to the main expansion frame 11 in its final position after connection. On both sides of the main expansion frame 11, and between the pull rod 131 and the main expansion frame 11, space is reserved to allow elastic stockings to be placed and moved on the main expansion frame 11. On the side of the electric actuator 13 near the main expansion frame 11, a medicine tube 14 is connected parallel to the support rod. A supply bottle 141 is threadedly installed at the connection port of the upper end of the medicine tube 14. Both the port connecting the supply bottle 141 to the medicine tube 14 and the input port at the opposite end of the medicine tube 14 are equipped with one-way valves, thereby allowing the auxiliary fluid inside the supply bottle 141 to flow smoothly. The therapeutic agent can be unidirectionally introduced into the drug tube 14. The inside of the drug tube 14 is equipped with a spray piston 142 that moves back and forth along the inner wall. One end of the spray piston 142 extends out of the drug tube 14 to the pull rod 131 and is vertically connected to the pull rod 131 in a shape fit. The inside of the spray piston 142 has an L-shaped spray channel 143 that runs through the piston end to the end connected to the pull rod 131 along the axis. A nozzle for spraying the agent is installed at the open port near the pull rod 131.

[0024] During operation, the elastic stockings are first slipped onto the top of the semi-circular open sleeve of the main expansion frame 11, with the lower end of the pull rod 131 resting against the stocking opening. The elastic stockings hang naturally and fit snugly against the sleeve. Simultaneously, medication is loaded into the supply bottle 141. The electric actuator 13 is pushed up to connect with the electrical socket 121 to power on the device. After starting the device, the electric actuator 13 drives the Z-shaped pull rod 131 downward, pushing the edge of the elastic stockings downward to the sides for support, saving time and effort. During this process, the pull rod 131 drags the spray piston 142, creating negative pressure in the medication tube 14 to allow the medication to enter. After the patient's foot is inserted from the open end to complete the wearing process, the electric actuator 13 reverses its direction, the pull rod 131 resets and releases the top support, the spray piston 142 is pushed back, and the medication is sprayed out from the nozzle through the L-shaped spray channel 143, covering the elastic stockings. The patient pulls out their leg, and the elastic stockings tighten elastically to fit the leg, completing the wearing process.

[0025] In summary, by using the electric push rod 13 to move the Z-shaped pull rod 131 down along the side support 12, the left and right edges of the elastic stockings are pushed down to the sides, greatly reducing the difficulty of putting them on the frame. This effectively avoids the tedious manual operation of putting on elastic stockings, saving time and effort. It is especially suitable for obese, bedridden, weak, and elderly patients who have difficulty putting on their own, improving patient compliance and ensuring that the elastic stockings are worn correctly with the assistance of the main expansion frame 11. Through the linkage between the pull rod 131 and the spray piston 142, the extraction and spraying of the medicine in the supply bottle 141 are automatically completed during the wearing process. This allows the auxiliary treatment medicine to be evenly covered and penetrated onto the surface of the elastic stockings through the L-shaped spray channel 143 from the nozzle. This ensures the uniformity of the medicine's effect and eliminates the need for additional manual application steps, simplifying the wearing and treatment process on the auxiliary wearing structure 1 and improving the effectiveness and therapeutic assistance of the elastic stockings.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: During operation, firstly, the wearing end of the elastic stocking is slipped onto the top of the semi-circular open sleeve frame of the main expansion frame 11, and the lower end of the pull rod 131 is supported at the stocking opening. At this time, the main body of the elastic stocking will naturally fall into the sleeve frame and conform to the surface of the sleeve frame. Simultaneously, auxiliary therapeutic agents are loaded into the supply bottle 141. The electric push rod 13 is pushed up along the side support 12 and connected to the socket 121 to complete the circuit connection. After the equipment is started, the electric push rod 13 is energized and drives the Z-shaped pull rod 131 to move down along the side support 12, pushing the left and right edges of the elastic stocking downwards and supporting them to both sides. This not only reduces the difficulty of putting on the sleeve frame, but also avoids the trouble of manually putting on the elastic stocking, saving time and effort. During this process, the pull rod 131... The spray piston 142 is moved synchronously along the inner wall of the medicine tube 14, creating a negative pressure inside the medicine tube 14, which opens the one-way valve in the supply bottle 141, allowing the medicine to enter the medicine tube 14. Then, the patient inserts their foot into the open end of the elastic stocking supported by the main expansion frame 11 and moves it downward to complete the wearing process. After wearing, the electric push rod 13 is activated in the reverse direction, driving the pull rod 131 to release the top support of the elastic stocking opening. During the reverse movement and reset process, the spray piston 142 is pushed into the medicine tube 14 in the reverse direction. The medicine is pressurized and sprayed out from the nozzle through the L-shaped spray channel 143, evenly covering and penetrating the surface of the elastic stocking. Then, the patient can pull their leg out of the main expansion frame 11. At this time, the elastic stocking tightens and fits the leg under its own elasticity, completing the wearing process.
