Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a special walking aid for patients undergoing hip replacement surgery. Background Technology
[0002] Hip replacement surgery is a mature surgical procedure that replaces a diseased hip joint with an implanted artificial prosthesis to restore joint function, relieve pain, and improve quality of life. When caring for hip replacement patients after surgery, they need to use assistive devices to help them move, improve the safety of the patient during movement, and enhance the patient's recovery.
[0003] In the current technology, when patients undergoing rehabilitation training for hip replacement, they use walking aids to move. In the early stages of training, patients mostly train indoors, where the floor is usually covered with a smooth floor. When patients make turning movements, they need to move around the walking aid as the center. However, the contact area at the bottom of the walking aid is small, and uneven force applied by the patient may cause tilting and slipping. This lack of stability may cause the patient to fall and get injured. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a special assistive nursing device for patients undergoing hip replacement surgery, thereby solving the problems mentioned in the background section.
[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:
[0006] This invention relates to a special assistive nursing device for patients undergoing hip replacement surgery, specifically comprising: an assistive frame, the assistive frame being a U-shaped structure composed of round tubes, with rotating wheels rotatably mounted at the top of both ends of the assistive frame; a fixed base cover mounted at the bottom of the assistive frame, and a guide groove provided on the side of the assistive frame; the bottom of the guide groove is connected to the inner side of the fixed base cover; a spring is mounted at the top of the inner side of the guide groove, and a guide rod is mounted on the inner side of the guide groove via the spring; the guide rod is a cylindrical structure, and a rubber suction cup is mounted at the bottom of the guide rod; the rubber suction cup is installed inside the fixed base cover.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Please refer to Figures 1 to 9 : Example 1: This invention proposes a special walking aid for patients undergoing hip replacement surgery, comprising: a walking frame 1, which is a U-shaped structure composed of round tubes, with rotating wheels 101 rotatably mounted at the top of both ends of the walking frame 1; the outer side of the rotating wheels 101 is provided with anti-slip threads, and a rotating threaded rod 102 is rotatably mounted at the middle position of the rotating wheels 101; a handrail 103 is mounted through the top of the walking frame 1 through the rotating threaded rod 102; two guide vertical rods 104 are mounted at the bottom of both ends of the handrail 103; the guide vertical rods 104 are cylindrical structures, and a connecting plate 105 is mounted through the top of the walking frame 1 at the bottom of the guide vertical rods 104; the bottom of the rotating threaded rod 102 is rotatably mounted at the middle position of the connecting plate 105.
[0024] In this embodiment of the invention, when a hip replacement patient undergoes rehabilitation training, the height of the handrail 103 is adjusted according to the patient's height and the support height. Rotating the rotating dial 101 at the top of both ends of the walking frame 1 drives the rotating threaded rod 102 to move, causing the top of the rotating threaded rod 102 to move the handrail 103 upwards. The handrail 103 then moves the guide rod 104 upwards, guiding the movement of the handrail 103. The connecting plate 105 prevents the guide rod 104 from moving too much. With the handrail 103 at a suitable height, it is convenient for the patient to support the handrail 103 during movement, improving patient comfort and rehabilitation effectiveness.
[0025] In Example 2, based on Example 1, a fixed base cover 2 is installed at the bottom of the walking frame 1, and a guide groove 201 is provided on the side of the walking frame 1; the bottom of the guide groove 201 is connected to the inner side of the fixed base cover 2; a spring is installed at the top of the inner side of the guide groove 201, and a guide rod 202 is installed on the inner side of the guide groove 201 through the spring; the guide rod 202 is a cylindrical structure, and a rubber suction cup 203 is installed at the bottom of the guide rod 202; the rubber suction cup 203 is installed inside the fixed base cover 2; a guide groove 204 is provided on the side of the guide rod 202, and an air hole 205 is opened at the bottom of the outer side of the guide rod 202; the interior of the air hole 205 is connected to the guide groove 204. The internal connections are as follows: A traction plate 206 is installed on the top of the guide slide rod 202; a spring is installed on the top inner side of the guide slide groove 204, and a guide slide rod 207 is installed inside the guide slide groove 204 via the spring; the bottom of the guide slide groove 204 is connected to the inside of the rubber suction cup 203; a traction plate 208 is installed on the top of the guide slide rod 207, and a sealing plug 209 is installed on the bottom of the guide slide rod 207; the outer side of the sealing plug 209 is made of rubber, and the sealing plug 209 is slidably installed inside the guide slide groove 204, and can slide downwards to be installed on the top of the rubber suction cup 203. When a hip replacement patient undergoes rehabilitation training, the inner side of the guide slide groove 204... The spring drives the guide slide rod 207 downwards, causing it to move the sealing plug 209 to block the top of the rubber suction cup 203, thus sealing the top of the rubber suction cup 203. After the fixed bottom cover 2 of the walking frame 1 is placed on the ground, the hand pushes the traction plate 206 downwards, causing the guide slide rod 202 to move downwards inside the guide groove 201. The guide slide rod 202 causes the bottom rubber suction cup 203 to adhere to the ground. The spring at the top of the guide slide rod 202 is a light spring, and its elastic force is less than the suction force of the rubber suction cup 203. The rubber suction cup 203 adheres to the ground, ensuring the stability of the walking frame 1 and facilitating the patient's movement around it, preventing tilting and slippage. To ensure the stability of the patient when turning, when the patient moves again with assistance, the hand pulls the traction plate 208 upward, causing the guide slide rod 207 to move upward inside the guide groove 204. The bottom of the guide slide rod 207 causes the sealing plug 209 to move away from the top of the rubber suction cup 203. The external airflow enters the bottom of the guide groove 204 through the air hole 205 and then enters the interior of the rubber suction cup 203, causing the rubber suction cup 203 to lose its negative pressure effect. Under the action of the spring, the guide slide rod 202 moves upward, causing the rubber suction cup 203 to retract to the top of the inner side of the fixed base cover 2. This does not affect the movement of the walking frame 1, making it easier for the patient to support the walking frame 1 for assisted movement and improving the patient's rehabilitation effect.
[0026] In Example 3, based on Example 1, positioning components 3 are installed at relatively opposite positions on the inner side of the walking frame 1; guide groove 1 301 and guide groove 2 302 are respectively opened at both ends of the inner side of the positioning component 3; guide block 1 303 is slidably installed inside guide groove 1 301; a support plate 304 is installed at the outer end of guide block 1 303; guide block 2 305 is installed at the outer end of support plate 304; guide block 2 305 is slidably installed inside guide groove 2 302; springs are installed at the top of the side ends of the two positioning components 3, and movable plates 306 are installed at the top of the side ends of the two positioning components 3 through the springs; positioning plates 307 are installed at both ends of the movable plate 306; the inner end of the positioning plate 307 penetrates the top of the positioning component 3 and is inserted into the interior of guide groove 1 301, and the inner end of the positioning plate 307 is located on the side of guide block 1 303. When the hip replacement patient is undergoing rehabilitation training, the patient supports the walking frame 1 to move, and the support plate 304... In a vertical position, it does not affect the patient's movement. When the patient needs to rest temporarily, the movable plate 306 moves upward, causing the positioning plate 307 to leave the guide groove 301, removing the obstruction to the movement of the guide block 303. The support plate 304 rotates around the guide block 303. The guide block 305 at the outer end of the support plate 304 rotates and is installed inside the guide groove 302. Pushing the support plate 304 backward causes the guide blocks 303 and 305 to move backward inside the guide grooves 301 and 302 respectively. Under the action of the spring, the positioning plate 307 moves downward to position the guide block 303, so that the support plate 304 is in a horizontal position, making it convenient for the patient to sit on the support plate 304 to rest. When not in use, the support plate 304 is in a vertical position. The support plate 304 is easy to switch between states, adapting to different usage scenarios and different patient needs.
[0027] The working principle of this embodiment is as follows: The height of the handrail 103 is adjusted according to the patient's height. Rotating the rotary dial 101 moves the rotary threaded rod 102, causing the top of the threaded rod 102 to move the handrail 103 upwards. The guide rod 104 guides the handrail 103, ensuring it is at a suitable height for the patient's movement. The spring inside the guide groove 204 moves the guide rod 207 downwards, sealing the top of the rubber suction cup 203 with the sealing plug 209. When the patient turns, the hand pushes the traction plate 206 downwards, causing the guide rod 202 to move downwards. The guide rod 202 causes the bottom rubber suction cup 203 to adhere to the ground, ensuring the stability of the walking frame 1. The patient turns using this as the center. When the patient moves again, the hand pulls the traction plate 208 upwards, causing the guide rod 207 to move upwards within the guide groove 204. The bottom of the guide rod 207 causes the sealing plug 209 to leave the rubber suction cup 203. At the top of 03, external airflow enters the bottom of guide groove 204 through air hole 205 and then enters the rubber suction cup 203. The rubber suction cup 203 loses its negative pressure effect and, under the action of the spring, drives guide rod 202 to move upward, causing the rubber suction cup 203 to retract to the top of the inner side of the fixed base cover 2. The patient supports the walking frame 1 for rehabilitation training. When the patient needs to rest temporarily, the moving plate 306 moves upward, driving the positioning plate 307 to remove the obstruction of guide block 303. The bearing seat plate 304 rotates around guide block 303, driving guide block 305 to rotate and install it in guide groove 2 302. Pushing the bearing seat plate 304 backward drives guide block 303 and guide block 305 to move backward in guide groove 1 301 and guide groove 2 302 respectively. Under the action of the spring, the positioning plate 307 moves downward to position guide block 303. The bearing seat plate 304 is in a horizontal position, making it convenient for the patient to sit on the bearing seat plate 304 to rest.
