The inner wall of the neck support 17 is fixedly connected with a rubber ring 18, and the rubber ring 18 here improves the patient's comfort. The rear end of the backrest 3 is fixedly connected with an arm support 19, and the top of the arm support 19 is fixedly connected with two rubber pads 20. The shape of the rubber pad 20 is hemispherical. The arm support 19 here is used to place the patient's arm, and the two rubber pads 20 thereon are used to pad under the patient's elbow to prevent the olecranon bone from being sore due to sitting for a long time.
[0038] The front end of the backrest 3 is fixedly connected with a buffer component for supporting the patient's chest, and the buffer component includes a chest pillow 21. The rear end of the chest pillow 21 is fixedly connected to the front end of the backrest 3. The chest pillow 21 here can ensure that the patient has a support on the chest when lying on the backrest 3, and can effectively improve the patient's comfort when cooperating with the above-mentioned neck support 17 and arm support 19. The right side of the bottom box 22 is fixedly connected with an outer column 23, and the inner wall of the outer column 23 is fixedly connected with a motor 24. The driving end of the motor 24 is fixedly connected with a support rod 1 25, and the other end of the support rod 1 25 is rotatably connected to a support rod 2 26, and the other end of the support rod 2 26 is rotatably connected to the bottom end of the seat cushion 1. The four corners of the bottom end of the seat cushion 1 are fixedly connected with inner columns 27, the right side of the bottom box 22 is fixedly connected with an outer column 23, the inner wall of the outer column 23 is fixedly connected with a motor 24, and the driving end of the motor 24 is fixedly connected with a support rod 1 25. Starting the motor 24 here can drive the support rod 1 25 to rotate, and the other end of the support rod 1 25 is rotatably connected to the support rod 2 26, and the other end of the support rod 2 26 is rotatably connected to the bottom end of the seat cushion 1, and the support rod 1 25 here will drive the support rod 2 26 to rotate when rotating, thereby realizing the lifting of the seat cushion 1, and the four corners of the bottom end of the seat cushion 1 are fixedly connected with inner columns 27, and the multiple inner columns 27 here ensure the stability of the seat cushion 1 during lifting.
[0039] Working principle: First, the patient sits on the cushion 1 supported by multiple legs 2, with his back against the backrest 3. If the height of the backrest 3 needs to be adjusted, the patient or medical staff can pull the button 7 to make the slide column 5 disengage from the range of the slide slot 4, and then turn the button 7 to drive the main shaft 8 to move. The movement of the main shaft 8 will drive the gear 12 fixed thereon to rotate, and then drive the tooth plate 15 meshing with the gear 12 to move up and down. Since the tooth plate 15 is fixed on the inner plate 13, the inner plate 13 will also move up and down, thereby achieving the purpose of adjusting the height of the backrest 3. During the adjustment process, the design of the limit block 9 and the limit plate 14 can ensure that the main shaft 8 and the inner plate 13 will not disengage or slide out of the range of the backrest 3. At the same time, the design of the washer 10 and the spring 11 can ensure that the button 7 will not generate torque when rotating, thereby protecting the service life of the spring 11. After adjusting to the appropriate height, the patient can place the neck on the rubber ring 18 on the inner wall of the neck support 17, the arms on the two rubber pads 20 at the top of the arm support 19, and the chest on the chest pillow 21 to obtain the best comfort and support. Such a design can be adaptively adjusted according to the patient's height, so that the position of the chest puncture is accurate, the difficulty of operation is reduced, and thus the risk is reduced.
[0040] In addition to adjusting the backrest, this chair can also adjust the height of the legs 2 when necessary. At this time, the motor 24 on the inner wall of the outer column 23 can be started first. At this time, the motor 24 will drive the support rod 1 25 and the support rod 2 26 to rotate, thereby realizing the lifting and lowering of the seat cushion 1. The multiple inner columns 27 here ensure the stability of the seat cushion 1 during lifting and lowering to prevent deviation.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
