Technical Field

[0001] This application relates to the technical field of medical rehabilitation devices, and in particular to a cervical traction chair. Background Technology

[0002] Cervical spondylosis is a syndrome characterized by a series of clinical symptoms caused by degenerative changes in the cervical intervertebral discs and cervical osteophyte formation. Occupation is one of the contributing factors, especially for those who work at a desk for long periods, such as programmers, writers, and teachers. Furthermore, the high work pressure and overtime work in modern society further burden the cervical spine. The widespread use of smartphones also exacerbates this problem, as people spend their leisure time looking down at their devices, further straining the cervical spine and increasing the risk of cervical spondylosis.

[0003] Traction therapy is a common method in rehabilitation treatment, used to relieve muscle tension, improve joint mobility, and reduce pain. However, traditional traction devices are usually complex in structure, inconvenient to operate, and cannot visually display the traction force, making it difficult to meet the needs of different patients. Therefore, designing a traction chair that is simple in structure, easy to operate, and can display the traction force in real time is of significant practical importance. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a cervical traction chair. (Refer to...) Figure 1 The traction chair includes a chair body 1, a drive unit 2, a spring scale 4, a hanging frame 7, a controller 9, a traction rope 10, a seat cushion 11 and a backrest 12 on the chair body 1, and both the seat cushion 11 and the backrest 12 are covered with sponge to increase the user's comfort.

[0023] Reference Figure 2 , Figure 3 A vertical pole 3 is installed in the middle of the rear side of the chair body 1. A triangular support frame 5 is installed at the top of the vertical pole 3. A right rear fixed pulley 15 and a left rear fixed pulley 16 are respectively installed on the left and right sides of the triangular support frame 5 near the vertical pole 3. A telescopic rod 6 passes through the hollow of the triangular support frame 5. The telescopic rod 6 can move back and forth in the tripod 5. A handle set screw 17 is inserted in the triangular support frame 5 to fix its position. A right front fixed pulley 13 and a left front fixed pulley 14 are set at the front end of the telescopic rod 6 and guided by a traction rope 10. The traction rope 10 passes through the hanger 7, which includes a hanging box 701 and a movable pulley 705. A limit post 702 is set on the hanging box 701 to prevent the traction rope 10 from detaching. A protective plate 703 is fixed on the top of the hanging box 701 to prevent the traction rope 10 from rubbing against the hanging box 701. The protective plate 703 is made of plastic. Hanging rings are set on both sides of the lower part of the hanging box 701 for connecting the straps. The height of the suspension bracket 7 can be adjusted according to the patient's height.

[0024] Reference Figure 4 The drive unit 2 is installed at the bottom rear of the chair body 1. A wire 8 connects the controller 9 and the drive unit 2. The controller 9 can control the speed and traction direction of the drive unit 2. The drive unit 2 includes a motor 201. A fixing plate 101 is installed at the bottom of the chair body 1, and the motor 201 is mounted on the fixing plate 101. The motor 201 has a bidirectional rotating shaft, and a rotating wheel 202 is fixed to the left rotating shaft of the motor 201. One end of the traction rope 10 is fixed to the rotating wheel 202 and is wound by the forward and reverse rotation of the rotating wheel 202. The other end of the traction rope 10 is connected to a spring scale 4 through a winding hanger 7. The spring scale 4 is installed on the chair body 1 and displays the magnitude of the traction force. A protective sleeve 203 is fixed to the outside of the rotating wheel 202 to prevent the traction rope 10 from slipping off. A screw 204 is connected to the right side of the motor 201. A movable pin 206 is coupled to the screw 204. The movable pin 206 moves horizontally left and right as the motor 201 rotates forward and backward. Limit switches 1 205 and 207 are provided on the left and right ends of the fixed plate 101 to prevent the motor 201 from rotating too many times, so as to control the pulling distance of the traction rope 10.

[0025] The implementation principle of a cervical traction chair according to this application embodiment is as follows: During use, the user sits on the chair body 1, and the suspension frame 4 is fixed to the jaw position with straps as needed. The speed and traction direction of the motor 201 are adjusted by the controller 9. The motor 201 drives the traction rope 10 to pull the suspension frame 7, thereby achieving traction on the body parts. The spring scale 4 measures the tension on the traction rope 10 in real time. Medical staff and patients can adjust the traction intensity according to the displayed force to ensure the safety and effectiveness of traction treatment.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
