Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and more specifically, to a head traction device. Background Art

[0002] The head traction device is a medical device that is usually used to treat cervical spine diseases or injuries. Its main function is to stretch the neck by applying a slight traction force to relieve the pressure on the cervical spine and promote the normal physiological state of the cervical spine. When in use, the patient's head is fixed on the traction device, and then a moderate traction force is applied by mechanical means, which helps to expand the space between the cervical vertebrae, reduce the pressure on the intervertebral disc, and improve the supply of nerves and blood.

[0003] Most of the existing head traction devices are driven by motors, but the human neck is relatively fragile, especially for patients with neck diseases. Their shoulders and necks are stiff, and even a slight correction will cause unbearable pain. Different people have different degrees of illness. Using motors to increase traction for correction is risky for cervical patients. The pulling force is difficult to control, and if you are not careful, you may easily use excessive force, causing discomfort, pain or worsening symptoms for the patient. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0028] Reference Figure 1-Figure 4 , a head traction device, comprising a support frame 1, a fixing plate 3 is fixedly connected to the top of the support frame 1, and a manual adjustment component is provided at the bottom of the fixing plate 3;

[0029] The manual adjustment component includes a traction wheel 4, which is rotatably connected to the fixed plate 3. A pull rope 7 is provided on the outer wall of the traction wheel 4, one end of the pull rope 7 is fixedly connected to the traction wheel 4, the end of the fixed plate 3 away from the traction wheel 4 is rotatably connected to the connecting wheel 8, and the end of the support frame 1 away from the fixed plate 3 is rotatably connected to the rotating wheel 9. The manual adjustment component also includes a connecting box 10, which is fixedly connected to the support frame 1, and the interior of the connecting box 10 is rotatably connected to a worm gear 15, which is coaxially arranged with the rotating wheel 9, and the interior of the connecting box 10 is rotatably connected to a worm 16.

[0030] By setting the manual adjustment device, the patient can manually control the traction force. Specifically, when the handle 17 rotates, the worm 16 is driven to rotate, and the rotation of the worm 16 drives the worm wheel 15 to rotate. The rotation of the worm wheel 15 drives the rotating wheel 9 to rotate, and then drives the traction wheel 4 to rotate. When the traction wheel 4 rotates, it can also drive the support belt 12 to move up and down. The patient manually controls the support belt 12 to pull the patient's head up and down. This autonomy can also reduce the risk of excessive traction and make treatment safer.

[0031] Reference Figure 1-Figure 4The worm 16 is meshed with the worm wheel 15 , and one end of the worm 16 extends through and extends to the outside of the connection box 10 and is fixedly connected to a rotating handle 17 .

[0032] The patient rotates the rotating handle 17 , which drives the worm 16 to rotate. The rotation of the worm 16 drives the worm wheel 15 to rotate, and further drives the rotating wheel 9 to rotate.

[0033] Reference Figure 1-Figure 4 The other end of the pull rope 7 is fixedly connected to the rotating wheel 9, and the pull rope 7 is sleeved on the outer walls of the connecting wheel 8 and the rotating wheel 9. An automatic adjustment component is provided on one side of the traction wheel 4. The automatic adjustment component includes a motor 5. The motor 5 is located on one side of the traction wheel 4 and is fixedly connected to the fixing plate 3. The shaft inside the traction wheel 4 is fixedly connected to the output end of the motor 5. A connecting rope 6 is provided on the outer wall of the traction wheel 4. One end of the connecting rope 6 is fixedly connected to the traction wheel 4, and the other end of the connecting rope 6 is fixedly connected to a placement rod 11.

[0034] By setting up the automatic adjustment component, the traction effect on the head can be achieved. Specifically, the motor 5 drives the traction wheel 4 to rotate, and when the traction wheel 4 rotates, it drives the support belt 12 under the connecting rope 6 to move up and down, and the traction force will be transmitted to the connecting rope 6. Finally, the rod 11 is placed to act on the head area to achieve traction on the head. It can be used for patients in the late stage of rehabilitation to help them restore normal neck function and enhance the stability of the cervical spine.

[0035] Reference Figure 1-Figure 4 A support belt 12 is provided at the bottom of the placement rod 11, hooks 13 are provided at both ends of the support belt 12, the support belt 12 is connected to the placement rod 11 through the two hooks 13, an airbag 14 is provided on the inner side of the support belt 12, and a seat 2 is provided on the front side of the support frame 1.

[0036] The support belt 12 can be firmly fixed to the patient's head area to ensure that the head will not shake or swing during traction treatment. The hook 13 is a prior art and can facilitate the replacement of the support belt 12. The airbag 14 can adjust its hardness and shape by inflation or deflation to adapt to the shape and size of the patient's head, thereby better fitting the head area.

[0037] Working principle: When in use, the head is first placed on the support belt 12, and the airbag 14 is inflated to make the support belt 12 fit the patient's head more closely. Then, if the patient is in the late stage of rehabilitation, the motor 5 drives the traction wheel 4 to rotate, driving the support belt 12 under the connecting rope 6 to move up and down, and the traction force is transmitted to the connecting rope 6. Finally, the rod 11 is placed to act on the head area to achieve traction treatment of the head.

[0038] If the patient is in the early stage of rehabilitation, he can manually turn the handle 17 according to the range he can bear, which drives the worm 16 to rotate, and the rotation of the worm 16 drives the worm wheel 15 to rotate, and the rotation of the worm wheel 15 drives the rotating wheel 9 to rotate, and the rotation of the rotating wheel 9 drives the pull rope 7 to tighten inward, thereby driving the traction wheel 4 to rotate. When the traction wheel 4 rotates, it can also drive the support belt 12 to move up and down. The patient manually controls the support belt 12 to pull the patient's head up and down. This autonomy can also reduce the risk of excessive traction and make treatment safer.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
