Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a portable supine cervical traction machine with adjustable angle. Background Art

[0002] Cervical spondylosis is a degenerative disease. In traditional concepts, it is more common among middle-aged and elderly people. However, with the development of society, the progress of the times, and the widespread coverage of "intelligent" life, people are "inseparable" from various electronic products in their daily lives, which has led to a trend of younger cervical spondylosis in the current society. There are mainly physical therapy, drug therapy, and surgical treatment for the treatment of cervical spondylosis. According to relevant academic research, physical therapy, including traction therapy, massage therapy, and acupuncture therapy; among them, traction therapy is currently a commonly used and effective method for the treatment of cervical spondylosis. Its purpose is to relieve neck muscle spasms, relax muscles, and relieve pain; enlarge the intervertebral foramen, relieve stimulation and compression of nerve roots; widen the intervertebral space, reduce pressure in the intervertebral disc, etc. At present, the more common traction devices in hospitals or clinics are mostly sit-and-stand type. Although this type of traction device is simple to operate, its treatment effect is closely related to the patient's sitting posture. In addition, because the human body is in a sitting state, the head is affected by gravity, which will offset part of the traction force, reducing the traction effect. At the same time, due to the different body shapes, body shapes, sitting postures and other factors of the patients, different patients and different tractions of the same patient often have different traction angles. The angle of the sit-and-stand device cannot be adjusted individually. This difference in angle may even cause symptoms to worsen after traction in some patients with more serious cervical spondylosis, increasing the risk of injury. The existing sit-and-stand devices often require the traditional method of increasing the number of weights to meet the doctor's requirements when setting the traction force, and the degree of automation is not high. To achieve a good traction effect, it is necessary to understand the patient's cervical spine condition through detection methods, and use appropriate traction angles and traction strengths under the doctor's advice.

[0054] This embodiment is different from the traditional traction equipment, and uses weights or winches to achieve the regulation of traction. In this embodiment, an electric push rod 91 that can realize wireless remote control is provided. The patient can lie on the machine and hold the wireless remote control to operate and find the traction force that suits him / her. At the same time, the traction force is displayed in real time through the digital dynamometer 51. This embodiment provides a method for adjusting the angle, which mainly consists of two parts: coarse adjustment and fine adjustment. The coarse adjustment part is realized by the adjustable headrest structure 7, and the fine adjustment part is realized by the adjustment structure 3.

[0055] Before traction, the patient needs to lift the headrest bracket 74 to a suitable position, and then drag the support plate 72 to automatically fall into the positioning groove 711 of the headrest base 71, and the slider 73 moves with the support plate 72. When the headrest bracket 74 is lifted to the maximum angle, the support plate 72 is also dragged to the most inward position, and the pin 725 of the support plate 72 will automatically slide to the horizontal groove of the slider 73 and enter the inclined groove during the movement. Then, the headrest bracket 74 is slightly pressed down, and the slider 73 slides in the opposite direction in the guide groove 713. The arc-shaped concave position 741 of the headrest bracket 74 is level with the plane of the base 1. This process is mainly suitable for providing a suitable traction position for the patient through rough adjustment before starting treatment.

[0056] In order to further control the precise traction angle, it is necessary to rotate the rotatable support tube 2 to a certain angle. At this time, by observing the first angle 101 formed between the wire rope 4 and the angle ruler 8, further, lift the adjustment screw 32 down and place the fixing nut in the fixing groove 37 of the top fixing bracket 31 of the base 1, and further, turn the hand wheel part of the adjustment screw 32 right until it fits with the front side of the top fixing bracket 31 of the base 1 to fix it. After relative stability, using the principle of equal internal angles of a triangle, the second angle 102 between the center of the patient's neck and the horizontal is equal to the first angle 101 between the wire rope 4 and the angle ruler 8.

[0057] When the patient needs to be treated in a flexed position at a larger angle, the adjustable belt 65 can be used to achieve contraction. Furthermore, the fabric at the occipital support belt 62 tends to be tightened, which can better fit the patient's occipital muscles. Conversely, when the patient needs to use a smaller and approximately parallel angle of traction, the adjustable belt 65 can be prevented from loosening.

[0058] In order to further accurately, stably and reliably control the traction force, the electric push rod 91 uses a wireless remote control to operate the telescopic movement. The patient can focus on his own comfort and operate the handheld wireless remote control to choose to stop and move at will. There is no need for the traditional cumbersome operation of relying on doctors to use manual traction or winch weights. To a certain extent, the patient's autonomous control is achieved, which further improves the treatment effect.

[0059] The cervical traction machine of this embodiment can be directly unfolded and placed on the bed surface for use. Before using the traction machine, the patient generally needs to be diagnosed by a professional doctor about the basic condition of the cervical vertebrae damage, and the doctor gives the recommended traction angle and strength before directly using the traction machine.

[0060] Before implementation, the adjustable headrest structure 7 needs to be adjusted. This part of the device mainly replaces the traditional operation of using different numbers of pillows to raise the height and find a suitable height to meet the next traction action. If the patient's forward flexion angle is large, the headrest bracket 74 needs to be lifted up so that its inclined surface forms a larger angle with the horizontal plane; if it is necessary to return to adjust the angle of the headrest bracket 74, continue to raise the headrest bracket 74, at this time the support plate 72 follows and drags, thereby driving the slider 73 to move in the guide groove 713; then lowering the headrest bracket 74 can reset its initial horizontal position, and the angle of the headrest bracket 74 can be determined by reselecting the upper slot 731 of the headrest base 71.

[0061] After completing the above-mentioned rough adjustment, according to the doctor's advice, turn the rotatable support tube 2 to a suitable angle, observe the angle between the wire rope 4 and the angle ruler 8 to further fine-tune the angle of the rotatable support tube 2, lower the adjusting screw 32, and ensure that the fastening nut 33 on the adjusting screw 32 is placed in the fixing groove 37 at the top part of the base 1, then turn the adjusting screw 32 to the right until it fits tightly with the outer surface of the through hole 36 of the fixed bracket 31. At this time, the rotatable support tube 2 should not shake.

[0062] After completing the above two steps, the patient can wear the adjustable occipital-jaw strap 6 and place the head on the headrest support 74 of the adjustable headrest structure 7 support. At this time, the patient can feel whether the wrapping of the adjustable occipital-jaw strap 6 fits the back of the neck and the chin, and can operate the adjustable strap 65 to tighten or loosen the entire occipital-jaw strap. Finally, the Velcro 63 is adhered to the mandibular position support part 67 in the middle of the occipital-jaw strap body 61.

[0063] In this implementation case, in order to achieve accurate and controllable traction force and further improve the effectiveness of the treatment process, an automatic electric control system is used. When implementing traction, the patient can use a wireless remote control to accurately control the extension and retraction of the electric push rod 91, and the steel wire rope 4 fixed thereto is retracted by the recovery of the electric push rod 91, further providing a strong traction force for the adjustable occipital-chin strap 6. At the same time, the digital dynamometer 51 can display the current traction force in real time. Since the patient can independently control the traction force, he can accurately grasp his own comfort, greatly improving the traction effect.

[0064] The above detailed description is a specific description of a feasible embodiment of the present invention. The embodiment is not intended to limit the patent scope of the present invention. Any equivalent implementation or modification that does not deviate from the present invention should be included in the patent scope of this case.
