Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to a lumbar disc herniation traction bed. Background Art

[0002] Lumbar disc herniation is a type of orthopedic disease, and there are many clinical treatment methods for this disease. Among them, conservative therapies are aimed at disc herniation caused by different degrees of tension in the bilateral lumbar muscles. For this cause, there are mainly two conservative treatment options: traction and massage. Traction mainly uses mechanical force to stretch the intervertebral space, thereby reducing the internal pressure of the intervertebral disc and slightly reducing the compression of the herniated mass on the nerve; massage targets the lumbar muscles, and through specific techniques, stimulates the bilateral lumbar muscles to reach the same tension, so as to correct the position of the spinal vertebrae and return the intervertebral disc to its original position.

[0003] Currently, the main traction tool is a traction bed, but generally, the traction bed only performs front-back traction and cannot perform rotational traction. Content of the Utility Model

[0004] Aiming at the above deficiencies, the purpose of the utility model is to provide a lumbar disc herniation traction bed to solve the problem of inability to perform rotational traction in the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A lumbar disc herniation traction bed includes a front bed and a rear bed. The bottom of the front bed is provided with support feet, the support feet are arranged on a bottom plate, the bottom plate is provided with support blocks for supporting the rear bed, a pushing mechanism is fixedly installed on the bottom plate, the pushing mechanism is movably connected to the rear bed, the support blocks are provided with a braking mechanism for braking the rear bed, the front bed is provided with a front fixing belt for fixing the head, and the rear bed is provided with a rear fixing mechanism for fixing the feet.

[0007] Through the above scheme, the traction bed can be tractioned back and forth through the pushing mechanism, and the traction bed can be rotationally tractioned through the braking mechanism. Through rotational traction, a certain negative pressure can be generated in the lumbar intervertebral disc, which helps the intervertebral disc to be reset and retracted, reduces the compression on the nerve root, and thus significantly improves the treatment effect. At the same time, rotational traction can also improve the tension and spasm state of the lumbar muscles, promote blood circulation in the waist, and accelerate the absorption and dissipation of inflammatory substances.

[0008] Further, an arc-shaped block is provided on the lower side of the rear bed, an arc-shaped groove is provided on the upper side of the support block, and the arc-shaped groove is adapted to the arc-shaped block.

[0009] Through the above further scheme, the arc-shaped block can perform left-right rotational sliding and front-back sliding in the arc-shaped groove.

[0010] Further, the braking mechanism includes a motor and a brake wheel. The motor is embedded in the supporting block, and the brake wheel is fixedly installed on the output shaft of the motor. The arc-shaped block is provided with a driven gear, and the driven gear is meshed and connected with the brake wheel.

[0011] Through the above further solution, the motor can drive the brake wheel to rotate. The brake wheel is meshed and connected with the driven gear to drive the arc-shaped block to rotate, thereby driving the rear bed to rotate and performing rotational traction on the traction bed.

[0012] Further, the pushing mechanism includes a cylinder and a slider. The slider is fixedly installed at the end of the output shaft of the cylinder. The cylinder is fixedly installed on the bottom plate through a support column. An arc-shaped chute is provided on the side of the arc-shaped block facing the cylinder, and the slider is slidably connected in the arc-shaped chute.

[0013] Through the above further solution, the cylinder can drive the slider to push forward, thereby pushing the arc-shaped block forward. It can not only adjust the distance between the front fixing belt and the rear fixing mechanism according to the patient's height, but also perform front and rear traction to treat the patient.

[0014] Further, the rear fixing mechanism includes a positioning rod, a fixing rod, a clamping rod, a sliding rod and a spring. The positioning rod is fixedly installed on the rear bed, the fixing rod is fixedly installed at the top of the positioning rod, a slide rail is provided on the positioning rod, a spring groove is provided below the slide rail in the positioning rod, the clamping rod is slidably connected in the slide rail, the sliding rod is arranged below the clamping rod, the sliding rod penetrates into the spring groove, and a spring is arranged in the spring groove. One end of the spring is fixedly connected to the bottom of the spring groove, and the other end is fixedly connected to the bottom of the sliding rod.

[0015] Through the above further solution, the ankle can be clamped by the clamping rod and the fixing rod for fixation. The spring applies pressure to the clamping rod, and the foot will not be fixed rigidly, which can avoid excessive tensile force and cause damage to the waist.

[0016] Further, the front fixing belt is slidably connected to the front bed, and a soft pad is provided on the front fixing belt.

[0017] Through the above further solution, the fixing belt fixes the head, and the soft pad can provide protection to avoid strangulation.

[0018] Further, an auxiliary block is provided on the bottom plate on one side of the supporting block. An arc groove is provided on the auxiliary block, and the auxiliary block corresponds to the supporting block in position.

[0019] Through the above further solution, the auxiliary block can support the rear bed, and the auxiliary block can prevent the rear bed from moving backward too far, thus affecting the stability of the rear bed.

[0020] Further, a restraint belt is also provided on the front bed.

[0021] Through the above further solution, the restraint belt further fixes the upper body of the patient, avoiding the upper body from rotating when the lower bed drives the lower body to rotate.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] 1. The motor drives the arc-shaped block to rotate, thereby driving the rear bed to rotate, and performing rotary traction on the traction bed, enabling precise traction and adjustment of the waist in multiple directions, thus more effectively relieving waist pressure and pain.

[0024] 2. The air cylinder drives the slider to push forward, thereby pushing the arc-shaped block forward. It can not only adjust the distance between the front fixing belt and the rear fixing mechanism according to the patient's height, but also perform front and rear traction to treat the patient.
