Description

Technical Field

[0001] The utility model relates to the technical field of spinal traction, in particular to a spinal traction bed. Background Art

[0002] As society continues to develop, office workers, truck drivers, taxi drivers, and teachers, among others, often suffer from spinal injuries due to prolonged sedentary life and a lack of effective exercise. Lumbar injuries also pose a long-term threat to the lives of many motor vehicle drivers. The spine is divided into the cervical, thoracic, lumbar, sacral, and coccygeal regions. Traction is an effective treatment for spinal curvature and deformity.

[0003] There are already some spinal traction beds in the prior art, such as the Chinese invention patent with application number CN202310414647.8, entitled "A Multifunctional Spinal Traction Bed". The bed frame is divided into three parts: the head, the back, and the legs. The traction system uses three rotating motors and four electric cylinders to realize up-and-down and rotational traction of the cervical spine, up-and-down and rotational traction of the lumbar spine, and stretching traction of the spine, which greatly improves the treatment effect and reduces manpower consumption. However, the number of motors and cylinders is large, the cost is high, and the structure is relatively complex.

[0004] Another example is the Chinese utility model patent application number CN202021107682.3, titled "A Spinal Repositioning Traction Bed." A hydraulic telescopic rod extends the housing to the ground, pulling out the support block for increased stability. The output end of the electric telescopic rod drives the connecting ring through the connecting seat, driving the insulation belt to traction and reposition the patient's spine. However, this patent primarily addresses the problem of traction beds with a single support structure, poor stability, and prone to displacement and even rollover.

[0005] Another example is the Chinese invention patent application number CN201910051457.8, titled "A Spinal Traction Bed for Orthopedic Patients." This device can stretch and traction the patient's spine, while also providing rolling massage on the massage rollers. This improves treatment effectiveness and facilitates the recovery of spinal patients. The bed's angle can also be adjusted to suit the needs of different patients, making it easier to choose and use. However, the device requires manual rotation of the handle to drive the take-up turntable, which is labor-intensive and provides limited support for the shoulders and waist. Utility Model Content
