[0024] Reference Figures 1-4A lumbar traction therapy bed includes a bed frame 1, with a mattress 102 fixedly mounted on the top of the bed frame 1. It also includes a lower limb traction frame 202 and an upper limb traction frame 301 slidably mounted at both ends of the bed frame 1. A first restraint strap is detachably mounted on the lower limb traction frame 202 to secure the patient's waist, and a second and third restraint strap are detachably mounted on the upper limb traction frame 301 to secure the patient's chest and head, respectively, facilitating lumbar traction therapy. A bidirectional screw 4 is rotatably mounted inside the bed frame 1, threadedly connecting the lower limb traction frame 202 and the upper limb traction frame 301 to the bidirectional screw 4. A servo motor for driving the bidirectional screw 4 is fixedly mounted on the bed frame 1. A first gear 401 is fixedly mounted on the bidirectional screw 4, and a second gear 402 is fixedly mounted at the output end of the servo motor, meshing with it. A handle for controlling the servo motor is also fixedly mounted on the bed frame 1. The handle is existing technology and is used for control... The control of the servo motor's speed, direction of rotation, and working time facilitates automatic control. During use, starting the servo motor drives the bidirectional screw 4 to rotate, achieving not only uniform traction and traction maintenance, but also reciprocating traction by controlling the servo motor's direction of rotation, reducing the workload of staff and improving usability. Furthermore, an armrest 101 is fixedly installed on the bed 1 for the patient to place their arm. An emergency button is fixed at one end of the armrest 101; in case of an emergency, pressing the emergency button will stop the servo motor, improving safety. A display screen 503 for playing videos and music is mounted on a telescopic frame on the bed 1, with the screen fixed at one end. During use, the telescopic frame holds the display screen 503 above the patient's head, allowing them to watch videos while waiting for treatment, helping to distract them and improve the user experience.

[0025] Reference Figure 3 and Figure 4 A guide groove 103 is provided inside the bed body 1. A bidirectional screw 4 is rotatably set in the guide groove 103. A first adjusting cylinder 2 and a second adjusting cylinder 3 are slidably set at both ends of the guide groove 103. One end of the first adjusting cylinder 2 and the second adjusting cylinder 3 are threadedly connected to both ends of the bidirectional screw 4. An upper limb traction frame 301 is fixedly set at the other end of the second adjusting cylinder 3, and a lower limb traction frame 202 is set at the other end of the first adjusting cylinder 2. In use, by providing a guide groove 103 on the bed body 1, the first adjusting cylinder 2 and the second adjusting cylinder 3 can be reliably slid, thereby driving the lower limb traction frame 202 and the upper limb traction frame 301 to perform traction, improving the usage effect.

[0026] Reference Figure 3An adjusting rod 201 is slidably disposed within the first adjusting cylinder 2. The lower limb traction frame 202 is fixedly disposed at one end of the adjusting rod 201 extending out of the first adjusting cylinder 2. An insertion hole is provided at the other end of the first adjusting cylinder 2. Multiple through holes are equally spaced on the adjusting rod 201, with two to twenty sets of through holes, preferably twelve sets. A pin is slidably disposed within the insertion hole and extends into one of the through holes. In use, the lower limb traction frame 202 is fixed to the adjusting rod 201 by sliding the adjusting rod 201 within the first adjusting cylinder 2, which facilitates adjustment of the distance between the lower limb traction frame 202 and the mattress 102, enabling patients of different heights to use the device and increasing its usability.

[0027] Reference Figure 2 and Figure 3 Here, the telescopic frame is designed with a fixed cylinder 5 fixedly installed on the bed 1, and a telescopic rod 501 slidably installed inside the fixed cylinder 5. An adjusting screw for limiting the sliding of the telescopic rod 501 is threaded onto the fixed cylinder 5. An L-shaped fixed rod 502 is rotatably installed at one end of the telescopic rod 501 that extends out of the fixed cylinder 5. The housing of the display screen 503 is fixedly installed at the end of the fixed rod 502 away from the telescopic rod 501. The L-shaped fixed rod 502 can extend the display screen 503 above the patient's head for easy viewing. A limiting component is provided on the telescopic rod 501 to limit the rotation of the fixed rod 502. In use, by sliding the telescopic rod 501 inside the fixed cylinder 5, the height of the display screen 503 can be easily adjusted. Rotating the fixed rod 502 onto the telescopic rod 501 can not only adjust the tilt angle of the display screen 503, but also push the fixed rod 502 and the display screen 503 to the upper limb traction frame 301 after use to avoid obstruction when the patient lies down or gets up, thus improving the user experience.

[0028] Reference Figure 2 Here, the limiting component includes a fixed plate fixedly mounted on the telescopic rod 501. The fixed plate is semi-circular, and the other end of the fixed rod 502 is rotatably mounted on the fixed plate. The rotation axis of the fixed rod 502 coincides with the axis of the fixed plate. An arc-shaped limiting groove 504 is provided on the fixed plate, and the center of the limiting groove 504 is on the axis of the fixed plate. A limiting block is slidably mounted in the limiting groove 504. The fixed rod 502 is fixedly connected to the limiting block by bolts. That is, the bolts pass through the fixed rod 502 and are threadedly connected to the limiting block, so as to fix the fixed rod 502 in the current position of the fixed plate. The adjustment is convenient and the fixation is reliable.
