Technical Field
[0001] This utility model relates to the field of spinal traction rehabilitation bed technology, and more specifically, to a spinal traction rehabilitation bed that can improve comfort. Background Technology
[0002] In modern society, the fast-paced lifestyle, long-term poor posture, and accelerated aging have led to a year-on-year increase in the incidence of spinal diseases. Conditions such as lumbar disc herniation, cervical spondylosis, and scoliosis seriously interfere with patients' daily activities and greatly reduce their quality of life. Among the many treatment methods for spinal diseases, spinal traction is a basic and important therapy. By applying continuous and stable traction force to the spine, it can effectively open the intervertebral space, reduce the compression of the intervertebral disc on the surrounding nerves and blood vessels, promote the restoration of the physiological curvature of the spine, thereby relieving pain, improving nerve function, and playing a key role in the recovery of the condition.
[0003] Chinese patent application CN202420955760.7 discloses a spinal traction rehabilitation bed that improves comfort. The bed includes a movable bed frame, straps, a soft pad, a controller placement box and controller connected to one side of the movable bed frame, and a rotating plate drive device and a moving plate drive device located at the bottom of the movable bed frame. This invention achieves effective traction exercises for the lumbar spine through the rotation and stretching of the rotating plate and the movement and traction of the moving plate, thereby strengthening the lumbar region, relieving lumbar muscle tension, and preventing lumbar muscle strain. It replaces the existing method of traction using traction ropes, resulting in greater comfort for the patient during spinal rehabilitation training.
[0004] However, as can be seen from the accompanying drawings in the instruction manual, the bed board is moved directly by controlling the bolts with a motor, resulting in a rather stiff movement process. This makes it difficult to buffer the intensity of traction, and the structure cannot assist the patient in tilting their waist or even sitting up, thus affecting the effectiveness of use. Therefore, a spinal traction rehabilitation bed that can improve comfort is proposed. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a spinal traction rehabilitation bed that can improve comfort, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a spinal traction rehabilitation bed that improves comfort, comprising a bed frame, a fixed bed board on one side of the top of the bed frame, and a movable bed board on the other side of the top of the bed frame. By rotating the movable bed board on the side of the fixed bed board, the patient can easily sit up with their waist tilted. The top of both the movable bed board and the fixed bed board are provided with a first sponge pad, which improves the comfort of lying flat. A tension plate is embedded at one end of the top of the movable bed board, and a second sponge pad is provided on the top of the tension plate. A position locking mechanism is provided at the bottom of the tension plate, which facilitates traction and pull by horizontal movement of the tension plate, and improves the comfort of lying flat by the second sponge pad.
[0007] The movable bed board has first electric push rods symmetrically arranged on both sides of its bottom. A controller is connected to one side of the bed frame via a wire. Straps are symmetrically fixed to both sides of the tension plate and the movable bed board. A protective sleeve is fitted in the middle of the straps. Activating the first electric push rods controls the rotation of the movable bed board, which can easily adjust the tilt angle of the movable bed board. The controller can be used to control its operation. The straps and protective sleeves can be easily tied to the patient's chest for easy traction and use. The protective sleeves also provide cushioning and protection.
[0008] The surface of the movable bed board is provided with limiting sliding holes and limiting sliding grooves. A stabilizing rod is fixedly connected to the middle of each limiting sliding hole and limiting sliding groove. A limiting sliding plate and a limiting slider are fixedly connected to the bottom of the tension plate. A movable frame is sleeved in the middle of the stabilizing rod. A spring is provided in the middle of the movable frame. A second electric push rod is fixedly connected to the bottom of the movable bed board. A pressure sensor is connected to the moving end of the second electric push rod. Activating the second electric push rod moves the pressure sensor, which pushes the movable frame. This, in turn, compresses the spring, causing the limiting sliding plate to move, thus moving the tension plate. When the tension plate encounters significant resistance, the compression of the spring can act as a buffer. The pressure sensor allows for convenient real-time monitoring of the pressure, preventing excessive traction and secondary injuries.
[0009] Preferably, the fixed bed board and the movable bed board are rotatably connected on opposite sides by a pivot shaft, and the two ends of the first electric push rod are rotatably connected to the walls of the movable bed board and the bed frame, respectively. Activating the first electric push rod controls the rotation of the movable bed board, which facilitates tilting use.
[0010] Preferably, the limiting slide plate corresponds to the limiting slide hole, the limiting slide plate is disposed in the middle of the limiting slide hole, and the stabilizing rod in the middle of the limiting slide hole passes through the middle of the limiting slide plate. Through the cooperation of the limiting slide plate and the limiting slide hole, the stability of the stretching plate movement is improved.
[0011] Preferably, the limiting slider corresponds to the limiting groove, the limiting slider is disposed in the middle of the limiting groove, and the stabilizing rod in the middle of the limiting groove passes through the middle of the limiting slider. Through the cooperation of the limiting groove and the limiting slider, the stability of the stretching plate movement is further improved.
[0012] Preferably, the cross-sectional shape of the movable frame is set to "U" shape, the limiting slide is set in the middle of the movable frame, and there are two springs, which are respectively set on both sides of the limiting slide. When the movable frame moves, the springs can push the limiting slide, and the limiting slide can squeeze the springs to play a buffering role.
[0013] Preferably, the second electric push rod corresponds to the movable frame, and one side of the pressure sensor is fixed to one side of the movable frame. Starting the second electric push rod facilitates driving, and the pressure sensor facilitates the detection of pressure values, thereby detecting the traction strength and facilitating adjustment.
[0014] Preferably, the position locking mechanism includes an insertion hole on one side of the bottom of the tension plate, a rod is inserted into the top of the movable bed board at a position corresponding to the insertion hole, a lifting block is fixedly connected to the bottom of the rod, and a threaded rod is inserted into the side of the movable bed board at a position corresponding to the lifting block.
[0015] Preferably, one end of the threaded insert is fixedly connected to a rotating column, and the other end of the threaded insert is threadedly fitted with a threaded push block. The two side walls of the threaded push block are slidably connected to the cavity wall through a slide rail. A return spring is fitted at the lower end of the insert, and one end of the threaded push block is set as an inclined surface.
[0016] Preferably, the bottom of the lifting block corresponds to the inclined surface of one end of the threaded push block, and one end of the insertion rod extends into the interior of the insertion hole and is adapted to the inner cavity of the insertion hole. By rotating the rotating column to control the rotation of the threaded insertion rod, the threaded push block can be controlled to squeeze the lifting block, thereby causing the lifting block to move upward and squeeze the return spring, so that the top end of the lifting block extends into the interior of the insertion hole. By rotating the rotating column in the opposite direction to control the threaded push block to move away from the lifting block, the end of the insertion rod can be moved out of the interior of the insertion hole by the push of the return spring on the lifting block.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] 1. This utility model first activates the first electric push rod to control the rotation of the movable bed board, which facilitates the adjustment of the tilt angle of the movable bed board, thereby assisting the patient in tilting their waist or sitting up, making it convenient to use. Then, by activating the second electric push rod, the moving frame is moved, which pushes the tension plate in sequence to facilitate traction. The compression of the spring by the limiting slide plate can buffer the traction, allowing the traction intensity to increase slowly and improving the comfort of traction. The pressure sensor facilitates real-time detection of the traction intensity for easy control. The first and second sponge pads improve the patient's comfort when lying flat.
[0019] 2. This utility model also features straps that allow for easy binding to the patient's buttocks and chest, facilitating traction and use.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] As attached Figure 1-6 The spinal traction rehabilitation bed shown includes a bed frame 1, a fixed bed board 2 on one side of the top of the bed frame 1, and a movable bed board 3 on the other side of the top of the bed frame 1. The movable bed board 3 can rotate on the side of the fixed bed board 2, which can facilitate the patient to sit up with a tilted waist. The top of both the movable bed board 3 and the fixed bed board 2 is provided with a first sponge pad 4, which improves the comfort of lying flat. A tension plate 5 is embedded at one end of the top of the movable bed board 3. A second sponge pad 6 is provided on the top of the tension plate 5. A position locking mechanism is provided at the bottom of the tension plate 5. The horizontal movement of the tension plate 5 facilitates traction and pull, and the second sponge pad 6 improves the comfort of lying flat. The position locking mechanism can fix the tension plate 5 when not in use or when the patient is lying flat, preventing the tension plate 5 from moving and affecting the use effect.
[0030] The bottom sides of the movable bed board 3 are symmetrically equipped with first electric push rods 7. One side of the bed frame 1 is connected to a controller 8 via a wire. The tension plate 5 and the two sides of the movable bed board 3 are symmetrically fixed with straps 9. A protective sleeve 10 is fitted in the middle of the straps 9. Activating the first electric push rods 7 controls the rotation of the movable bed board 3, which can easily adjust the tilt angle of the movable bed board 3. It can be easily controlled by the controller 8. The straps 9 and the protective sleeve 10 can be easily tied to the patient's chest for easy traction and use. The protective sleeve 10 also plays a role in cushioning and protection.
[0031] The surface of the movable bed board 3 is provided with limiting sliding holes 11 and limiting sliding grooves 12. A stabilizing rod 15 is fixedly connected to the middle of both the limiting sliding holes 11 and the limiting sliding grooves 12. A limiting sliding plate 13 and a limiting slider 14 are fixedly connected to the bottom of the tension plate 5. A movable frame 16 is sleeved in the middle of the stabilizing rod 15. A spring 17 is provided in the middle of the movable frame 16. A second electric push rod 18 is fixedly connected to the bottom of the movable bed board 3. A pressure sensor 19 is connected to the moving end of the second electric push rod 18. Activating the second electric push rod 18 moves the pressure sensor 19, which can push the movable frame 16. This, in turn, compresses the spring 17, causing the limiting sliding plate 13 to move, thus moving the tension plate 5. When the tension plate 5 is subject to greater resistance, the compression of the spring 17 can act as a buffer. The pressure sensor 19 can be used to monitor the pressure in real time, preventing excessive traction and secondary injuries.
[0032] As attached Figure 1-5 As shown, the fixed bed board 2 and the movable bed board 3 are rotatably connected on opposite sides via a pivot. The two ends of the first electric push rod 7 are rotatably connected to the walls of the movable bed board 3 and the bed frame 1, respectively. The limiting slide plate 13 corresponds to the limiting slide hole 11 and is located in the middle of the limiting slide hole 11. The stabilizing rod 15 in the middle of the limiting slide hole 11 passes through the middle of the limiting slide plate 13. The limiting slider 14 corresponds to the limiting slide groove 12 and is located in the middle of the limiting slide groove 12. The stabilizing rod 15 in the middle of the limiting slide groove 12 passes through the middle of the limiting slider 14. The cross-sectional shape of the moving frame 16 is U-shaped. The limiting slide plate 13 is located in the middle of the moving frame 16. There are two springs 17, each located on the limiting slide plate 13. On both sides, the second electric push rod 18 corresponds to the movable frame 16. One side of the pressure sensor 19 is fixed to one side of the movable frame 16. Activating the first electric push rod 7 controls the rotation of the movable bed board 3, facilitating tilting. The cooperation of the limiting slide plate 13 and the limiting slide hole 11 improves the stability of the stretching plate 5 movement. The cooperation of the limiting slide groove 12 and the limiting slider 14 further improves the stability of the stretching plate 5 movement. As the movable frame 16 moves, the limiting slide plate 13 can be pushed by the spring 17, and the compression of the spring 17 by the limiting slide plate 13 provides a buffering effect. Activating the second electric push rod 18 facilitates driving, and the pressure sensor 19 facilitates the detection of pressure values, thereby detecting the traction strength and facilitating adjustment.
[0033] As attached Figure 1 , 5As shown in Figure 6, the position locking mechanism includes an insertion hole 26 on one side of the bottom of the tension plate 5. A rod 24 is inserted into the top of the movable bed plate 3 at a position corresponding to the insertion hole 26. A lifting block 23 is fixedly connected to the bottom of the rod 24. A threaded rod 20 is inserted into the side of the movable bed plate 3 at a position corresponding to the lifting block 23. A rotating column 21 is fixedly connected to one end of the threaded rod 20. A threaded push block 22 is threadedly fitted onto the other end of the threaded rod 20. The two side walls of the threaded push block 22 are slidably connected to the cavity wall via a slide rail. A return spring 25 is fitted onto the lower end of the rod 24. One end of the threaded push block 22 is set as an inclined surface. The bottom of the lifting block 23 corresponds to the inclined surface of one end of the threaded push block 22. One end of the insertion rod 24 extends into the interior of the insertion hole 26 and is adapted to the inner cavity of the insertion hole 26. By rotating the rotating column 21 to control the rotation of the threaded insertion rod 20, the threaded push block 22 can be controlled to press the lifting block 23, thereby causing the lifting block 23 to move upward to press the return spring 25, so that the top end of the lifting block 23 extends into the interior of the insertion hole 26. By rotating the rotating column 21 in the opposite direction to control the threaded push block 22 to move away from the lifting block 23, the push of the lifting block 23 by the return spring 25 can cause one end of the insertion rod 24 to move out of the interior of the insertion hole 26.
[0034] The working principle of this utility model is as follows: When in use, the patient platform is on the fixed bed board 2 and the movable bed board 3, and then tied to the patient's chest with the straps 9 to fix the patient's upper body. The protective sleeve 10 improves the cushioning effect of the binding. Then, the rotating column 21 is rotated to control the threaded push block 22 to move away from the lifting block 23. The lifting block 23 is pushed by the return spring 25, so that one end of the insertion rod 24 moves out from the inside of the insertion hole 26 to unlock the tension plate 5.
[0035] Then, the second electric push rod 18 is activated to control the movement of the stretching plate 5 in sequence, which can pull the patient's spine. At the same time, when the pulling resistance is large, the spring 17 can be squeezed by the limiting slide plate 13 to achieve a buffering effect. The pressure intensity is detected by the pressure sensor 19, which makes it easy to control the traction intensity, avoid excessive traction intensity and secondary injury to the patient, and improve the safety of traction.
[0036] The movable bed board 3 can be rotated by activating the first electric push rod 7, which can control the tilt of the patient's waist as needed, making it easy to adjust and use.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
