Description

A lower limb traction bed

Technical Field

The utility model relates to the technical field of medical traction beds, in particular to a lower limb traction bed.

Background Art

There are many equipments needed for orthopedic surgery, and traction bed is one of them. At the same time, traction bed is also a new type of rehabilitation treatment machine suitable for individuals to perform self-traction treatment, muscle relaxation and self-exercise at home, work and other places. When a person's leg is fractured, the leg needs to be pulled by a traction bed to pull the spasmodic muscles, allow the bones to grow normally and avoid deformity healing.

For example, a Chinese utility model patent (CN217066722U) discloses a traction bed for lower limb fractures, which records: "A pulley is fixedly connected to the left end of the bed frame, a steel wire rope is provided on the outer sleeve of the pulley, an L-shaped plate is fixedly connected to the right end of the steel wire rope, and a tray is fixedly connected to the lower end of the steel wire rope. The pulley, steel wire rope, L-shaped plate and tray are arranged to form a traction mechanism of the traction bed. The patient's feet are fixed on the L-shaped plate, and then a heavy object is placed on the tray. The traction direction of the steel wire rope is changed by the pulley, thereby traction is performed on the patient's legs." It also records: "When traction beds currently used in hospitals are used to traction patients' legs, heavy objects are needed to traction them. Since the friction between the clothes worn by the patient and the bed sheets is small, the patient's body will move to the foot of the bed with the traction. When the patient's feet come into contact with the guardrail or the traction heavy object comes into contact with the ground, the traction effect on the patient's legs will be lost, thereby losing the traction effect." This is a technical problem.

Based on the above, it can be seen that the following technical problems exist in the prior art: the traction bed currently used in hospitals needs to be equipped with heavy objects to pull the patient's legs.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

As described in the background technology, the traction beds currently used in hospitals need to be equipped with weights to pull the patient's legs. Since the friction between the patient's clothes and the bed sheets is relatively small, the patient's body will move toward the foot of the bed during traction. When the patient's feet come into contact with the guardrail or the weight being pulled comes into contact with the ground, the traction effect on the patient's legs will be lost, thereby losing the traction effect.

In order to solve this technical problem, the utility model provides a lower limb traction bed, which is used for lower limb traction.

Specifically, please refer to Figures 1 to 7, the lower limb traction bed specifically includes:

A bed frame 1, a bed body 2 is fixed on the bed frame 1, two top plates 7 are movably connected to the middle of the upper end of the bed body 2, and a top plate 2 8 is rotatably connected to the side of the two top plates 7 close to each other, a lifting mechanism 6 is arranged below the bed body 2 and at a position corresponding to the top plate 2 8, and guardrail mechanisms 9 are arranged on both sides of the bed body 2;

The traction plate 3 is arranged above one end of the bed body 2 , the traction plate 3 is movably connected to the bed body 2 , a fixing mechanism 4 is arranged above the traction plate 3 , and a traction mechanism 5 is arranged at one end of the traction plate 3 .

The lower limb traction bed provided by the utility model can realize, through the structural design of the lifting mechanism 6, that in the process of using the traction mechanism 5 to pull the patient's legs, the top plate 1 7 and the top plate 2 8 located below the patient's buttocks can be lifted up by the lifting mechanism 6 to block and support the patient's buttocks, thereby preventing the patient's body from sliding down due to the traction of the heavy object 13 and causing the traction to fail, thereby improving the traction effect.

In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

Example

Please refer to Figures 1 to 5, a lower limb traction bed includes: a bed frame 1, a bed body 2 is fixed above the bed frame 1, two top plates 7 are movably connected to the middle of the upper end of the bed body 2, a top plate 2 8 is rotatably connected to one side of the two top plates 7 close to each other, a lifting mechanism 6 is arranged below the bed body 2 and at a position corresponding to the top plate 2 8, and guardrail mechanisms 9 are arranged on both sides of the bed body 2.

Furthermore, the lifting mechanism 6 includes a top block 14, the upper end of the top block 14 is fixedly connected to the lower end of the top plate 28, and two connecting rods 15 are rotatably connected to the two sides of the top block 14 respectively, and the ends of the two connecting rods 15 away from the top block 14 are rotatably connected to the rotating seat 16 and the threaded seat 17 respectively, and a fixed seat 18 is also provided below the top block 14, and the lower end of the fixed seat 18 is fixedly connected to the bed frame 1, and two connecting rods 2 19 are rotatably connected to the two sides of the fixed seat 18, and the ends of the two connecting rods 2 19 away from the fixed seat 18 are rotatably connected to the rotating seat 16 and the threaded seat 17 respectively, and a threaded rod 20 is also provided between the rotating seat 16 and the threaded seat 17, one end of the threaded rod 20 is threadedly connected to the threaded seat 17, and the end of the threaded rod 20 away from the threaded seat 17 is rotatably connected to the rotating seat 16, and a rotating head 21 is fixedly connected to one end of the threaded rod 20 and at a position close to the rotating seat 16.

It can be seen that during the traction process, the rotating head 21 can be rotated to drive the threaded rod 20 to rotate. The threaded seat 17 threadedly connected to the threaded rod 20 will approach each other with the rotating seat 16 under the action of the threaded rod 20, so that the top block 14 is gradually lifted upward, driving the top plate 28 and the top plate 7 to push upward, thereby blocking and supporting the patient's buttocks, preventing the patient's body from sliding down during the traction process and causing the traction to fail, thereby improving the traction effect.

The traction plate 3 is arranged above one end of the bed body 2, and the traction plate 3 is movably connected to the bed body 2. A fixing mechanism 4 is arranged above the traction plate 3 for fixing the patient's foot to the traction plate 3; further, the fixing mechanism 4 includes a column 1 22, and the column 1 22 is fixedly connected to the traction plate 3. The upper end of the column 1 22 is rotatably connected to the limiting arm 23, and a column 24 is arranged below the end of the limiting arm 23 away from the column 1 22, and the column 24 is fixedly connected to the traction plate 3. A threaded rod 26 is fixedly connected to the side, and the threaded rod 26 is movably connected to the limit arm 23. An opening rotary piece 25 is rotatably connected to the upper part of the limit arm 23 and at the outer side of the threaded rod 26. The opening rotary piece 25 is buckled and connected to the threaded rod 26. A knob 27 is sleeved on the outer side of the threaded rod 26 and at the position above the opening rotary piece 25. The knob 27 is threadedly connected to the threaded rod 26. Furthermore, in order to better fit the patient's foot, a rubber block 28 is rotatably connected to the inner side of the middle part of the limit arm 23.

Specifically, a traction mechanism 5 is provided at one end of the traction plate 3; further, the traction mechanism 5 includes a gear plate 11, which is rotatably connected to the bed frame 1, and the outer movably connected to the gear plate 11 is a chain 12, one end of the chain 12 is fixedly connected to the traction plate 3, and the lower end of the chain 12 is fixedly connected to a weight 13.

It can be seen that when the patient's lower limbs need to be pulled, the patient's feet can be placed above the traction plate 3 and between the column 1 22 and the column 24, and the limit arm 23 is rotated to make the rubber block 28 fit the patient's foot, and then the opening rotary piece 25 is rotated to make the opening rotary piece 25 engage with the threaded rod 26, and then the threaded rod 26 is rotated to press the opening rotary piece 25, thereby completing the fixation of the patient's foot and the traction plate 3. At this time, the traction plate 3 will be under the action of the weight 13, and the traction direction of the chain 12 will be changed through the toothed disc 11, thereby pulling the patient's lower limbs.

Example

The lower limb traction bed provided in Example 1 is further optimized. Specifically, as shown in Figures 6 and 7, in order to facilitate the patient to sit up and lie down more easily, guardrail mechanisms 9 are provided on both sides of the bed body 2, and the guardrail mechanisms 9 include armrests 29. A plurality of connecting rods 30 are provided below the armrests 29. One end of the connecting rod 30 is rotatably connected to the bed body 2, and the end of the connecting rod 30 away from the bed body 2 is rotatably connected to the armrest 29. A connector 31 is fixedly connected below one end of the armrest 29, and a pressing block 33 is slidably connected inside the connector 31. A spring 34 is provided above the pressing block 33, and the spring 34 is fixedly connected to the armrest 29. A boss 35 is fixedly connected to the lower end of the pressing block 33, and a slope block 32 is provided on the outer side of the boss 35, and the slope block 32 is fixedly connected to the connecting rod 30.

It can be seen that through the above-mentioned structural design, the pressing block 33 can be pressed upward when the patient does not need to use it, thereby driving the boss 35 to move upward and separate from the slope block 32, so that the armrest 29 loses its support point and can be folded and retracted, thereby reducing the space occupied and improving the practicality of the device.

Example

The lower limb traction bed provided in Example 1 is further optimized. Specifically, as shown in FIG. 1 , in order to facilitate the movement of the device, moving wheels 10 are fixed at the four end corners below the bed frame 1 .
