Description

Technical Field

[0001] The invention belongs to the technical field of orthopedic traction, and in particular relates to an orthopedic lumbar traction device. Background Art

[0002] Lumbar disc herniation is one of the common diseases. It is mainly caused by different degrees of degenerative changes in various parts of the lumbar disc. Under the influence of external factors, the annulus fibrosus ruptures and the nucleus pulposus protrudes from the rupture, causing the adjacent spinal nerve roots to be stimulated or compressed, resulting in a series of clinical symptoms such as low back pain, numbness and pain in one or both lower limbs. Among them, those with milder symptoms can be treated with traction. The goal of traction therapy is to improve the relationship between the protrusion and the nerves, relax the waist and back muscles, fix and brake the waist, and restore the normal alignment of the lumbar spine.

[0003] In the prior art, when patients are tractioned, they usually use their own gravity to pull the lumbar spine. Although this method can play a certain traction role, the effect is not good because the patient's own gravity is usually difficult to meet the torque required for lumbar traction. In addition, in this way, the patient's arms are easily fatigued, and it is difficult to maintain traction for a relatively long time. Summary of the invention

[0004] In view of this, an object of the present invention is to provide an orthopedic lumbar traction device to enhance the traction effect on the patient's lumbar spine.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0013] The beneficial effects of the present invention are:

[0014] In the present technical solution, the traction force required by the patient is cleverly changed by increasing the buoyancy. That is, when the patient stands inside the cylindrical shell, the patient himself will be subjected to buoyancy under the action of the internal liquid, thereby reducing the pressure on his lumbar spine.

[0024] like Figures 1 to 5As shown, the present invention is an orthopedic lumbar traction device, comprising a hollow cylindrical shell 1, one end of the cylindrical shell 1 is provided with a closed end plate 2, the other end of the cylindrical shell 1 is provided with a mounting ring 3 on the inner wall, the cylindrical shell 1 is symmetrically provided with a screw 7 inside, the two ends of the screw 7 are respectively rotatably connected to the closed end plate 2 and the mounting ring 3, and the end of the screw 7 connected to the mounting ring 3 extends to the top of the mounting ring 3, the cylindrical shell 1 is provided with a first mounting plate 5 on the outer side corresponding to the position of the screw 7, the first mounting plate 5 is provided with a rotating motor 8, the rotating motor 8 is fixed to the first mounting plate 5, and the output end of the rotating motor 8 is connected to the first mounting plate 5. A first bevel gear 10 is provided on it, and a second bevel gear 9 is provided on one end of the screw rod 7 located above the mounting ring 3. The first bevel gear 10 and the second bevel gear 9 are meshed. A bearing plate 11 is provided on the screw rod 7. Both ends of the bearing plate 11 are threadedly connected to the screw rod 7. A strap 12 is provided in the middle of the bearing plate 11. Connecting plates 13 are provided above both ends of the bearing plate 11. One end of the connecting plate 13 is slidably connected to the screw rod 7. A first annular ring 14 is provided in the middle of the two connecting plates 13. The side of the first annular ring 14 is fixed to the connecting plate 13. The interior of the cylindrical shell 1 is filled with a liquid that can make the first annular ring 14 float.

[0025] The working principle of the above technical solution is:

[0026] When the patient needs lumbar traction, first the patient's feet pass through the first annular ring 14, stand on the bearing plate 11, tie the strap 12 tightly to the patient's feet, and then control the rotary motor 8 to work, drive the second bevel gear 9 to rotate through the first bevel gear 10, and then drive the screw 7 to rotate, so that the bearing plate 11 slides downward on the screw 7 until it moves down to the patient's armpit and clamps on the first annular ring 14. That is, the patient stands inside the cylindrical shell 1 at this time. At this time, under the action of the internal liquid, the patient himself will be buoyant, which can reduce the pressure on his lumbar spine. At the same time, the buoyancy of the first annular ring 14 is transmitted upward through the patient's armpit, thereby achieving a lifting force on the patient's armpit, and then pulling the patient's lumbar spine. Of course, in the present specific embodiment, when the traction force of the buoyancy is insufficient, the support plate 11 can be continuously moved downward to move the patient's armpit downward, thereby partially pressing the first annular ring 14 into the liquid to increase the drainage volume, thereby increasing the buoyancy and thereby increasing the traction force on the patient's lumbar spine. When the traction is completed, it is only necessary to control the support plate 11 to move upward, and the patient can be lifted to the upper end of the cylindrical shell 1 and then walk out.

[0027] In one feasible manner, the first annular ring 14 is a hard ring (which can be understood as a hard swimming ring), and the liquid is water. The hard ring can enhance the support and position limiting capabilities for the patient and enhance the traction effect. The liquid is water, which is simple to obtain and easy to replace. Of course, it is not difficult to understand that a drain valve and a water inlet pipe should also be provided on the cylindrical shell 1. These are prior arts and will not be elaborated on herein.

[0028] In one practicable manner, a support ring 15 is provided on the lower surface of the first annular ring 14, and the support ring 15 is a hard ring. One end of the support ring 15 is fixed on the first annular ring 14, and a second annular ring 16 is provided on the outer surface of the support ring 15. The second annular ring 16 is a flexible ring (which can be understood as a flexible swimming ring), and the second annular ring 16 is fixed on the support ring 15. An air intake pipe 17 is provided on the second annular ring 16, and one end of the air intake pipe 17 is connected to the interior of the second annular ring 16, and the other end of the air intake pipe 17 extends to the top of the cylindrical shell 1, and a second mounting plate 4 is provided on the outer surface of the cylindrical shell 1, and an air pump 18 is provided on the second mounting plate 4, and the output end of the air pump 18 is connected to the air intake pipe 17, and the air pump 18 is provided with a remote control 19 for controlling the amount of gas injection, and the remote control 19 is electrically connected to the air pump 18.

[0029] The working principle of the above technical solution is:

[0030] After the carrier plate 11 moves to the designated position, that is, the patient stands on the carrier plate 11, the water in the cylindrical shell 1 is located below the patient's armpit, that is, the water level is relatively safe. When the traction force needs to be increased, the patient can control the remote control 19 to make the air pump 18 inject air into the second annular ring 16 through the air injection pipe to expand its volume, thereby increasing the drainage volume, increasing the buoyancy, and thus increasing the traction force. It should be noted that in this way, the patient's standing height in the water remains unchanged, and the second annular ring 16 collides, causing the water with an increased liquid level to be discharged by setting an overflow valve, etc., that is, the water level is always located under the patient's armpit, that is, it is always at a safe water level. Compared with the carrier plate 11 driving the patient to move downward to increase the drainage volume, this method is safer and more reliable. It is not difficult to understand that the components for controlling the intake and exhaust volume into the second annular ring 16 by the air pump 18 should also include control valves and control circuits, etc., which are prior art and will not be described in detail here.

[0031] At the same time, the provision of the support ring 15 can also prevent the second annular ring 16 from squeezing the patient's waist or chest when it expands.

[0032] In one feasible method, light rods 6 are symmetrically arranged on both sides of the screw rod 7, and the two ends of the light rod 6 are respectively fixedly connected to the mounting ring 3 and the closed end plate 2, and the connecting plate 13 and the supporting plate 11 are slidably connected to the light rod 6. The setting of the light rod 6 can greatly improve the sliding effect and stability of the supporting plate 11 and the connecting plate 13.

[0033] In one feasible manner, a heating component is provided on the outside of the cylindrical shell 1, and the heating component includes a heating wire 20. An installation cavity is provided in the wall thickness of the cylindrical shell 1, and the heating wire 20 is wound and arranged in the installation cavity. The heating wire 20 can heat the water to make the water at a temperature suitable for the patient, avoiding the problem of too low or too high water level causing discomfort to the patient. At the same time, warm water can promote the patient's blood circulation. When the patient feels uncomfortable during the attack period, he can soak in the water, which can reduce the load on the lumbar spine and also have a certain relief effect (similar to hot compress).

[0034] In one feasible manner, a sponge pad is provided on the outer surface of the first annular ring 14 to avoid hard contact with the patient's armpit and improve comfort, and a waterproof bag with an open end is provided on the inner side surface of the first annular ring 14 (not shown, it can be understood that the person is inside the waterproof bag and is not in direct contact with water), the open end of the waterproof bag is fixed to the inner side surface of the first annular ring 14, and the closed end of the waterproof bag is connected to the supporting plate 11. The provision of the waterproof bag can prevent the patient from direct contact with water, which may cause the skin to be immersed in water for a long time and cause discomfort.

[0035] In an practicable manner, the second annular ring 16 is an elastic airbag, and the elastic airbag has a good resetting effect when its inflated volume expands and deflates.

[0036] It is not difficult to understand that, in actual use, the cylindrical shell 1 can be buried under the ground, or stairs can be set up to facilitate the patient to enter the cylindrical shell 1.

[0037] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
