Description

Waist cushion suitable for lumbar disc herniation

Technical Field

The utility model relates to the technical field of medical auxiliary instruments, in particular to a waist cushion suitable for lumbar intervertebral disc protrusion.

Background

Lumbar intervertebral disc protrusion is one of the more common lumbar diseases in clinic, patients often feel that lumbar pain and soreness are caused, and the lumbar pain and soreness radiate to one side or two sides of lower limbs along sciatic nerves, legs often have distending pain, numbness, coolness and even cramp, and the patients are difficult to walk and sit for a long time. Patients with severe symptoms can have intermittent claudication, lumbar lateral curvature, foot drop, muscular atrophy, weakened strength, even numbness of perineum, pricking pain, defecation, urination weakness and the like, so the treatment of the lumbar intervertebral disc protrusion is a long and long-term long-lasting process.

At present, the methods for treating lumbar disc herniation are many, and the methods mainly include surgical treatment, medicament treatment, acupuncture and massage, physical traction and the like. The operation treatment can change the original tissue structure of a human body, belongs to traumatic therapy, is painful for a patient, damages the tissue of the human body through the operation, causes the change of the tissue structure of the human body, is easy to increase the pathological changes of other tissues, has certain danger, is not easy to be accepted by the patient unless necessary. The treatment course of the drug is longer, the effect is slow and the treatment cost is high. Acupuncture and massage treatment is greatly influenced by human factors, the levels of a masseur and an acupuncturist play a crucial role in the recovery degree of patients, if the masseur and the acupuncturist select improperly, the pain of the patients cannot be relieved, the illness state of the patients can be delayed, and common patients mostly adopt intermittent treatment methods for acupuncture and massage treatment, cannot treat the patients continuously for a long time, and the curative effect is not ideal. Although physical traction can relieve symptoms to a certain extent, a patient needs to lie on a bed for a long time during treatment, the nucleus pulposus accommodated in the nucleus pulposus protrudes again under the pressure of the gravity of the upper body whenever the patient gets out of the bed or does not go home, so that the previous work is abandoned and the nucleus pulposus attacks repeatedly, and the traction appliance is generally large, is inconvenient to carry, generally needs to be in hospital and is used under the guidance of a doctor.

The problem that therapeutic apparatus exists to above-mentioned cushion or waist pad class, the utility model provides a section can be according to the lumbar pad that adapts to different crowds waist physiology crookedness to satisfy the outstanding patient's of lumbar intervertebral disc demand.

The technical solution of the present invention will be described clearly and completely through the following detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, a lumbar back cushion suitable for lumbar disc herniation comprises a base plate 1, a driving adjustment mechanism, a sliding mechanism and an elastic cushion plate 2. The sliding mechanism is covered on the base plate 1 in a sliding mode, one end of the elastic base plate 2 is fixedly connected with the sliding mechanism, and the other end of the elastic base plate is fixedly connected with any one end of the base plate 1. The driving adjusting mechanism is arranged at one end of the substrate 1 which is not fixedly connected with the elastic backing plate 2 and is in driving connection with the sliding mechanism. In general, the whole adjusting process can be understood as driving the adjusting mechanism to drive the sliding mechanism to move close to or away from the end of the base plate 1, which is fixed with the base plate 1, relative to the elastic backing plate 2 so as to adjust the curvature of the elastic backing plate 2.

The following is a detailed description of each mechanism:

the sliding mechanism comprises a sliding shaft 3, a sliding block 4 and a sliding groove 5. Any end part of the two side surfaces of the substrate 1 is provided with a sliding groove 5 along the length direction, wherein the length of the sliding groove 5 is greater than or equal to 1/2 of the length of the side surface of the substrate 1 and less than or equal to 2/3 of the length of the side surface of the substrate 1. The axle that slides 3 sets up on the top surface of base plate 1, and the both ends department of the axle that slides 3 is provided with sliding block 4, and sliding block 4 slides and inlays in sliding groove 5, and the restriction axle that slides 3 slides along sliding groove 5's the direction that sets up on the top surface of base plate 1 reciprocating.

The two side surfaces of the base plate 1 are provided with L-shaped fixed support plates 6 at one ends without the sliding grooves 5, and the tops of the L-shaped fixed support plates 6 are higher than the top surface of the base plate 1. A fixed shaft 7 is connected between the tops of the L-shaped fixed support plates 6. The elastic backing plate 2 is arranged on the top surface of the base plate 1, and two ends of the elastic backing plate are respectively fixedly connected with the sliding shaft 3 and the fixed shaft 7 through a plurality of fixing screws 8.

The driving adjusting mechanism comprises a driving motor 9, a screw rod 10, an adjusting groove 11, a nut block 12, a coupler 13, a motor fixing plate 14 and a screw rod fixing plate 15. The adjusting groove 11 is arranged at the center of the top surface of the substrate 1, the adjusting groove 11 is opened along the length direction of the substrate 1, and the length of the adjusting groove 11 is greater than or equal to 1/2 of the length of the top surface of the substrate 1 and less than or equal to 2/3 of the length of the top surface of the substrate 1. In certain cases, the length of the adjustment groove 11 may be slightly greater than the length of the sliding groove 5, and the both in combination may determine the maximum degree of bending of the elastic pad 2.

The screw 10 is disposed in the adjusting groove 11, and two ends of the screw 10 penetrate through the adjusting groove 11 and extend to two ends of the substrate 1.
