Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low back pain treatment chair that is effective for people with low back pain who have difficulty in getting up from their seats due to injury or weakness in the lower back.

[Background Art] Many people suffer from low back pain, but low back pain occurs when a person stands on two legs against gravity and loses about 1 weight.
It is said to occur because a heavy head occupying / 10 is moved upside down with its spine and muscles supporting it. In general, the spine is curved in an S shape, and the spinal nerve passes through the center of the spine.The spine acts as a spring to reduce the load of gravity, and in addition, the cartilage called an intervertebral disc plays the role of cushion. Support. In this state, a command from the brain is transmitted to every corner of the body through the spinal nerve in the spine, and normal operation can be performed.

When the spine works in the same posture for a long time, fatigue gradually accumulates in the body, and when the muscle accumulates fatigue, blood circulation deteriorates and elasticity is reduced. Also, if an abnormality occurs in the lumbar spine, lumbar lordosis and kyphosis will occur, and the lumbar joint will be distorted, straining the disc supporting the vertebra, and distorting the posture as a result. Low back pain is when the body bends and presses on the internal organs, preventing normal movement.

[0004] There is no particularly effective method for treating this back pain, and there is no general method other than straightening the spine to improve blood circulation. As shown, the patient 51 is laid on a bed 52, the armpits are fixed to the bed 52 with a band 53, the band 54 is attached to the ankle, the weight W is attached, and the patient's posture is adjusted by applying an external force to the bent spine and the like. There is no effective treatment method or equipment other than correction.

[Problem to be Solved by the Invention] In the forced traction by the weight, the doctor determines the amount of the weight based on empirical rules, so that the traction is often not excessive, and in addition, the bed is used. For this reason, there is a problem that the required medical space is increased, and that the patient has to go to a hospital or the like having a treatment facility. In addition, it is difficult for patients with back pain to behave at home, and there are few cases where a helper is required to go to the hospital, and there has been a demand for the development of a back pain treatment device that can be easily treated at home. The present invention provides a low back pain treatment chair in which all of the above-mentioned problems are solved because the back pain patient uses his or her own weight at home to extend the spine straight.

[Means for Solving the Problems] A pair of armrests which can be adjusted up and down and opened and closed right and left, a waist rest attached to the armrests via a flexible joint, and a waist rest for a patient Using a tightening device using a ratchet mechanism to tighten and fix from both sides near the lower part of the rib and a low back pain treatment chair having an adjusting cylinder to adjust the height of the seat, lower the seat using a cylindrical cam by lever operation, This problem was solved by supporting the patient with a waist pad and floating in the air, and straightening the spine by its own weight. The waist pad is curved inward to conform to the patient's body shape, and includes a base made of a hard material and an inner material made of a soft material so that the patient can be supported without damaging the patient and the quadruped portion of the chair. The vehicle is provided with wheels so that it can move freely indoors and outdoors.

[Embodiment of the Invention] An embodiment of the present invention will be described based on an embodiment with reference to the drawings. FIG. 1 is a perspective view showing the structure of a low back pain treatment chair according to an embodiment of the present invention. FIG. 2 is a view showing a state in which a back pain patient is sitting on a back pain treatment chair according to the embodiment of the present invention and is being treated. FIG.
FIG. 4 is a view showing a movable state of a movable part of the back pain treatment chair according to the embodiment of the present invention.

FIG. 1 shows a whole view of a low back pain treatment chair 1 provided by the present invention, in which four legs are constituted by a thin iron pipe or a stainless steel pipe, and a rear leg 2 is provided with one leg.
A book pipe stands upright, and a front leg 3 is attached to this rear leg 2 in a bent state. The left and right legs and the front and rear legs are connected and fixed by a horizontal frame 4. Hind legs 2
Above the arm, there is an armrest 6 and an armrest reinforcing member 7 through a slide pipe 5. The armrest 6 can be slid up and down by about 180 mm to adjust the height in order to fit the physique of a patient with low back pain. Figure 3 shows the vertical slide situation.
This is shown in (C).

The armrest 6 is provided with a pair of waist supports 9 via a flexural joint 8 made of a rubber-like material. The waist pad 9 is fixed by sandwiching the flank around the lower part of the elbow bone of the back pain patient from left and right, and lowers the seat and hangs by the patient's own weight as described later, thereby treating the back pain. The inner surface of a base 10 made of a hard synthetic resin such as polycarbonate having a curved curve on the inner surface so as to conform to the physique of the patient, the inner surface made of a flexible material such as polyurethane which does not hurt the body. It has a member 11 so that the patient's waist can be fixed by sandwiching it from both sides.

The flexible joint 8 is not limited to vibration-proof rubber-like equipment, but may be any other equipment, such as a ball joint, as long as the waist rest 9 can tilt according to the patient's size. May be. FIG. 3B shows a situation in which the waist rest tilts.

The armrest 6 and the waist pad 9 have a ratchet mechanism (not shown) so that the patient's waist can be clamped and fixed from the left and right, as shown in FIG.
The ratchet is released by pulling the lock release lever 12 as shown in FIG. 4 and the left and right sides are opened at an angle of about 58 degrees, so that the tightening of the waist can be released. If the lock release lever 12 and the wire are provided below the armrest 6,
Since the hand operation is free during the treatment of the patient, light work can be performed.

The lower horizontally connected stay 4 has a gas-shock type adjusting cylinder 13 for adjusting the height of the seat 15, and when the lever 14 is pulled, the seat 15 moves up and down by about 60 mm so that the height suitable for the patient is adjusted. Can be adjusted. Using the cylindrical cam 17 between the seat 15 on which the patient sits and
There is a seat up / down lever 16 that can move up and down the seat by about 30 mm. After the patient is seated on the seat 15 and the flank is fixed with the waist pad 9, when the lever 16 is rotated, the seat 15 becomes
When the patient descends by about 0 to 30 mm, the patient is suspended by being supported by the waist pad 9, and an action of correcting the curvature of the spine occurs.

The chair 1 is not provided with a backrest for the purpose of correcting the curvature of the spine. In this embodiment, the chair 1 is described as being mounted on the floor. Or a structure such as a so-called wheelchair having a front wheel capable of turning to a large handrail wheel, and a structure in which the patient can freely move on the floor with his or her will.
