Description

[Detailed description of the invention] This invention relates to an improvement of a traction device used for treating patients with lumbar disc disorders.

The patient with spinal disorders (hereinafter referred to as the patient) is placed in a supine position, the chest is fixed, and the lumbar region is pulled up using continuous traction or intermittent traction to widen the back of the spine and relieve pressure on the nerves exiting from the intervertebral foramen. So-called traction devices are known for placing the body in a removing position. The conventional traction device, as shown in Figs. 4 and 5,
Both require a long bed on which the patient lies, and in addition, a traction machine with a wire for pulling the orthosis must be placed side by side at the longitudinal end of the bed. For this reason, conventional traction devices are generally large and require a large installation space, making them difficult to install in hospitals with limited floor space, and even when they can be installed, they require a great deal of labor to install. In addition, since the structure requires a traction wire, the structure is complicated and requires a lot of effort to attach during treatment.

Therefore, the present invention was carried out with the aim of providing an improved traction device that can eliminate all of the above-mentioned difficulties.The traction treatment effect can be more fully achieved than before, and the installation footprint is small. It is extremely small, easy to handle during installation, and can be reliably attached to the patient during treatment with extremely simple operations.

That is, a seat part that can be moved back and forth with respect to the base and fixed thereon, and a backrest part that can change and adjust the inclination angle with respect to the base are formed into a chair shape. The rest is equipped with a traction armpit brace that can reciprocate in a direction parallel to the backrest.The seat and backrest move to change and maintain the patient in the required posture, and the reciprocating action of the traction armpit brace itself moves the patient to the desired position. It is characterized by being configured so that the parts are towed.

A specific embodiment of the structure of the present invention is shown in the accompanying drawings, FIGS. 1 and 2, and the details of the structure of the embodiment will be described below.

Reference numeral 1 designates a base of the orthosis, and a seat 2 installed on the upper surface of the base 1 and a backrest 3 erected from the rear side of the base 1 constitute a chair-shaped device.

The seat part 2 has a slide bar 4 installed on the back side,
By slidably inserting the slide bar 4 into a support 5 fixed to the base 1 side, the slide bar 4 is attached so as to be slidable in the front-rear direction a. The support body 5 is provided with a stopper 6, and is configured to be able to switch between a state in which sliding movement of the seat portion 2 is enabled and a state in which the sliding movement is prevented by operating the stopper 6. A thigh fixing belt 7 is installed on the upper part of the section 2.

Further, the lower end of the backrest 3 is rotatably attached to the base 1 by a horizontal pivot 8, and tilted backward at a predetermined angle from a vertical position (imaginary line) by a fixing release operation mechanism 9. It is configured so that it can be changed and fixed to any angular position between postures (solid lines).

An electric slide section 12 whose operation is controlled by an operation section 11 is mounted on the guide frame 10 provided on both sides of the backrest section 3 so as to be able to reciprocate in the direction shown by the arrow b. An electric slide portion 12 has a traction armpit brace 13 protruding from the portion 12.
It is composed of a traction drive section whose main components are a well-known motor and gears, and a weight detection section whose main components are a weight sensor. The operation unit 11 is composed of members such as a switch for turning on and off the power, a volume for setting the weight, a timer for setting the operating time, and a switch for selecting the traction mode.

Next, the operation of the traction device configured as described above when performing traction treatment will be explained.

Since the device is configured in a chair shape, it can be installed in a small space, and during installation, the base 1 is fixed so as to safely support a tilting patient.

The seat part 2 is fixed by the stopper 6, the backrest part 3 is fixed in a substantially vertical position, and the patient is seated on the traction device in a sitting position (imaginary line state). A thigh fixing belt 7 is fastened around the thigh, and a pulling armpit brace 13 of the electric slide section 12 is brought into contact with the lower part of the armpit.

Next, when the stopper 6 of the seat part 2 and the fixation release operation mechanism 9 of the backrest part 3 are released, the backrest part 3 tilts backward and the seat part 2 moves forward, changing the sitting posture. The patient is placed in a supine position, and during this operation, the position of the seat 2 and the inclination angle of the backrest 3 are selected and set appropriately, the seat 2 is fixed with the stopper 6, and the backrest is placed. If the part 3 is fixed by the fixing release operation mechanism 9,
The patient is maintained in a position compatible with traction therapy.

Once the treatment posture of the patient has been fixed in this way, the electric slide section 12 is then caused to perform a predetermined operation under the control of the operating section 11.

Then, the diagonally upward operation of the electric slide section 12 causes the traction armpit brace 13 to pull the patient's upper body diagonally upward, and as a result, the patient's lumbar vertebrae are attached to the thigh fixation belt 7. When combined with the fixation force and the downward gravitational force of the body's weight, the lumbar vertebrae become wider due to the traction force in the direction in which the upper body is tilted, which acts to relieve pressure on the nerves exiting from the intervertebral foramina. . The above-mentioned traction operation can be performed continuously for a certain period of time by setting the operating section 11, or can be performed repeatedly intermittently in a predetermined cycle.

Further, the traction force of the traction armpit brace 13 is appropriately set by the operation unit 11.

Furthermore, once the traction treatment is finished, the patient can be released into a free state by operating the seat 2, the backrest 3, the thigh fixing belt 7, and the traction armpit brace 13, contrary to the case of starting the traction treatment. .

Furthermore, as another embodiment, the electric slide part 12 may be housed in the base 1, and the electric slide part 12 and the traction armpit brace 13 may be connected by a rod or screw shaft.

In yet another embodiment, the traction armpit brace 13 may be fixed to the backrest 3 and the seat 2 may be electrically moved up and down to perform lumbar traction.

The advantage of the device of the present invention having the structure and operation described above is that the installation space is significantly smaller than that of the conventional bed-type traction device, and the traction device is compact and easy to handle.

In addition, since the traction arm brace itself, which is protruded from the backrest, is directly activated for traction, there is no need for a traction wire extending from a separate traction machine, and the device is simple and easy to attach the brace to the patient. Although it is extremely easy to operate and provides effective traction treatment overall, it is extremely advantageous in terms of running costs as it does not require a covering brace or wires. It was.
