Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a chair for rehabilitation exercise therapy capable of measuring rotational torque and vertical load,

The present invention relates to a chair for a rehabilitation exercise therapy for reducing pressure on a lumbar joint with a patient's own body weight, wherein the upper body and the lower body of the patient are adjusted in different directions to reduce pressure around the lumbar region, The present invention relates to a chair for rehabilitation exercise therapy in which a torque (a force in a rotational direction) and a pressure relieved at the lumbar vertebrae when depressurized are accurately measured to enable more precise, accurate and stable rehabilitation treatment.

The lumbar vertebra, also called the lumbar bone, is a part of the spine between the spine (thoracic spine) and the sacrum (sacrum), which is a bone structure that forms the waist. The lumbar supports the body through ligaments and muscles from the spine to the pelvic bone, maintains equilibrium, and also has the function of protecting the spinal cord and enabling movement of the spine.

As the plate of the vertebrae ages, the fibrous ring that surrounds the edge of the intervertebral disc develops centrifugal cracks and radiative ruptures. Especially when you try to lift a heavy object and move it to the side, The nucleus of the intervertebral disc is no longer piled up in the fibrous ring, and is caught between the radiative cracks and causes the disc herniation.

The most prominent symptom of lumbar disc herniation is lumbago, which is painful and painful with back pain, and the escaped discs stimulate the nerve root, resulting in a sensory abnormality in the legs in which the nerve root is distributed. In some cases, if the protruding nucleus is large and centrally located, it may have feces function, sexual dysfunction, and paraplegia.

In lumbar disc herniation, surgical treatment and rehabilitation are available, but after 3 to 4 weeks of stabilization after the lumbar spine, rehabilitation begins.

The conventional lumbar rehabilitation exercise apparatus is configured to perform rehabilitation exercise while the patient is lying on the bed horizontally, so that the decompression is generated in the lumbar vertebrae by the force pulling the body surface that strikes the bed. In this case, Since it is not caused by the weight of the patient, it is difficult to effectively achieve the therapeutic effect on the generation and maintenance of decompression, and the motion direction is shortened. Therefore, separate devices have to be used for movement in the other direction.

Particularly, in the conventional lumbar rehabilitation exercise treatment apparatus, the decompression is performed by moving the device in the lateral direction about the lumbar vertebrae while the patient is lying, so that the decompression can not be given vertically and the function of monitoring the applied depressurization And can not maintain the reduced pressure applied during exercise therapy.

To this end, the present inventors filed a domestic patent application No. 10-2013-0015548 entitled " Lumbar decompression apparatus using body weight and its control method ". Korean Patent Application No. 10-2013-0015548 discloses a chair type device having a cylindrical actuator. The patient's body weight is used to depressurize the lumbar joint. The patient's upper and lower bodies are adjusted in different directions, The pressure can be applied vertically, and the pressure applied to the load cell can be monitored using the load cell.

However, in the case of Korean Patent Application No. 10-2013-0015548, since the force measuring sensor is not in the power transmission process, the direction of the actual force and the measuring direction of the sensor may be inconsistent.

Above all, the present invention is intended to provide a more precise, accurate, and stable monitoring for treatment, in which the upper body and lower body of the patient are adjusted in different directions to reduce pressure around the lumbar spine. Particularly, it is desired that the power transmission is made through the load cell for measuring the rotational torque so that the accurate torque (the force in the rotational direction) with respect to the rotational direction and the pressure relieved by the lumbar vertebrae when depressurized are accurately controlled.

 In addition, in the case of the Korean Patent Application No. 10-2013-0015548, there is a disadvantage that a backlash phenomenon occurs due to a clearance generated between gears inside the electric cylinder.

The rotating part 140 is provided with an electric cylinder 150 mounted on the rotary part column 152 at one end on the rotary lower plate 147 and the end of the round rod 154 of the electric cylinder 150 is connected to one end of the gas spring 159 So as to form a connection portion 55. The other end of the gas spring 159 is fixed and mounted on the rotary column 152 at the other end on the lower rotary plate 147. The rotary part upper plate 143 and the rotary part lower plate 147 are provided with a first rotary shaft insertion hole 142 so that the rotary shaft 132 is inserted through the first rotary shaft insertion hole 142 of the rotary rotary lower plate 147, The upper end of the rotary shaft 132 is fixed after passing through the first rotary shaft insertion hole 142 of the rotary part upper plate 143.

One end of the rotary load cell bracket 184 is engaged with the round bar 154 and the gas spring 159 of the electric cylinder 150 by the bracket connecting rod 181 and the other end of the rotary load cell bracket 184 A rotary torque detecting load cell 187 is mounted between the rotating load cell brackets 184.

The rotating shaft 132 is provided with threads.

As the electric cylinder 150 is driven to cause the circular rod 154 to linearly move, the two rotary load cell brackets 184 are also moved so that the thread of the rotary shaft 132 rotates in the bracket hole 151 As the foot support 180 rotates, the hip support also rotates. As a result, the hip support is rotated at right angles to the left and right For example, 45 degrees to the left and 45 degrees to the right). Further, as the thread of the rotating shaft 132 rotates in the bracket hole 151, the rotational torque detecting load cell 187 located between the two rotating load cell brackets 184 is pressed, And the torque corresponding to the rotation is detected from the torque detecting load cell 187.

BACKGROUND ART [0002] In general, techniques for imparting a rotation function by using an electric cylinder are in a form of directly coupling an electric cylinder and a rotating structure. However, in the present invention, the linear force of the electric cylinder is not directly coupled to the foot support 180, which is the rotating body, but is transmitted through the rotating load cell bracket 184, The detection load cell 187 is used to detect the change of the minute force in the rotation direction.

FIG. 7 is a view for explaining the movement of the rotating load cell bracket according to driving of the electric cylinder in the rotating part of FIG. 6, and FIG. 8 is a view for explaining the movement of the footrest supporting part according to driving of the electric cylinder in the rotating part of FIG.

7 (a) and 8 (a) show a state in which the electric cylinder 150 is in a stopped state, and FIGS. 7 (b) and 8 (b) show a state in which the electric cylinder 150 is driven, The pedestal support portion 184 and the pedestal support portion 180 are rotated.

When the round bar 154 of the electric cylinder 150 performs a linear movement, that is, when the round bar 154 of the electric cylinder 150 is extended, the gas spring 159 is contracted, The rotary load cell bracket 184 rotates to the right and the rotary shaft 132 in the bracket hole 151 rotates and the foot support 180 rotates to the right as well.

That is, when the electric cylinder 150 pushes the circular rod 154 (that is, stretches), the length of the electric cylinder expands. This process is performed by rotating the lower body to the left side with the upper body fixed . In the opposite case, when the electric cylinder pulls the round bar, the lower body is driven to rotate to the right.

The rotational driving part using the electric cylinder is accompanied by a backlash phenomenon due to a clearance occurring between the gears in the electric cylinder. This phenomenon causes the measurement value to become unstable or the rattling feeling of rattling is transmitted to the patient There are side effects. In order to solve this problem, the present invention solves the backlash phenomenon by mounting the gas spring 159 in the direction of canceling the pushing force of the electric cylinder.

Since the electric cylinder is usually different in pushing force and pulling force, the gas spring is mounted in such a direction as to cancel the stronger directional force of the electric cylinder, and in the case of the present invention, the force in the pushing direction of the electric cylinder is stronger As shown in Fig. 5, so as to be positioned below the round bar 154 of the electric cylinder 150. [

9 is a diagram for explaining a comparison between a general torque measurement method and a torque measurement method of the present invention.

9 (a) is a conventional method for measuring rotational force, and the rotational force is measured by mounting the sensor at the end of the rotating body. FIG. 9 (b) is a rotational force measuring method of the present invention, in which the load cell is mounted on the middle of the foot support 180 as a rotating body, and the force actually applied is measured. In other words, in the conventional method, the sensor for measuring the force is not in the power transmission process, while the present invention is the most significant difference in that the power transmission is performed through the load cell 10 for measuring the torque. The difference between these methods is that the same force can always be measured regardless of the rotation angle, considering that the direction of the rotation torque is the tangential direction of the locus circle centered on the rotation axis. In the conventional technology, there is necessarily a case where the direction of the actual force is inconsistent with the measurement direction of the sensor. In this case, the measurement error generated in this case is solved by software algorithms and the like, which is troublesome and inaccurate.

Using the structural characteristics of the present invention, which are capable of rotating torque measurement, the machine may move the patient, or the patient may move the machine. The former case can be divided into passive treatment, the latter can be divided into active motion, and both the passive and active can be made through the structure described in the present invention. Isotonic, isokinetic, and isometric movements are possible in patients with lumbar motion, and the ability to measure the range of motion and muscle strength at each rotational angle is also an advantage.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, Modification is possible. Accordingly, the spirit of the present invention should be understood only in accordance with the following claims, and all equivalents or equivalent variations thereof are included in the scope of the present invention.
