Description

  The present invention relates to a side brace position control device for a chair-type traction treatment device that performs traction treatment of the lumbar spine.

  Japanese Patent Application Laid-Open Publication No. 2003-259259 discloses a driving unit that automatically moves a side brace between a side support position and a retreat position (specifically, a second moving base, a side brace drive unit, a side arm, and a cam mechanism). A traction device provided with a part) is disclosed.

  However, the structure that automatically moves the side brace between the side support position and the retracted position of the prior art has the effect of automatically mounting the side brace, but it is always at the same position regardless of individual differences of patients. However, if the armpit is in contact with the patient's body when moving the armpit to the arm support position, manually position the patient or doctor or other therapist so that the armpit cannot be moved. There was an inconvenience that it was necessary to adjust and it was actually difficult to use. In addition, the side arm protrudes near the patient's head, so the transfer space is narrow, and the patient's head etc. comes into contact with the side arm during transfer, and the side arm interferes with the transfer operation and is difficult to transfer. Even after sitting, there was a problem that the patient had a feeling of pressure and could not be treated with relaxation. In addition, there is a drawback that the structure is complicated and expensive because the side arm is provided via the rotating shaft O and the rotating shaft P.

  In FIG. 1, 56 is a seat cover attached to the seat 5, 58 is a chair cover attached to the chair 2, and 27 in FIG. 2 is an elbow rest fixed to the traction frame 7.

  Next, the operation of the traction therapy device 1 according to the embodiment of the present invention will be described.

A therapist such as a doctor transfers the patient to the chair unit 2. At this time, the base 4 is elastically supported by the urging member 48 that constitutes the guide portion 47, and the side brace 8 is in a state where it can freely move within a suitable range at the transfer standby position. Further, the base 4 has a compact shape. Does not interfere with patient transfer.
After sitting on the chair 2, the patient places the side brace 8 near the flank (= between the trunk and both arms) and places the arm on the elbow rest 27. When the patient lowers the armpit 8 against the biasing member 48, the armpit 8 approaches the patient's flank. When the patient releases his / her hand from the side brace 8, the base 4 is pushed up by the urging member 48 and ascends, and the side brace 8 moves away from the patient's flank.

After sitting down, the waist orthosis 53 is worn. A waist brace 53 is wound around the lumbar region, and the distal ends are overlapped and coupled to hold the patient to the seat 5.
Next, after setting the set traction force value, the traction treatment time, the traction duration, the traction pause time, and the like on the operation panel unit 35, the traction treatment start switch (not shown) is operated to start the traction treatment.

  When the traction treatment is started, first, the reclining operation of the chair unit 2 is started. The traction treatment device contracts the rod portion 21 of the reclining actuator 19 to fall the entire chair portion 2 and simultaneously contracts the traction actuator 29 to move the seat portion 5 from the transfer position to the traction start position. When the chair part 2 reaches a predetermined lying position, the reclining operation is once stopped and the weight of the patient is measured by the load cell 31. Thereafter, the reclining operation is started again, and the reclining operation is ended when the chair portion 2 reaches a predetermined lying position.

  Next, the control unit 24 causes the rod portion 45 of the base actuator 43 to contract and moves the armpit device 8 provided on the base portion 4 upward so as to contact the both side portions of the patient. When the armpit device 8 lightly hits the armpit, the load cell 31 detects the pressing force, and the control unit 24 recognizes the output of the load cell 31 as completion of the setting of the armpit device 8 and stops the contraction of the base actuator 43.

  Further, the backrest portion 6 slidably provided on the traction frame 7 is in contact with the seat portion 5 by its own weight and the urging force of the return spring 51 before the reclining operation is started. When moving to the pulling start position, the patient can slide in the patient's head direction to prevent the patient's body from becoming cramped.

After the side brace 8 is brought into contact with both sides of the patient and the reclining operation is completed, the operation shifts to the traction operation.
First, the rod portion 33 of the traction actuator 29 is extended to move the seat portion 5 downward along the seat portion rail 15, and a traction force is applied to the patient's waist portion via the waist brace 53. The load cell 31 detects the thrust value of the traction actuator 29 as the traction force related to the traction therapy, and at the same time, the control unit 24 sequentially compares the thrust value of the traction actuator 29 detected by the load cell 31 and the set traction force value. Control related to the extension operation of the rod portion 33 during traction is performed so that the thrust value matches the set traction force value.

When the detected value of the load cell 31 indicates the set traction force value, the control unit 24 stops the extension operation of the rod unit 33.
After a while, the control unit 24 starts the contraction operation of the rod unit 33, and starts a traction pause operation (= relaxation operation).
In the traction treatment, the traction operation and the relaxation operation are repeated until the treatment time set by the timer means (not shown) elapses.

When the treatment time has elapsed and the timer means (not shown) indicates that the treatment time has been completed, the control unit 24 controls the contraction operation of the rod portion 33 and moves the seat portion 5 in a restoring manner to pull the operation. Exit.
Thereafter, the rod portion 45 of the base actuator 43 is extended to move the base 4 to the lower limit position, and the armpit device 8 is returned to the initial position. That is, when the armpit 8 is moved away from the armpit and moved to the vicinity of the flank, the base 4 comes into contact with the guide portion 47 and is urged by the urging member 48, and the armpit 8 is moved outwardly to the transfer standby position. To do.

  Next, the reclining actuator 19 is extended to raise the entire chair portion 2 and, at the same time, the traction actuator 29 is extended to move the seat portion 5 to the transfer position. When the chair portion 2 as a whole rises and the seat portion 5 moves to the transfer position, the reclining actuator 19 and the traction actuator 29 are stopped, the seat portion 5 is held at an optimum height for transfer, and the patient can easily transfer. It becomes possible to do. At this time, the backrest 6 is lowered by its own weight and the urging force of the return spring 51 and returns to the initial position. At this time, the damper 38 regulates the operating speed of the backrest part 6 so that the backrest part 6 does not fall suddenly.

In the first embodiment, the present invention is a chair-type traction therapy device, but the present invention can also be implemented in a bed-type traction therapy device.
Further, although not shown, as another example of the configuration related to the base shaft 34, a base rotation fixing mechanism may be additionally installed on the base shaft 34. Since the base 4 is pivotally supported on the base support frame 41 by the base shaft 34, if the traction force acts on the side brace 8 during the traction treatment, the component force of the traction force in the direction of tightening the patient's side (the rotation direction of the base 4). May cause pain in the armpit contact portion or feel cramped, and may not be able to perform traction treatment in a relaxed state. A base rotation fixing mechanism (an electromagnetic clutch or the like in the specific example) is provided on the base shaft 34 and is rotated by the base 4 during traction treatment (while applying intermittent traction force to one patient and performing treatment). By allowing the movement to be fixed, excessive tightening force does not act on the patient.
In the above other configuration examples, after the transfer, the patient positions the armpit device 8 at an optimal position with his / her will and sense, and after starting the traction treatment operation, the rotation of the base portion 4 is fixed. The force of tightening the side portions can be prevented from acting, and the pain in the side portions can be reduced and relaxed, so that traction treatment can be performed in a muscle relaxed state, and a higher therapeutic effect can be expected.

INDUSTRIAL APPLICABILITY The present invention can be applied to a side brace position control device for a traction therapy device that is easy to transfer, can cope with individual differences, and can perform traction therapy in a relaxed state.
The armor position control device 46 includes a guide part 47 that supports the base part 4 and guides and restricts the rotation of the base part 4. When the patient is transferred to the traction therapy device 1, The present invention can be applied to a side brace position control device for a traction therapy device that moves the device to the transfer standby position in the outward direction.
