[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved gatch bed for placing a patient in a shrimp posture during lumbar traction treatment.

[0002]

2. Description of the Related Art The prior art is disclosed in JP-B-51-30716, which discloses a main frame, a backrest mat on the main frame, a waist mat, and a leg supporting mat for supporting the lower limb. And a leg mounting table on which a leg supporting mat is mounted and which can be moved on a main frame.

[0003]

In the conventional Gatch bed, the leg supporting mat moves in the horizontal direction in the direction of the patient's foot along the main frame when the lumbar traction is performed, so that the traction suitable for enlarging the posterior side of the lumbar vertebra. There was a drawback that the angle could not be stabilized and the traction effect was small. Also, when a traction force is applied to the patient's waist, the leg supporting mat is pulled in the patient's foot direction, opening a gap between the waist mat and the leg supporting mat, and the buttocks of the patient fall between the both mats. There was a disadvantage.

Control circuit 2 for controlling the motor 14 to make an angle of
7, an angle circuit unit 28 for detecting and displaying the angle of the leg sheet 4 and a setting adjustment circuit unit 29 for setting or adjusting the angle of the leg sheet 4 are shown. The angle circuit unit 28 selects an angle display 30 for visually displaying the angle and a display value of the angle display 30 for displaying the trunk angle or for displaying the angle formed by the base 3 and the leg sheet 4. Display changeover switch 3
1 and the goniometer 25 for detecting the angle of the leg sheet.

The setting adjustment circuit section 29 is a setting switch for increasing the inclination angle of the leg sheet, and a setting 32 for comparing the actual measured value of the leg sheet 4 with the set angle and automatically shifting to the set angle. And a manual lowering switch 33 for automatically setting the inclination angle of the leg sheet 4 to zero at once.
And a stop switch 34 for urgently stopping the leg seat 4 moving toward the inclination angle of zero. The output of the setting device 35 controls the control circuit 27. The setting angle of the angle of the leg sheet 4 is set by the practitioner in accordance with the individual situation of the patient. When the angle of the leg sheet 4 is further changed after the movement is set, pressing the angle adjusting plus switch 37 moves the leg sheet 4 to increase the angle, and pressing the angle adjusting minus switch 38. And the angle of the leg sheet 4 is reduced.

In FIG. 1, reference numeral 40 denotes a controller in which electric components for tilting and moving the leg sheet 4 are stored, and various operation switches are disposed on the front of the controller. In FIG. 3, reference numeral 39 denotes a power switch, and in FIG.
Is a tape switch which conducts when a pressing force is applied to the upper surface. The switch 42 is a motor switch when a foreign object is sandwiched between the leg sheet 4 and the base 3 while the leg sheet 4 is moving to the inclination angle of zero. 14 is a safety member for stopping the operation.
In addition, the inclination angle of the back seat 5 is fixed to 30 degrees, but the base of the back seat frame 7 may be pivotally supported on the base 3 to change the inclination angle.

[Effects of the Invention] The present invention is based on the present invention. The present invention is based on the base 3, the back seat 5 extending obliquely upward from the upper part of the base 3 to one side, and the diagonal upward from the upper part of the base 3 to the other side. Since the front leg sheet 4 is provided with a seat moving mechanism 17 that moves the seat surface in the direction in which the seat 4 extends, the front leg sheet 4 is In this case, the angle of the leg sheet 4 can be suitably set to be constant in the direction in which the angle is increased, and the traction treatment can be performed with a smaller traction force than the conventional device. In addition, since the leg sheet 4 does not separate from the back sheet 5 and a gap does not open between the two seats 4 and 5, there is no inconvenience that the buttocks fall down between the two seats 4 and 5, which is comfortable. Lumbar traction can be performed.
In addition, as shown in FIGS. 1 and 2, when the buttocks sheet 6 is provided between the back sheet 5 and the leg sheets 4,
There is no gap between the seat 6 and the leg seat 4, and the buttocks do not fall between the seats 6, 4. Furthermore, since the buttocks do not fall between the back sheet 5 and the leg sheet 4, the weight of the patient is not applied to the chest orthosis 9 that stops the upper body on the back sheet 5 so that the upper body does not shift downward. Therefore, the patient does not suffer from the pain of the chest orthosis mounting part, that is, the chest, due to his / her own weight, and the traction treatment can be performed with confidence.

According to the present invention , an endless belt 21 that can rotate from the lower end of the leg sheet
, The sheet surface is movable without protruding from the predetermined frame, and the solid frame does not necessarily reciprocate, regardless of the position of the endless belt 21 at all. Can be towed without any problems. Therefore, the endless belt
There is no need to return the position of 21 to the original position, and there is no need to operate the leg sheet 4 at the start or end of treatment, which is convenient for operation. In addition, the solid frame does not reciprocate, but the endless belt moves within a frame of a fixed length, which saves space and allows a space between the traction machine 1 and the leg sheet 4 Therefore, the inclination angle of the leg sheet 4 was set to zero, and the patient could go up to various seats of the present invention from between the traction machine 1 and the leg sheet 4, which became convenient for use. .

The present invention provides a fixing / releasing machine in which the sheet moving mechanism 17 obtains an external signal to fix and release the movement of the sheet surface.
Since it is equipped with the structure 23 , the movement of the seat surface can be easily fixed and released by an external signal. It is possible to avoid an inconvenient situation such as being unable to do so or forgetting the fixing operation after being released, and the patient falling down when getting on and off and getting into danger. When the external signal is a signal extracted from the traction machine 1, the movement of the seat surface is fixed before and after the start of the traction treatment, and the movement of the seat surface is released during the traction after the start of the traction treatment. This operation is performed in conjunction with the operation of the towing machine 1, so that these operation steps are not required and the getting on and off of the patient is safe.
