[0002]

2. Description of the Related Art As a conventional technique, there is a technique disclosed in Japanese Patent Application Laid-Open No. Hei 3-16563. This technology comprises a bed frame and a side arm, the side arm having two shafts provided on the bed frame, a first arm mounted on the shaft, and a second arm rotatably mounted on the first arm. Two arms,
And a distance between the two shafts is smaller than a distance between both sides of a person.

[0003]

When a patient suffers from lumbar traction therapy, the patient becomes physically and mentally tense and stiffens the muscles surrounding the lumbar spine. If the muscles surrounding the lumbar spine are stiff, the traction applied to the lumbar brace will act more on that muscle, and the traction that acts on the lumbar spine itself will be reduced, making it impossible to pull the lumbar spine accurately and reliably . Therefore, it is important to relax the patient during traction treatment without causing any pain.

[0004] The armrests are towed healers (hereinafter referred to as patients).
Are tightened in correlation with the magnitude of the traction force applied to the waist, but in the conventional device, when the armpit is applied to the side of the patient, the longitudinal direction of the bed in plan view There is a problem that the tightening force changes according to a change in the angle between the armature and the arm for arm extending from the shaft, and the tightening force is not constant with respect to the traction force. That is, the tightening force is affected by the difference in the chest width of the patient, and the narrower the chest width, the smaller the tightening force of the armpit, and the wider the chest width, the greater the tightening force of the armpit, and the tightening force is constant. It was inconvenient.

The present invention solves the above-mentioned problems, and the force for tightening the side of the patient is not affected by the difference in the physical size of the patient.
An object of the present invention is to provide a bed with a sliding arm that can perform traction treatment while always providing a suitable tightening force to a patient. That is, the present invention provides a bed (1) on which a supine human body is placed, and a short side (2a) of the bed (1).
And a pair of sliding side arms extending in the longitudinal direction of a bed (1) having a base end slidably attached to the slide shaft (7). (8) and the slide shaft (7).
Is attached to the side of the frame (2) where the head of the human body is located
In addition, the slide shaft (7) is connected to the bed (1).
Toward the center of the patient's foot rest (1b)
When the tension is applied to the sliding arm (8) in the direction of the patient foot rest (1b) of the bed (1), the base of the arm (8) is attached. Slides provided on
A moving arm (9) is a bed with a sliding arm, wherein the moving body (9) slides to a central portion in a lateral direction of the bed (1).

[0006]

According to the present invention, a sliding arm 8 is provided on the frame 2 of the bed 1 for towing, and is used for lumbar traction treatment. That is, the traction machine 18 is installed at one end of the bed 1, the patient is laid on the bed 1, the tip of the sliding arm 8 is applied to both sides of the patient, and the waist brace 17 is attached to the patient's waist. Then, the lumbar brace 17 is towed by the traction machine 18 via the wire 19, and an appropriate traction force is applied to the waist of the patient.

When the above-mentioned tension is applied to the sliding arm 8 in the direction of the patient's foot rest 1b of the bed 1, the sliding arm 8 slides on the slide shaft 7 to move the bed 1 To the center in the direction. Sliding arm 8
Is rotatable and fixed about a sliding portion 9 along a vertical plane.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
Comprises a frame 2 formed of a rectangular frame, legs 3 (FIG. 2) for supporting the frame 2, a lower body mounting table 4 and an upper body mounting table 5 slidably mounted on the frame 2, and an upper body mounting table. A pillow portion 6 (FIG. 2) on which the patient's head rests is formed at the tip of the patient head 5 in the direction of the patient head placement portion 1a.

A slide shaft 7 is attached to the short side 2a of the frame 2. The slide shaft 7 slides freely on the shaft 7, and a fool is on his / her side with both sides of the fool being sandwiched. A sliding arm 8 is provided which prevents movement in the direction. The slide shaft 7 is made of a rod-shaped shaft member having a circular cross section that is bent in a U-shape in plan view. The sliding arm 8 is a member that is slidably attached to the slide shaft 7, and is a sliding member that is externally fitted to the slide shaft 7 and uses a slide bearing or a fluororesin cylinder or the like as a sliding surface. A moving part 9, an extending arm 10 extending from the sliding part 9 toward the patient mounting part 1 b of the bed 1 above the upper surface of the bed 1 on a horizontal plane, and And an armrest 10 formed by bending the tip of the arm 10 in the vertical direction and mounting an appropriate cushioning member.

The sliding portion 9 is rotatable along a vertical plane orthogonal to the horizontally extending slide shaft 7,
The side abutment 11 can be freely rotated upward. When the side abutment 11 is hung down and rotated toward the bed 1, a number of movements are required between the bed 1 and the lower end of the side abutment 11. An appropriate locking mechanism (not shown) is configured between the slide shaft 7 and the rotating portion so as to rotate and stop at a position having a slight gap of centimeters.

The slide shaft shown in the second embodiment of FIGS. 3 and 4 is a square slide shaft 12 having a rectangular cross section.
The shaft 12 is supported and screwed on the short side 2 a using the support side 20, and the sliding part is a square sliding part in which a plurality of roller bearings 14 are mounted inside a square frame member 13. The roller bearing 14 is fitted on the surface of the rectangular slide shaft 12 in a state where the roller bearing 14 is in contact with the surface. In the case of the second embodiment, since the rectangular sliding portion 15 cannot rotate on a plane perpendicular to the axial direction of the rectangular slide shaft 12, the rotating portion 16 is moved between the rectangular sliding portion 15 and the extension arm 10. And the extension arm 10 can be rotated in the vertical direction.

In the traction treatment, the caregiver once lifts the armrest 11 and then hangs down while applying to both sides of the patient lying on the bed 1. The waist brace 17 attached to the patient,
When the wire 19 of the traction machine 18 is pulled in the direction of the patient's foot, the patient gradually moves in the direction of his / her own foot, and the armpits 11 hit the both sides of the patient, and the patient places the armpit 11 on the patient's foot. The pressing force is applied in the direction of the placing portion 1b, and the movement in the foot direction is prevented by the side contact portion 11.

When a pressing force is applied to the armrest 11 in the direction of the patient foot rest 1b of the bed 1, the sliding part 9 integrated with the armrest 11 is also pulled in the direction of the patient foot rest 1b. . The slide shaft 7 moves toward the center of the bed 1 in the lateral direction,
Since the bed 1 is depressed and bent in the direction of the patient foot rest 1b, the sliding portion 9 slides on the slide shaft 7 toward the center in the short direction. Along with the sliding of the sliding portion 9, the extension arm 10 and the side abutment 11 also slide to the central portion in the lateral direction of the bed 1, and the patient sandwiched between the left and right side abutments 11 holds both sides thereof. It is pressed by the armpit 11. As a result, the armpit 11 presses both sides of the patient in proportion to the traction force applied to the treatment. As described above, during traction treatment, the armpits 11 press both sides with an appropriate force, so the patient applies force to the upper limbs to tighten the armpits to prevent the armpits 11 from coming off. Such an operation is almost unnecessary.

[0014]

According to the first aspect of the present invention, the tightening force of the sliding arm 8 is not affected by the chest width of the patient, and is suitable for both narrow and wide patients. The clamping force of the sliding arm 8 works in the same way, and the clamping force is not too strong or too weak, and does not give the patient unnecessary tension or discomfort, which is advantageous.

According to the first aspect of the present invention, the slide shaft 7 is depressed in the shape of an ellipse on the side of the patient's foot rest 1b. It becomes a coefficient that is converted into the side part tightening force, and the side part tightening force depends on this angle. Therefore, if the bending angle is appropriately set, the tightening force of the armpits of the patient by the armrests 11 can be suitably set, and there is an effect that setting and changing adjustment are easy.
