[Effect]

By tilting the upper body support part to an arbitrary angle, the upper body can be tilted in accordance with the condition of the blood donor so that the legs are higher than the head.

〔Example〕

Embodiments of the present invention will be described with reference to the accompanying drawings.

Example 1 The manual type will be explained with reference to FIG.

Reference numeral 1 is a cabinet-shaped fixing base, and reference numeral 2 is a bed main body separated into an upper body support part 3 and a lower body support part 4. The lower body support part 4 of this bed main body 2 consists of a waist support part 5 and a leg support part 6, and the waist support part 5 is connected to the fixed base 1.
The leg support section 6 is fixedly supported horizontally above the waist support section 5.
The fixing base 1 is attached via the inclined part 7 that is more inclined upward.
It is supported by the end plate 8 of the fixing base 1, which is raised substantially horizontally from above. Further, a pair of left and right bearing pieces 10, 10 is protruded near the end of the fixed base 1 through a gap between the end face 9 of the waist frame 5 and a small distance.
Near the lower end of the upper body support part 3 is rotatably attached to the upper body support part 3 by a support shaft 11 at 0 and 10. Further, a bearing piece 13 is protruded near the upper end of the end face 12 of the fixed base 1 near the bearing pieces 10, 10.
One end of the cylinder 16 of the gas spring 15 is rotatably attached to the cylinder 16. The cylinder 16 is filled with oil and high pressure gas, and is partitioned by a piston (not shown) having a small hole, and a piston rod 17 connected to the piston protrudes from one end of the cylinder 16.
A mounting piece 18 at the tip of 7 is rotatably attached to a bearing piece 19 protruding from the back surface of the upper body support part 3 by a support shaft 20, and an operating handle 32 is attached to this mounting piece 18. There is.

To explain the action of the gas spring 15, the piston rod 17 is normally maintained in its most extended state by gas pressure. When the piston rod 17 is pushed in, the piston compresses the gas, and the gas moves to the small hole of the piston or the opposite side.The piston stops at a position where the gas pressure is balanced, and the protrusion length of the piston rod 17 from the cylinder 16 increases. can be stopped at any position.

Next, the operation of the above embodiment will be explained.

The piston rod 17 of the gas spring 15 is at its maximum extension, and the upper body support portion 3 of the bed main body 2 is supported by the support shafts 11, 14, and 20 and is maintained at an angle of 50° from the horizontal position. .
Therefore, the blood donor on the bed main body 2 is held in a state where the upper body is about half raised. Next, when the operating handle 32 is grasped and the upper body support part 3 is rotated downward, the piston rod 17 is moved into the cylinder 1.
6 and can be stopped at any angle. When the piston rod 17 is at its shortest position, the upper body support section 3 is in a horizontal state on substantially the same plane as the waist support section 5, and does not descend any further. At this time, the blood donor is supported with his legs raised higher than his head and chest, allowing him to cope with anemia and the like.

In the first embodiment described above, the upper body support section 3 of the bed main body 2 is raised and lowered manually.

Example 2 The automatic type will be explained with reference to FIG.

The structures of the fixing base 1 and the lower body support part 4 of the bed main body 2 are the same as in the first embodiment.

Next, a pair of left and right bearing pieces 10, 1 are placed near the end of the fixed base 1 through the end surface 9 of the waist frame 5 and a small gap.
0 is provided protrudingly, and the upper body support part 3 is rotatably pivoted near the lower end by a support shaft 11 on this bearing piece.
A pair of support arms 2 are attached to the upper body support part 3 at a constant angle α with a small gap between them at the center of the upper body support part 1.
1 and 21 are fixed so as not to rotate. The lower ends of the support arms 21, 21 are rotatably attached to both sides of the tip of a piston rod 23 of a hydraulic cylinder 22, which is attached at one end to the center of the width direction of the back surface of the fixed base 1, using a support shaft 24. The piston rod 23 is biased by a spring 25 in the direction of being drawn into the hydraulic cylinder 22. The fixed base 1 also includes an oil tank 26 that communicates with the hydraulic cylinder 22 through an oil feed passage having a check valve in the middle, and an oil tank 26 that is provided in the middle of the oil feed passage and sends oil to the hydraulic cylinder 22. Electric pump 27 that advances piston rod 23 against spring 25
, an electric pump operation switch 28, a solenoid valve 29 that opens an oil return path to the oil tank 26 when the piston rod 23 retreats, and a solenoid valve operation switch 30. 29 is provided in a space 31 below the leg support 6 floating above the fixed base 1, and switches 28 and 30 are provided on the fixed base 1 on the upper body support 3 side.
The blood donor can press switches 28 and 30 on the end face 12 of the blood donor to change the angle as desired.

Next, the operation of the above embodiment will be explained.

When the power is turned on and the oil pump operation switch 28 is kept pressed, the oil in the oil tank 26 is sent to the hydraulic cylinder 22 and the piston rod 23 is advanced against the spring 25. Then, the lower body support part 3 in the substantially horizontal state gradually rises and when the switch 28 is released at an arbitrary angle, it stops at that angle. At the most advanced position of the piston rod 23, the upper body support part 3 stands up at an angle of 50 degrees from the horizontal position. In addition, solenoid valve operation switch 3
If you keep pressing 0, the solenoid valve 2 of the oil return passage
9 opens and the cylinder 22 is opened by the restoring force of the spring 25.
The oil is returned to the tank 26, the piston rod 23 is moved back, and the upper body support part 3 is gradually lowered, and when the switch 30 is released, it stops at that position. When the piston rod 23 is at the most retracted position, the upper body support part 3 forming an angle α with the support arm 21 is in a substantially horizontal state on the same plane as the waist support part 5.

Note that pneumatic pressure may be used instead of hydraulic pressure to move the piston rod 23 back and forth.

[Effect of idea]

According to the present invention, the bed main body is separated into a fixed base, an upper body support part, and a lower body support part, a lower body support door is fixed on the fixed base, and the upper body support part is pivoted so as to be tiltable at any angle. Therefore, the leg support part is raised higher than the waist support part of the lower body support part supported on the fixed base, and the lowest inverted position of the upper body support part is lower than the leg support part. Therefore, while the lower body of the blood donor is supported on the lower body support part on the fixed table, the upper body support part is tilted at an arbitrary angle, and the upper body of the blood donor is held in the blood collection position according to the blood collection condition. By changing the angle, it is possible to prevent the occurrence of anemia, etc. Furthermore, in the event of an emergency such as anemia, the upper body support section can be lowered lower than the leg support sections, making the head and chest lower than the legs, allowing for immediate and safe treatment without placing a burden on blood donors. .
