Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to beds for bedridden patients and the like.

[0002]

2. Description of the Related Art Conventionally, a bedridden patient cannot be laid sideways while lying on the bed. A nurse or an attendant moves the patient sideways and puts a futon on the back to maintain the sideways state, which requires a lot of labor.

Therefore, the inventor of the present invention devised a bed for bedridden patients (Japanese Patent Application No. 62-123068), which can be automatically laid sideways, and the blood vessels and nervous system which are almost parallel to the dorsal ribs. I found that massage stimulation (compression release stimulation) can be automatically performed and an unexpected recovery effect can be obtained, which is used for rehabilitation.

However, in the above-mentioned Japanese Utility Model Application No. 62-123068, when the left and right of the central boundary are alternately moved up and down, the futon of the stepped portion formed at the boundary is easily pulled in the left and right direction when forming the step to the right or left, and the relaxation is sufficient. Therefore, it was unsuitable for lateral tilting of relatively light patients.

[0005]

[Problems to be Solved by the Invention] In the present invention, when forming a right or left step at the central boundary, the futon on the step does not have to be pulled to the left or right and is sufficiently relaxed to move the patient to the right or left. The purpose is to hold it in a comfortable and lateral orientation.

[0006]

[Means for Solving the Problems] In order to achieve the above object, a plurality of parallel hoisting rods for reclining a patient are arranged in a front-back direction on a bed frame, and half of the parallel hoisting rods on both left and right sides of a central boundary portion are provided. At the same time and alternately to the left and right so as to be able to ascend and descend in opposite directions, and at the same time, on the left and right sides, every other parallel elevating rods that are adjacent to each other are elevatably supported, and on the left and right sides, the parallel elevating rods are adjacent to each other A bed of a bedridden patient or the like, which is rotatably supported by a round bar having a relatively large diameter, is formed between the two.

[0007]

In the present invention, the plurality of parallel elevating rods 2 and 3 are supported on the horizontal plane in the middle of the bed frame 1, and the futon 5 is laid on the plurality of round bars 4 on the center boundary portion c. Along the anterior-posterior direction of the spine along the back of the patient.

Half of the parallel elevating rods 2 and 3 on the left and right sides of the boundary portion c are raised on the left side and lowered on the right side in FIG. When every other parallel elevating rods 2 ', 2 ", 3', 3" which are adjacent to each other on the left and right sides of the section c are lowered as shown by an arrow a on the left side and raised as shown by an arrow b on the right side, the round bar 4 is It rolls as indicated by arrow e to move the futon 5 from the left and right sides toward the step. Therefore, the futon 5 concentrates and relaxes on the right step portion.

In FIG. 3, half of the left and right parallel elevating rods 2 and 3 are made lower on the left side and higher on the right side, and adjacent parallel elevating rods 2 ', 2 ",
Every other 3 ', 3 "is raised as indicated by arrow a'on the left side and lowered as indicated by arrow b'on the right side to roll the round bars 4, 4 as indicated by arrows e, e to the left. The futon 5 is concentrated and loosened on the facing step.

[0010]

EXAMPLE A plurality of parallel elevating rods 2 and 3 for reclining a patient are supported horizontally in the front-rear direction in the middle of a bed frame 1. As shown in FIG. 1, a forward / reverse gear 6 is provided on a horizontal forward / reverse drive shaft 7 at the bottom of the bed frame 1, and vertical racks 8 and 8 are meshed with the left and right sides of the gear 6.

The vertical racks 8 and 8 are integrally provided with alternating up-and-down upright rods 10 and 10 to the left and right through connecting rods 9 and 9.
The upright rods 10 and 10 have female screw housings 1 on the left and right sides, respectively.
1, 11 are provided, and female screws 12, 12 in the housings 11, 11 are provided.
Upright male screw rods 13 and 13 are screwed onto the
Forward / reverse drive motors 14 and 14 are connected to 2 and 12, respectively, to rotate the female screws 12 and 12 in the forward and reverse directions, whereby the upright male screw rods 13 and 13 can be moved up and down in opposite directions.

Horizontal horizontal rods 15 and 15 'are provided at the upper ends of the upright male screw rods 13 and 13, respectively, and the horizontal rods 15 and 15' are adjacent to each other and parallel to each other.
2 ", 3'and 3" are provided through the upright connecting rods 16 and 16 ', and the parallel elevating rods 2 and 3 are provided at the central boundary portion c as shown in FIG.
Can be supported on both left and right sides in the front-rear direction, and by rotating the forward and reverse gears 6 forward and backward, the parallel elevating rods 2, 3 for the left and right half can be simultaneously raised and lowered in opposite directions. .

Also, by rotating the female screws 12, 12 alternately or only in one direction, the adjacent parallel elevating rods 2 ', 2 "are indicated by arrows a, b and a', b'shown in FIGS. ,
3 ', 3 "can be raised and lowered. The raising and lowering rods 2', 2", 3 ', 3 "are rods having a circular cross section, and the round rod 4 is also a cotton rod having a circular cross section, or It may be made of leather or hardened rubber, and an upright plate 17 for preventing the round bar 4 from falling may be provided at the central boundary portion c.

[0014]

Since the present invention is configured as described above, not only can the bedridden patient or the rehabilitation patient automatically turn to the right or left, but also the futon 5 is concentrated and relaxed on the stepped portion for turning over. Therefore, the patient can lie sideways comfortably.

Claims (1)

[Scope of utility model registration request] 1. A plurality of parallel hoisting rods for reclining a patient are arranged in a front-rear direction on a bed frame, and half of the parallel hoisting rods on both left and right sides of a central boundary portion are supported so as to be able to hoist in opposite directions at the same time and right and left alternately. On the left and right sides, every other parallel elevating rods adjacent to each other are supported so as to be able to ascend and descend, and a round bar having a relatively large diameter is rolled between the parallel elevating rods on the left and right sides.
