Function The bathing procedure and the function of this device when bathing a patient on the stretcher 25 using this device will be described.

In FIG. 1, the upper frame 6 of the transfer table 1 is swung to the left, and the stretcher 36 brought from the hospital room is attached to the side of the upper frame 6. When the upper frame 6 is swung to the left, the stretcher feeding device 13 protrudes from the upper frame 6 to the left, so if it is attached to the upper frame 6 next to the stretcher 36, the stretcher feeding device 13 will be placed behind the stretcher 25. You will be forced into it.

Next, the motor 20 of the stretcher feeding device 13 is driven to rotate the crosspiece cable body 15, and the projection piece 34 on the back of the stretcher 25 is rotated.
The stretcher 25 is pulled onto the transfer table 1 and brought to the center of the upper frame 6.

Next, the patient on the stretcher 25 is prewashed with hot water.

After pre-washing, the upper frame 6 of the transfer platform 1 is tilted to the right to approach the bathtub 29. At this time, in synchronization with the movement of the upper frame 6, the stretcher feeding device 13 advances from the upper frame 6 to above the bathtub 29 located to the right.

During this advance, the motor 20 is not energized, so the crosspiece cable 15 is in a free movement state with respect to the stretcher feeding device 13. Therefore, the stretcher feeding device 13 does not drag the stretcher 25 toward the bathtub 29.

Next, the motor 20 is driven to transport the stretcher feeding device 1.

is moved to the upper center of the bathtub 29. At this time stretcher 2
5, the rollers 32 arranged in a row transfer from the transfer platform rail 7 to the bathtub rail 33.

After the stretcher 25 is moved onto the bathtub 29, the upper frame 6 is moved to the left and returned to just above the lower frame 2.
At this time, the stretcher feeding device 13 moves back and forth in synchronization with the leftward movement of the upper frame 6 and is housed in the center of the upper frame 6.

When the patient arrives on the trestle 30 with the stretcher 25,
The bathtub 29 filled with hot water is raised by the operation of the elevating mechanism 28, and the person is immersed in the hot water to take a bath.

The operation of the stretcher feeding device 13 will be described.

When the motor 20 is not energized, the motor pulley 1
Since 9a and 19b can rotate freely, left and right pulleys 16a, 16b, 16c, 16d, and central pulley 21
a, 21b, 21c, 21d and motor pulley 1
The ropes 15 with crosspieces hung on 9a and 19b move freely.

When power is applied to the motor 20 and the motor 20 is rotated to the right or left, the motor pulleys 19a,
According to the rotation of 19b, the crosspiece cable body 15 moves to the left or right. The crosspiece rope body 15 has crosspieces 1 at predetermined intervals.
4 is attached, so when the stretcher feeding device 13 is connected below the stretcher 25 as described above, the crosspiece 14
is hooked on the protruding piece 34, and the stretcher 25 is moved to a desired position by rotation of the rope body 15 with crosspiece.

By the action of this stretcher feeding device 13, the stretcher 25 is taken from the stretcher 36 to the transfer table 1, or is pushed from the transfer table 1 to the stretcher 36, and similarly, the stretcher 25 is transferred from the transfer table 1 to the bathtub 29.
To push or take away something. This stretcher feeding device 13 is operated by operating switches 37a and 37b.

The synchronizing action of the stretcher feeding device 13 that moves on the upper frame 6 of the transfer table 1 in synchronization with the movement of the upper frame 6 will be explained.

In FIG. 1, the left arm 3a is connected to the lower left pivot portion 4.
9 to the left on a fan, the distance between the left frame pulley 23b of the upper frame 6 and the tip of the cable body 22 increases, and the distance between the base end of the cable body 22 and the right frame pulley 23a of the upper frame 6 increases. Since the distance between the upper frame 6 and the pulleys of the upper frame 6 becomes smaller, the bridge-attached cable body 15 stretched between both pulleys of the upper frame 6 moves to the left. The stretcher feeding device 13 moves to the left as it is pulled by the moving cables with crosspieces 15, and the stretcher feeding device 13 advances to the left from the upper frame 6.

Conversely, when the left arm 3a, which has been tilted to the left, is rotated to the right, the distance between the proximal end attachment part of the cable 22 and the right frame pulley 23a increases, and the distance between the left and right frame pulleys 23b and 23a increases. The cable body 22 located at the position moves to the right. Therefore, the stretcher feeding device 13 hooked to the rope body 22 moves to the right and advances from the upper frame 6 to the right.

Effects of the invention The present invention has a link-type transfer platform where the cables are crossed from the lower frame to the upper frame, and a stretcher feeding device is hooked to the cables, and the stretcher is moved in synchronization with the horizontal movement of the transfer platform. Since the feeding device moves forward and backward in the left and right lateral directions of the transfer table, when assisting with progressive bathing, if the transfer table is tilted to approach the bathtub or stretcher, it will synchronize with this tilting movement. The stretcher feeding device advances from the transfer platform. Therefore, the time and effort required to advance the stretcher feeding device can be saved, and the transfer operation can be carried out quickly.

Furthermore, since the stretcher transfer operation is performed by pulling or pushing the center of the back surface of the stretcher with a stretcher feeding device, the stretcher transfer can be carried out safely and the labor involved in transferring the stretcher can be reduced.

In addition, patients can enjoy bathing with peace of mind because the time required to transfer the stretcher is short and there is no risk of falling off the rails, and caregivers can assist with bathing with less mental effort. It became like this.
