Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a bathing device for bathing a bedridden patient (hereinafter referred to as a patient).

Conventional technology Conventionally, as disclosed in Japanese Patent Publication No. 44-27800, rollers were provided on the back of the stretcher as a mechanism for moving the stretcher to the upper part of the bathtub, and the stretcher on which the stretcher was placed and moved was equipped with rollers. There was one in which parallel rails were provided on the upper part of the bathtub, and parallel rails were also provided on the upper part of the bathtub at the same intervals as the rails. In this system, the stretcher placed on the rails is transferred from the stretcher rails to the bathtub rails via rollers.

Problems that the invention aims to solve With the conventional mechanism for transferring a stretcher, which consists of rails and rollers, it takes a lot of effort to transfer the stretcher due to the rotational resistance of the rollers, and it takes a considerable amount of time to transfer the stretcher. Since force is applied to move the stretcher in horizontal and lateral directions, the forces applied to the front and rear of the stretcher tend to become unbalanced. The disadvantage was that it was difficult to move and required a lot of effort.

Furthermore, vibrations were generated when the rollers made contact with the rails, causing discomfort to patients.

Means for Solving the Problems The present invention solves the shortcomings of the prior art, allows the caregiver to transfer the stretcher with slight force, allows the patient to transfer comfortably, and provides bathing assistance and bathing without discomfort for both the caregiver and the patient. The purpose is to provide a labor-saving bathing device that allows for

Function The procedure for bathing a sick person using the present invention is to place the sick person on the stretcher 2 on the stretcher 30, place the stretcher 30 adjacent to the elevating bathtub 1, insert the connection fitting 39 into the connection receptacle 21 to establish communication, and then turn the caster. The fixing mechanism 48 is operated to simultaneously fix the rotation of the wheels and the rotation of the mounting axis of the four casters 31.

Next, the valve knob 51 is operated to open the manual valve 22, and the hot water present in the air pipe 16 that has entered through the spout 5 and the like is drained.

Next, power is applied to the blower 14, and the stretcher 2 is pushed toward the elevating bathtub 1. After the stretcher 2 is transferred from the stretcher guide mechanism 36 onto the guide mechanism 3, the blower 14 is turned off, the bathtub 9 is raised, and the patient is immersed in the bath water.

When leaving the bath, lower the bathtub 9 and then turn the valve knob 5.
1 to open the valve 22 to drain hot water in the air pipe 16, operate the blower 14, and transfer the stretcher 2 toward the stretcher 30. When the transfer of the stretcher 2 is completed, the application of electricity to the blower 14 is stopped, the connection plug 39 is removed from the connection receiver 21, the caster fixing mechanism 48 is released, the stretcher 30 is placed in a free running state, and the patient on the stretcher 30 is moved. Move it to the desired location.

To explain in more detail the transfer state of the stretcher 2 in the above-mentioned flow, when the stretcher 2 is transferred from the stretcher guide mechanism 36 to the guide mechanism 3,
The blower 14 is driven and compressed air produced by the blower 14 is applied to the stretcher guide mechanism 36 and the guide mechanism 3. One of the compressed air of the blower 14 is connected to an air pipe 16, a branch throttle valve 20, a connection fitting 21,
The stretcher guide mechanism 36 is connected to the stretcher guide mechanism 36 via the connection fitting 39 and the stretcher pipe frame 37 in this order.
leading to.

The compressed air introduced into the stretcher guide mechanism 36 is blown out from the outlet 35 in the flat upper surface of the stretcher rigid hollow body 34 of the stretcher guide mechanism 36 . The ejected compressed air causes the sliding rail 46 existing on the stretcher rigid hollow body 34 to float, and the sliding rail 46 created by the gravity of the stretcher 2
and the stretcher rigid hollow body 34 is reduced. Therefore, when the stretcher 2 is moved on the stretcher guide mechanism 36 while blowing out compressed air from the discharge port 35, the sliding rail 46 is pushed by the caregiver and moves on the stretcher guide mechanism 36 with little frictional resistance. do.

The sliding rail 46 is the stretcher guide mechanism 36
The stretcher guide mechanism 36 is moved upward and transferred to the guide mechanism 3 located on the longitudinal extension line of the stretcher guide mechanism 36. Another compressed air produced by the blower 14 is connected to the guide mechanism 3 through an air pipe 16, a throttle valve 18,
It is attached via the pipe frame 13,
Compressed air is ejected from an ejection port 5 on the flat upper surface of the rigid hollow body 4.

When the sliding rail 46 is transferred onto the guide mechanism 3, the back surface of the sliding rail 46 is pushed up by the ejected air, so the frictional resistance between the sliding rail 46 and the rigid hollow body 4 is extremely small. The slide 46 is slid onto the guide mechanism 3, and when the stretcher 2 is moved to an appropriate position on the guide mechanism 3, the blower 14 is stopped.

To transfer the stretcher 2 from the guide mechanism 3 to the stretcher guide mechanism 36, compressed air is applied to the guide mechanism 3 and the stretcher guide mechanism 36, and the stretcher 2 is transferred from the guide mechanism 3 to the stretcher guide mechanism 36. push away

The stretcher 2 is inserted into the hole 24 provided in the rectangular flat plate 23.
When the pin 47 is located directly above the hole 24, the pin 47 is automatically biased by the appropriate spring.
gets stuck. This fitting structure is provided to temporarily fix the stretcher 2 at an appropriate position above the bathtub 9, and the pin 47 is connected to a remote control release mechanism (not shown) using an appropriate cam, rod, etc.
By moving the stretcher 2 into the interior of the stretcher 2, the temporary fixation of the stretcher 2 to the bathtub 9 can be released.

In addition, in the case of the second embodiment when draining hot water in the air pipe 16, when the blower switch 26 is turned on, a timer 50 is activated, and the solenoid valve 49 is opened for a predetermined time set by the timer 50, and this predetermined time elapses. Then, the solenoid valve 49 closes and the blower 14 rotates. While the electromagnetic valve 49 is open, hot water that has entered the air pipe 16 from the spout 5 is discharged.

Furthermore, in the case of the third embodiment, when the bathtub 9 is lowered, the hot water that has entered the rigid hollow body 4 is released into the float valve 5.
2 is floated, and the hot water in the rigid hollow body 4 is drained downward through the housing 53 and the water outlet 54.
When the hot water in the housing 53 is drained, the float valve 52 closes the water drain port 54. Therefore, with this configuration, when hot water and water in the rigid hollow body 4 are drained and compressed air is applied to the rigid hollow body 4, the water drain port 54 acts as if it were closed.

Effects of the invention The present invention has a configuration in which a jet port is opened in the flat upper surface of a rigid hollow body of a guide mechanism on which a stretcher, etc. is placed, and compressed air is jetted out from the rigid hollow body. Since the valve is installed in communication with the valve, the hot water that exists in the air passage is drained from the valve, so during normal use, the hot water splashes from the spout and splashes on the patient and the caregiver, causing discomfort to both. I have never heard of giving someone.

In addition, the sliding rail of the stretcher sliding on the rigid hollow body receives upward pressure from the compressed air ejected from the jet nozzle, so the frictional resistance generated by the sliding sliding rail against the rigid hollow body is extremely small, and the stretcher slides smoothly. The rail can be moved on the guide mechanism with a slight external force. Therefore, the labor of the caregiver to transfer the stretcher supported by the sliding rail from the stretcher to the top of the bathtub and the labor of the caregiver to transfer the stretcher from the top of the bathtub to the stretcher are greatly reduced, and the labor required for transferring the stretcher from the top of the bathtub to the stretcher is greatly reduced. The labor required for assistance at the time was saved.

In addition, since the sliding rail supporting the stretcher moves while being pressed upward by the ejected air, the vibrations of the stretcher when moving on the guide mechanism and when transferring from the stretcher guide mechanism to the guide mechanism have pressure. It is absorbed by the air layer and becomes extremely small, greatly reducing the discomfort caused by vibrations to the patient on the stretcher.
