Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for bathing patients, such as physically disabled people and bedridden elderly people, on stretchers, and is particularly suitable for bathing a large number of patients in hot water continuously in hospitals, nursing facilities, etc., and for treating patients individually. The present invention relates to a hot water bath device that can be used for bathing in hot water.

Traditionally, hospitals and nursing care facilities have continuously bathed a large number of patients with the assistance of several nurses on a set day of the week, but patients with cerebral palsy and infants have been treated with hot water baths along with the large number of patients mentioned above. It is not suitable for bathing all at once, and the current situation is that each patient is given a separate bath in a single bathtub whose bottom height can be adjusted in a separate bathroom.

A continuous hot water bath device is disclosed in Japanese Patent Publication No. 41595/1983. This device has a moving table with roller parts installed on both sides of a bathtub equipped with an elevating roller part, and a washing stand and a wiping table with roller parts are arranged on both sides of both moving stands. The patient is sequentially bathed in hot water while moving the stretcher.
However, when attempting to use the bathtub in this device alone, the moving table and washing table must be moved from their designated positions to a narrow space in the bathroom, and while avoiding them, the transport vehicle for the patient bathing alone must be moved. I had to carry it up to the side wall of the bathtub.

Furthermore, JP-A-52-113595, JP-A-51-
No. 42390 and Japanese Unexamined Patent Publication No. 51-2284 propose a structure in which a cleaning tank or a carrier with a cleaning tank is connected to a single bathtub in contact with each other. However, in these systems, a nurse is placed between the bathtub and the washing vehicle to assist the patient so that the patient's head does not submerge in the hot water, and to set intervals between showering and wiping the patient. I don't have it. In addition, if a washing tank that is in contact with the bathtub or a patient on a transport vehicle is washed, splashes of washed waste water will contaminate the bath water, so the purpose of separating the bathtub and washing tank together is not achieved, and the continuous hot water bath system It is not suitable as such.

Based on the technical state of the conventional hot water bath equipment mentioned above, in order to use the continuous hot water bath equipment as a stand-alone bathtub for patients, it is necessary to provide a connecting rail that can be folded and stored between the bathtub and the transport vehicle having a cleaning means. There is. When the connecting rail is stored, the patient can be easily and reliably bathed without the risk of injury to the patient's body during the nursing care operation.Moreover, when the connecting rail is assembled and arranged horizontally, It is possible to easily connect a cleaning transport vehicle to the patient, and it is also possible to set intervals between nurses' assistance.

In the present invention, when the connecting rail pivoted to the side wall of the bathtub is placed horizontally, it is firmly placed above the upper edge of the side wall, so the stretcher can freely slide into and out of the bathtub, and when folded downward, it is stored in the side wall. Therefore, a continuous hot water bath system can be used for a single bathtub. An embodiment of the present invention will be described below with reference to the accompanying drawings.

The gap h is closed except when the locking rod 20 is inserted through the locking rod 9 and the stretcher 5 is lifted and opened when the stretcher 5 passes. The manual lever for raising the locking rod 20 may have a different structure depending on the installation location of the rail frame.

The lifting frame 3 with the lifting rail frame 2 fixed to its upper surface has chains 22 connected to its four corners.
is connected to a known drive unit (not shown) provided in a housing 23 that is integrated with both end walls of the bathtub. This is then moved up and down by a lift switch 25 provided on the operation panel of the housing 23. As shown in FIG. 2, the elevating rail frame 2 moves up and down between a raised position where it engages with the connecting rail frame 6 and a position where it is immersed in the lower part of the bathtub water. As shown in FIG. 3, the connecting rail frame 6 is pivotally attached to a pair of mounting members 26 provided on the upper outer surface of both side walls 4 of the bathtub via an inverted L-shaped connecting member 27. Both ends of a U-shaped portion 32 of a support frame 31 are pivotally attached to the center portions of the inner surfaces of both side frame plates of the rail frame 6 via a support shaft 30. The tips of a pair of rods 33 integrally formed from the center of the support frame 31 are pivotally connected to a support shaft 35 screwed into a threaded rod 34. A nut portion 36 is provided at the center of the support shaft 35, and when the threaded rod 34 rotates, the support shaft 35 moves up and down by the nut portion 36.

The upper end of the screw rod 34 is a bearing 38 on the side wall 4.
The lower side thereof has a worm wheel (not shown) and is supported by a receiving plate 39. Worm that meshes with the worm wheel (not shown)
The shaft rod 40 extends into the housing 23, and is connected to a sprocket 41 provided at the end thereof by a chain 43 to a gear provided on the output shaft of a motor 42. motor 42
Forward/reverse rotation control is operated by switch 24. A roller 45 is inserted on both sides of the nut portion of the support shaft 35 that is screwed into the threaded rod 34, and the roller 45 slides in contact with the surface of a reinforcing plate 46 fixed to the side wall 4.
The spiral rods are designed to withstand the load of a stretcher with the patient supine.

The transport vehicle 8 connected to the rail frame 6 has leg wheels 48 at the four corners.
A hydraulic cylinder 50 as a support is erected in the center of a horizontal H-shaped leg frame 49 equipped with a pedal 51.
The upper end of the operating rod 52 is driven by a support plate 5.
The rail frame 10 is installed horizontally via 3. On the other hand, at the upper end of the cylinder 50, a washed sewage receiving tank 53 having an opening slightly wider than the stretcher is fixed at its center. Both ends of both frame plates 12 of the rail frame 10 are provided with protruding locking pieces 55 for preventing the stretcher from traveling. A locking rod 56 is provided at both ends of the other side, and the locking rod 56 opens the gap h only while the handle 59 is pulled toward the front, allowing the stretcher to run on the sliding plate. Furthermore, a pair of connecting protrusions 57 are provided on the front surface of the rail frame 6, and when these are inserted into the opening 8 provided in the rail frame 10 of the carrier, both the rail frames 6 and 10 are fitted and connected.

The stretcher 5 has a pipe frame 60 formed into a rectangular shape on which the patient can lie supine, and a mounting plate 62 having a through hole 61 fixed thereon. The mounting plate for the trunk portion having the pillow portion 63 is tilted upward, and the sliding plates 17 provided on the lower surface are used to move and transfer between the respective rail frames.

65 provided on the operation panel 24 is a hot water mixing lever for the shower, 66 is a hot water mixing lever for the bathtub, 67 is a hot water supply amount control button, 68 is a thermometer, 69 is a switch for generating air bubbles from the bottom wall of the bathtub, 70 is a power lamp; 71 is a button for driving the rail frame 6 up and down;
72 is a shower head installed on the side wall of the housing.

The operation of the apparatus of the present invention constructed as above will be explained. When you want to bathe many patients continuously, first press the button 67 and the hot water mixing lever 6.
5 and 66, hot water at an appropriate temperature is supplied to the shower head 71 and bathtub 1. Then, the rail frame 2 is raised to the uppermost position by the lift switch 25. Thereafter, the screw rod 34 is rotated by the switch 71, and both the rail frames 6 are pivoted horizontally outward by the support frame 31.
At this time, the rail frames 2 and 6 are aligned on the same horizontal axis, and in particular, the rail frame 6 is located above the bathtub side wall by the connecting member 27. Even if a load is applied, it will not be accidentally lowered and folded.
Furthermore, both rail frames 6 may be provided with two motors 42 so that they can be folded separately.

The patient is transferred from the hospital bed onto a stretcher in a transport vehicle and taken to the bathroom. Immediately after the preceding patient is immersed in hot water in the bathtub 1, the rail frame 10 of the transport vehicle is connected to the rail frame 6 and washed with a shower. Shower cleaning involves washing with soap and rinsing with soapy water to cleanse the body.
When the preceding bathing patient leaves the bathtub 4 and transfers to the rail frame 10 of the transport vehicle for cleaning, the patient after washing is moved to the bathtub 4. At this time, the nurse confirms that the rail frame 2 is at the highest position, then releases the locking rod 80 with the lever 82 and moves the stretcher 5 to the bathtub 4.
Transfer it to the rail frame 2. The stretcher on the rail frame 2 takes a bath while moving up and down in the bath water without being accidentally moved or dropped by both locking rods 80. After cleaning, the patient is returned to the hospital bed in a transport vehicle.

Since the transport vehicle 5 is provided with a receiving tank 8 for storing waste water after washing the body, it is not necessarily necessary to connect it to the rail frame 6 of the bathtub and then perform the cleaning process, and if the preceding patient is connected to the rail frame 6 and is being washed. Use the waiting time to clean the appropriate space in the bathroom in advance, drain the accumulated water from the drain opening on the floor with a hose installed on the bottom wall of the tank, and make sure that the patient in front of you is not in the bathtub. When the person is transferred, a carrier is connected to the rail frame 6 and the person is transferred.

The case where the bathtub 1 constituting the device of the present invention is used alone will be described below. For example, infants with cerebral palsy are patients who have difficulty lying quietly on their backs on the moving stretcher 5. To bathe such patients in hot water, double rail frames 6 and 7 are required.
The rail frame 2, which is raised and lowered, is lowered to an intermediate position in the bathtub, and a screen plate (not shown) is placed above it. On the other hand, after the patient lying supine on the stretcher 5 of the transport vehicle washes his or her body in advance, the side of the transport vehicle 8 is fixed close to the side wall of the bathtub. While moving the patient to the bathtub, the nurse holds the patient and bathes the patient. The patient, who has warmed up in the hot water, is transferred onto a transport vehicle with the assistance of a nurse. Then, I wiped myself clean and returned from the bathroom to the bed.

When bathing a debilitated bedridden elderly person, etc., only one rail frame 6 is placed horizontally, and after the body is washed, the rail frame 10 of the transport vehicle is connected to the rail frame 6. Then, the stretcher is moved to the rail frame 2 in the elevated bathtub and lowered to take a bath. The subsequent bathing operation is performed using a continuous hot water bath procedure.

The device of the present invention having the above-mentioned functions is provided with a transport vehicle having a rail frame and a receiving tank on which a stretcher is placed so as to be transportable, and further provided with collapsible rail frames on both sides of the bathtub having a lifting rail frame. By configuring this collapsible rail frame to be connected to the rail frame of the transport vehicle, a. The equipment cost is lower than that of a continuous bathing device, and a large number of patients can be bathed more quickly.

(b) The cleaning tank and wiping tank are not fixed on the floor, but are installed on the transport vehicle, and the rail frame for transporting the stretcher is foldable using the walls on both sides of the bathtub, making it extremely easy for nurses to use. Since the bathtub can be changed to a separate bathtub, there is no need to provide a bathroom with a separate bathtub in addition to the bathroom of the continuous bathing device as in the past, and bathing assistance for patients can be easily and quickly performed.

(c) When the foldable rail frame is folded, it can be completely stored in the side wall of the bathtub without protruding above the upper edge of the side wall, and there is no risk of injury to nurses during their assistance work. When placed horizontally, the stretcher can be moved to a position above the upper edge of the side wall and aligned with the rail frame inside the tank, allowing the stretcher to move freely. Furthermore, the folding operation of the rail frame is activated by pressing a switch button and does not require any labor from the nurse. It has a strong structure and allows stable bathing of patients.
