DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shower bath device for patients who are unable to stand up, and in particular, when the patient lies down on a row of flexible elastic rollers and the patient is bathed in hot water, the upper side of the body and the lower part of the gap between the rollers are Warmer water is sprayed all over the body, and adjacent rollers swing in opposite directions for friction cleaning.
The present invention relates to a shower bath device in which rollers rotate in a bathing direction and a bathing direction when taking a bath.

2. Description of the Related Art Various devices have been proposed in the past for bathing patients, such as physically disabled people who have difficulty standing up, bedridden elderly people, and people in long-term hospital beds. Soaking in hot water in a bathtub is generally popular because it warms the whole body. However, in order to bathe in a bathtub, it is necessary to install a stretcher with transfer rails on the transport vehicle and a frame with transfer rails on the elevator inside the bathtub. Labor was a heavy burden. In view of this situation, shower baths have recently been proposed, but a sufficient cleaning effect can be achieved by simply spraying hot shower water partially over the patient's body from above or from the sides while lying on the patient's back on a bed plate. It was not designed to warm the whole body while washing the body, and the assisted labor of nurses was accompanied by almost the same pain as bathing in a bathtub.

The present invention overcomes the above-mentioned defects, and its gist is that the roller stand for bathing is formed of flexible elastic rollers, so that it supports the body softly and without any discomfort. The entire body lying supine on this table is sprayed with warm water from the upper and lower surfaces to wash it while being warmed, and the lower surface of the body is cleaned by friction using rollers.Mechanical transfer between the roller table and the patient transport means is used. This system does not require any equipment and reduces the caregiver's assistance work as much as possible. An embodiment of the present invention will be described below based on the accompanying drawings.

As shown in FIG. 10, the movable frame 5 is moved up and down by an arm 63 protruding from its lower surface, and a gas lift 65 is mounted between the arm and a mounting member 64 on the lower surface of the support frame. Furthermore, a lock cylinder 67 is installed between the arm 63 and the mounting member 66 on the lower surface of the support frame, and the lock cylinder 67 has a braking force due to the expansion force of a coil spring, and while loosening the lever 68 with one hand, the movable frame 5 is
When the lever 68 is lightly pulled up with the other hand, the movable frame 5 on which the patient is placed easily rises, and when the lever 68 is returned to its original position, the movable frame 5 stops steplessly at the desired tilted position.

FIG. 11 shows a patient transport means 70 connected to the roller stand 7. As shown in FIG. In this conveying means, a seat frame part 73 on which rollers 1 are arranged in rows is fixed to an underframe 72 having casters, and a foot frame part 74 and a back frame part 75 are pivotally attached to this. Although it is normally used as a trolley as shown by the solid line, it can also be used as a wheelchair as shown by the dotted line. This conveying means is suitable for the shower bath device of the present invention, but generally,
Even if a wheelchair or trolley is used, there is no problem in transferring the patient.

The operation of this device configured as above will be explained.

When the patient is transported to the bathroom, the transport means 70
The foot frame portion 74 of the roller stand 7 is held horizontally and is connected to the roller stand 7 by a suitable hanging member as shown in FIG. On the other hand, after closing the power supply with lead 80 on the side wall of the casing frame 3,
While pressing 1, the electromagnetic clutches 24 and 2
4' are engaged, the motor 15 rotates forward, and all the rollers 6 rotate in the counterclockwise direction (the bathing direction) in FIG. 10. At this time, the nurse lightly pushes the patient's back and the patient is transferred onto the roller table 7.
Release the pressed lead 81 at an appropriate transfer position.

When the patient lies supine on the roller table, the lock cylinder is loosened using the lever 68, and the roller movable frame is fixed in the inclined position shown in FIG. 2 while being lightly lifted with the other hand.

Then, the folded shower frame 9 is unfolded horizontally in order to supply the shower hot water prepared in advance. Then, by rotating the knobs 85 and 86, hot water is spouted from the upper and lower shower frames 9, 10, and 12. The shower frame 9 sprays water onto the upper surface of the entire body except the head, and the shower frame 1
Nos. 0 and 12 are sprayed upward from the gap between the rows of rollers 6 to wash the entire back surface of the head and lower limbs. 8
7 and 88 are hot and cold water valves 89 and 90 are thermometers. After warming up the body with hot water, stop the shower and wash the body with soap.First, the electromagnetic clutches 35, 35'
are engaged with each other to vibrate the roller 6. That is, the clutch arm 37, which is interlocked with the cranks 32, 32',
37' swing in opposite directions, and accordingly chains 30 and 30' reciprocate in opposite directions within a predetermined distance range. Both chains 30,3
Since the chain wheels 41 of the rollers meshing with 0' are sequentially arranged on the left and right, adjacent rollers swing in opposite directions. Therefore, the entire lower surface of the patient's body, on which the soapy water has adhered, is washed with soap by rubbing it with the soft peripheral surface of the roller. The upper surface of the patient's body is washed with soap by the caregiver. The head is carefully washed by the nurse using a separate hand shower. During this time, you may shower the area with a small amount of hot water. When soap washing is completed, the swinging of the roller is stopped using lead 83.

After removing dirt from the body by washing with soap, the shower water is sprayed on to cleanse the whole body.
Then wipe your whole body with a towel.

The used waste water, which has been washed all over the body with shower hot water, falls and collects in the receiving tank 11 below the roller gap and is discharged from the discharge pipe 31. Furthermore, the wastewater that has fallen into the receiving tank 13 flows down into the receiving tank 11.

When the shower bath is completed, the roller movable frame is returned to the horizontal position, and then the lead 84 is pressed and the roller 6 is rotated in the bath exit direction (clockwise in FIG. 10). In this case, the electromagnetic clutches 24, 24' are engaged and the motor 15 is rotated in the opposite direction. The patient transferred from the roller table 7 to the transport means 70 is returned to the bed in the hospital room in a sitting or supine position.

In the present invention, which has the above-mentioned effects, the table on which the patient's body is placed is equipped with flexible and elastic rollers made of sponge rubber, etc., so that there is no pressure on the lower surface of the body, and there is no pain or discomfort. Extremely comfortable. Therefore, when the rollers rotate and the body moves, the patient does not feel any pain.

Further, the rollers arranged in a platform shape are all rotated by a drive mechanism in the bathing direction and the bathing direction when the patient is mutually transferred between the roller table and the transport means, so that the nurse's assistance operation is easy. It does not involve painful labor and the number of nurses can be reduced.
Since the patient placement table itself constitutes a transfer mechanism, there is no need for a large bathing device for a stretcher on which a patient is placed, as in the past, and the area occupied by the bathing device can be reduced.

Furthermore, when washing a patient on a roller table with soap, the drive mechanism causes the adjacent rollers to swing in opposite directions to scrape away dirt from the lower surface of the body. There is no need to turn the patient over, and the caregiver only has to soap and wash the patient's upper surface.

Furthermore, the shower frame installed above the roller table showers the entire upper surface of the patient's body with hot water, and the shower frame installed below the roller table sprays hot water onto the entire lower surface of the patient's body through the gap between the rollers. The patient does not feel cold and chilly like in a conventional shower bath, but the whole body is warmed up like in a bathtub, and not only does the patient enjoy the pleasure of bathing, but the pine surge effect of the hot water jet is extremely large.

When using the above shower bath device, there is no need to worry about the uncleanliness of multiple patients using the same water repeatedly, as in the case of bathtubs, and in addition, there is no soap washing tank,
There is no need to install multiple tanks in parallel, such as hot water baths and cleaning tanks, and you can not only perform hot water spraying, soap washing, and washing with a single roller stand, but also All operations can be performed cleanly using fresh, unused hot water.
