2. Description of the Related Art Conventionally, bedridden elderly people and bedridden patients
As a method of putting a cared person such as a disabled person in a bath, two or more caregivers are required to hold the cared person for bathing, which is a heavy labor for the cared person. For this reason, various nursing beds that also serve as bathtubs have been proposed so that the care recipient can take a bath while lying in the bed without moving the care recipient. The beds for nursing care such as mattresses have bed beds that can be moved up and down in the bathtub so that they can take a bath while lying on the bed. For example, the one described in JP-A-5-7607 is capable of moving up and down a waterproof mat, which is a bed, into a bathtub via a lifter including a link mechanism, and is disclosed in JP-A-5-237160. In the other, a waterproof water mat, which is a bed, can be moved up and down in the bathtub by an elevating device using four hydraulic cylinders. In addition, JP-A-6-25
In the one described in Japanese Patent No. 807, a pair of hydraulic lifts and a rack-and-pinion type lift mechanism make it possible to raise and lower a support plate on which a mattress, which is a bed, is loaded in a bathtub.

[0003]

In order to provide the above-mentioned bed in the bathtub so that the bed can be lifted and lowered, a mattress or water mat which is a bed is used in this type of bathtub / care bed.
Since a lifter consisting of a link mechanism and a lifting device using four hydraulic cylinders, or a mechanical device such as a pair of hydraulic lifts and a rack-and-pinion type lift mechanism was used, the structure was complicated and the cost increase was avoided. There wasn't. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a practical and low-cost nursing bed that also serves as a bathtub.

[0004]

In order to achieve the above-mentioned object, in the bathtub / nursing bed according to the present invention, a rectangular appearance is expanded in the frame body of the bathtub 1 by injecting / draining water.・ A pair of water mats 2 and 3 that can be contracted, the upper part for bed and the lower part for bed and bath,
A heat-insulating sheet 5 is provided to arrange the upper and lower layers in two stages, and an expandable and retractable bag 4 that allows water to be injected and discharged under the bath 1 and is injected into the bag 4 in communication with the bag 4. A pedestal 8 in which a heater 6 having a temperature thermostat for heating water and a circulation pump 7 in communication with the heater 6 are installed,
Inside the water mats 2 and 3 are arranged so that the bath tub 1 is arranged so that water can circulate through the bag 4 and the water mats 2 and 3 and the bath tub 1 by the operation of the pump 7. When the cared person is able to lie on the bed by stopping the water filling and the circulation of water in the upper water mat 2, the warmed water in the lower water mat 3 is circulated with the warm water circulated and heated and the upper water filled with water. The caretaker is allowed to enter the bath due to the overflow of water into the bathtub 1 due to the contraction of the lower water mat 3 by the weight of the mat 2, and the hot water can be circulated in the bathtub 1.

As a result, in the bed for nursing care combined with the bathtub of the present invention, the upper water mat 2 and the lower water mat 3 are filled with water and the upper water mat 2 for the bed is lifted so that the cared person can lay down on the bed. A care receiver who has laid down and put on clothes can lie down on the bed. At the time of bathing, the temperature thermometer provided in the heater 6 is set in advance to an appropriate temperature for bathing, and the heater 6 and the circulation pump 7 are energized and operated to heat the water in the bag 4 filled with the water in the pedestal 8. While passing through the vessel 6, the pump 7 is circulated in the lower water mat 3 and the bag 4 by heating. When the circulating water reaches an appropriate temperature, the circulation is stopped, the caregiver's clothes are removed, and the weight of the water causes the warm water in the lower water mat 3 to overflow into the bathtub 1, causing the lower water mat 3 to contract. The care receiver can be warmed sufficiently by allowing the care receiver to take a bath and circulating hot water in the bathtub 1. When washing the head / body, the circulation in the bathtub 1 should be stopped.

After washing and draining the body, water is supplied to the bag 4 so that the lower water mat 3 cannot overflow into the bathtub 1 and is circulated to the lower water mat 3 so that the lower water mat 3 can be circulated. To make the bed in the original state. Next, the care receiver and the mat are thoroughly wiped, sheets are laid, clothes are put on, and the person is laid down. In this case, even if the lower water mat 3 is heated while the heater 6 is energized, the heat is blocked by the heat insulating sheet 5 and the upper water mat 2 is not heated.

In the above, the circulation pump 7 in the gantry 8
It is desirable that the shower nozzle 9 is made to face the upper part of the bathtub 1 so that the care recipient can be showered through the pipe from. As a result, the circulation pump 7 is also used as a shower to wash the care recipient's head and body, and then the care recipient's head, body, mat, bathtub, etc. can be easily cleaned by the shower. .

The use of the nursing-care bed that also serves as the bathtub will be described below. Prior to the installation and use of the bath-bed and nursing-care bed, the upper water mat 2, the lower water mat 3 in the bath 1 and the bag 4 in the pedestal 8 are in a contracted state. For installation and use, first close the bathtub hot water supply valve V ₄ , drainage valve V _6: bathtub circulation valves V ₅ , V ₇ after piping. Then, open the upper water mat circulation valve V ₃ , the lower water mat circulation valve V _2, and open the water supply valve V ₁ . As a result, the upper water mat 2 and the lower water mat 3
The bag 4 and the bag 4 are filled with water and are filled with water, and are in a state of FIG. That is, since the care-receiver is in a state of being able to lie down, the sheets are laid and the care-receiver is laid down (see FIG. 2). In the figure, comforters and blankets are omitted for convenience.

For bathing, the lower water mat circulation valve V ₂ is opened and the remaining valves are closed. Then, a temperature thermostat (not shown) of the heater 6 is set to an appropriate temperature for bathing. Further, before the time required for the water in the lower water mat 3 and the bag 4 to reach an appropriate temperature, the heater 6 and the pump 7 are turned on to operate them. As a result, the water in the lower water mat 3 and bag 4
_{P 2, P 3, P 10} , P 12, warmed while circulating through the P ₁ becomes hot water.

When the hot water in the lower water mat 3 and the bag 4 reaches an appropriate temperature, the pump 7 is stopped and the lower water mat circulation valve V ₂ is closed to stop the circulation into the lower water mat 3 and the clothes of the care recipient. And take the sheets and open the bathtub hot water supply valve V ₄ . As a result, the hot water in the lower water mat 3 will have the weight of the cared person on the upper water mat 2 (in this case, the pillow will be changed in advance to raise the head of the cared person) and the upper water mat will be full. While the lower water mat 3 is contracted by the weight of 2, the warm water inside overflows into the bathtub 1 through the pipe P ₈ and gradually sinks, so that the care receiver enters the bathing state (see FIG. 3). At this time, the pump 7 is operated to open the bath circulation valves V ₅ and V ₇ to circulate the hot water from the bag 4 through the bath 1. When the care recipient becomes warm, the pump 7 is stopped and the bath circulation valves V ₅ and V ₇ are closed to wash the care recipient's head and body. After washing, open the drain valve V _{6 so} that the hot water in the bath 1 will be discharged. Next, open the shower valve V ₈ and operate the pump 7 to discharge the hot water in the bag 4 from the shower head 9,
Clean the care recipient's head, body, mat, bathtub, etc.

(See FIG. 2). After that, the care receiver and the mat are thoroughly wiped with sheets and clothes are put on. Then, the heater 6 and the pump 7 are turned off, and all the valves are closed. At the next bathing, the process from (0017) is repeated. In addition, in the above, when the upper water mat 2 is in a raised position due to full water of the lower water mat 3 and the care recipient is in a bed rest state, when the lower water mat 3 is filled with hot water, the heat insulating sheet 5 is It prevents heat from being transferred to the upper water mat 2 and does not interfere with a comfortable bed rest. In addition, an air heater may be used to dry the head / body or mat of the care receiver.

In this nursing bed for combined use of bathtubs, the upper and lower water mats 2 and 3 are arranged in the bathtub. Therefore, the waterproof and flexible sheet material and vinyl sheet or the like constituting the mats are also covered. It has the advantage of not requiring much strength, and even if the water mat in the bathtub or the bag in the rack is torn, it will not overflow into the room in which it is installed, and the room in which it is installed only needs to be prepared for water supply and distribution and electricity. Further, the bath-bed and nursing-care bed of the present invention can be modified in various ways within the scope not departing from the gist of the present invention, regardless of what is shown in the above-mentioned embodiment.

[0021]

According to the nursing bed for combined use of the bathtub of the present invention as set forth in claim 1, a care recipient such as a bedridden elderly person, a bedridden patient or a disabled person is allowed to take a bath without moving from the bed. Therefore, it is possible to significantly reduce the labor and burden on the caregiver such as the helper, and also to lighten the burden on the cared person. In addition, when raising and lowering the bed such as a mattress in the bathtub, the rise is caused by pouring water into the lower water mat, and the lowering is caused to contract the lower water mat by the weight of the care recipient and the fully filled upper water mat. Therefore, unlike the conventional case, a mechanical structure such as a hydraulic cylinder or a link mechanism is not required, and a simple structure can be provided, and it is possible to provide a practical and low-cost bath bed / care bed.

According to the second aspect of the present invention, after the care recipient is washed by using the circulation pump also as a shower, the care recipient, the mat, the bathtub, etc. can be easily cleaned by the shower.
