Description

[Detailed Description of the Invention] "Industrial Application Field" This invention provides a bed that allows sick people, such as bedridden elderly people, to easily take a bath without much trouble from caregivers, and a bed that does not dissipate odors into the room. This invention relates to a bed that allows the patient to defecate even when operated by the patient himself.

``Prior Art and its Problems'' The average lifespan of the Japanese people continues to increase year by year, and they are now becoming one of the longest-lived societies in the world, but on the other hand, the existence of bedridden elderly is becoming a social problem. The reason for this is that unbearable burdens and pain have become commonplace for both caregivers and the elderly. Bathing is the most burdensome task, and is often beyond the capabilities of inexperienced caregivers. Therefore, it can be done safely at home instead of taking a bath.
People simply wipe their bodies, but it is difficult to achieve the same effect as bathing, and as a result, the sick person's grime builds up, and the muscles, blood vessels, nerves, etc. atrophy, causing degeneration. The contamination of the private parts is particularly severe.

Furthermore, since bedridden elderly people have great difficulty in defecating, various beds have been developed that allow them to defecate on the bed. However, these beds inevitably emit bad odors into the room, so they cannot alleviate the psychological pain caused by the patient's pain.

This invention aims to solve these problems all at once, and provides a bed with a bathtub that allows even inexperienced caregivers to bathe bedridden elderly people easily and safely, and a bed that does not dissipate odors into the room. To provide a bed with a bathtub equipped with a device that allows one to defecate by one's own operation.

``Means for Solving the Problems'' That is, the present invention provides a bathtub that is installed under the floor of a bed so that it can slide freely in the horizontal direction, and that the bathtub is equipped with a mat that moves up and down in the bathtub while the human body is lying down. The bed is provided with a tilting means for easily transferring the sick person from the bed to the bed, and the bed is arranged so that it is normally in a horizontal state but is bent in the bathtub. The tub is tiltable to facilitate transfer from the mat to the bed, and by sliding the bathtub and the bed, a part of the mat and a part of the bed are polymerized, and the sick person can be transferred from the bed to the bed or from the bed to the bed. It is characterized by being configured to be moved.

"Example" Next, an example of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, in which a bed 1 and a bathtub 2 are installed so as to be horizontally slidable, a patient is placed in the bathtub 2, and a mat 3 (see FIG. (not shown) is shown below.

The bed 1 and the bathtub 2 are as shown in FIG.
Guide members 5 facing in the lateral direction of the bathtub are slidably fitted into guide rails 4, 4' formed on the inner surfaces of both sides of the bed head and foot. The upper and lower sliding surfaces of the guide rail are formed in recesses, and a plurality of wheels 6 are fixed to the recesses, and the recesses formed on the upper and lower surfaces of the guide member fit into and abut the wheels, and slide between the bed and the bathtub. It is designed to be easy.

As shown in FIGS. 3 to 6, the mat is made up of two frames 7 and 8 connected by a crossbeam 9, and a mat cloth 10 formed in a lattice shape is attached to this frame. . The matte cloth is best made of a soft material with a surface treatment so that it will be smooth and have no resistance even when the patient's skin is rubbed. For example, use a velvety cloth with electrostatic flocking. It is better to do so. A large number of through holes 18 are perforated in the mat cloth 10, so that the ultrasonic waves generated by the heating circulation device and the air bubbles that massage the skin surface pass through these through holes and evenly hit the human body. There is.

On both sides of the frame, as shown in FIGS. 3 and 5, there are cylindrical bodies 1 for bending or extending the pine.
1 and 12 are fixed. A movable barrel 13 is fitted into this barrel, the rear end of the movable barrel is connected by a spring 14, and a hook 15 for hooking a rope is fixed to the tip. The movable cylinder 13 has wheels 16a, 16b,
16c is fixed, and this wheel abuts against the cylinder to facilitate movement within the cylinder. In addition, 1 in the figure
Reference numeral 7 denotes a stopper which has the role of pushing up the slope of the tip of the movable cylinder 13, and is designed to lock the tip of the movable cylinder at this position.

As shown in FIG. 7, cylindrical recesses 19 are formed at the four corners of the bathtub, and a cylinder 20 having a small diameter portion at the lower end and a threaded portion on the inner peripheral surface is fitted into the recess. The bottom portion rotatably contacts the lower surface of the cylindrical recess via a ball bearing 21.
The outer peripheral surface of the small diameter portion at the lower end of this cylinder is formed into an arcuate recess 22 having a threaded portion, and the threaded portion and the drive gear 23 mesh with each other. This drive gear is connected to a drive shaft of a motor when the mat is automatically moved up and down, and connected to a manual handle when the mat is moved up and down manually. An elevating tool 24 having a threaded portion at its tip is screwed into the cylinder, and a rope 25 at the other end connected to a mat is guided by rollers 26 and inserted into the cavity inside the elevating tool. has been done. The tip of this rope passes through the small diameter portion of the cylinder and the lower surface of the cylindrical recess and is fixed to the lower surface of the corner of the bathtub. Fixation is achieved by fitting and fixing a metal fitting with a threaded portion on the outer peripheral surface to the tip of the rope, and screwing a nut into this metal fitting. With this configuration, when the drive gear 23 is rotated, the cylinder 20 is rotated, thereby causing the lifting tool 2 to rotate.

To transfer a patient from a bathtub to a bed, as shown in Figure 8, all lifting devices are raised to the height of the bed, and then the lifting device 24' furthest from the bed is lowered until a suitable slope is formed. After raising it 24', 24'', the patient should roll it over and transfer it to the bed.

The bathtub of the present invention is equipped with a bathtub heating and circulation purification device 28 that allows the user to take a bath at any time of the day without changing the bathtub and cleans the body just by taking a bath. This heats the bathtub through the suction pipe 29, as shown in FIG.
The bathtub is introduced into the circulation device 28, filtered and heated, and is then squirted into the bathtub along with bubbles from an ultrasonic nozzle through a spouting pipe 30.

The bathtub heating and circulation purification device 28 includes a removable filtering means for pumping and filtering bath water from the bathtub;
The bath water is equipped with a means for pumping and heating the bath water, a temperature sensor for controlling the heating means, and a means for spouting the filtered and heated bath water into the bathtub along with bubbles by an ultrasonic nozzle. Contains a bath water purifying mineral agent that has the effect of suppressing the precipitation and coagulation of organic matter, sterilization, deodorization, and the generation of steam. The details are described in the specification of Japanese Patent Application No. 4402/1982 and the specification of Japanese Patent Application No. 220945/1989 filed by the applicant of the present invention. As described above, one of the characteristics of the bathtub of the present invention is that it contains a bathwater purifying mineral agent, and by mixing the bathwater purifying mineral agent in this way, the generation of steam and odor can be avoided. As a result, the bathtub can be slidably attached to the bed.

The bathwater purifying mineral agent of the present invention is obtained by dissolving vermiculite in which mica-based minerals (preferably black mica) have weathered or soil in which this vermiculite has further weathered in an aqueous solution of an inorganic acid (for example, sulfuric acid or hydrochloric acid). This is an acidic additive containing various types of metal salts and non-metal salts as main components. According to this additive, removal of precipitation of organic matter dissolved in bath water, sterilization, replenishment of minerals, and removal of agglomeration of insoluble matter can be achieved all at once.

Furthermore, even if a sick person urinates in the bathtub, the action of the bathtub purifying mineral agent decomposes the organic matter, makes it insolubilized, and makes it odorless. is filtered out. Therefore, even in the above case, the bath water is automatically purified without being replaced, and it goes without saying that this is a great effect as a bathtub for patients.

As shown in FIGS. 6 and 12, a drop weir 31 is removably fitted into the bathtub.
1, a hair washing chamber 32 is formed. Reference numeral 33 in FIGS. 1 and 6 is a grip rod attached to a recess on both sides of the bathtub, so that the patient can grasp the rod to stabilize his or her body.

Ru. The toilet bowl 49 that has been raised in this way is placed on the bed frame 5.
A stopper 55 fixed to the frame 54 so as to be removable and removable is inserted into a hole in the frame 54 against the force of a spring 56, and when the pressure is released, the stopper 55 is fitted into a recess 57 formed in the box body by the force of the spring 56. I'm starting to do that. In the figure, reference numeral 107 denotes movable handrails placed on both sides of the bed, which the user grabs when using the toilet.

The toilet bowl has a hot water nozzle 58 for cleaning the anal area.
, a warm air nozzle 59 that dries the anal area integrally formed with the hot water nozzle, a foam jetting pipe 60 that acts to prevent odor, and a vacuum device 108. First, when a sick person relieves himself,
Foam 102 for preventing odor is ejected, the user relieves himself in the foam, and the feces is wrapped in foam. After the user finishes using the toilet, the foam-wrapped stool is immediately stored in the vacuum tank 62 through the flexible vacuum pipe 61. In this way, the feces are made odorless by the foam and are stored in the sealed vacuum tank 62 together with the washing water, etc., which prevents the release of bad odors to the surroundings, prevents the feces from splashing, and prevents the feces from splashing. The lubricating effect prevents feces from sticking to the toilet bowl.

When a bed is equipped with a toilet bowl like the one mentioned above, even bedridden elderly people can relieve themselves on their own or with a little assistance, which not only makes it easier for the attendant, but also provides psychological benefits such as a sense of security to the sick person. The effect is also large.

In the above embodiment, the other end of the hot water nozzle is
It is connected to the bath water heating circulation purification device.
With this configuration, just by twisting the tip of the nozzle, moderately heated hot water will be ejected, making this device extremely inexpensive to construct, and the deodorizing action of the bath water purifying mineral agent further makes stool odorless. Achieved on the wall.

When the toilet bowl 49 is finished, the toilet bowl 49 is lowered together with the box, and as the upper mat 46 is lowered, the partition mat 4 is lowered.

It is preferable to equip a video phone that allows family members or caregivers to talk while looking at each other's faces by taking pictures with the video phone camera 115.

If possible, the recipient of these alarm systems and video calls should have a regional monitoring center that monitors bedridden elderly people in the area, and should receive appropriate instructions from a doctor, care worker, etc. stationed at this center. This will facilitate the creation of a comprehensive regional welfare system.

"Operation" Next, the operation of the present invention will be explained with reference to FIG.

When bed 1 is slid, bathtub 2 appears. The bathtub 2 is covered with a lid (not shown), which is adapted to be attracted to the bottom surface of the bed by the action of a magnet when the bed is slid. The mat has hook 1 of the movable cylinder on one side.
It is supported by a synthetic resin rope 18 fixed to 5,
It is fixed to a rope from the moving cylinder on the other side.
Then, when the elevators 24, 24' in the movable cylinder are raised manually or by a motor, the synthetic resin rope 25 is pulled, so that the mat 3 is placed in a horizontal state at the same height as the bed 1. Then,
After sliding the bathtub toward the bed as shown in FIG. 14, the bed is tilted at a predetermined angle toward the mat as shown in FIG. 8 or 9, and the patient is rolled and transferred onto the mat. Then, after sliding the bathtub out of the bed, the drive gear is rotated in the opposite direction to lower the mat into the bathtub, and the movable cylinder 13 passes through the joint between the cylinders 11 and 12. The head then moves to the foot mat, and the mat follows the shape of the bottom of the bathtub and bends to hold the head above the water. After washing the body and hair and thoroughly soaking in hot water, the mat is raised in the same manner as above. The mat is placed in a horizontal state at approximately the same height as the bed, and after the bathtub is slid toward the bed, the elevating tool 24' farther from the bed is raised to tilt the mat 3 toward the bed. Next, after rolling the sick person from Matsuto 3 to Betsto 11,
The mat 3 is made flat and lowered, and the bed 1 is slid and combined with the bathtub 2. When the power is turned off, the lid of the bathtub 2 loses its magnetic effect and falls off the bottom surface of the bed and onto the bathtub.

"Effects of the Invention" As stated above, the bed with bathtub of the present invention has the following features:
The bed and the bathtub are fixed in a slidable manner, and the bathtub is equipped with a mat that moves up and down within the bathtub, and the mat and bed are configured to be tiltable, so that bedridden elderly people can be cared for by one caregiver. However, the patient can be easily and safely moved from the bed to the bed and from the bed to the bed and bathed. Also,
If a bath water purifying mineral agent is mixed into bath water, even if a sick person becomes incontinent, urine and feces will be decomposed and insolubilized.
If the bath water is made odorless and ejected from a hot water nozzle, it will be possible to use the toilet without dispersing the bad odor into the room, thereby eliminating psychological problems caused by the patient's scars. It can also reduce pain.
