[Prior art]

 Conventionally, as an air mat used to prevent pressure ulcers in bedridden patients and other chronic beds, many rod-shaped air cells are arranged in parallel on a rectangular base material. Place one air cell or group a plurality of air cells into one group, for example, divide into two groups of odd-numbered air cells and even-numbered air cells, and each group has a thin air pipe as an air supply path. A structure is known in which the air cells are communicated with each other and the air cells are continuously or intermittently and alternately injected and exhausted by a fixed program through the air pipe to expand and contract the air cells. (For example, U.S. Pat. No. 3,462,778, Japanese Patent Publication No. 55-16017, Japanese Utility Model Publication 56-6106, Japanese Utility Model Publication 56-18101, JP-A-61-48361, JP-A-62-181043, JP-A-62-18163. No. 181044, Jitsukaihei 3-41431, etc.), and some of the air cell molds are in the shape of a truncated cone or a short prism, and technology for controlling expansion and contraction individually (Jitsukai Sho 58-147 519) is also disclosed. In addition to the above-mentioned functions, in order to deal with pressure ulcer due to moisture and body heat caused by sweating of the patient, a structure is provided in which micropores are provided in the upper part of the air cell, etc. to leak the symptom. No. 55-18008, Japanese Utility Model Publication No. 3-41431). The purpose of the various air mats described above is to distribute body pressure to prevent pressure ulcers, prevent skin stuffiness, and change body position, and at the same time, it is also effective for pleasant sensation and good sleep by "fluctuation" operation. The movement of the air cell is programmed to have a constant continuous action according to its purpose, and it is possible to control the expansion and contraction action individually for a particularly long cell, and to maintain a constant action. There was no nursing air mat used for a completely different purpose while keeping its action stationary for a long time.

[0003]

[Problems to be solved by the device]

 As described above, in the air mat according to the related art, its effect on the prevention of pressure ulcer, which is the purpose thereof, is highly evaluated even in clinical cases. However, the most common daily tasks when caring for a bedridden person are postural change and defecation assistance.At the same time, there is a high need for home care, and many questionnaire results have consistently ranked the top for bathing care. It's a problem. It is widely known that taking a bath is the most effective method for preventing pressure ulcers, but it requires a lot of time and effort to carry it out, so it is the biggest problem in home care. For this reason, the inventors of the present application previously used an air tube formed to be approximately the same size as the bed surface in order to perform shower cleaning on the bed as a simple bathtub for nursing care in Japanese Utility Model Laid-Open No. 3-95365. A dam-shaped frame part and a dam band for partitioning at a predetermined position on the frame part.When cleaning a sick person, a waterproof sheet is covered on the upper part of the frame to form a cleaning tank. It has just disclosed the technology that allows partial cleaning of the necessary parts, such as only the lower abdomen and the lower abdomen, and the technology of forming a cleaning tank for the lower body and the whole body. However, what has been found clinically is that the target patient's height and lying position vary, so the position of the partition of the air mat cannot be specified, and the patient must be moved each time. It turned out to be a problem in use. Therefore, it is an object of the present invention to provide a new care air mat having a combined function of preventing pressure ulcers and assisting excretion, posture change, and bathing in total.

[Action]

 Next, the operation of the present invention will be described. When using the air mat for nursing care according to claim 1 of the present invention, when the toilet is inserted and removed and the diaper is replaced at a desired time, first confirm the location of the air cell located at the lower back portion, and then the portion concerned. If the three-way switching valve that communicates with one end of the air cell is rotated in the closing direction, the inflow of air into the air cell will be stopped and the air will be exhausted from one side at the same time. It is formed. At that time, if the sick person's body position is rotated to the half body position to lie down, the buttock will not sink into the gap and a space will be secured, which will make it easier to insert and remove the toilet bowl and replace the diaper. It's very convenient. After use, reverse the procedure to restore normal use.

In the air mat for care according to the second aspect of the present invention, the long air cell of this embodiment is normally laid under the air cell with air removed. In use, the air supplied from the air unit by operating the three-way switching valve can be supplied to the air cell at the same time or to only one side, so only one side is supplied. For example, by raising one side of the air mat, it becomes easy to tilt the lying position of the sleeping person. Furthermore, by repeating the action alternately, in addition to the action of the conventional air mat, a completely new function that can simultaneously perform the most important postural change for preventing pressure ulcers will be created. Further, air is simultaneously supplied to the air cells on both sides to lift the ends of the air cells. On the other hand, if the air of the cells corresponding to the desired portion of the air mat A surface, such as the lower abdomen, is discharged, only the desired portion is depressed Then, the cleaning tank is immediately formed. Next, in the cleaning work, it is necessary to insert in advance a waterproof sheet of vinyl or the like, which is large enough to sufficiently cover the part under the body to be cleaned. This can be easily done by raising the diaper sideways and changing the diaper. The above-described operation for exhausting air from the air cell in the lower part of the body is performed according to the procedure shown in the first embodiment. Next, the above-mentioned waterproof sheet 18 is sufficiently spread along the recessed portion on the air mat surface generated by the discharge of air, and the shape is adjusted to facilitate water collection. As described above, according to the present embodiment, a washing tank of a desired size is freely formed on the mat, and the function of being able to wash the shower while the sick person is lying down is added, which makes the care work extremely easy. Become.

In the air mat for nursing care according to the third aspect, when using the air mat A in this embodiment, the same operation as in the second embodiment may be performed. Air is injected into the frame part at the same time as the air cell is used, but since the expansion and contraction action does not occur after the injection, a cleaning tank is always formed in the peripheral part. Therefore, it is not necessary to operate the air cell again for cleaning. Next, in the cleaning operation, insert a waterproof sheet such as vinyl that is large enough to cover the area under the body to be cleaned, and then discharge the air from the air cell under the body. In this case, the exhaust operation and the like are performed according to the procedure shown in the above embodiment. Next, the above-mentioned waterproof sheet is sufficiently spread along the recessed portion on the air mat surface generated by the discharge of air to form a cleaning tank. As described above, according to the present embodiment, the action and effect of cleaning are the same as those of the above-mentioned embodiment, but in particular, in the present invention, the existing air mat is provided with a simple frame structure, We can provide economical air mats for nursing care.

In the air mat for nursing care according to claim 4, the frame part attached along the bottom side of the frame part provided on the peripheral part of the air mat is in a flat state excluding air during normal operation. Is laid in. When air is sent from the air unit during cleaning, the frame body is raised in two layers, and a deep-water reservoir can be prepared. Storing the desired amount of wash water in the water tank makes it easier to take a bath on the bed. Also in this embodiment, the operation of the air cell is as shown in the first embodiment, and the means for covering the waterproof sheet and the like are as shown in the second embodiment. After washing, wipe off water droplets on the body, remove the waterproof sheet in the reverse order of insertion, and then operate the three-way switching valve to evacuate the frame body to return it to a flat state, then use normal care air. Continue to use as a mat. As described above, according to the present embodiment, unlike the shower bath, the whole-body bath, which has the highest need, can be easily bathed on the bed due to the increase in the amount of water stored due to the easy preparation of the two-stage frame cleaning tank. As compared with the conventional bathing care, it will reduce the pain that the sick person will have when moving to the bathroom, will save labor for care during that time, and will significantly reduce overwork.

The present embodiment differs from the second and third embodiments in that another frame body portion 21 having the same configuration as the frame body portion is provided along the bottom side of the frame body portion 16 described above. The structure is attached in a two-story structure, and the structure thereof will be described below with reference to FIGS. A frame body portion which is substantially the same size as the frame body portion and is made of an airtight flexible tubular body along the bottom side bus line of the frame body portion 16 provided along the peripheral edge portion of the air matte A. 21 are attached in duplicate and are normally used with the air removed. The air pipe 5b and the three-way switching valve 17 can freely supply air to the frame body portion 21. Since a large amount of wastewater is treated as the drainage means in the present embodiment, it is desirable to provide a drain plug at the bottom of the waterproof sheet and quickly perform the wastewater treatment by the natural drainage method through the duct.

Next, its operation will be described. The frame portion 21 located on the lower side of the two-layer state is normally laid out in a flat state with air removed. At the time of cleaning, as the air is supplied by the opening operation of the three-way switching valve 17 and gradually expands, the peripheral walls become two layers, upper and lower, and a deep cleaning tank appears. As a result, the whole body can be bathed. Subsequently, a waterproof sheet is provided from the upper part of the frame body portion 16 to the recessed portion on the mat surface which is located inside the frame body portion 16 and is formed by discharging the air of the air cells 2, 2, ... If 18 is entirely covered and laid sufficiently, a simple cleaning tank is formed on the mat surface. The subsequent handling and the like are as shown in the previous embodiment. After washing, wipe off water drops on the body and remove the tarpaulin in the reverse order of insertion, then operate the three-way switching valve on the frame part 21 to evacuate and return to a flat state for normal care. Continue to use as an air mat.

As described above, according to the present embodiment, unlike the shower bath, the bed for the whole body bath, which is the most needed, unlike the shower bath, is provided by the increase in the amount of stored water due to the simple preparation of the two-stage frame cleaning tank. As compared to conventional bathing and nursing care, it eliminates the pain that the sick person suffers from moving to the bathroom, saves labor for nursing care during that period, and significantly reduces overwork. Leads to.

[Effect of device]

 With regard to the air mat for nursing care according to claim 1, it is possible to form a desired recess on the air mat surface by freely controlling the expansion / contraction mechanism of the air cell that constitutes the air mat, which is the most important point of care. Compared with the single action of conventional nursing air mats, it can be changed into a multi-functional type and its utility value is doubled, such as changing diapers and inserting and removing toilet bowls that require time and labor become extremely easy. In the air mat for nursing care according to claim 2, a new function for changing the posture is added, and a washing tank of a desired size is freely formed on the mat so that the sick person can be kept lying down. By creating a function that makes it easy to take a shower bath, it also has an excellent effect on preventing decubitus wounds and, as a result, contributes to a significant reduction in the nursing burden not only for the sick person but also for the caregiver, and for a long time. It is also effective in preventing malodor such as plaster odor and bed rest odor of bedridden sick people, etc., thus contributing to the improvement of the environment in the hospital room and the environment of the whole family. In the air mat for nursing care according to the third aspect, the construction is simple and the labor of operating the air mat during use can be omitted. In the care air mat according to claim 4, since a deep cleaning tank can be prepared to increase the amount of water stored, the whole body bath can be taken on the bed and even by one caregiver. This not only saves labor, but also reduces back pain due to overwork. As described above, the present invention makes it possible to provide total care for bedridden sick people, and because the mechanism is simple, it provides low cost, mass productivity, and economical air mat for care. Because it is possible, it will greatly contribute to the improvement of welfare.
