As a third solution, handrail plates (9) are connected to extensions (18) of both lateral ends of the foot-side mat portion that bends and stretches according to the ups and downs of the bed and changes into an armrest shape at the time of ups and downs. , and connected to an appropriate position of the back side mat part (2) so that the raising and lowering of the bed and the return operation are linked together.

Then, as a fourth solution, a U-shaped member (19) that reciprocates in the vertical direction of the bed in conjunction with the bending portion (14) of the mats on the back side and the buttocks side when the bending portion (14) is lowered or raised and restored. The rolling support point rotating parts (6) for the foot side and the back side push up or support the mat bottom plate side of the mat part on the back side and the foot side through the link (20) while rolling. By changing the distance from the bed hoisting and return operation fulcrum (1), etc., a rolling support point mechanism that assists and complements the increase and decrease of the bed hoisting angle is installed at both lateral lower portions of the bed underframe (5). established.

As a fifth solution, the opening and closing of the buttocks mat (12) can be selected not only from fully open and fully closed but also from half open and slightly open, and a splash prevention cover (15) for flushing hot water similar to a seat-type flush toilet is provided. , it is installed below the buttocks part mat (12) so that the part of the mat corresponding to the position of the large excrement outlet of the buttocks is directly above when the bed changes into a chair shape, and furthermore, the upper surface of the scattering prevention cover is partly A waterproof cushioning material (17) is attached with an inclination and shape that matches the bottom plate surface of the mat from the buttocks side mat part to a part of the back side mat part (2) near the buttocks, and a lifting device ( 21) is provided so that the scattering prevention cover (15) can be raised and lowered to maintain shape matching and prevent water leakage.

As a sixth solution, a washing hot water spray device (7) and a drying air blowing device (8) are installed, and the injection ports and injection nozzles for the washing hot water and the drying air blowing are provided on the anti-scattering cover (15). A plurality of nozzles are arranged at appropriate positions such as the inner periphery, and the injection port and the injection nozzle can be selected according to the purpose of cleaning.

Then, as a seventh solution, when the bed rises and falls and changes into a chair shape, the foot-side mat portion (4) descends and bends into an L shape, and both sides of the buttock-side mat portion (3) lie down. Extensions (18) at both lateral ends of the foot-side mat portion and the connecting handrail plate (9) are bent and raised to form an armrest shape to support the body, and further the foot-side mat portion is provided. (4) The three sides of the bed frame (5) on both sides and the front side can be opened and closed or attached and detached.

As an eighth means for solving the problem, when the bed user stands up, a mechanism is adopted in which the lower buttocks side mat portion (3) is raised to push up the buttocks.

The action of the first problem-solving means is that the buttocks side mat part (3) and the foldable mat part (10) are made of flexible rebound resilience water-resistant material with a large number of holes in the vertical or near-vertical direction. , the mat can be bent at an acute angle, and the raising and lowering operation of the mat is performed smoothly, and the method of opening and closing the buttocks portion mat does not require a complicated opening and closing mechanism for preventing itching of the skin of the buttocks of the bed user. It is possible to jet washing hot water from multiple directions toward the vicinity of the body excrement outlet after excretion without worrying about the wetness of the body. improve to

Next, the action of the second to fourth solution means is to provide the undulating and return operation support point (1), extend the lateral end portions (18) of the foot side mat portion that changes into an armrest shape, and connect the hands. The contact plate (9) is connected to the dorsal mat part (2), and combined with the U-shaped material (19) and the link (20) of the rolling support point mechanism to form a single actuator. It becomes possible to interlock the raising and lowering and the return operation of the bed with a chisel. Furthermore, the body on the chair-like bed has a low buttocks and bends the knees in a posture suitable for excretion.

Further, the action of the fifth and sixth problem-solving means is that by arranging a plurality of jetting ports and jetting nozzles at appropriate positions, it is possible to spray large and small excretions from the body in a plurality of directions toward the periphery of the outlet and the surrounding mat. It is possible to wash and dry the body and dry it according to the size of excretion and the washing place, and it is possible to wash the opening and closing mat itself by selecting the opening and closing angle of the buttocks part mat (12), so that the body and the mat can be kept clean. . In addition, a scattering prevention cover (15) that matches the shape of the bottom plate of the mat when the bed is changed into a chair is installed, and after collecting the washing hot water without leakage, existing technology can be used according to the situation of the bed installation place. It can be transferred to flush toilets, septic tanks, sewers, etc. for treatment.

Then, the action of the seventh and eighth problem-solving means is that when moving from the chair-shaped bed to the outside of the bed, the buttocks are pushed up and the body is supported by the armrest-shaped handrail plate (9) to stand up. It is possible to move by walking from the bed, which is supported and the feet are low and open, and the burden of moving outside the bed can be reduced.

As described above, by using the care bed according to the present invention, when the care recipient wants to excrete, the mat simply rises and falls, the buttocks side mat part (3) tilts, and the buttocks are lowered to excrete. In addition, since the position of the buttocks is inclined low, it is easy to aim at the target for spraying hot water and water, and furthermore, the splashes of dirty hot water after washing with hot water will also easily fall downward according to gravity, so after excretion. cleans and dries the body and the mat by spraying hot water and water onto the surrounding mats from multiple directions toward the vicinity of the excrement outlet of the body without worrying about the wetness of the mat. , you can play the original role of the bed as bedding. In addition, the feet are freed, and the function of standing up assistance is also provided, which reduces the burden of moving between the bed and the outside of the bed.

In addition, the problem of putting on and taking off underwear such as a diaper during excretion, which is troublesome for the care recipient, can be solved by wearing nursing care pants with holes instead of diapers. This eliminates the factors that hinder the spread of nursing care beds, and eliminates the pain and burden associated with diapers on care recipients and caregivers.

A perspective view of the nursing care bed of the present invention when the bed changes into a chair shape. A perspective view of the bed from diagonally below showing the main hoisting mechanism in the state of FIG. The side view of FIG. 2 showing the positional relationship of the anti-scattering cover The side view just before the state of the mat shown in FIG. 3 returns to the state of the normal mat.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a mode for carrying out the invention will be described based on an embodiment with reference to the drawings.

The buttocks side mat part (3) and the mat part (10) that bends when the bed is raised and lowered are made of a flexible, repulsive, water-resistant material with many holes, except for the outer circumference and the latch fixing part, so that the bed is shaped like a chair. The mat bottom plate of the perforated mat, which is located within the range of being accommodated in the scattering prevention cover (15) when it changes to a metal mesh, is made of a rust-proof material. The shape of the mat holes is not limited to a round shape, but may be other shapes, and the number, diameter, and shape may not necessarily be uniform or the same, and may not be the same as the holes in the bottom plate of the mat. Further, the shape of the opening/closing mat portion is not limited to an oval or ellipse, and may be rectangular or trapezoidal. See FIGS. 1 and 2.

Further, the fulcrum (1) for raising and lowering and returning the bed is provided on the bottom plate side of the buttocks-side mat (3) so that the bent portion (14) between the buttocks-side and back-side mats is lowered, and The foot side mat part that bends and stretches according to the raising and returning operation of the bed and changes into an armrest-shaped handrail at the time of raising and lowering. In (2), the mat is connected to the balanced position of both lateral ends so that the raising and lowering and the return operation of the mat are coordinated. See Figure 1.

In addition, when the bed is raised and lowered, the movement of the U-shaped member (19) causes the bottom plate sides of the mats on both the back and foot sides to roll. A rolling support point mechanism is provided at the bottom of the bed frame (5) on both sides of the bed to assist and complement the increase and decrease of the hoisting angle of the bed by pushing up or supporting each of the support point rotating parts (6) while rolling. . See Figure 2.

As a result, when the bent portion (14) of the dorsal and buttock-side mat portions is lowered by a single actuator, the U-shaped member (19) moves toward the leg side of the bed at the same time, and the link (20 ), the rolling support point rotating part (6) for the back side mat part pushes up the back side mat part (2) and raises it, and the rolling support point rotating part (6) for the foot side mat part moves the foot It descends while supporting the side mat part (4), and in parallel with this, the handrail plate (9) acting as a link is pushed up by the back side mat part (2), and both sides of the foot side mat part go up. By continuing to press the extended part (18) of the lateral end, the foot-side mat part (4) is pushed down, and the foot-side part interferes with the floor or the stopper near the floor and bends into an L shape, thereby lying down. The handrail plate (9), which had been in a straight line state, rises and forms an armrest shape together with the extension part (18) of the foot-side mat portion to support the body. In this rolling support point mechanism, the U-shaped members may be arranged in two stages, and a rack gear and a pinion gear may be combined so that the movement directions of the upper and lower U-shaped members are opposite to each other.

The fulcrum (1) for undulating and returning action here may or may not be at a position that halves the entire length of the bottom of the buttocks side mat (3), but if the fulcrum (1) is provided near the center, the buttocks The height of the bent portion (13) between the side and foot side mats increases, and if the shape of the upper surface of the anti-scattering cover is matched to this, when the bed returns to a flat mat, the anti-scattering cover (13) on the side of the foot ( 15) Since the upper surface and the bottom plate of the mat interfere with each other, it is necessary to raise and lower the scattering prevention cover. However, since the bending of the knees becomes shallow in the excretion posture, an elevating device (21) is installed. For the sake of convenience of explanation, a diagram using a dedicated actuator is shown, but it is better to use a link or the like on the U-shaped member (19) for undulating and returning operation so that it can move up and down by interlocking operation. . See FIG.

In addition, the undulation of the mat means the same as the undulation of the bed, and the U-shaped member (19) for interlocking the undulation and return operation of the bed is of a type that avoids the scattering prevention cover (15) at the center of the bed. If available, it may be a U-shaped or square-shaped member or another type of member.

Next, a scattering prevention cover (15) similar to a flush toilet bowl is provided under the buttocks part mat (12) so that when the bed changes into a chair shape, the bottom of the large excrement outlet of the buttocks becomes the center, and the cover is raised and lifted. The upper surface, except for a part, is inclined and shaped to match the bottom plate surface of the buttocks side mat part (3) to a part of the back side mat part (2) near the buttocks, A waterproof cushioning material (17) is installed to maintain conformity and prevent water leakage, and the size is set so that it can be accommodated even if the open/close mat part is fully opened. I made it possible to connect to a septic tank, a flush toilet, etc. according to the situation. The degree of opening and closing of the buttocks mat (12) can be selected, and the buttocks mat (12) can be washed according to the size of excretion. 14) made it possible to wash the mat part. The opening and closing method of the opening and closing mat part here is a double-opening type that takes advantage of the flexibility and elasticity of the mat, and has a mechanism that opens and closes manually or electrically. See FIGS. 1 and 3.

In addition, a washing hot water spray device (7) and a dry air blowing device (8) are installed near the head side rail frame of the bed, and the hot water washing and dry wind blowing devices and blowing nozzles are provided around the inside of the scattering cover. were placed in multiple locations. In addition, the three sides of the bed frame (5) in the lateral side of the foot-side mat portion and in the toe direction are made into a door type or a detachable insertion type to facilitate walking to the outside of the bed. See Figure 1.

Furthermore, the bending part (14) between the buttocks side and the back side mat part and the U-shaped material (19) for interlocking are connected by the link (20), but the interlocking operation connecting part on the U-shaped material side. (16) can be switched between connection and disconnection, only the bending portion (14) is raised, the rolling fulcrum mechanism is stopped, and the buttocks are pushed up to prevent standing up from the chair-like bed. Made it support. See FIG.
