Description

[Detailed Description of the Invention] The present invention relates to an improvement of a pinerest with a defecation device that allows the user to defecate while lying down.

A pinerest with a defecation device has been developed that allows seriously ill patients and elderly people who are unable to get up to defecate while lying down.

Generally, this type of pine tress is constructed as follows.

That is, an insertion portion opening in the width direction and the side surface of the mattress body is formed, and a through hole communicating with the insertion portion and opening in the upper surface of the mattress body is bored.

When using the toilet, the toilet is inserted into the insertion part so as to face the through hole, and after the toilet is taken out from the insertion part, the closure body is inserted and held in the through hole.

By the way, conventionally, in order to insert and hold the closing body into the through hole, a link mechanism is provided in the insertion portion, and the link mechanism pushes up and holds the closing body.

However, according to such means, the link mechanism consists of many parts, resulting in a complicated structure, and
The operation of this link mechanism is also not easy.

Furthermore, since the closing body held by the link mechanism does not have cushioning properties as strong as the material of the closing body, the part of the through hole into which the closing body is inserted becomes harder than other parts, which reduces the performance of the pine tress. There were problems such as a decline in

The present invention was developed based on the above-mentioned circumstances, and its purpose is to simplify the structure by providing an air bag in the insertion section and holding the obturator inserted into the through hole with the air bag. To provide a mattress with a defecation device which is improved in ease of use and operability, and which does not significantly reduce the cushioning properties of the through hole portion.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 indicates a bed mattress main body which is divided into three cushion bodies 2a v 2b t2c.

Each cushion body 2a of this pinerest main body 1. 2b,
Although not shown in detail, the spring unit 2c is constructed by polymerizing an elastic body such as urethane foam on the upper surface of a spring unit in which coil springs are connected in a flat plate shape, and covering this polymer with an exterior material.

The cushion body 2b located in the center has one end facing downward in the width direction.
An insertion section 3 opened on the side surface and a through hole 4 communicating with the insertion section 3 and opened at the center of the upper surface of the cushion body 2b are formed.

In the insertion portion 3, a second hole is provided at a position facing the through hole 4.
As shown in the figure, an air bag 7 is fixed to the bottom surface of the insertion portion 3 with an elastic band 6 made of rubber or the like.

This air bag 7 is provided with a flexible air supply pipe 8 and an exhaust pipe 9 made of synthetic resin or the like, with one end connected to the other end, and the other end of the air supply pipe 8 and the exhaust pipe 9 are connected to one end of the cushion body 2b. It is held out on the side.

A pump mechanism 10 is provided at the other end of the air supply pipe 8, and an exhaust valve mechanism 11 is provided at the other end of the exhaust pipe 9.

As shown in FIG. 3, the pump mechanism 10 includes a rod 14 having a handle 12 attached to one end and a piston 13 made of an elastic material attached to the other end.The piston 13 is slidably inserted into the air supply pipe 8. At the same time, a flange 15 is attached to the side surface of the cushion body 2b to prevent the piston 13 from being pulled out from the air supply pipe 8.

Therefore, by reciprocating the rod 14, air can be supplied to the air bag 7 and the air bag 7 can be inflated.

Further, the exhaust valve mechanism 11 provided at the other end of the exhaust pipe 9 is
As shown in FIGS. 4a and 4b, a plate body 17 having a ventilation hole 16 is held at the inner end of the exhaust pipe 9, and a valve body 19 is attached to a thread 18 formed on the inner peripheral surface of the end of the exhaust pipe 9. is screwed on.

This valve body 19 is formed with a closing surface 20 facing the vent hole 16 and a lead-out passage 21 having one end open to the outer circumferential surface of the valve body 19 and the other end opening to the end surface of the valve body 19 on the anti-occlusion surface 20 side. ing.

Therefore, if the valve body 19 is screwed in as shown in FIG. 4a to close the ventilation hole 16 with the closing surface 20, the air bag 7 will be maintained in an airtight state, and conversely, as shown in FIG. When the air bag 7 is rotated in the extraction direction to open the vent hole 16, the air in the air bag 7 is discharged from the vent hole 16 via the outlet path 21.

A set screw 22 is screwed onto the end of the exhaust pipe 9 to engage with a stepped portion 19a formed on the valve body 19 to restrict the amount of movement of the valve body 19.

Further, on the side surface of the center cushion body 2b on the side where the insertion section 3 is open, a decorative body 23 for opening and closing the opening of the insertion section 3 is detachably provided with a hook 24 or the like.

In the above-configured pinerest, when the user M takes a urinal, the air is removed from the air bag 7 and the toilet bowl 25 is inserted into the insertion portion 3 so as to face the through hole 4, as shown in FIG. If provided, the user M can relieve himself while lying down on the pinerest body 1.

In addition, after finishing using the toilet, the plate 26 is
After installing a closure body 28 having an elastic member 27 on its upper surface in the insertion section 3 so that the elastic member 27 faces the through hole 4, the pump mechanism 10 is operated to inflate the air bag 7. , the closing body 28 is pushed up by the air bag 7,
The elastic member 27 is fitted into the through hole 4 and the through hole 4 is closed.

Therefore, according to the above configuration, when the closing body 28 gets stuck and the through hole 4 is closed, it is only necessary to insert the closing body 28 into the insertion section 3 and then inflate the air bag 7, so that the operation is easy. , and the configuration therefor is relatively simple.

Furthermore, since the closure body 28 held by the air bag 7 is held elastically by the elasticity of the air bag 7, the cushioning properties of the portion of the through hole 4 into which the closure body 28 is inserted are maintained in the mattress body. There is no significant decrease compared to other parts of 1.

As described above, the present invention provides an insertion portion in the pinerest body and a through hole that communicates with the insertion portion and opens on the upper surface of the pinerest body, and also provides an air bag in the insertion portion, and allows the toilet bowl to be removed from the insertion portion. When taken out, a closing body was inserted into the through hole, and the closing body was held by inflating the air bag.

Therefore, the operation is easy because it is only necessary to inflate the air bag to hold the closing body, and no complicated mechanism is required to hold the closing body.

Furthermore, since the closing body is elastically held by the air bladder, there are many practical advantages, such as the cushioning properties of the through-hole portion of the mattress body not being significantly reduced compared to other portions.
