Description

This device is a defecation assisting device used mainly for defecation care for the elderly and disabled who cannot discharge the accumulated stool by themselves in welfare medical care, and especially waters stubbornly solidified feces due to loss of water. The present invention relates to a defecation dissolving device suitable for dismantling by.

Waste sent from the small intestine to the large intestine reaches the rectum via the ascending colon, transverse colon, and descending colon due to peristaltic movement, and stays as feces near the anus, sometimes exerting abdominal pressure and at the same time. The feces are discharged by passing through the anus while loosening the sphincter muscle. However, in the elderly and the handicapped, the intestinal movement of defecation is slow and the residence time is long, so that much water is lost. Therefore, feces often stay as stubborn solids in the rectum.

In this case, it is impossible to defecate on its own, so the nurse put on gloves and inserted his finger into the anus and pulled out the feces with his finger, but this is the most disliked job in nursing care. Due to the fact that there is only one, the applicant has previously proposed a defecation dissolving device capable of removing feces (Patent Document 1).

The defecation dissolving device mainly consists of a tubular stalk that is inserted into the anus so that liquid (water) can be injected into the anus and dismantled waste can be sucked, and after the tip of the stalk is inserted into the anus. An opening and expanding portion that can be expanded like a trumpet mouth so as to receive the feces in a wide mouth is provided, and a large number of nozzles are scattered on the inner surface (upper surface) facing the feces in the expanding portion.

As a rear cover of the handle, a water supply device that sends compressed water to this by a pump and a disposal device that sucks and separates the waste of the excrement feces are attached, so while activating the water supply device, When liquid or water is ejected from the nozzle at once, the fountain flow dissolves hard feces, and when the dissolved water is discharged to the end through the inside of the stalk tube, it is separated by a centrifuge or the like. It is classified into the state of being discarded.

Japanese Unexamined Patent Publication No. 7-88176

In the conventional one, polyethylene or polypropylene is selected as the soft plastic material for the molding material so that the dilation part that opens in the anus gently touches the intestinal membrane, but the delicate intestinal wall is still damaged by the trumpet-shaped brim-shaped edge. There is a risk, and the liquid touches the intestinal wall along the trumpet-like spread, which legally regulates contact with water as it has a negative effect on physical condition even if it is simply water. Partly because of this, it was difficult to put it to practical use.

In view of the above circumstances, this device does not touch the inner wall of the rectum at the front part to be inserted into the anus, and even if it is touched, it does not hurt because it touches gently, and even if it is a stubborn defecation. An object of the present invention is to provide a safe defecation dissolving device that can be easily solved by water pressure and that the injected water solution does not come into direct contact with the inner wall of the rectum.

In view of the above circumstances, this device provides a defecation aid that precedes the defecation and suction, a water supply device that pumps a liquid such as water to the defecation aid, and a suction force to the defecation aid. It consists of a pneumatic suction device, and the defecation aid has a soft plastic tubular mouth connected to the tip of the suction waste pipe in the direction of the pneumatic suction device, and the tubular mouth has a rounded tip edge. By providing a water passage hole in the peripheral wall for passing water from the water supply device, a plurality of nozzles are radially arranged on the inner peripheral surface of the mouth portion horizontally or in an inclined direction toward the center of the cylinder. Provided is a defecation dissolving device characterized by the above.

Since the defecation dissolving device is configured as described above, for use, when the tubular mouth at the tip of the defecation aid is inserted into the anus and the water supply device, pneumatic suction device, etc. are activated, the tubular mouth becomes the anus. Since the suction force can be strongly exerted in the rectum by fitting it completely, the defecation can be sucked into the tubular mouth and brought close to it. And, in the situation of approaching the feces, the fountain from the nozzle spouts from the tubular mouth, so it rarely hits the intestinal wall, and it hits the feces strongly radially, so even if it is a stubborn feces. It is unraveled, and the unraveled hydrolyzate is sucked into the tubular mouth and collected in the direction of the pneumatic suction device through the waste pipe.

As described above, according to the defecation dissolving device of the present invention, since the tubular mouth fits tightly into the anus and the feces are brought closer by suction force, it is not necessary to insert it deeply, and the head portion to be inserted into the anus is a cylinder. Even if it touches the inner wall of the rectum because it is the rounded surface at the tip of the mold mouth, there is no risk of damaging it, and the stubborn feces can be easily dissolved by water pressure due to the jets from the radially arranged nozzles. At this time, since the radial fountain is drawn into the tubular mouth, it does not overflow and there is no risk of directly touching the inner wall of the rectum, which has an excellent effect of being safe.

It is explanatory drawing which shows the defecation dissolution apparatus of this invention as a whole. It is sectional drawing which shows the use state of the defecation dissolution apparatus in the aspect which the feces are solved. It is a partially enlarged sectional view of the tubular mouth in the defecation dissolution device. It is explanatory drawing which shows the other aspect which the feces are solved together with other Examples. It is explanatory drawing which shows the still other embodiment in which feces are solved together with still other examples.

In this invention, the arrangement, orientation, and the like of the nozzles 12 arranged radially are various and are not particularly limited (claim 1), but the following findings have been obtained from various experiments and studies.

The angle of the nozzle 12 with respect to the horizontal is determined by the insertion depth of the tubular mouth 11, but as a general example, it is preferably about 30 degrees, and four locations are optimal. In the experiment, when the gear pump was used, the water pressure on the water supply side was 3.5 and the water pressure on the suction side was 2.0. In addition, the internal pressure and the amount of water are adjusted with a pressure sensor.

Further, the number of nozzles 12 is determined by the insertion depth, although it depends on the age of the patient and the like. As a general example, in the case of a depth of 1 cm, it seems that about 4 pieces are sufficient. Reference numeral 8 is a sphincter muscle that tightens the anus. In addition, there are hubstras, diverticula, etc. throughout the intestine.

1 to 3 show an embodiment, in which the defecation dissolving device P sucks the defecation assisting device 1, the water supply device 3 for pumping water to the defecation assisting device 1, and the defecation assisting tool 1 with a suction fan. It comprises a pneumatic suction device 5 that exerts a force.

The defecation assisting tool 1 is mainly composed of a waste pipe 7 in which the suction force of the suction fan 27 of the pneumatic suction device 5 works via the suction hose 6, and the tubular mouth 11 can be replaced therewith. It is connected to the tip. When this is inserted into the anus, the tubular mouth 11 fits in the anus and suction force is applied to the feces 9 from the tip opening. Then, each nozzle 12 that ejects water is arranged inside near the tip opening in the tubular mouth 11 so that water can be concentrated and ejected to the feces 9 that are as close as possible. (Hereinafter, for convenience of explanation, the entire nozzle arranged radially is simply abbreviated as a nozzle).

From the viewpoint of safety, the tubular mouth 11 is formed of a soft plastic such as polyethylene or polypropylene into a short tubular shape, and a rounded surface 13 is formed on the outer peripheral edge of the tip. Further, an annular convex surface 15 is formed on the inner peripheral surface near the tip so as to project low over the entire circumference, and a waste pipe 7 is connected to the base end.

If the nozzle is inclined to open on a flat surface, it becomes an elliptical opening in which the fountain force is easily dispersed. However, in the case of the figure, the nozzle opening (tangent line) inclined upward on the arc-inclined surface above the rounded surface 13. Since the aperture direction of the nozzle is perpendicular to or close to a right angle to L), the opening is a perfect circle or an ellipse close to a perfect circle. In the case of the illustration, since the nozzle 12 is shown in an inclined direction close to a right angle to the tangent line L, the nozzle opening shape is not a perfect circle but a slightly elliptical shape, but it is not intended to exclude the perfect circular opening shape.

The waste pipe 7 is connected to the water passage hole 19 of the tubular port 11, and is provided with a connection portion 23 with the water supply hose 21 of the water supply device 3 (note that the connection portion 23 is an example of a display example. Yes, in this case it is represented by an outline of the waterway). The water supply device 3 includes a pump for water supply and a water storage tank 24. Further, the pneumatic suction device 5 is provided with a suction fan 27, a centrifuge that separates the sucked waste from water, and a waste tank 26. Since these are ancillary matters, they are not shown.

The tubular mouth 11 is thickly formed of a soft plastic such as polypropylene or polyethylene, and a water passage hole 19 is formed in each nozzle 12 within the wall thickness, and the water passage hole 19 is opened in the annular convex surface 15. Regarding the method of providing the water passage holes 19, the tubular mouth 11 is soft, but each water passage hole 19 is formed by inserting a thin tube 12a also made of soft plastic, and the softness is maintained as a whole. It should be noted that the method of providing the water passage hole 19 may be another method.

Regarding use, when the tubular mouth 11 is inserted into the anus (FIG. 1) and the water supply device 3 and the pneumatic suction device 5 are operated, suction force is applied to the opening of the tubular mouth 11 as shown in (FIG. 2). At the same time as the nozzle 12 opens radially and the fountain is ejected into the feces 9, the mixed water with water is sucked into the waste pipe in order to solve the problem. It is collected by the pneumatic suction device 5 through the suction hose 7 and the suction hose 6.

The modes of disassembly and suction / discharge of feces 9 are shown below together with the figure.
(1) In the case of FIG. 2, large feces 9 face each other at the tubular mouth 11, and fountains from nozzles 12 arranged radially toward the center thereof are concentrated to form a scraped portion 30. Eventually, it collapses as a whole and is sucked into the pneumatic suction device 5 from the tubular mouth 11 (see arrow Q). Water rarely touches the rectal wall. In the pneumatic suction device 5, water and feces are separated and treated as described above.
(2) In the case of FIG. 4 When the feces 9 is relatively small, it is sucked into the tubular mouth 11 and stopped by hanging on the annular convex surface 15, and in this state, it is finely divided by receiving the hydraulic force from the nozzle 12. It is broken down, escapes from the diameter of the annular convex surface 15, and is sucked by the pneumatic suction device 5. Therefore, it is possible to prevent the small dung 9 from being clogged in the exhaust pipe 7 and the suction hose 6.
(3) In the case of FIG. 5, a plurality of nozzles 12 are projected so as to gather, and in this case, a water bundle 33 having a momentum extending in a bundle shape is formed on the front side, so that a distant dung can be targeted.
