Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for forcibly discharging stool inserted from the anus and not excreted in the intestine by forcibly crushing, dividing, stirring, and scraping (hereinafter simply referred to as crushing). This device is especially useful for bedridden elderly people, patients, and those without self-defecation.
[0002]
[Prior art]
In the past, stools that stayed in the intestine due to stool and were unable to defecate were scraped by a doctor / nurse by inserting a finger through the anus. This was time consuming.
The inventor has developed an apparatus for solving this problem. This developed a defecation device in which a petal-like protective body for protecting the intestinal wall was expandable and contractible at the tip of a cylindrical body inserted from the anus, and a crushed body for crushing the stool was rotated inside. The stool in the intestine is crushed by the crushed body, and the stool is forcibly discharged by suction with a suction device connected to the cylinder.
However, since the connecting portion of the hard plate and the cylindrical body of the protective body of this device is relatively weak, there is a high risk that it will come off the cylindrical body when receiving a force from the side or a twisting force.
[0003]

Further, the protective film 3d is provided so as to be folded back at the tip of the hard plate 3a to the inside of the hard plate 3a having a predetermined length so as to protect the tip of the hard plate 3a from being damaged by the human body.
[0009]
Next, a slide cylinder 4 having a size capable of sliding inside the cylinder 2 is provided. The slide cylinder 4 is provided with a bearing 4a at the tip. This tip portion is opened at a portion other than the bearing 4a so that the inside of the slide tube 4 and the tip portion can communicate with each other. Next, a long hole-like opening 4b that is long in the front and rear direction is provided in the outer peripheral portion of the slide cylinder 4. Next, two places facing the rear end of the slide cylinder 4 and a lever 4c extending in the outer diameter direction are provided. Further, the base end portion of the lever 4 c is provided with a thin portion that engages with the slit 2 a of the cylindrical body 2. Further, a small protrusion 4d that can be engaged with the engagement hole 2c of the cylindrical body 2 is provided on the front portion of the lever 4c. Next, grooves 4 e are provided at eight locations on the outer peripheral portion of the tip of the slide cylinder 4.
Next, a motor 5 is provided at the rear end portion of the slide cylinder 4. A partition is provided in front of the motor 5 mounting portion and the front thereof, and only the motor output shaft projects from the partition into the slide cylinder 4. Next, the long rotating shaft 7 is attached to the bearing 4a so as to be rotatable, and the rear end of the rotating shaft 7 and the output shaft of the motor 5 are connected by the coupling 8 so as to be coaxially connected. Next, the crushed body 6 is attached to the rotating shaft 7 protruding from the tip of the slide cylinder 4, and the crushed body 6 is rotated by driving the motor.
Next, two annular balloons 10 that are close to the tip of the cylindrical body and that can be expanded and contracted by air are provided, the tube 11 is attached to the connecting portion 2 d of the cylindrical body, and the switch 12 is attached to the other end of the tube 11. Next, a pressure-feed pump 15 that sends hot water from the hot water container 13 is connected to one of the switching destinations of the switch 12, and a suction pump 16 that sucks into the other switching destination and accommodates in the excretory container 14 is connected.
[0010]
In order to use the defecation device 1 of the present embodiment, first, the slide cylinder 4 is inserted into the cylinder body. At this time, as shown in FIG. 4A, the small protrusion 4d of the lever 4c is engaged with the engagement hole 2c of the flange 2b so that the lever 4c of the rear end portion of the slide cylinder 4 contacts the flange 2b of the cylinder 2. As shown in FIG. 2, the slide cylinder 4 is prevented from malfunctioning by preventing the slide cylinder 4 from being inserted further toward the front of the cylinder 2, and then the protector 3 is contracted as shown in FIG. 2. A water-soluble cover 9 is attached to the protector 3. It inserts into the rectum from the anus of the person who performs the treatment in this state. At this time, since the slide cylinder 4 is prevented from moving forward with respect to the cylinder 2, it can be inserted safely. When inserted in this manner, the cover 9 is soluble in water and therefore dissolves in the intestines. In addition, the balloon 10 is inflated after insertion to fix the cylindrical body 2 to the human body and prevent the intestinal matter from flowing down. Next, as shown in FIG. 4B, the slide cylinder 4 is rotated about 90 ° with respect to the cylinder 2, and the slit 2 a of the cylinder 2 is engaged with the narrowed portion of the base end of the lever 4 c of the slide cylinder 4 Then, the lever 4c is pushed forward to move the slide cylinder 4 forward. If the tip of the slide cylinder 4 reaches the engagement protrusion 3b of the base end portion of the hard plate 3a of the protector 3, the grooves 4e provided at the eight positions on the tip of the slide cylinder 4 are respectively engagement protrusions of the hard plate 3a. Engage with 3b. Since the lever 4c and the slit 2a are engaged to determine the rotation positions of the cylinder 2 and the slide cylinder 4, the rotation position is not shifted and the engagement protrusion 3b and the groove 4e are not engaged. When the slide cylinder 4 is further pushed forward, the bottom surface of the groove 4e pushes the engagement protrusion 3b, whereby the hard plate 3a rotates outward from the connection portion with the cylinder 2 as a base point. Therefore, the protection body 3 moves in a petal shape. At this time, the engagement protrusion 3b engages with the groove 4e, so that the side surface of the engagement protrusion 3b has a predetermined gap with the side wall of the groove 4e, and a lateral force is applied to the hard plate 3a. When applied, the hard plate 3a is supported such that the side surface of the engaging projection 3b and the side surface of the groove 4e are in contact with each other, and the side wall of the groove 4e receives a force. Therefore, the connecting portion between the hard plate 3a and the cylinder 2 is damaged, and the hard plate 3a is prevented from being detached from the cylinder 2 so that it can be used more safely.
[0011]
When the protective body 3 is expanded in this way, the switch 12 is changed to the pressure pump 15 side, the pressure pump 15 is operated to supply hot water into the intestine, and the switch 12 is changed to the suction pump 16 side. Further, the motor 5 is driven to rotate the crushed body 6 so that the intestinal matter is crushed and divided by the crushed body 6. When the intestinal matter is crushed and divided in this way, the suction pump 16 is operated so that the crushed and divided intestinal matter passes through the opening 4b and the connecting portion 2d from the inside of the slide cylinder 4 together with hot water. And suck into the excretory container. By performing the treatment in this way, the treatment can be performed cleanly. Further, when the intestinal matter is pushed by the crushed body 6 and moves or rotates together, since the locking claw 3c is provided inside the hard plate 3a, the hard plate 3a is slightly contracted. If it is made to crush and divide by pressing with the latching claw 3c, crushing and dividing can be performed efficiently and reliably.
When the treatment is completed in this manner, the balloon 10 is contracted so as to remove air, and the slide cylinder 4 is moved rearward so that the lever 4c is pulled out in a state of being applied to the collar portion 2b. The plate 3a is removed in a contracted state due to resistance in the intestine.
[0012]
【The invention's effect】
According to the present invention, the side of the base end portion of the hard plate is restrained and reinforced, and the defecation device can be used more safely.
In the case where a locking claw for stopping the movement of the intestinal object is provided inside the hard plate, the intestinal object can be reliably and efficiently crushed and divided so that the treatment time can be shortened and surely treated.
A defecation device that is provided with a crushed body that is rotated by an electric motor and that restricts the range of movement of the slide cylinder with a slit and a lever can be used more safely.
