[0008]
In this embodiment, as shown in FIG. 2, the discharge tube 8 is connected to the discharge port 1a, the protection body 6 is closed, the water-soluble cap 7 is put on, and the insertion is performed from the anus 12. After the insertion, when air is injected from the air injection tube 10a with a check valve, the two balloons 10 are inflated and fixed to the anus 12 in a watertight manner. If necessary, hot water is injected from the discharge tube 8 to forcibly dissolve the cap 7.
After that, the drive unit 5 is fitted to the rear part of the piston body 4 at the base end of the cylinder 1. At this time, the locking pin 5f of the fitting cylinder part 5d of the driving part 5 is inserted into the L-shaped locking slit 4d of the piston body 4 and is rotated at the back to drive the piston body 4 via the locking pin 5f. Part 5 can be moved back and forth together. At the same time, the linking portion 2b at the shaft end of the center rotary shaft 2a is fitted to the coupling portion 5c at the tip of the drive shaft 5b and connected so as to rotate together in the rotation direction.
[0009]
Thereafter, by pushing the drive unit 5, the piston body 4, the rotating shaft 2a, the rotating blades 2, the ring 3d at the tip, and the stool crushing blade 3 are pushed toward the back of the rectum 13.
When the ring 3d protrudes forward from the cylindrical body opening 1c, it comes into contact with the inner projection 6c of the aggregate 6a, and the aggregate 6a is outwardly inclined so as to spread outward around the connecting portion 6d at the base end thereof, and is folded. The protective film 6b is stretched in a trumpet shape to form the protective body 6. When the electric motor 5a of the drive unit 5 is operated in this state, the rotation shaft 2a rotates via the drive shaft 5b and the coupling unit 5c. As a result, the stool crushing blade 3 at the tip is rotated, the stool at the center portion is crushed by the blade body 3a, and the rotating blade 3b is rotated outward around the pivot 3c by centrifugal force due to the rotation, and is stopped by the stopper 3e. The open state is retained by being locked, and the stool is crushed over a wide area by the rotary blade 3a. Since the stool crushing blade 3 is in the protective body 6, there is no direct contact with the intestinal wall, and the intestinal wall is not damaged. The stool crushed by the blade 3a and the rotary blade 3a enters the cylinder through the distal end opening 1c of the cylinder 1 by the suction force of the suction pump 9, and the stool is moved in the proximal direction by the rotating blade 2 of the internal screw blade. It is forcibly fed, crushed reliably by the crushing blades 3d, and discharged to the outside by the discharge tube 8 through the discharge port 1a. As described above, in the present embodiment, the drive unit 5 is detachably attached to the cylindrical body 1, so that the drive unit 5 is less liable to be stained by a stool, especially by interposing the piston body 4, and is replaced or disposable. The cylinder 1 can be used many times.
Further, the stool in the cylindrical body 4 can be forcibly moved toward the discharge port 1a by the rotating blades 2 in the cylindrical body. Less clogging.
[0010]
【The invention's effect】
As described above, according to the present invention, in addition to the negative pressure suction by the pump, the stool inside the cylinder is forcedly fed by the rotating blades in addition to the negative pressure suction, and the stool is surely fed, and the suction from the opening at the tip of the cylinder. It also increases power and enhances defecation capacity.
If the drive unit is detachable from the cylinder, a drive unit with less contamination can be used many times for a cylinder that cannot be used unless it is washed or a disposable cylinder, and the cost of the defecation device can be reduced.
Further, if a crushing blade is provided in the middle or at the base end of the rotating blade, the crushing blade can be reliably reduced in size and can be sent without clogging the discharge tube.
