Water-free intestine cleaning device

Technical Field

The utility model relates to a medical appliance or a household nursing appliance, in particular to a water-free intestine cleaner.

Background

The inventor discloses a combined water-free constipation dredger earlier, need not to introduce water, can stir big hard just into little fragment, the convenient discharge, convenient to use, painful few, safe in utilization, health, simple and direct, high-efficient. But also has some drawbacks: firstly, two convex rotary cutting heads at the lower end of the sleeve are rotary cutting heads with convex sine curves, and the defects are that the convex gradient is larger, the head part of the rotary cutting head excessively protrudes to form a sharp top, so that the rotary cutting head has potential safety hazards relatively, and is not ideal enough. And secondly, the inner wall and the outer wall of the sleeve do not consider the draft angle of the die, so that the injection molding is inconvenient. And the inserted link and the sleeve adopt connecting threads, so that the inserted link is convenient to pull out after being inserted, but the threaded opening is difficult to a certain extent due to the limitation of the length of arms and the stiffness of the waist of a user, and the difficulty level varies from person to person. And fourthly, the inserted bar is a straight bar with the same diameter, the inserted bar is in clearance fit with the inner wall of the sleeve, the contact area between the inserted bar and the sleeve is large, if part machining has errors or the part is slightly deformed, the phenomenon of incapability of inserting occurs, and the requirements on part machining precision and materials are overhigh. And fifthly, the knurling arrangement can increase the friction force, but the effect of increasing the friction force is not outstanding. And sixthly, the sealing groove is arranged on the inner side of the connecting piece, so that the O-shaped ring is difficult to take off and clean, and the sealing property is poor.

The principle of water-free bowel clearing: in the embodiment, the lower end face of the sleeve is designed to be smooth and round, the top end and the bottom end of the cambered surface have height difference, when the sleeve is used, the sleeve is rotated and pushed in by hand, hard excrement is cut into the sleeve by the rotation of the cambered surface, but the hard excrement cut off by the viscosity of the hard excrement cannot smoothly enter the sleeve when the hard excrement is pushed in, and the hard excrement which is cut into the sleeve is completely pushed into the sleeve by about one third of the length of the sleeve wall, so that the cut hard excrement needs to be moved inwards by manually rotating a guide rod with a spiral part. Generally, only one-time insertion is needed during one-time defecation, but after two thirds of the length of the excrement needs to be pulled out (the excrement is not completely pulled out), the excrement needs to be repeatedly inserted for about three times back and forth, the cut hard excrement is moved into the pipe in times by rotating the spiral guide rod every time, and the sleeve is filled with the hard excrement.

The specific operation is as follows:

smearing lubricating liquid: the leaking part of the head of the inserted rod and the outer part of the sleeve are evenly coated with special human body lubricating liquid. Firstly, hard excrement is discharged into the rectum to be jacked to the anus, lubricating liquid is squeezed to the anus, and the head of the inserted rod is used for pushing the lubricating liquid into the anus to keep the inner wall of the anus lubricated.

Inserting into anus: the conical head part of the sleeve is slowly and repeatedly inserted for a plurality of times to relax the anus muscles. After the anus is loosened, the sleeve and inserted rod combination is slowly pushed in, and the sleeve and inserted rod combination is pushed in about one third of the position.

The insertion rod is pulled out and inserted into the guide rod: the plunger is pulled out of the sleeve. The guide rod is inserted into the sleeve.

Rotating defecation operation: holding the antiskid structure of the sleeve with fingers while holding the belly down and exerting force, rotating clockwise while slowly pushing inwards to push the smooth insertion part of the sleeve completely, (after one complete push, the material in the sleeve can enter 4 times of the sleeve depth, and the position of the sleeve head)

The material moves inwards: the purpose of rotating the spiral guide rod by rotating the guide rod clockwise (rotating the guide rod holding part clockwise four times by fingers) after the sleeve insertion part is pushed in completely is to move the material entering the sleeve inwards, empty the material at the head of the sleeve and facilitate the reentry of the material when the sleeve is pushed next time.

Repeating the pumping operation: the sleeve is pulled out two thirds (not all the sleeve can be pulled out) and then is rotated and pushed in again, the operation is repeated for about 4 times according to the flow, the rotating force is felt when the spiral guide rod is rotated, the sleeve is full of materials, the sleeve can be slowly pulled out from the anus, and the defecation and bowel clearing operation is completed.

Discharging the materials from the sleeve: and after the sleeve is pulled out, the spiral guide rod is rotated anticlockwise, and the materials in the sleeve are discharged.

Disabled persons:

1. patients with tumor in rectum or anus.

2. The patients with internal hemorrhoid and external hemorrhoid have lumps in the disease stage.

3. And inflammatory hematochezia in the rectum or anus.

4. Underage children and adults without the ability to conduct voluntary activities.

5. Pregnant woman, those who have not been cured by abdominal operation, cardiac-pulmonary insufficiency and severe anemia (with 1 or more items)

6. Patients with mental disease.

7. To ensure safety, please first go to the hospital to be diagnosed by the doctor without error before the contraindications can not be judged.
