Drawings

Fig. 1 is a sectional view of the present invention.

In the figure: 1. a conduit; 2. a support portion; 3. a nozzle; 4. an anal canal; 5. a medicine inlet; 6. capping; 7. a one-way valve; 8. one-way air inlet rubber saccule.

Detailed Description

Referring to the attached drawing, an anal canal device of dosing, including pipe 1, supporting part 2, nozzle 3, anal canal 4, advance medicine mouth 5, block 6, check valve 7 and one-way rubber sacculus 8 that admits air, 1 end of pipe has one-way rubber sacculus 8 that admits air through check valve 7 intercommunication, 1 middle part of pipe enters medicine mouth 5, it has block 6 to enter 5 outer wall threaded connection of medicine mouth, 1 head end outer wall of pipe is equipped with outside convex supporting part 2, 2 head ends of supporting part are equipped with nozzle 3, 3 inlet of nozzle communicates with pipe 1.

More specifically, the supporting portion 2 is an ellipsoid having a hollow structure inside.

More specifically, the nozzle 3 has a hemispherical structure.

The utility model discloses a theory of operation and use:

the method comprises the following steps: when in use, the cap 6 is unscrewed at first, liquid medicine is input into the medicine inlet 5 through the syringe and then stored in the catheter 1, and the cap 6 is connected to the outer wall of the medicine inlet 5 through threads;

step two: coating certain lubricating oil on the outer walls of the nozzle 3 and the support part 2, and plugging the nozzle 3 and the support part 2 into the anal canal 4 through the anus of a patient, namely, at a position which is 2cm to 4cm away from the anus;

step three: medical personnel extrude one-way rubber ball bag 8 that admits air, one-way inside gas that admits air rubber ball bag 8 passes through check valve 7 and gets into inside pipe 1, pipe 1 internal pressure increases, and then make the inside liquid medicine of pipe 1 spout to the inner wall of anal canal 4 through nozzle 3, through slowly extrude one-way rubber ball bag 8 that admits air many times, all liquid medicines are all spouted in pipe 1, although at follow-up spraying in-process can spray some gas by the way, this gas can be discharged with the form of flatus at follow-up in-process, can not cause the injury to patient's health.

The supporting part 2 is an ellipsoid with a hollow structure inside;

the first function is to support the muscle of the anal tube 4 to keep a certain distance between the inner wall of the anal tube 4 and the nozzle 3, which is convenient for the liquid medicine to be sprayed on the inner wall of the anal tube 4;

the second hollow structure has the functions of reducing the whole weight, facilitating the operation of medical personnel and reducing the cost;

the third function is that the ellipsoid is convenient for being placed in the anus, thereby relieving the pain of the patient in the medicine feeding process and being convenient for the operation of medical care personnel.
