Description

Anus device of dosing with protective structure

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to anus device of dosing with protective structure.

Background

Anorectal administration is one of the treatment means for various anorectal diseases, and comprises two types of liquid medicines and solid medicines.

When carrying out liquid class medicine and dosing, generally adopt the syringe propelling movement to in the rectum, but because traditional syringe exists that the distance of going out the medicine is short, pressure is unstable, too big easy blowout forms mixed aerosol, the undersize easily flows from the anus, the medicine does not reach in the rectum, can not exert good curative effect, the general volume of traditional syringe is certain simultaneously, when carrying out the bulk dose and dosing or multiple medicine and dosing, need extract the anus with the syringe and inhale the liquid medicine, reciprocal pulling out and inserting the syringe, can cause certain stimulation to the rectum, medical personnel's work load has also been increased simultaneously.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an anus device of dosing with protective structure aims at solving current syringe and when administering to the anus, because traditional syringe exists out the medicine distance short, and pressure is unstable, and too big easy blowout forms mixed aerosol, and the undersize easily flows from anus, and in the medicine did not reach the rectum, can not exert the problem of good curative effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an anus device of dosing with protective structure, includes empty section of thick bamboo, the inside cover of empty section of thick bamboo is equipped with the piston axle, the one end of piston axle can be dismantled and is connected with the piston, the outer wall of piston and the inner wall sliding connection of empty section of thick bamboo, just two spacing bayonet sockets have still been seted up to one side of piston symmetry, the one end of empty section of thick bamboo is inside to be fixed to be equipped with the spacing fixture block relative and size looks adaptation with spacing bayonet socket position, the other end nipple of empty section of thick bamboo has cup jointed the pipe of dosing, the one end outer wall of dosing pipe has seted up a plurality of exports of dosing, the outside of empty section of thick bamboo still overlaps and is equipped with the splashproof mantle.

In order to make convenient adding of liquid medicine to empty section of thick bamboo inside, as the utility model relates to an optimal scheme: the middle part of the piston is provided with a through threaded hole, and the threaded hole is in threaded connection with a threaded connector fixedly arranged at one end of the piston shaft.

In order to make and prevent to cause a large amount of pollutions after the direct blowout of aerosol material, conduct the utility model relates to an optimal scheme: the splashproof mantle is loudspeaker form, just the fixed rubber circle that is equipped with of one end that the empty section of thick bamboo was kept away from to the splashproof mantle, the end department of the other end of dosing pipe other end is located to the fixed cover of the other end of splashproof mantle.

In order to reduce the stimulation to the rectum after the administration tube is inserted into the anus, the utility model is a preferred proposal: one end of the administration tube is fixedly provided with a sealing plug, and the sealing plug is matched with the diameter of the administration tube and is arc-shaped.

In order to make the medical staff intuitively observe the dosage, the utility model relates to a preferred scheme: and scale marks are printed on the outer part of the hollow cylinder.

Compared with the prior art, the beneficial effects of the utility model are that:

1) the piston shaft of the administration device can not pull out the piston through the arranged limiting clamping block, so that the phenomenon that the medicine and the piston shaft thereof pop out due to overlarge internal pressure of the hollow cylinder in the administration process is effectively prevented, the administration outlet is arranged at the outer side of the administration tube, the irritation can be reduced in the administration process, the administration tube can be inserted into the rectum more deeply, the focus is better reached, the medicine effect is ensured, and meanwhile, the medicine liquid can be effectively prevented from flowing back to the hollow cylinder;

2) in the process of inserting the administration tube into the anus, the external splash-proof overcoat membrane can be folded towards one end of the hollow cylinder through the blockage of the buttocks of a patient to form an umbrella-shaped protection structure, so that a large amount of pollution caused by directly spraying aerosol substances is prevented;

3) because the piston shaft passes through screwed joint and piston threaded connection for the piston shaft can carry out quick assembly disassembly with the piston, when advancing high dose or multiple medicine and dosing, the screw thread trompil of accessible piston is direct to the inside interpolation of empty section of thick bamboo, need not to extract the administration pipe, reduces the stimulation to patient's rectum simultaneously, has also reduced medical personnel's work load, makes the anus device of dosing have better practicality.
