Abstract

An enemator comprises a vessel for medicament, a drainage tube connected with the vessel and a duct equipped at the end of the drainage tube. The enemator is characterized in that the external surface of the duct is provided with an air bag connected with a gas filling bag by an air bag conduit, the inner cavity of the duct is also connected with an aeration ball through the gaseous tube in the aeration channel. The drainage tube and air bag conduit are provided with movably closure clips, the leaving and admission end of the aeration ball are respectively provided with check valves, and the head of the duct is a porous injector.

Description

A kind of enemator

This utility model relates to medical apparatus and instruments, particularly a kind of a kind of enemator that is applicable to that conventional colon, X-ray double-contrast barium examination are checked.

The enemator of existing clinical use is comparatively simple, coarse, and its structure is the barium agent container that hangs on certain altitude, is communicated with the conduit that inserts the human anus by drainage tube, and drainage tube is divided into two-stage nitration, and the two-stage nitration joint portion is communicated with by a hand hollow ball.During clinical use, utilize gravity principle, the barium agent flows out to conduit by container and flows into human body, and the medical care operator make barium agent medicinal liquid arrive required contrast examination position in the human body with hands extruded hollow spheroid.Its major defect is: (1) inserts the easy slippage of conduit of anus, particularly for the loose patient of anus; (2) medicinal liquid and discharged liquid can not reflux, and sealing is poor, and seepage, spillover are arranged, and cause sick bed and environmental pollution, and be unhygienic; (3) during healthcare givers's operator pressure ball, can't know from experience patient's ability to bear, often impact excessively, cause patient's discomfort.

The purpose of this utility model is to overcome above-mentioned deficiency, a kind of enemator is provided, one air bag is set on the conduit outer peripheral face, this air bag is communicated with manual gas cell by airsac tube, after conduit inserts anus, to the inflation of air bag appropriateness, reliably locate unlikely slippage by gas cell behind the airbag inflation with the human anus.In addition, also be provided with a gas tube at conduit cavity and communicate with manual inflatable ball, the patient can own operation applies suitable pressure to manual inflatable ball makes medicinal liquid arrival region of interest.

Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of enemator, comprise medicine container, drainage tube that is communicated with container and the conduit of being located at the terminal connection of drainage tube, it is characterized in that being installed with on the conduit outer peripheral face air bag, this air bag is communicated with gas cell through the air bag pipeline, and conduit cavity also is communicated with inflatable ball through gas tube by filling channel.The activity that is provided with on drainage tube and the airsac tube folder that dams, the outlet side and the inlet end of inflatable ball are respectively equipped with check valve.The planform head of conduit is the porous injector head, and the stage casing outer peripheral face is wrapped up by air bag, and afterbody has three bifurcated outlets, and conduit cavity is established three passages, and main channel front end and injector head connect, and is pegged graft with drainage tube by one of three bifurcated outlets in the rear end; The air bag passage front end that is attached on the conduit cavity wall communicates with air bag by the perforate of conduit wall, the rear end by another minute prong and airsac tube peg graft; The filling channel front opening that is attached on the conduit cavity communicates with the inner chamber main channel, is pegged graft by the 3rd branch prong and gas tube in the rear end.

Advantage of the present utility model and effect: 1. behind the airbag aeration, with conduit and anus location, unlikely slippage; 2. the patient can make medicinal liquid flow into region of interest in the body swimmingly according to self impression operation inflatable ball; 3. catheter head is for spraying head, and radiography is effective; 4. can reflux, convenient and healthy, the minimizing patient goes to toilet and gets rid of the inconvenience of barium liquid and refuse; 5. can realize medical personnel's operated from a distance inspection, raise the efficiency.

The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.

Fig. 1 is a population structure of the present utility model;

Fig. 2 is a kind of structure of this utility model conduit.

Referring to Fig. 1, medicament (barium agent) bag 2 by flexible plastic is made hangs on the drip stand by lifting hole(eyelet) 22, and the barium agent is poured into by bag mouth 23.Barium agent bag is provided with outlet opening 21 and communicates with drainage tube 5 sealed attachment, the drainage tube other end is plugged on an outlet branch of conduit and sticks (diameter is bigger), the activity that is provided with on the drainage tube 5 is dammed and is pressed from both sides 51, is the control effusive time of medicament, unclamping the folder 51 that dams during backflow.Inflatable ball 31 plugs (diameter takes second place) through another outlet bifurcated of gas tube 3 and conduit 1, the gas tube upper extremity of giving vent to anger in inflatable ball 31 and

check valve

32 and 33 are set respectively at the air inlet of inflatable ball 31, bonding is supplied gas to the conductive pipe inner chamber, can not reflux.Gas cell 41 can be made of dress Sponge in the sealed plastic bag, and outlet is communicated with airsac tube 4 on the 3rd the branch prong that is connected to conduit 1 again (diameter minimum) by joint.The folder 42 that dams is set on the airsac tube 4, and clip unclamps when air bag 12 inflations, and after air bag was heaved, the folder 42 that dams was stuck, made air bag 12 keep expanding.11 is the injector head of catheter proximal end.

Referring to Fig. 2 is a kind of enforcement structure of conduit, and conduit 1 inner chamber is made up of three parts, and the air bag channel B communicates with air bag 12 by catheter wall face 14, (being illustrated as inflated condition).Filling channel C communicates with inner chamber main channel A and injector head 11 by front aperture 15.Conduit can be used the one-shot forming of PVC plastics.This utility model enemator removes inflatable ball, and outside gas cell can repeatedly use, all the other were disposable use, meet hygienic requirements.

Claims

1, a kind of enemator, comprise medicine container, drainage tube that is communicated with container and the conduit of being located at the terminal connection of drainage tube, it is characterized in that being installed with on the conduit outer peripheral face air bag, this air bag is communicated with gas cell through the air bag pipeline, conduit cavity also is communicated with inflatable ball through gas tube by filling channel, the activity that on drainage tube and airsac tube, the is provided with folder that dams, and the outlet side and the inlet end of inflatable ball are respectively equipped with check valve.

2, enemator according to claim 1, the planform head that it is characterized in that said conduit is the porous injector head, the stage casing outer peripheral face is wrapped up by air bag, afterbody has three bifurcated outlets, conduit cavity is established three passages, main channel front end and injector head connect, and are pegged graft with drainage tube by one of three bifurcated outlets in the rear end; The air bag passage front end that is attached on the conduit cavity wall communicates with air bag by the perforate of conduit wall, the rear end by another minute prong and airsac tube peg graft; The filling channel front opening that is attached on the conduit cavity communicates with the inner chamber main channel, is pegged graft by the 3rd branch prong and gas tube in the rear end.
