Description

A speed-adjustable one-way stop-flow enema tube

technical field

The utility model relates to a medical appliance, in particular to a speed-adjustable one-way stop-flow enema tube. the

Background technique

The enema tube is an important part of the enema instrument. During the enema process, the enema liquid is slowly injected into the rectal cavity of the human body through the enema tube under the action of the micropump and fluid gravity. In order to observe the intestinal reaction of the enema recipient, the enema process is generally intermittent. , which makes the waste in the rectum very easy to reflux, causing the enema tube to be polluted. Secondly, during the enema process, the patient cannot adjust the flow rate of the enema liquid according to the individual situation. the

Contents of the invention

In order to make up for the deficiencies of the prior art, the utility model provides a speed-adjustable one-way stop-flow enema tube. the

The utility model is achieved through the following technical solutions:

A speed-adjustable one-way stop flow enema tube, including a catheter, the front end of the catheter is closed and provided with a round hole, and the upper part of the front end is provided with a one-way stop valve, which is characterized in that: the upper part of the one-way stop valve is also A double-walled conduit is provided, the outer tube of the double-walled conduit is a hard tube, the inner tube is a flexible pipe, and the inner and outer tubes of the double-walled conduit are sealed spaces, and the outer tube is provided with a seal connecting the sealed space. An airway with a balloon attached to the end of the airway.

By pressing the air bag, the patient can reduce the diameter of the inner tube of the double-walled catheter and reduce the flow rate of the enema fluid in the enema tube to adapt to the body's ability to bear it. the

The utility model solves the problems of the reflux of rectal waste and the inability of patients to conveniently adjust the flow rate of enema liquid. the

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described. the

Fig. 1 is the structural representation of the utility model. the

In the figure, 1 catheter, 2 round holes, 3 one-way stop valve, 4 double-walled catheter, 5 airway tube, 6 airbag. the

Detailed ways

Accompanying drawing is a kind of concrete embodiment of the utility model. This embodiment includes a conduit 1, the front end of the conduit 1 is closed and a round hole 2 is provided, and a one-way stop valve 3 is arranged on the upper part of the front end, and the feature is that: the upper part of the one-way stop valve 3 is also provided with a double wall Conduit 4, the outer tube of the double-walled catheter 4 is a hard tube, the inner tube is a flexible pipe, and a sealed space is formed between the inner and outer tubes of the double-walled catheter 4, and the outer tube is provided with an air guide tube that communicates with the sealed space 5. An airbag 6 is connected to the end of the airway tube 5 . the
