Balloon expansion type anti-falling rectum catheter

Abstract

The invention provides a balloon expansion type anti-falling rectum catheter. The balloon expansion type anti-falling rectum catheter comprises a dosing tube module, a catheter body module, an extension tube module and a sealing structure module, wherein the dosing tube module comprises a dosing tube, an outer conical connector and a dosing tube cap, and an infusion hole is formed in the portion, close to the tube cap, of the front end of the dosing tube; the extension tube module comprises an extension pipeline and a conical joint in the pipeline; the dosing tube penetrates to the front end of a front catheter along a side hole of the three-way joint of the catheter; a dosing tube clamp and a tube clamp connecting plug are sleeved in the side hole of the three-way joint of the catheter; and deformation is adjusted by rotating a three-way joint anti-drop nut. The balloon expansion type anti-falling rectum catheter is simple and reliable in structure, smooth in dosing tube pushing and convenient to operate, three modes of intestinal irrigation, dosing and enema can be completed by one-time rectum catheter insertion, and the catheter can be effectively prevented from falling off in a treatment process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a balloon-expandable prolapse-preventing rectal catheter. [0002] technical background [0003] Rectal administration refers to sending drugs into the intestine through the anus. The rectum is closely connected with the anus, and the rectum opens to the anus. It enters the large circulation through the rapid absorption of the rectal mucosa, so that the drug can exert its effect locally or throughout the body to treat systemic or local diseases. A method of drug delivery. There are three main methods of rectal administration: retention enema, rectal drip, and suppository insertion. Among them, a rectal catheter is often required for rectal administration. [0004] At present, the rectal catheter body in the market is relatively thick and hard, with high friction, and the overall comfort of the patient is poor; secondly, the connection between the rectal catheter infusion...

AI Technical Summary

Problems solved by technology

[0004] At present, the rectal catheter body in the market is relatively thick and hard, with high friction, and the overall comfort of the patient is poor; secondly, the connection between the rectal catheter infusion tube and the catheter body is not sealed, and the liquid medicine overflows from the connection port during use. The drug administration environment is not hygienic and safe; in addition, at present, rectal catheters are generally prevented from falling off by airbags, and many hospitals do not have corresponding air compressors.
