Description

Flushing drainage catheter

Technical Field

The utility model relates to the technology of medical instruments, in particular to a flushing drainage catheter.

Background

Many drainage catheters are commonly used to insert into the chest or abdomen of a person to draw excess or harmful fluid from the interior. Current drainage catheters are generally flexible enough to bypass organs or tissues in the body to reach the site of the fluid accumulation for aspiration. However, flexible drainage catheters do not penetrate into the mass of hardened material accumulated in the body, nor do they provide a means for localized loosening of hardened, firmly-packed foreign bodies. In order to conveniently suck the effusion, the suction port is usually arranged at the foremost end of the drainage catheter, and the opening at the front end easily causes secondary damage to human tissues and organs.

At present, the population of China tends to be aged, and more elderly people do not have special loosening and lubricating tools for defecation difficulty due to dry excrement, and the people often need to discharge the excrement by hands or with the help of tools. Foreign body management of uterine lesions in gynaecology also requires administration of irrigation and drainage to the uterus in order to accelerate healing. At present, no professional irrigation drainage catheter aiming at anus irrigation and drainage, uterus irrigation and drainage and vagina irrigation and drainage exists, and the patient cannot be well treated with the treatment process.

In recent years, colorectal cancer has become a high-grade malignancy worldwide. A large number of patients receive resection anastomosis of middle and low rectum every year, postoperative anastomotic leakage is a difficult problem troubling surgeons, and whether one operation patient has anastomotic leakage or not cannot be accurately judged in advance. Feces often remain in the rectal cavity to cause infection and influence the healing of the anastomotic stoma, which is an important reason for anastomotic leakage. The leakage of anastomotic stoma can cause the problems of delayed healing, anal stenosis, anal function loss and the like. The severe patients can cause diffuse peritonitis, which endangers the life of the patients. It is often necessary to re-surgically divert stool.

There are two common techniques for preventing anastomotic leakage: one is to perform preventive proximal enterostomy and perform another operation after the rectum anastomosis is completely healed; the other is to place a rubber tube through anus for pressure reduction and drainage. These methods all add much pain to the patient and are unacceptable.
