Description

Detachable Multifunctional Abdominal Drainage Tube

technical field

The invention relates to the field of medical technology, in particular to a removable multifunctional abdominal cavity drainage tube.

Background technique

Drainage tubes should be placed routinely after surgical abdominal and pelvic surgery to guide pus, blood, urine, exudate and other fluids accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing. At present, the single-lumen drainage tube is the most widely used in clinical practice. The blockage of the drainage tube has become a common situation after surgery, especially for those with a lot of postoperative bleeding or drainage. The skin interface leaks out, making the incision dressing and clothes soaked, which not only causes discomfort to the patient, but is more prone to infection and poor incision healing. It affects postoperative recovery, increases the cost of patients, and in more severe cases can endanger the patient's life. Therefore, how to prevent drainage tube blockage has become a hot research topic for clinicians. In view of the above problems, we have invented a removable multifunctional abdominal drainage tube, which is simple in structure, cheap, convenient and practical, and also has functions such as anti-blocking, negative pressure suction, and intracavitary injection.
