Detachable multifunctional abdominal cavity drainage tube

Abstract

The invention discloses a detachable multifunctional abdominal cavity drainage tube, wherein an outer catheter and an inner catheter of the drainage tube are soft plastic tubes, and the outer catheterand the inner catheter are matched and connected with an outer connection structure through an inner connection structure; when the patient is drained, the outer catheter and the inner catheter playa supporting role in combination, so as to avoid a situation that drainage cannot be performed due to squeezing the inner catheter. When the drainage catheter is blocked, the inner catheter can be removed from the outer catheter to avoid secondary puncture and alleviate the pain and burden of patients. The sealing plug of the water injection pipe on the external catheter can be connected with thesyringe after being removed, and can be used for endoluminal drug infusion treatment or irrigation. If negative pressure suction is required for the infected wound, the drainage bag valve can be turned off and the negative pressure extraction device is connected to the negative pressure tube of the inner catheter for negative pressure drainage. The drainage tube has the functions of blockage prevention, negative pressure suction, intracavity drug filling, etc., is convenient and reliable to implement, and has good market application value.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a detachable multifunctional abdominal drainage tube. Background technique [0002] Drainage tubes are routinely placed after abdominal and pelvic surgery to guide pus, blood, urine, exudate and other fluids accumulated between human tissues or 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 clinically. The blockage of the drainage tube has become a common situation after surgery, especially in patients with postoperative bleeding or drainage fluid. The outflow from the skin interface makes the incision dressing and clothes soaked, which not only causes discomfort to the patient, but also makes the patient more prone to infection and poor incision healing. Affect postoperative rehabilitation, increase patient's cost burden, and more serious cases may endanger...
