Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a negative pressure drain. Background Art
[0002] The development of modern medicine has taken rapid recovery as the future development direction. Small tissue trauma, fast disease recovery, and less patient pain are the common goals and directions pursued by the modern medical community. After the general surgery laparoscopic cholecystectomy, a negative pressure drainage tube is routinely placed in the surgical area of the gallbladder fossa. The purpose is to drain the bleeding, exudate, bile after bile leakage, and necrotic tissue in the surgical area of the body, and reduce the fever, wound pain, and inflammatory reaction caused by foreign bodies in necrotic tissue and bile after bile leakage. In actual clinical use of negative pressure drainage tubes, it is found that when bile leakage occurs after cholecystectomy, one of the treatment methods for bile leakage is to fully drain the bile, and the bile needs to be drained for a long time. Generally, it takes about one month of full bile drainage for the patient's bile leakage to gradually decrease until it disappears. The existing negative pressure drainage device has a round head during the drainage process, but sometimes the front section of the tube brought back by our patients after biliary surgery is screw-mouthed, and the two ends cannot be connected. The structure is relatively simple and the use effect is not good; therefore, we launched a negative pressure drainage device. Utility Model Content
