Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a wound negative pressure exudate collection structure. Background Art

[0002] During surgery, a drainage tube needs to be placed because there is blood accumulation, fluid accumulation or pus in the wound to drain the blood and fluid out of the body. Sometimes two drainage tubes need to be placed for drainage at the same time, or one tube is used for flushing and the other for drainage. Keeping the drainage tube unobstructed is one of the important measures to ensure the effect of surgery and reduce postoperative complications. At present, it is usually used to place a drainage tube by making a small incision next to the wound, suture and fix the drainage tube, and connect a negative pressure ball or drainage bag for drainage. The commonly used drainage methods now have the following shortcomings: 1. Placing the drainage tube is cumbersome and requires multiple suturing operations. 2. The negative pressure ball uses manual extrusion to obtain negative pressure. When squeezing, the plug at one end needs to be opened. The blood in the negative pressure ball is easy to contaminate medical staff, and external bacteria are also easy to enter the body along the negative pressure ball to cause wound infection. 3. When pus is drained, there is a pus mass flowing out, and the interface is easy to block. Utility Model Content
