Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a squeezing device for clearing blockages in drainage tubes. Background Technology

[0002] Drainage tubes are medical devices used in clinical surgery to drain pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body, preventing postoperative infection and promoting wound healing. There are many types of surgical drainage tubes used clinically, some for urinary catheterization, some for wounds, and they are used in the thoracic cavity, brain cavity, gastrointestinal tract, biliary tract, etc. Surgical drainage aims to drain pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body, preventing postoperative infection and affecting wound healing. Existing drainage tubes often experience blockage problems during drainage due to intraoperative fluid accumulation, blood accumulation, solid particles, etc. Currently, in order to keep the drainage tubes unobstructed, we manually squeeze them. Some drainage tubes are viscous and difficult to drain, requiring a long time to squeeze, causing soreness in the operator's hands. Utility Model Content
