Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a disposable suction bag that is easy to seal and convenient to operate. Background Technology

[0002] Disposable suction bags are sterilized plastic bags used to collect liquids and are a common auxiliary hygiene material in clinical practice. A utility model patent with Chinese patent publication number CN208958887U discloses a disposable medical suction bag. This medical suction bag generates internal suction by squeezing the elasticity of an air bladder. Membrane valves are installed at the ends of the suction tube and the guide tube of the air bladder. Squeezing the air bladder draws liquid into the air bladder and into the suction bag through the opening and closing of the membrane valves. When squeezing the air bladder stops, the membrane valve of the guide tube automatically closes, preventing backflow of liquid into the suction bag. This device has a simple overall structure, is easy to operate, and has a low cost, while also overcoming the drawback of backflow of liquid in existing suction bags. Research on existing technologies revealed that the operation of existing devices is also inconvenient. Therefore, this utility model proposes an easily sealable and convenient disposable suction bag. Utility Model Content
