Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a replaceable disposable collection bag for negative pressure drainage balls. Background Technology

[0002] A negative pressure drainage ball is a drainage device used in clinical medicine. It uses internal negative pressure to create suction, drawing exudate, blood, and other fluids from the body's tissues into the drainage ball. When the drainage ball is compressed, the internal air is expelled, creating a negative pressure environment. Under the influence of this pressure difference, fluid is continuously drawn into the drainage ball.

[0003] In existing technologies, the fluid drained by a negative pressure drainage ball needs to be collected in a disposable collection bag. However, replacing these disposable collection bags is inconvenient, and in some cases, medical staff need to pour the blood from the drainage ball one by one into a measuring cup, which increases the workload of medical staff and thus affects the drainage efficiency of the negative pressure drainage ball.
