Bladder evacuator

摘要

A method of irrigation of a cavity of a human body by means of a medical device consisting of a container for a fluid and a filter. The container is formed with an open neck and a peripheral wall defining the receiving volume. A portion of the peripheral wall at the open neck is squeezable. The filter consists of an elongated filter element situated at an open neck of the container adjacent the squeezable portion and extending within the fluid receiving volume. The method comprises the steps of applying compressional forces to the squeezable portion of the container to urge the fluid from the fluid receiving volume into the body cavity; releasing the compressional forces to allow the squeezable portion to expand and to withdraw the fluid from the body cavity into the fluid receiving volume; and repeating the above steps.
