Document Type and Number:
WIPO Patent Application WO/2021/093055
Kind Code:
A1
Abstract:
A medical liquid inlet assembly (1), a medical flushing device, and a medical water jet cutter. The medical liquid inlet assembly (1) comprises a liquid inlet tube (11) in which a liquid inlet channel (111) is defined; the two ends of the liquid inlet tube (11) are respectively a liquid inlet end (112) and a liquid outlet end (113); a position of the liquid inlet tube (11) close to the liquid outlet end (113) is provided with an air discharge port (114) communicated with the liquid inlet channel (111) and the external environment; a waterproof and air-permeable filter element (12) is provided at the air discharge port (114). The structure is simple, the air discharge reliability can be ensured, air can be discharged by means of a gravity action of liquid in the liquid inlet tube (11), the air discharge time can be shortened, no-load idling of a hydraulic pump (3) can be reduced, and abnormal wear and mechanical failures can be reduced.
