Hand-held medical evacuator and irrigation device |
摘要 |
A pistol-shaped frame (26) houses a fluid distribution assembly (58), including a plunger (46) operated by a trigger (30) for discharging fluid from a reservoir (60) through an outlet check valve (68). On return of the spring-loaded trigger (30), an inlet check valve (80) allows fluid to be drawn into the reservoir (60). A thumb-operated valve assembly (96) provides a fluid passage between an output (12) of the device and the outlet check valve (68) in one position, and in another position provides a vacuum passage between a vacuum inlet port (104) and the output (12). Trigger graduations (136 ) provide a visual indication of measured amounts of fluid dispensed by the device (10).
