Body fluid suction device indicators

摘要: A medical suction device is disclosed which includes a vacuum indicator flag. This flag made up of flexible tube capped with plug. The rigidity the walls chosen such that collapse when pressure inside falls below predetermined value, thereby allowing to droop. In addition serves hold upright rises above second value. Thus state (upright or drooped) provides remote indication being developed by device. addition, uses constant force coiled ribbon spring provide substantially as filled. Furthermore, plurality separately valved drainage receptacles can be folded and stored compactly against By sequentially filling each these then removing respective receptacle from only after isolation valve has been closed, relatively large volumes drained without opening atmosphere.
