Administration set including burette with pivotable air valve |
摘要 |
An administration set including a burette with an air valve communicating with the burette chamber. The air valve comprises a stationary port extending from a top portion of the burette chamber with a fitting closing the port except for a small passageway defined by a top portion of the fitting. A pivotable closure overlies the port and is pivotally connected therewith. The pivotable closure defines an opening for communication with the small passageway when the closure is pivoted to a predetermined open position. The closure opening and the passageway are segregated when the closure is not in the predetermined open position. A filter member is received within the port and directly underlies the small passageway.
