CHEST DRAINAGE ANTI-SPILL COUPLING

摘要

An anti-spillover flow coupling for a chest drainage assembly including at least a first and a second flow chamber. The coupling includes an intake port adapted to couple to the first flow chamber and exit port adapted to couple to the second flow chamber. The coupling defines a flow passageway between the intake port and exit port. The flow coupling further includes an anti-spill means for preventing the flow of liquid between the first flow chamber and second flow chamber. The anti-spill means can include a valve means including a ball member and valve seat member, the valve means being open when a valve axis is aligned substantially against the direction of gravity. Or the anti-spill means includes at least one filter element disposed over one of the intake port or exit port, the filter element permitting the passage of gases but not liquids.
