US Patent 9022036 Patient ventilating and aspirating system

A patient ventilating (23) and aspirating system (8) is disclosed that has a suction tube (9) and connector (6) for connecting to a catheter mount that has a scaled passageway (15). The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount.
