1. A patient ventilating and aspirating system, comprising:
- a gases transport conduit adapted to convey pressurized gases in use to a patient,a patient connector adapted to deliver said pressurized gases through a tracheostomy or endotracheal tube fitting, said patient connector adapted to be in fluid communication with said gases transport conduit in use,a catheter mount that is substantially tubular and adapted to be fitted in use between said patient connector and said gases transport conduit, said catheter mount adapted to convey said pressurized uses from said uses transport conduit to said patient connector and maintain PEEP in the system, said catheter mount including a passageway for receiving an aspirating system, said passageway covered by a seal located on an outer edge of said passageway, said seal including a re-sealing mechanism and configured to provide a substantially airtight seal at normal operating pressures such that said catheter mount is sealed from atmosphere in use, anda suction tube, with a distal end and a proximal end, surrounded by a collapsible envelope, said distal end fitted with a distal connector and said proximal end being moveable through a proximal connector attached to said envelope, said distal connector adapted to allow said distal end of said suction tube to be connected to a suction means in use, said proximal connector being releasably connected to said catheter mount with a bayonet fitting, said proximal connector including a piercing member capable of piercing said seal when said proximal connector and said catheter mount are connected, said suction tube capable of passing through said piercing member and not contacting said seal.

Abstract
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.
