Abstract
The present invention relates to a tracheal coupling comprising a patient port 33, an outlet port 36, an inlet port 31 between the patient port and the outlet port, such that flow 34 from the inlet port can go to the patient port or direct to the outlet port, and a flow restriction e.g. 32 between the inlet port and the outlet port, or at the outlet port.
Claims20
A tracheal connector comprising:
- a patient port adapted for connecting to a trachea interface in or on a patient;
- an outlet end comprising an outlet port and at least one aperture, the outlet port configured to release exhaled gases and uninhaled gases;
- an inlet port between the patient port and the outlet end, the inlet port configured to deliver gases to the patient port;
- and
- a blocking element engageable with the outlet end and configured to block a portion of the at least one aperture, wherein the tracheal connector is configured so that for all positions of the blocking element a portion of the at least one aperture remains exposed for fluid flow out of the tracheal connector.
