Estimating the term…
A connector is provided for coupling with an invasive patient interface for providing respiratory support to a patient. The connector comprises a connector body having: (i) an inlet port couplable with a flow source providing a flow of respiratory gas; (ii) a gases exit port; and (iii) a device port couplable with the invasive patient interface. The connector also has a lumen having a first end and a second end. The connector body defines a gas flow path between the inlet port and both the device port and the lumen first end and the lumen second end is disposed outside the device port. The lumen provides improved CO2 clearance. Some embodiments provide for gas sampling and/or variable expiratory resistance.
A connector for coupling with an invasive patient interface providing respiratory support to a patient, the connector comprising:
The connector according to any one of the preceding claims, wherein the lumen second end is disposed, when in use, between the device port and a proximal end of the invasive patient interface.
The connector according to any one of the preceding claims, wherein the target location is within the invasive patient interface, close to a proximal end of the invasive patient interface.
The connector according to any one of the preceding claims, wherein at least part of the lumen is integral with the connector body.
The connector according to any one of the preceding claims, wherein the entire lumen is integral with the connector body.
The connector according to any one of the preceding claims comprising a locating feature for preventing the lumen from protruding out of the invasive patient interface when in use.
The connector according to any one of the preceding claims, configured for releasable coupling and recoupling with an invasive patient interface, either directly or through an adapter device.
The connector according to any one of the preceding claims, wherein the connector body defines a gas outflow path between the device port and the gases exit port.
The connector according to any one of the preceding claims, wherein the connector body defines a gas outflow path between the inlet port, the device port and the gases exit port.
The connector according to any one of the preceding claims, wherein the connector is configured to generate a predetermined airway pressure when coupled with the invasive patient interface in use.
The connector according to any one of the preceding claims, wherein the flow of respiratory gas into the inlet port is divided between the device port, the lumen and the gases exit port.
The connector according to any one of the preceding claims, wherein the inlet port receives a flow of respiratory gas having a flow rate in a range of about 10 LPM to about 150 LPM, preferably about 20 LPM to about 70 LPM.
The connector according to any one of the preceding claims, comprising a filter configured to treat gases in the outflow path.
The connector according to any one of the preceding claims, wherein the invasive patient interface is a sealing interface selected from a group comprising:
A system for providing respiratory support to a patient, the system comprising:
