Respiratory therapy condensation adaptor
Systems, devices, and methods for coupling a tracheostomy tube to a source of humidified breathing gas are disclosed. An adaptor includes a housing, a tracheostomy tube connection device, and a baffle. The housing has an interior surface, an exterior surface, and a breathing gas port. The tracheostomy tube connection device is positioned within the housing and includes an input port for receiving a flow of humidified breathing gas from the breathing gas port and an output port for coupling with the tracheostomy tube. The tracheostomy tube connection device has an internal surface defining a breathing gas passage and an external surface spaced from the interior surface of the housing to create a condensation passage. The baffle may be positioned between the breathing gas port and the input port to cause controlled condensation from the flow of humidified breathing gas by disrupting the flow of humidified breathing gas.
1. An adaptor for coupling a tracheostomy tube to a source of humidified breathing gas, the adaptor comprising:
an input port configured to receive a flow of humidified breathing gas;
a breathing gas passage for coupling with the tracheostomy tube;
a condensation passage;
a baffle positioned between the input port and the breathing gas passage, the baffle configured to disrupt the flow of humidified breathing gas to cause controlled condensation from the flow of humidified breathing gas into the condensation passage;
at least one projection, positioned within the condensation passage, to space the breathing gas passage from the condensation passage;
an aperture at a top end of the adaptor configured to allow breathing gas to exit the adaptor; and
a vent cap positioned above the aperture, the vent cap configured such that condensate that accumulates on the vent cap flows into the condensation passage.
2. The adaptor of claim 1 , wherein the condensation passage comprises a top end and a bottom end, and wherein the condensation passage is configured such that condensation flows towards the bottom end.
3. The adaptor of claim 2 , wherein the bottom end of the condensation passage is located opposite the input port.
4. The adaptor of claim 3 , wherein the bottom end of the condensation passage is open and configured such that condensation exits the adaptor at the bottom end.
5. The adaptor of claim 4 , wherein the bottom end of the condensation passage is configured to serve as a vent for exhaled air.
6. The adaptor of claim 1 , wherein the condensation passage surrounds at least a portion of the breathing gas passage.
7. The adaptor of claim 1 , wherein the vent cap includes an aperture configured to allow breathing gas to exit the adaptor.
8. The adaptor of claim 1 , wherein the baffle is integrally formed with the input port.
9. The adaptor of claim 1 , wherein the baffle includes an arcuate upper edge.
10. The adaptor of claim 1 , wherein the baffle extends above an upper edge of the input port.
11. The adaptor of claim 1 , further comprising a tracheotomy tube connection device extending within the condensation passage.
12. The adaptor of claim 11 , wherein the tracheotomy tube connection device defines at least a portion of the breathing gas passage.
13. The adaptor of claim 1 , wherein the adaptor further comprises a tube sleeve configured to receive a suction tube to suction away secretions in an airway of a patient.
14. The adaptor of claim 13 , further comprising the suction tube, the suction tube having a first tube end and a second tube end, the first tube end extending out of the adaptor for coupling with a suctioning apparatus and the second tube end configured to extend into the airway of a patient to suction away secretions when positioned within the tube sleeve.
15. The adaptor of claim 14 , wherein the tube sleeve is fixedly bonded to a surface of a tracheostomy tube connection device and the second tube end extends through the tube sleeve so as to be capable of extending into the airway of the patient.
16. An adaptor for coupling a tracheostomy tube to a source of humidified breathing gas, the adaptor comprising:
a housing having means for receiving a flow of humidified breathing gas from the source;
a tracheostomy tube connection device having means for connecting the housing to the tracheostomy tube;
means for causing controlled condensation from the flow of humidified breathing gas by disrupting the flow of humidified breathing gas into the housing;
means for causing the controlled condensation to exit the adaptor;
at least one projection, positioned within the housing and extending from a surface of the tracheotomy tube connection device, to space the tracheostomy tube connection device from an interior surface of the housing;
an aperture at a top end of the adaptor configured to allow breathing gas to exit the adaptor; and
a vent cap positioned above the aperture, the vent cap configured such that condensate that accumulates on the vent cap flows into the housing.
17. The adaptor of claim 16 , wherein the means for causing controlled condensation are integrally formed with the means for connecting the housing to the tracheostomy tube.
