Abstract

An apparatus for patient oxygen supply monitoring includes a housing, a microcontroller, at least one sensor, and a power supply. The housing has at least one port for mechanically coupling to a gas supply tube of an oxygen gas delivery system. The microcontroller is positioned within the housing, and the at least one sensor is operably coupled to the microcontroller and positioned within the housing. The power supply is positioned within the housing and configured to supply power, during operation, to the microcontroller and to the at least one sensor. The microcontroller monitors the oxygen gas delivery system by receiving data generated by the at least one sensor when the at least one port is mechanically coupled to the gas supply tube and when oxygen is flowing through the at least one port.

Claims (30)

1 . An apparatus, comprising:

a housing having at least one port defined therein, a first port from the at least one port configured to mechanically couple to a dual lumen gas supply tube of an oxygen gas delivery system;

a microcontroller disposed within the housing;

a first sensor operably coupled to the microcontroller and disposed within the housing, the first sensor aligned with a first lumen of the dual lumen gas supply tube when the at least one port is mechanically coupled to the dual lumen gas supply tube;

a second sensor different from the first sensor and operably coupled to the microcontroller and disposed within the housing, the second sensor aligned with a second lumen of the dual lumen gas supply tube and not the first lumen when the at least one port is mechanically coupled to the dual lumen gas supply tube; and

a power supply disposed within the housing and configured to supply power, during operation, to the microcontroller, the first sensor, and the second sensor,

the microcontroller configured to perform monitoring of the oxygen gas delivery system, the monitoring including receiving data generated by at least one of the first sensor or the second sensor when the at least one port is mechanically coupled to the dual lumen gas supply tube and when oxygen is flowing through the at least one port.

2 . The apparatus of claim 1 , wherein the at least one port includes a hose barb.

3 . The apparatus of claim 1 , wherein at least one of the first sensor or the second sensor includes an oxygen flow sensor.

4 . The apparatus of claim 1 , wherein at least one of the first sensor or the second sensor includes a differential pressure sensor.

5 . The apparatus of claim 1 , wherein the first sensor includes an oxygen flow sensor and the second sensor includes a differential pressure sensor.

6 . The apparatus of claim 1 , wherein:

at least one of the first sensor or the second sensor includes an oxygen flow sensor, and

the oxygen flows through the oxygen flow sensor when the at least one port is mechanically coupled to the dual lumen gas supply tube and when the oxygen is flowing through the at least one port.

7 . The apparatus of claim 1 , wherein the at least one port includes a second port configured to mechanically couple to an oxygen administration assembly.

8 . The apparatus of claim 7 , wherein the oxygen administration assembly includes one of a nasal cannula, a face mask, or a transtracheal catheter.

9 . A method, comprising:

monitoring an operation of an oxygen gas delivery system by:

detecting, via an oxygen supply monitor coupled via a t-connector to the oxygen gas delivery system and during operation of the oxygen gas delivery system, at least one of an oxygen flow or an air pressure indicative of an inhalation event, the oxygen supply monitor being coupled to the oxygen gas delivery system in one of an in-line configuration or an offset configuration; and

at least one of storing or causing transmission of data generated by the oxygen supply monitor during the operation of the oxygen gas delivery system, based on the detecting of the at least one of the oxygen flow or the air pressure indicative of the inhalation event,

the oxygen gas delivery system including a dual lumen cannula, and

the oxygen supply monitor including a first sensor operably coupled to a microcontroller and aligned with a first lumen of the dual lumen cannula, and a second sensor different from the first sensor and operably coupled to the microcontroller, the second sensor aligned with a second lumen of the dual lumen cannula.

10 . The method of claim 9 , wherein the oxygen supply monitor is coupled to the oxygen gas delivery system via at least one barbed hose fitting.

11 . The method of claim 9 , further comprising receiving, at the oxygen supply monitor, remote sensor data representing a physiological parameter of a patient to whom oxygen is being administered via the gas delivery system.

12 . The method of claim 9 , further comprising:

detecting an alert condition based on the data generated by the oxygen supply monitor during the operation of the oxygen gas delivery system, and

generating an alert in response to detecting the alert condition.

13 . The method of claim 9 , further comprising predicting a prospective acute healthcare event based on the data generated by the oxygen supply monitor during the operation of the oxygen gas delivery system.

14 . The method of claim 9 , wherein the oxygen supply monitor is coupled to the oxygen gas delivery system in the offset configuration and via a splitter.

15 . The apparatus of claim 1 , wherein the microcontroller is further configured to predict a prospective acute healthcare event based on the data generated by the at least one of the first sensor or the second sensor during the operation of the oxygen gas delivery system.
