Abstract

A device for detecting tracheostomy tube placement, including a housing having an inner wall forming a cylindrical channel through the housing, the cylindrical channel having a first opening and a second opening, a carbon dioxide sensor embedded in a cutout in the inner wall of the housing, a moisture filter removably affixed to the inner wall, and processing circuitry embedded in the housing and configured to determine a level of carbon dioxide in airflow through the cylindrical channel based on data from the carbon dioxide sensor, generate a waveform representing carbon dioxide levels in the airflow through the cylindrical channel, and determine a placement state of a tracheostomy tube that is removably coupled to the first opening of the cylindrical channel based on analysis of the waveform representing the carbon dioxide levels in the airflow, analysis of the waveform considering a physiological factor of the patient having the tracheostomy tube.

First claim

1 . A device for detecting tracheostomy tube placement, comprising:
a housing having an inner wall forming a cylindrical channel through the housing, the cylindrical channel having a first opening and a second opening; a carbon dioxide sensor embedded in a cutout in the inner wall of the housing; a moisture filter removably affixed to the inner wall; and processing circuitry embedded in the housing and configured to
determine a level of carbon dioxide in airflow through the cylindrical channel based on data from the carbon dioxide sensor,
generate a waveform representing carbon dioxide levels in the airflow through the cylindrical channel, and
determine a placement state of a tracheostomy tube that is removably coupled to the first opening of the cylindrical channel based on analysis of the waveform representing the carbon dioxide levels in the airflow,
wherein the analysis of the waveform considers at least one physiological factor of a patient having the tracheostomy tube.

2 . The device of claim 1 , wherein the carbon dioxide sensor is an infrared sensor.

3 . The device of claim 1 , wherein the placement state of the tracheostomy tube includes a correct placement, an incorrect placement, a decannulation state, a partial obstruction, or a full obstruction.

4 . The device of claim 1 , further comprising a humidity sensor in contact with the inner wall of the housing.

5 . The device of claim 1 , wherein the first opening of the cylindrical channel is removably coupled to the tracheostomy tube with a press-fit joint.

6 . The device of claim 1 , wherein the processing circuitry is further configured to transmit the waveform representing carbon dioxide levels and the placement state of the tracheostomy tube to a user device via a wireless connection or transmit an alert to the user device based on the placement state of the tracheostomy tube via the wireless connection.

7 . The device of claim 6 , wherein the at least one physiological factor includes an age of the patient.

8 . A device for detecting tracheostomy tube placement, comprising:
a housing having an inner wall forming a cylindrical channel through the housing, the cylindrical channel having a first opening and a second opening; a carbon dioxide sensor embedded in the inner wall of the housing; and processing circuitry embedded in the housing and configured to
determine a level of carbon dioxide in airflow through the cylindrical channel based on data from the carbon dioxide sensor,
generate a waveform representing carbon dioxide levels in the airflow through the cylindrical channel, and
determine a placement state of a tracheostomy tube that is removably coupled to the first opening of the cylindrical channel based on the waveform representing carbon dioxide levels in the airflow.

9 . The device of claim 8 , wherein the carbon dioxide sensor is an infrared sensor.

10 . The device of claim 8 , wherein the placement state of the tracheostomy tube includes a correct placement, an incorrect placement, a decannulation state, a partial obstruction, or a full obstruction.

11 . The device of claim 8 , further comprising a humidity sensor in contact with the inner wall of the housing.

12 . The device of claim 8 , wherein the first opening of the cylindrical channel is removably coupled to the tracheostomy tube with a press-fit joint.

13 . The device of claim 8 , wherein the processing circuitry is further configured to transmit the waveform representing carbon dioxide levels and the placement state of the tracheostomy tube to a user device via a wireless connection.

14 . The device of claim 13 , wherein the processing circuitry is further configured to transmit an alert to the user device based on the placement state of the tracheostomy tube via the wireless connection.

15 . A tracheostomy tube, comprising:
a cannula; a flange at a proximal end of the cannula; a carbon dioxide sensor embedded in an inner wall of the cannula at the proximal end of the cannula; and a housing containing processing circuitry that is removably coupled to the flange, wherein the processing circuitry is configured to
determine a level of carbon dioxide in airflow through the cannula based on data from the carbon dioxide sensor,
generate a waveform representing carbon dioxide levels in the airflow through the cannula, and
determine a placement state of the tracheostomy tube based on the waveform of carbon dioxide levels in the airflow.

16 . The tracheostomy tube of claim 15 , wherein the carbon dioxide sensor is an infrared sensor.

17 . The tracheostomy tube of claim 15 , wherein the housing is removably coupled to the flange via a strap that is configured to wrap around the flange.

18 . The tracheostomy tube of claim 15 , wherein the placement state of the tracheostomy tube includes a correct placement, an incorrect placement, a decannulation state, a partial obstruction, or a full obstruction.

19 . The tracheostomy tube of claim 15 , wherein the processing circuitry is further configured to transmit the waveform representing carbon dioxide levels and the state of the tracheostomy tube to a user device via a wireless connection.

20 . The tracheostomy tube of claim 19 , wherein the processing circuitry is further configured to transmit an alert to the user device based on the placement state of the tracheostomy tube via the wireless connection.
