Abstract

This document discusses, among other things, an apparatus and method for receiving biomedical data of a patient. Biomedical data of the patient can be wirelessly received using a wireless sensor base station including a transceiver to receive the biomedical data from a wireless sleep sensor. A demultiplexer of the wireless sensor base station can separate respiration information from the biomedical data. Examples include providing the biomedical data to a polysomnograph (PSG) machine or a sleep therapy device using an output of the wireless sensor base station.

Claims

1. An apparatus for receiving biomedical data from a patient, the apparatus comprising:

a transceiver configured to wirelessly receive biomedical data from a wireless sleep sensor;

a demultiplexer coupled to the transceiver, the demultiplexer configured to separate respiration information from the received biomedical data; and

an output coupled to the demultiplexer, the output configured to provide the respiration information to a polysomnograph machine or a sleep therapy device.

2. The apparatus of claim 1, wherein the transceiver is configured to receive respiration airflow information from a wireless respiration sleep sensor.

3. The apparatus of claim 1, wherein the demultiplexer is configured to separate respiration airflow information from the received biomedical data.

4. The apparatus of claim 1, wherein the respiration airflow information includes respiration temperature and pressure information of inspiration airflow and expiration airflow of the patient;

and

wherein the multiplexer is configured to maintain a phase relationship of the respiratory temperature and pressure information.

5. The apparatus of claim 1, wherein the transceiver is configured to receive chest respiratory effort information from a wireless chest respiratory effort belt.

6. The apparatus of claim 1, wherein the demultiplexer is configured to separate chest respiratory effort information from the received biomedical data.

7. The apparatus of claim 1, wherein the transceiver is configured to receive abdominal respiratory effort information from a wireless abdominal respiratory effort belt.

8. The apparatus of claim 1, wherein the demultiplexer is configured to separate abdominal respiratory effort information from the received biomedical data.

9. The apparatus of claim 1, wherein the transceiver is configured to receive respiration airflow information from a wireless respiration sleep sensor, chest respiratory effort information from a wireless chest respiratory effort belt, and abdominal respiratory effort information from a wireless abdominal respiratory effort belt.

10. The apparatus of claim 1, wherein the demultiplexer is configured to separate respiration airflow information, chest respiratory effort information, and abdominal respiratory effort information from the received biomedical data.

11. A method for receiving biomedical data from a patient, the method comprising:

receiving biomedical data from a wireless sleep sensor at a transceiver;

separating respiration information from the received biomedical data using a demultiplexer; and

providing the respiration information to a polysomnograph (PSG) machine or a sleep therapy device.

12. The method of claim 11, wherein the receiving the biomedical data includes receiving respiration airflow information from a wireless respiration sensor.

13. The method of claim 11, wherein the separating includes separating respiration airflow information from the biomedical data.

14. The method of claim 12, wherein the respiration airflow information includes respiration temperature and pressure information of inspiration airflow and expiration airflow of the patient;

and

wherein the separating includes maintaining a phase relationship of the respiration temperature and pressure information.

15. The method of claim 11, wherein the receiving the biomedical data includes receiving chest respiratory effort information from a wireless chest respiratory effort belt.

16. The method of claim 11, wherein the separating includes separating chest respiratory effort information from the received biomedical data using a demultiplexer.
