Abstract

A physiological sensing device comprises, in combination a sensor (4) for the measurement of the partial pressure of carbon dioxide (pCO₂), a body temperature sensor (5) and a heart rate and oxygen saturation sensor (54). The sensor device can be used to continuously monitor the vital signs of a patient.

Claims

1. A physiological sensing device comprising in combination:

a sensor for the measurement of the partial pressure of carbon dioxide (pCO2);

a body temperature sensor;

a heart rate sensor; and

;

an oxygen saturation sensor.

2. A sensing device as claimed in claim 1, wherein the pCO2 sensor is configured for insertion through a patient'"'"'s skin.

3. A sensing device as claimed in claim 1, wherein the temperature sensor is configured for insertion through a patient'"'"'s skin.

4. A sensing device as claimed in claim 1, wherein the temperature sensor and the pCO2 sensor are provided by a sensor unit for insertion through a patient'"'"'s skin.

5. A sensing device as claimed in claim 2 wherein the device comprises a sharp tip for puncturing a patient'"'"'s skin on insertion of the pCO2 sensor.

8. A sensing device as claimed in claim 1, wherein the oxygen saturation sensor is configured for application to the surface of a patient'"'"'s skin.

9. A sensing device as claimed in claim 8, wherein the heart rate sensor and the oxygen saturation sensor are provided by a pulse oxymetry sensor.

10. A sensing device as claimed in claim 1 comprising an adhesive patch for adhering the device to a patient'"'"'s skin.

12. A sensing device as claimed in claim 1, wherein the pCO2 sensor comprises a chamber bounded, at least in part, by a carbon dioxide permeable membrane and containing a substantially electrolyte-free liquid and at least two electrodes.

15. A sensing device as claimed in claim 5, wherein the sharp tip is provided by a removable hollow needle in which the pCO2 sensor is located for insertion through a patient'"'"'s skin.

6. A physiological sensing device comprising

a pCO2 sensor configured for insertion through a patient'"'"'s skin and

a sharp tip for puncturing a patient'"'"'s skin on insertion of the pCO2 sensor.

7. A sensing device as claimed in claim 6, wherein the sharp tip is provided by a removable hollow needle in which the pCO2 sensor is located for insertion through a patient'"'"'s skin.

13. A sensing device as claimed in claim 6, wherein the pCO2 sensor comprises a chamber bounded, at least in part, by a carbon dioxide permeable membrane and containing a substantially electrolyte-free liquid and at least two electrodes.

16. A sensing device as claimed in claim 6 comprising an adhesive patch for adhering the device to a patient'"'"'s skin.

11. A physiological sensing device comprising

a pCO2 sensor configured for insertion through a patient'"'"'s skin and

an ablest patch for adhering the device to a patient'"'"'s skin to retain the inserted pCO2 sensor in position.

14. A sensing device as claimed in claim 11, wherein the pCO2 sensor comprises a chamber bounded, at least in part, by a carbon dioxide permeable membrane and containing a substantially electrolyte-free liquid and at least two electrodes.
