Abstract

A device having an arterial pulse sensor that is adhered to the hypothenar region of a palm using an adhesive patch. The patch has an adhesive surface that is covered by a removable film with an outer portion and a central portion. Also disclosed is a method of detecting an arterial pulse by providing an arterial pulse sensor, placing the sensor on the hypothenar region of the palm of a hand, and receiving an arterial pulse signal from the sensor.

Claims

1. A device for detecting arterial pulse signals from an artery comprising:

an arterial pulse sensor; and

attaching means for holding the sensor on the hypothenar region of the palm of a hand.

2. The device of claim 1, further comprising a data processing unit for receiving arterial pulse signals from the pulse sensor wherein the data processing unit is in signal communication with the pulse sensor.

3. The device of claim 1, wherein the signal communication is wired or wireless.

4. The device of claim 1, wherein the arterial pulse sensor is a photoplethysmographic sensor.

5. The device of claim 1, further comprising a motion sensor.

6. The device of claim 5, wherein the motion sensor is selected from the group consisting of an accelerometer and a piezo sensor.

7. The device of claim 5, further comprising an adaptive filter.

8. The device of claim 7, wherein the motion sensor is a three-axis accelerometer and the adaptive filter is adapted to obtain reference signals from the three-axis accelerometer.

9. The sensor of claim 7, wherein the adaptive filter is selected from the group consisting of LMS, RLS and Kainan.

10. The device of claim 1, wherein the attaching means is selected from the group consisting of an adhesive, a glove, and a spring biased mechanism.

11. The device of claim 1, in combination with an ECG sensor whereby arterial pulse wave velocity can be aquired.

12. An adhesive patch for adhering a sensor to a hypothenar area of a palm, the adhesive patch comprising:

a first adhesive region for adhering the sensor to the patch; and

a second adhesive region for adhering the patch to the palm.

13. The patch of claim 12, further including:

a first removable film for covering the first adhesive surface; and

a second removable film for covering the second adhesive surface.

14. The adhesive patch of claim 12, wherein the first adhesive region defines an area at or near the centre of the adhesive patch.

15. The patch according to claim 12, wherein the first adhesive region is sized and shaped to receive the sensor.

16. The patch according to claim 12, further including an opening in the patch for receiving a cable.

17. The patch of claim 12, further comprising an adhesive pad fixed to the adhesive surface between the adhesive surface and the central portion of the film.

18. A method of detecting an arterial pulse comprising the steps of:

providing an arterial pulse sensor;

placing the sensor on the hypothenar region of the palm of a hand; and

receiving an arterial pulse signal from the sensor.

19. The method of claim 18, further comprising the step of providing a data processing unit for receiving and processing the arterial pulse signal.

20. The method of claim 18, further comprising the step of providing a display device and displaying the processed signal on the device.
