Abstract

A data collection unit obtains physiological data from a subject interface on a subject. The subject interface can be connected to the data collection unit. When the subject interface is connected to the data collection unit, subject interface contacts on the subject interface make contact with data collection unit contacts on the data collection unit. Some of the data collection unit contacts are for communicating physiological data from the subject interface to the data collection unit. Some of the contacts are for powering the data collection unit upon the subject interface being connected to the data collection unit and for powering down the data collection unit upon the subject interface being disconnected from the data collection unit.

Claims

1. A subject electro-cardiogram (ECG) data collection device comprising:

a removable ECG subject interface having subject interface contacts;

a power source;

a data collection unit comprising;

a processor programmed to obtain physiological data from the ECG subject interface and store the physiological data in non-volatile memory,

a data connector configured to be physically connected to a universal data port on a computer, and

data collection unit contacts configured to be physically connected to the subject interface contacts on the ECG subject interface;

the data collection device configured to provide power from the power source to the processor upon the ECG subject interface being connected to the data collection unit contacts and to interrupt power from the power source upon disconnection of the ECG subject interface from the data collection unit contacts.

2. The device of claim 1, wherein the ECG subject interface comprises a lead-wire set.

3. The device of claim 1, wherein the ECG subject interface includes the power source.

4. The device of claim 1, wherein the data collection unit comprises the non-volatile memory.

5. The device of claim 1, wherein the data connector comprises a male USB connector.

6. The device of claim 1, wherein the data collection device is further configured to detect power provided by the computer when the data connector is connected to the computer and to upload the physiological data stored in the non-volatile memory to a remote service center via the computer when the data connector is connected to the computer.

7. The device of claim 1, wherein the data collection unit is configured to stop providing power from the power source when the ECG subject interface is disconnected from the data collection unit contacts.

8. The device of claim 1 wherein the subject interface contacts comprise a first subject interface contact and a second subject interface contact that:

when not connected to a corresponding first data collection unit contact and a second data collection unit contact, are configured to create an open circuit, and

when connected to the corresponding first data collection unit contact and a second data collection unit contact, are configured to create a closed circuit.

9. The device of claim 8,

wherein the first data collection unit contact is in series with the second data collection unit contact;

and

wherein the ECG subject interface, when connected to the data collection unit contacts, is configured to bring the first data collection unit contact into electrical connection with the second data collection unit contact.

10. The device of claim 8, wherein the subject interface contacts comprise a third subject interface contact and a fourth subject interface contact for bringing electrodes on the ECG subject interface into electrical communication with the processor.

11. The device of claim 1, wherein the data collection unit is further configured to automatically obtain data from the ECG subject interface upon the ECG subject interface being connected to the data collection unit

12. The device of claim 11, wherein the data collection unit is further configured to automatically stop obtaining data from the ECG subject interface upon the ECG subject interface being disconnected from the data collection unit.

13. The device of claim 1, wherein the subject interface comprises a fifth subject interface contact that is configured to interrupt the processor when the ECG subject interface is disconnected from data collection unit contacts.

14. A method comprising:

powering an electro-cardiogram (ECG) data collection unit upon an ECG subject interface being physically connected to the ECG data collection unit, the connected ECG subject interface creating a closed circuit with a power source for powering the ECG data collection unit;

obtaining, using a processor, data from the ECG subject interface and storing the data on non-volatile memory; and

powering-off the ECG data collection unit upon the ECG subject interface being physically disconnected from the ECG data collection unit and thereby creating an open circuit with the power source.

15. The method of claim 14, wherein the ECG subject interface comprises a lead-wire set.

16. The method of claim 14, wherein the obtaining and the storing comprises obtaining and storing the data on non-volatile memory automatically upon the ECG subject interface being physically connected to the ECG data collection unit.

17. The method of claim 14, further comprising:

automatically initiating an upload, over a network, of the data stored on the non-volatile memory to a remote service center via a computer upon a data connector on the data collection unit being physically connected to the computer.

18. The method of claim 17,

wherein the data connector comprises a male USB connector;

and

wherein connecting the data connector on the ECG data collection unit with the computer comprises connecting the USB connector with the computer.

19. The method of claim 14,

wherein the ECG data collection unit comprises a first data collection unit contact and a second data collection unit contact;

wherein being physically connected comprises bringing the first data collection unit contact into electrical communication with the second data collection unit contact via the ECG subject interface and thereby closing the circuit with the power source.

20. The method of claim 19,

wherein the data collection unit comprises a third data collection unit contact and a fourth data collection unit contact;

and

wherein being physically connected comprises bringing a first and second electrodes on the ECG subject interface into electrical communication with the processor via the third data collection unit contact and the fourth data collection unit contact.

21. The method of claim 20,

wherein the data collection unit comprises a fifth data collection unit contact that contacts a fifth subject interface contact on the ECG subject interface when the ECG subject interface is connected to the data collection unit;

and

further comprising sending an interrupt signal to the processor from the fifth electrical contact when the ECG subject interface is disconnected from the ECG data collection unit.

22. The method of claim 14, wherein the ECG subject interface comprises the power source.
