Abstract

A method of operating an electrotherapy device that provides advantages over prior art approaches. In one embodiment, the electrotherapy device stores collected information in a detachable memory device and uses a clock within the memory device to associate a time information with the electrotherapy information. The time information is useful for producing later reports or displays of the collected information by the electrotherapy device or by another device to which the detachable memory device has been attached. The invention is also an electrotherapy system including: an electrotherapy device, the electrotherapy device including a memory device port; and a memory device, the memory device including a connector adapted to be connected to the electrotherapy device memory port, a clock, and a digital memory.

Claims

1. A method of operating an electrotherapy device comprising the following steps:

using the electrotherapy device to collect electrotherapy information;

using a clock in the memory device to associate time information with the electrotherapy information; and

storing the electrotherapy information and the time information on a detachable memory device.

2. The method of claim 1 wherein the step of using the electrotherapy device to collect electrotherapy information comprises collecting electrotherapy information automatically.

3. The method of claim 1 wherein the step of using the electrotherapy device to collect electrotherapy information comprises entering electrotherapy information manually.

4. The method of claim 1 wherein the storing step comprises storing the information on a PC data card.

5. The method of claim 1 further comprising, prior to the storing step, identifying a detachable memory device attached to the electrotherapy device, the storing step comprising storing the electrotherapy information and the time information on the detachable memory device.

6. The method of claim 1 wherein the memory device comprises a digital memory, the method comprising erasing a section of the digital memory prior to the storing step.

7. The method of claim 1 wherein the memory device comprises first and second digital memories, the method comprising erasing the first digital memory and the storing step comprising storing electrotherapy information and time information in the second digital memory during the erasing step.

8. The method of claim 1 further comprising using a clock in the electrotherapy device to associate time information with the electrotherapy information.

9. An electrotherapy system comprising:

an electrotherapy device, the electrotherapy device comprising a memory device port; and

a memory device, the memory device comprising a connector adapted to be connected to the electrotherapy device memory port, a clock, and a digital memory.

10. The electrotherapy system of claim 9 wherein the electrotherapy device further comprises means for using the clock to associate time information with electrotherapy information collected by the electrotherapy device.

11. The electrotherapy system of claim 9 wherein the memory device further comprises an identifier, the electrotherapy device further comprising means for identifying a memory device connected to the memory port.

12. The electrotherapy device of claim 9 wherein the digital memory is a first digital memory, the memory device further comprising a second digital memory, the electrotherapy device further comprising means for erasing the first digital memory while storing electrotherapy information and time information in the second digital memory.
