Abstract

An electronic pain feedback system for use by a patient in determining the effectiveness of a pain treatment. The system includes an input device connected to a memory device. The input device includes a scale on which the patient enters perceived pain level data to initiate the pain treatment. The input device signals this data to the memory device where it is recorded. The electronic pain feedback system can alternatively include a dock and intensity sensor for recording a treatment session duration and intensity. The data received and recorded can be used by the electronic pain feedback system to evaluate the effectiveness of the pain treatment.

Claims

1. An electronic pain feedback system for recording a perceived level of pain by a patient, the system comprising:

an input device, including a scale for receiving data regarding a level of pain experienced by a patient, wherein the input device supplies a signal representative of the data;

a pain treatment device for administering a pain treatment in response to the input device receiving data regarding a level of pain; and

a memory device connected to the input device for receiving the signal and storing the signal representative of the data regarding the level of pain experienced by a patient.

2. The electronic pain feedback system of claim 1, wherein the scale includes a plurality of indicator zones, each of the plurality of indicator zones representing a different level of pain.

3. The electronic pain feedback system of claim 1, further including:

an output device for displaying the data stored in the memory device.

4. The electronic pain feedback system of claim 1 wherein the pain treatment device initiates pain treatment in response to a first signal from the input device and ends pain treatment in response to a second signal from the input device.

5. The electronic pain feedback system of claim 1, wherein the pain treatment device is a transcutaneous electrical nerve stimulation system.

6. The electronic pain feedback system of claim 1, wherein the scale includes:

a first membrane switch representing a first level of pain; and

a second membrane switch representing a second level of pain.

7. The electronic pain feedback system of claim 1, wherein the scale is a continuous membrane.

8. A patient interactive system for treatment of pain of a patient, the system comprising:

an electronic pain rating device for receiving data from a patient indicating a perceived level of pain experienced, the electronic pain rating device supplying a pain level signal representative of the data; and

a pain treatment device connected to the electronic pain rating device for receiving the pain level signal and for administering varying levels of pain treatment to a patient, wherein the pain treatment is activated upon receiving the pain level signal produced by the electronic pain rating device.

9. The system for treatment of pain of claim 8, further comprising:

a memory device for receiving and storing the pain level signal from the electronic pain rating device.

10. The system for treatment of pain of claim 9, wherein the memory device is a microcontroller.

11. The system for treatment of pain of claim 9, further including:

a voltage detector connected to the electronic pain rating device and connected to the memory device for receiving the signal produced and for transmitting a voltage signal to the memory device, thereby permitting the memory device to record the data regarding a level of pain.

12. The system for treatment of pain of claim 9, further including:

a clock connected to the pain treatment device and to the memory device, wherein the clock registers a time period of activation of the pain treatment and transmits a duration signal representative of the time period to the memory device.

13. The system for treatment of pain of claim 9, further including:

an intensity sensor connected to the pain treatment device and the memory device, wherein the intensity sensor reads an intensity of pain treatment from the pain treatment device and transmits an intensity signal representative of the intensity to the memory device.

14. The system for treatment of pain of claim 9, further including:

a display device for displaying the pain level signal recorded by the memory device.

15. The system for treatment of pain of claim 9, further including:

a processing means connected to the memory device for constructing a statistical trend from the pain level signal stored in the memory device.

16. The system for treatment of pain of claim 8, wherein the pain treatment device is a tramcutaneous electrical nerve stimulation system.

17. The system for treatment of pain of claim 8, wherein the pain treatment device is a drug dispensing system.

18. An interactive method of monitoring effectiveness of pain treatment for a patient, the method comprising:

receiving data from an electronic pain rating device representing a beginning level of pain experienced by the patient;

storing the beginning level of pain;

activating the pain treatment in response to the data;

setting a level of pain treatment administered to the patient; and

storing the level of pain treatment.

19. The method of claim 18, further including:

deactivating the pain treatment.

20. The method of claim 19, further including:

measuring a time period from activating the pain treatment to deactivating the pain treatment; and

storing the time period.

21. The method of claim 18, further including:

receiving data from the electronic pain rating device regarding an ending level of pain experienced by the patient; and

recording the ending level of pain.

22. An interactive method of monitoring effectiveness of a pain treatment for a patient, the method comprising:

receiving initial data from an electronic pain rating device representing a beginning level of pain experienced by a patient;

activating the pain treatment in response to the initial data;

setting a level of pain treatment administered to the patient;

receiving final data from the electronic pain rating system regarding an ending level of pain experienced by the patient;

deactivating the pain treatment device in response to the final data;

sensing a time period from activating the pain treatment to deactivating the pain treatment;

storing the beginning level of pain;

storing the ending level of pain;

storing the level of pain treatment administered to the patient; and

storing the time period.
