Abstract

A temperature variable and iontophoretic device for application to the body of a patient has an outer support member coupled to a device for selectively applying thermal energy to the body of a patient or for removing thermal energy therefrom, and a further device for selectively energizing the thermal energy supply and removal device. Another member is coupled to the outer support member for iontophoretically administering a compound to the body of the patient. The energizing device comprises a user-operable data input device which also controls the iontophoretic administering device. Transcutaneous electrical neurostimulation (TENS) can also be provided.

Claims

1. A temperature variable and iontophoretic device for application to the body of a patient, comprising:

an outer support member;

means coupled to said outer support member for selectively supplying thermal energy to the body of a patient or for removing thermal energy therefrom;

means for selectively energizing said thermal energy supply and removal means for effecting thermal energy supply or removal form the body of the patient, said energizing means comprising a user-operable data input device; and

means coupled to said outer support member for iontophoretically administering a compound to the body of the patient, wherein said data input device also selectively controls said iontophoretic administering means.

2. The device according to claim 1 wherein said thermal energy supply and removal means comprises a deformable member that is positionable against a portion of the body of a patient to assume the general shape of the body portion.

3. The device according to claim 2, wherein said deformable member comprises at least one sealed sac having a heat conductive fluid contained therein.

4. The device according to claim 1 or 2 wherein said support member comprises a flexible structure which is generally conformable to the portion of the patient'"'"'s body over which the device is to be applied.

5. The device according to claim 1, wherein said thermal energy supply and removal means comprises at least one Peltier thermoelectric device.

6. The device according to claim 5, wherein said Peltier thermoelectric device is positioned between said outer support member and a deformable member positionable against a portion of the body of a patient to assume the general shape of the underlying body portion, said deformable member containing a heat conductive fluid.

7. The device according to claim 6, wherein said deformable member comprises an electric field responsive compound.

8. The device according to claim 6, wherein said data input means comprises programmable data processing means.

9. The device according to claim 8, further comprising means for monitoring the temperature of said fluid and feedback control means for controlling said Peltier thermoelectric device in accordance with any disparity between said monitored fluid temperature and a user-selected temperature value input into the processing means.

10. The device according to claim 9, wherein said processing means is operable to receive program input for at least two different user-selected temperature values and to control said Peltier device to effect a change in fluid temperature from one of sad user-selected temperature values to the other of said user-selected temperature values upon attainment of a user-selected parameter.

11. The device according to claim 10, wherein said user-selected parameter is time duration of treatment.

12. The device according to claim 10, wherein at least one of said user-selected temperature values and said user-selected parameter is input into said processing means by input means detachably coupled to said processing means.

13. The device according to claim 1, wherein said iontophoretic administering means comprises means for introducing the compound into the patient'"'"'s body in a user-selectable direction relative to the surface of the patient'"'"'s body to be iontophoretically treated.

14. The device according to claim 13, wherein said compound introducing means comprises first and second electrodes, at least one of said electrodes being selectively positionable along the patient'"'"'s body so as to position the electrodes along a lie that is generally transverse to he surface to be iontophoretically treated.

15. The device according to claim 1, wherein said data input device comprises programmable data processing means.

16. The device according to claim 15, wherein said processing means is operable to receive a user-selected parameter and to terminate an electric field applied by said iontophoretic administering means upon attainment of said user-selected parameter.

17. The device according to claim 16, wherein said use-selected parameter is time duration of treatment.

18. The device according to claim 1, wherein at least a portion of the device is configured as a single use, disposable member.

19. The device according to claim 1, further comprising means coupled to said outer support member for implementing transcutaneous electrical neurostimulation.

20. The device according to claim 19, wherein said transcutaneous electrical neurostimulation implementing means is connected to said data input device, and wherein said data input device comprises a programmable data processing device.

21. The device according to claim 20, wherein said programmable data processing device receives as an input at least one of the following parameters:

elapsed time, electric field strength and voltage wave form.

22. The device according to claim 21, wherein said transcutaneous electrical neurostimulation implementing means and said iontophoresis administering means together comprise at lest two concentric electrodes.

23. A temperature variable device for applying transcutaneous electrical neurostimulation to the body of a patient, comprising:
