Abstract

A piezoelectric unit (4), preferably a piezoelectric foil, is arranged in a medical plaster unit (13) for therapeutic or stimulating influence of body tissue in an area underneath the plaster unit. The plaster unit may be equipped with a battery (11) and a microcircuit (2) for delivering voltage pulses or oscillations to the piezo unit (4). The plaster unit (13) can possibly be used as part of a system of several plaster units (13) that are activated synchronously to influence one and the same tissues area.

Claims

1. A medical plaster for emitting tissue-influencing energy, comprising a flexible backing layer (1) and an adhesive layer (5), characterized by at least one piezoelectric unit (4) in or on said backing layer (1), as well as an energizing circuit (2) for said unit or units, comprising electronics for delivering pulses or oscillations, said circuit (2) being attached to said backing layer (1) or said adhesive layer (5), possibly said energizing circuit (15) is separate and linked to said plaster via a wire connection (9).

2. The medical plaster of claim 1, characterized in that said energizing circuit (2) is situated on the plaster, and is adapted for control and/or energy supply from another, superior energizing circuit (2) on another similar plaster, for operation in a plaster system.

3. The medical plaster of claim 1, characterized in that said energizing circuit (2) is situated on the plaster, and is adapted for control and/or energy supply to other subordinate energizing circuits (2) on other similar plasters.

4. The medical plaster of one of the previous claims, characterized in that said energizing circuit (2) has its own battery (11).

5. The medical plaster of claim 1 or 3, characterized in that said energizing circuit (2) is situated on the plaster, and is adapted to receive control signals and/or power from an external operating central (14;

17), via wire (9) or in a wireless manner.

6. The medical plaster of one of the previous claims, characterized in that said piezoelectric unit is a piezoelectric foil (4).

7. A medical plaster system for emitting tissue-influencing energy, comprising a number of plaster units (13) each comprising a flexible backing layer (1) and an adhesive layer (5), characterized

in that every plaster unit (13) has at least one piezoelectric unit (4) in or on said backing layer (1),

in that the system has at least one energizing circuit for the piezoelectric units, comprising electronics (2) for delivering pulses or oscillations, and

by connecting means (9) between the plaster units (13) for transmitting control signals regarding interactive piezoelectric activity, possibly also for transfer of power.

8. The medical plaster system of claim 7, characterized in that at least one of said plaster units (13) of the system has its own energizing circuit (2) attached to the backing layer (1) or the adhesive layer (5).

9. The plaster system of claim 7 or 8, characterized in that said connecting means are wires (9) between respective energizing circuits (2), possibly between an energizing circuit (2) on one plaster unit and a piezoelectric unit (4) on another plaster unit (13).

10. The plaster system of claim 9, characterized in that only one plaster unit (13) has a battery (11), whereby the connecting wires (9) are adapted for transmission of control signals and power.

11. The plaster system of claim 8, in which system every plaster unit has its own energizing circuit (2) and its own battery (11), characterized in that said connecting means are wireless connections for transfer of control signals from one of said plaster units (13), the main unit, to the remaining plaster units (13) of the system.

12. The plaster system of claim 11, characterized in that said main unit (13) is connected regarding control and/or power, to an external operating central (14;

17), via wire (9) or in a wireless manner.

13. The plaster system of claim 7, characterized in that it comprises one single separate energizing circuit (15), connected by wire to the piezoelectric unit (4) of every plaster unit.

14. The plaster system of claim 7, characterized in that the piezoelectric units are piezoelectric foils (4).

15. The plaster system of claim 7, characterized by a positioning template for pre-determined, grouped arrangement of the plaster units (13) of the system in a given geometrical structure, possibly relative to a particular tissue area.
