Abstract
Abstract In an electric pulses generating apparatus for therapeutic applications, a piezoelectric generator is connected to electrodes. Some of the electrodes at least are placed in contact or in vicinity of a skin of a patient to be treated. A current of piezoelectric origin in caused to flow through a distribution head formed with notches.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
102 words
An electric pulse generator apparatus for therapeutic applications on a patient, comprising a body with a distribution head provided with notches and having a peripherally conductive belt, a piezoelectric generator, a plurality of electrodes connected to one pole of said generator, wherein said plurality of electrodes are respectively located in said notches at a level lower than the level of said conductive belt, and wherein said peripherally conductive belt is connected to another pole of said generator, whereby a current of piezoelectric origin is caused to flow through said notches between said plurality of electrodes and said conductive belt of said head.
Claim 2
Dependent Claim
102 words
An electric pulse generator apparatus for therapeutic applications on a patient, comprising a body with a distribution head provided with notches and having a peripherally conductive belt, a piezoelectric generator, a plurality of electrodes connected to one pole of said generator, wherein said plurality of electrodes are respectively located in said notches at a level lower than the level of said conductive belt, and wherein said peripherally conductive belt is connected to another pole of said generator, whereby a current of piezoelectric origin is caused to flow through said notches between said plurality of electrodes and said conductive belt of said head.
Claim 3
Dependent Claim
19 words
The apparatus as set forth in claim 1, wherein said notches are defined by walls in the distribution head.
Claim 4
Dependent Claim
42 words
The apparatus as set forth in claim 2, wherein said plurality of electrodes are at a level inferior than that of an upper edge of the walls, whereby sparks are produced even when said walls are in contact with a wet skin.
Claim 5
Dependent Claim
23 words
The apparatus as set forth in claim 1, wherein said belt has studs or contacts protruding into some at least of the notches.
Claim 6
Dependent Claim
29 words
The apparatus as set forth in claim 4, wherein said studs or contacts of said conductive belt have a curvature which is a function of the flow of current.
Claim 7
Dependent Claim
40 words
The apparatus as set forth in claim 1, wherein each of said notches comprises a deep portion and a shallow portion for defining a shoulder, with one of said plurality of electrodes being placed in the vicinity of said shoulder.
Claim 8
Dependent Claim
35 words
The apparatus as set forth in claim 6, wherein said belt forms a removable cover having studs or contacts which are indifferently engaged in the deep portion and in the shallow portion of said notches.
Claim 9
Dependent Claim
20 words
The apparatus set forth in claim 1, wherein said distribution head is removably mounted in said body to be interchangeable.
Claim 10
Dependent Claim
13 words
The apparatus as set forth in claim 1 wherein said notches are rectilinear.
Claim 11
Dependent Claim
13 words
The apparatus as set forth in claim 1, wherein said notches are arcuate.
Claim 12
Dependent Claim
29 words
The apparatus as set forth in claim 1, wherein said body comprises a mobile element and wherein said generator includes an actuator element operatively connected to said mobile element.
Claim 13
Dependent Claim
20 words
The apparatus as set forth in claim 11, further comprising an electromagnet, the core of which is said mobile element.
Claim 14
Dependent Claim
19 words
The apparatus as set forth in claim 11, further comprising a rotating motor operatively connected to said mobile element.
