Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
69 words
- A process and device for the administration of pharmacological substances by iontophoresis characterized by comprising the application of one or several components for the injection of active liquid and the simultaneous application of an electric field in the same region, using one or more electrodes and the device regulating the flow as well as the intensity of the electric field or fields and the polarity of the same.
Claim 2
Dependent Claim
69 words
- A process and device for the administration of pharmacological substances by iontophoresis characterized by comprising the application of one or several components for the injection of active liquid and the simultaneous application of an electric field in the same region, using one or more electrodes and the device regulating the flow as well as the intensity of the electric field or fields and the polarity of the same.
Claim 3
Dependent Claim
127 words
- A process and device for the administration of pharmacological substances by iontophoresis as in claim 1, characterized in that the apparatus includes one or more programmable voltage generator modules which create an electric field which preferably is three dimensional using one or more electrodes which can be inserted into or attached to the exterior of the patient, a module for programming, preferably both simultaneously or by dosage the injection of one or more pharmacological substances by means of injection pumps and a processor which controls to a programme the movement of the substance or substances in the required region by means of the intensity and the polarity of the electric field created by the electrodes as well as controlling the flow caused by the injection pumps.
Claim 4
Dependent Claim
77 words
- A process and device for the administration of pharmacological substances by iontophoresis as in claim 2, characterized by a sequential programmable processor which controls one or more electric field generators which apply a voltage to the electrodes under a controlled form both as to voltage and polarity, these generators being capable of Direct current operation or changing poarity at different frequencies and to dosification units acting on the injection pumps despatching fluid to the active electrodes.
Claim 5
Dependent Claim
78 words
- A process and device for the administration of pharmacological substances by iontophoresis as in claims 1 and 2, characterized in that at least one of the active electrodes must be insertable such that it only makes electrical contact with the patient in the zone in which it is required to act, the rest being covered in an insulating material and for preference there being an electrode which does not require to be electrically live , in platinum.
