DEVICE FOR GENERATING AN ELECTRICAL VOLTAGE OF PREDETERMINED WAVEFORM, IONTOPHORESIS APPARATUS FOR TRANSDERMALLY ADMINISTERING MEDICINAL PRODUCTS AND ELECTRICAL STIMULATION APPARATUS, WHICH APPARATUSES ARE EQUIPPED WITH SUCH A DEVICE |
摘要 |
The device comprises a switched mode power supply (1) equipped with an electronic switching element (T1), the closing of which supplies an inductor (L1) which discharges, on reopening the element, into a capacitor (C1) across whose terminals the output voltage of the device appears, characterised in that it comprises (a) memory means for recording a series of numbers reflecting successive segments of the predetermined waveform, (b) a clocked digital counter (2), and (c) means (3) for successively loading this counter (2) with each of the numbers of the series as a bound for the counting effected by the counter (2), the latter cyclically closing the switching unit (T1) for a predetermined time interval whenever the counting effected attains the bound thus fixed. <IMAGE> |
