Abstract

1335761 Cardiac defibrillator PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [8 April 1970] 26174/ 71 Heading A5R A cardiac defibrillator comprises a high voltage pulse generator having at least one electrode 5, 6 for applying an electrical pulse to a patient and a device including a member for converting a mechanical pulse into an electrical pulse, the device being coupled to an externally operable control member 17 for activating the pulse generator. As in Figures 1 and 2 (not shown), the control member 17 is a button which releases a catch (20, 21) to cause a spring loaded mallet (23) to strike a pieza-electric member (24), the electric pulse from the member (24) being applied through a control 31, a relay 32, and a switch mechanism 33, 34, 35 to cause a capacitor 36 to discharge towards the patient. It is stated that the pulse generator output may be synchronized to cardiac signals sensed at the electrodes, one electrode having an indicator lamp showing the cardiac output. The mallet and piezoelectric member may be replaced by a magnet moving within a coil.
