Abstract

1365836 Pulse generating circuits ARCO NUCLEAR CO 18 Jan 1972 [26 Jan 1971] 2373/72 Heading H3T [Also in Division A5] A heart pacemaker comprises a multivibrator having two transistors Q11, Q21 of opposite conductivity type the emitters and collectors of which are connected electrically in a series loop which is connected to a power source PIN, two resistors R41, R61 connected between the base and collector of respective ones of Q11, Q21, first series-connected resistor and capacitor R51, C11 between Q11 base and Q21 collector and second series-connected resistor and capacitor R31, C21 between Q21 base and Q11 collector, whereby said resistors, capacitors and transistors provide a multivibrator for generating electrical pulses from source P IN , resistors, R41, R61 ensuring that Q11, Q21 are quiescently unsaturated and that the multivibrator is self-starting, and R51, C11 and R31, C21 controlling the duration of each pulse generated and in co-operation with R41, R61 controlling the inter-pulse period. Transistor Q31 acts as a current amplifier and as a series current regulator. The output pulse rate may be used as an indication of the supply voltage, the pulse rate decreasing with decrease in supply voltage. The circuit of Fig. 6 may be modified to function with a lower voltage supply by the inclusion of a capacitor-transistor voltage doubler or a step-up transformer in the output circuit OS1, Figs. 7, 8 (not shown). The supply PIN may comprise a series/parallel arrangement of mercury cells or preferably a radioisotope thermoelectric generator having a plurality of thermocouple tapes connected in a series/ parallel mode for “fail-safe” redundancy.
