Title:
SPHYGMOMANOMETER AND PUMP DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/157394
Kind Code:
A1
Abstract:
A pump driving system (320) according to the present invention comprises a booster (62) that boosts DC voltage (V1) from a power source (53) and outputs the voltage as DC voltage (V2), and an H-bridge portion (63) that has first and second series circuits respectively including two switching elements connected in series between a high potential and a reference potential corresponding to the DC voltage (V2). The two switching elements of the first series circuit and the two switching elements of the second series circuit are respectively turned on and off by a control signal (CTL2) from a control unit (100). A voltage (Vout) that is generated between a first connection point between the two switching elements of the first series circuit and a second connection point between the two switching elements of the second series circuit is a driving voltage used to drive a pump (32).
