Ultra-sonic Generator Circuit for Deposit Prevention in Syringe Pump and Ultra-sonic Generator Having the Same

摘要

Disclosed is an ultrasonic generator for suppressing the generation of precipitates in a syringe of a syringe pump device, and an ultrasonic generator including the same. The ultrasonic generator 100 according to the embodiment of the present invention includes a first switching element 110 having one end connected to a power source and the other end connected to the ultrasonic output unit 160 through the protection circuit unit 130; A second switching element 120 having one end connected to the ground and the other end connected to the ultrasonic output unit 160 through the protection circuit unit 130; A protection circuit unit 130 connected between the first switching device 110 and the second switching device 120 and directly connected to the ultrasonic output unit 160; A current mirror unit 140 directly connected to the control unit 150 and allowing the same output current to flow through the first switching device 110 and the second switching device 120 according to an input signal input from the control unit 150; And the like. According to the present invention, there is an effect that the ultrasonic generator can be configured with a simplified structure compared to the structure of the ultrasonic generator according to the related art.
