High voltage generation circuit, puncture device, and blood test device |
摘要 |
A high voltage generation circuit for laser puncture in which the voltage for laser puncture can be boosted up to the laser oscillation level in a short time with low power loss. The high voltage generation circuit drives a laser unit for puncturing the skin by oscillating laser light. In the high voltage generation circuit, a capacitor is charged to supply power to the laser unit. A booster circuit supplies a current to the capacitor, and a voltage measurer measures the voltage of the capacitor. A controller controls the booster circuit based on an instruction from a user or the voltage of the capacitor to start precharge of the capacitor with a first current value at a first timing, and to start main charging of the capacitor with a second current value higher than the first current value at a second timing, later than the first timing. |
