Control circuit of organ chip culture device and organ chip culture device

Abstract

This application provides a control circuit and an organ-on-a-chip culture device. The organ-on-a-chip culture device includes a motor, a gas guiding mechanism, and a bracket located below the gas guiding mechanism. The bracket carries a culture box containing an organ-on-a-chip. The control circuit includes a motor drive unit, an optocoupler unit, and a control unit. The motor drive unit is connected to the motor. When the motor drive unit drives the motor to operate, it can drive the transmission component to move, thereby causing the gas guiding mechanism to move up and down. The optocoupler unit is set at a first preset position. When the gas guiding mechanism abuts against the culture box, the optocoupler baffle on the transmission component is located at the first preset position. When the optocoupler baffle detects that the gas guiding mechanism abuts against the culture box, the control unit controls the gas in the gas guiding mechanism to flow into the culture box, automatically realizing the introduction of gas into the culture box, simplifying operation and reducing the risk of contamination.
