For example, when air bubbles enter the blood flow path in the blood system, Artificial Kidney Devices uses an air bubble detection signal to compress the blood flow path to immediately stop blood injection into the patient's veins. It is equipped with a means for blocking the passage (referred to as a bubble locking mechanism).

This bubble opening mechanism is designed to be driven by a solenoid, but requires a large amount of torque when activated. For this reason, an excessive current flows through the solenoid for a short time. Since solenoids are often used in this way, continuous ratings and short-time ratings are determined for solenoids.

On the other hand, due to a failure in the solenoid drive circuit (power supply circuit) or the like, an overcurrent may flow through the solenoid for a long period of time, burning out the solenoid and causing a serious accident.

Therefore, the solenoid drive device must be configured to determine whether an overcurrent is caused by a short-time rating or a failure and take countermeasures when an overcurrent flows through the solenoid.

As described above, the solenoid according to the present invention is turned on and off using a switching method, which is dangerous because it generates noise. Further, since the operation of the operating end by the solenoid is reliably confirmed and the operation is performed based on the confirmation, serious accidents will not be caused by a single operation of the solenoid or the like. Furthermore, since the time lag fuse does not respond to the short-time rated current of the turenoid, but responds in the event of a true failure, the reliability of the device is high. In the above am example, the time lag fuse does not respond to the output of the rectifier circuit. However, the present invention is not limited to this, and may be provided on the AC circuit side.
