Claims

[Scope of utility model registration request]

During hemodialysis, the dialysate is supplied to the dialyzer and the waste fluid is discharged using a double metering pump of the same capacity, and the ultrafiltration needle inside the dialyzer is used to collect a predetermined amount in an ultrafiltration measurement tank. In a dialysis machine equipped with a measuring mechanism, the ultrafiltration measurement tank is made of transparent material such as glass or plastic.
A liquid level detection element for detecting a liquid level corresponding to a predetermined amount of the stored liquid and an optical blood leakage detection element are integrally installed in the measuring tank, and are connected to the liquid level detection element to detect the signal. a liquid level detection circuit that outputs a liquid level detection signal for each predetermined amount of stored liquid in response to the signal, and a leakage detection circuit that is connected to the blood leakage detection element and receives the signal, determines whether there is blood leakage, and outputs a blood leakage detection signal. a blood detection circuit;
means for receiving a liquid level detection signal from a liquid level detection circuit and discharging a predetermined amount of liquid stored in the measuring tank; and receiving a liquid level detection signal and transmitting an output signal from the blood leakage detection circuit for a certain period of time to an alarm mechanism. Blood leak monitoring device for hemodialysis with a timer.
