摘要： PURPOSE:To provide a blood bleeding failure detection system of a blood dialyser which is simplified in the structure and improved in reliability by eliminating the need of adjustment. CONSTITUTION:A monitoring device 40 is formed by utilizing pressure detecting means (blood chambers 24, 26, transducers 28, 30) in the conventional device. That is, the pressure Ap of the arteryside and the pressure Vp of the vein side detected by the transducers are input to an analog switch 46 through amplifier circuits 42, 44 and subsequently the output is input to a monitoring display part 52 through an A/D converter 48 and a microcomputer 50. Further, the rotational frequency R of a blood pump 16 is input to the microcomputer through a counter 54. The designated operation is conducted by the microcomputer to display an alarm signal or the like on the monitoring display part.

摘要： PURPOSE:To detect micro bubbles by splitting an output of a rectifying circuit into three parts and inputting first and second outputs to a first comparator via a delay circuit and a bias circuits respectively and inputting the third output to a second comparator as it is. CONSTITUTION:Supersonic waves passing via bubbles 14 existing in liquid 12 in a tube 10 and reaching a supersonic vibrator 18 are converted into a dc signal by a rectifying circuit 26. A dc signal output of the circuit 26 is split into three parts (a,b,e) wherein a signal (a) is input to a comparator 36 via a delay circuit 32 (delay time is set to a constant where a reference value of the comparator 36 does not fluctuate due to a change in voltage when micro bubbles 14 are sensed), a signal (b) is input to the comparator 36 via a bias circuit (for applying bias voltage slightly smaller than an amount of change in voltage fluctuating when the micro bubbles 14 are sensed), and a signal (e) is input to a comparator 28 as it is, respectively. By comparison in the comparator 36, micro bubbles of approximately 0.1 mul can be detected. Predetermined reference voltage (d) input to the comparator 28, and comparison with the signal (e) allows the detection of large bubbles which exceed a predetermined delay time.

摘要： PURPOSE:To allow the effective execution of the monitoring of the dewatering control corresponding to a change in a dewatering rate by monitoring whether continuously measured TMP values are always within a prescribed tolerance domain during the dialysis time. CONSTITUTION:The TMP value p1 at the point t1 of time when the dewatering is started by setting the dewatering rate is calculated by equation 1. Prescribed upper and lower limits are previously given with this TMP value p1 as a reference point and the 1st tolerance domain is set. The TMP value p2 is calculated at the point t2 of time when the prescribed times elapses and the 2nd tolerance domain is similarly set with the TMP value p2 as a reference point. The similar operations are thereafter repeated and the TMP values p3 to pn at the respective reference points t3 to tn of time are calculated and the tolerance domains corresponding to the respective TMP values are set. The TMP values are continuously measured from the vein pressure and dialysis liquid pressure in the dialysis apparatus constituted in such a manner and are compared and computed with the set values, by which an adequate alarming operation is executed when the measured values exceed the set values.

摘要： PURPOSE:To improve the corrosion resistance against the core by making it of a ferrite-based stainless steel containing more than 16% of chromium and more than 0.75% of molybdenum. CONSTITUTION:A dialysis liquid is fed from an inlet la and drained to an outlet 2a. When a coil 13a is excited, a moving core is attracted to a fixed core 14 to pull up valve rubbers 7 and 7a. The result of a corrosion resistance test on the fixed core 14 and the moving core 10 indicates that the use of a ferrite-based stainless steel containing more than 16% of chromium and at least more than 0.75% of molybdenum can improve the corrosion resistance against the dialysis liquid.
