    摘要： A system for priming an extracorporeal blood circuit is described. The system includes a fluid circuit with an air venting mechanism, a reversible pump, arterial and venous lines, a prime waste bag and a switchable coupler selectively connecting the arterial and venous lines to the waste bag or alternatively interconnecting the arterial and venous lines. A priming fluid is connected to the circuit and circulated in the circuit under different configurations of the arterial and venous line connections.

    摘要： A dialysis system which does not need to use a physiological saline in replenishing a solution or cleaning and priming the dialysis system, does not need a troublesome setting operation and can easily and accurately set a flow rate of a replenisher solution. The dialysis system includes a closed-type water-removal control apparatus 1, a dialyzer 2, a fresh dialysate line 3 as well as a used dialysate line 4, an RO water pressurizing line 5, an RO water pressurizing pump 51 provided in the RO water pressurizing line 5, an artery side blood line 6, a blood pump 61 provided at the artery side blood line 6 and a vein side blood line 7. According to the dialysis system, by pressurizing RO water into a communication line of the used dialysate, dialysate is made to flow from a dialysate flow path 21 into a blood flow path 22 through a dialysis membrane 23 of the dialyzer 2 and the inside of a blood circulation path can be cleaned and primed.

    摘要： A method for withdrawing priming fluid from the extracorporeal circuit of a dialysis machine is described which substantially prevents return of the priming fluid back to the patient. In accordance with the method, priming fluid is drawn from the extracorporeal circuit through the dialyzer membrane and into the dialysate circuit. Blood is introduced into the extracorporeal circuit as the priming fluid is withdrawn through the dialyzer. Withdrawal of the priming fluid may be accomplished by pumping the blood pump in the forward direction at a first rate and operating a pump in the dialysate circuit at a second rate. Valves in the dialysate circuit are operated such that the pump in the dialysate circuit draws priming fluid across the dialyzer membrane into the dialysate circuit, and thereby prevents the priming fluid from being returned to the patient. In a preferred embodiment, the fluid volumes of the arterial and venous portions of the extracorporeal circuit, and the fluid volume of the blood side of the dialyzer, are known in advance. With this information, it is possible to operate the blood and dialysate pumps such that the blood progresses into the arterial and venous lines at different rates such that blood reaches the dialyzer via both lines at about the same time, while at the same time the priming fluid is withdrawn through the dialyzer. Thus, in this embodiment, blood fills the extracorporeal circuit after priming with only a small amount of priming fluid remaining in the blood compartment of the dialyzer being returned to the patient.

    摘要翻译： 描述了一种用于从透析机的体外回路抽出引发液的方法，其基本上防止引发流体返回到患者体内。 根据该方法，将引发流体从体外循环通过透析器膜吸入透析液回路中。 当引流液通过透析器取出时，将血液引入体外循环。 起动流体的抽出可以通过以第一速率以正向方向泵送血泵并以第二速率操作透析液回路中的泵来实现。 操作透析液回路中的阀，使得透析液回路中的泵将启动流体穿过透析器膜吸入透析液回路中，从而防止引发液体返回到患者体内。 在优选实施例中，体外循环的动脉和静脉部分的流体体积以及透析器的血液侧的流体体积是预先已知的。 利用该信息，可以操作血液和透析泵，使得血液以不同的速率进入动脉和静脉线，使得血液在同一时间经由两条线路到达透析器，同时启动 流体通过透析器取出。 因此，在本实施例中，仅在少量的剩余在透析器的血液室中的引发液体返回给患者之后，血液填充体外循环。
