    摘要： A method for modifying a pump of a ventricular assist device includes the step of modifying pressure-flow characteristics of a pump of a ventricular assist device to simulate different pressure-flow characteristics or to make the flow rate of the pump more responsive to changes in the pressure differential of the pump. The step of modifying the pressure-flow characteristics of the pump may includes one or both of the steps of (1) estimating a flow rate of the pump from the speed of an electric motor of the ventricular assist device and from the current or power consumption of the electric motor, wherein the electric motor drives the pump, and (2) adjusting the speed of the electric motor as a function of the estimated flow rate of the pump and a set speed of the electric motor to simulate the different pressure-flow characteristics or to make the flow rate of the pump more responsive to changes in the pressure differential of the pump.

    摘要： The present invention provides a forming method capable of inexpensively forming a bodily fluid purification cassette which is reduced in size as small as possible. A bodily fluid purification cassette (U1) is detachably attached to a bodily fluid purification apparatus body. The bodily fluid purification cassette (U1) includes a synthetic resin box-like body (F1, F2); a basic element (R1, 1, PT1) incorporated in the box-like body; a selective element (2) selected from a bodily fluid purification element such as a dialyzer (2), a plasma exchange module and an immunoadsorbent cylinder; and bodily fluid flow passages (R1 to R7) which connects the basic element and the selective element with each other. The box-like body (F1, F2) and the bodily fluid flow passages (R1 to R7) are formed by primary molding such that a cross section of a split-type structure has a predetermined shape, and the split-type structure is integrally formed into a cassette by secondary molding. When the bodily fluid flow passages of the split-type structure are integrally formed by secondary molding, the basic element (R1, 1, PT1) and the selective element (2) are liquid-tightly connected to the bodily fluid flow passages (R1 to R7).
