Abstract: A heat exchange module 12 is formed by stacking pipe groups obtained by fixing a plurality of pipes 1 with use of pipe array holding members 9a to 9d. Flow path forming members 50 are arranged on pipe groups in the uppermost and lowermost layers, and walls 51 and 52 are provided so as to protrude from the outer-side pipe array holding members and the inner-side pipe array holding members. Flow path members 63 are provided between the walls 51 and 52 adjacent to each other so as to allow through holes 53 and 54 to communicate with each other. The heat exchange module 12 is housed in the housing 2, and while rotating the housing 2, a resin material 24 is filled into a space enclosed by the two inner-side pipe array holding members of each pipe group in the housing 2, interstices around the pipes present between an opening 15a of the housing and the outer-side pipe array holding members, and interstices around the pipes present between an opening 15b of the housing and the outer-side pipe array holding members.

Abstract: A conduit tube (90) that communicates with an intracardiac blood inflow port (50) and a liquid medicine injection port (72) and allows blood from the intracardiac blood inflow port and a liquid medicine from the liquid medicine injection port to flow into a cardiotomy section (2) is inserted from above downward in the cardiotomy section 2. A blood flow channel (93) for the flow of blood and a liquid medicine flow channel (95) for the flow of a liquid medicine are formed independently of each other in the conduit tube. With respect to the vertical direction, the lower end of a blood conduit tube portion (94) that forms the blood flow channel is located at a lower position than the lower end of a liquid medicine conduit tube portion (96) that forms the liquid medicine flow channel. This prevents the generation of negative pressure in the liquid medicine flow channel due to the flow of blood. It also reduces the resistance to the inflow of a liquid medicine into the cardiotomy section.

A first check valve (21) that functions to permit the flow of drug solution toward the cavity from the drug solution flow path and restrict the flow of drug solution in the opposite direction is provided on a flow path between a drug solution flow path (31) of the cylindrical body and the cavity. A second check valve (22) that functions to permit the flow of drug solution toward the connector from the cavity and restrict the flow of drug solution in the opposite direction is provided on a flow path between the connector and the cavity. Drawing a plunger (45) of the syringe in and out enables a drug solution (72) contained in the drug solution container to be efficiently transferred to the infusion bag.

Abstract: A medical container (1) includes a bag-like container body (10) made up of two flexible sheets (12a, 12b). At least one of a pair of long-side sealed areas (11La, 11Lb) formed by the two sheets being bonded together is provided with a sealed protruding portion (20a, 21a, 20b, 21b) protruding toward the other long-side sealed area such that the spacing between the pair of long-side sealed areas is locally narrowed. A crease (30a, 31a, 30b, 31b) passing through the sealed protruding portion is formed in the sheets when a liquid substance has been injected into the container body in a volume greater than or equal to 10% of a defined volume of the container body and the medical container is hung. Accordingly, it is possible to know the exact amount of a liquid substance in the container by using a scale provided on the sheets constituting the container even if a crease is formed in the sheets due to the liquid substance being in the container.

Abstract: A peritoneal function testing apparatus tests the peritoneal function of a dialysis patient easily and with high accuracy. Standards of four kinetic parameters (CCr, Kt/V, MTACu, and MTACc) available in a definite dialysis guideline are computed in accordance with a relational expression, and a curve showing the relation between MTACu/c and the drained fluid volume is indicated in a graph together with the PET data of the patient which has been prepared separately. Thus, the peritoneal function can be evaluated based on the relative position of the patient's data and the curve showing the standard values in the graph.

Abstract: A process for producing a porous body with different physical properties in desired regions is provided by pore forming treatment, not by bonding two or more materials made porous beforehand, with, for example, an adhesive. Raw materials are prepared, each of which contains a polymer and a raw material preparation solvent. At least two types of the raw materials having different compositions are prepared. Thereafter, the respective raw materials are frozen into desired shapes to form frozen bodies thereof. The frozen bodies thus formed are brought into contact with each other to form an assembly thereof, the assembly is exposed to a condition under which the frozen bodies begin to melt, and the assembly is then freeze-dried. Thus, a porous body having regions different in physical properties can be obtained. Such a porous body can be used as, for example, an adhesion inhibitory material or a scaffold for a cell culture.

Abstract: A hemodialysis apparatus includes a blood processing machine, a blood circuit through which blood led from a patient flows, a blood pump attached to the blood circuit to pump blood, a dialysate circuit, a clamp disposed downstream of the blood pump for the blood circuit to block the blood circuit, a blood pressure sensor for detecting the pressure of a part of the blood circuit between the blood pump and the blocker, and a control unit connected with the blood pump and the blood pressure sensor. The control unit is configured to determine, based on the pressure detected by the blood circuit pressure detector, whether or not the blood circuit has encountered abnormal conditions while the blood circuit blocked by the clamp is filled with liquid by the blood pump (steps SA2, SA3, and SA5).

Abstract: The present invention provides a porous member formed not by the paste method and a method of producing the porous member. The porous member of the present invention includes a core layer and a porous surface layer, wherein the core layer and the surface layer are composed of the same polymer raw material, the surface layer is formed integrally on a surface of the core layer, and the porous member does not comprise an adhesive layer between the core layer and the surface layer. Such a porous member can be produced by making the surface of a polymer substrate porous. Specifically, the porous member can be produced by immersing the polymer substrate in a solvent capable of dissolving the polymer substrate and freeze-drying the immersed polymer substrate.

A stopper section is provided only on one side of the boundary between the tube lead-in section and the slit section.

Abstract: A state detecting device can efficiently remove air bubbles from a liquid no matter whether the liquid flows forwards or backwards. The state detecting device (1) is provided in a tube to detect a state of a liquid flowing in the tube. The state detecting device (1) includes: a liquid hold part (2) in which the liquid is stored; an inflow part (4) from which the liquid enters the liquid hold part (2); an outflow part (5) from which the liquid exits from the liquid hold part (2); an inlet (8) that is a rear end portion of the inflow part (4); and an outlet (9) that is a front end portion of the outflow part (5). Here, the inlet (8) and the outlet (9) are arranged higher than a center of the liquid hold part (2) in a vertical direction when the state detecting device is provided in the tube.

Abstract: An inner hub (9) with a needle attached to a tip thereof is housed in a cylindrical body (2). The inner hub (9) includes a through-hole (22) penetrating the inner hub (9) in a radial direction of the inner hub (9), and a recessed portion (23a) formed in an outer circumferential surface (23) of the inner hub (9). An opening of the through-hole (22) and the recessed portion (23a) are connected together in a circumferential direction of the inner hub (9). A liquid flowing out from the opening of the through-hole (22) is limited so that the liquid flows along the recessed portion (23a), and the flow of the liquid moving in the circumferential direction of the inner hub (9) is promoted. As a result, the removal of air bubbles in the circumferential direction of the inner hub (9) is promoted, whereby air bubbles can be prevented from remaining on the outer circumferential surface (23) of the inner hub (9).
