    Abstract: To provide a blood treatment filter device capable of efficiently utilizing a blood treatment filter.A blood treatment filter device 20 has a filter sheet 26 through which a specific component among components forming blood is harder to pass than other components and a spacer sheet 27 through which the specific component is easier to pass than through the filter sheet 26. The filter sheet 26 has filter through-holes 39 disposed at intervals. The filter sheet 26 and the spacer sheet 27 are spirally wound in an overlapped state. The filter device 20 has seals 31 sealing both end portions in the longitudinal direction of a wound body 25 formed by the filter sheet 26 and the spacer sheet 27 which are spirally wound in a fluid-tight manner. The outer peripheral surface of the wound body 25 is formed by the filter sheet 26.

    Abstract: In an indwelling needle assembly, a safety mechanism part is provided with an outer-needle-hub engaging part to be engaged with an outer needle hub, and an engaging-part opposing wall. Relative rotation of the outer-needle-hub engaging part and the engaging-part opposing wall is restricted, and at least one of the outer-needle-hub engaging part and the engaging-part opposing wall displaces integrally with urging parts. When an inner needle is pulled out of the outer needle hub, a block part engaged with the inner needle through an inner-needle engaging part is moved relative to the urging parts and forced to a non-contact state, and the urging parts displace in a direction approaching the inner needle, thereby preventing a needle tip of the inner needle from protruding from the safety mechanism part and releasing engagement of the outer needle hub with the safety mechanism part.

    Abstract: A blood circuit having a pressure measurement portion connected to a pressure measurement device includes: a first measurement portion provided downstream of a pumping segment; and a second measurement portion provided upstream of the pumping segment. The first measurement portion includes: a first housing having a tubular shape; and a first flexible membrane having a tubular shape and provided in the first housing. The second measurement portion includes: a second housing having a tubular shape; and a second flexible membrane having a tubular shape and provided in the second housing. A space between the first flexible membrane and the first housing is larger than a space between the second flexible membrane and the second housing in an initial state before permitting the blood to flow.

    Abstract: This invention provides a PTP sheet for pharmaceutical drug packaging from which a solid pharmaceutical drug is easily taken out and in which a pocket portion is hard to be accidentally damaged. A PTP sheet has a first sheet from which a pocket portion capable of housing a solid pharmaceutical drug protrudes to the side of an upper surface and a second sheet which is stuck to a lower surface of the first sheet and which closes an opening of the pocket portion. The pocket portion has a peripheral wall portion having a peripheral surface continuous with the upper surface and a top portion having a top surface continuous with the peripheral surface of the peripheral wall portion. A wall thickness of the peripheral wall portion is smaller than a wall thickness of the top portion.

    Abstract: A filter device has a catheter having a lumen, a shaft extended in the longitudinal direction from the lumen, and a filter capturing an embolus. The filter is connected to the shaft through a slide ring at the distal end thereof. The shaft is inserted into and passed through the ring. The ring is rotatable with respect to the shaft and slidable in the longitudinal direction. When the filter is expanded in a blood vessel, the ring slides on the shaft. The filter is connected to the shaft through another ring on the peripheral edge of an opening. The shaft is inserted into and passed through the ring. The ring is rotatable with respect to the shaft. The ring is held between a pair of stoppers fixed onto the shaft. Therefore, the movement of the ring in the longitudinal direction with respect to the shaft is prevented.

    Abstract: A fluid concentration measuring device measures the concentration of a fluid flowing through a duct having a light-transmissive, deformable duct wall. The device includes a light source; a light receiving element which receives the light, which passed through the wall of the duct and the fluid inside the duct, and outputs a signal indicating the intensity of the light; light path distance setting means and fluid concentration output means which obtains a plurality of relational expressions, which indicate the relation between the light intensity and the fluid concentration when the light from the light supply part is received by the light receiving part over each of the light path distances, and obtains the fluid concentration from the light intensity at the light receiving part based on the relational expressions for the plurality of light path distances and outputs the fluid concentration.
