Abstract: An atherectomy device has a drive circuit which rotates a direct-current motor. The drive circuit has a three-terminal regulator having an ADJ terminal. A partial pressure resistor is connected between the ADJ terminal and an output terminal of the three-terminal regulator. Moreover, one end of six variable resistors whose resistances are set to be different from each other is connected to the ADJ terminal. The other end of the six variable resistors is selectively connected to the negative electrode of a battery by a change-over switch which is a rotary switch having six contacts. When the variable resistors are switched by the change-over switch, the output current of the three-terminal regulator becomes large. Thus, the rotation speed of a cutter which is rotated by the direct-current motor becomes high.

Abstract: An objective of the present invention is to provide an indwelling needle assembly that has a novel structure and improves operability for the practitioner. An indwelling needle assembly 10 in which an inner needle unit 16 comprises a storage housing 14 for storing a protector 52, and which is provided with a connecting member 94 that connects the storage housing 14 to an outer needle hub 20. The protector 52 prevents movement of the connecting member 94 and holds the storage housing 14 and the outer needle hub 20 in a connected state. Deformation or displacement of the protector 52 due to retraction of an inner needle 12 permits the movement of the connecting member 94 and makes it possible to release the connected state between the storage housing 14 and the outer needle hub 20.

Abstract: A hollow fiber porous membrane includes polyethersulfone or polysulfone. The hollow fiber porous membrane has an inner diameter from 300-600 μm, a thickness from 70-200 μm, a molecular weight cut-off of 10000 or lower, and a plurality of pores having a pore diameter from 0.1-0.5 μm throughout an outer surface; and a bulging rate of less than 5%. For 20 or more of the hollow fiber porous membranes, after a membrane thickness in a cross section of each one of the hollow fiber porous membranes in the width direction is measured at randomly selected 10 or more locations, an average membrane thickness is calculated based on 200 or more locations in total, and the bulging rate is calculated by a formula below: Bulging Rate (%)=(location numbers where the membrane thickness as measured exceeded 1.3 times the average membrane thickness)/(membrane thickness measurement numbers)×100.

Abstract: Provided is a novel manufacturing method for a conical hollow needle that makes it possible to efficiently form a conical part that has a nearly perfectly circular outer circumferential surface shape. The present invention is a method of manufacturing a conical hollow needle that has a conical part that has a tapered outer circumferential surface. The manufacturing method involves immersing a hollow needle having a straight shape in an electrolyte solution to conically electropolish an outer circumferential surface. From a start to an end of the electropolishing, the hollow needle, which serves as an anode, is sandwiched between a pair of cathodes at a prescribed distance therefrom in a radial direction, and the hollow needle is rotated around a needle axis thereof to change which faces of the hollow needle are opposite to the cathodes.

Abstract: A coupler comprises a syringe attachment part to which a syringe including a nozzle part having a lock collar is detachably attached; a vial attachment part to which a vial is attached; and a double-ended needle for placing the syringe and the vial in communication. In the coupler, a cap which covers the nozzle part of the syringe is attached to a cap holder having an engaging part for engagement with the lock collar; a holding mechanism is provided which holds an engaged state of the engaging part with the lock collar; and a release mechanism is provided which releases holding of the engaged state of the engaging part with the lock collar in the holding mechanism due to the syringe and the vial being moved relatively closer to each other to be placed in communication by the double-ended needle.

Abstract: A sprayer includes a barrel, a finger grip, a gasket, a rod, and a plunger slidably attached to the rod and capable of contacting the rod and pressing the rod toward a distal side. The plunger includes a contact member which is brought into contact with the finger grip, and a first pressing surface provided at a proximal end thereof. The rod includes a second pressing surface provided at a proximal end thereof. The contact member is brought into contact with the finger grip to restrict the movement of the plunger toward the distal side with the gasket positioned between a distal end and a proximal end of the barrel.
