Abstract: According to one embodiment, a memory device includes a substrate; a structure including a plurality of conductive layers stacked on the substrate; and a pillar arranged inside the structure and including a semiconductor layer that extends in a direction perpendicular to a surface of the substrate. The semiconductor layer includes a first portion on a side of an upper portion of the structure, and a second portion between the first portion and the substrate. The first portion has a thickness larger than a thickness of the second portion.

Abstract: A bottomed, tubular hollow elastic body that opens toward an outlet side of a drug solution flow path is accommodated and arranged in an accommodation part formed in a housing, and a middle protrusion is provided protruding toward an inlet side of the drug solution flow path from a center part of a bottom wall of the hollow elastic body. Insertion of a male luer causes the bottom wall of the hollow elastic body to be elastically deformed so as to enter inside a peripheral wall, increasing the volume of the drug solution flow path, which is formed between an outer surface of the hollow elastic body and an inner surface of the accommodation part. Removing the male luer and canceling the elastic deformation of the hollow elastic body causes the volume of the drug solution flow path to be reduced.

Abstract: An indwelling catheter including: a hollow catheter base having a tip and a back end, the back end being able to receive and connect a male connector; a tube provided at the tip of the catheter base; a flexible hemostasis valve installed inside the catheter base; a pusher installed at a back of the hemostasis valve; and a pusher guide installed between the pusher and the catheter base. The pusher has a hollow constitution whose taper reduces in diameter facing its tip. The pusher guide is able to restrict a position of the pusher at a first position where the pusher does not push open the hemostasis valve and a second position where the taper of the pusher is positioned inside the hemostasis valve and pushes open the hemostasis valve.

Abstract: A disposable lancing device including: a lancet housed in a housing and urged by a spring member such that a puncture member provided at a distal end of the lancet is adapted to extend out from the housing so as to carry out a puncturing operation; a locking ring disposed within the housing such that the lancet is allowed to displace in an extension direction through the locking ring; a locking protrusion provided to the lancet and adapted to be engaged by the locking ring so as to hold the lancet in a puncture-ready position located deep in the housing with the spring member being compressed; and an operating member adapted to carry out the puncturing operation by rotating the locking ring so as to disengage the locking protrusion from the locking ring and displace the lancet in the extension direction by means of the spring member.

Abstract: A liquid medicine self-administration device including a flexible reservoir, an operating member, a pushing member to move with respect to the operating member and to induce pressure deformation of the reservoir, and engaging means engages the operating member. With the operating member engaged by the engaging means, the pushing member is relatively moved to the operating member based on restoring force of a spring member to push the reservoir by the pushing member. By disengaging means moving in unison with the pushing member, the engaging means is released from an engaged state with respect to the operating member, when the pushing member has moved to a predetermined location while pushing the reservoir.

Abstract: Disclosed is a disposable blood collecting instrument that stably secures a sufficient volume of blood with a single puncture. A tip portion of a piercing body of a lancet contained within a housing projects by means of a biasing force of a spring assembly, and a surrounding area of an opening of the housing is made a transparent visible portion with a visible interior. Additionally, the disposable blood collecting instrument has been formed such that the spring assembly is contained within housing farther behind the piercing body than a position of the tip portion of the piercing body that has entered within the housing after piercing.
