Abstract: The present invention is characterized by including: a first member having a large diameter part and a small diameter part; a second member configured to be connected to the first member; and an element disposed between the first member and the second member, the first member having a recess on an end surface, the recess having a bottom that reaches a boundary position between the large diameter part and the small diameter part or a certain position on the side of the second member relative to the boundary position, the second member having a projection that is configured to fit into the recess with the element disposed between the recess and the projection, and having a screw hole extending to an inside of the projection to allow a screw part of the plunger to be screwed thereinto.

Abstract: A syringe is provided with a barrel having a distal end part provided with an outlet opening; a filter disposed closer to a proximal side than the outlet opening inside the barrel; and a holding member. A proximal side part disposed closer to the proximal side than the filter of the holding member has a flow path, a proximal side space into which the medicine flows through the flow path is provided on the proximal side of the filter, a distal side space into which the medicine flows from the proximal side space via the filter is provided on the distal side of the filter, and an area of the outlet opening is smaller than an area of the proximal side space, smaller than an area of the distal side space, and smaller than an area of the flow path.

Abstract: Provided is a syringe cap including a projection extending in the circumferential direction of a cap body, wherein the projection includes an apex located radially outward of the cap body from the outer circumferential surface of the cap body, a first inclined surface having a starting end located at the apex and having a terminal end located at a position on the side closer to the proximal end of the cap body than the starting end is, and a second inclined surface having a starting end located at the apex and on the outer circumferential surface of the cap body having a terminal end located at a position on the side closer to the distal end of the cap body than the starting end is, on the outer circumferential surface of the cap body, and the shortest distance from the starting end to the terminal end of the first inclined surface is smaller than the shortest distance from the starting end to the terminal end of the second inclined surface.

Abstract: A container includes a capitula to put contents into and out from the container, an inside container main body, in which a portion to accommodate the contents is formed, and an outside container main body, which is formed on an outer periphery side of the inside container main body, and surrounds the inside container main body. The inside container main body and the outside container main body are integrated at the capitula. A first side peripheral wall of the inside container main body and a second side peripheral wall of the outside container main body are attached to each other and are formed as a double accumulating portion at least at a portion of the first side peripheral wall. A lower end of the second side peripheral wall includes an extended foot portion that is extended to a location lower than a bottom of the inside container main body.

Abstract: A blood-viscosity measurement blood collection tube includes a bottomed tube provided with an opening at one end in a length direction and a bottom at the other in the length direction, and a sealing plug. The sealing plug includes a sealing part fitted in the opening of the bottomed tube in a hermetically sealed state, a cap part, and a thin connecting part. The sealing part includes a vertically penetrated insertion hole. The sealing part of the sealing plug is fitted in the opening of the bottomed tube, and an inner space of the bottomed tube is in a negative pressure state. The cap part is configured to be removed from the sealing plug by breaking the connecting part with an external force applied to the cap part, and the insertion hole is exposed at an upper surface of the sealing part when the cap part has been removed.

Abstract: A blood-viscosity measurement method uses a collection tube includes a bottomed tube having an opening at one end in a length direction and a bottom at the other end in the length direction. A sealing plug includes a sealing part fitted in the opening of the bottomed tube in a hermetically sealed state, a cap part, and a thin connecting part. The sealing part includes a vertically penetrated insertion hole and fitted in the opening of the bottomed tube. The method includes collecting blood using a negative pressure state of the inner space, applying an external force to the cap portion to break the connecting part and removing the cap part to expose the insertion hole at an upper surface of the sealing part, and obtaining blood viscosity by causing a viscosity-measurement falling body to fall from the insertion hole, and measuring a fall terminal velocity of the falling body.

Abstract: Provided is a measuring device including: a tablet measuring part that includes a plurality of housing parts that are each configured to house one tablet; a measuring-number selecting part that enables to select a measuring number of tablets by selecting a number of housing parts available for housing tablets out of the plurality of the housing parts; and a measuring-number fixing part that locks the measuring number selecting part to prevent the measuring number selected by the measuring-number selecting part from being changed.

Abstract: Mixing a low-viscosity solution and a high-viscosity solution was difficult. An object of the present invention is to provide a holder for mixed administration of at least two types of solutions for enhancing the radiation or anticancer therapeutic effect on a tumor, wherein the holder is capable of simultaneously discharging each solution at a constant ratio from respective syringes containing each solution.

Abstract: Provided is a cap including: a cap body; a protective cover; and an attaching device for attaching the protective cover and a top plate of the cap body to each other. The top plate includes: a through hole; and a top plate annular portion. The protective cover includes a cover body having a lower surface arranged away from the top plate. The attaching device includes a cover attaching portion formed into an annular shape around the through hole and projecting from the lower surface of the cover body toward the top side of the top plate annular portion or from the top side of the top plate annular portion toward the lower surface of the cover body to attach the protective cover and the top plate to each other.
