Abstract: To provide a container for a medical device, which enables easy removal of wrapping, thereby significantly reducing the labor for unpacking at the delivery destination such as a pharmaceutical company or a medical institution. Furthermore, the provided container for the medical device enables easy removal of wrapping even during an automated process in a filling machine for medical solutions, for example. In this container for a medical device, a holder holding at least one medical device is placed inside a container body having an opening at the top, and the opening is sealed with a gas-impermeable film. When sterilizing the exterior of the container using a sterilization gas, the sterilization gas does not permeate into the container due to the gas-impermeable film, so the medical device and the holder thereof placed inside the container are never exposed to the gas.

Abstract: A container for receiving or storing or carrying pistons for injectors, the container having a base plate and hollow cylindrical piston storage parts (the container being hereafter referred to as a piston nest). Each of the hollow cylindrical piston receiving parts is formed either by making it vertically penetrate through the basic plate, with one side of the base plate functioning as one opening end, and project from the other side or by making it vertically penetrate through the base plate and project from both sides of the base plate. Preferably, each piston receiving part has a swelled part where a part of the inner peripheral wall surface of the piston receiving part is swelled inward. The pistons for injectors are received in the piston receiving parts.

Abstract: Disclosed is a plunger rod for a syringe. The plunger rod is useful for sliding a piston within a syringe barrel. The plunger rod is characterized in that it is colored in part or in whole. The syringe is also disclosed. According to such plunger rods, even plural syringes of exactly the same external appearance and configuration can be applied with features that make it possible to readily and visually identify them by simply taking a glance at their appearances without needing a measure such as applying indication members such as labels on them. Further, the use of such plunger rods makes it possible to provide syringes of significantly enhanced visual identifiability without impairing high-level quality, functions, sanitariness and safety required for the syringes.

Abstract: A plastic-made cap for a vial having a lip, the cap being useful as a separation-preventing cap for a plug that seals up an opening of the vial, includes a top wall portion having an outer circumference and centrally defining an opening, and a cylindrical skirt portion extending downwardly from the outer circumference of the top wall portion and being open at its lower end. The skirt portion has an inner diameter (a) greater than an outer diameter (b) of the lip of the vial. The skirt portion is provided on its inner wall with plural ribs formed in a direction perpendicular to the top wall portion. The plural ribs are arranged in pairs at equal angular intervals between the respective pairs of ribs. Further, engagement claws are arranged between the respective pairs of ribs such that the engagement claws can be brought into engagement with an underside of the lip of the vial.

A needle-equipped syringe barrel 1 in which a metal needle 12 is integrally equipped to a synthetic resin syringe nozzle 113 by integral molding, height of a needle end 122 extruded toward an inner hollow portion thereof opposite to a needle head 121 being in a range of 0.4 to 11 mm.

Abstract: Provided is an easy-to-handle prefilled type nasal drip appliance which can spray medical solution surely into the nostril while holding down the production cost. A syringe barrel has a spray hole and a latching portion of a center stopper on one side, with a conduction portion of medical solution being provided at the latching portion, and has a portion protruding inward of the inner circumferential surface formed on the other end side. A plunger has a portion protruding outward of the outer circumferential surface formed substantially in the axial center wherein both protrusions engage with each other. When the plunger is moved in the spray direction of the syringe barrel to get over the plunger side protrusion and disengaged, the medical solution moves the center stopper in the spray direction to form a medical solution inflow groove between the conduction portion formed at the center stopper latching portion and the center stopper.

Abstract: A plunger rod useful for sliding a piston inserted in a syringe barrel has a threaded portion formed at an end of the plunger rod to attach the piston on the plunger rod and a flange formed at an opposite end of the plunger rod. The threaded portion and the flange are integrally connected together by a cylindrical member having an outer diameter such that the cylindrical member can be inserted with contact slidability in the syringe barrel, for example, an outer diameter equal to or slightly smaller than an inner diameter of the syringe barrel.

Abstract: A vacuum packaging system for transporting a plurality of medical containers includes a plurality of medical a tray that receives and supports the medical containers. The tray includes opposing first and second side walls, opposing side and rear walls and a bottom floor. The walls extend generally perpendicularly from the bottom floor of the tray to a top edge thereof. A nesting plate is removably mountable in the tray and includes a plurality of generally cylindrical sleeves each receiving one of the plurality of medical containers. A support surface within the tray generally extends parallel to and spaced a predetermined distance from the bottom floor of the tray and receives and supports the nesting plate. An air impervious flexible film defines an internal cavity and completely surrounds the tray and the medical containers. The internal cavity is evacuated to and maintained at a predetermined vacuum level below atmospheric pressure.

Abstract: A syringe mold with a coolant circulation outward and homeward positioned close to the cavity space and a sufficient coolant circulating flow for cooling a core cylinder is provided. Slide cores (5, 5) are put in the position where the slide cores (5, 5) protrude from the circumference of the core cylinder (2) by moving the slide core operating jig (4) forward in the axial direction of the core cylinder (2) while cooling the core cylinder (2) by the coolant. Then, a two medical agent mixing type syringe having a communicating groove on the inner circumference for mixing two medical agents is injection-molded. A molding failure due to insufficient cooling of the core cylinder (2) can be prevented by positioning the coolant outward and homeward close to the cavity space and making the cross sectional area of the coolant outward and homeward enough large because the coolant outward and homeward is partitioned by the circumference of the jig container space in the core cylinder (2).
