Abstract: A medical syringe, having a syringe barrel, a piston, a plunger rod, and a plunger rod holder, wherein a barrel main body of the syringe barrel is formed to have a small inner diameter part and a large inner diameter part, the piston is formed such that the circular part is comprised of an elastic material and has an outer diameter larger than the inner diameter of the small inner diameter part of the barrel main body so that the outer periphery of the circular part can be brought into contact with the inner peripheral surface of the small inner diameter part by pressurizing, and the piston can be held in the large inner diameter part of the barrel main body in a state of being freely fitted thereto.

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.

Abstract: The present invention provides a medical container: that is configured of an upper member and a lower member; that can be molded by injection molding; that has an excellent dimensional accuracy; and in addition to these, that is capable of effectively preventing the trouble that a molten resin for joining the upper member and the lower member enters the container. The present invention is a bottomed tubular medical container 1 made of a resin and continuously configured of a neck 12, a shoulder 14, and a body 16.

Abstract: This invention has as its object to allow an authentication process that avoids unnecessary information from being stored in a digital camera irrespective of whether or not a digital camera connected to the printer has a direct print function. To this end, in this invention, in an early stage of connection between a digital camera DSC and PD printer, the PD printer side requests an object which contains a keyword as authentication information of those which are stored and held by the DSC (S29). As a result, after it is determined the returned information contains authentication information, the printer notifies the DSC of its own authentication information (S33).

Abstract: A medicine syringe has a syringe barrel, piston and plunger rod. The syringe barrel is provided with a cylindrical main body defining therein a chamber to be filled with a medical solution, and an injection nozzle portion formed at an end portion of the main body and defining therein a hollow bore in communication with the chamber. The chamber and hollow bore have a total capacity of not greater than 0.5 mL. The chamber and hollow bore are formed such that the piston is slidable in a range of from 20 to 100 mm and is allowed to slide liquid-tight into the hollow bore beyond the chamber.

Abstract: A syringe kit for mixing two medicinal fluids includes first and second barrels containing medicinal fluids therein. The first barrel includes a connecting tube portion at a tip portion having a male screw on an outer periphery, and a non-roughened inner tapered surface on an inner periphery. The second barrel includes a second plunger, a screw tube portion with a female screw on an inner periphery thereof freely engageable with the male screw of the connecting tube portion, and a nozzle portion situated inside the screw tube portion with a non-roughened outer tapered surface fitting to the non-roughened inner tapered surface. A surface of the male screw and the outer periphery of the connecting tube portion, or a surface of the female screw and the inner periphery of the screw tube portion are roughened to a surface roughness in a range between Ra 1.0 and Ra 2.0 micrometer.
