A injection-needle cover includes an injection needle enclosure portion, which has paired base-side wall portions, a cylinder portion, paired tip-end-side wall portions, an injection needle contact portion, a hook portion, and a needle tip end fixing portion. The injection needle contact portion is disposed at a position in a base-side axial space, which is a boundary between the base-side axial space and an intra-cylinder space. The injection needle contact portion has a force receiving portion and a connecting portion. The force receiving portion receives a force from the injection needle when the force receiving portion comes in contact with the injection needle. The force receiving portion has an easy sliding portion, which is disposed in an area adjacent to an injection needle, and slides more easily along the injection needle than a case where an edge slides along the injection needle.

Injection-needle cover

In a method for hydraulic transfer printing, comprising floating a transfer sheet comprising a polyvinyl alcohol polymer film and a print layer formed thereon on a surface of an aqueous solution while directing the print layer upward, and then pressing an article against the surface of the aqueous solution to transfer the print layer to the article, wherein the surface tension of the aqueous solution is adjust to 45 mN/m or less and the extension ratio of the transfer sheet is adjusted to 1.30 or less during the transfer. This makes it possible to transfer a high-definition print pattern to the surface of an article having irregularities or a curved surface.

Method of hydraulic transfer and hydraulic transfer base film

A two-compartment type prefilled syringe includes a first rubber stopper fitted into a front sleeve, a second rubber stopper fitted into a rear end portion of a cartridge, a third rubber stopper for hermetically dividing the interior of the cartridge into front and rear compartments and a bypass formed by radially outwardly bulging a portion of a peripheral wall of the cartridge. In an axial direction of the cartridge, a length of the third rubber stopper is slightly smaller than an inner length of the bypass. When the third rubber stopper has been displaced into the bypass, the sealing property of the rear compartment with the front compartment is cancelled such that the dissolving agent, suspension or the like in the rear compartment is carried, via the bypass, into the front compartment containing dry medicament or the like. A ratio of a maximum width of one end of the bypass adjacent to the front sleeve to a maximum width of the other end of the bypass adjacent to the rear end portion of the cartridge is set to range from 1.2 to 5.0.

Two-compartment type prefilled syringe

Behind a slidable end sealing member 3c, there is provided a liquid-absorbing element M which has a liquid-holding function so as to absorb and hold a liquid L flowing out from the end sealing member 3c when the end sealing member passes over a bypass portion 6. As this liquid-absorbent element M, such as a disk-like element D and a cylindrical element R, are typically impregnated with a water-holding and liquid-absorbing accelerator to enhance a leak preventing effect and with an antimicrobial active agent to enhance hygiene.

Mixing syringe

A prefilled syringe capable of separate storage of different substances before use. It includes a tubular body having an injection needle at one end and a plunger at the other end, and a partition axially slidable in the tubular body. The partition includes a front part and a rear part independent of each other, and as a whole divides the interior space of the tubular body into a front compartment and a rear compartment in a sealing manner for storing mutually different substances. A bypass is disposed generally between the front and rear compartments to introduce the substance in the rear compartment into the front compartment when the partition is slid under pressure provided by the plunger to be adjacent to the bypass to thereby mix the substances immediately prior to injection.

Prefilled syringe

A prefilled syringe capable of separate storage of different substances before use. It includes a tubular body having an injection needle at one end and a plunger at the other end, and a partition slidable axially in the tubular body. The partition includes a front part and a rear part independent of each other, and as a whole dividing the interior space of the tubular body into a front compartment and a rear compartment in a sealing manner for storing mutually different substances. A bypass is disposed generally between the front and rear compartments to introduce the substance in the rear compartment into the front compartment when the partition is slid under pressure provided by the plunger to be adjacent to the bypass to thereby mix the substances immediately prior to injection.

A syringe has a tubular body provided at its front end portion with a portion for mounting an injection needle thereon and opens at its rear end portion so as to have a rear end opening. A gasket for sealing the rear end opening of the tubular body is slidably inserted into the tubular body. A plunger rod is detachably coupled with a rear end portion of the gasket through the rear end opening of the tubular body. A male screw is formed at a front end portion of the plunger rod and is circumferentially alternately divided into at least one male screw portion and at least one first recess portion. A female screw is formed on a rear end face of the gasket and is circumferentially alternately divided into at least one female screw portion and at least one second recess portion. A state where the male screw portion and the first recess portion of the male screw are, respectively, fitted into the second recess portion and the female screw portion of the female screw, the male screw is rotated relative to the female screw so as to be brought into engagement with the female screw such that the plunger rod is coupled with the gasket.

Syringe

An air and liquid-tight container is capable of storing different substances in different compartments sealingly separated by a front gasket having two separate parts that are independently slidable. A rear gasket is connectable to a push rod so as to function as a plunger, the front gasket being slidable in response to sliding of the rear gasket, thereby enabling the substance in the rear compartment to be introduced into the front compartment through a bypass. The front and rear gaskets are encased in the tubular body at a compressibility C (%) of 2% to 10%, with the product of the compressibility and the contact area (mm.sup.2) of the gaskets with the inside wall of the tubular wall falling within the range of 150 to 400.
