摘要： A Luer-lock fastening needle hub is proposed. The Luer-lock fastening needle hub has an insertion groove for a front end of a tapered tube of a barrel to receive the tapered tube into which a plunger is inserted, so that a plunger contact surface is inserted into the tapered tube of a front discharge end of the barrel. The Luer-lock fastening needle hub has a needle cap fastening grooves formed along an outer circumference thereof and “V”-shaped insertion guides are formed in four direction at front portions of openings of the needle cap fastening grooves, so that fastening protrusions formed on an inner surface of a needle cap are unaffectedly guided by the “V”-shaped insertion guides and are easily aligned and fastened to the needle cap fastening grooves.

摘要： A device for adjusting the tightening angle of a needle safety protector is proposed. The device is configured to provide an injection needle in an integrated state with a needle hub for preventing reuse of the injection needle and to fasten the needle hub to a needle safety protector that is disposed of in a folded state after use, a fastening structure is improved such that rotation is possible by a predetermined angle when the needle safety protector is rotated. Accordingly, an injection is safely performed by correcting the injection needle to the reference direction. In addition, even when a syringe is assembled by deviating from a reference angle during the mass production with the automatic line, the wrong angle is corrected in use.

摘要： A syringe with plunger reaction pressure reduction structure is proposed. The syringe includes: a barrel including a finger grip at a rear end thereof and a Luer-lock connector in which a thread portion is formed on an inner surface outside a tapered tube of a front discharge end thereof; a plunger rod configured to be inserted in an inside of the barrel and including a push end at a rear end thereof; a plunger coupled to a front end of the plunger rod; and a needle hub configured to be screwed with the Luer-lock connector and including an injection needle mounted to a front end thereof. The syringe is configured to have a three-step structure at the plunger in which intervals between steps are gradually shortened, so that the reaction pressure applied to the plunger is distributed and the injection is easily performed.
