    摘要： Provided is a syringe for injecting a drug solution into an upper layer of skin that injects a drug solution such as a vaccine into an upper layer of skin, and particularly selectively into a relatively shallow site near an epidermic layer in a dermic layer to form a bulge without the occurrence of a leak from a skin surface, regardless of an age difference, a gender difference, and an individual difference, whereby a sufficient drug effect such as immunity elicitation capability can be obtained or exhibited even by a very small amount. The syringe for injecting a drug solution into an upper layer of skin 1 includes: an injection needle 20 provided with a needle hole 24 communicating from a needle tip 21 to a needle proximal end, and having a blade face 22 at the needle tip 21; and a needle hub 30 having a distal end portion 31c and a proximal end portion, and holding the injection needle 20 at the distal end portion 31c, wherein the needle hub 30 has a needle tip side end face 31b, and the needle tip 21 protrudes from the needle tip side end face 31b, and a protruding needle length L 1 of the needle tip 21 from the needle tip side end face 31b is 1.15 mm ± 0.1 mm, and a blade face length L 2 of the blade face 22 along an axis of the injection needle 20 is 0.60 mm ± 0.15 mm.

    摘要： A drug injection syringe that has a reduced dead volume to reduce an amount of remaining drug and can efficiently inject a small amount of drug into a body without leakage is provided. A drug injection syringe 1 includes an injection needle assembly 50 including a needle hub 80 for supporting an injection needle 90, an elastic body 70 mounted on the needle hub 80, the injection needle 90 being inserted in the elastic body 70, and a fitting sleeve 60 accommodating the needle hub 80 and the elastic body 70 and including an opened fitting hole 61 having a female taper 63, and a syringe body 10 including an outer tube 30 for containing drug 31 in a sealed manner and a drug discharge tube 40 having a male taper 43 that fits into the female taper 63, the syringe body 10 and the injection needle assembly 50 being coupled together by pushing the drug discharge tube 40 into the fitting hole 61 by press fitting. The elastic body 70 has a pocket 73 opening to a contact surface that makes contact with a distal end of the drug discharge tube 40, and couples together the drug discharge tube 40 and the injection needle 90 in a liquid-tight manner by compressively deforming, by the press fitting, at a protruding portion 72 provided on a periphery of the pocket 73 to stretch against an inner wall of the fitting hole 61, thereby providing liquid-tightness.

    摘要： Provided is a syringe container allowing a syringe to be pulled out therefrom without raising a syringe holding section. The syringe container 1 includes a syringe 10, a cap 30, a syringe holding section 40, and a container body 50. The syringe 10 includes a discharge section 12, a flange section 16, and a side peripheral section 11 continued to the discharge section 12 and the flange section 16. The cap 30 attached to the discharge section 12 has an outer radius R2 larger than an outer radius R1 of the side peripheral section 11. The container body 50 including an opening 53 in the upper portion is formed in a square-box-shape. The syringe holding section 40 placed in the container body 50 has a through-hole 43 in which the syringe 10 is vertically inserted to be held therein, and holds the syringes 10 by inserting the syringe 10 in the through-hole 43. The inner peripheral surface 44 forming the through-hole 43 is formed to have an upper end of which radius is larger than the outer radius R2 of the cap 30, a bottom end of which radius R4 is larger than the radius of the upper end, and a tapered section 45 having a diameter reducing from the bottom end as the tapered section 45 extends upward.

    摘要： [Problem] To provide an injection needle assembly and a medicine injection apparatus in which it is possible to position a needle tube reliably in an upper layer region of a skin even in a case in which the pressing force to the skin is strong. [Solving Means] An injection needle assembly 2 includes a needle tube 5 having a needle tip 5A to be stuck into a skin, a first member 11, a second member 12, an adjustment portion 22, and a pressing force restricting member 15. The first member 11 holds the needle tube 5 and the second member 12 holds the first member 11 movably toward the axial direction of the needle tube 5. A discharge portion of the syringe 3 is fitted into this second member 12. The adjustment portion 22 is provided at the periphery of the needle tube 5 and includes a needle protrusion surface 22A which abuts the skin in a case in which the needle tube 5 is stuck to the living body. The pressing force restricting member 15 is arranged between the first member 11 and the second member 12, and restricts the pressing force added from the first member 11 to the skin.
