  • Publication number: 20180078714
    Abstract: An injection needle is provided that allows design of the size of a needle base without being limited by the size of a syringe connecting part. As a hub, a needle base that is formed to have a through hole into which a needle tube is inserted, and a tubular housing where both ends in the axial direction are opened and the needle base is fitted and stored inside of one end, are formed as separate injection molded parts, thereby allowing the needle base to be largely designed. A needle tube shield part is in a box-lid shape, and the back side of a ceiling part thereof is provided with a tubular guiding part. An edge surface thereof abuts on the needle base, and a side part annularly holds and abuts on the housing. Accordingly, the needle base does not move upon receiving the pressure of a drug solution.

  • Patent number: 9808583
    Abstract: A percutaneous medication device, comprising a syringe to be filled with medical liquid and a needle formation attached to a leading-end of the syringe is provided. The needle formation comprises a needle formation body, from the surface of which a needle projects and a cover portion covers a leading-end of the needle formation body. The needle is inserted into a through-hole formed at the leading-end of the needle formation body and fixed by a fixation member. The needle formation body is mated to the cover portion, a space is formed between an inner surface of the cover portion and the leading-end of the needle formation body, and the needle projects from the leading-end surface of the cover portion through a needle insertion hole formed at the leading-end of the cover portion.

  • Publication number: 20160279346
    Abstract: A drug solution injection needle is provided that can not only inject a drug solution from multiple locations, but also restrict the depth of puncture by injection needles while preventing an observable wheal from being unlikely to form. The drug solution injection needle has multiple injection needles and a needle support for supporting the plurality of injection needles. The needle support has: a needle protruding surface from which the multiple injection needles protrude out; and an abutment fragment, which is formed in the needle protruding surface and abuts the skin to obstruct the multiple injection needles from entering the skin when the multiple injection needles have entered the skin to a predetermined depth. The abutment section is provided away from the injection needles such that an observable wheal is formed around each of the multiple injection needles.
