Abstract
Description
本発明は注射器の注射針の形状に関するものである。 The present invention relates to the shape of an injection needle of a syringe.
従来の注射器の注射針の先端は、中空の注射針体の先端を斜めにカットして鋭利に研磨してある。これによって目的個所の皮膚、血管、筋肉内へ針先を刺入して薬液を注入するか、または血液を採取している。しかしこの方式は刺入の際に皮膚、血管、筋肉等の組織を切断して刺入するために、患者に非常な痛みを与える上、出血を起こさせる。又刺入痕は切り傷であるので出血止め、化膿防止其の他の衛生的処置をしても回復に相当の時間を要する。また刺入個所を傷つけることにより繰り返せばその個所は皮膚、筋肉が硬化する。The tip of the injection needle of a conventional syringe is sharply polished by cutting the tip of a hollow injection needle body obliquely. As a result, the needle tip is inserted into the skin, blood vessel, or muscle of the target site, and a chemical solution is injected, or blood is collected. However, this method cuts tissue such as skin, blood vessels, muscles and the like when inserting, and causes great pain to the patient and causes bleeding. Moreover, since the puncture mark is a cut, it takes a considerable amount of time to recover even if it is used to stop bleeding, prevent suppuration or other hygienic measures. If it is repeated by hurting the puncture site, the skin and muscles will be cured.
又点滴用の輸液のバッグや容器の栓などに針を刺入して薬液を吸い出すことにも使用しているが、その場合に太い針を使用すれば、この栓の素材の砕片を薬液中に混入するおそれもある。 It is also used to insert a needle into an infusion bag or container stopper for infusion, and to suck out the chemical. In this case, if a thick needle is used, the debris of this stopper will be removed from the chemical. There is also a risk of contamination.
解決しようとする問題点は、注射針の刺入時の疼痛を無くするか、もしくは微かにして患者のストレスを取り除いて治療効果を高めると同時に刺入個所の傷を最小限として将来の皮膚、筋肉の硬化を防ぎ、又薬液注入の際には栓の素材の砕片の混入をも防止できる。 The problem to be solved is to eliminate the pain at the time of needle insertion or remove the stress of the patient to enhance the treatment effect and at the same time minimize the wound at the insertion site, Muscle hardening can be prevented, and contamination of the plug material can also be prevented when the chemical solution is injected.
本発明は、上記の目的を達成する為に注射針の形状をいわゆる松葉型と称する尖端の形とし、薬液の注入孔は針の太さ、注射の使用目的により異なるが、概ねその先端より2〜4mmくらい隔てた所に2〜6箇所、針体に直角にあける。 In the present invention, in order to achieve the above object, the shape of the injection needle is a so-called pine needle shape, and the injection hole for the chemical solution varies depending on the thickness of the needle and the purpose of use of the injection. Place 2-6 locations at a distance of ~ 4mm, and perpendicular to the needle.
この発明は上記のように注射等を行う場合の針の刺入時には、無痛、もしくは微かな痛みである上、処置後も出血を見ないか、あっても従来の方法による場合と比較して極めて少ない為に、患者は安心して注射、採血などを受けることが出来るので無用なストレスを与えない為、大きな治療効果をあげることが出来る。また輸血、点滴等の場合も同様な上砕片など異物の混入の心配は全くないので安心である。 This invention is painless or slightly painful at the time of needle insertion when performing injection or the like as described above, and does not see bleeding even after treatment, even if compared with the case by the conventional method Because it is extremely small, the patient can receive injections, blood collection, etc. with peace of mind, so that unnecessary stress is not applied, and a great therapeutic effect can be achieved. In the case of blood transfusion, infusion, etc., there is no worry of foreign matters such as the same top fragments, so it is safe.
点滴用輸液のバッグや容器の栓などに刺入した場合もそれらの栓の素材の砕片などは発生しないので薬液には異物は混入しない。 When inserted into a drip infusion bag or a container stopper, no fragments of the stopper material are generated, so no foreign matter is mixed into the drug solution.
以上により注射等で針を刺入する時には、針の尖端を皮膚に押し込むことになるので、皮膚、又は血管などの組織を切断、損傷することなく、その組織を押し広げながら刺入する事となる為に患者は無痛、もしくは微かな痛みを感じるのみとなる。 When the needle is inserted by injection or the like as described above, the tip of the needle is pushed into the skin, so that the insertion is performed while expanding the tissue without cutting or damaging the tissue such as the skin or blood vessels. Therefore, the patient feels no pain or only slight pain.
