Description

本発明は一種の注射器の構造に関し、特に針管、シリンダー部及び薬剤を一体化にし、針管を隠すことで、針に刺される憂いを無くす注射器の構造に関する。 The present invention relates to the structure of a kind of syringe, and particularly to the structure of a syringe that eliminates the anxiety of being stabbed by a needle by integrating the needle tube, the cylinder portion and the drug and concealing the needle tube.

通常の医療用注射器には一つのシリンダー、一つの押子及び一つの針管で構成する。従来の注射器は薬剤を注射する前に、まず針管をシリンダーにセットし、更に針管を薬剤瓶の中に挿し込み、シリンダー内に挿設する押子を引っ張ることで、針管から薬剤をシリンダー内に吸引する。そして針管を患者の体に挿入し、押子を押すことで、シリンダー内にある薬剤を患者の体内に注入して薬剤の注射を終える。しかし、従来の注射器は、薬剤を注射する操作過程が比較的面倒であり、また針管は細長い針本体を具有するため、使用する過程において、医療スタッフが針に刺されるアクシデントが発生しやすい。よって、針管の上に一つのプロテクターを套設することで、アクシデントを防ぐ。しかし、薬剤を注入した後、プロテクターを針管に嵌める際に、尚も不注意で針管に刺され、ウィルスを感染する憂いがある。また、従来の注射器及びプロテクターなどの使用量が、大量の医療廃棄物を発生させ、医療廃棄物の処理費用が膨大であることなどを鑑みて、更なる改善が必要であった。 A normal medical syringe consists of one cylinder, one pusher and one needle tube. In a conventional syringe, before injecting a drug, the needle tube is first set in the cylinder, then the needle tube is inserted into the drug bottle, and the pusher to be inserted into the cylinder is pulled to push the drug from the needle tube into the cylinder. Suction. Then, by inserting the needle tube into the patient's body and pushing the pusher, the drug in the cylinder is injected into the patient's body and the injection of the drug is completed. However, in the conventional syringe, the operation process of injecting a drug is relatively troublesome, and since the needle tube has an elongated needle body, an accident in which a medical staff is stabbed by a needle is likely to occur in the process of use. Therefore, by installing one protector on the needle tube, an accident can be prevented. However, when the protector is fitted into the needle tube after injecting the drug, there is still a concern that the needle tube will be inadvertently stabbed and infected with the virus. Further, in view of the fact that the amount of conventional syringes and protectors used generates a large amount of medical waste and the cost of treating the medical waste is enormous, further improvement is required.

図１及び図２に示すように、注射器１の構造とは、主に一つのシリンダー部１０を設け、該シリンダー部１０は蛇腹型にする。該シリンダー部１０内に薬剤Ａを注入し、該シリンダー部１０内の底部に、一つの突起部１００を設ける。該シリンダー部１０の上方に一つの圧縮部１１を設け、該圧縮部１１は円錐状の蛇腹型に設ける。該シリンダー部１０と該圧縮部１１の間に、一つの定位プレート１２を設け、該定位プレート１２の上に一つの穴１２０を設け、底部に一つの固定台１２１を設ける。該固定台１２１内に一つの溝１２２を設け、該固定台１２１の底部縁に、該溝１２２と連通する数個のガイドスロット１２３を設ける。該定位プレート１２の外側壁面に定位ブロック１２４を設け、該圧縮部１１の上方に一つのプレス部１３を設ける。該プレス部１３の中間部位に穿刺面１３０を設ける。該プレス部１３の両サイドを延伸して一つのフランジ部１３１を設ける。該フランジ部１３１の底面には、該定位プレート１２の該定位ブロック１２４と互いに掛止するフック１３２を設ける。一つの針管１４は該定位プレート１２の穴１２０の上に固設し、該針管１４の底端は該固定台１２１の溝１２２内と連通する。該針管１４は該圧縮部１１内に位置し、該針管１４の針先１４０は該プレス部１３の穿刺面１３０の下方に位置する。上述が一つの注射器の構造である。 As shown in FIGS. 1 and 2, the structure of the syringe 1 is mainly provided with one cylinder portion 10, and the cylinder portion 10 has a bellows type. The drug A is injected into the cylinder portion 10, and one protrusion 100 is provided at the bottom of the cylinder portion 10. One compression portion 11 is provided above the cylinder portion 10, and the compression portion 11 is provided in a conical bellows shape. One localization plate 12 is provided between the cylinder portion 10 and the compression portion 11, one hole 120 is provided on the localization plate 12, and one fixing base 121 is provided on the bottom. One groove 122 is provided in the fixing base 121, and several guide slots 123 communicating with the groove 122 are provided on the bottom edge of the fixing base 121. A localization block 124 is provided on the outer wall surface of the localization plate 12, and one press portion 13 is provided above the compression portion 11. A puncture surface 130 is provided at an intermediate portion of the press portion 13. Both sides of the press portion 13 are stretched to provide one flange portion 131. On the bottom surface of the flange portion 131, a hook 132 that hooks with the localization block 124 of the localization plate 12 is provided. One needle tube 14 is fixed on the hole 120 of the localization plate 12, and the bottom end of the needle tube 14 communicates with the inside of the groove 122 of the fixing base 121. The needle tube 14 is located in the compression portion 11, and the needle tip 140 of the needle tube 14 is located below the puncture surface 130 of the press portion 13. The above is the structure of one syringe.

図３から図７に示すように、本発明を使用する際、図３に示す通り、医療スタッフは親指をシリンダー１０の底部を、指二本をプレス部１３にあるフランジ部１３１に添えて、フランジ部１３１及びシリンダー部１０の底部を押すことで、プレス部１３が圧縮部１１を押して定位プレート１２に移動する。圧縮部１１内に位置する針管１４の針先１４０は、プレス部１３の穿刺面１３０を穿刺して突出すると同時に、円錐状の蛇腹型の圧縮部１１がプレス部１３によって押されて圧縮して折り畳んだ状態になる。図４及び図５に示すように、該定位プレート１２の定位ブロック１２４はフランジ部１３１の底部にあるフック１３２内に引掛り、プレス部１３を定位プレート１２に緩まないように定位する。このようにすれば、図６に示すように、患者に対して薬剤を注射するとき、プレス部１３の穿刺面１３０から突出した針管１４の針先１４０を患者の体に挿入した後、シリンダー部１０をプレス部１３の方に向けて押す。蛇腹型のシリンダー部１０は圧縮され、シリンダー部１０内にある薬剤Ａは押されて固定台１２１の底部にある溝１２２及びガイドスロット１２から針管１４内に入る。該薬剤Ａは針先１４０から患者の体内に注入され、シリンダー１０内にある突起部１００が固定台１２１の溝１２２内に入ることで、突起部１００によってシリンダー部１０内にある薬剤Ａを完全に押し出すことができ、薬剤Ａの注射が完了する。薬剤Ａの注射が終ると、図４に示すように、シリンダー部１０とプレス部１３を押す力を緩めるだけで、シリンダー部１０の蛇腹型壁面は弾性力により原状に戻る。更にプレス部１３にあるフック１３２と定位プレート１２の定位ブロック１２４を外せば、該円錐状の蛇腹型の圧縮部１１は弾性によりプレス部１３を上向きに元の位置に押し戻す。当該圧縮部１１とプレス部１３は再び針管１４を隠し、針管１４が露出しないようにすれば、薬剤を注射する動作が完了する。本発明は針管、シリンダー部及び薬剤を一体化することで、針管１４を注射器１の内部に隠すことができ、針に刺される危険性を防止するため、注射器を使用する際、確実に安全性を確保できる。また、別途プロテクターを設置する必要がないため、医療廃棄物の発生及びその処理費用を減少することができ、また薬剤注射の操作過程をよりシンプル化することで、薬剤注射をより便利なものにした。 As shown in FIGS. 3 to 7, when using the present invention, as shown in FIG. 3, the medical staff attaches the thumb to the bottom of the cylinder 10 and two fingers to the flange 131 in the press portion 13. By pushing the bottom of the flange portion 131 and the cylinder portion 10, the press portion 13 pushes the compression portion 11 and moves to the localization plate 12. The needle tip 140 of the needle tube 14 located in the compression portion 11 pierces and protrudes from the puncture surface 130 of the press portion 13, and at the same time, the conical bellows-shaped compression portion 11 is pushed by the press portion 13 to compress. It will be in a folded state. As shown in FIGS. 4 and 5, the localization block 124 of the localization plate 12 is hooked into the hook 132 at the bottom of the flange portion 131, and the press portion 13 is localized on the localization plate 12 so as not to loosen. In this way, as shown in FIG. 6, when the drug is injected into the patient, the needle tip 140 of the needle tube 14 protruding from the puncture surface 130 of the press portion 13 is inserted into the patient's body, and then the cylinder portion. 10 is pushed toward the press unit 13. The bellows-shaped cylinder portion 10 is compressed, and the drug A in the cylinder portion 10 is pushed into the needle tube 14 through the groove 122 and the guide slot 12 at the bottom of the fixing base 121. The drug A is injected into the patient's body from the needle tip 140, and the protrusion 100 in the cylinder 10 enters the groove 122 of the fixing base 121, so that the protrusion 100 completely completes the drug A in the cylinder 10. Can be extruded to complete the injection of drug A. When the injection of the drug A is completed, as shown in FIG. 4, the bellows-shaped wall surface of the cylinder portion 10 returns to its original state due to the elastic force only by loosening the force for pushing the cylinder portion 10 and the press portion 13. Further, when the hook 132 in the press portion 13 and the localization block 124 of the localization plate 12 are removed, the conical bellows-shaped compression portion 11 elastically pushes the press portion 13 upward to its original position. If the compression unit 11 and the press unit 13 hide the needle tube 14 again so that the needle tube 14 is not exposed, the operation of injecting the drug is completed. In the present invention, by integrating the needle tube, the cylinder portion and the drug, the needle tube 14 can be hidden inside the syringe 1, and the risk of being stabbed by the needle is prevented. Can be secured. In addition, since it is not necessary to install a separate protector, it is possible to reduce the generation of medical waste and its disposal cost, and by simplifying the operation process of drug injection, drug injection becomes more convenient. did.

以上の実施例による本発明の詳細な説明は本発明の範囲を制限するものではない。本技術に熟知する者は、固定構造の変更などの適当な変更および調整を行うことができ、これらの変更および調整を行っても本発明の重要な意義は失われず、本発明の範囲に含まれる。 The detailed description of the present invention according to the above examples does not limit the scope of the present invention.
