Abstract
【解決手段】注射の過程において、医療看護人員は注射後の注射針45を、プランジャー20の端部分で押して駆動部品のピストン31を前進させると同時に、端部分の切断面231と針座の切断面412が相互に圧力を受け、離脱状態になる。また、ピストン31を継続して押すことにより、その中の気体の圧力を受け、針座40をプランジャー収納室21内部に引き込み、注射後の注射針45を安全に収納する。
【選択図】図2
Description
(1)安全性に欠ける:注射器で使用者の身体部位に注射する場合、医療注射の過程に注射器には注射針を収納する設計がなされていない。注射後に再び、外に露わになった注射針に針カバーをかける。もしうっかり注射針で刺してしまうと、重大な危険が生じる。
(2)使用効果が優れない:注射器は注射の機能を持ち、注射器の注射針は凸出設計となっており、注射器の注射針で注射後、注射針と針カバーの被せる動作が必須である。医療看護人員は必ず手順を銘記しなければならず、操作に誤って注射針で刺し傷を負う状況が発生し、注射器により医療人員に感染する可能性を上げる。
請求項2の発明は、第一棒部の一端の延長に座体があり、座体側面には凹縁の切断面を設け、駆動部位の一側に嵌り込むことを特徴とする請求項1に述べる安全注射器としている。
(2)良好な注射効果を提供する:注射筒カバーは注射筒に被せることができ、プランジャー収納室内部に引き込んだ針座上の注射針は注射筒カバーの上蓋で閉じ込められ、回収運搬過程にて刺し傷を負わず安全効果を大幅に向上させる。
