Abstract
【解決手段】薬液が充填される円筒状のシリンダ7と、先端に注射針10が装着されシリンダ7の先端側に設けられた筒先と、シリンダ7の後端側に設けられたフィンガーグリップ9とを備えた容器兼用注射器1において、円筒形状を有し、シリンダ7の外周に摺動可能に装着され先端方向に移動した際に注射針10を覆うセーフティーデバイス3と、前記セーフティーデバイス3を前記注射針10から外れた第一位置と、前記注射針10を覆う第二位置とに選択的に係止する保持手段17、18と、セーフティーデバイス3を第二位置方向に付勢するコイルスプリング20とを設ける。
【選択図】図1
Description
即ち、本発明に係る容器兼用注射器は、薬液が充填される円筒状のシリンダと、先端に注射針が装着され前記シリンダの先端側に設けられた筒先と、前記シリンダの後端側に設けられたフィンガーグリップとを備えた容器兼用注射器において、円筒形状を有し、前記シリンダの外周に摺動可能に装着され先端方向に移動した際に前記注射針を覆うセーフティーデバイスを備え、前記セーフティーデバイスを前記注射針から外れた第一位置と、前記注射針を覆う第二位置とに選択的に係止する保持手段と、前記セーフティーデバイスを前記第二位置方向に付勢する付勢手段とが設けられたことを特徴としている。
まず、図3に示すセーフティーデバイス本体4の先端側から、その外周壁4bに押圧リング5を嵌め込み後端方向にスライドさせると、押圧リング5はその可撓性によってリング一次停止突起33を越えて、押圧リング5の後端がリング二次停止突起32bの傾斜面に接触して停止する。この状態において、押圧リング5は、図7に示すように、後端側がリング二次停止突起32bの傾斜に当接され、先端側がリング一次停止突起33に当接されることによって、多少の力では移動されない程度に固定され、セーフティーデバイス3が構成される。
