Zusammenfassung: | To provide a syringe and a syringe unit free from the need of excessive shifting and reducing a load on a person to be injected.SOLUTION: A syringe comprises a syringe part having a body part formed with an opening, a conversion part, a button part and a slider part. The button part has a pair of leg parts arranged across the conversion part and having a front inclined surface inclined only at a set angle in the tip direction. The conversion part has a pair of engaging parts connected to a rear end of a gasket and having a rear inclined surface in slide contact with the front inclined surface of the leg part. The slide part moves the conversion part and the button part in the tip direction. The conversion part is moved together with the gasket in the tip direction in accordance with operation of pushing down the button part into the inside of the body part. A syringe unit has a syringe, and one or a plurality of adjustment members for adjusting a foremost position of the button part in the opening. The adjustment member has a spacer having a set width and arranged between both lateral walls of the opening.SELECTED DRAWING: Figure 1
【課題】過度な持ち替えを要さず、被注射者の負担を軽減する注射器及び注射器ユニットを提供すること。【解決手段】開口部が形成された本体部をもつシリンジ部と、変換部と、ボタン部と、スライダ部と、を有する注射器。ボタン部は、変換部を跨いで配置され、先端方向に対し設定角度だけ傾斜した前斜面をもつ一対の脚部を有している。変換部は、ガスケットの後端部に連結されており、脚部の前斜面に摺接する後斜面をもつ一対の係合部を有している。スライダ部は、変換部及びボタン部を先端方向へ移動させる。変換部は、ボタン部を本体部の内側に押し下げる操作に応じて、ガスケットと共に先端方向へ移動する。注射器ユニットは、注射器と、開口部内でのボタン部の最前の位置の調整用である1又は複数の調整部材と、を有する。調整部材は、設定された幅をもち、開口部の両側壁の間に配置されるスペーサを有する。【選択図】図1 |
