Description
前記器具は、
注射中、遠位方向に前記ピストンに結合されることになっているピストンロッドと、
注射中、前記ピストンロッドを前記容器に関して遠位側に移動させるための付勢手段と、
少なくとも部分的に前記容器、前記ピストンロッドおよび前記付勢手段を受けるように設計されたハウジングと、
前記ピストンが前記容器の前記遠位端の付近にあり、前記製剤が略完全に容器から押し出されると可聴指摘音を発生させることにより、使用者に対して、前記製剤の注射が完了したという指摘をもたらすように設計された制御手段と、を備え、
前記制御手段は、柔軟または破断可能で、注射中、前記ハウジングまたは前記ピストンロッドに直接的または間接的に結合される少なくとも1つの第一の要素と、少なくとも1つの第二の要素と、を備え、前記第二の要素は、注射中、前記ピストンロッドまたは前記ハウジングに直接的または間接的に結合され、前記第一と第二の要素は、注射終了時に前記付勢手段の影響下で相互に協働して、前記可聴指摘音を発生させることを特徴とする。
Claims (2)
- 注射部位(7)に製剤(6)を自動注射する器具(1)であって、前記製剤は容器(2)により担持され、前記容器は、開放近位端(3)と、針(5)を担持して前記容器の製剤排出ポートを提供する、略閉鎖された遠位端(4)と、を有し、ピストン(8)は、前記容器内に設置されて前記容器に関して遠位側に移動可能であり、前記ピストンが遠位側に移動することによって、前記製剤が容器から針を通って押し出され、それによって前記製剤の注射が実現され、
前記器具(1)は、
注射中、遠位方向に前記ピストン(8)に結合されることになっているピストンロッド(9)と、
注射中、前記ピストンロッド(9)を前記容器(2)に関して遠位側に移動させるための付勢手段(18)と、
少なくとも部分的に前記容器(2)、前記ピストンロッド(9)および前記付勢手段(18)を受けるように設計されたハウジング(14)と、
前記ピストン(8)が前記容器(2)の前記遠位端(4)の付近にあり、前記製剤(6)が略完全に容器から押し出されると可聴指摘音を発生させることにより、使用者に対して、前記製剤の注射が完了したという指摘をもたらすように設計された制御手段(13)と、を備え、
前記制御手段は、前記ピストンロッド(9)に直接的または間接的に結合される少なくとも1つの第一の要素(13)と、少なくとも1つの第二の要素(22)と、を備え、前記第二の要素は、前記ピストンロッド(9)に直接的または間接的に結合され、前記第一と第二の要素は、注射終了時に前記付勢手段(18)の影響下で相互に協働して、前記可聴指摘音を発生させ、
前記ピストンロッド(9)は、その近位端にカラー(12)が設けられた中空シリンダ(10)を備え、前記カラーの壁(13)は半径方向に外側に撓み、前記第一の要素は前記カラーの前記壁(13)を含み、
前記器具(1)は、注射中、前記ハウジング(14)に関して固定された長さ方向のロッド(21)をさらに備え、前記長さ方向のロッド(21)は、前記ピストンロッド(9)に関して近位側に離間され、前記長さ方向のロッド(21)の遠位端(21b)は、前記中空シリンダ(10)の中にスライド可能に受けられ、また前記カラー(12)の内径より大きい外径を有する突起(22)が設けられており、前記第二の要素は前記突起(22)を含み、前記突起は、注射終了前は前記カラーの前記壁に緊張力を加え、注射終了時には、前記付勢手段(18)の影響下で、前記カラーから外れることによって前記緊張力を解放することを特徴とする器具(1)。 - 前記第一の要素(13)は、前記付勢手段(18)とは異なることを特徴とする請求項1に記載の器具(1)。
