PROBLEM TO BE SOLVED: To provide a pseudo experience device that allows the pseudo-experience fluid administration operation to be experienced and capable of reducing an expense as a result of the device being repeatedly available.SOLUTION: A pseudo experience device 10 for pseudo-experiencing the administration operation of an instrument for administering a liquid into a living body includes: an operation member 40 a structure 21 movable to the operation member 40 a cover member 50 movable to the structure 21 and a first coil spring 22 for energizing the cover member 50 to the structure 21 in a top end direction thereof. A first engaging part 43 is formed on the operation member 40, and a second engaging part 53 is formed on the cover member 50. The operation member 40 moves to a top end direction for the structure 21. The first engaging part 43 and the second engaging part 53 are engaged with each other so that the operation member 40 is prevented from moving to a proximal end direction for the cover member 50 in a state that the cover member 50 moves to the top end direction for the structure 21.COPYRIGHT: (C)2015,JPO&INPIT【課題】液体の投与操作を疑似的に体験でき、かつ繰り返し利用可能となって経費を削減できる疑似体験デバイスを提供する。【解決手段】液体を生体内へ投与するための器具の投与操作を疑似的に体験するための疑似体験デバイス10であり、操作部材40と、操作部材40に対して移動可能である構造体21と、構造体21に対して移動可能であるカバー部材50と、カバー部材50を構造体21に対して先端方向へ付勢する第1コイルバネ22とを有し、操作部材40に第1係合部43が形成されるとともにカバー部材50に第2係合部53が形成され、操作部材40が構造体21に対して先端方向へ移動し、かつカバー部材50が構造体21に対して先端方向へ移動した状態において、操作部材40をカバー部材50に対して基端方向へ移動不能となるように第1係合部43および第2係合部53が係合するとともに、当該係合を解除可能である。【選択図】図2
