Zusammenfassung:To provide an occlusion assembly for closing a folding type tube of a medical infusion device.SOLUTION: An occlusion assembly includes: first and second occlusion members which are positioned to be opposite from each other to be adjacent respectively to paired first and second foldable tubes such that a space is formed between them, while the space is located on the opposite side of the foldable tubes, and the occlusion members are adjacent to the foldable tubes; an expanding portion which forcibly moves portions of the occlusion members in a manner to be separate from each other to increase the size of the space, and forcibly moves a tube contact portion of each of the occlusion members relative to the foldable tubes adjacent to the occlusion members such that the foldable tubes are closed; and an actuator configured and positioned for moving the expanding portion.SELECTED DRAWING: Figure 54 【課題】医療用注入装置の折畳み式チューブを閉鎖するための閉鎖アセンブリを提供する。【解決手段】第1および第2の閉鎖部材は対の第1および第2の折畳みチューブにそれぞれ隣接してそれらの間に空間が形成されるように互いに対向するように位置決めされ、空間は折畳み式チューブとは反対側に存在しており、閉鎖部材は折畳み式チューブに隣接する、第1および第2の閉鎖部材と、閉鎖部材の一部を空間のサイズを増大させるために互いから離れるように強制的に移動させ、各閉鎖部材のチューブ接触部を、折畳み式チューブを閉鎖するように閉鎖部材が隣接する折畳み式チューブに対して強制的に移動させる、広がり部と、広がり部を移動させるように構成され位置決めされるアクチュエータと、を備える閉鎖アセンブリを提供する。【選択図】図54
