PROBLEM TO BE SOLVED: To provide an intravenous drip device which is compact, light-weighted, enables infusion with a fixed pressure from start to finish and is excellent in portability as a device for performing intravenous drip by adding pressure or the like to an infusion solution bag.SOLUTION: A push plate (3) is formed in a case (1), the push plate (3) is attached with a bellows (4) which is evacuated and expandable in the longer direction, and the internal medical fluid is pushed out by pushing and adding pressure to an infusion solution bag (9) held between the push plate (3) and a stationary plate (1A) with the tensile force generated by the differential pressure between air pressure and vacuum.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 輸液バッグに圧力等を加えて点滴を行う装置において、コンパクトで質量も軽くでき、最初から最後まで一定の圧力による輸液が可能な携帯性に優れた点滴装置を実現する。【解決手段】 ケース(1)内に押し板(3)を設け、押し板(3)には内部を真空にした長手方向に伸縮自在なベローズ(4)を取り付け、大気圧と真空の差圧により生じる引張り力で押し板(3)が固定板(1A)との間に挟み込んだ輸液バッグ(9)を押して圧力をかけ、内部の薬液を外へ押し出す。【選択図】図1
