PROBLEM TO BE SOLVED: To provide a pump module to be filled with an infusion without leaving air inside a solution chamber when usage is started, and also to provide an infusion pump system including the pump module.SOLUTION: The pump module includes: a case 70 and a pump 13 located in the case for sending a solution according to changes in a volume of a space 35 where the solution flows in and out. The space 35 includes: an opening 73 for introducing the solution and an opening 74 for discharging the solution. The case 70 includes: an opening 71 for introducing the solution and an opening 72 for discharging the solution. Among the angles to be formed by a direction for introducing the solution into the opening 71 and a direction for discharging the solution from the opening 74 of the space 35, an angle between the opening 71 and the opening 74 is greater than or equal to zero degrees and less than 90 degrees. The opening 71 and the opening 73 are connected by a flow path 75 for introducing the solution into the case and the solution chamber. The opening 72 and the opening 74 are connected by a flow path 76 for discharging the solution from the solution chamber and the case.COPYRIGHT: (C)2012,JPO&INPIT【課題】使用開始時に液室内に空気が残らず、輸液で満たされるポンプモジュール及びそのポンプモジュールを有する輸液ポンプシステムを提供する。【解決手段】ケース70と、液体が出入りする空間35の容積の変化に伴って送液を行うケース内のポンプ13と、を有し、空間35は、液体を導入する開口部73と、液体を吐出する開口部74を備え、ケース70は、液体を導入するための開口部71及び液体を排出するための開口部72を備え、開口部71への液体の導入方向と空間35の開口部74からの液体の吐出方向とが形成する角度のうち、開口部71及び開口部74に挟まれる角度が0度以上90度未満であり、開口部71及び開口部73は、ケース内及び液室内に液体を導入するための流路75によって連通され、開口部72及び開口部74は、液室及びケースから液体を排出するための流路76により連通する。【選択図】図4
