摘要：
A valve for an infusion pump device comprising a pump connection fluidly connected to a piston pump, an infusion site connection fluidly connected to an infusion set, and a reservoir connection fluidly connected to a reservoir is presented. The valve is in a first state (I) when the pump connection is fluidly connected to the infusion site connection and the reservoir connection is sealed closed and in a second state (II) when the pump connection is fluidly connected to the reservoir connection and the infusion site connection is sealed closed. The valve comprises one or more conduits, grooves, and/or recesses connected to environment and arranged so that no path exists within the valve between the infusion site connection and the reservoir connection that does not cross at least one of the conduits, grooves, and/or recesses, establishing a drain, independently if a path is closed during normal operation of the valve.
摘要（中）：
一种用于输液泵装置的阀，包括流体连接到活塞泵的泵连接件，流体连接到输注器的输注部位连接件和流体连接到储液器的储液器连接件。 当泵连接流体地连接到输液部位连接时，阀处于第一状态（I），并且当泵连接流体连接到储存器连接时，储存器连接被密封并处于第二状态（II），并且 输液部位连接密封。 该阀包括连接到环境并布置成一个或多个导管，凹槽和/或凹部，使得在输注部位连接和储存器连接之间的阀内不存在路径，该路径不与管道，凹槽和/ /或凹槽，如果在阀的正常操作期间路径闭合，独立地建立排水管。
