摘要:
Various embodiments of the present invention are directed to equalizingpressure in a reservoir containing fluidicmedia, possibly due to imperfect installation of the reservoir or an externalinfluence such as an altitude or a temperature change. Invarious embodiments, fluidic media may be expelled from the reservoir througha needle and contained in an interior volume of apierceable member before the needle pierces the pierceable member to establisha flow path to a user. In other embodiments, fluidicmedia may be expelled through a port of the reservoir into a chamber. Infurther embodiments, fluidic media may be expelled througha channel in a plunger head and out a passage in the reservoir when thechannel and passage are aligned. In other embodiments,fluidic media may be expelled through a valve, and the valve may be pierceableby a needle to establish a flow path to the user.
