Abstract
A fluid pathway connection includes a piercing member, a connection hub, and a sliding pierceable seal, wherein the sliding pierceable seal is configured to move from a first position, where the piercing member is initially retained within a sterile cavity between the connection hub and the sliding pierceable seal, to a second position, where the pierceable seal has been penetrated by the piercing member. A filter may be utilized to enclose the sterile cavity from the outside environment. The fluid pathway connection may further be configured to move to a third position where one or more interconnects and/or one or more corresponding contacts are permitted to transmit a signal to the user. Such fluid pathway connections may be integrated into a drug container having a barrel and a plunger seal. A drug delivery pump includes such integrated fluid pathway connections and drug containers.
