Abstract
A sterile fluid pathway connector includes a piercing member, a connector hub, and a pierceable seal; wherein at least a portion of the pierceable seal is configured to move from a first position in which the piercing member is retained within a sterile cavity between the pierceable seal and the connector hub, to a second position in which the pierceable seal has been penetrated by the piercing member. A filter may be utilized to enclose the sterile cavity from the outside environment. Such fluid pathway connections may be integrated into a fluid container having a barrel and a plunger seal. The components of the fluid pathway connector may further be capable of transmitting a signal to the user upon completion of fluid delivery, for example, upon contact between the plunger seal and the pierceable seal. A fluid delivery pump includes such integrated fluid pathway connectors and fluid containers.
