Integrated pierceable seal fluid pathway connection and drug containers for drug delivery pumps
First Claim
1. A sterile fluid pathway assembly comprisinga sterile fluid container;
- a sterile fluid conduit; and
a sterile fluid connector comprisinga first portion configured to connect the sterile fluid conduit; and
a second portion configured to mount the sterile fluid container;
a connector hub;
a pierceable seal disposed at least partially between the connector hub and a sterile fluid chamber of the sterile fluid container, the pierceable seal in sealing contact with the connector hub to form a sterile cavity between the connector hub and the pierceable seal; and
a piercing member fixedly disposed within the connector hub capable of providing a sterile fluid communication between the sterile fluid chamber and the sterile fluid conduit;
wherein at least a portion of the pierceable seal is configured to transform from a non-activated state wherein the pierceable seal is intact, to an activated state wherein the pierceable seal is disrupted by the piercing member to create a sterile fluid communication between the sterile fluid chamber of the sterile fluid container and the sterile fluid conduit; and
wherein the sterile fluid container comprises a plunger seal and translation of the plunger seal results in relative motion of the pierceable seal and the piercing member.

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.

5. An infusion pump device comprising
an insertion mechanism; - and
a sterile fluid pathway assembly comprising a sterile fluid container; a sterile fluid conduit; and a sterile fluid connector comprising a first portion configured to connect the sterile fluid conduit; and a second portion comprising a housing configured to mount a sterile fluid container; a connector hub; a pierceable seal disposed at least partially between the connector hub and a sterile fluid chamber of the sterile fluid container, the pierceable seal in sealing contact with the connector hub to form a sterile cavity between the connector hub and the pierceable seal; and a piercing member fixedly disposed within the connector hub, capable of providing a sterile fluid communication between the sterile fluid chamber and the sterile fluid conduit; wherein at least a portion of the pierceable seal is configured to transform from a non-activated state wherein the pierceable seal is intact, to an activated state wherein the pierceable seal is disrupted by the piercing member to create a sterile fluid communication between the sterile fluid chamber of the sterile fluid container and the sterile fluid conduit; and wherein the sterile fluid container comprises a plunger seal and translation of the plunger seal results in relative motion of the pierceable seal and the piercing member; wherein actuation of the drive mechanism causes fluid movement from the sterile fluid container through the sterile fluid pathway assembly to the insertion mechanism. - View Dependent Claims (6, 7, 8, 12, 13)
