Publication number: 20160151566Abstract: Pump cassettes, infusion systems, and methods are described. An example infusion pump system may include a cassette recess with one or more valve actuators that extend through a surface of the cassette recess to operate a corresponding valve in a fluid passageway of a pump cassette mounted in the cassette recess. The valve actuator may include a base portion, a shaft extending from the base portion through the surface, and a spring disposed on the shaft and extending along a portion of the shaft. The spring may be disposed interior to the back surface. The system may include first and second valve actuators configured to operate corresponding first and second valves located on opposing sides of a pump chamber of the fluid passageway. A piston may be configured to cooperate with the first and second valve actuators to pump a fluid through the fluid passageway.Type: ApplicationFiled: June 24, 2015Publication date: June 2, 2016Inventors: Corey Michael MAGERS, Edward BROWKA

Publication number: 20160067410Abstract: A filtered needle for use in administering a liquid payload, including a needle and connector portion and a filtering needle cap. The filtering needle cap including a distal open end in fluid communication via an internal channel with a proximal open end of the filtering needle cap. The filtering needle cap proximal end sized to receive the distal end of the hub within the proximal end of the filtering needle cap to reversibly engage the hub when needle distal end is inserted into the internal channel. The filtering needle cap including a filter element and a seal to seal around an outside diameter of the hollow needle so that liquid payload is drawn into the lumen in the hollow needle as liquid payload is filtered and drawn into the fluid fitting. The filtering needle cap is designed to limit a dead volume of liquid payload drawn into the filtering needle cap but not entering into the distal end of the hollow needle.Type: ApplicationFiled: November 16, 2015Publication date: March 10, 2016Inventors: Sue E. Carr, Jessie Delgado, Edward Browka, Charles E. McCall, JR., David L. Foshee

Publication number: 20150313796Abstract: In one aspect, the invention is directed to a port assembly for establishing fluid communication between a first container and a second container. The port assembly includes a retainer for connecting a first container, where the retainer is positioned in a cavity defined by a port housing that includes an axially fixed actuator. The housing also includes a plug member constructed to seal a fluid passageway between the port housing and an interior of a second container. The plug member is configured to move axially relative to the actuator. Rotation of the retainer relative to the actuator causes the plug member to move to an open position in which it does not seal a fluid passageway between the port housing and an interior of a second container. The rotation of the retainer relative to the port housing also causes the retainer to move axially relative to the port housing so that the actuator forces a stopper associated with a first container connected to the retainer into a first container.Type: ApplicationFiled: July 9, 2015Publication date: November 5, 2015Inventors: John A. Domkowski, John Sundquist, Benjamin Leo Rush, David L. Foshee, Theodore J. Mosler, Edward Browka

Patent number: 8911421Abstract: A system for mixing the contents of a first container and a second container. The system includes the first container that has container body with an opening fluidly connected to a cavity defined by the container body, a first substance contained in the cavity, and a stopper sealing the opening. The second container includes a port assembly including a port housing connected to the second container and a retainer constructed to connect to the first container. The retainer is configured to rotate and move axially relative to the port housing, wherein relative rotation between the port housing and the retainer causes the retainer to move axially relative to the port housing. The port assembly further includes an axially fixed actuator constructed to force the stopper into the first container when the retainer is rotated relative to the port housing.Type: GrantFiled: October 3, 2012Date of Patent: December 16, 2014Assignee: Hospira, Inc.Inventors: John A.

Patent number: 8882739Abstract: A port assembly for establishing fluid communication between a first container and a second container. The port assembly includes a port housing for connection to a second container, and a retainer for connection to a first container, wherein the retainer rotates relative to the port housing and is constructed to move axially within the port housing. An actuator is axially fixed within the port housing and forces a stopper associated with a first container into a first container when the retainer moves axially within the port housing upon rotation of the retainer relative to the port housing. The assembly is configured to establish fluid communication between a first container and a second container upon rotation of the retainer relative to the port housing.Type: GrantFiled: October 3, 2012Date of Patent: November 11, 2014Assignee: Hospira, Inc.Inventors: John A.

Publication number: 20060229562Abstract: A method and apparatus for injecting fluid into areas having high density tissue that creates a high backpressure resistance on the injection device is disclosed. The high backpressure resistance is overcome through a mechanical advantage achieved by using a secondary reservoir having a cross-sectional area smaller than the cross-sectional area of a primary reservoir. Exemplary injection device reservoir housings may comprise a primary reservoir, a secondary reservoir, a check valve, a septum penetrating cannula, travel limits, a pen needle connecting portion, sliding seal guide ribs, a sliding seal, a pen needle assembly, a needle stop, and a patient needle.Type: ApplicationFiled: April 11, 2005Publication date: October 12, 2006Inventors: Ronald Marsh, Mark Follman, Edward Browka

Publication number: 20060229570Abstract: An injectable substance delivery device comprising a pen device body, a cartridge, a plunger, a drive mechanism, and at least one of a lock-out mechanism and a rate-limiting mechanism. The lock-out mechanism is provided through a ratchet engagement between the body and the plunger to restrict plunger movement and to ensure that the required needle puncture depth is realized prior to injection by locking out the injection mechanism from advancing until a specified force is applied to the skin. A rate-limiting mechanism is also provided through a user compressed plunger drive spring to ensure that a specific rate of injection is realized during the injection of a medicament.Type: ApplicationFiled: April 11, 2005Publication date: October 12, 2006Inventors: John Lovell, Robert West, Todd Chelak, William Easterbrook, Mark Follman, Edward Browka
