摘要:
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.
摘要:
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.

摘要:
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.
摘要:
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.
摘要:
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.
