Abstract:
A system for providing the collection of advanced, improved, and novel new components and elements in a single package to simplify assembly and use of the infusion set by the user, including one or more of an exemplary pushbutton-type inserter, squeeze-type inserter, contact-type inserter, skin pinching-type inserter, folding retraction-type inserter, and/or multistage-type inserter (700) having at least one reusable stage, an exemplary set (350) having an adhesion means with two or more user-selectable degrees of adhesion strength, a self-sealing tube connection means, a lens feature to view a site beneath the set, exemplary tube management and connection elements (450), insulin supply (475), adhesion concealment means (500), finger loops on the inserter and site preparation wipes or sprays (550) which can be provided as part of the inserter. The system can further include an exemplary package (12) which can hold a number of sets that can be easily released and retrieved from the tray by an inserter, an exemplary insertion needle handle and shroud, an exemplary squeeze-type latch between an upper portion and a lower portion of the set, and/or a tool removable upper portion of the set.
Abstract:
A high pressure delivery system for delivering a medicament, comprising a first chamber for storing a supply of the medicament, a gear pump assembly in fluid communication with the first chamber, said gear pump assembly having a dose inlet and a dose discharge, said dose inlet having a larger diameter than said dose discharge to provide a high pressure discharge, and a fluid connection path in fluid communication with the gear pump assembly for delivering the medicament to a high pressure area.
Abstract:
Vial dosing systems and methods are disclosed. A vial dosing device includes a connecting body coupleable to a vial, a cannulated plunger having a proximal end coupled to the connecting body, a dose chamber adapted to slidably receive a distal end of the cannulated plunger and to expel medicament through a distal end of the dose chamber, and a plunger tip check valve coupled to the cannulated plunger and adapted for fluid flow from the cannulated plunger through the plunger tip check valve into the dose chamber.
Abstract:
In one aspect, a pen needle assembly is provided herein which includes a hub, and a needle fixed to the hub, the needle having proximal and distal ends with a lumen extending therebetween. The needle extends distally from the hub to define an exposed length between the distal end of the needle and the hub in the range of about 5.0 to 9.0 mm. The hub defines a post formed about the needle, the post having a distally-facing first skin engaging surface. The exposed length of the needle extends distally from the first skin engaging surface. The hub also defines a distally-facing second skin engaging surface which at least partially circumscribes the first skin engaging surface. The second skin engaging surface being located proximally of the first skin engaging surface. Advantageously, a pen needle assembly is provided having two skin engaging surfaces which provide stability in achieving subcutaneous injections.
Abstract:
An apparatus is disclosed for storing and changing needles for connection with a medicament delivery device, comprising an inner housing, a reservoir disposed within the inner housing, and a needle holder disposed within the inner housing, for fluidly connecting a medicament container of the medicament delivery device with the reservoir. The apparatus also includes a plurality of patient needles displaceably disposed on the needle holder, and an outer housing displaceably disposed about the inner housing and providing a user interface to individually select one of the plurality of patient needles, connect the selected needle with the reservoir, expose the selected needle outside of the apparatus for injection, and store the selected needle.
Abstract:
A method of amplifying an injection force of a drug delivery device, comprising the steps of storing energy in an additive force device, connecting the additive force device to the drug delivery device, setting a dose of medicament to be administered, and selectively releasing the stored energy of the additive force device to amplify an injection force of the drug delivery device.
Abstract:
A package for a medical cannula with a hub, such as a pen needle, is disclosed. The package includes a cover for receiving a medical cannula and for engaging a hub of the medical cannula. The cover has open ends that are in communication through the cover. The packaging also includes a sterility barrier for the cover.
Abstract:
A pen needle, comprising a reusable adapter configured for attachment to a distal end of a medication pen, the adapter having a proximal needle for accessing the interior of the pen injector and a fitting on the distal side for mating with a patient end needle assembly, and a disposable patient-end needle assembly having a base configured for mating with the fitting on the distal side of the adapter and a patient-end needle extending from a distal end of the base.
Abstract:
In one aspect, a safety pen needle assembly is provided herein which includes a hub with a needle fixed to the hub, the needle having a distal end, formed for insertion into a patient, and a proximal end. The assembly further includes a shield and a biasing member disposed between the hub and the shield configured to urge the shield distally. A protrusion extends from at least one of the hub and the shield with a channel being formed in at least the other of the hub and the shield. The channel is formed to accommodate the protrusion. The shield is movable from a first position to a second position. In the first position, the shield is spaced from the distal end of the needle such that the distal end of the needle is exposed. In the second position, the shield covers the distal end of the needle. The channel guides the protrusion as the shield moves from the first position to the second position. With this arrangement, a shield may be directed to move in a desired path with stability. In addition, the distal end of the needle may be initially exposed to permit visual confirmation of priming, while allowing the shield to cover a majority of the needle to minimize any needle-related anxiety.
