User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen.

Pen needle attachment mechanisms

A disposable pen needle, comprising a hub having a needle situated thereon having a patient end and a non-patient end, a removable patient end cap attached at the distal end of the hub, a removable non-patient end cap attached at the proximal end of the hub, wherein greater force is required to detach the patient end cap than is required to detach the non-patient end cap.

Pen needle packaging

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.

Pen needle assembly

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen. Embodiments include a needle-bearing hub includes a circumferentially oriented flexible tab that engages a radially inward rib on an outer cover to assist in attaching a pen device to the pen needle.

A pen needle is provided with a plastic non-patient end. Since the non-patient end needle does not contact the patient, the needle can be formed with a larger diameter, permitting more secure attachment to a medication pen and greater medication flow from the cartridge through the cannula. In addition, a two-part hub construction comprising a needle bearing sub assembly and an adapter for attachment to the pen body may be used to lower materials volume and costs, and reduce sharps disposal. In embodiments, a hub according to the invention may be provided with a shield that provides an audible and/or tactile indication when full penetration depth of the needle is achieved. Windows on the shield may reveal a color band on the hub at the full-penetration depth position to provide the user with a visual indication that the pen needle has been used.

Pen needle packaging concepts provide sterile packaging which can be made with fewer small parts and which can be opened with one hand, streamlining the process of installing the pen needle on the medication pen. In some instances, the packaging operates as a sharps container to store the pen needle after use.

A medical fluid communication system is disclosed comprising a pump controller and a fluid detector. The fluid detector detects characteristics of the fluid and provides fluid measurements to the pump controller, which detects if the fluid is flowing in the medication delivery system. In the event fluid is not flowing due to an occlusion, the pump controller may attempt to resolve the occlusion or may provide a warning to a user that an occlusion is occurring.

System and method for detecting occlusions in a medication infusion system using pulsewise pressure signals

A shielded pen needle assembly is provided in which the hub extends distally beyond an outer sleeve of the assembly.

Extended hub for a safety pen needle

A pre-filled, single-use injection device includes a passive dual shield on the patient end of the needle. The device is self-contained so that the entire needle is shielded after use without a separate passive shield system for the non-patient end.
