An actuating device having integrated plunger is configured to be removably mounted to an automatic mixing device for a syringe. The actuating device includes lower and upper housings, a trigger member, a lockout ring, a mixing biasing member, a delivery plunger, a plunger biasing member, and a mixing plunger. The mixing plunger is releasably engaged with the trigger member in an initially locked state and engageable with at least one seal of the mixing device. The trigger member is operable to initiate decompression of the mixing biasing member and engagement of the mixing plunger with the at least one seal of the mixing device. The delivery plunger may also be activated to expand from a first, collapsed configuration to a second, expanded configuration by actuation of the trigger member.

A power pack for use with a medicament delivery device is presented having a plunger rod movable along a longitudinal axis; a drive spring operably connected to said plunger rod; a plunger rod sleeve arranged with holding elements for releasably holding said plunger rod with said drive spring in a tensioned state. Signal initiating elements are arranged to said plunger rod; and signal generating elements arranged to cooperate with said signal initiating elements for providing information to a user of a medicament delivery device about the movement of said plunger rod when said plunger rod sleeve has been activated to release said holding elements.

A pen cap for a medication delivery pen includes a piston-style detector mechanism. The piston-style detector mechanism includes at least an inner shell having first open end through which the medication delivery pen can be inserted, a second end opposite the first end, a sidewall defined by an outer surface and an opposing inner surface, and a passageway extending from the outer surface to the inner surface. The sidewall extends between the first end and the second end thereby defining a pen-receiving cavity there between. The piston-style detector mechanism further includes at least one switch and a translatable shaft at least partially disposed in the passage. The translatable shaft includes a body that extends at least from a pen-interfacing portion in the pen-receiving cavity to a switch-interfacing portion thereof. The translatable shaft is oriented to travel from a first location to at least a second location during capping of a medical delivery pen into the inner shell to toggle the at least one switch.

One or more embodiments relate, generally, to a reusable accessory for a medication injection pen. Such a reusable accessory may be adapted to be reversibly attached to a medication injection pen, and configured to detect an event associated with an injection of medication from the medication injection pen. It may also be configured to determine a percentage of medication that remains active for injection by the medication injection pen based on timing information and dosing event information.

One or more embodiments of the disclosure are related, generally, to a reusable accessory for a manual medication delivery device. Such a reusable accessory may include a wireless communication interface, a detection circuitry, and a recommendation system. In one or more embodiments, an adapter may be configured to reversibly couple such a reusable accessory to a manual medication delivery device. Dosing events may be detected that are associated with dosing at the manual medication delivery device. Dose recommendations may be provided responsive to analyte measurements and/or dosing events.

The present disclosure relates to an administration mechanism for a medicament delivery device having a movable sleeve, and a delivery member cover having a distal end portion configured to receive the movable sleeve. The delivery member being configured to be linearly displaceable between a first position and a second position relative to the movable sleeve, wherein the distal end portion has an end face defining a guide surface and the movable sleeve has a radially outwards extending first follower structure configured to cooperate with the guide surface when the delivery member cover is moved from the first position towards the second position, causing the movable sleeve to rotate.

A monitoring feature, such as, for example, a pen cap, for an insulin delivery device may include at least one circuit adapted to detect at least one of a capping or decapping of the pen cap from an insulin pen and a processor for using information to the at least one of a capping or decapping of the pen cap. A monitoring feature for an insulin delivery device includes at least one circuit adapted to detect use of the insulin delivery device.

One or more embodiments relate, generally, to a reusable accessory for a medication injection pen. Such a reusable accessory may be adapted to be reversibly attached to a medication injection pen, and configured to detect an event associated with an injection of medication from the medication injection pen. It may also be configured to determine a percentage of medication that remains active for injection by the medication injection pen based on timing information and dosing event information.

A portable auto-injector configured to store a dry medication separately from a liquid component, wherein removal of a cap operates a first actuation mechanism which opens a valve between a first and second chamber that are slidably movable relative to each other and thus allows for the initiation of a mixing step prior to injection. An extendable needle guard is provided over the delivery assembly which prevents premature injection as well as inadvertent sticks or other cross contamination of a needle. The needle guard can also form part of a secondary trigger mechanism which injects the mixed components after the mixing stage is complete.

The present disclosure relates to an administration mechanism for a medicament delivery device having a movable sleeve, and a delivery member cover having a distal end portion configured to receive the movable sleeve. The delivery member being configured to be linearly displaceable between a first position and a second position relative to the movable sleeve, wherein the distal end portion has an end face defining a guide surface and the movable sleeve has a radially outwards extending first follower structure configured to cooperate with the guide surface when the delivery member cover is moved from the first position towards the second position, causing the movable sleeve to rotate.
