    Abstract: A syringe plunger rod includes a rod body having a proximal rod end and a distal rod end, where the distal rod end has a distal rod end circumference. The syringe plunger rod also includes a threaded extension extending distally from the distal rod end. The threaded extension includes at least one male thread extending from a thread shank, where the thread shank has a proximal thread shank end and a distal thread shank end. The proximal thread shank end has a diameter less than the diameter of the distal rod end circumference. The syringe plunger rod also includes an annular distal rod surface extending between the distal rod end circumference and the proximal male thread shank end.

    Abstract: An injection device includes a drive spring within the housing, a first drive component that transfers drive from the drive spring to a plunger disposed within a medicament container, and a damper concentrically arranged with respect to the first drive component. The damper is longitudinally fixed relative to the housing. The first drive component moves along the longitudinal axis relative to the damper under the influence of the drive spring. The damper frictionally engages a surface of the first drive component during movement of the drive component relative to the damper. A method of manufacturing the injection device is also described.

    Abstract: An infusion set adapter connects to an infusion set for delivering a medicament to an injection site from a medicament source. The infusion set adapter can include a housing a controller, a power source, and at least one sensor configured to detect a characteristic of the infusion set adapter, infusion set, infusion site, and/or the medicament source. The controller can process information received from the one or more sensors and cause an action to occur in response to the received and processed information. The housing can include a retention member to connect the infusion set adapter to the infusion set. An infusion set include components of the infusion adapter above integrated therein. Methods of operating infusion sets and infusion set adapters are also disclosed.

    Abstract: Systems and methods for drug delivery are disclosed in which an injection device comprises a parenteral interface, comprising a support and a needle assembly, suspended within a cavity in a housing of the device such that the parenteral interface is movably mounted with respect to the housing when the needle assembly is in the injection position. The parenteral interface can be configured to allow movement of the housing of the device with respect to the skin without displacing the needle assembly. The devices can be configured to passively or actively compensate for movement of the housing relative to the injection site to ensure correct delivery depth is maintained during time device is worn. For example, by mounting the support of the parenteral interface on a deformable mount or an articulated or rotatable component.

    Abstract: A parenteral injection device comprises a housing defining an internal cavity and an output, a first reservoir disposed within the internal cavity, where the first reservoir defines a first chamber that is configured to store a drug and is in fluid communication with the output, a first drive mechanism to selectively force the drug from the first chamber, and a second reservoir disposed within the internal cavity, wherein the second reservoir defines a second chamber that is configured to store a gas and is in fluid communication with the output. The injection device further comprises a second drive mechanism to selectively force the gas from the second chamber, and a controller in signal communication with the first and second drive mechanisms, such that the controller is configured to selectively direct the first and second drive mechanisms to force the drug and gas from the first and second chambers, respectively, to the output in a predetermined sequence.

    Abstract: A system for manufacturing elastomeric components is provided. The system may include a molding station having a mold configured to receive an elastomeric material, form a pad that includes a plurality of untrimmed elastomeric components, and cure the pad. The system may further include an automated marking station comprising a laser and a camera. The automated marking station may be configured to remove the cured pad from the molding station, present the cured pad to the laser to form a mark on each of the untrimmed elastomeric components, and present the cured pad to the camera to capture an image of each mark. A process for manufacturing the elastomeric components is also provided.

    Abstract: A device and method for measuring a volume of liquid expelled from a syringe is provided. The device generally includes a syringe barrel, a plunger actuated with a plunger rod, and a sensor. The sensor may include two ports with one port being in fluid communication with a source of fluid external to the syringe barrel, while the second port is in fluid communication either with a proximal end portion of the syringe barrel or a hollow plunger rod having a first end closed by the plunger. The method may include expelling liquid from the syringe; detecting and recording differential pressure with the sensor over time; and calculating the volume of liquid expelled from the syringe from the recorded differential pressure over time.
