摘要： 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.

摘要： A container for storing a pharmaceutical composition includes a body portion having an elastomeric material, and an inner lining having a thermoplastic material covering at least a portion of an inner surface of the body portion. The container forms an internal chamber for storing the pharmaceutical composition, where the internal chamber is bounded by the inner surface of the body portion. The inner lining provides a barrier between the elastomeric material and the pharmaceutical composition, thus protecting the pharmaceutical composition. Associated methods of storing the pharmaceutical composition within the container, as well as manufacturing the container, are also described.

摘要： An injection system, including an injector having a dispensing mechanism configured to dispense a medicament, and a ready-to-use indicator. The ready-to-use indicator includes a controller configured to interact with the ready-to-use indicator and an audio and/or visual indicator, a temperature sensor, and a temperature analog having similar thermodynamic properties of the medicament. The temperature sensor is configured to detect a temperature of the temperature analog which represents the dynamic temperature of medicament as the medicament is heated or cooled. The temperature sensor is configured to communicate the detected temperature to the controller and to alert the controller when a preset temperature is reached. The ready-to-use indicator is configured to alert a user when the preset temperature is reached, signifying the medicament is thermally ready to be delivered by the dispensing mechanism. The audio and/or visual indicator is configured to display indicate one or more notifications to the user.

摘要： 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.

摘要： 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.

摘要： A method of manufacturing a medical component includes molding a first member of the medical component from an elastomeric material. The first member includes a first end defined by a closed base wall, an opposing second end which is an open end, a sidewall extending between the first and second ends, and an internal recess to receive at least one electronic device. The method further includes positioning the electronic device within the recess of the first member to form an assembly, such that the electronic device is received in an inverted open cavity defined by the sidewall. The method further includes applying a protective film on the second end of the first member, such that the protective film covers an exposed surface of the electronic device. In addition, the method includes overmolding the assembly with the elastomeric material to form the medical component having the electronic device embedded therein.

摘要： 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.

摘要： 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.

摘要： A medication administering device includes upper and lower housings. The lower housing supports a syringe having a needle. A needle guard is in sliding engagement with the lower housing and is proximally movable from a first position, wherein the needle guard conceals a tip of the needle, to a second position, wherein the needle guard exposes the tip of the needle. The upper housing is configured to receive a distally directed force and move relative to the lower housing from a pre-use position to a dispensed position in response to the manual force. When the upper housing is in the pre-use position and the needle guard is in the first position, the upper housing cannot move toward the dispensed position. Proximal movement of the needle guard from the first position to the second position frees the upper housing for movement to the dispensed position in response to the force.
