Abstract: An injection device may include a container, a mobile component, a spring, a sensor, and/or a wireless communication device. The container may have an open proximal end, a substantially closed distal end, and a reservoir including a medicament defined between the open proximal end and the substantially closed distal end. The mobile component may be provided in the container and be movable with respect to the container to cause the medicament to be expelled from the container. The spring may be connected to the mobile component and configured to cause the mobile component to move within the container. The sensor may be connected to an end of the spring and configured to measure a parameter associated with an injection operation of the injection device. The wireless communication device may be configured to communicate, to a computing device, information associated with the injection operation of the injection device.

Abstract: A sensor assembly for an injection device may include a disposable label and/or a reusable housing. The disposable label may be configured to be attached to the injection device and include an electrically conductive trace. A first portion of the electrically conductive trace may be configured to be altered in response to a first operation of the injection device. The reusable housing may be removably connected to the disposable label and include a processor and/or a wireless communication device. The processor may be removably electrically coupled to the electrically conductive trace and configured to be activated in response to an alteration of the first portion of the electrically conductive trace. The wireless communication device may be configured to wirelessly communicate, to a computing device, information associated with the alteration of the first portion of the electrically conductive trace. A system may include the sensor assembly and the injection device.

Abstract: A sensor assembly for an injection device may include a housing and/or a mechanical interface. The housing may include a sensor and/or a wireless communication device. The sensor may be configured to detect a movement of a component of the injection device associated with an injection operation of the injection device. The wireless communication device may be configured to communicate, to a computing device, information associated with the movement of the component of the injection device. The mechanical interface may be configured to attach the housing to an exterior surface of the injection device. A system may include the sensor assembly and the injection device.

Abstract: A needle hub for a drug delivery device includes a hub body, an activation button, a needle holder and a needle attached to the needle holder, a cannula holder and a cannula attached to the catheter holder, a needle actuation mechanism configured to move the needle holder and the cannula holder from a retracted position to an insertion position and configured to move the needle holder back to the retracted position, and a cannula spring biasing the catheter holder to a retracted position. Movement of the activation button is configured to cause the needle holder and the catheter holder to move from the retracted position to the insertion position, with the needle holder configured to return to the retracted position while the catheter holder remains in the insertion position.

Abstract: A needle hub for a drug delivery device includes a hub body, an activation button, a needle holder moveable relative to the hub body, a needle attached to the needle holder, a needle spring biasing the needle holder to a retracted position where the needle is positioned within the hub body, a cannula holder moveable relative to the hub body and the needle holder, a cannula attached to the cannula holder, with the cannula configured to be in fluid communication with a fluid source, and a cannula spring biasing the cannula holder to a retracted position. Movement of a portion of the hub body is configured to disengage a connection between the cannula holder and the hub body to allow the cannula holder to return to the retracted position.

Abstract: A needle hub for a drug delivery device includes a needle holder and a needle attached to the needle holder, a needle actuation assembly configured to move the needle holder from a retracted position, to an insertion position, and back to the retracted position, and a pressure interlock comprising an inlet configured to be in fluid communication with a fluid source, an outlet in fluid communication with the needle, and a lock member. The lock member having a first position where the lock member prevents actuation of the needle actuation assembly and a second position where the lock member allows actuation of the needle actuation assembly. The lock member is moved from the first position to the second position based on a pressure within the pressure interlock.

Abstract: A drug delivery device includes a housing, a fluid reservoir received within the housing, a drive assembly configured to dispense fluid from the fluid reservoir, a needle hub actuator attached to the housing, and a needle hub at least partially received by the housing. The needle hub includes a hub body, a needle holder with a needle attached to the needle holder, and a cannula holder with a cannula attached to the cannula holder. The needle hub actuator is configured to move the needle holder and the cannula holder from a retracted position where the needle and the cannula are positioned within the hub body to an insertion position where the needle and the cannula are positioned within the hub body. The needle hub is detachable from the housing.

Abstract: A needle hub for a drug delivery device includes an applicator having a needle holder, a needle attached to the needle holder, a needle retraction spring, and an activation button, and a hub body including a cannula holder, a cannula attached to the cannula holder, a cannula withdrawal button, and a cannula retraction spring. At least a portion of the hub body is configured to be received within the applicator, with the applicator configured to be separated from the hub body. Movement of the activation button is configured to move the needle holder and the cannula holder from a retracted position to an insertion position. The cannula withdrawal button locks the cannula holder in the insertion position against a biasing force of the cannula retraction spring when the cannula holder is moved from the retracted position to the insertion position.

Abstract: A system for connecting a reservoir and a container comprising, at the container level, a container opening; container closing means; and container locking means arranged to lock the container closing means in the closed position and comprising, at the reservoir level, a reservoir opening; reservoir closing means; actuation means arranged to actuate the container locking means when the container is connected to the reservoir to release the container closing means; and reservoir locking means arranged to lock said actuation means and arranged to be actuated by additional actuation means to release said actuation means connected to the reservoir, the reservoir locking means and/or said actuation means being arranged to lock the reservoir closing means in a closed position.
