Abstract: Drug-delivery systems configured to generate indications regarding a user's level of skill, familiarity, or experience with operating such systems are described. The systems may comprise a syringe assembly, one or more skin contact sensors, and one or more syringe assembly sensors configured to detect initiation and/or completion of a dispensing event. The system may further comprise one or more processing circuits configured to measure a time duration between when the skin contact sensor(s) detect contact with skin tissue and when the syringe assembly initiates a dispensing event, compare the measured duration against a threshold time duration, and generate a user indication signal if the measured duration exceeds the threshold time duration.

Abstract: Methods and systems are provided for evaluating injection sites on a body of a patient. The methods/systems may instruct a patient to place one or more capacitance sensors in contact with a potential injection site on the body of the patient. The methods/systems may also comprise using a processing circuit to receive data indicative of a capacitance of body tissue at the potential injection site, as measured by the one or more capacitance sensors. The methods/systems may also comprise generating, using the processing circuit, an indication of a level of pain that would be expected to be experienced by the patient from a potential injection at the potential injection site based on the received capacitance.

Abstract: An injection device may include a housing and a baseplate coupled to the housing. The baseplate may include a flange portion and an axial portion that extends from the flange portion in a longitudinal direction of the housing. The baseplate may be an opaque, polymer material that is more thermally conductive than a material of the housing. The injection device may additionally include a syringe at least partially disposed within the housing. The syringe may include a needle. The injection device may include a deployment mechanism configured to move the syringe relative to the housing from a retracted position to a deployed position in which the needle projects beyond the baseplate. At least a portion of the syringe may be visible when the syringe is in the retracted position.

Abstract: The present disclosure relates to drug delivery devices, and in particular, to drug delivery devices configured to reconstitute a lyophilized drug powder into liquid form prior to delivery into a patients body. In some embodiments, such devices include a flexible drug reservoir having a proximal reservoir component storing a liquid diluent and a distal reservoir component storing a lyophilized drug powder, wherein the two compartments are separated by a frangible seal. A compression member may be positioned above the reservoir and held up by a releasable mechanism. When released, the compression member may be driven downwards to compress the proximal compartment so as to break the frangible seal and allow the diluent to mix with the drug powder and form a liquid drug mixture, and then to eject the liquid drug mixture from the reservoir.
