  • Patent number: 10653851
    Abstract: Described is an autoinjector comprising a case, a chassis slidably arranged in the case, a syringe carrier operably coupled to the chassis, an outer plunger selectively engaged to the chassis, an inner plunger selectively engaged to the outer plunger, and a drive spring applying a biasing force to the outer plunger. The biasing force is applied to the inner plunger when the inner plunger is engaged to the outer plunger. Rotation of the chassis causes the inner plunger to rotate relative to the outer plunger and disengage the outer plunger to remove the biasing force from the drive spring on the inner plunger. When the inner plunger disengages the outer plunger, the biasing force of the drive spring pushes the chassis to retract the syringe carrier relative to the case.

  • Patent number: 10657403
    Abstract: A data collection device includes a camera and a processing arrangement configured to capture at least two images of a medicament dose indicator of a medicament delivery device in each of the at least two images the processing arrangement identifies a displayed dosage using a first character identification technique, in each of the at least two images, determines whether the displayed dosages in the images are different and, if not, identifies at least one character in the images using a second character identification technique and determines the medicament dosage amount indicated by the medicament dose indicator based thereon. The first character recognition technique may be, for example, an optical pattern recognition or correlation, may be less computationally intensive than the second character recognition technique, for example, an optical character recognition (OCR). In another embodiment, the first and second character recognition techniques are different OCR processes.

  • Patent number: 10653844
    Abstract: An auto-injector for delivering a liquid medicament includes a housing arranged to contain a syringe with a piston for sealing the syringe and displacing the medicament, the housing having a proximal end and a distal end and a telescopic plunger unit arranged between the piston and the proximal end of the housing, the telescopic plunger unit comprising a telescopic frame and a spring element surrounding a plunger element. The plunger element is fixed to a base of the telescopic plunger unit and the spring element is held in an initial compressed state by a compressive force exerted by the base of the telescopic plunger unit. When the spring element is released, a tapering profile of the telescopic frame is configured to provide varying friction with extension such that resistance to telescopic extension decreases as spring force provided by the spring element decreases with increasing extension of the telescopic plunger unit.

  • Patent number: 10653841
    Abstract: A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.
