A syringe holder includes a syringe barrel holder having a depression which is configured to receive and engage finger tabs of a syringe and has a bottom depression surface engageable by the finger tabs. A barrel opening receives a barrel of the syringe, and includes a central longitudinal axis, a shaft channel and a set screw channel having a screw axis passing through the shaft channel. A dosing shaft extends from a first end to a second end and includes a plurality of notches between the ends. The dosing shaft is located and slideable within the shaft channel. A plunger cap includes a plunger receptacle and attaches to a first end of the dosing shaft. A socket set screw is located and engaged within the set screw channel and has a resilient end engageable with the notches of the dosing shaft.

Electronic modules for attachment to a drug delivery device include delivery status sensing means (21, 22) for monitoring a delivery status of the device, a status indicator (25) with an indicator element controllable to indicate a delivery or module status, and a status indicator controller (23), which generates an indicator control signal on behalf of the status indicator element, which in turn produces a status signal. The indicator control signal has an amplitude varying monotonically in time between a minimum value and a maximum value in a first interval of a base cycle, and between the maximum value and the minimum value in a second interval of the base cycle. In at least one of the first and the second interval, the mean value of the indicator control signal is below the average of the maximum and the minimum values of the indicator control signal to realize increased energy savings.

Drive systems for a drug delivery device are provided. The drive systems can be positioned within a container that stores a liquid drug to be delivered to a user. The drive systems can be coupled to a plunger positioned within the container. The drive systems can be incrementally advanced to drive the plunger further into the container, thereby expelling a portion of the stored liquid drug from the container for delivery to the user. The container can be any type of container including a pre-filled, standardized drug cartridge. The drive systems and container can be components of a wearable drug delivery device.

A supplementary device for a manually operable injection device, the supplementary device including a body having at least one engaging member to releasably mount the body to the injection device in a specific position on an outside surface of the injection device, and at least one indicator located on the body and having a shape or contour to overlap or to align with a mark on the outside surface of the injection device when the body is in or near the specific position.

A button-activated medicament delivery device is presented having a housing arranged to house a medicament container, a vibration sensor configured to measure vibrations induced by the button-activated medicament delivery device during a medicament delivery, a button arranged to initiate medicament delivery from the medicament container, and to activate the vibration sensor when initiating the medicament delivery, and processing circuitry configured to obtain a vibration measurement from the vibration sensor and to compare the vibration measurement with a reference vibration measurement characteristic for the button-activated medicament delivery device during medicament delivery. The processing circuitry is configured to generate a time of measurement of the vibration measurement in case the vibration measurement matches the reference vibration measurement.

A device for delivering a number of predetermined amounts of medicament includes a body having proximal and opposite distal ends, extending along a longitudinal axis, and configured to hold a medicament container; a driver in the body configured to act on a held container; a manually movable activation member arranged on the distal end; a biased actuator member movable by the activation member along the longitudinal axis and configured to protrude a distance from a distal end of the activation member and to interact with the driver when the actuator member is moved the distance toward the proximal end for delivering a predetermined amount; and an actuator guide member arranged in the body and configured to interact with the activation member and actuator member such that the guide member is held in a position in the body and released from the position after a predetermined amount of medicament is delivered.

A device (1) for monitoring the state of an injection applicator comprising an energy source (10) and the following electronic components: an accelerometer (5), a time measuring means (6), a temperature measuring means (7), a processing unit (8) connected to a system adapted to store, process and transfer data, said system including: the time measuring means (6), the accelerometer (5), the temperature measuring means (7) and a memory (9), a user interface (4) connected to the processing unit (8) for presenting information based on the data transferred by the processing unit (8), said monitoring device (1) being connected to a control member (3) of the applicator, and wherein said monitoring device (1) is adapted to operate in a sleep mode and in an active mode, and is further adapted to detect by means of the accelerometer (5) at least a first action and a second action, the first action being related to taking said monitoring device (1) out of the sleep mode and putting it into the active mode, and the second action being related to the setting and/or the delivering of a dose.
