A drive mechanism for a medication delivery device containing a resilient member and having a rotation member configured to be rotated in a first direction during setting of a dose of a medication and to be rotated in a second direction during delivery of the dose, where the rotation member is coupled to a drive member that is coupled to a piston rod such that on dose delivery the piston rod is displaced in a distal direction to dispense a medicament and where the resilient member prevents movement of the drive member and the piston rod during dose setting.

An illustrated view of an exemplary emergency kit for use in an emergency medical condition and a method for automating the ordering of the emergency kits for dentist is presented. The emergency kit is useful for providing short-term medical relief in an emergency while waiting for ambulance or other emergency medical personnel to arrive at the scene. The emergency kit provides a useful medical syringe for use by a dentist in a mouth of a patient experiencing an emergency medical condition.

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.

The present disclosure relates to a drive mechanism which is suitable for an injection device, especially a drug delivery device. The mechanism comprises a housing having a longitudinal axis defined by a compartment for receiving a cartridge, a plunger suitable for acting on a bung of a cartridge retained in the housing, a strained pressure spring arranged between the housing and the plunger, a retaining member coupled to the plunger, and a release member operable between a first state, in which the release member constrains the retaining member to the housing, and a second state, in which the release member is movable relative to the housing.

The present disclosure relates to a medicament delivery device comprising: a reservoir for medicament; a dispensing mechanism operable to dispense medicament from the reservoir, the dispensing mechanism comprising a sleeve configured to rotate during the dispensing of medicament and having a plurality of formations at an end of the sleeve; and a dosage measurement system comprising at least one mechanically actuated sensor configured such that, in use, rotation of the sleeve causes successive formations to engage the sensor such that the sensor detects rotation of the sleeve and a processor configured to determine a dosage dispensed from the medicament reservoir based on the detected rotation of the sleeve.

A drug delivery device for sequentially delivering a predefined plurality of fixed doses, wherein the drug delivery device comprises a housing assembly, a drive mechanism comprising a drive tube and adapted to sequentially deliver the predefined plurality of doses, and an activation mechanism for activating the drive mechanism. The drive mechanism further comprises a pre-strained torsional drive spring (108, 208) conserving an initial amount of energy, and adapted for rotating the drive tube, wherein each activation of the drive mechanism, and completion of a drive tube dose sequence reduces the amount of conserved energy in the drive spring, and wherein the initial amount of conserved energy, which is the conserved energy before the first activation, is sufficient to deliver the predefined plurality of fixed doses.

Medication delivery devices are provided having a housing comprising a reservoir sized sufficiently to hold medication, a dose button being rotatable relative to the housing to select a dose size of the medication for an injection, a printed circuit board, a switch mounted to the printed circuit board, and a controller in communication with the switch. The controller is configured to generate a first count of a set of signals using a first counting technique, generate a second count of the set of signals using a second counting technique, and determine, based on the first and second count, reliability data of the first and/or second count. The controller can connect, using a wireless communication module, to a remote computing device to wirelessly communicate with the remote computing device over an unencrypted wireless communication channel, and transmit, using the wireless communication module, encrypted data to the remote computing device.

An arrangement for a drug delivery device is provided, the arrangement comprising: a housing having a proximal end and a distal end, a dose setting member which is rotatable relative to the housing for a dose setting operation in order to set a dose of drug to be delivered, a tracking member, and a guide track. Wherein the tracking member is operatively coupled or coupleable to the dose setting member, or wherein b) the dose setting member is a tracking member. The guide track is configured to form a guiding interface to guide and/or drive movement of the tracking member. The tracking member can be displaced towards an axial tracking member end position during the dose setting operation, wherein the distance by which the tracking member is displaced towards the axial tracking member end position depends on the size of the set dose.

The present disclosure relates to a dosing mechanism for a drug delivery device for selecting and dispensing a number of user-variable doses of a medicament. The dosing mechanism comprises a housing, a piston rod, and a driving mechanism for rotating the piston rod and/or a movement application component, which is directly engaged with the piston rod, in a dispense rotational direction with respect to the housing for dose dispense. The dosing mechanism further comprises a rotational end stop mechanism for terminating dose dispense with a first engagement means, which is rotationally fixed with respect to the piston rod and/or the movement application component, and a second engagement means, which is prevented from rotation with respect to the housing in the dispense rotational direction at an end of dose dispense. In order to improve the dose delivery accuracy, the second engagement means directly engages the first engagement means. disclosure

Provided is a dosage adjuster for a syringe including: a dosage setting part configured to set the amount of dosage usable out of a liquid medicine filled in the syringe; and a setting restriction part configured to switch between a restricted state in which change in setting of the amount of dosage set by the dosage setting part is restricted and a permissible state in which the change in the setting of the amount of dosage by the dosage setting part is permissible.
