An injection device comprising a housing having a longitudinal axis, a dose selector (16) capable of being rotated about said longitudinal axis with respect to said housing by a user to set a dose of medicament to be ejected from the injection device and a spring (20) capable of storing energy necessary for ejecting the dose of medicament from the injection device. The spring is coupled to the dose selector such that a charging force can be transferred from the dose selector to the spring to increase the energy stored by the spring. The injection device further comprises a ratchet arrangement (25) moveable between an engaged state in which the spring is limited from unwinding from a currently selected dose and a disengaged state in which the spring is able to unwind and a drive assembly including a plunger element (23) capable of providing an axial force for ejecting a dose of medicament from the injection device. The drive assembly further comprises a drive clutch (21) moveable from a disengaged state in which a force path from the spring to the plunger element is interrupted and an engaged state in which the drive assembly can provide the axial force for ejecting a dose of medicament from the injection device via said force path.

An assembly for a drug delivery device comprises: a housing having a proximal end and a distal end, a dose setting and drive mechanism comprising a dose setting member moveable relative to the housing in a dose setting operation from an initial position to a dose set position, the dose setting and drive mechanism further comprising a piston rod displaceable in the distal direction relative to the housing in a dose delivery operation, wherein, during the dose delivery operation, the piston rod is displaced relative to the housing by a displacement distance which is determined by the set dose, a guide track, a tracking member configured to cooperate with the guide track, and a coupling mechanism configured to operatively couple the tracking member to the dose setting and drive mechanism, wherein the coupling mechanism has a coupled state and a non-coupled state.

A delivery system includes a cartridge storing a liquid, and a dosing mechanism being configured to connect to the cartridge and to dispense a predetermined amount of liquid from the cartridge. The cartridge is non-reversibly transformable from a filling configuration, in which liquid can be drawn into the cartridge, to a dispensing configuration, in which liquid can only be dispensed from the cartridge

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.

Multi-dose dispenser comprising: a product reservoir (14), on the X-axis, opening at a distal end through an outlet orifice and comprising a barrel (24); a piston (20) comprising a piston rod (38) having a rack and, at a distal end of the piston rod, a piston head (34) slidably mounted in the barrel (24) along the X-axis; a pawl mounted so as to be movable along the X-axis relative to the reservoir and configured to cooperate with the rack so as to drive the piston along the X-axis only in a forward direction of the piston in the barrel; a spring arranged to push the pawl back along the X-axis in a reverse direction; a case containing the pawl and at least a part of the piston; and a check valve arranged to seal the outlet orifice and allow only an outlet of product from the reservoir.

The present disclosure is directed to a dose setting mechanism that may be used with a drug delivery device. The dose setting mechanism may include an inner body having a helical thread along an outer cylindrical surface of the inner body, and a drive sleeve for driving a piston rod in an axial direction, the drive sleeve positioned within at least a portion of the inner body. The dose setting mechanism may further include a dose dial sleeve rotatably engaged with the helical thread of the inner body and a dial grip connected to the dose dial sleeve and releasably connected to the drive sleeve. Further when a dose is set, the dial grip is rotated so that both the dose dial sleeve and the drive sleeve rotate with respect to the inner body.

Dose detection systems for medication delivery devices are described. One is a module for removable attachment to a dose button of a medication delivery device. A device with a dose detection system is also disclosed. The module includes a processor and at least one measurement sensor operably coupled to the processor and configured to detect the positon of a sensed component within the delivery device. Medication identification system may also be provided with an identification sensor and a light guide member.

An injector comprising: (a) a housing; (b) a control releasably secured to the housing; and (c) a syringe movably positioned within the housing, wherein when released, the control drives the syringe to expose a portion of the syringe outside of the housing.

A portable medical device for injecting a medicament into a patient. The device includes a control circuit with a memory, the control circuit automatically storing in the memory an ejection event including an amount of the medicament that is ejected from the portable medical device during the ejection event; and a proximity sensor configured to sense proximity of a solid object located in an ejection direction of the portable medical device without making contact with the solid object. The control circuit is configured to tag the ejection event as an injection event if the ejection takes place in proximity of the solid object and to tag the ejection event as a priming ejection if the ejection does not take place in proximity of the solid object.

An injector for delivering liquid can include a body having a proximal end, a distal end, a longitudinal axis, and a track follower adjacent to the proximal end. A plunger can be disposed at least partially within the body and movable with respect to the body along the longitudinal axis. An actuator can be positioned at the proximal end of the body and operably connected to the plunger. The actuator can include a track having a first portion and a second portion. The first portion can limit travel of the actuator along the longitudinal axis to deliver a first predetermined amount of the liquid. The second portion can limit travel of the actuator along the longitudinal axis to deliver a second predetermined amount of the liquid. The actuator can be positionable to selectively control displacement of the plunger pursuant to the first portion or the second portion of the track.
