Injection device for dispensing a medicament, comprising: a cartridge module, a dispensing mechanism which is actuated to dispense the injectable preparation, a dose-setting mechanism for setting the dose at which the injectable preparation is dispensed when the dispensing mechanism is actuated, the dose-setting mechanism comprising: a housing part (11) in which at least part of the dispensing mechanism is received, a display sleeve (13) rotatable therein, and an insertion sleeve (15) that can be inserted into the housing part (11), wherein the insertion sleeve (15) has, on its outer face, a raised surface section (20) that is transparent at least in some areas, and the housing part (11) has a recess (25) which is open at its distal edge (24) and which receives the insertion sleeve (15) in a rotationally fixed manner from the direction of the open end of the recess (25),
and insertion sleeve for an injection device, dose-setting mechanism for an injection device for dispensing a medicament, and method for assembling an injection device.

A drive mechanism for a delivery device is presented. The drive mechanism comprises a housing (24) and a piston rod (6) having a longitudinal axis (x) and a piston rod feature (17). The drive mechanism further comprises a drive member (1) being movable with respect to the housing (24). The drive member (1) comprises a drive feature (15). The drive feature (15) is selectively engageable with the piston rod feature (17) by the radial displacement of the drive member (1) with respect to the piston rod (6). When the drive member (1) is in the first position, the drive member (1) is disengaged from the piston rod (6), and when the drive member (1) is in the second position, the drive feature (15) is engaged with the piston rod feature (17). When the drive member (1) moves distally with respect to the housing (24), said distal movement is transferred to the piston rod (6) such that the piston rod (6) moves distally with respect to the housing (24).

Embodiments of the invention include a medicament device configured to provide stepwise instructions for using the device to a user in a particular sequence is provided. The device includes a device housing configured to receive a container, the housing including a control interface, the control interface including at least one responsive member reactive to a user input, an actuation mechanism configured to interact with the container, a signal output component associated with the device housing, and circuitry associated with the device housing configured to control a provision of the stepwise instructions to the user in the particular sequence. The container includes a first housing for containing a medicament, a second housing, and an injection member, wherein the first and second housings are movable relative to one another. The container further includes an injection member which is retractable within the second housing to prevent an unintentional contact with the injection member.

An apparatus includes a syringe housing and a plunger slidably received within the syringe housing. A plunger magnet is secured to the plunger. A potentiometer housing is fixed to the syringe housing and includes a potentiometer disposed therein. A wiper magnet is also disposed within the potentiometer housing. Movement of the plunger magnet causes a corresponding movement of the wiper magnet.

A device for monitoring a manually operated syringe that according to one embodiment includes a basis which is adapted to be connected to a medication administration point of a patient and comprises a syringe insertion port to receive the syringe dispensing tip, the basis being configured such that when the syringe is inserted in the insertion port the syringe barrel is not in direct contact with the basis, and at least part of the syringe barrel projects from the basis in the direction of the barrel axis, and further comprising an image acquisition system arranged on the basis and adapted to capture an image of at least part of the syringe plunger when the syringe is inserted in the insertion port.

An incremental syringe useful for multiple injections of medications like botulinum toxin is provided. The syringe includes detents on the syringe plunger which provide a tactile feeling, a discrete audible sound or click, or preferably both, for every unit of medication aspirated or injected to or from an individual syringe. Hence, there is no need to look at the syringe, or bring it to the eye level, during use thereof. In some embodiments, a second set of detents is included, and in some embodiments a third set of detents is included. Syringe plungers useful for combining with a syringe body to produce such an incremental syringe are also described.

A plunger head to measure fluid in a drug cartridge includes a transducer coupled to emit ultrasonic signals, and a power source. A controller is coupled to the transducer and the power source, and the controller includes logic that when executed by the controller causes the plunger head to perform operations. For example the plunger head may emit the ultrasonic signals along a length of the drug cartridge, when the plunger head is disposed in the drug cartridge, and receive the ultrasonic signals after the ultrasonic signals are reflected from a dispensing end of the drug cartridge. The plunger head may then determine when the ultrasonic signals received by the transducer have an absolute value of amplitude greater than a first threshold value, and associate a timestamp with the ultrasonic signals received that have the absolute value of amplitude greater than the first threshold value.

An assembly for a drug delivery device and an associated drug delivery device are provided. The device has a drug delivery device housing and a medicament contained in the drug delivery device housing. A clutch is established between the dose knob and the dial link to prevent inadvertent proximal axial movement of the lead screw away from the cartridge piston, which can lead to dosing inaccuracies.

A kit is disclosed for accurately loading a small volume dose of a medication within a syringe and for delivering the small volume dose of the medication at a treatment site. The kit generally includes a loading and delivery system in accordance herewith, a syringe, and a medication. The loading and delivery system includes a syringe delivery ring and a syringe loading guide, which may be used for example, to administer a small volume dose of a medication at the end of an ocular surgery.

A syringe device for ejecting a dose of a medicament, the syringe device comprising: a dose limiting mechanism arranged to interact with a dose ejecting mechanism to prevent ejection of a dose exceeding a set dose, and a safety mechanism, which is arranged such with respect to the dose ejecting mechanism that, if the dose limiting mechanism fails, the safety mechanism prevents ejection of a dose exceeding the set dose.
