The present specification relates to a plunger configured to transmit a force from an energy source to a piston of a primary container, the plunger comprising a plunger rod configured to be subjected to the force from the energy source, the plunger rod having an inner surface forming a cavity, wherein a support element adapted to constrain the energy source within the cavity protrudes radially inwards from the inner surface into the cavity.

A drug delivery device configured to provide a dose of medicament is disclosed. The drug delivery device includes a main housing, a syringe arranged in the main housing, and a pneumatic power pack arranged in the main housing. The pneumatic power pack includes a pressurized gas source storing pressurized gas, a valve for the pressurized gas source, a sleeve having an inner wall, and a plunger. The sleeve is configured to receive pressurized gas released from the pressurized gas source. The plunger is in sliding gas-tight engagement with the inner wall of the sleeve. Upon activation of the valve, the valve releases the pressurized gas, and the released pressurized gas flows into the sleeve and propels the plunger in a distal direction with respect to the sleeve and the syringe, so as to eject medicament from the syringe.

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

AUTO-INJECTOR ASSEMBLY The auto-injector assembly (100) includes a housing (102), a syringe assembly (202) to store a predetermined volume of a drug to be administered, a needle guard (212) to surround the syringe assembly (202) such that a portion of the needle guard (212) is adapted to extend out of the housing (102) in an initial state and to retract into the housing (102) when the portion is pressed on to an injection site, a spring holder (218) to hold a dose delivery spring (216) in a compressed state, locking unit (220) to keep the spring holder (218) in a locked state, and a plunger (222) engaged with the spring holder (218) and adapted to move towards the syringe assembly (202) when the spring holder (218) is unlocked. A position of engagement of the plunger 222) with the spring holder (218) is adapted to change for controlling a travelling distance of the plunger (222) within the housing (102) based on the predetermined volume of the drug in the syringe assembly (202).

A needleless injector includes an injector main body, a housing part including an accommodating space in which an injection substance is accommodated, the housing part defining a flow path to enable the injection substance to be ejected to a target region through an ejection port, and an attachment part configured to attach the housing part to the injector main body. The attachment part attaches the housing part to the injector main body, with a distal end side outer surface of the housing part corresponding to an inner surface of the housing part on a distal end side, where a communication portion where the flow path is in communication with the accommodating space is located, pressed in a direction opposite to a movement direction of a pressurizing unit that pressurizes the injection substance toward the ejection port.

Syringe shield for using a syringe that includes a barrel, a tip and a plunger when manipulating a radioactive solution. The syringe shield includes: a shield body in which the syringe is insertable, the shield body having a window; a first flange at a first open end of the syringe shield; a second flange at a second open end of the syringe shield; wherein the second flange, the shield body, and the window include radiation shielding material, and wherein the tip of the syringe is accessible by the second open end of the syringe shield and the plunger extends outside the first open end when the syringe is inserted in the syringe shield.

A medication injection method where a dose set knob of a medication injection pen is rotated with respect to the housing of the medication injection pen during dose setting and dose correcting, a driver is selectively engages with the dose set knob, the driver being rotatably fixed with respect to the housing during dose setting and dose correcting, the driver is moved axially with the dose set knob during the dose setting and the dose correcting, and the driver is rotated with the dose set knob during an injection.

A drug injection device includes a housing with a cartridge having a predetermined drug volume, a dose setting mechanism for setting a drug dose, and a dose delivery mechanism. A dose setting service element rotates about a longitudinal axis during the drug dose setting. The dose setting mechanism has a last dose setting device to prevent setting of a drug dose greater than the drug volume remaining in the cartridge. The last dose setting device includes a pinion coaxial with the longitudinal axis that rotates about the longitudinal axis with the dose setting service element during drug dose setting, and a rack engaged with the pinion that moves parallel to the longitudinal axis when the pinion rotates. The pinion and the rack have mutual abutment elements that prevent further rotation of the pinion after the rack has travelled an axial length correlated to the predetermined drug volume.

A dispensing mechanism for delivering a dosage of medicament including a housing, a push button, a crank arm that is slideably engageable with the push button, a ram, and a ratchet gear releasably engageable with the crank arm and ram, translation of the push button along an axis causing the crank arm to engage and rotate the ratchet gear which causes the ram to distally advance relative to the housing.

Embodiments relate to using sensor data and location data from a device to generate augmented reality images. A mobile device pose can be determined (a geographic position, direction and a three dimensional orientation of the device) within a location. A type of destination in the location can be identified and multiple destinations can be identified, with the mobile device receiving queue information about the identified destinations from a server. A first image can be captured. Based on the queue information, one of the identified destinations can be selected. The geographic position of each identified destination can be identified, and these positions can be combined with the mobile device pose to generate a second image. Finally, an augmented reality image can be generated by combining the first image and the second image, the augmented reality image identifying the selected one destination.
