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.

A system for mass vaccination includes a plurality of portable electronic injectors, a mobile process manager and a database. Each portable electronic injector includes at least one needle to administer a measured amount of at least one vaccine to a body skin/tissue and an indicator system to provide an indication when either an injection error occurs or when a vaccination indication is required. The mobile process manager is in wireless communication with the plurality of injection devices and controls a mass vaccination. The process manager transmits task data to all injection devices in parallel via WI-FI, receives the vaccination indications from each injector in real time, also receives injection errors and vaccination process data, alerts a vaccination process overseer generally in real-time of the errors and transmits the injection data from each injector via cellular and/or internet transmission to the database.

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.

An injector (10) for injecting a medicament into a patient. The injector includes a container (18) defining a first chamber (22), which contains a fluid therein, and a second chamber (23). The injector also includes an injection conduit (126) configured for directing the fluid fired from the container into the patient. A transfer mechanism is operable by a user to transfer the fluid from the first chamber to the second chamber in a first stage of operation, and a firing mechanism is operable by the user for firing the fluid from the second chamber through the injection conduit in a second stage of operation. An energy source (62) is in powering association with the firing mechanism to drive firing mechanism in the first and second stages.

A drug delivery device is provided herein, the device including a reservoir for containing a medicament. The medicament includes a suspension of solids in a liquid carrier. The device also includes a needle having a distal end for injection into a patient, a proximal end in communication with the reservoir, and a lumen extending between the distal and proximal ends. A path is defined from the reservoir to the distal end of the needle through the lumen, the path having an inner diameter that decreases in a proximal to distal direction along at least a portion thereof. Advantageously, with the subject invention, a flow path may be defined which provides a more gradual transition in diameter from the reservoir to a distal tip of the needle. In this manner, changes in velocity of the suspension may be less abrupt than in the prior art, thus better maintaining solid particles in the suspension.

The present disclosure relates to a medicament delivery device. The medicament delivery device comprises a housing, a needle and a reservoir. The needle is configured to project from a distal end of the housing. The reservoir is disposed in the housing and has a flexible wall. The medicament delivery device further comprises a dispensing member and a biasing member. The dispensing member is disposed in the housing and the biasing member is configured to bias the dispensing member to move in an arcuate path relative to the housing such that the dispensing member moves across the flexible wall of the reservoir to dispense medicament from the reservoir when the reservoir contains medicament.

A medicament delivery device is presented having a medicament container having an attached medicament delivery member; a housing where the medicament container is movable between a retracted and an extended position in which the medicament delivery member extends from the housing; a drive unit that advances the medicament container from its retracted position to its extended position to expel the contents through the medicament delivery member; and a medicament container holder for carrying the medicament container as it is advanced, the medicament container holder having a proximal end through which the medicament delivery member extends and a holding member releasably connected to the drive unit and attached to the medicament container holder. The holding member has a biasing element having a resilient structure in the form of a tubular wall provided with slots extending in the generally circumferential direction arranged to bias the medicament container in the proximal direction in the medicament container holder.

An injection device includes a carrier, a needle, a driver coupled to the needle, the driver being slidable relative to the carrier between a retracted configuration and a deployed configuration, a shuttle configured to move the driver between the retracted configuration and the deployed configuration, and a stop configured to move from a first configuration to a second configuration, wherein the stop is configured to maintain the driver in the deployed configuration, and movement of the stop from the first configuration to the second configuration allows the shuttle to move the driver from the deployed configuration to the retracted configuration.
