Abstract: Drive systems for a drug delivery device are provided. The drive systems can be positioned within a container that stores a liquid drug to be delivered to a user. The drive systems can be coupled to a plunger positioned within the container. The drive systems can be incrementally advanced to drive the plunger further into the container, thereby expelling a portion of the stored liquid drug from the container for delivery to the user. The container can be any type of container including a pre-filled, standardized drug cartridge. The drive systems and container can be components of a wearable drug delivery device.

Abstract: A microneedle includes a base having a support surface, and a projection that protrudes from the support surface, the projection having a through hole that penetrates the projection in an extending direction of the projection. The projection includes a flow path expansion section which is configured to expand a communication path that communicates between an inner space of the through hole and a space surrounding the projection in response to an increase in pressure of a fluid flowing in the through hole.

Abstract: A spring release mechanism for a drug delivery includes a fusible member to restrain a spring in a charged state. A heating element is utilized to selectively heat and sever the fusible member. When the fusible member is severed, the spring is allowed to discharge and drive the drug delivery device components operably coupled thereto.

Abstract: A trigger assembly for an automatic medication injection device. The trigger assembly includes an actuator that rotates when shifted axially, and at least one upstanding member extending from a biased drive element of the device toward said actuator which is rotated within the device housing when the actuator is shifted axially. The trigger assembly also includes a track and follower structured and arranged to guide the biased drive element when being rotated within said housing when the actuator shifts axially and to release the biased drive element for axial movement.

Abstract: An injecting gun for the treatment of animals with identification aid with a push button on the handle comprising a body formed by two main housings linked by their edges with delimitate the free space, in which there is an electronic card consisting of: a CPU (Central Processing Unit) which is connected by means of: a) a UART (Universal Asynchronous Receiver/Transmitter) module with connections to: i) a RFID (Radio-Frequency IDentification) module, ii) a wireless connectivity module; and iii) a keyboard; b) a GPIO (General Purpose Input/Output) module with connections to: iii) a plurality of LEDs (Light Emitting Diode), iv) a vibrator, vi) a buzzer, vii) a syringe sensor, viii) a verification sensor, and ix) a TFT (Thin-Film Transistor) liquid crystal parallel port; c) a USB module (Universal Serial Bus) with: x) a micro USB plug (micro USB); wherein, said CPU is connected to a memory; and wherein said CPU is connected to an energy source, which is connected to a charger and energy manager.

Abstract: A syringe needle shield that includes a first part and a second part. The first part is connected to the second part by a pivotable first connection portion. The second part is pivotable on the first connection portion toward the first part, and a needle hub is clamped between the first and second parts. The first and second parts are securely connected to each other by the first snapping portion which cannot be unlocked from each other. The first part is connected to a needle shield by a flexible plate. The shield receives a push force from its back so as to move from a first position to a second position. When the shield is located at the second position, a restriction portion is fixedly engaged with an engaging portion.
