A syringe holder includes: a barrel body that holds a syringe; a holder opening; deformation promoting portions; and radial movement-restricting portions. The radial movement-restricting portions are provided close to the deformation promoting portions. Being brought into contact with first portions, the radial movement-restricting portions restrict the syringe from moving in a radial direction with respect to the barrel body.

An assembly nest for transporting a tubular sub assembly of a drug delivery device on an automated production line, in which the tubular sub assembly includes a tubular body and a cap that is wider than the tubular body. The assembly nest includes a base against which a sub assembly of a drug delivery device is mountable to orientate said sub assembly in a predetermined position; and locking mechanism having a resilient member to urge the locking mechanism into one of: an unlocked position, in which a sub assembly of a drug delivery device can be mounted to the base; or a locked position, in which the locking mechanism engages a mounted sub assembly to retain it in its predetermined position on the base.

An apparatus includes a housing coupled to a medicament container, which is coupled to a needle. An injection assembly is disposed within the housing and includes an energy storage member and an actuation rod. A distal end portion of the actuation rod is disposed within the medicament container. The energy storage member can produce a force on a proximal end portion of the actuation rod sufficient to move the distal end portion of the actuation rod within the medicament container. This can convey at least a portion of a substance from the medicament container via the needle when a distal tip of the needle is disposed within a first region of a target location. The force is insufficient to move the distal end portion of the actuation rod within the medicament container when the distal tip of the needle is disposed within a second region of the target location.

A syringe includes a syringe body, a syringe cone having a distal opening, and a connection arranged in the region of the syringe cone, wherein the syringe body includes a first material and the connection includes a second material, and wherein the first material is different from the second material and the second material is a softer material than the first material.

A valved needle assembly including a needle hub provided to a proximal end side of a hollow needle, and a valve member incorporated therein for blocking communication with the hollow needle. A protrusion protrudes from a distal end side toward a proximal end side inside the needle hub and the valve member blocks the proximal end side of the protrusion inside the needle hub. A central valve part of the valve member having a slit moves toward the protrusion such that the slit is opened and placed in communication by the protrusion. The central valve part includes a distal end tubular part and a proximal end tubular part extending from its outer circumferential portion toward the distal end side and the proximal end side respectively.

The invention relates to a safety assembly having—an attachment ring attached to the tip of the container and—a safety device covering at least the distal end of the needle, the safety device attached to the attachment ring. The attachment ring has an inner ring having an inner face provided with a snap feature, which engages a complementary snap feature on the tip of the container to prevent axial movement of the inner ring with respect to the container. The snap feature moves radially to engage the complementary snap feature on the tip of the container; and an outer ring is fixed on the inner ring, with a sleeve portion surrounding at least a portion of the inner ring to prevent radial movement of the snap feature once the snap feature has engaged the complementary snap feature on the tip of the container.

A drug injection device contains a needle holder, an ejector, a needle member, and an actuation assembly. The needle holder defines a drug delivery direction extending toward the injection end. The ejector contains a fixing segment that is fixed to the needle holder and located in the drug delivery direction, and the abutting segment extending toward the injection end and protruding beyond the needle holder. The needle member is movably arranged relative to the needle holder and contains a needle shaft connected to a needle hub coaxially arranged with the ejector for the abutting segment inserting into the needle shaft. The actuator assembly connects the needle holder and the needle shaft for driving the needle member between a first position and a second position with respect to the needle holder.

A smart drug injection device is disclosed, comprising a main body, a circuit board, a display, a syringe and a transmission mechanism; the main body comprises an accommodating space and a power button; the circuit board comprises a control unit and a storage unit; the transmission mechanism comprises a motor, a screw rod, a propelling block and a movable clamp, with the control unit electrically connected to the storage unit, the power button, the motor and the display, the motor connected to the screw rod, the propelling block movably arranged on the screw rod, the movable clamp disposed at one end of the propelling block and movable between two positions; the syringe is on one side of the main body and comprises a cylinder and a needle holder, one end of the cylinder has a needle and the other end is assembled with the needle holder.

A syringe set, a syringe and a set include a first syringe having a first connection port and a drug container having a second connection port. The first connection port includes an injection needle attachment structure to which an injection needle is attachable, and a blocking member that is disposed in the injection needle attachment structure and blocks attachment of the injection needle. When the second connection port is connected to the first connection port, the blocking member is connected to the second connection port side, and when the second connection port is detached, the blocking member is detached from the first connection port so as to allow the injection needle to be attached to the first connection port.

Medical device assemblies having a connection mechanism for securely connecting a hub to fluid storage containers in a luer slip relationship are described. An exemplary medical device includes a hub forming a cavity, a second indicating element disposed within the cavity that engages the hub. Additional features of the medical device include a second indicating element contoured to form a line contact with the hub. In a specific configuration, the hub includes a first indicating element attached to the hub and extending proximally into the cavity having a protrusion. In a more specific configuration, the medical device includes a fluid storage container that has an indication system for visually indicating optimal fluid-tight engagement of the hub and the fluid storage container.
