The present disclosure provides medical devices, particularly medical grade needles with removable tips, as well as methods of needle tip installation and removal, and devices therefor. Needle tip installation and removal devices may include needle tip installation and removal tools and kits, including hand held and manipulated tools that facilitate the installation and removal of needle tips, particularly on vascular access port needles. Such installation and removal devices may provide more expedient hook up of the access port for the therapy. Also, the installation and removal of the needle tips may be conducted in a more sterile manner.

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 pre-filled medical delivery assembly assembled and configured to allow delivery of a single dose of a therapeutic agent (e.g., vaccine, drug, medicament, etc.) from a Blow-Fill-Seal (BFS) vial to a patient. The delivery assembly generally includes a modular design consisting of separately constructed components cooperatively arranged and coupled to one another. In accordance with some embodiments, the medical delivery assembly comprises a hub connector that includes at least one alignment track on an interior portion thereof, configured to receive a corresponding wing of a BFS vial which it is designed to couple with.

A pen needle includes a hub supporting a needle and a distal needle shield that can retract to expose the needle and return to an extended position to cover the needle. A proximal needle shield moves to an extended position to cover a proximal end of the needle. A spring extends between the distal and proximal needle shields to bias the distal and proximal needle shields to their respective extended positions. A locking member on the distal needle shield cooperates with the hub to lock the proximal and distal needle shields in their respective extended positions. An indicator in the hub couples to the distal needle shield when the distal needle shield is moved to a retracted position. The indicator moves with the distal needle shield to the extended position of the distal needle shield where the indicator indicates that the pen needle is no longer usable.

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.

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.

One embodiment is directed to a system for injecting, comprising a syringe body defining an interior medicine chamber; a stopper member configured to be inserted into the interior medicine chamber to contain medicine within the medicine chamber; a plunger member configured to be manually manipulated to insert the stopper member relative to the syringe body; and a needle having proximal and distal ends, the proximal end comprising an anchoring geometry configured to be at least partially inserted into the stopper member such that upon retraction of the stopper member, the needle is pulled proximally along with the stopper to be at least partially contained within the interior medicine chamber.

The present disclosure provides a tubular needle cover of a pen needle assembly, the tubular needle cover comprising: a distal sleeve extending along a longitudinal axis between a proximal end and a distal end, wherein the distal sleeve comprises a first fastener; a proximal cover comprising a proximal wall extending in a direction transverse to the longitudinal axis, wherein the proximal cover comprises a second fastener, and wherein the first fastener is attached to the second fastener; and a proximal opening arranged in the proximal wall of the proximal cover, wherein the proximal opening and the distal sleeve are coaxial; and wherein the distal sleeve and the proximal cover are two separate components.

A pen needle (10) includes a hub (34) supporting a needle (28) and a distal needle shield (14) that can retract to expose the needle during injection and return to the extended position after use and locked in the extended position cover the needle. A proximal needle shield (16) moves to an extended position with respect to the hub (34) to cover a proximal end (34) of the needle. A spring (64) extends between the distal needle shield (14) and the proximal needle shield (16) to bias each needle shield to the respective extended position. A locking member (78) on the distal needle shield cooperates with the hub to lock the needle shields in the extended position. An indicator (94) in the hub engages and couples to the distal needle shield (14) when moved to the retracted position. The indicator (94) moves with the distal needle shield (14) to the extended position where the indicator is visible through the distal needle shield (14) indicating that the pen needle is no longer usable.
