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 medicament delivery member housing assembly is disclosed that extends along an axis in a longitudinal direction from a proximal end to a distal end. The medicament delivery member housing assembly has a housing, a medicament delivery member, a proximal shield, and a distal shield. The housing can have a body and a flexible arm, the flexible arm extending in the longitudinal direction from a proximal end moveable relative to the body to a distal end attached to the body, wherein the flexible arm has a first surface facing towards the proximal end of the medicament delivery member housing assembly and a second surface facing in a radial direction relative to the axis. The proximal shield extends around a first end of the medicament delivery member, the proximal shield can have a surface facing towards the distal end of the medicament delivery member housing assembly to interact with the first surface of the housing during use.

There is provided a needle hub assembly for connecting to a barrel with plunger for assembling a syringe, comprising: a cylindrical depression in a proximal end portion of the needle hub assembly, the cylindrical depression having a flat bottom perpendicular to a longitudinal axis of the needle hub assembly, wherein the cylindrical depression is shaped for connecting to a nozzle of the barrel and for contacting between the flat bottom and a distal end of the nozzle surrounding an opening of the nozzle when the nozzle is disposed within the cylindrical depression, a lumen extending from the flat bottom of the cylindrical depression to a distal end portion of the needle hub assembly, and a cannula having a proximal cannula portion located within the lumen and a distal cannula portion extending distally from the distal end portion of the needle hub assembly.

A syringe adapter includes a housing having a first end and a second end positioned opposite the first end, with the housing defining a passageway, and a connector body having a first end and a second end positioned opposite the first end, with the connector body having a connection member configured to be secured to a mating connector. One of the housing and the connector body includes a tab and the other of the housing and the connector body defines a channel that receives the tab, with the connector body movable relative to the housing between a first position where the connector body is restricted from rotating relative to the housing in a first rotational direction and free to rotate relative to the housing in a second rotational direction, and a second position where the connector body is free to rotate in the first and second rotational directions.

A safety needle device for connection to a medical connector, including threaded connections. The safety needle comprises a collar configured to interdigitate with a conventional needle hub, the collar having attachment points for a hinged cap, the hinged cap being in a two-piece configuration. In further embodiments, the safety needle device comprises a removable hard needle cover configured to cover needle cannula and a distal portion of a needle hub. The hard needle enclosure further comprises a cap configured to interdigitate with the needle cover and cover a proximal portion of the needle hub. The cap and at least a portion of the needle cover are covered by a removable sleeve which holds the cap and the needle cover together. Even further embodiments comprise a needle hub, a needle cover, an adapter and a cap, the adapter configured to attach to a conventional needle cap.

A blood collection assembly includes a hub with a distal end, a proximal end, a hub outer surface and an internal opening extending therethrough. The assembly also includes a holder housing defining a receiving chamber and having a rearward end adapted to receive a sample collection tube within the chamber and a forward end including a receiving port extending into the chamber, where the receiving port receives a portion of the proximal end of the hub therein. An internal opening of the hub accommodates a puncturing element at the proximal end thereof for providing passage of a fluid therethrough, and the puncturing element contacts the sample collection tube. The hub and the holder housing include an interengaging structure extending substantially perimetrically therearound for axially locking the hub with the holder housing.

A swiveling intravenous therapy tubing connection system for easy rotational adjustment of an intravenous tubing line between a sterile container and a catheter used to administer a fluid to a patient features the sterile container which is a sterile intravenous fluid container and the catheter which is an intravenous therapy catheter located in the patient. The system features a length of intravenous therapy tubing having a female quick-connect swivel tubing connector located on a tubing first end and a quick-connect double swivel tubing connector located on a tubing second end. The female quick-connect swivel tubing connector is rotationally connected to a first mated male swivel tubing connector located on an intravenous fluid outlet of the intravenous fluid container. The quick-connect double swivel tubing connector is rotationally connected to a second mated male swivel tubing connector located on an intravenous fluid inlet of the catheter. The length of intravenous therapy tubing is designed to be infinitely rotatable in either direction.
