A dual lumen IV administration set includes a first lumen having an inner diameter of a first value. A second lumen is paired with the first lumen, and the second lumen has an inner diameter of a second value that is greater than the first value. A flow merger merges flow output from a distal end of the first lumen and flow output from a distal end of the second lumen to form a single flow output in an exit lumen. An injection port intersects the first lumen, thereby providing injection access to flow therethrough, prior to merging with the flow output of the second lumen.

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen.

An automatic injection device includes an end sleeve and a syringe support mounted slidably with respect to the end sleeve. The syringe support is intended to carry an injection syringe provided with an injection needle and with a cap for protecting the injection needle. The automatic injection device includes a membrane formed by at least two locking elements which are mounted so as to slide substantially radially in the end sleeve between a configuration permitting passage of the cap for protecting the injection syringe, in which configuration limit stops of the at least two locking elements, intended to cooperate with a shoulder of the injection syringe, are moved away from each other, and a configuration permitting immobilization of the injection syringe, in which configuration the limit stops of the at least two locking elements are moved towards each other.

An illustrated view of an exemplary emergency kit for use in an emergency medical condition and a method for automating the ordering of the emergency kits for dentist is presented. The emergency kit is useful for providing short-term medical relief in an emergency while waiting for ambulance or other emergency medical personnel to arrive at the scene. The emergency kit provides a useful medical syringe for use by a dentist in a mouth of a patient experiencing an emergency medical condition.

An injector device includes a housing and a cartridge having a reservoir for medicament. The injector device further includes a needle unit comprising a needle, and an actuator. The needle unit is movably mounted to the housing and, prior to use of the injector device the reservoir, is sealed from the needle. The actuator is configured to move the needle unit 5 into engagement with the cartridge such that the needle is moved into fluid communication with the reservoir. A thread is arranged to cause rotation of the needle unit as the needle unit moves into engagement with the cartridge.

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.

Injection devices for delivering pharmaceutical compositions into the eye are described. Some devices include a resistance component for controllably deploying an injection needle through the eye wall. The resistance component may be disposed on the injector device, or on a portion of the injection device housing, or on a drug reservoir. Some devices may be removably attached to a drug reservoir, for example, through a luer connector. Other devices may comprise internal luer seal for securely connecting a drug conduit of the device to the luer cavity of a drug reservoir. Yet other devices may comprise a priming-enabling element to facilitate the drug priming of a shielded needle. Related methods and systems comprising the devices are also described.

A syringe barrel includes: a barrel body including a nozzle portion at a distal end thereof; and a cap removably mounted to the nozzle portion and configured to seal a distal end opening of the nozzle portion. The cap includes: an inner cap formed of an elastic material and configured to come in liquid tight contact with the nozzle portion in a mounted state in which the cap is mounted to the nozzle portion, and a cylindrical outer cap formed of a material having a higher hardness than the inner cap and fixed around the inner cap. The inner cap includes: a base portion, and a cylindrical wall extending from the base portion in a proximal direction and surrounding the nozzle portion.

The present invention provides a two-step auto-injection apparatus consisting of a housing, a protective sleeve cylinder, a pre-filled injection assembly and a drive feedback apparatus, wherein the pre-filled injection assembly is loaded into the housing, and the protective sleeve cylinder covers a needle of the pre-filled injection assembly, so that the protective sleeve cylinder directly contacts an injecting portion and the function of injection can be realized by pressing to trigger the drive feedback apparatus during use, thereby facilitating quick operation with a needle tip hidden in the whole process; the drive feedback apparatus of a piston in a needle cylinder is driven to combine a release mechanism with an ejection mechanism and a feedback mechanism, and the release mechanism is triggered by pressing the protective sleeve cylinder, so that the ejection mechanism is released, and the ejection mechanism interacts with the feedback mechanism in a form of collision, for example, to generate a sound signal and/or a haptic signal in the moment of release for prompting a patient to begin an injection; when the ejection mechanism finishes movement, the ejection mechanism interacts again with the feedback mechanism in the form of collision, for example, to generate the sound signal and/or the haptic signal for promoting the patient to finish the injection.

A hypodermic interface assembly is disclosed. The hypodermic interface assembly includes a hub; a cannula; a core member; and a cannula carrier. The core member is non-removably connected to the cannula. The cannula carrier is non-removably connected to the attachment member. The cannula carrier is controllably separable from the hub. A subassembly is also disclosed. The subassembly includes a hub; a cannula; and a core member. A proximal end surface of the core member is arranged at a predetermined hub-core distance away from a distal end surface of the hub.
