Abstract
Systems and devices for interfacing between a medicinal vial, a hypodermic needle, and an injection device such as a syringe, comprising a valve, functionally associated with said vial adaptor, said injection device port, and said needle, said valve having a first orientation wherein said injection device port is in fluid flow communication with said vial adaptor and a second orientation wherein said injection device port is in fluid flow communication with said hypodermic needle, wherein rotation of said injection device port between a first position and a second position thereof, drives transition of said valve from said first orientation to said second orientation.
Core Innovation
The disclosure describes an injection system that includes a housing, a vial adaptor for connection to a vial, a syringe connector rotatable between a first medicament filling orientation and a second injection orientation, and a hypodermic needle. A valve removably held within the housing is functionally associated with the vial adaptor, the syringe connector, and the hypodermic needle.
In the first medicament filling orientation of the valve, the syringe connector is in fluid flow communication with the vial adaptor, and the longitudinal axis of the vial adaptor coincides with a longitudinal axis of the syringe connector. Rotation of the syringe connector between the first and second orientations drives transition of the valve from the first medicament filling orientation to the second injection orientation.
In the second injection orientation, the syringe connector is in fluid flow communication with the hypodermic needle, thereby switching fluid flow communication from the vial adaptor to the hypodermic needle. Additional embodiments include longitudinal displacement and disconnection of the vial adaptor relative to the valve in the injection position, a locking arrangement that prevents transition back to the filling orientation, housing architectures and compartments for housing a sterile and/or tamper-proof needle enclosure, and valve position markers and vial-adaptor position markers providing user feedback via visual, audible, and/or tactile indications.
Claims Coverage
The document includes one independent claim, supported by multiple dependent claims. The inventive features focus on a rotatable syringe connector that drives a valve between two orientations to switch fluid flow communication from a vial adaptor to a hypodermic needle, with specified axial alignment in the filling orientation.
Valve switching by rotatable syringe connector
A valve removably held within a housing is functionally associated with a vial adaptor, a syringe connector, and a hypodermic needle, where the valve has a first medicament filling orientation in which the syringe connector is in fluid flow communication with the vial adaptor and a second injection orientation in which the syringe connector is in fluid flow communication with the hypodermic needle, and rotation of the syringe connector between the first orientation and the second orientation drives transition of the valve from the first medicament filling orientation to the second injection orientation.
Axial alignment in medicament filling orientation
In the first medicament filling orientation of the valve, a longitudinal axis of the vial adaptor coincides with a longitudinal axis of the syringe connector.
First-to-second fluid flow communication switching
The syringe connector is in fluid flow communication with the vial adaptor in the first medicament filling orientation and is in fluid flow communication with the hypodermic needle in the second injection orientation.
Overall, the claim coverage emphasizes the structural and functional coupling of a rotatable syringe connector with a valve having two orientations, where the rotation drives valve transition and switches fluid flow communication from the vial adaptor to the hypodermic needle, with axial alignment of the vial adaptor and syringe connector in the medicament filling orientation.
