Abstract
The present invention is directed to a patient interface for use with an injector assembly, the patient interface having a removable cap, wherein removal of the cap after an injection disables the patient interface to prevent re-use.
Claims17
A patient interface for use in connection with a separate injector assembly, comprising:
- an injection stream enclosure having first and second ends and defining a cavity, wherein said first end defines an injection stream enclosure opening;
- a cap removably affixed to said first end of said injection stream enclosure, wherein said cap defines a cap opening, and wherein said cap is not integrally connected to the injector assembly;
- and
- wherein said injection stream enclosure opening and said cap opening are aligned to define an open pathway through the patient interface.
1 more element
An injector assembly comprising:
- an injection nozzle for expelling an injectate;
- a removable patient interface;
- and
- a retention lock movable between a first unlocked position and a second locked position;
- wherein said patient interface is held in place over said injection nozzle by said retention lock when said retention lock is in said second locked position.
2 more elements
A method for using a patient interface in connection with an injector assembly, comprising:
- inserting a patient interface comprising an injection stream enclosure and a removable cap over a nozzle of an injector assembly, wherein said inserting step moves an injection interlock from a first injection preventing configuration to a second injection permitting configuration;
- triggering said injector assembly to expel an injectate;
- ejecting said injection stream enclosure from said injector assembly thereby separating said injection stream enclosure from said cap;
- and
- ejecting said cap from said injector assembly after said step of ejecting said injection stream enclosure.
