Abstract
Disclosed herein are various embodiments of a multi-chamber syringe module for use in fine needle aspiration or other procedures. The multi-chamber syringe module includes a multi-chamber cartridge. The multi-chamber cartridge can include a plurality of fluid chambers. The multi-chamber syringe module also includes a needle manifold that is rotatably coupled to the multi-chamber cartridge. The multi-chamber syringe module further includes a luer fitting hub fixedly coupled to the needle manifold at a first end and selectively coupled to a biopsy needle at a second end.
Claims9
A multi-chamber syringe module for use with a biopsy needle, the multi-chamber syringe module comprising:
- a multi-chamber cartridge having a plurality of fluid chambers and a support that houses the plurality of fluid chambers, each of the plurality of fluid chambers being selectively and temporarily manually deformable to create one of a fluid vacuum therein or a fluid evacuation therefrom, said plurality of fluid chambers forming an exterior wall of the multi-chamber cartridge visible to a user;
- a luer fitting hub having a first luer fitting hub end and a second luer fitting hub end, the first luer fitting hub end configured to receive the biopsy needle;
- and
- a needle manifold having a first needle manifold end and a second needle manifold end, the first needle manifold end being fixedly coupled with the second luer fitting hub end, and the second needle manifold end being rotatably coupled through a fluid channel to the multi-chamber cartridge to selectively fluidly couple the biopsy needle received in the first luer fitting hub end with one of the plurality of fluid chambers based on a relative rotational arrangement of the needle manifold and the multi-chamber cartridge,
- said fluid channel including a passage to selectively connect the biopsy needle located on a centerline of the multi-chamber syringe module with the plurality of fluid chambers that are axially offset from the centerline, and
- wherein said each of the plurality of fluid chambers is configured to enforce a particular order of events.
