Systems and method for a dynamic seal assembly for a fluid delivery system

Abstract:

Methods and systems are provided for a sealing system for a dynamic nuclear polarization (DNP) system. In one embodiment, a system comprises: a reservoir including an inlet opening; an outer tube; and a tapered seal shaped to seal against the inlet opening and the outer tube, the tapered seal including: a first section removably coupleable to a second section; a through-hole formed by a first plurality of inner surfaces of both the first section and the second section, the through-hole shaped to encircle the outer tube; and a vacuum channel extending through, from an outer surface to an inner surface of the first plurality of inner surfaces, one of the first section and second section. In this way, the tapered seal may be coupled around the fluid passage without inserting a tip of the fluid passage through the through-hole of the tapered seal, thereby maintaining a sterility of the system.
