Abstract:
1. A magnetically sealed intravenous access valve, comprising: a housing having an upper portion and a lower portion, the lower portion defining an open interior region and having a pair of longitudinally opposed apertures formed therethrough, the upper portion having an open upper end in communication with the lower portion; a pair of hollow tubes, each of the tubes having longitudinally opposed first and second ends, the first ends being slidably disposed within the pair of longitudinally opposed apertures formed through the lower portion of the housing, the tubes being adapted for connecting the valve inline in a patient's vein, the lower portion of the housing and the tubes forming a continuous passage for the flow of blood; a valve plate mounted in the upper portion of the housing, the valve plate having an eccentric aperture formed therethrough; an obturator rotatable within the upper portion of the housing and positioned against an upper surface of the valve plate, the obturator having an upper and lower end and an obturator channel formed axially therein, the obturator channel terminating in an eccentric spout formed in the lower end of the obturator so that selective rotation of the obturator aligns the eccentric spout with the eccentric aperture formed through the valve plate to form a continuous passage from the obturator channel into the lower portion of the housing, the valve plate and the obturator being retained in abutting relation by magnetic attraction; a retainer having an upper portion and a hollow lower portion, the lower portion being disposed in the open upper end of the upper portion of the housing, the obturator being rotatably disposed within the lower portion of the retainer to secure the obturator within the upper portion of the housing, the upper portion of the retainer extending upwardly from the upper portion of the housing and having a retainer channel formed therethrough, the retainer channel being aligned with and communicating with the obturator channel; and a hollow key having opposed open upper and lower ends, the hollow key being removably received within the retainer and obturator channels so that the lower end of the hollow key releasably engages the obturator; wherein selective rotation of the hollow key aligns the eccentric spout formed in the lower end of the obturator with the eccentric aperture formed through the valve plate, the hollow key being adapted for transfer of fluid between the key and the lower portion of the housing.
