Abstract
A needleless valve system includes a cannula comprising a cannula tip; a valve comprising a valve tip, wherein the valve is disposed around the cannula; and a housing comprising a housing tip, wherein the cannula tip, the valve tip, and the housing tip comprise a flat surface when the needleless valve system is in a sealed position.
Claims20
A compressible cannula valve comprising:
- a cannula comprising a cannula tip, a central lumen, and a radially extending opening in fluid communication with the central lumen;
- a resiliently compressible valve comprising a valve tip, wherein the valve is disposed around the cannula and a protrusion of the valve is received radially within the radially oriented opening;
- and
- a housing comprising an inner cavity, wherein cannula and valve are positioned in the inner cavity;
- wherein when the valve changes from a sealed position to an open position, the valve deforms and withdraws the protrusion of the valve out of the opening.

A compressible cannula valve comprising:
- a housing having a housing wall around a cavity and a housing opening;
- a cannula having a base, a cannula tip extending within the cavity from the base toward the housing opening, and a lumen extending from the base to a radially oriented opening on a side of the cannula below the cannula tip;
- and
- a resiliently compressible valve surrounding the cannula and having a valve tip, a shoulder, and a protrusion, the shoulder extending radially toward the housing wall and, when in a sealed position, the protrusion extending radially into the radially oriented opening;
- wherein, in the sealed position, the valve tip is proximal to the cannula tip and the shoulder and the protrusion are axially aligned with the radially oriented opening.
