Abstract
A medical valve transitions between an open mode that permits fluid flow, and a closed mode that prevents fluid flow. To that end, the valve has a housing with an inlet and an outlet, a post member moveably mounted within the housing and a distal seal member. The post member moves distally within the housing to fluidly connect the inlet and outlet upon insertion of a medical implement into the inlet. The post member also moves proximally within the housing to fluidly disconnect the inlet and outlet upon withdrawal of the medical implement. The distal seal member has a tapered wall region that surrounds a normally closed aperture. The distal movement of the post member opens the aperture and inverts the tapered wall region.
Claims60
A medical valve having an open mode that permits fluid flow, and a closed mode that prevents fluid flow, the medical valve comprising:
- a housing having an inlet and an outlet;
- a post member moveably mounted within the housing, the post member being distally movable within the housing to fluidly connect the inlet and outlet after insertion of a medical implement into the inlet, the post member being proximally movable within the housing to fluidly disconnect the inlet and outlet upon withdrawal of the medical implement;
- and
- a distal seal member having a tapered wall region about a normally closed aperture, distal movement of the post member inverting the tapered wall region to open the aperture.
A medical valve having an open mode that permits fluid flow, and a closed mode that prevents fluid flow, the medical valve comprising:
- a housing having an inlet and an outlet;
- a post member moveably mounted within the housing, the post member being distally movable within the housing to fluidly connect the inlet and outlet after insertion of a medical implement into the inlet, the post member being proximally movable within the housing to fluidly disconnect the inlet and outlet upon withdrawal of the medical implement;
- and
- a resilient member with a distal seal member having a normally concave proximal surface portion with an aperture therethrough, the resilient member supporting the post member within the housing, insertion of the medical implement inverting the normally concave portion from a concave shape to a convex shape to open the aperture.
A medical valve having an open mode that permits fluid flow, and a closed mode that prevents fluid flow, the medical valve comprising:
- a housing having an inlet and an outlet;
- a post member moveably mounted within the housing, the post member being distally moveable within the housing to fluidly connect the inlet and outlet after insertion of a medical implement into the inlet, the post member being proximally moveable within the housing to fluidly disconnect the inlet and outlet upon withdrawal of the medical implement;
- and
- a resilient member having a distal seal member with a normally closed aperture and a plurality of compression fingers, the compression fingers applying a radially compressive force on the aperture when in the closed mode, distal movement of the post member opening the aperture to transition the valve from the close mode to the open mode.
A method comprising
- connecting a medical valve to a patient, the medical valve comprising a housing having an inlet and an outlet, a post member moveably mounted within the housing, and a distal seal member having a tapered wall region about a normally closed aperture;
- inserting a medical implement through the inlet;
- moving the medical implement distally within the housing to transition the valve from an open mode to a closed mode, distal movement of the medical implement moving the post member distally to invert the tapered wall region, open the aperture, and fluidly connect the inlet and outlet;
- and
- transferring fluid between the medical implement and the patient through the valve.
