Medical valve and method of use
First Claim
1. A medical valve comprising:
- a housing defining an internal cavity and having a proximal end and a distal end, the housing having an opening at said proximal end adapted to receive a male Luer, said housing further including at its distal end a skirt with screw threads on an internal surface thereof and a tube, the cavity including a rigid element for facilitating fluid transfer therethrough, the cavity having a neck portion adjacent the opening and a main portion adjacent the neck portion, the main portion having a larger cross-sectional diameter than the neck portion;
a seal element comprising an external wall, the seal element positioned in the cavity and movable from a first position to a second position, the seal element having a proximal end, a neck portion, and a distal end, the proximal end of the seal element being substantially flush with the proximal end of the housing in the first position to facilitate antiseptic wiping at a proximal end of the connector, the proximal end of the seal element in the second position being moved in a distal direction from its location in the first position, the distance between the proximal end of the seal element and the distal end of the seal element being less in the second position than in the first position, the seal element in the first position having at least one indentation located in its exterior wall in the neck portion of the cavity and at least one indentation located in its exterior wall in the main portion of the cavity, the at least two indentations configured to facilitate movement of the seal element.

Abstract
A closed system, needleless valve device includes a generally tubular body defining an internal cavity. On the proximal end of the body there is an opening which is preferably sufficiently large to receive an ANSI standard tip of a medical implement. The distal end of the body has a generally tubular skirt. The valve also includes a hollow spike having a closed tip. The spike includes at least one longitudinal 18-gauge hole located distal the tip, and is seated inside the cavity such that the tip is below the proximal end of the body. An annular support cuff is connected to the spike which seals off a portion of the cavity of the body such that an upper cavity containing the tip is defined. The valve also includes a plastic, resilient silicone seal which fills the upper cavity and opening and covers the tip of the spike so as to present a flush surface. An adaptor enables the valve to be attached to a resealable container.

17. A medical valve comprising:
-
a housing defining an internal cavity and having a proximal end and a distal end, the housing having an opening at said proximal end adapted to receive a male Luer, said housing further including at its distal end a skirt with screw threads on an internal surface thereof and a tube, the cavity having a neck portion adjacent the opening and a main portion adjacent the neck portion, the main portion having a larger cross-sectional diameter than the neck portion, wherein a spike is positioned inside the cavity and configured to act as a fluid conduit through at least a portion of the housing member; a seal element comprising an external wall, the seal element positioned in the cavity and movable from a first position to a second position, the seal element having a proximal end, a neck portion, and a distal end, the proximal end of the seal element being substantially flush with the proximal end of the housing in the first position to facilitate antiseptic wiping at a proximal end of the connector, the proximal end of the seal element in the second position being moved in a distal direction from its location in the first position, the distance between the proximal end of the seal element and the distal end of the seal element being less in the second position than in the first position, the seal element in the first position having at least one indentation located in its exterior wall in the neck portion of the cavity and at least one indentation located in its exterior wall in the main portion of the cavity, the at least two indentations configured to facilitate movement of the seal element. - View Dependent Claims (18, 19, 20, 21, 22, 23, 25, 26, 27, 28, 29, 30, 31, 32)
