Medical adapter having needleless valve and sharpened cannula
First Claim
1. A medical adapter for interconnecting a pierceable site with a male fluid connector, comprising:
- a body having a first end and a second end;
a sealed needleless site located at the first end of the body, having a fluid flow port for receiving the male fluid connector;
a sharpened cannula located at the second end of the body, the cannula having a sharpened tip;
an internal fluid channel interconnecting the fluid flow port of the needleless site with the sharpened cannula so that fluid may flow between the two;
a first clip arm mounted to the body, the first clip arm extending to the tip of the sharpened cannula and having a distal end;
a claw at the distal end of the first clip arm facing in the direction of the sharpened cannula, the arm and the claw protecting the sharpened tip; and
a handle mounted to the first clip arm such that applying sufficient force to the handle will cause the claw of the first clip arm to move away from the sharpened cannula tip.

Abstract
A medical adapter having both a needleless valve and a sharpened cannula is used to connect or adapt pierceable septa containers or other devices having different sizes to needleless connection. The adapter includes a needleless site at one end and a sharpened cannula at the other end protected by spring arms. These arms include claws at their distal ends to grasp the neck of the pierceable septum device to which the sharpened cannula is to be inserted. The claws include sharpened points for gripping the device. The arms are located on either side of the adapter body and are connected to the body through springs. Handles are also included on the arms for use by the operator to separate the arms against the spring forces during engagement of the adapter with the septum. In one case, the handles include finger grips located above the springs for pressing the handles inward to open the arms and claws and in another case, the handles are located closer to the distal ends of the arms for pulling the arms outward. The adapter in one case comprises only three parts for reduced materials and manufacturing expense.

6. A medical adapter for interconnecting a pierceable site with a male fluid connector, comprising:
-
a body having a first end and a second end; a female connection site located at the first end of the body, having a fluidflow port; a sharpened cannula located at the second end of the body, the cannula having a sharpened tip; an internal fluid channel interconnecting the fluid flow port of the female connection site with the sharpened cannula so that fluid may flow between the two; a first shroud mounted to the body, and surrounding the sharpened cannula except at the sharpened tip; and a second shroud mounted to the body, and surrounding the sharpened cannula, the second shroud having a length at least as great as the sharpened cannula. - View Dependent Claims (7, 8, 9, 10, 11)

12. A medical adapter for interconnecting a pierceable site with a male fluid connector, comprising:
-
a body having a first end and a second end and a sealing portion at the second end having a size selected to fit within tubing at a pieceable site and create a fluid-tight seal with the tubing; a needleless site located at the first end of the body, having a fluid flow port and comprising a resiliently deformable piston received within the body, the piston having a bore, the piston shiftable between a first position at the first end of the body and a second position, wherein positioning of the piston in the first position causes the piston to be deformed so as to occlude the bore and positioning of the piston in the second position allows the piston to assume its undeformed state in which the bore is unoccluded; a sharpened cannula located at the second end of the body, the cannula having a sharpened tip; wherein when the piston is in the second position, it provides a fluid path between the first end and the sharpened cannula; a first clip arm mounted to the body, the first clip arm extending to the tip of the sharpened cannula and having a distal end; a claw at the distal end of the first clip arm facing in the direction of the sharpened cannula and protecting the sharpened tip;
wherein the claw comprises a sharpened point facing the sharpened cannula;a handle mounted to the first clip arm such that applying force to the handle will cause the claw of the first clip to move away from the sharpened cannula tip; and a spring connected to the first clip arm to urge the distal end of the first clip arm toward the sharpened tip of the cannula, wherein the spring comprises a resilient connecting link between the first clip arm and the body. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A medical adapter for interconnecting a pierceable site with a male fluid connector, comprising:
-
a body having a first end and a second end; a needleless site located at the first end of the body, having a fluid flow port and comprising a resiliently deformable piston received within the body, the piston having a bore, the piston shiftable between a first position at the first end of the body and a second position, wherein positioning of the piston in the first position causes the piston to be deformed so as to occlude the bore and positioning of the piston in the second position allows the piston to assume its undeformed state in which the bore is unoccluded; a sharpened cannula located at the second end of the body, the cannula having a sharpened tip; wherein when the piston is in the second position, it provides a fluid path between the first end and the sharpened cannula; a first clip arm mounted to the body, the first clip arm extending to the tip of the sharpened cannula and having a distal end; and a claw at the distal end of the first clip arm facing in the direction of the sharpened cannula and protecting the sharpened tip. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
