摘要： A method of making a needle guard includes providing a mold having a portion defining a volume, the volume being a hollow cylinder with non-uniform walls with a pair of slots therein, the slots being open at one end and closed at the other end, the pair of slots having a major portion of constant width. The walls are thicker at the other end than at the one end. The method includes filling the volume with polymer and releasing a molded part from said mold and cooling a molded part resulting from the filling and releasing such that temperature that the widths of the pair of slots is non-uniform after cooling. The needle guard has upper and lower jaws defining a channel and coming together at a hinge. A winged needle can be inserted between the jaws, with the wings of the winged needle passing through slots between the jaws.

摘要： A needle set includes a needle guard with upper and lower jaws each defining a channel and joined at a hinge. Each edge of the jaws is aligned with and spaced from a respective edge of the opposite jaw defining slots alongside walls of the jaws. A winged needle has a cannula, a hub with a pair of wings with a tube connected to the cannula by the hub. The hinge portion has an opening into which the tube is received, and the side walls are spaced apart to permit the hub to be received between the jaws with the wings in the slots. The slots progressively narrow to a first spacing that is narrower than a thickness of each wing at a point thereof, and thereafter expand linearly to a second spacing that is substantially equal to the thickness of the wings.
