Abstract

Abstract A protecting sheath for an IV infusion set of the type including a length of tube with a hollow needle at one end, and a pair of outwardly projecting flexible wings adjacent the end of the tubing with the needle is disposed on the tube and adapted to be slid over the needle to cover the needle. The sheath includes a hollow generally tubular body having a forward end oriented toward the needle and a rearward end oriented away from the needle. The body has at least three longitudinally extending fingers separated by slots extending from the forward end of the body toward the rearward end. Each of the slots is dimensioned to receive only one of the wings to allow at least part of sheath to be slid past the wings to cover the needle after use.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 170 words
In an improved IV infusion set of the type including a length of tube with a hollow needle at one end, and a pair of outwardly projecting flexible wings adjacent the end of the tubing with the needle and a sheath slidably disposed on the tube and adapted to be slid over the needle to cover the needle after use, the improvement comprising: said sheath comprising a hollow generally tubular body having a forward end oriented toward the needle and a rearward end oriented away from the needle, said body having means for more readily accommodating said wings other than 180 degrees apart when said tube is pulled through said sheath to secure said wings, said means comprising at least three longitudinally extending fingers separated by slots extending from the forward end of the body toward the rearward end, each of the slots being dimensioned to receive only one of the wings to allow at least part of said sheath to be slid past the wings to cover the needle.
Claim 2
Dependent Claim 170 words
In an improved IV infusion set of the type including a length of tube with a hollow needle at one end, and a pair of outwardly projecting flexible wings adjacent the end of the tubing with the needle and a sheath slidably disposed on the tube and adapted to be slid over the needle to cover the needle after use, the improvement comprising: said sheath comprising a hollow generally tubular body having a forward end oriented toward the needle and a rearward end oriented away from the needle, said body having means for more readily accommodating said wings other than 180 degrees apart when said tube is pulled through said sheath to secure said wings, said means comprising at least three longitudinally extending fingers separated by slots extending from the forward end of the body toward the rearward end, each of the slots being dimensioned to receive only one of the wings to allow at least part of said sheath to be slid past the wings to cover the needle.
Claim 3
Dependent Claim 28 words
