Abstract

An intravenous catheter and cannula assembly as a sterile package with a flexible catheter partially telescoped within the cannula which is of the break-away needle type having wings to be manipulated in parting the cannula from the vein-inserted catheter; and a plastic handle interfitted with the wings for manipulation thereof and serving to secure a plastic bag or sheath thereto as a sterile covering for the remaining length of the catheter therein; and with a protective tube-like cover for the needle end of the cannula to maintain the sterile condition of the assembly as a whole prior to vein insertion use.

Claims

1. A sterile catheter and cannula assembly, comprising a breakaway split cannula needle with a catheter tube telescoped therein and a removable protective tube covering the needle end of the cannula and having radially projecting wings to be separated in removing the cannula from the implanted catheter tube, a flexible plastic sheath enclosing at least the wings and included catheter tube, and a handle member with handle sections interfitted with and enclosing the cannula wings with the included sheath portion sandwiched therebetween for attachment, the free edges of the handle sections being provided with slots receiving the free edges of the cannula wings for interlocking engagement therewith, whereby separation of the handle sections will spread the cannula wings and needle with rupture of the sheath for removing the cannula from the implanted catheter tube.

2. An assembly as claimed in claim 1, wherein the free edges of the handle sections are directed outwardly for finger gripping thereof.

3. An assembly as claimed in claim 2, wherein the handle sections are provided along the edges thereof with mutually interfitting lug and recess means.

4. An assembly as claimed in claim 1, wherein the handle sections are provided along the edges with mutually inter-fitting lug and recess means with the cannula wings disposed therebetween.
