<p>Separable integral donor connector (15) with an improved clamping mechanism for use with flexible blood collection tubing (16). The device is positioned in line with the blood tubing (16) between a phlebotomy needle and the collection bag (10). Separation of the device is accomplished by manipulation and breaking of a thin frangible ring area (26) and drawing the sections (18 and 24) of the device apart. This separation exposes an internally-mounted needle (36) that may be used for penetration of sample collection tube closures and subsequent collection of blood samples. The present embodiment of this invention includes improved manually-operated clamping means that are flexibly biased away from the blood tubing. Clamping jaws (28 and 30) of differing lengths are disclosed which, when engaged, overlap and cause an area of tubing to be collapsed into a distinctive, S-shaped configuration which crimps and more effectively seals the tubing against blood flow. The clamping device is free from restraints permitting simple, one-handed operation, as well as the broadest control over the blood flow. </p> |
