摘要

Set for venipuncture characterized by having a cannula with an anti-reflux system to prevent fluid outflow and a catheter with a safety device to prevent accidental punctures. The invention consists of a radio opaque cannula for channeling blood vessels or body cavities with a catheter that serves as a guide. The safety device, which prevents accidental punctures, consists of a hollow metal cylinder that protects the sharp bevelled end of the catheter when the cannula and catheter are uncoupled during the performance of the technique. It also incorporates an anti-reflux valve system housed inside, which prevents the outflow of body fluids to the outside during the maneuvers of connection to the cannula of the devices necessary for the administration of substances or the collection of samples of biological products. The set is protected by a sleeve until the moment of use. (Machine-translation by Google Translate, not legally binding)
