Vacutainer blood collection system is a closed evacuated system, which consists of a sterile double-ended needle with safety valve, Kemico Vacutainer holder and sterile Kemico Vacutainer evacuated blood collection tubes with predetermined volume. Blood collected by threading the sleeve-covered end of the needle (NP) into the holder, then puncturing the patient’s vein with the other end (IV). After performing vein puncture, multiple tubes can then pushed into the holder one at a time, and the predetermined vacuum of the tube allows the required volume of blood to be collected, thus resulting in an optimal blood to additive ratio. Advantages to using Kemico Vacutainer 1.It prevents exposure by ensuring blood flows directly from the patient vein into the tube 2. There is a wide range of color-coded tubes available with additives for a variety of analytical tests covering laboratory disciplines such as hematology, clinical chemistry, immunology chemistry, coagulation, blood banking and others 3.There is no manual influence on the drawing of blood so the process remains consistent. The system is a more reliable alternative to the traditional needle and syringe technique 4.The tube cap closures color-coded according to the additive and the international standard (ISO 6710). 5.Kemico Vacutainer (plastic) blood collection tubes are made of clear latex free PET (Polyethylene Terephthalate), which is shatter resistant and offers a clinically tested safer alternative to glass
