摘要：
Provided is an Extraction Device for Collecting Blood Samples, including a Catheter and a Safety System “EDCBSCSS” wherein a catheter is inserted through a cannula, which retracts once the catheter is inside a vein, by means of a spring and safety latch mechanism, retaining the cannula within a housing. The retracted cannula remains immobile within the housing thus avoiding reutilization of the devise and accidental puncture wounds during its disposal. This EDCBSCSS has the advantages (a) among others of assuring that the cutting element has been disabled； (b) possessing a safety system for medical personal so that after the procedure no accidental puncture wounds occur and (c) being easy to handle. The EDCBSCSS is made up of three sequential operational systems, which are puncturing and retracting system which are located within housings and comprise a puncturing cannula； a catheter； a catheter space, a spring and a safety latch.
