摘要：
summary blood sampling extraction device including a catheter and a safety system edcbscss blood sampling extraction device including a catheter and a safety system in which a flexible catheter is provided instead of a metal cannula with pointed ends for blood extraction. This catheter is inserted through a traditional cannula, which retracts when the catheter is inside the vein by means of a spring and locking mechanism, retaining the cannula within a rigid sheath. The retracted cannula remains immovable within the rigid sheath to prevent reuse of the device and injury by accidental puncture during disposal. This edcbscss has the advantages of (a) reducing or eliminating the use of a sharp-tipped metal cannula that remains in the vein for the duration of the complete procedure； (b) use a plastic cannula or catheter for blood sample extraction, which provides the patient with greater comfort and assurance that the cutting element has been eliminated； (c) have a safety system for medical personnel so that after the procedure no additional puncture occurs； and (b) be easily manipulated. edcbscss is composed of three sequential operating systems, which are the puncture and retraction system located within the shelters (4) and (5), composed of: (1) a puncture cannula； (2) a catheter； (3) a catheter space； (9) a spring and (8) a safety lock.resumo dispositivo de extração para coleta de amostras de sangue, que inclui um cateter e um sistema de segurança edcbscss dispositivo de extração para coleta de amostras de sangue, que inclui um cateter e um sistema de segurança, no qual é apresentado um cateter flexível em vez de uma cânula metálica com extremidades pontiagudas para extração de sangue. este cateter é inserido através de uma cânula tradicional, que se retrai quando o cateter estiver no interior da veia, por meio de uma mola e mecanismo de trava de segurança, retendo a cânula dentro de um abrigo rígido. a cânula retraída permanece imóvel dentro do abrigo rígido, de fo
