"Needle retraction device, processes for using the same, and to use a safety device of needle, medical device and medical extensu00ecvel retractable needle.Process for using the same, devices of needle catheter extensu00ecvel and retractable, and security of extension and retraction of the needle for mechanized phlebotomy.The medical needle used in a device for extension and retraction of the needle mechanized medical process for transporting, preparing and retract safely.At the end of a medical procedure, a medical needle retractable phlebotomy, set of needle and catheter extensu00ecvel retractile, and process to use a device of self retractable needle ".Process and apparatus associated with retraction safe of medical needles (140, 140, 140, 2070, 2320) after use.Are disclosed configurations for systems of self retractable needles for both, the withdrawal of blood (10, 610, 820, 2010, 2400), the syringe (510, 900, 1010) and systems for insertion of the catheter (400, 800,2300).The manufacture of the invention requires only a minimum amount and complexity of parts such that a cost of manufacture designed is potentially low enough to allow theGadget is competitive in cost with systems of needle retractable contemporaries. Also disclosed are processes to manufacture and assemble each of the configurations are disclosed.A configuration for withdrawal of blood (2400) may be made with as few as three molded pieces.The mechanisms of energy storage and needle retraction comprise elastic pipe (180, 570, 1180) and parts of piston vacuum generator (416, 2351).In a configuration of the elastic pipe (10, 510, 610, 800, 820, 900, 1010, 2010, 2400), constructive control, selective volumes of pipe stretched (180, 570, 1180) inhibits effectively.Regurgitamento flow from the needle (140, 140, 540, 1140, 2070, 2320).In all settings (10, 510, 610, 400, 800, 820, 900, 1010, 2010, 2300 and 2400), the retraction of the needle operation is manipulated with one hand.Which allows the other hand of technical to be used in the care of the wound.A combination of parts comprising a housing of the device (20, 30, 50, 500, 520, 620, 630, 752, 802, 842, 902, 904, 1020, 2020, 2200, 2302, 2402), and a cover of the needle (120, 120, 268524, 720, 720, 804, 1190, 2350), are used as a transport container which protects a medical needle (140, 140, 540, 1140, 2070.2320) from inadvertent contamination without requiring special packaging, reducing, with it, even more, the costs of the apparatus.
