Abstract: The present invention provides a device for drawing blood from a patient, and methods of drawing blood from a patient using the device. The device comprises holders for collection vials and holders for a luer assembly, and does not require mechanical movement of any part of the device. The device is easy to fabricate, simple to use, and long-lasting.

Abstract: A device for use with conventional blood receptacle assemblies provides increased safety and stability for blood collecting operations. The blood drawing device includes a holding element for securing a blood collecting assembly and a clamping mechanism for clamping a blood sampling tube. A sliding mechanism is provided for sliding the blood sampling tube into engagement with the blood collecting assembly. In an alternative embodiment, the blood drawing device may be configured to include a carriage assembly moveably attached to a base and holding a plurality of blood tubes for blood collection. A servo motor moves the carriage assembly relative to the base. A mechanism reciprocates the blood tube between a first and second position such that movement of the tube causes the tube to engage a needle inside the blood collecting assembly.
