Development of a Venous Collapse Prevention Device for Blood Draw

Abstract Blood sampling typically involves puncturing a superficial vein with needle and then creating vacuum (e. g., syringe) to transfer the blood from venous system collection container. In some cases, walls collapse due excessive generated. this work, device is presented that prevents can be combined any available on market. The mechanism of preventing based tubular segment interconnected between syringe, which collapses at lower pressure than vein. prototype was tested evaluated using test rig simulates draw. experiments proved functionality phantom.
