New Microfluidic Blood-draw Device Could Replace Needle Sticks and Venipunctures at Medical Laboratories
By placing this low-cost, disposable device developed at the University of Wisconsin-Madison on their arms or abdomens, patients can collect their own blood at home in minutes
For more than two years, the nation’s media have been captivated by Theranos CEO Elizabeth Holmes’ vision of offering patients who need blood tests a finger stick collection instead of a venipuncture. Meanwhile, in research labs across the nation, there are credible efforts to develop ways to collect medical laboratory test specimens that require no needles at all.
On such effort may soon enter the market. It is an innovative, needleless blood-collection device called HemoLink developed by a research team at the University of Wisconsin-Madison. Users simply place a device with the diameter of a golf ball against their arms or abdomens for two minutes. During that time, the device draws blood from capillaries into a small container. Patients would then mail the tube of collected blood to a medical laboratory for analysis.
This non-threatening device is ideal for children. However, patients who require recurrent blood tests to monitor health conditions would also benefit, as it would save them frequent trips to clinical laboratories for blood draws using traditional needle-stick methods. (more…)
