HemoLink is a disposable, needleless blood-collection device developed by a research team at the University of Wisconsin-Madison. A medical startup company called Tasso Inc. in Madison, Wisconsin has been formed to commercialize this device.
HemoLink is a golf ball sized device that is placed against an arm or the abdomen for 2 minutes. Microfluidics create a slight vacuum that pulls blood from capillaries through tiny channels in the skin and into a small tube. The device collects 150 uL of blood.
Tasso plans to market the device to patients who regularly need to have blood drawn to monitor chronic disease or treatment. Patients will be able to draw their own blood sample and send it to a clinical laboratory.
