Blood draws typically require trained professionals to perform and can be both frightening and painful to patients. Tasso, Inc., a spinoff of the Unviersity of Wisconsin-Madison, has developed a device that can be applied by the patients themselves to nearly painlessly draw blood.
The device works thanks to capillary action, slowly pulling in blood through a tiny channel over a two minute period. Once the process is complete, the patient simply takes the device to a clinical lab for testing. Since current methods require refrigeration of blood samples during shipment, DARPA is giving Tasso $3 million to work with other firms to develop a way to extend to a week the time the blood samples can be safely stored at up to 140° F (60° C).
This will allow for all kinds of blood testing away from clinical facilities, as well as easy and convenient way for patients to monitor their conditions without regularly schlepping to the hospital.
