Heading out to the doctor's office to get your blood drawn can be a real pain, especially for patients with long-term illnesses that require frequent blood tests. The developers behind this new vampire-like invention are trying to make life a little bit easier for those folks by allowing them to take their own blood samples.
The new gadget is called HemoLink. It's a disposable device the size of a pingpong ball that uses suction to pull a blood sample out of a small prick in your skin. In just two minutes, you'll have a usable sample.
The gadget then transfers the sample to a vial that you can send to your doctor or a lab.
