VF1 is such useful device for nurses and doctors, which is designed to help health care practitioners find veins quickly and clearly.
This facilitates rapid access to veins in emergency situations, when every second can count, and patients may be experiencing health problems which can make veins difficult to find.
VF1 can also be used to facilitate routine blood draws and other medical procedures, increasing patient comfort and procedure efficiency.
These device can work in several different ways. The creative VF1 consists of a device with a very bright source of illumination which is held against the skin to literally light up the veins, as they will show up in bright contrast to the surrounding tissue. In addition to custom devices designed to use light to find veins,doctors and nurses have also long used flashlights in much the same way, usually for a fraction of the cost.
