This device uses infrared technology to help find veins
How? Well it works in a similar way to pulse oximetry. Haemoglobin in the blood absorbs infrared light. When AccuVein’s device is held above the skin, it can detect the difference in the haemoglobin concentration between the veins and surrounding tissue, projecting a map of the veins on the skin above them. Locating the point of needle placement is suddenly simplified for phlebotomy techniques.
This technique has been used for some time when drawing blood from newborns, but is now becoming more frequently used in adults. Those with particularly difficult venous access (DVA) can include:
- The elderly;
- Dark-skinned patients, whose veins may not be visible;
- Obese patients, whose veins may not be visible or palpable;
- Patients having many diagnostic or therapeutic intravenous procedures;
- Burn victims;
- Agitated or restless patients;
- Oncology patients on chemotherapy;
- Other patients with chronic diseases;
- Drug abusers.
