Christie Medical Holdings is a Memphis-based company developed a system called Christie VeinView which uses infrared light to look under your skin for veins. It’s being trialed in US hospitals now.
The device detects veins and then projects the image of them in real-time on top of the arm to help the medical worker know where to put the needle. It provides an accurate image of the patient’s blood pattern to see patterns up to 0.6 inches and veins up to 0.4 inches deep.
A fine detail mode also increases the contrast in the image, bringing out more detailed vein formations. This can allow a clinician to find turns in a person’s veins, called bifurcations, and valves. The user can also take up to 200 static images of patient vasculature – the arrangement of blood vessels in the body.
Here’s how it operates:
- The device attaches to a movable arm that can be wheeled into position, to keep it steady while observing a patient’s arm.
- It works by emitting near-infrared light, which is absorbed by hemoglobin in the blood and then reflected by surrounding tissue.
- The information is processed digitally by the unit, and projected in real-time onto the skin.
- This provides an accurate image of the patient’s blood pattern.
Christie’s president, George Pinho said “It is the only device of its kind that has been shown through clinical studies to increase both first-stick success and patient satisfaction by up to 100 per cent while reducing medically unnecessary [catheter] lines by over 30 percent.”
Let’s hope it comes to a hospital in my neighborhood soon!
