Hightech Vampirella/Weird Wide Web

Een goede ader vinden om een vaatje bloed af te tappen is soms nog verdraaide...

lastig. Om blauwe plekken, misprikken en trauma's te voorkomen kunnen zowel Vampirella's als doktoren gebruik maken van Veinviewer: vernuftige technologie om het bloedvatenstelsel onder de huid zichtbaar te maken. Voor de hardcore Techdiva's de werking:

The VeinViewer is a mobile biomedical device consisting of the following four technologies.

1. Infrared light source - The light source emits a harmless, near-infrared light reflected back to the surface from the tissue surrounding the vein, while no light is reflected back from the blood inside the vessel.
2. Digital video camera - The digital video camera captures the near-infrared light reflected back from the patient.
3. Image processing unit - The microprocessor adds contrast and projects this image back on the skin in their actual location.
4. Digital image projector - The projector displays these real-time images of the vasculature onto the surface of the skin.

The VeinViewer utilizes a near-infrared light source to differentiate red blood cells from surrounding tissues. These infrared light photons are received by a detector located in the video camera; a computer digitizes these photons, produces an image and projects the onto the patient's skin to show the location of the veins.
