Vein Contast Enhancer:
Uses a near-infrared camera to capture a real-time video image of the patient’s veins, a PC to enhance the contrast of the image and a desktop video projector to display it on the skin in real time. An array of near-infrared LEDs surrounding the camera’s lens illuminates the skin at a wavelength of 740 nanometres. This wavelength is strongly absorbed by blood, but is scattered by the surrounding tissue. The image from the camera is fed to a PC running imaging software that maps the image onto a bright green background in real time and boosts the contrast between the veins and surrounding tissue. The PC then feeds this image to a projector that beams it onto the skin.



Finding the source of virus in bacteria while taking care of someone with a primary immune deficiency becomes a common task.

This is a great product from Discovery Channel Store. I've been trying to join their affiliate program with no luck..
If they approve me I will put a direct link to the product..

A futuristic device that painlessly injects medications through microscopic pores in the skin.

The hand-held, ultrasonic device applies sound waves to the skin for 15 seconds, disrupting a protective membrane to allow fluids to flow in or out. The openings allow larger molecules, including those of many drugs, to pass through quickly. After 24 hours, the skin returns to normal.

The SonoPrep device consists of a battery operated power and control unit, a hand piece containing the ultrasonic horn and the disposable coupling medium cartridge, and a return electrode. (see picture above) A clinician performs a skin permeation treatment by applying the ultrasonic hand piece to the patient’s skin. The clinician pushes the hand piece down on the patient’s skin to activate the ultrasonic horn. The patient holds the return electrode so that the device automatically shuts itself off, based on a drop in skin impedance (as measured by current moving through the return electrode) once the proper level of skin permeation is achieved.
