It is often difficult for doctors to get a needle of a syringe into the patient's vein. The greatest problems arise with children, with people suffering from cardiovascular diseases and obesity, as well as with victims of heat strokes, according to the Internet edition for girls and women aged 14 to 35 Pannochka. Net According to an online edition of the Washington Profile, the Georgia Institute of Technology has developed a simple and inexpensive device designed to search for veins in a person who needs an intravenous injection.

The principle of operation of the new device is based on the well-known "Doppler effect" - the characteristics of electromagnetic or sound waves, change when interacting with moving objects (the phenomenon was first described by the Austrian physicist Christian Doppler in 1842). The "Doppler effect", for example, underlies the action of the radar.

To search for veins, ultrasonic waves are used. The physician moves the device by hand, with the shape and size of a fountain pen, over the arm or leg of the patient. "Pen" is able to distinguish veins from arteries. When a vein is detected, an audible signal is given and an injection.
