  • Development of the device for detecting the blooded vessels

    An experimental device designed for the detection of peripheral veins during the injection and infusion was developed on the basis of recording the difference in the intensity of the optical signal reflected from the vessels and surrounding tissues. The device allows to perform the detection of the locations of vessels, to determine their projection, to confidently distinguish veins and arteries. The effectiveness of the application is shown in tests on healthy people and patients with diabetic angiopathy. The device is very compact, has a simple design and low cost.

  • Approbation of experimental devices for visualization of blood vessels

    In the article results of approbation of the experimental devices designed for visualization of blood vessels developed by the authors are presented. Experimental device number one is an emitter of infrared light, the experimental device number two is a emitter of visible red light. Devices can be recommended for use in patients with no factors impeding vascular imaging and in patients with elevated body mass index.
