GROUND PROXIMITY RESEARCH UNIT OF BLOOD (FIRST NON-CONTACT BLOOD MONITOR STM_06196)
Researchers at Loughborough University (Loughborough University), central England, have developed a non-invasive method for monitoring the blood flow to the tissues of the body.
In the future, the new contactless technology can be used to monitor the activity of the heart, evaluate the overall condition of the patients during surgery and in the treatment of wounds and burns.
A team of researchers led by Professor Peter Smith (Peter Smith), the researcher Vincent Crabtree (Vincent Crabtree) and graduate student Ching Sharon (Sharon Cheang) has created a new device based on the use of optoelectronic technologies. Technology used today PPG (photoplethysmography) allows, thanks to a special detectors to monitor the condition of blood flow based on the degree of light absorption by cells of body tissues. #39;The use of this technology has always created problems in the study of difficult areas of the human body - said Peter Smith, a professor of photonic technologies and Head of Department of Electronic Technology at Loughborough University. #39;If the patient moves, it distorts the signal. Contactless system PPG even worsens the situation because the detector begins to react to extraneous light sources#39; - adds the professor.
It was therefore necessary to develop a means of adjusting signal.
Based on a series of experiments, the research team established a link between the movement and receive signals. The research results helped to create the appropriate light source, a detector system and computer programs that not only allow you to determine how traffic will affect the signal, but also automatically correct it.
The new technology will allow for more accurate studies in situations where contact with the skin is undesirable or impossible, such as burns and lesions of the peripheral arteries.
In addition, the new technology will help improve the diagnosis, early warning of diseases, the development of more accurate schemes of therapeutic treatment.
Research conducted by Professor Smith in 2000 as part of Gatsby Innovation Fellowship Scheme, became the basis of development of practical application of the new technology. Together with commercial partners, the company Stuert Medical Devices, the researchers will conduct trials of a unique system of remote monitoring in the clinic PPG Stirling Royal Infirmary, in Scotland, under the supervision of a specialist in the field of vascular surgery, Richard Holdsworth (Richard Holdsworth).
