摘要：
The utility model relates to the field of medical technology, namely to devices for functional diagnostics of the human cardiovascular system using the principles of photoplethysmography (PPG). A device for a comprehensive assessment of the state of the arterial bed includes a housing made with the possibility of placing the terminal phalanx of the finger in it, and two red and infrared light sources (1, 2) placed in the housing, which are capable of irradiating the phalanx of the finger and connected to a current source ( 12), controlled by a microprocessor (11) for alternating connection, a silicon photodetector (3), installed with the possibility of receiving a finger of light reflected or transmitted through the phalanx tissue and connected to the input the microprocessor ode (11) through a series-connected current-voltage converter (6), a voltage amplifier (7), a low-pass filter (8), a sampling and storage circuit (9) and an analog-to-digital converter (10), a silicone heating element (4 ) with a temperature sensor (13) connected to the microprocessor (11), while the silicone heating element (4) is connected to a voltage source (18) controlled by the microprocessor (11) and is located at the contact site of the skin of the terminal phalanx of the finger with light sources (1, 2) and photodetector (3), pneumatic A chamber (5) with a pressure sensor (17) connected to the microprocessor (11), through a valve (16) connected to the microprocessor (15) controlled by the microprocessor (11), the microprocessor (11), and outputs / outputs connected to the memory device (20) ), and outputs - with wired and wireless interfaces (21, 22), and inputs - with a barometer (19) and a pressure sensor (14) mounted on the body with the possibility of contact with the phalange of the finger. Provides reliability, simplicity, reliability and reduced time for examination with a comprehensive assessment of the state of the arterial bed.Полезная модель относится к области медицинской т
