DEVICE FOR CARDIORESPEPRATORY ANALYSIS AND METHOD FOR ESTIMATION OF CARDIORESPIRATORY STATE Russian patent published in 2017 - IPC A61B5/205 A61B5/245 A61B5/1455 G08B19/00 

FIELD: medicine.

SUBSTANCE: device for cardiorespiratory analysis contains a body with a control unit fixed thereto and an infrared pulse oximetric sensor for measuring the pulse rate and blood oxygenation. The body is made in the form of a telescopic cane equipped with a handle. The cane bends are reinforced with plastic clutches in the joints to prevent any folding. At the end of the cane, there is a wheel block in the form of a pair of wheels and a wheel speed sensor interacting with them. The wheels of the wheel unit are mounted on the common axle. The wheel speed sensor is a digital tachometer, which includes a reed switch and magnet attached to the wheel unit. The control unit is fixed on one of the cane bends and equipped with a liquid crystal display, an on/off switch and a reset button. An infrared pulse oximetric sensor is mounted on the cane handle. The microcontroller is capable of analyzing the measured readings, generating a warning message on the display screen and issuing a signal to turn off the sensors. A method for cardiorespiratory state estimation includes a test used for cardiorespiratory analysis. At that, the device is held by the handle. The thumb is placed on the infrared pulse oximetric sensor. A test program is selected, the name of which appears on the LCD. Steps are performed. Data on the distance travelled and pulse oximetry are transmitted by connecting the microcontroller via a USB cable to an external PC, where they are visualized in the form of graphs and stored in a database.

EFFECT: increase accuracy of measurements during study and assessment of the dynamics of changes in the parameters of the cardiovascular and respiratory systems when performing a sample with a functional load.
