GAS SAMPLING DEVICE AND METHOD Russian patent published in 2018 - IPC A61B5/97 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically a gas sampling device, a gas sampling unit and a gas analysis method. Device includes an inlet for receiving gas. Device comprises a vacuum pump fluidly connected to the inlet for drawing the gas through the inlet. Device includes a flow sensor for measuring the flow of gas drawn through the inlet. Flow sensor is located upstream of the pump. Pump and the flow sensor are located downstream of the inlet. Device comprises a flow controller for controlling the pump in dependence of the measured flow of the gas. Flow controller is able to control the pump to draw a predetermined mass or volume of gas through the inlet. Gas sampling unit comprises a gas sampling device and a gas collector fluidly connected to the gas sampling device. Gas analysis method includes providing a gas sampling device. Gas collector is then connected to the gas sampling device. Further, the inlet of the gas collector or inlet of the gas sampling device is connected with a source containing the gas to be analysed. Gas sampling devices are then activated to draw gas through the gas collector in such a way as to draw a predetermined mass or volume of gas.

EFFECT: more reliable and accurate comparison of samples and the possibility of a uniform analysis of multiple samples.
