Medical salt mist concentration detection device and calculation method

Abstract

The invention provides a medical salt mist concentration detection device and a calculation method. The medical salt mist concentration detection device comprises a capacitor array sensor, a data collection control system and an image reconstruction upper computer, the capacitor array sensor is arranged on a medical salt mist delivery pipe and used for converting change of salt mist concentration into change of output capacitance of the sensor, the data collection control system is connected with the image reconstruction upper computer and used for controlling the capacitor array sensor to detect capacitance of medical salt mist, converting the capacitance into digital quantity and transmitting the digital quantity into the image reconstruction upper computer, and the image reconstruction upper computer reconstructs a salt mist concentration distribution image in the delivery pipe through a capacitance tomography image reconstruction algorithm and calculates salt mist concentration through a salt mist concentration detection calculation method. The medical salt mist concentration detection device has the advantages of high accuracy, high sensitivity, high resistance to stray capacitance, high safety and high instantaneity.

Description

technical field [0001] The invention belongs to the technical field of medical detection devices, and relates to a medical salt spray concentration detection device and a calculation method. Background technique [0002] Medical nebulizer is a kind of equipment used in the treatment of various upper respiratory diseases and belongs to medical equipment. Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The medical nebulizer is used to atomize the liquid medicine or powder into tiny particles, and the medicine enters the respiratory tract and lungs for deposition through inhalation, so as to achieve The purpose of painless, rapid and effective treatment. [0003] The delivery of the atomizer is mostly a gas-solid two-phase flow system. Since it is difficult to explain the complexity and randomness of the gas-solid two-phase flow system from a theoretical point of view, and the theoretical research is ins...
