Bi-level performance evaluation method of respiratory support equipment and respiratory support equipment

Abstract

The invention relates to a bilevel performance evaluation method of a respiratory support device and the respiratory support device. The dual-level performance evaluation method for respiratory support equipment, including steps: S1, data collection: setting the active simulated lung under a single pathological model, setting n groups of different dual-level detection conditions to control the operation of the respiratory support equipment, the detection and evaluation of the active simulated lung For the required detection data, under each group of detection conditions, the eigenvalues ​​of the detection data within the detection time are taken to form a single group of detection data vectors, and a total of n groups of detection data vectors are obtained; and the n groups of detection data vectors are sent to the controller Middle; S2, data processing; S3, performance evaluation. The method obtains multiple sets of detection data vectors by collecting respiratory support equipment under the condition of running multiple sets of detection conditions, and obtains projection vectors after normalization processing and projection tracking processing, and then according to multiple sets of detection data vectors respectively and the projection vector to obtain the comprehensive evaluation score.

Description

technical field [0001] The invention relates to the field of performance detection of respiratory support equipment, in particular to a bilevel performance evaluation method of respiratory support equipment and the respiratory support equipment. Background technique [0002] In the use of non-invasive respiratory support equipment, bi-level usually only provides high pressure when inhaling, and lowers the pressure when exhaling, usually including S, S / T, T, PC and other working modes. In general clinical applications, the S / T mode is the most common, and the present invention also mainly performs performance evaluation on this mode. [0003] The patent document with the patent number ZL 201610740141.6 discloses medical respiratory support equipment and its method for continuously measuring airway resistance and compliance. It uses high-frequency oscillating pressure and airflow to measure respiratory resistance and lung compliance, and monitors patients in real time during v...

[0003] The patent document with the patent number ZL 201610740141.6 discloses medical respiratory support equipment and its method for continuously measuring airway resistance and compliance. It uses high-frequency oscillating pressure and airflow to measure respiratory resistance and lung compliance, and monitors patients in real time during ventilation. Airway resistance, the main problem to be solved is also to solve the situation that the normal data of the respiratory support equipment cannot be monitored in time, resulting in poor user experience

Moreover, at present, there are many brands of respiratory support equipment circulating in the market, but there has been no objective and fair evaluation method that can truly reflect the bi-level performance of non-invasive respiratory support equipment, allowing people to truly understand the differences between different respiratory support equipment. Where is the performance difference between
