Respiratory mechanical parameter detection device and method suitable for monitoring of chronic obstructive pulmonary disease

Abstract

The invention relates to a respiratory mechanical parameter detection device and method suitable for monitoring of the chronic obstructive pulmonary disease. The device comprises a signal collection module capable of monitoring gas flow and pressure, a micro-processing unit, a Bluetooth communication module, a mobile terminal device and a software analysis module. The collection module achieves continuous monitoring for the pressure and flow of an air duct, a collected continuous signal is preprocessed through the micro-processing unit and then sent to the mobile terminal through the Bluetoothcommunication module, and the software analysis module on a mobile terminal estimates a respiratory mechanical parameter through a constrained optimization method and on basis of a segment-type forced respiration model. According to the respiratory mechanical parameter detection device suitable for monitoring of the chronic obstructive pulmonary disease, the air duct resistance coefficient and adaptability of the inspiration phase and expiration phase of a patient with the chronic obstructive pulmonary disease can be detected in real time, the device helps to monitor the respiratory therapy condition of the patient with the chronic obstructive pulmonary disease, and accordingly reference and help are provided when a doctor adjusts the treatment scheme.

Description

technical field [0001] The invention belongs to the field of equipment detection and signal processing methods, and in particular relates to a device and method for detecting respiratory mechanical parameters suitable for COPD monitoring, which are used to detect respiratory mechanical parameters of patients with limited expiratory breath, and are effective for chronic obstructive pulmonary disease Guardianship is helpful. Background technique [0002] Chronic obstructive pulmonary disease (COPD for short) is characterized by incompletely reversible airflow limitation, which affects the patient's normal breathing and even endangers life. Respiratory mechanical parameters are indicators that can directly reflect the performance of the patient's respiratory system. For example, patients with COPD usually have an increased airway resistance coefficient. Effective monitoring of respiratory mechanical parameters is of great significance for the monitoring of COPD. At present, th...

Problems solved by technology

The blocking method must block the ventilation and cannot achieve real-time monitoring. The method of parameter estimation based on the respiratory mechanics model is more suitable for patients without spontaneous breathing. Once the patient has spontaneous breathing, invasive measurement of esophageal pressure instead of pleural cavity pressure is required to complete the estimation. , invasive and not real-time
