Multi-sensor integrated wireless sputum deposition alarm system and method

Abstract

The invention discloses a multi-sensor integrated wireless sputum deposition alarm system and a multi-sensor integrated wireless sputum deposition alarm method. The system comprises a wireless sputum deposition alarm and a portable intelligent device, the wireless sputum deposition alarm comprises a sound sensor, a gas flow sensor and a gas pressure sensor, wherein the sound sensor, the gas flow sensor and the gas pressure sensor are used for collecting expiration characteristic information; the ADC data acquisition module is used for converting the electric signal containing the expiration characteristic information into a digital signal; the power management module supplies power to the wireless sputum deposition alarm; the central processing unit performs time sequence coordination and control on each module in the wireless sputum deposition alarm; the wireless information transmission module sends the digital signal to the portable intelligent equipment; the portable intelligent device carries out feature recognition on the digital signals, analyzes and outputs the sputum deposition degree and sends out corresponding alarm information. The sputum deposition degree in the mechanical ventilation process can be judged in real time, information collection is comprehensive, judgment is accurate, timeliness is high, the sputum deposition degree is displayed through intelligent equipment, and an alarm is given out in time.

Description

technical field [0001] The invention relates to the technical field of mechanical ventilation pipelines, in particular to a multi-sensor integrated wireless sputum accumulation alarm system and method. Background technique [0002] Sputum stasis is one of the main complications faced during mechanical ventilation. Sputum stasis will produce sputum scab, cause carbon dioxide retention, promote bacterial reproduction, cause lung infection, and affect respiratory mechanics parameters. Interfering with doctor's diagnosis will seriously threaten the safety of patients' lives . Therefore, it is very important to judge the degree of sputum deposition by external means in time. [0003] At this stage, lung sound recognition with a stethoscope is used to judge whether sputum is stagnant, but this method requires a lot of time and manpower, and there is no important basis for judging the degree of sputum stasis. Therefore, it is urgent to provide a wireless sputum accumulation alarm...

Problems solved by technology

[0003] At this stage, lung sound recognition with a stethoscope is used to judge whether sputum is stagnant, but this method requires a lot of time and manpower, and there is no important basis for judging the degree of sputum stasis

Therefore, it is urgent to provide a wireless sputum accumulation alarm system and method to monitor the accumulation of sputum in the user's mechanical ventilation circuit in real time in view of the difficulty in obtaining information on sputum accumulation and the difficulty in accurately and timely judging the degree of sputum accumulation. , in order to take timely measures to provide reference for users to eliminate phlegm, it has become an urgent technical problem that technical personnel in the nursing field need to solve in the process of mechanical ventilation for users at this stage
