A ventilator intelligent adjustment system and its application

Abstract

The invention discloses a ventilator air pressure adjustment and monitoring system and its application, which are used to adjust and monitor the ventilator air pressure. It includes an air supply unit, a control unit, an air guide unit and a patient circuit unit. The control unit includes a data acquisition module, Data processing module and data sending module, the air supply unit includes a speed regulation module for adjusting the speed of the fan, the air guide unit includes a sensing module, a secondary pressure regulating module, a temperature regulating module and a humidity regulating module, and the sensing module is used to detect the initial value And output values, including gas pressure, gas temperature, gas humidity and gas flow rate, the patient circuit unit includes a breathing detection module, which is used to detect the patient's breathing and other vital signs, and the data acquisition module is used to collect the sensing module and the breathing detection module The data processing module analyzes and processes the data of the data acquisition module, sends the processing results to the data sending module, and the data sending module sends the processing information to the air guide unit for air pressure adjustment.

Description

technical field [0001] The invention belongs to the technical field of ventilator support equipment, and in particular relates to a ventilator air pressure adjustment monitoring system. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. [0003] At present, ventilators on the market are mainly divided into 4 categories, namely: common single level (CPAP), fully automatic single level (APAP), fully automatic double level (VPAP AUTO), double level ST (BIPAP), according ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the existing technology only pays attention to the difference between the real-time output pressure of the ventilator and the target output pressure, so it is impossible to know exactly how to increase or decrease the speed flow of the fan to make the final real-time output of the ventilator The pressure is just around the standard output pressure, which brings the output pressure of the ventilator to rise and fall too slowly. Over-adjustment will cause the output pressure of the ventilator to oscillate or the difference between the output pressure and the target output pressure exceeds the allowable range of error. At the same time, through The data sending module feeds back the patient information to the doctor and family members in a timely manner, which is convenient for timely understanding of the patient's situation and the working status of the ventilator. When the patient is not breathing spontaneously, changing the oxygen content can stimulate the patient's lungs and make the patient Restoring breathing while improving breathing efficiency
