Respirator intelligent adjusting system and application thereof

Abstract

The invention discloses a respirator air pressure adjusting and monitoring system and application thereof. The respirator air pressure adjusting and monitoring system is used for adjusting and monitoring respirator air pressure, and involves an air supply unit, a control unit, an air guide unit and a patient loop unit; the control unit comprises a data acquisition module, a data processing moduleand a data sending module; the air supply unit comprises a speed adjusting module used for adjusting the rotating speed of a draught fan; the air guide unit comprises a sensing module, a secondary pressure adjusting module, a temperature adjusting module and a humidity adjusting module, wherein the sensing module is used for detecting initial values and output values of air pressure, air temperature, air humidity, air flow rate and the like; and the patient loop unit comprises a respiration detection module, wherein the respiration detection module is used for detecting respiration conditionsand other vital signs of patients; and the data acquisition module is used for acquiring information of the sensing module and the respiration detection module, the data processing module is used foranalyzing and processing data of the data acquisition module and sending a processing result 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
