Respiration-supporting cooperative control method and comprehensive integrated system

Abstract

The invention discloses a respiration-supporting cooperative control method. The method comprises the following steps that 1, a control system starts a respirator module; 2, physiological parameters of the human body and respiration information of the respirator module are monitored; 3, a monitoring module sends the monitored physiological parameters of the human body and the respiration information of the respirator module to the control system, and whether to start an oxygen generation module or not is confirmed; 4, when the physiological parameters of the human body are smaller than a preset threshold value, the oxygen generation module is started by the control system, oxygen is supplied to the respirator module to achieve mixing of air and oxygen, and then the mixture of air and oxygen is delivered to a patient side. The cooperative control method can monitor the physiological parameters and the respiration information of the respirator module, the control system works cooperatively with the oxygen generation module, the function of the oxygen generation module is guaranteed, the function of the oxygen generation module is also guaranteed, the running modes of the oxygen generation module can also be controlled, the using range is expanded, and the treatment quality is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a collaborative control method and comprehensive integration system for respiratory support. Background technique [0002] There are a large number of patients with chronic respiratory diseases (COPD, asthma, neuromuscular disease, pulmonary fibrosis, silicosis, and respiratory failure caused by various reasons) in China, which have become serious public health problems that endanger public health, and the prevention and control situation is very severe. Especially for COPD, the epidemiological survey data from 2012 to 2014 showed that the prevalence of COPD among people aged 40 and over in my country was 13.7%. Statistics from the World Health Organization show that the death rate of COPD in my country ranks first among all countries, second only to the sum of cardiovascular and cerebrovascular diseases and the sum of cancer, and becomes the third leading cause of deat...

AI Technical Summary

Problems solved by technology

The advantage is that the oxygen concentration of the mixed gas is stable, the gas flows through the sensor (pressure sensor and flow rate sensor, etc.) with little interference, accurate measurement, accurate breathing triggering, switching, and stable respiratory mechanical parameters such as tidal volume measurement; the disadvantages are: 1. Oxygen consumption is large, especially for high oxygen concentration mechanical ventilation. 2. This type of ventilator is expensive, generally at 200,000-400,000 / unit

The advantage is that it saves oxygen, but the disadvantage is that extra gas is added during the mechanical ventilation process. The ventilator control system cannot accurately judge the user's breathing trigger and switch, and the calculation of respiratory mechanics parameters is inaccurate. The gap between ventilator therapy and family and community ventilator therapy

Therefore, the treatment time of patients in the ICU is prolonged, and the risk of nosocomial infection in the ICU is increased, which is not conducive to the timely application of ventilator sequential treatment for patients in the stable period at home or in the community.

[0005] Secondly, it is generally more economical to use an oxygen generator to supply oxygen to families or communities. The oxygen flow range is generally 3-10 liters / minute. , short use time, inconvenient ventilation)

In addition, the blood oxygen saturation value of the patient during mechanical ventilation will fluctuate with the condition of the patient, whether oxygen access is needed or not. Theoretically, the oxygen generator can be started and stopped on demand to reduce power consumption (the power consumption of the oxygen generator is 400 -600 watts), in fact, manual operation is extremely cumbersome and hardly feasible
