       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  is a schematic diagram of the operation of an intelligent system of ventilator and operating method thereof according to the present disclosure. 
     
    
    
     DETAILED DESCRIPTION 
     The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of them. 
     Referring to  FIG. 1 , an embodiment provided by the present disclosure: an intelligent system of ventilator and operating method thereof, including a ventilator and an input system, the ventilator including an alarm system, a monitoring system, a communication unit, and a ventilator control system; 
     Wherein, the ventilator is used to provide respiratory treatment to the patient. The ventilator mainly includes a gas source, an air-oxygen mixer, a humidifier and an external pipeline. The controller controls the operation of the air-oxygen mixer and the degree of steam supplied by the humidifier, which is transmitted to the breathing mask through the external pipeline to perform respiratory treatment on the patient; 
     The input system is used to input the patient&#39;s parameters and treatment requirements, and realize the record of the original data of the designed treatment plan. The parameters include the patient&#39;s weight, age, and the reason for respiratory treatment, an appropriate plan is thus calculated according to the patient&#39;s condition and which does not exceed the treatment range that the patient&#39;s body can withstand. The input system can be a computer, and the form of the input system is not limited, and it can be adjusted according to the actual case; 
     The ventilator control system is used to calculate the target data needed by the patient and design the treatment plan, wherein, the ventilator control system is connected with an external network. The ventilator control system can adjust the designed plan according to many respiratory treatment cases, and control the ventilator to realize the automatic operation of the ventilator. Compared with the traditional way that the medical staff constantly change the operating mode and adjust various parameters according to the operating conditions to achieve the established treatment goals, the present disclosure can alleviate the work pressure of the medical staff; 
     The communication unit is used for the data communication between the input system and the ventilator control system to realize the transfer of data from the input system to the ventilator control system. The communication unit may be a Bluetooth module, a wireless communication module, a 4G module, or a combination of two of them, or a combination of three, which can be adjusted according to the actual situation; 
     The monitoring system is used for real-time monitoring of the patient, returning the monitoring data to the processor. The processor compares the returned monitoring data with the preset target data in the memory. If a preset effect is not achieved, the ventilator will automatically prompt; 
     The alarm system is used to alarm in time according to the urgency of the patient and automatically enters an operating state of safety measures. There is no specific operating state for safety measures, but a preset respiratory treatment program is started, which is set up while the patient&#39;s parameters and treatment requirements are input into the input system. While there is no perfect treatment, this will minimize the harm to the patient. And wait for the medical staff to proceed with the next step, which will manually adjust the operating mode to adjust the respiratory treatment plan. 
     Further, the ventilator control system includes a processor, a controller and a memory; 
     wherein, the processor is used to receive the transmission data of the communication unit, handle the abnormal situation monitored by the monitoring system, store and call the data with the memory, and send the treatment plan to the controller to realize the safe automatic operation of the ventilator. In order to ensure the operating speed of the processor, the model of the processor is not regulated, but is adjusted in real time according to the actual scientific and technological development to lay a solid foundation for the patient&#39;s respiratory treatment; 
     The controller is used to receive the treatment plan of the processor, thereby realizing the control of the air-oxygen mixer and humidifier of the ventilator, and controlling the oxygen supply to adjust the oxygen concentration and the oxygen humidity according to the treatment plan; 
     The memory is used to store the target data of the patient calculated by the processor and to design the treatment plan. The memory includes main storage and backup storage to avoid medical accidents caused by abnormal data loss. 
     An operating method of an intelligent system of ventilator, which includes the following steps: 
     At step 1: the operator inputs the patient&#39;s parameters and treatment requirements to the ventilator through the input system, and at the same time presets the mode of the operation state of safety measure to ensure that the operation state of safety measure will causes minimal damage to the patient, and the communication unit serves as an intermediate communication component to send data to the processor; 
     At step 2: the processor calculates the target data needed by the patient and designs the treatment plan according to the patient&#39;s parameters and treatment requirements, and stores the data and plan into the memory for easy recall and to ensure that the data is not lost. Through the control of the controller, the ventilator operates automatically according to the designed plan; 
     At step 3: when the ventilator is operating according to the set mode parameters and time, the monitoring system continuously monitors the patient in real time and sends the monitoring data back to the processor; 
     At step 4: the processor compares the returned monitoring data with the preset target data in the memory. If a preset effect is not achieved, the ventilator will automatically prompt; 
     At step 5: when the patient has an emergency and reaches a set warning value, the ventilator will give an alarm through the alarm system and automatically enter an operating state of safety measures, and to inform the medical staff whether to change the design plan in the next step. At this time, the medical staff can choose to operate the ventilator normally according to the original situation or continue operation after changing the plan (which is manually modified) according to the situation. 
     Furthermore, when the ventilator is operating according to the set mode parameters and time, a new treatment plan can be set according to the actual operating conditions and stored in the memory. In the correction of human-computer interaction, while achieving the target effect, the working time of medical staff is greatly reduced and work efficiency is thus improved.
