In the embodiment of the application, the ventilation device is in communication connection with the respiratory signal detection device, the respiratory signal detection device is an external detection device, namely the respiratory signal detection device and the ventilation device are two independent devices and do not share a processor; the respiratory signal detection device is responsible for acquiring respiratory data of a patient and sending the acquired respiratory data of the patient to the ventilator. The respiration signal detection device body can be a wearable contact sensor of a wrist strap or a chest strap, and can also be a non-contact sensor, so that a wearer is more comfortable when the respiration data of a patient is measured.
The mode of data communication between the ventilation device and the external detection device can be wireless or wired, but the data transmission must be safe and reliable. The ventilator may specifically be an open gas circuit ventilator.
In this step, the first patient breathing data is data related to the breathing of the patient, which is collected by the breathing signal detection device and sent to the ventilator, and may be calculated data or raw data, and the first patient data includes, but is not limited to, the fluctuation signal generated in the chest of the patient during inspiration and expiration.
Because the ventilator establishes a communication connection with the respiratory signal detection device, the respiratory signal detection device can transmit the data to the ventilator when acquiring the respiratory data of the patient, and the ventilator can receive the respiratory data of the patient transmitted by the respiratory signal detection device.
And 102, controlling the output gas flow according to the first patient respiratory data.
In this step, according to the actual breathing situation of the patient that the first patient respiratory data that the above-mentioned respiratory signal check out test set of external formula sent reflected promptly, the gas flow size of control output to make open gas circuit ventilation equipment can match with patient's demand for the gas flow that the patient carried, both avoided breathing hurriedly, when the ventilation demand is strong at the patient, the condition that the gas flow of ventilating is the undersize and can't effectively assist the patient to breathe, avoided again that the patient breathes smoothly, when the ventilation demand is weaker, the gas waste's problem is caused to the gas flow of ventilating too big.
The embodiment of the invention has the following advantages:

Because breathing signal check out test set and ventilator are two independent equipment, this breathing check out test set that also is external check out test set, it can accurately acquire patient's breathing data to breathe data transmission for ventilator with the patient, then ventilator can carry out flow control to output gas accurately according to this patient's breathing data promptly, and then the realization is according to the accurate ventilation of patient's actual breathing situation.
Optionally, in an embodiment, the first patient respiratory data is encrypted data, and the step 102 includes steps 201 to 202.
In this embodiment, in order to ensure data security, after detecting and obtaining actual respiratory data of a patient, the respiratory signal detection device encrypts the actual respiratory data according to a preset encryption protocol to obtain the first patient respiratory data, and then sends the first patient respiratory data to the ventilation device according to a preset communication protocol through the pre-established communication connection with the ventilation device.
Step 201, decrypting the first patient respiratory data according to a preset encryption protocol to obtain decrypted second patient respiratory data.
The first patient respiratory data is obtained by encrypting the actual respiratory data of the patient through the preset encryption protocol, so that the first patient respiratory data can be decrypted according to the preset encryption protocol to obtain second patient respiratory data, and under the condition of error-free data transmission, the second patient respiratory data is the same as the bookmarked respiratory data of the patient.
And step 202, controlling the output gas flow according to the second patient respiratory data.
In this step, because the decrypted second patient respiratory data reflects the actual respiratory condition of the patient, the output gas flow is controlled according to the second patient respiratory data, so that the gas flow delivered to the patient by the open gas circuit ventilation equipment can be matched with the patient demand, and accurate ventilation according to the respiratory demand of the patient is realized.

Optionally, in a specific embodiment, the second patient respiratory data includes a patient chest fluctuation signal, and the step 202 includes steps 2021 to 2022.
Step 2021, obtaining a respiratory signal and a respiratory frequency of the patient according to the chest fluctuation signal.
In this step, the breathing signal includes an inspiratory phase and an expiratory phase of the patient; the step is to analyze the inspiratory phase, the expiratory phase and the respiratory frequency of the patient according to the chest fluctuation signal. The inspiration time phase and the expiration time phase correspond to inspiration and expiration respectively, continuous inspiration and expiration are one-time respiration, the respiration frequency is the respiration frequency generated in the preset time, and the preset time can be 1 minute.
Step 2022, controlling the output gas flow according to the respiration signal and the respiration frequency.
In the step, the ventilation gas flow is controlled in real time according to the received breathing time phase and breathing frequency of the patient, so that the ventilation gas flow is saved on the premise of meeting the ventilation requirement of the patient.
Optionally, in another specific embodiment, the first patient respiratory data is obtained by encrypting, by a respiratory signal detection device, a respiratory signal and a respiratory rate of the patient according to the preset encryption protocol, where the respiratory signal and the respiratory rate are determined by the respiratory signal detection device according to a chest fluctuation signal of the patient, the step 201 includes a step 2011, and the step 202 includes a step 2023.
This embodiment is characterized in that the respiration signal detection device analyzes the inspiratory phase, the expiratory phase and the respiration rate of the patient from the chest fluctuation signal.
Step 2011, the preset encryption protocol decrypts the first patient respiratory data to obtain the decrypted respiratory signal and respiratory rate.
In this step, because the respiratory signal detection device encrypts the respiratory signal and the respiratory frequency of the patient according to the preset encryption protocol to obtain the first patient respiratory data, the first patient respiratory data is decrypted according to the preset encryption protocol, that is, the decrypted respiratory signal and respiratory frequency of the patient, that is, the second patient respiratory data, can be obtained. The respiratory signal comprises an inspiratory phase and an expiratory phase of the patient;
step 2023, controlling the output gas flow according to the decrypted respiratory signal and respiratory frequency.

In the above specific embodiment, the respiratory signal monitoring device may also perform data processing, which first obtains the chest fluctuation signal of the patient, then obtains the respiratory signal and the respiratory frequency according to the chest fluctuation signal of the patient, then encrypts the respiratory signal and the respiratory frequency through a preset encryption protocol and sends the encrypted respiratory signal and respiratory frequency as the first patient respiratory data to the ventilation device, and the ventilation device performs data decryption to obtain the respiratory signal and the respiratory frequency of the patient.
Optionally, in a specific implementation manner, the method provided in this embodiment of the present application further includes, in step 202, step 2023 to step 2024.
Step 2023, when the second patient respiratory data continues for N respiratory cycles to be in a preset data range and data deviation between the patient respiratory data in the N respiratory cycles is in a preset deviation range, outputting the gas according to the first flow rate when the patient inhales, and outputting the gas according to the second flow rate when the patient exhales; wherein the second flow rate is less than the first flow rate.
In the step, a preset data range is a respiratory data range of normal respiration of a human body, N respiratory cycles are respiratory cycle numbers for judging whether the respiration of a patient is stable, N can be numerical values of three, four, five, six, seven and the like, and a preset deviation range is a respiratory numerical value fluctuation range for defining whether the respiratory data of the patient is stable; when the second patient respiratory data lasts for N respiratory cycles and is within the preset data range, the respiratory condition of the patient is normal; and the data deviation between the respiratory data of each patient in N respiratory cycles is in the preset deviation range, which indicates that the patient breathes uniformly and stably, so that the gas output is controlled according to a larger first flow rate when the patient inhales so as to meet the ventilation requirement of the patient, and the gas output is controlled according to a smaller second flow rate when the patient exhales so as to save the ventilation gas.
Specifically, after receiving a breathing signal, the ventilator starts to control the motor or the electromagnetic valve to output a certain flow rate, so that a high flow rate is generated during inspiration, a low flow rate is generated during expiration, and the flow rate error and the control stabilization time are less.
In practical application, whether the breathing data of the patient is stable is judged by judging whether the waveform data, the inspiration time and the breathing time of the patient between the initial N continuous breathing cycles are very close; and if the data are very close to each other, judging that the breathing data of the patient are stable, otherwise, judging that the breathing data of the patient are unstable.
Step 2024, controlling gas output according to a third flow rate when the second patient respiratory data does not last for N respiratory cycles to be within a preset data range, or when a data deviation between the respiratory data of the patients within the N respiratory cycles is not within a preset deviation range; wherein the third flow rate is greater than or equal to the first flow rate.
In the step, when the second patient respiratory data does not last for N respiratory cycles and is in a preset data range, the respiratory condition of the patient is abnormal; or the data deviation between the respiratory data of each patient in N respiratory cycles is not in the preset deviation range, which indicates that the respiratory fluctuation of the patient is larger, so that the gas output is controlled according to a larger third flow when the patient inhales, and the ventilation requirement of the patient is met.
Optionally, in a specific implementation manner, the method provided in this embodiment of the present application further includes step 2025 in step 202.
Step 2025, controlling gas output according to the third flow rate and sending an alarm signal when the second patient respiratory data exceeds the preset data range.
In the step, the preset data range is a breathing data range of normal breathing of a human body, and when the breathing data of the second patient exceeds the preset data range, the current breathing abnormality of the patient is indicated, so that the breathing of the patient is effectively assisted, the ventilation equipment is controlled to output gas with larger flow according to the first flow, and an alarm is sent to inform medical staff in time.
Wherein, the third flow rate can be the upper limit value of the flow rate gas which can be output by the device; the third flow rate may be determined according to a degree of the second patient respiratory data exceeding the preset data range, that is, the larger the second patient respiratory data exceeds the preset data range, the larger the third flow rate is.
