Example 1
Referring to fig. 1, a flow chart of a ventilation control method is shown, which is applied to a ventilation device, which establishes a communication connection with a respiratory signal detection device, and which may specifically comprise the following steps 101-102.
The ventilation control method provided by the embodiment of the application is applied to the ventilation equipment, the ventilation equipment is connected to the nasal cavity of a patient through a breathing pipeline and a nasal oxygen tube, the patient carries a breathing signal detection device to breathe normally, and the ventilation equipment is started, and at the moment, the ventilation equipment outputs gas to the patient at a constant flow.
In the embodiment of the application, the ventilation equipment is in communication connection with the respiratory signal detection equipment, and the respiratory signal detection equipment is an external detection equipment, namely the respiratory signal detection equipment and the ventilation equipment are two independent equipment and do not share a processor; the respiratory signal detection device is responsible for acquiring respiratory data of a patient and transmitting the acquired respiratory data of the patient to the ventilation device. The respiratory 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 respiratory data of a patient are measured.
The 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 ventilation device may in particular be an open-air ventilation device.
Step 101, receiving first patient breathing data sent by the breathing signal detection device.
In this step, the first patient respiratory data is data related to patient respiration acquired by the respiratory signal detection device and sent to the ventilation device, and may be data processed through calculation, or may be raw data, where the first patient data includes, but is not limited to, a chest relief signal generated by the patient during inspiration and expiration.
Wherein, because the ventilation device establishes communication connection with the respiratory signal detection device, the respiratory signal detection device can send the data to the ventilation device when collecting respiratory data of a patient, and the ventilation device can receive the respiratory data of the patient sent by the respiratory signal detection device.
Step 102, controlling the output gas flow according to the first patient breathing data.
In this step, according to the actual breathing situation of patient that the first patient breathing data that above-mentioned breathing signal check out test set of external connection sent reflected promptly, the gas flow size of control output to make open gas circuit ventilation equipment carry for the patient gas flow can match with patient's demand, both avoided when patient's shortness of breath, ventilation demand are strong, the condition that ventilation gas flow is too little can not effectively assist patient to breathe, avoided when patient breathes smoothly, ventilation demand is weaker again, ventilation gas flow is too big causes the problem of gas waste.
The embodiment of the invention has the following advantages:
Receiving first patient breathing data sent by breathing signal detection equipment which is in communication connection with ventilation equipment; and controlling the output gas flow according to the first patient breathing data. Because respiratory signal check out test set and ventilation equipment are two independent equipments, this respiratory check out test set promptly is external check out test set, and it can accurately acquire patient's breathing data to give ventilation equipment with patient's breathing data transmission, then ventilation equipment can accurately carry out flow control to output gas according to this patient's breathing data, and then realizes accurate ventilation according to patient's actual respiratory condition.
Optionally, in one embodiment, the first patient respiratory data is encrypted data, and step 102 includes steps 201 to 202.
In this embodiment, in order to ensure data security, after detecting that actual respiratory data of a patient is obtained, the respiratory signal detection device encrypts the actual respiratory data according to a preset encryption protocol to obtain the respiratory data of the first patient, and then sends the respiratory data of the first patient to the ventilation device according to a preset communication protocol through the communication connection between the respiratory data of the first patient and the ventilation device, which is established in advance.
Step 201, decrypting the first patient breathing data according to a preset encryption protocol to obtain decrypted second patient breathing data.
The first patient respiratory data is encrypted by 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 the second patient respiratory data is identical to the patient's book respiratory data under the condition of no error of data transmission.
And 202, controlling the output gas flow according to the second patient breathing 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-type gas circuit ventilation device can be matched with the patient demand, and accurate ventilation according to the respiratory demand of the patient is realized.
In practical application, the breathing data of the second patient is also required to be checked, so that the consistency of the data sent by the breathing signal detection device and the data received by the ventilation device is ensured, and if the data are wrong, the ventilation device generates an alarm and always outputs high flow so as to ensure that the ventilation flow can meet the ventilation requirement of the patient.
Optionally, in a specific embodiment, the second patient respiratory data includes a chest relief signal of the patient, and the step 202 includes steps 2021 to 2022.
Step 2021, acquiring a respiratory signal and a respiratory frequency of the patient according to the chest relief signal.
In this step, the respiratory 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 rate of the patient according to the chest relief signal. The inspiration phase and the expiration phase correspond to inspiration and expiration respectively, the continuous inspiration and expiration are one breath, the respiratory frequency is the respiratory frequency generated in a preset time, and the preset time can be 1 minute.
Step 2022, controlling the output gas flow according to the respiratory signal and the respiratory frequency.
In the step, the ventilation gas flow is controlled in real time according to the received respiratory phase and respiratory 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 embodiment, the first patient respiratory data is obtained by encrypting, by a respiratory signal detecting device, a respiratory signal and a respiratory frequency of the patient according to the preset encryption protocol, where the respiratory signal and the respiratory frequency are determined by the respiratory signal detecting device according to a chest relief signal of the patient, the step 201 includes a step 2011, and the step 202 includes a step 2023.
In this embodiment, the respiratory signal detection device analyzes the inhalation phase, exhalation phase and respiratory rate of the patient from the chest relief signal.
And step 2011, decrypting the first patient breathing data by a preset encryption protocol to obtain decrypted breathing signals and breathing frequency.
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, the respiratory signal and the respiratory frequency of the patient after decryption can be obtained by decrypting the respiratory data of the first patient according to the preset encryption protocol, that is, the respiratory data of the second patient after decryption can be obtained. The respiratory signal includes 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 step, the ventilation gas flow is controlled in real time according to the received respiratory phase and respiratory frequency of the patient, so that the ventilation gas flow is saved on the premise of meeting the ventilation requirement of the patient.
In the above embodiment, the respiratory signal monitoring device may also perform data processing, firstly obtain a chest relief signal of the patient, then obtain a respiratory signal and a respiratory frequency according to the chest relief signal of the patient, and then encrypt the respiratory signal and the respiratory frequency through a preset encryption protocol and send the encrypted respiratory signal and respiratory frequency as respiratory data of the first patient 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 the embodiment of the present application further includes step 2023 to step 2024 in step 202.
Step 2023, controlling gas output according to a first flow rate when the patient inhales and controlling gas output according to a second flow rate when the patient exhales when the second patient breathes for N breathing periods are within a preset data range and data deviation between the patient breathing data within N breathing periods are within a preset deviation range; wherein the second flow rate is less than the first flow rate.
In the step, the preset data range is a respiratory data range of normal human respiration, N respiratory cycles are respiratory cycles for judging whether the respiration of a patient is stable, N can be three, four, five, six, seven and other values, and the preset deviation range is a respiratory value fluctuation range for defining whether the respiratory data of the patient is stable; when the respiratory data of the second patient are in a preset data range for N respiratory cycles, the respiratory condition of the patient is normal; the data deviation among the breathing data of each patient in N breathing periods is in a preset deviation range, which indicates that the breathing of the patient is uniform and stable, so that the gas output is controlled according to a larger first flow when the patient inhales to meet the ventilation requirement of the patient, and the gas output is controlled according to a smaller second flow when the patient exhales to save ventilation gas.
Specifically, after receiving the respiratory signal, the ventilation device starts to control the motor or the electromagnetic valve to output a certain flow, generates a high flow in the inspiration phase and generates a low flow in the expiration phase, and the flow error and the control stability time are required to be small.
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 between N continuous breathing periods just started by the patient are very close; if the respiratory data of the patient is very close, the respiratory data of the patient is judged to be stable, otherwise, the respiratory data of the patient is judged to be unstable.
Step 2024, controlling gas output according to a third flow rate when the second patient respiratory data does not last N respiratory cycles within a preset data range, or a data deviation between the patient respiratory data within 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 respiratory data of the second patient does not last for N respiratory cycles, the respiratory data of the second patient is in a preset data range, and the respiratory condition of the second patient is abnormal; or the data deviation between the breathing data of each patient in N breathing cycles is not in a preset deviation range, which indicates that the breathing fluctuation of the patient is large, so that the gas output is controlled according to a large third flow when the patient inhales, and the ventilation requirement of the patient is met.
Optionally, in a specific implementation, the method provided by the 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 out an alarm signal when the second patient respiratory data exceeds the preset data range.
In the step, the preset data range is the breathing data range of normal breathing of a human body, and when the breathing data of a 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, and the ventilation equipment is controlled to output a larger flow of gas according to the first flow, and an alarm is sent out to inform medical staff in time.
Wherein, the third flow rate can be the upper limit value of the gas of the flow rate which can be output by the equipment; the third flow may be determined according to the extent to which the second patient respiratory data exceeds the preset data range, that is, the greater the second patient respiratory data exceeds the preset data range, the greater the third flow.

Referring to fig. 3, a logic diagram of a ventilation control method according to an embodiment of the application is shown.
As shown in fig. 3, in step 301, a patient takes an open-gas ventilation device or the like and wears a respiratory signal detection device at a chest location, and then starts breathing;
in step 302, a respiratory signal detection apparatus acquires a respiratory signal and a respiratory frequency of a patient;
in step 303, the respiratory signal detection device is connected to the communication module and can normally communicate, otherwise, the communication module is detected again to try to communicate;
