Fig. 2 illustrates a method for calibrating an auto-meter of a ventilator according to a second embodiment of the present invention. The second embodiment is a refinement of the first embodiment, and the method for calibrating the automatic measurement of the ventilator provided by the second embodiment comprises:
step S100, sending a calibration permission request to the ventilator 2;
step S101, receiving a calibration instruction fed back by a respirator according to a calibration permission request, and determining a working state according to the calibration instruction;

and step S105, outputting a calibration result according to the ventilation mode, the first working parameter, the second working parameter, the first measurement parameter and the second measurement parameter.
In this embodiment, when the calibration instruction is an authorized permission instruction, the operating state determined by the calibration apparatus 1 is a fully automatic operating state. The calibration device 1 determines a calibration item and related setting information corresponding to the calibration item according to a calibration strategy in a full-automatic working state, automatically sets a first working parameter, a ventilation mode and a second working parameter of the simulated breathing device of the breathing machine according to the related setting information, and simultaneously, the calibration device 1 automatically switches the first working parameter and the ventilation mode of the tested breathing machine 2 according to the calibration strategy in the full-automatic working state, so that a calibration result is automatically output when the ventilation mode, the first working parameter, the second working parameter, the first measurement parameter and the second measurement parameter are obtained. That is, when the calibration device 1 is in the fully automatic operating state, the user does not need to input parameters in person to set the first operating parameter of the ventilator 2, the ventilation mode, and the second operating parameter of the simulated breathing device, and the calibration device 1 is mainly used for automatic setting.
In this embodiment, the authorization permission instruction carries remote control information, and before setting the first operating parameter of the ventilator 2, the ventilation mode, and the second operating parameter of the simulated breathing apparatus 3 according to the calibration policy in the operating state, the method includes:
sending remote control information to a second communication interface of the breathing machine 2 through the first communication interface, wherein the remote control information is used for prompting the working mode of the breathing machine 2 to be adjusted to a to-be-calibrated mode; the first communication interface is an interface on the calibration apparatus 1.
In a specific use scenario, when the authorization permission instruction fed back by the ventilator 2 indicates that the ventilator 2 is the ventilator 2 capable of performing calibration, because the authorization permission instruction fed back by the ventilator 2 carries remote control information, which may be a calibration password, the calibration device 1 sends the calibration password to the second communication interface via the first communication interface, that is, the operating mode of the ventilator 2 can be adjusted to a to-be-calibrated mode via the calibration password, so as to implement a remote mode adjustment operation, that is, automatically set a first operating parameter and a ventilation mode that need to be involved in a calibration process of the ventilator 2.
In the present embodiment, before setting the first operating parameter of the ventilator 2, the ventilation mode, and the second operating parameter of the simulated breathing apparatus 3 according to the related setting information, the method includes:
sending verification request information to a third communication interface of the simulated breathing device 3 through the first communication interface, wherein the verification request information is a signal automatically generated after the first communication interface of the calibration device 1 and the third communication interface of the simulated breathing device 3 are connected through a wire;
detecting whether a verification success signal is received, wherein the verification success signal is a signal fed back by the simulated breathing device 3 according to the verification request information;
and if the verification success signal is received, setting the first working parameter of the breathing machine 2, the ventilation mode and the second working parameter of the simulated breathing device 3 according to the related setting information.
In a specific use scenario, when the first communication interface of the calibration device 1 is connected with the third communication interface of the simulated breathing device 3, verification request information is automatically generated, the calibration device 1 sends the verification request information to the simulated breathing device 3 through the first communication interface and the third communication interface for verification, the verification request information is used for verifying whether the simulated breathing device 3 is an automatically-calibrated simulated breathing device, obviously, when the simulated breathing device 3 feeds back a verification success signal according to the verification request information, the verification success signal is transmitted to the calibration device 1 through the third communication interface and the first communication interface, that is, the calibration device 1 can detect the verification success signal, the calibration device 1 can execute an automatic setting step in an automatic calibration process, that is, execute a first working parameter, a second working parameter, a third working parameter, a third working parameter working, And a ventilation mode and a second working parameter of the simulated breathing device 3 are set.
It should be noted that, when the accessed simulated breathing apparatus 3 is a simulated lung that can be controlled through the third communication interface, the second operating parameter of the simulated breathing apparatus can be automatically set according to the relevant setting information; when the connected simulated breathing apparatus 3 is a simulated lung without a third communication interface, the user needs to input information on a parameter setting interface of the simulated breathing apparatus 3 to manually set the second operating parameter.
The method for calibrating the automatic measurement of the breathing machine provided by the second embodiment further comprises the following steps:
when the calibration instruction is an unauthorized permission instruction, the working state is a semi-automatic working state, namely the semi-automatic working state is determined according to the unauthorized permission instruction;
step S111, determining each calibration item and related setting information corresponding to each calibration item in a full-automatic working state;
step S112, setting a first working parameter and a ventilation mode of the breathing machine 2 according to the related setting parameters;
step S113, sending first control information to the simulated breathing apparatus 3, wherein the first control information is used for triggering the simulated breathing apparatus 3 to output a parameter setting interface, and the parameter setting interface is used for receiving information input by a user so as to set a second working parameter of the simulated breathing apparatus 3;
step S114, acquiring a first measurement parameter and a second measurement parameter;
and step S115, outputting a calibration result according to the ventilation mode, the first working parameter, the second working parameter, the first measurement parameter and the second measurement parameter.
In this embodiment, when the calibration instruction command is an unauthorized permission command, the operating state determined by the calibration apparatus 1 is a semi-automatic operating state. The calibration device 1 automatically sets a first working parameter and a ventilation mode of the breathing machine 2 according to related set parameters, then sends first control information to the simulated breathing device 3, prompts the simulated breathing device 3 to output a parameter setting interface, and completes manual setting of a second working parameter of the simulated breathing device 3 after a user inputs information on the parameter setting interface of the simulated breathing device 3. That is, when the ventilator 2 feeds back an unauthorized permission instruction, it indicates that the ventilator 2 is a ventilator that has output a calibration result, and no automatic calibration is needed, and if further fine calibration is needed, the ventilator can only be personally attended by the user, and further calibration is performed by means of manual calibration. That is, when the calibration device 1 is in a semi-automatic working state, a part of the parameter settings need to be automatically set by the calibration device 1, and another part of the parameters need to be manually set by the user, specifically: the user needs to input parameters in person to manually set the second working parameter of the simulated breathing apparatus 3, and the first working parameter and the ventilation mode of the ventilator 2 are automatically set.
Specifically, the obtaining the first measurement parameter and the second measurement parameter includes:
sending an acquisition request to the breathing machine 2, and receiving a second measurement parameter of the first sensor fed back by the breathing machine 2 according to the acquisition request; the acquisition request is used for the ventilator 2 to send the second measurement parameter read by the first sensor to the calibration device 1, and the first sensor is arranged inside the ventilator 2;
and acquiring a first measurement value read by a second sensor, calculating a first measurement parameter according to the first measurement value, wherein the second sensor is connected with the calibration device 1 and is arranged in the gas pipeline.
In the present embodiment, the first measured parameter is a measured parameter obtained by calculating a first measured value obtained by a second sensor of the calibration device 1, and the second measured parameter is a parameter directly read by the first sensor inside the ventilator 2.
Fig. 3 illustrates a method for calibrating an auto-meter of a ventilator according to a third embodiment of the present invention. The third embodiment specifically refines the step of outputting the calibration result according to the ventilation mode, the first operating parameter, the second operating parameter, the first measurement parameter, and the second measurement parameter in the second embodiment, and the steps include:
step S1051, determining a first standard parameter and a second standard parameter corresponding to the ventilation module, the first working parameter and the second working parameter according to the related setting information;
in this embodiment, after the ventilation module, the first operating parameter, and the second operating parameter are obtained, the first standard parameter and the second standard parameter corresponding to the ventilation module, the first operating parameter, and the second operating parameter may be determined according to a calibration strategy. Since the relevant setting information included in the calibration strategy can be set with reference to the relevant regulations of JJF1234 "ventilator calibration standards", that is, the relevant setting information includes data matching a plurality of sets of ventilation modules, first operating parameters, second operating parameters, first standard parameters, and second standard parameters, the first standard parameters and the second standard parameters corresponding to the ventilation modules, the first operating parameters, and the second operating parameters can be screened out according to the obtained ventilation modules, the first operating parameters, and the second operating parameters.
Step S1052, calculating a first result value according to the first measured parameter and the first standard parameter, and calculating a second result value according to the second measured parameter and the second standard parameter; the first result value is the difference value obtained by subtracting the first standard parameter from the first measured parameter, and the second result value is the difference value obtained by subtracting the second standard parameter from the second measured parameter.
