Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, forms the application's a part, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 shows according to the flow chart of the alarm method that suffocates for anesthetic machine of first embodiment of the invention;
Fig. 2 is according to the block diagram of the alarm device that suffocates for anesthetic machine of second embodiment of the invention.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
The first embodiment
Fig. 1 shows according to the flow chart of the alarm method that suffocates for anesthetic machine of first embodiment of the invention.As shown in Figure 1, according to the alarm method that suffocates for anesthetic machine of the embodiment of the present invention, comprise the following steps:
Step S102, detects the pressure in the breathing pipeline of anesthetic machine every the scheduled time, and calculates the average pressure in scheduled time of predetermined number;
Step S104, compares average pressure and the first predetermined pressure;
Step S106, when average pressure is less than the first predetermined pressure, starts the first timing;
Step S108, when the first timing expires, if the average pressure during the first timing is all less than the first predetermined pressure, produces the warning that suffocates, and wherein, the first timing is greater than the scheduled time.
The average pressure of breathing pipeline according to the alarm method that suffocates for anesthetic machine of the embodiment of the present invention by detecting anesthetic machine in the scheduled time, then relatively this average pressure and predetermined pressure, finally according to comparative result, determine whether to produce and report to the police, so overcome, in correlation technique, only by detection of moisture amount, produce the problem of harm patient health of failing to judge that suffocating reports to the police may cause, and then reached the technique effect that is of value to patient health.
For example, when breathing pipeline disconnects, respiratory gas diaphragm may vibrate, cause the tidal volume detecting to be greater than predetermined tidal volume, thereby cannot detect the warning that suffocates, but when breathing pipeline disconnects, because breathing pipeline is communicated with atmosphere, so average pressure can be less.In addition, when the average pressure detecting is less than predetermined pressure, start the first timing, and the first timing by the time expires and just produces and report to the police, when the first timing expires, if the average pressure detecting exists the situation that is not less than this predetermined pressure, do not produce the warning that suffocates.So the embodiment of the present invention adopts average pressure to judge whether produce warning, can reach the technique effect of avoiding erroneous judgement.
Preferably, when average pressure equals the first predetermined pressure, also comprise: detect end expiratory positive pressure; End expiratory positive pressure and the second predetermined pressure are compared; When end expiratory positive pressure is less than or equal to the second predetermined pressure, start the first timing; When the first timing expires, if the average pressure during the first timing is equal to the first predetermined pressure, and end expiratory positive pressure is all less than or equal to the second predetermined pressure, produces the warning that suffocates, and wherein, the first timing is greater than the time of respiration gas.
Experiment discovery, when the average pressure detecting equals predetermined pressure, breathing pipeline is likely in normal state of ventilation, also likely in off-state, so increase the Rule of judgment of end expiratory positive pressure.End expiratory positive pressure refers in the each exhalation process of patient, is pressure values minimum in positive pressure.When pipeline disconnects, because pipeline is communicated with atmosphere, so minimum pressure is less than or equal to the second predetermined pressure; When pipeline normal ventilation, owing to there being patient's breathing in pipeline, so end expiratory positive pressure can not be less than or equal to the second predetermined pressure.In addition, when the end expiratory positive pressure detecting is less than the second predetermined pressure, also start the first timing, when the first timing expires, whether judgement, in this first timing, exists end expiratory positive pressure to be greater than the situation of the second predetermined pressure, if exist, do not produce the warning that suffocates.So, by adding end expiratory positive pressure as Rule of judgment, further avoided erroneous judgement.
Preferably, the scheduled time is 0.01 second, and predetermined number is 100, and the first predetermined pressure is 1 centimeter water column, and the second predetermined pressure is 0 centimeter water column, and when the respiratory frequency arranging on anesthetic machine is more than or equal to 6 beats/min, the first timing is 30 seconds; When the respiratory frequency arranging on anesthetic machine is less than 6 beats/min, the first timing is 35 seconds.
The scheduled time, predetermined number, the first predetermined pressure, the second predetermined pressure are experimental data, certainly, also other data can be set as required, for example, the scheduled time also can be set to 0.02 second, and predetermined number also can be set to 30, the first predetermined pressure also can be set to 1.1 centimeter water columns etc.In addition, the respiratory frequency arranging on anesthetic machine is limited between 4-12 time conventionally.
Preferably, alarm method also comprises: the tidal volume in the breathing pipeline of detection anesthetic machine; Tidal volume and predetermined tidal volume are compared; When tidal volume is less than predetermined tidal volume, start the second timing; When the second timing expires, if the tidal volume during the second timing is all less than predetermined tidal volume, produce the warning that suffocates.
When anesthetic machine is in manual mode lower time, owing to having operator by anesthetic machine, so conventionally there will not be in the situation that breathing pipeline disconnects, therefore can utilize tidal volume to judge whether patient suffocates.
Preferably, predetermined tidal volume is 20 milliliters/second, and the second timing is 60 seconds.
The in the situation that of manual mode, because patient has doctor at one's side, so time delay second timing of reporting to the police of suffocating can be greater than the first timing.
Alternatively, can utilize following code to realize the embodiment of the present invention:
