[0030] [First embodiment]

[0031] For details, see Figure 1 , which shows a calibration method for detecting humidity in a sterile isolation environment provided by the first embodiment of the present invention, for example, including:

[0032] S11: Obtain the internal saturated water vapor pressure of the sterile isolation area through the temperature detected by the temperature sensor;

[0033] S13: obtaining the water vapor partial pressure of hydrogen peroxide in the sterile isolation area through the detection concentration of the hydrogen peroxide concentration sensor;

[0034] S15: Obtaining the water vapor partial pressure of the sterile isolation area by detecting the humidity of the coated humidity sensor and the internal saturated water vapor pressure;

[0035] S17: Calculating the mixed humidity of water vapor and hydrogen peroxide in the sterile isolation area according to the internal saturated water vapor pressure, the hydrogen peroxide water vapor partial pressure and the water vapor partial pressure;

[0036] S18: Correcting the display humidity of the display according to the mixed humidity so that the display displays the corrected display humidity.

[0037] Specifically, the correction method for detecting humidity in a sterile isolation environment provided by an embodiment of the present invention is used, for example, to correct the detected humidity of a humidity sensor in a sterile isolation environment in an isolator. For example, the isolator is, for example, a device having a sterile isolation chamber, and the sterile isolation area has, for example, a sterilized isolation environment of hydrogen peroxide, and has a large amount of hydrogen peroxide. The isolator is provided with, for example, a temperature sensor, a hydrogen peroxide concentration sensor, and a coated humidity sensor to detect the temperature, hydrogen peroxide concentration, and humidity in the sterile isolation area, respectively. It should be noted that the temperature sensor, the hydrogen peroxide concentration sensor, and the coated humidity sensor are, for example, sensors commonly used in the prior art, and the present application does not impose more restrictions on this. The isolator is also provided with, for example, a display, and the display is, for example, a display unit. For example, before correcting the displayed humidity of the display, the displayed humidity of the display is, for example, the detected humidity of the coated humidity sensor, and the processor executes the correction method for detecting humidity in a sterile isolation environment of the present application to correct the displayed humidity of the display so that the corrected displayed humidity is displayed on the display, and the corrected displayed humidity can, for example, reflect the real humidity in the sterile isolation area in the isolator. It should be noted that the actual humidity in the sterile isolation area mentioned here is, for example, the mixed humidity of water and hydrogen peroxide in the sterile isolation area.

[0038] The method for correcting humidity in a sterile isolation environment provided in an embodiment of the present invention obtains the internal saturated water vapor pressure, hydrogen peroxide water vapor partial pressure and water vapor partial pressure of a sterile isolation area in an isolator, and calculates the mixed humidity of water vapor and hydrogen peroxide in the sterile isolation area through the three, and then uses the mixed humidity to correct the displayed humidity of a coated humidity sensor, thereby achieving that the coated humidity sensor can accurately detect the mixed humidity of water and hydrogen peroxide under hydrogen peroxide sterilization conditions, thereby solving the problem in the prior art that there is a large gap between the displayed humidity of the coated humidity sensor and the actual humidity inside the sterile isolation area in the isolator.

[0039] Among them, see Figure 2 , step S11 specifically includes:

[0040] S112: Acquire the detected temperature of the temperature sensor;

[0041] S114: Calculate the internal saturated water vapor pressure of the sterile isolation area according to the detected temperature.

[0042] Specifically, the temperature sensor obtains the current temperature in the sterile isolation area (that is, the detected temperature of the temperature sensor), and the processor obtains the detected temperature T of the temperature sensor, which is related to the internal saturated water vapor pressure P. ws(T) There is a positive correlation. That is, as the detection temperature T increases, the internal saturated water vapor pressure P ws(T) Increase, the internal saturated water vapor pressure Pws(T) For example, it is the water vapor pressure when the water vapor reaches saturation. The processor calculates the internal saturated water vapor pressure P according to the detection temperature T using the internal saturated water vapor pressure calculation formula ws(T) Among them, the calculation formula for the internal saturated water vapor pressure is:

[0043] P ws(T) =6.1121*EXP((18.678(T / 257.14))*T / (T+257.14))+0.08

[0044] Furthermore, see Figure 3 , step S13 specifically includes:

[0045] S132: Acquire the detection concentration of the hydrogen peroxide concentration sensor;

[0046] S134: Calculate the water vapor partial pressure of hydrogen peroxide in the sterile isolation area according to the detected concentration.

[0047] Specifically, the hydrogen peroxide concentration sensor obtains the current hydrogen peroxide concentration in the sterile isolation area (that is, the detection concentration of the hydrogen peroxide concentration sensor), and the processor obtains the detection concentration C of the hydrogen peroxide concentration sensor, and calculates the hydrogen peroxide water vapor partial pressure P according to the detection concentration C using the hydrogen peroxide water vapor partial pressure calculation formula. wH2O2 , where the calculation formula for hydrogen peroxide water vapor partial pressure is:

[0048] P wH2O2 =0.00000001*C 3 -0.00001*C 2 +0.0221*C+0.6271

[0049] It should be noted that the above-mentioned hydrogen peroxide water vapor partial pressure calculation formula is derived based on the known concentration and coefficient based on the Raoult principle, and the derivation process will not be further elaborated here.

[0050] As mentioned above, see Figure 4 , step S15 specifically includes:

[0051] S152: Acquire the detected humidity of the humidity sensor with coating;

[0052] S154: Calculate the water vapor partial pressure of the sterile isolation area according to the humidity detected by the coated humidity sensor and the internal saturated water vapor pressure.

[0053] Specifically, the coated humidity sensor obtains the current humidity in the sterile isolation area (that is, the detected humidity of the coated humidity sensor), and the processor obtains the detected humidity RH (%) of the coated humidity sensor, and calculates the detected humidity RH and the internal saturated water vapor pressure P according to the detected humidity RH and the internal saturated water vapor pressure P. ws(T) The water vapor partial pressure P is calculated using the water vapor partial pressure calculation formula. wH2O , where the water vapor partial pressure calculation formula is:

[0054] P wH2O =(RH / 100)*P ws(T)

[0055] Further, see Figure 5 , step S17 specifically includes:

[0056] S172: Calculating a mixed gas pressure according to the hydrogen peroxide water vapor partial pressure and the water vapor partial pressure;

[0057] S174: Calculate the mixed humidity according to the mixed gas pressure and the internal saturated water vapor pressure.

[0058] Specifically, the processor uses, for example, a mixed gas pressure calculation formula according to the hydrogen peroxide water vapor partial pressure P wH2O2 and the water vapor partial pressure P wH2O Calculate the mixed gas pressure P wH2O2+H2O For example, the partial pressure of hydrogen peroxide water vapor P wH2O2 and the water vapor partial pressure P wH2O Add together to get the mixed gas pressure P wH2O2+H2O , the mixed gas pressure calculation formula is as follows:

[0059] P wH2O2+H2O =P wH2O2 +P wH2O

[0060] Based on the above, the processor uses, for example, a mixed humidity calculation formula according to the mixed air pressure P wH2O2+H2O and internal saturated water vapor pressure P ws(T) The mixed humidity RS (%) is calculated. The mixed humidity RS (%) is calculated as follows:

[0061] RS(%)=100*P wH2O2+H2O / P ws(T)

[0062] In addition, see Figure 6 , the calibration method for detecting humidity in a sterile isolation environment also includes, for example:

[0063] S191: Acquire the detected humidity of the humidity sensor without coating;

[0064] S193: Compare the humidity detected by the uncoated humidity sensor with the calibrated displayed humidity.

[0065] The processor, for example, obtains the test humidity of the uncoated humidity display as a control group, and compares the detected humidity of the uncoated humidity sensor with the calibrated displayed humidity displayed on the display to verify and compare the calibrated displayed humidity. For example, an uncoated humidity display is provided in the isolator.

[0066] The first embodiment of the present invention provides a method for correcting humidity in a sterile isolation environment by obtaining the internal saturated water vapor pressure, hydrogen peroxide water vapor partial pressure and water vapor partial pressure of the sterile isolation area in the isolator, and calculating the mixed humidity of water vapor and hydrogen peroxide in the sterile isolation area through the three. The mixed humidity is then used to correct the displayed humidity of the coated humidity sensor, thereby enabling the coated humidity sensor to accurately detect the mixed humidity of water and hydrogen peroxide under hydrogen peroxide sterilization conditions, thereby solving the problem in the prior art that there is a large gap between the displayed humidity of the coated humidity sensor and the actual humidity inside the sterile isolation area in the isolator.

[0067] In order to better illustrate the advantages and effects of the correction method for detecting humidity in a sterile isolation environment provided by an embodiment of the present invention, an example of the actual application of the correction method for detecting humidity in a sterile isolation environment provided by an embodiment of the present invention is given. Specifically, the correction method for detecting humidity in a sterile isolation environment provided by an embodiment of the present invention can be applied to the isolator of Chutian Technology Co., Ltd. Among them, Table 1 records the temperature and humidity related data of the isolator over a period of time.

[0068] Table 1 Temperature and humidity related data of isolator

[0069]

[0070] Taking the data in the above-mentioned embodiment 1 as an example, the specific formula derivation method of the correction method for detecting humidity in a sterile isolation environment provided in the embodiment of the present invention is illustrated.

[0071] First, the internal saturated water vapor pressure P is calculated by detecting the temperature T ws(T) ;

[0072] P ws(T) =6.1121*EXP((18.678(31.3 / 257.14))*31.3 / (31.3+257.14))+0.08=45.9

[0073] Secondly, the hydrogen peroxide water vapor partial pressure P is calculated based on the detected concentration C wH2O2 ;

[0074] PwH2O2 =0.00000001*0.3 3 -0.00001*0.3 2 +0.0221*0.3+0.6271=0.6

[0075] Furthermore, according to the detected humidity RH and internal saturated water vapor pressure P ws(T) Calculate the water vapor partial pressure P wH2O ;

[0076] P wh2O =(21.8 / 100)*45.9=10.0

[0077] Further, according to the hydrogen peroxide water vapor partial pressure P wH2O2 and the water vapor partial pressure P wH2O Calculate the mixed gas pressure P wH2O2+H2O ;

[0078] P wH2O2+H2O =0.6+10.0=10.6

[0079] According to the mixed gas pressure P wH2O2+H2O and internal saturated water vapor pressure P ws(T) The mixed humidity RS (%) is obtained by calculation.

[0080] RS(%)=100*10.6 / 45.9=23.1

[0081] It should be noted that only one decimal place is retained in the above calculations.

[0082] It can be clearly seen from the data recorded in Table 1 above that the mixed humidity calculated in the embodiment of the present invention is different from the detected humidity of the coated humidity sensor and the detected humidity of the uncoated humidity sensor. It can be obtained that the correction method for detecting humidity in a sterile isolation environment provided in the embodiment of the present invention is feasible and can correct the humidity in the isolator, and realizes that the coated humidity sensor can accurately detect the mixed humidity of water and hydrogen peroxide under hydrogen peroxide sterilization, which solves the problem of a large gap between the displayed humidity of the coated humidity sensor and the actual humidity inside the sterile isolation area of ​​the isolator in the prior art.
