Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, which are for the purpose of brevity and clarity, and which do not themselves indicate the relationship between the various embodiments and/or arrangements discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Example 1:
referring to fig. 4, a sterilizing cabinet comprises a cabinet body 1, a glass partition plate 2 and a plurality of sterilizing lamps 4, wherein the cabinet body 1 is of a square structure, the inside is a sterilizing zone of a hollow structure, a cabinet door 3 is arranged on the front side of the cabinet body 1, a plurality of sterilizing lamps 4 are arranged in the cabinet body 1, at least one sterilizing lamp 4 is arranged on each wall surface in the cabinet body 1, at the same time, at least one sterilizing lamp 4 is also arranged on the cabinet door 3, and the luminous surfaces of all the sterilizing lamps 4 can irradiate on the glass partition plate 2.
The glass partition plate 2 is arranged in the middle of the cabinet body 1, and in this embodiment, the glass partition plate 2 is selected to be a glass partition plate, and the light transmission wavelength range of the glass partition plate 2 is 220nm-2500nm, and the light transmission is more than 90%. In this embodiment, by providing a plurality of sterilizing lamps 4 on the outer periphery of the glass partition plate 2, respectively, each face of the article to be sterilized can be irradiated.
The ultraviolet light can penetrate the glass partition board 2 within the wavelength range of 185nm-400nm, and the peak value of the light wavelength of the sterilizing lamp 4 is 245nm, so that the glass partition board 2 can be used for passing the ultraviolet light with the wavelength of 220nm-400nm, and the peak value of the ultraviolet light can also pass.
When the glass separator 2 was selected, the following two sets of tests were performed:
a first group: and placing the object to be tested, on which pathogens are not smeared, in a sterilizing cabinet, and irradiating the object to be tested under ultraviolet light for 40min in batches for sampling, wherein the materials of the glass partition plates used in different batches of tests are quartz glass, 5mm toughened glass and 10mm toughened glass respectively.
Second group: the articles to be measured coated with pathogens and organic matters are divided into a plurality of groups, the articles to be measured are sampled after being irradiated for 40min in batches, and the glass partition plate materials used in each batch are quartz glass, 5mm toughened glass and 10mm toughened glass respectively during irradiation.
The data in fig. 5 were obtained according to the two above-described sets of experiments. According to the data in fig. 5, both the control group pathogen and bacteria were positive, and the control was established. Under the condition that the organic matters exist on the object to be detected, the pathogen inactivation effect of ultraviolet light passing through the quartz glass is superior to that of 10mm toughened glass and 5mm toughened glass. In the state of no organic matter on the object to be detected, the ultraviolet light passes through the quartz glass to inactivate pathogens, while the ultraviolet light passes through the 10mm toughened glass and the 5mm toughened glass to inactivate pathogens.
In addition, under the condition that organic matters exist on the object to be detected, the inactivation effect of ultraviolet light passing through 10mm toughened glass and 5mm toughened glass on bacteria is obviously weaker than the inactivation effect of ultraviolet light passing through quartz glass on bacteria.
Example 2:
a disinfection method of a disinfection cabinet mainly aims at disinfecting electronic equipment entering an animal pasture area. Comprising the following steps:
the first step, the organic matters on the surface of the electronic equipment are cleaned in a wiping mode, and the cleaning method mainly comprises various organic matters stuck on the electronic equipment in the working process of staff and small amounts of organic matters secreted by sweat glands of human bodies.
And secondly, placing the object to be disinfected in a disinfection cabinet, and irradiating for 5-40 min by using a disinfection lamp.
Preferably, in the second step, the irradiation time of the sterilizing lamp is 8min-10 min. And the surface of the article to be sterilized is wiped with a 75% strength wine wiper or potassium hydrogen persulfate compound and wiped at least twice. When the potassium hydrogen persulfate compound is used for wiping the surface of an article to be disinfected, the ratio of the potassium hydrogen persulfate compound powder to water is 1:80-1:120 (the ratio is usually selected to be 1:100).
Example 3:
a method for verifying the disinfection capacity of a disinfection cabinet comprises the following steps:
s10, selecting a plurality of to-be-detected articles to be divided into 4 parts, wherein the number of the to-be-detected articles in each part is equal, and marking the 4 to-be-detected articles as P1, P2, P3 and P4 respectively.
S20, smearing pathogens on the P1, placing the P1 on a glass partition plate in a cabinet body, irradiating for a certain time through a sterilizing lamp, taking out and sampling to obtain a result U28.
S30, mixing pathogens and organic matters, smearing the mixture on P2, directly sampling the P2, and obtaining a comparison result U10; then wiping P2 with alcohol and sampling to obtain a result U11; p2 after being wiped by alcohol is placed into a cabinet body, and is sampled after being irradiated for a certain time under a sterilizing lamp, so that a result U12 is obtained; directly placing the P3 into a cabinet body without any treatment, irradiating for the same time by using a sterilizing lamp, and then sampling to obtain a result U14.
S40, smearing pathogens and organic matters on the P4, wiping the P4 by using a potassium hydrogen persulfate compound, and sampling to obtain a comparison result U312; and then placing the P4 on a glass partition plate in the cabinet body, and sampling after a certain time of irradiation by a sterilizing lamp to obtain a result U38.
Specific:
in step S20, an organic-free test group is added in a mode of simulating pathogen (pseudorabies vaccine/escherichia coli), and the method comprises the following steps:
step S21, adding physiological saline into pathogens, uniformly mixing, smearing on P1, and sampling at P1 to obtain a result U20; the pathogen is mixed with the organic matter and diluted with physiological saline to form a thick liquid to form the control of step S20.
In step S22, the part P1 is placed under a sterilizing lamp to be irradiated for 20min, and then sampled, so as to obtain a result U28.
In step S23, another part P1 is placed under a sterilizing lamp to be irradiated for 40min, and then sampled, thereby obtaining a result U29.
Step S24, according to the mode of steps S12-S15, the following data are obtained: sampling result U21 of P1 coated with pathogens and organic matters by alcohol wiping twice; the P1 coated with pathogens and organic matters is wiped twice by alcohol and then irradiated for 20min under ultraviolet light, and then a result U22 is sampled; the P1 coated with pathogens and organic matters is wiped twice by alcohol and is irradiated for 40min under ultraviolet light, and then a result U23 is sampled; p1 coated with pathogens and organic matters is directly irradiated under ultraviolet light for 20min, and then a result U26 is sampled; the results U27 were sampled after the pathogen and organic coated P1 was directly irradiated under UV light for 40min.
S25, after the P1 coated with pathogens and organic matters is wiped by clear water, the sample is taken after 20 minutes of irradiation under ultraviolet light; the P1 coated with pathogens and organic matters is wiped by clean water and then irradiated for 20min under ultraviolet light, and then the result U25 is sampled.
In step S20, a pathogen test group without organic matters is added, and the pathogen positive control without organic matters is not established. From the data shown in fig. 2, it can be seen that the bacterial results were negative for all the experimental treatment groups. In the organic pathogen group, direct ultraviolet irradiation is performed for 20min without wiping and ultraviolet irradiation is performed for 40min after clear water wiping, and the detected part P1 is positive and suspected to be shielding of organic substances, so that pathogens caused by the fact that ultraviolet light cannot penetrate the organic substances are not inactivated.
Step S30 includes the steps of:
step S31, mixing the pathogen and the organic matters, and diluting with normal saline to form thick liquid;
and S32, coating the thick liquid on the P2, airing the P2 for 10min, and sampling the P2 to obtain a comparison result U10.
In step S33, the alcohol wipes P2 in S32 twice, and samples are taken, thereby obtaining a result U11.
And step S34, placing the P2 in the step S33 in a disinfection cabinet, and sampling after irradiation by a disinfection lamp to obtain a result U12.
And step S35, placing the P3 in a disinfection cabinet, and sampling after irradiation by using a disinfection lamp to obtain a result U14.
The step S34 includes: step S341, irradiating the part P2 sterilizing lamp passing through the step S33 for 20min, and then sampling to obtain a result U12; and S342, irradiating the other part of the P2 sterilizing lamp which passes through the step S33 for 40min, and sampling to obtain a result U13.
The step S35 includes: step S351, directly irradiating the part P3 by a sterilizing lamp for 20min, and sampling to obtain a result U14; step S351, another part P3 is irradiated by a sterilizing lamp for 40min, and the result U15 is obtained by sampling.
Referring to the test data of step S30 shown in fig. 1, it can be derived that: 1. the bacterial positive control was established, and the positive result was found in the test treatment group, so that the pathogen was judged positive. 2. The method comprises the steps of wiping alcohol treatment and irradiation by a disinfection lamp after wiping alcohol, sampling viruses, wherein the ct value of 48h is larger than the ct value of 0h, the bacterial result is negative, and the objects positioned below the electronic equipment in an experimental group which is not directly irradiated by alcohol wiping are positive, so that the effects of irradiation after wiping with alcohol and single alcohol wiping are shown.
In step S40, the simulated pathogen arrangement without and with the presence of organic matter is the same as that of step S30 and step S20, and in step S40, the arrangement ratio of the potassium hydrogen persulfate complex solution is 1:100.
Step S40 includes the steps of:
in step S41, the pathogen and the organic matter are mixed and diluted by normal saline to form thick liquid, the thick liquid is smeared on P4, a control group is arranged, and sampling is carried out to obtain a result U35. Referring to step S21 in step S20, physiological saline is added to the pathogen, mixed uniformly, smeared onto P4, sampled to obtain a control group, and the sampling result is U31.
Step S42, wiping the potassium hydrogen persulfate compound solution twice with P4 in the step S41, and sampling to obtain a result U312;
in step S43, the P4 after wiping the potassium hydrogen persulfate compound solution in step S42 is divided into three groups, and the obtained groups are irradiated under ultraviolet light for 5min, 10min and 20min, and the sampling results U36, U37 and U38 are recorded.
In step S44, the P4 without organic matter is placed under ultraviolet light to irradiate for 5min, 10min and 20min, and the sampling results U32, U33 and U34 are recorded respectively.
And S45, wiping the P4 smeared with pathogens and organic matters twice by alcohol, sampling and recording the result as U313, dividing the objects to be detected after wiping the alcohol into three groups, respectively placing the three groups under ultraviolet light for irradiation for 5min, 10min and 20min, and respectively recording the sampling results as U39, U310 and U311.
From the data shown in fig. 3, it is possible to obtain, in step S40, a further reduction in the irradiation time of the test group and wiping with a potassium hydrogen persulfate complex solution conventionally used in actual production. Both pathogens and bacteria were positive, and the control group was established. The bacteria test groups are negative, the ct value of the pathogen test groups is increased compared with 0h for 48h, and the result shows that organic matters are important influencing factors of ultraviolet sterilization, so that before ultraviolet light is irradiated, organic matter residues on the surface of the electronic social security are necessary to be removed.
In this example, a virus sample infects PK-15 cells, and a result of determination of Ct value is detected in pathogenic nucleic acid in cell supernatants at an initial stage and after 48-h infection. Bacterial samples were plated for blue and white differential culture.
In this example, the alcohol wiper used was alcohol cotton with a concentration of 75%. All are placed in a disinfection cabinet for ultraviolet irradiation.
In conclusion, after the organic matters are removed, pathogenic microorganisms on the surface of the object to be detected can be killed by ultraviolet irradiation for 5-40 min. The ultraviolet irradiation sterilization can greatly shorten the sterilization time of the to-be-tested object and reduce the damage of the to-be-tested object caused by fumigation sterilization. According to the test result and in combination with the actual use scene, the object to be tested is sterilized mostly when personnel enter the isolation center or the pig farm is bathed, the irradiation time is recommended to be 8-10 min, the loss of the ultraviolet lamp tube can be increased due to the long-time irradiation, and the replacement cost of the ultraviolet lamp tube is increased.
The foregoing examples merely illustrate specific embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
