Method for detecting antibacterial effect of sterilizing agent and sterilizing agent storage device

Abstract

The invention discloses a method for detecting the antibacterial effect of a sterilizing agent and a sterilizing agent storage device. The method comprises the following steps of S1, preparation of atest sample; S2, preparation of a bacterial solution; S3, preparation of a bacterial suspension; S4, preparation of an inoculant solution; S5, bacterial colony counting and oscillation contact; S6, recording and result calculation; S7, conclusion obtaining. The device comprises a device body, a label is glued to the outer surface at the front end of the device body, an outlet column is fixedly installed on the outer surface at the upper end of the device body, a sealing cover is movably connected to the portion, close to the upper end, on the outer surface of the outlet column, and a scraper is fixedly installed on the outer surface at the upper end of the sealing cover. According to the method for detecting the antibacterial effect of the sterilizing agent and the sterilizing agent storage device, the accuracy of a detection result can be improved, the number of the bacterial passaging times can be effectively controlled, bacteria contamination or variation is avoided, and a high bacterial activity is maintained; besides, due to the arrangement of the scraper, it is convenient for a user to open a sealing film of an outlet.

Description

Technical field [0001] The invention relates to the field of bactericide detection, in particular to a method for detecting the antibacterial effect of bactericide. [0002] The invention relates to the field of storage devices, in particular to a sterilant storage device. Background technique [0003] Bactericide refers to a kind of reagent that has antibacterial effect on bacteria and fungi. The method to detect its antibacterial effect in textiles is usually the oscillation method; the existing antibacterial effect detection method and the antibacterial storage device are used to detect its antibacterial effect. The effect is not perfect in the experiment. First, the temperature used in the experiment is 24±1℃. If in summer, the room temperature will exceed 24±1℃. However, the shaking culture time of this antibacterial test is long, generally 18-24h shaking culture, and then adding The temperature is difficult to be constant due to the heat generated by the oscillation itself, ...

Problems solved by technology

[0003] Bactericide refers to a reagent that has an antibacterial effect on bacteria and fungi. The method for detecting its antibacterial effect in textiles is commonly used by the oscillation method; the existing detection method for the antibacterial effect of the bactericide and the storage device for the bactericide are tested by using the oscillation method. The effect experiment is not perfect. First, the temperature used in the experiment is 24±1°C. If it is in summer, the room temperature will exceed 24±1°C. However, the antibacterial test takes a long time to shake and cultivate. The heat generated by its own oscillation, the temperature is difficult to keep constant, and secondly, it is difficult to control the number of passages of bacteria during the experiment, which is prone to bacterial contamination or mutation, which reduces the activity of resistant bacteria and affects the level of its antibacterial performance, thus affecting the accuracy of the test results In addition, when the user opens the device for experimentation, the sealing film needs to be torn off by hand, which is easy to cause certain pollution to the operator
