Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Fig. 1 has shown a kind of embodiment of hydrogen peroxide sterilization method of the present invention, and this hydrogen peroxide sterilization method needs to keep injecting compressed air in isolator, also comprises the following steps:

[0026] S1. Detect the humidity inside the isolator and hydrogen peroxide concentration C;

[0027] S2. Inject the hydrogen peroxide solution into the heated evaporator, and pass the gas generated by the evaporation of the hydrogen peroxide solution into the isolator;

[0028] S3, set the humidity value like Then go to step S4, if Then return to step S2;

[0029] S4, stop injecting the hydrogen peroxide solution into the evaporator;

[0030] S5. Set the hydrogen peroxide sterilization concentration value of the sterilization state as C1, if C≥C1, then enter step S6, if C

Abstract

The invention discloses a hydrogen peroxide sterilization method which comprises the following steps: S1, detecting the humidity Phi inside an isolator, and the concentration C of hydrogen peroxide; S2, filling a hydrogen peroxide solution into a heated evaporation disc, and introducing a gas evaporated from the hydrogen peroxide solution into the isolator; S3, setting a humidity value as Phi 1, if Phi is greater than Phi 1, turning to step S4; if Phi is less than or equal to Phi 1, turning back to step S2; S4, stopping filling the hydrogen peroxide solution into the evaporation disc; S5, setting the sterilization concentration of hydrogen peroxide in a sterilization state as C1, if C is greater than C1, turning to step S6, if C is less than C1, turning back to step S2; S6, keeping the sterilization state till a set sterilization time T; S7, stopping detecting the humidity Phi inside the isolator and the concentration C of hydrogen peroxide, stopping heating the evaporation disc, stopping filling the hydrogen peroxide solution into the evaporation disc, and the like. The hydrogen peroxide sterilization method has the advantages that no coagulation can be caused and instruments and meters of sterilization equipment can work stably for a long time.

Description

technical field [0001] The invention relates to the field of medicine production, in particular to a hydrogen peroxide sterilization method. Background technique [0002] Existing hydrogen peroxide sterilization technologies mainly include the following three types: 1. Using evaporating trays to heat and evaporate liquid hydrogen peroxide solution to form steam, which is filtered through a high-efficiency filter and enters the isolator without any manual humidity control. , During the sterilization process, a large amount of hydrogen peroxide will condense inside the cavity to form a condensation surface; 2. Use a vaporization device to vaporize the hydrogen peroxide solution to form steam. After passing through the adsorption desiccant, most of the water vapor and a small part of the peroxide The hydrogen peroxide gas is adsorbed in the desiccant, and the relatively pure (containing a small amount of moisture) hydrogen peroxide gas is collected downstream. This part of the ...
