Description
Technical field
The invention belongs to endoscopy disinfection technical field, and in particular to a kind of sterilization method of fibrescope.
Background technology
Sterilization is the important step of diseases prevention and control, is also the important component for implementing policy of putting prevention first, especially
It is that in infectious disease control, sterilization has turned into one of key means of cut-out route of transmission, wherein due to fibrescope
Special circumstances, in order to avoid blood and mucus it is solid after be difficult to clean, using needing to clean immediately after finishing, cleaning
, it is necessary to which repeated multiple times cleaning, immersion, wiping, relatively cumbersome to ensure to sterilize completeness, accordingly, it would be desirable to a kind of simpler in journey
Change the sterilization method that can guarantee that Disinfection Effect simultaneously.
The content of the invention
The purpose of the present invention is that there is provided a kind of sterilization method of fibrescope the problem of being directed to existing.
The present invention is achieved by the following technical solutions：A kind of sterilization method of fibrescope, comprises the following steps：
（1）Fibrescope after is put into cleaning solution, is 22-40kHz in vibration frequency, power density is 60-80 μ
W/cm2, the cleaning solution is comprised the following raw materials by weight percent：Fraxinellone 2-3%, 1,2- propane diols 3-5%, Phenoxyethanol 1-
3%th, stabilizer 0.5-0.7%, allantoin 0.1%, surplus are deionized water；
（2）Fibrescope after above-mentioned primary wash is put into flowing water speed in 0.6m/s flowing water, flowing water temperature is 38-
45 DEG C, the part that will have pipeline in flushing process, including one end Parallel to the flow direction of intubation, tracheae, water pipe, hole pipe are fixed,
Current is passed through pipeline, keep taking out after rinsing 5-10 minutes；
（3）With the gauze wrapped fibrescope containing 50% ethanol, wherein the part for having pipeline uses the gauze containing 50% ethanol to fill,
With the hot blast drying that temperature is 40 DEG C, gauze is removed.
As further improvement of these options, the stabilizer is cadmium laurate, phosphorous acid hexichol one last of the ten Heavenly stems ester, 2,6-
D-tert-butyl-p-cresol compares 10 with weight:2:1 mixes.
As further improvement of these options, the preparation method of the cleaning solution is：Deionized water is heated to 75-
After 80 DEG C, Jia Ru fraxinellones, insulated and stirred 15-20 minutes；Then 50-55 DEG C is cooled to, 1,2-PD and stabilizer is added, stirs
Mix 20-25 minutes；It is down to normal temperature, adds surplus stock, stirring is produced to being completely dissolved.
As further improvement of these options, the gauze being wrapped in outside fibrescope is two layers, there is pipeline
Part fill full with gauze.
As further improvement of these options, the sterilizing operation process need to meet sterile working standard.
The present invention has advantages below compared with prior art：The blood on fibrescope can be effectively removed using this method
Liquid and mucus etc., select the power density adapted to, it is ensured that discharge dirt while not damaged fiber endoscope surface
Or cleaning is clean, using the gauze containing 50% ethanol, accelerates air drying process while can further sterilizing, accelerate fiber endoscopic
The disinfection of mirror, under the conditions of relative low temperature, makes the Microbial survival rate that its article pollutes reach sterilization assurance.
