[0029] 2. Preparation of spore suspension

[0030] Inoculate Bacillus subtilis on LB slant and culture for 72-96 hours, rinse with sterile saline to obtain bacterial suspension, suck the bacterial suspension into a sterilized conical centrifuge tube, inactivate the bacterial cells in a 75°C water bath for 30 minutes, and centrifuge for 10 minutes (500r / min), discard the sediment at the bottom of the tube, and observe it as a bacterial suspension containing spores through microscopic examination and staining. When the spore formation rate reaches more than 95%, follow-up experiments can be carried out. The spore suspension can be stored at 4°C for use, and the validity period is half a year. When the spore suspension is used, the live bacteria culture count should be carried out first.

[0031] 3. Preparation of disinfectant:

Embodiment 1

[0033] A disinfectant for waste in medical institutions, the raw material composition and mass ratio of the effective components of the bactericidal disinfectant are: 0.1% glutaraldehyde, 0.1% dodecyl dimethyl benzyl ammonium chloride, Didecyl dimethyl ammonium chloride 0.15%, sodium nitrite 1%, isopropanol 0.1%, camphor oil 0.01%, and the rest is distilled water; pH is adjusted to 7.0 by sodium bicarbonate.

[0034] A preparation method for a disinfectant for medical institution waste, comprising the following preparation steps:

[0035] S1: Measure or weigh the required materials according to the ratio requirements of each component;

[0036] S2: Pour a quantitative isopropanol solution through the drain, then pour dodecyldimethylbenzyl ammonium chloride through the drain, stir and mix at a low speed, and let stand;

[0037] S3: Pour into the weighed didecyl dimethyl ammonium chloride, stir and mix at a low speed, and let stand;

[0038] S4: Pour in the weighed glutaraldeh...

Embodiment 2

[0044] A disinfectant for waste in medical institutions. The composition and mass ratio of raw materials for making the active ingredients of the disinfectant are: 0.5% glutaraldehyde, 0.1% dodecyldimethylbenzyl ammonium chloride, bis Decyl dimethyl ammonium chloride 0.1%, sodium nitrite 1.5%, isopropanol 0.05%, camphor oil 0.05%, and the rest is distilled water.

[0045] The preparation method of the disinfectant in this embodiment is the same as that of Embodiment 1.

Abstract

The invention belongs to the field of composite disinfectants and discloses a disinfectant for medical institution wastes and a preparation method thereof. The disinfectant aims at solving the problems that an existing disinfectant is high in toxicity and has a corrosion inhibition effect on a carbon steel sheet. The invention discloses a disinfectant capable of being used for medical institutionwaste. Raw materials for preparing the effective components of the disinfectant comprise comprises by mass: 0.1 to 1.5 percent of glutaraldehyde, 0.05 to 0.1 percent of dodecyl dimethyl benzyl ammonium chloride, 0.01 to 0.15 percent of didecyl dimethyl ammonium chloride, 0.5 to 2 percent of sodium nitrite, 0.05 to 0.2 percent of isopropanol, 0.01 to 0.2 percent of camphor oil and the balance of distilled water. The preparation method comprises the following steps: measuring or weighing required materials according to the proportion requirements of the components, sequentially adding and mixing, adding sodium bicarbonate to adjust the pH value to 7.0, pouring quantitative cinnamomum camphora oil through a drainage device, and metering distilled water constant volume. The prepared compositedisinfectant is low in component content and low in toxicity, the influence of chemical components on human health and the environment is reduced to a great extent, and a stock solution of the composite disinfectant does not corrode metal such as aluminum, stainless steel and carbon steel.

Description

technical field [0001] The invention relates to the technical field of composite disinfectants, in particular to a disinfectant that can be used for waste in medical institutions and a preparation method. Background technique [0002] Medical waste is the first type of hazardous waste. Sampling tests show that medical waste contains a large amount of bacteria, and the number of E. coli is as high as 0.84×10 10 pcs / L, the total number of bacteria ranged from 8.65×10 5 ~8.121×10 10 pcs / g. Medical waste microorganisms mainly include bacteria, fungi, actinomycetes, viruses, mycoplasma, spirochetes, chlamydia, rickettsia, etc. Some of them are highly infectious, biologically toxic and corrosive, and have space infection, acute infection, cross Features such as infection and latent infection are extremely harmful. [0003] Medical waste is produced in the whole process of medical activities, and there are many kinds of complex and diverse types. The types of medical waste that...
