Embodiment 1

[0023] (1) In a 100L stainless steel container, add 78kg of deionized water and 2kg of polyethylene glycol in sequence. The molecular weight of polyethylene glycol is 1 million, stir evenly at 50°C at a speed of 30 rpm, and then cool to room temperature;

[0024] (2) Add 4kg liquid lipase, 2kg liquid amylase, 2kg liquid cellulase, 2kg liquid pectinase and 10kg liquid protease in sequence, and stir evenly at a speed of 30 rpm to obtain a yellow-brown liquid, which is the present invention Compound enzyme preparation for cleaning medical instruments.

Embodiment 2

[0026] (1) In a 100L stainless steel container, add 29kg of deionized water and 1kg of polyethylene glycol in sequence. The molecular weight of polyethylene glycol is 2 million, stir evenly at 50°C at a speed of 30 rpm, and then cool to room temperature;

[0027] (2) Add 20kg of liquid lipase, 10kg of liquid amylase, 10kg of liquid cellulase, 10kg of liquid pectinase and 20kg of liquid protease in sequence, and stir evenly at a speed of 30 rpm to obtain a yellow-brown liquid, which is the present invention Compound enzyme preparation for cleaning medical instruments.

Embodiment 3

[0029] (1) In a 100L stainless steel container, add 90kg of deionized water and 5kg of polyethylene glycol in sequence. The molecular weight of polyethylene glycol is 3 million, stir evenly at 50°C at a speed of 30 rpm, and then cool to room temperature;

Abstract

The invention discloses a compound enzyme preparation for cleaning medical instrument. The compound enzyme preparation is composed of the following compositions in parts by weight: 1-5 parts of polyethylene glycol, 1-20 parts of a liquid lipase, 1-10 parts of a liquid amylase, 1-10 parts of a liquid cellulose, 1-10 parts of a liquid pectase, 1-10 parts of a liquid protease and the balance deionized water. The compound enzyme preparation for cleaning medical instrument is capable of preventing protease from decompose other biological enzymes, and also is capable of keeping the enzyme activity of protease and other biological enzymes. The compound enzyme preparation can be directly added into a conventional chemical cleaning agent in advance for forming a multienzyme cleaning agent, and also can be used directly after be prepared with a chemical cleaning agent, and the compound enzyme preparation has good cleaning effect when used to clean medical instruments.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a composite enzyme preparation for cleaning medical instruments and a preparation method thereof. Background technique [0002] The supply disinfection center of the hospital has to clean a large number of medical devices every day. These used medical devices will contain blood, mucus, tissue fluid, saliva and feces secreted by the human body. These dirt are mainly proteins and polysaccharides. , fatty and carbohydrate organic compounds, it is difficult to completely rinse off with only tap water. Thorough cleaning of medical devices after use to remove organic matter attached to them is an important part of preventing and controlling nosocomial infections and ensuring medical safety. If the medical device is not cleaned thoroughly, any organic matter remaining on it will form a protective layer on the surface of the microorganisms, hindering the contact between the disinfection and...
