At the same time, the current active enzyme stored in the cleaning agent is in a liquid environment. As time goes by, the activity of the enzyme will drop significantly to about 70-80% of the initial level, resulting in a decline in cleaning power. Therefore, the cleaning effect is effectively guaranteed. The enzyme activity in the agent is also a difficult problem to be solved in the medical cleaning industry

[0025] Concrete preparation process is as follows:
[0026] (1) Seal liquid cleaning agent: mix polyoxyalkyl ether, detergency synergist, rust inhibitor, bactericide, chelating agent, water and solvent in a stirring tank to make a mixed liquid, and then mix the liquid Transfer to the mold A on the first molding machine, and use a water-soluble film to heat seal the liquid cleaning solution;
[0027] (2) seal the solid compound enzyme: in the mold B on the second forming machine, adopt water-soluble film to heat-seal mixed multiple biological enzyme powders;
[0028] (3) Preparation of solid cleaning agent:
[0029] 3-1: Preparation of solid matrix 3: Put alkali, soda ash, sodiummetasilicate, sodiumsulfate, sodium citrate, paraffin, polyethylene glycol and water into a stirred tank according to the configuration ratio, and put it at a temperature of 50-60°C Mix evenly; then put the mixed solution into the mold C capable of forming the first cavity 1 and the second cavity 2 ...
Embodiment 1
[0039] (1) Liquid chamber 1, comprising the components of the following mass fractions:
[0040]
[0041] (2) The multi-enzyme chamber (2) is 100% solid compound enzyme, and the solid compound enzyme is Novozymes CNS 8.0T.
[0042] (3) Further, the solid cleaning agent substrate (3) comprises the following mass fraction components:
[0043]
Embodiment 2
[0045] (1) Liquid chamber 1, comprising the components of the following mass fractions:
[0046]
[0047] (2) The multi-enzyme chamber (2) is 100% solid compound enzyme, and the solid compound enzyme is Novozymes Medley Essential 100T.
[0048] (3) Further, the solid cleaning agent substrate (3) comprises the following mass fraction components:
[0049]
[0050] The solid cleaning agent produced in the above two examples and the liquid multi-enzyme cleaning agent on the market were evaluated in terms of cleaning effect, chelation performance, and biofilm removal energy absorption. The results are shown in Table 2 below.
[0051]Cleaning effect evaluation method: place the diluted solution in a constant temperature shaker and heat it to 50 degrees Celsius, place the stf card, shake for 5 minutes, take it out for observation. Observe whether there is red, and judge the cleaning effect by the red stain removal time.
[0052] Chelating performance method: inject different ...

Abstract
The invention discloses a solidcleaning agent for medical equipment and a preparation method thereof. The solidcleaning agent comprises a solid base body with a stereoscopic structure; two independent containing cavities are arranged in the solid base body and include a first chamber for storing, sealing and covering a liquid cleaning agent and a second chamber for storing a solid complex enzymerespectively. The liquid cleaning agent and the solid complex enzyme are hotly sealed through a water-soluble thin film and then are put into the two containing cavities for storing the solid base body to prepare the solid cleaning agent. The prepared solid cleaning agent can be used for completely washing dirt on the surface of surgical equipment through a cooperative effect; meanwhile, the enzyme and other substances are separated, so that the enzyme in the cleaning agent can keep relatively high activity all the time. The solid cleaning agent produced by the invention also has the advantages of small volume, light weight, convenience for utilization, easiness for preservation and the like.
Description
technical field [0001] The invention belongs to the medical field, and in particular relates to a solid cleaning agent for medical instruments and a preparation method thereof. Background technique [0002] To prevent and control infection in hospitals, it is necessary to clean surgical instruments according to standard and strict procedures, which is the most important part of disinfection before sterilization and reprocessing of medical instruments. The cleaning of surgical instruments needs to be carried out in strict accordance with the process. The operation steps are washing, washing, rinsing, secondary rinsing with pure water, lubrication and drying. Before cleaning, many surgical instruments need to be manually pre-cleaned or ultrasonically cleaned to remove large pieces visible to the naked eye. dirt. In order to ensure the disinfection effect, the cleaning used in the current disinfection supply center needs to be configured proportionally on site, which increases...
