Embodiment 1

[0040] Such as figure 1 The cleaning effect monitoring card includes a stainless steel carrier 1 and a new type of simulated pollutant 2 .

[0041] The area of ​​the new simulated pollutant 2 is a square with a side length of 1 cm.

[0042] The length, width and height of the stainless steel carrier 1 are respectively: 40mm*20mm*1mm, the surface is treated by sandblasting process, and the roughness range is 120 mesh.

[0043] Preparation of simulated soil

[0044] The preparation method of the stained protein in the simulated blood stain is as follows: take fresh pig blood, add 0.1mol / L trisodium citrate for anticoagulation, centrifuge at 2000-3000 for 8 minutes, and take the supernatant as plasma. Then use saturated ammonium sulfate salting method to separate the plasma protein, put the separated plasma protein into the dialysis bag for dialysis for 24~48h (4℃), change the dialysis buffer every 3~6 hours, and then centrifuge the dialysate Take the supernatant an...

Abstract

The invention discloses a cleaning effect monitoring card for cleaning and disinfecting equipment and a preparing method thereof. The cleaning effect monitoring card comprises a novel simulant pollutant and a stainless steel carrier. The novel simulant pollutant is prepared from protein, starch and fat. As protein, starch and a chromogenic substance are connected through chemical bonds, the problem of binding fastness between a chromogenic substance and a stimulant substance on a traditional indicator card is solved fundamentally. Pig blood protein is adopted as the protein component in the simulant pollutant, and human body blood components are highly simulated. The novel stimulant pollutant prepared in the formula is printed on the stainless steel carrier according to a specific pattern to prepare the cleaning effect monitoring card, and the two characteristics of blood are simulated further. Blood after operation is dried up on the surface of a metal instrument, the dried blood cannot be thoroughly cleaned away with water, and therefore the purposes of high simulation and accurate indication of the whole cleaning effect monitoring card are achieved. The cleaning effect monitoring card is easy and convenient to use, and results are easy to judge and read. The cleaning effect monitoring card is free of blood products, safe, nontoxic and suitable for all cleaning processes.

Description

technical field [0001] The invention relates to a cleaning effect monitoring card for cleaning and disinfection equipment and a preparation method thereof. Background technique [0002] In the infection control of medical devices, the cleaning of devices is undoubtedly the most basic and important step, because residual pollutants will form biofilms, which will affect the quality of disinfection and cause sterilization failure. Residual contamination can also cause rust, corrosion, and damage to instruments, shortening their useful life. These pollutants are typically composed of carbohydrates, fats, and proteins. Our first job is to remove these substances before sterilization. [0003] In order to ensure the cleaning quality, some methods will be used to monitor the cleaning effect. In addition to the commonly used visual inspection, it can also be monitored regularly using cleaning test materials. [0004] The preparation of the cleaning effect monitoring card mainly l...
