Problems solved by technology

[0005] However, the color-changing ink used in the current verification device generally has the disadvantage of poor adhesion and is easily affected by steam. After use, the color-changing ink will fall off, causing pollution to surgical instruments, and the current verification device does not have traceability. Difficult to trace product information when a problem occurs

specific Embodiment 1

[0062] The indicator ink 2 is composed of the following components by mass percentage: 40% reactant; 5% developer; 20% adhesive; 5% antioxidant; 15% dilution solvent; 10% stabilizer; 5% glass fiber;

[0063] The indicator ink 2 is prepared by the following preparation process:

[0064] Step 1: Prepare materials, take the reactants, color developer, antioxidant, stabilizer, dilution solvent and adhesive according to the components and take them for later use;

[0065] Step 2: freezing at low temperature, respectively placing the release agent and the adhesive in a sealed container to freeze at low temperature to become solid;

[0066] Step 3: crushing and mixing, the solids obtained in step 2 are pulverized by a pulverizer in a low-temperature environment and then mixed, and fully mixed by a stirrer;

[0067] Step 4: heat up, step 3 continue to stir and mix and gradually increase the ambient temperature to room temperature, continue to stir for 40 minutes to obtain the base li...

specific Embodiment 3

[0084] Such as figure 2 with 3 As shown, in this embodiment, step 2 and step 3 are carried out in the integrated freezer and pulverizer.

[0085] The integrated freezing and pulverizing machine includes a freezing chamber 8, in which a freezing functional area and a crushing functional area are set, and the freezing functional area and the crushing functional area are connected by a material transmission device. The freezer 8 has a refrigeration function for ordinary industrial refrigerators, and its temperature adjustment range is 0-minus 24 degrees Celsius.

[0086] On the side wall of the freezing functional area, several freezing boxes 7 with cube-shaped freezing spaces are vertically arranged. The freezing box 7 is provided with a discharge cylinder 46 towards the end of the outer wall of the freezing functional area, and the freezing box 7 faces the inside of the freezing functional area. One end of the electric trapdoor 49 is provided with an electric trapdoor 49, an...

Abstract

The invention discloses a pressure steam sterilization five-class chemical indicator lumen verification device, which comprises a carrier layer, wherein indication ink is arranged on the carrier layer, an anti-steam coating is arranged on the surface of the indication ink, a back glue layer and an rfid traceability bar code are arranged on the carrier layer, and the indication ink is prepared from the following components in percentage by mass: 35-50% of a reactant, 2-10% of a color developing agent, 10-20% of an adhesive, 5-10% of an antioxidant, 10-20% of a diluting solvent, 5-10% of a stabilizer, and 2-5% of glass fiber. According to the invention, the formula and the production process of the indication ink are optimized, the formed indication ink is high in adhesion with the carrier layer, easy to adhere and form, sensitive in color development and good in indicating performance, the steam-proof coating is further arranged on the indication ink, and a transparent glass fiber material is introduced into the indication ink, so that the steam-proof capacity of the indication ink can be effectively enhanced, the situation that a large amount of the indication ink falls off after sterilization, and a small amount of the indication ink adheres to sterilized articles after sterilization is avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a lumen verification device for pressure steam sterilization of five types of chemical indicators. Background technique [0002] For sterilization supply centers or surgical supply rooms that use pressure steam sterilizers as the main sterilization equipment, we often add verification instruction cards containing chemical indicators, also known as five-category cards, to the pressure steam sterilization package. [0003] Generally, dense white paper card or milky white temperature-resistant plastic is used as the base material, and text information, LOGO and color-changing ink are printed on the base material as the sterilization indicator. [0004] The chemical indicator card in the pressure steam sterilization package can be used in the pre-vacuum pressure steam sterilizer. When packing, it needs to be placed in the center of the package to be sterilized, and then placed in th...
