Background

For a sterilization supply center or an operation supply room using a pressure steam sterilization pot as a main sterilization device, verification indication cards containing chemical indicators, also called five types of cards, are often added into a pressure steam sterilization bag.

Compact white paper card or milky white temperature resistant plastic is generally used as a base material, and then character information, LOGO and color-changing ink are printed on the base material to be used as a sterilization indicator.

The chemical indicator card in the pressure steam sterilization bag can be used for a pre-vacuum pressure steam sterilizer, and when the chemical indicator card is packaged, the chemical indicator card needs to be placed in the center of a package to be sterilized and then placed in the sterilizer for sterilization quality monitoring in the pressure steam sterilizer article bag. When certain sterilization conditions are reached, the indicator strip on the white cardboard undergoes a significant color change, for example from off-white or pale yellow to black, which is generally achieved by means of a heat-sensitive color-changing ink.

However, the color-changing ink used in the existing verification device generally has the defects of poor adhesion, is easily influenced by steam, and causes pollution to surgical instruments when the color-changing ink falls off after use.

In view of this, we propose five classes of chemical indicator lumen verification devices for pressure steam sterilization.

The working process of the freezing and crushing integrated machine is as follows:

in an initial state, injecting the liquid material prepared in the step one into a liquid material bin; the piston 47 of the material ejection cylinder is in a contraction state, the electric trap door 49 is in a closing state, and the piston 47 of the material ejection cylinder and the electric trap door 49 seal and close two ends of the freezing box 7 to form a material storage space; the inner wall of the freezing box 7, the piston 47 of the discharging cylinder 46 and the electric trap door 49 are provided with anti-sticking layers, namely, the inner wall of the storage space has an anti-sticking function, and the solid materials after freezing are prevented from being pushed out easily. Starting the material injection pump and the material injection valve 6 to inject the liquid material in the liquid material bin into the material storage space along the material injection pipe 45 and the material injection hole; the freezing box 7 starts the freezing function to freeze the liquid material in the material storage space into a solid state; then the discharging cylinder 46 is started, the electric trap door 49 is opened, the piston 47 pushes the solid material block 48 to pass through the electric trap door 49, and then the solid material block enters the horizontal tray 10 of the vertical elevator 9 of the material conveying device, and the horizontal tray can support the solid material block 48 to move upwards, is placed on the transverse conveying belt 11 and is thrown to the transverse conveying belt 11.

Solid material blocks 48 are thrown into the coarse crushing bin 14 through a coarse material feeding port 15, the auger 13 is driven to rotate through a flood dragon driving motor 12, coarse crushing is carried out on the solid material blocks 48, the crushed materials are filtered through the sieve plate 16 with sieve holes at the bottom of each level of coarse crushing bin 14, and finally enter a fine crushing part through a fine material feeding port and respectively enter a left fine crushing bin 43 and a right fine crushing bin 18. Refrigeration pipelines 19 are arranged outside the left crushing bin and the right crushing bin in an all-around mode, and the problem that solid materials melt after being further crushed and refined can be solved.

The solid material that gets into left crushed aggregates storehouse 43 and right crushed aggregates storehouse 18 has been the graininess, under the separation of left broken discharge plate 39 and right broken discharge plate 44, only can follow left broken feed opening 38 and the unloading of right broken feed opening 22, and enter into the lower part of left broken discharge plate 39 and right broken discharge plate 44, and grinding toothed plate 23 on left broken discharge plate 39 and the right broken discharge plate 44, and install grinding toothed plate 23 on first abrasive knife 36 and second abrasive knife 24 and carry out the relative grinding, the material through the fine grinding falls through seting up the sieve mesh 25 on first abrasive knife 36 and second abrasive knife 24, and collect in the storage silo 30 through left feed opening 34 and right feed opening 28, and collect in the material box 31 under the discharge opening 32 bottom the center pillar 30.

When the materials in the left crushing bin and the right crushing bin are gradually reduced, the pressure applied to the left bin ejection spring 41 and the right bin ejection spring 20 is reduced, and the materials are gradually rebounded upwards; when the left bin material ejecting spring 41 and the right bin material ejecting spring 20 move upwards, the left bin material ejecting plate 40 and the right bin material ejecting plate 21 can be driven to move upwards around a far-end hinge point, and the surplus materials in the bin are gradually dumped towards the left crushing discharging hole and the right crushing discharging hole 22 until all the surplus materials are downwards led out. Through setting up this clear material structure, can avoid the clout to deposit in left crushed aggregates storehouse 43 and right crushed aggregates storehouse 18 to ejection of compact process is accelerated, avoids the clout to pile up and condenses.

This patent is through setting up freezing crushing all-in-one, collects freezing, transmission and smashes each item function in an organic whole of collecting the operation, realizes full automation in process of production, need not external intervention or the artifical linking between the flow of implementing and transports, avoids the material to produce secondary pollution at above-mentioned in-process. In addition, because the device is full-automatic integration degree is high, can keep the production quality and the purity of material, improves verification device's verification degree of accuracy and success rate.
