Sterilization methods are commonly used in hospitals
High temperature sterilization:
1, pressure steam sterilization: exhaust and pre-vacuum two kinds of boiler
2, dry heat sterilization
Low temperature sterilization:
1, ethylene oxide sterilization (EO)
2, hydrogen peroxide plasma sterilization
3, low temperature formaldehyde sterilization
Product categories
Pressure steam sterilization indicator tape (with approval)
Pressure steam sterilization instruction label (with approval)
Plasma Sterilization Chemical Indicator Card (no approval required)
Special adhesive tape for medical packing (no approval required)
Pressure Steam Sterilization Chemical Indicator Card (to be approved)
Ethylene oxide sterilization indicator tape (not approved)
BD test paper and BD bag
Structure of tape, label and card
Instruction: Ink
Base material: paper
glue
Spacer paper (release paper)
USES:
1. It is used to mark whether the package has been treated in the pressure steam sterilization process.
2. If the discoloration is uneven or incomplete, it can be suggested that the package has not been treated with qualified sterilization.
3, can record sterilization information (operator, sterilization period, package name, etc.)
Definition and use of indication cards in pressure steam sterilization kits
This product is a rectangular paper structure, printed with thermal dyes, composed of card, standard color block and indicator color block. The pressure steam sterilization indicator card is placed in the center of the package to be sterilized. After one sterilization cycle (132℃,3min), the color depth of the indicating color block on the card reaches or is deeper than that of the standard color block, indicating that the temperature reached and the temperature duration have met the requirements for sterilization. If it is lighter than the standard color block, it means that the temperature and temperature duration of action do not meet the requirements of sterilization. For packages that "do not meet the sterilization requirements", they cannot be used and should be re-sterilized.
Plasma sterilization chemical indications card
This product is a rectangular paper structure, printed with thermal dyes, composed of card, standard color block and indicator color block. Place the indicator card in the center of the package to be sterilized, and after one sterilization cycle, the color depth of the indicator color block on the card reaches or is deeper than that of the standard color block, indicating that the required conditions for sterilization have been met; If the color is lighter than the standard, it indicates that it does not meet the requirements of sterilization. For packages that "do not meet the sterilization requirements", they cannot be used and should be re-sterilized.
Suitable for low temperature plasma sterilizer
Brief introduction to BD test paper and BD package
Monitor the vacuum level and check for air leakage in the sterilizer
It is suitable for pre-vacuum sterilization pot. It can be used before sterilization operation every day
Placing position: above the sterilizing furnace exhaust air port
General requirements for tapes, labels, and cards
Appearance: indicating the ink is light yellow, clear and neat; The product is clean and the rubber surface is smooth and uniform.
Specification: Nominal width ±0.5mm; Length ≥ nominal value;
Viscosity: holding viscosity ≥8h:180° peel strength ≥5N/25mm
Tensile strength :≥50 N/25mm
Discoloration performance: the pre vacuum pressure steam (132 | 3) ℃, 3 ~ 6 min or discharge try to pressure steam (121 + 3) ℃, 20 min, indicating ink from light yellow to black;
Storage: Store in a dry and cool place at room temperature (10-30 ℃), avoid direct sunlight and acid-alkaline environment.
Indicates the cause of abnormal ink discoloration
Abnormal phenomena: no discoloration or shallow discoloration, uneven discoloration.
Causes of abnormality:
1. The local sterilization parameters of the sterilizer do not meet the requirements. The possible reasons are that the package is too large and too tight, the partial loading is too tight or a small amount of cold air remains in the package.
2, manufacturers of ink problems
3, the manufacturer is not uniform when printing ink
Sterilization effect monitoring method
Physical monitoring
The chemical monitoring
Biological monitoring
Combine the above methods
Chemical monitoring of sterilization quality
Chemical monitoring requirements:
Outside the package: indicating tape or indicating label should be used outside the package of each item to be sterilized. After one sterilization cycle, the color change should be observed to indicate whether it has been sterilized.
Inside the package: use a chemical indicator card, place it in the most difficult part to sterilize, and determine whether it meets the requirements of sterilization by observing the color change of the chemical indicator.
B-D test: it is suitable for the pre-vacuum sterilization pot. It is carried out before the sterilization operation every day. It can be used after monitoring the vacuum level and checking whether the sterilizer is qualified for air leakage
Application combination of packing tape and indicator tape, label and card
The first: sealing tape + package indicating label + package indicating card;
The second type: sealing tape + outside indicating tape + inside indicating card
The third kind: outside the package indicating tape + inside the package indicating card
