Definition And Use Of Sterilization Or Chemical Indicator

 Sterilization indicator tape and label  

Definition: Wrinkle paper or label paper as the base material, coated with color-changing ink as sterilization indicator, back coated with pressure sensitive adhesive.  The indicating tape used for chemical monitoring outside the pressure steam sterilization package, when reaching certain sterilization conditions 121℃, 20 minutes or 132℃, 3 minutes, the chemical indicating stripe on the back base of wrinkled paper will change from light yellow to black.  

USES:  

1. Used to mark whether the package has been treated by pressure steam sterilization process.  

2. If the discoloration is uneven or incomplete, it may indicate that the package has not been sterilized in accordance with the conditions.  

3, wrap the parcel (if no sealing tape is used).  

4, sterilization information can be recorded (operator, sterilization period, item name, pot, etc.).  

Chemical instruction card for plasma sterilization  

Definition: rectangular paper structure, printed with thermal dye, composed of card, standard color block and indicator color block.  Place the indicator card in the center of the package to be sterilized. After one sterilization cycle, the color depth of the indicator 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 it is lighter than the standard color block, it indicates that the sterilization requirements are not met.  Packages that "do not meet sterilization requirements" should not be used and should be re-sterilized.  

USES:  

1. Used to mark whether the article has been treated by hydrogen peroxide low-temperature plasma sterilization process.  

2. If the discoloration is uneven or incomplete, it may indicate that the article has not been sterilized in accordance with the conditions.  

3, suitable for low temperature plasma sterilizer.  

Chemical monitoring requirements for sterilization quality:  

Outside the package: each item to be sterilized should use indicating tape or indicating label outside the package. After one sterilization cycle, observe its color change to indicate whether it has been sterilized;  

Inside the bag: use the chemical indicator card and place it in the most difficult part to sterilize. By observing the color change of the chemical indicator, determine whether it meets the sterilization requirements.  

 

In the use of sterile articles, which situations are prohibited:  

Exceeds the prescribed period of validity;  

Loose packaging or torn fabric;  

The cloth is damp, stained, watermarked or waterstained;  

Indicates that the tape is not discolored or discolored unevenly;  

Sterilization equipment has stains, rust stains;  

Doubt about sterilization process and quality.

What is Self Seal Sterilization Pouches

  self seal sterilization pouches  is carried out in hospitals and medical or surgical sterilization manufacturing plants. Most packaging must be sterile when delivered to the end user. Medical self seal sterilization pouches provides protective envelopes for sterilization to protect against sterilization during disinfection, transportation, storage and delivery to the final home. Medical self seal sterilization pouches can assemble and secure several sterilization items required for a given surgical procedure and be ready for operation.   The term "sterilization" covers a wide range of products. A cotton ball, a cotton swab, and a tongue spatula are examples of "treatable products." Use them once and throw them away." Use once is not a synonym for cheap. Some very expensive sterilizations, such as dialysis filters, are themselves too fragile to be cleaned and reused after sterilization. To save costs, reuse is desirable. Most medical sterilization, such as sci

Reference Standard For Seal Verification of Sterilization Pouches For Medical Devices

With the increasing demand for  sterilization pouches  of medical devices, quality and safety inspection have become more and more stringent. sterilization pouches of medical devices (blister box +  tyvek roll  material,  sterilization paper bag , etc.) as a form of packaging directly in contact with the device and used to block microorganisms. No matter what form of packaging, it has two characteristics, which can meet the sterilization operation and remain sterile until the transportation conditions are used. Therefore, relevant departments began to focus on the review requirements of sterile packaging and make specific requirements for its performance and quality.   As we all know, GB/ t19633-2005 "packaging of ultimately sterilized medical devices" is one of the authoritative standards in the current sterile packaging standards. It is equivalent to iso11607-2003 "packaging of ultimately sterilized medical devices". Clarify the basic performance requirements of s

Medical Packaging Paper Market Demand "Accelerate Running"

  With the high demand for medical supplies in many countries around the world, the accelerated production of medical health materials and medical devices has also promoted the corresponding demand for supporting  sterile packaging  paper, and the medical packaging paper industry has also entered the "accelerated running".   It is understood that medical packaging paper is the paper packaging medical equipment, divided into medical dialysis paper and medical wrinkle paper. Among them, dialysis medical paper is widely used in surgical masks, medical gloves, disposable puncture instrument, kits, medical syringe hygiene materials and medical devices, such as, obviously, as the necessary raw materials, medical dialysis paper consumption is not too much less than those in surgical masks, this also caused the domestic specialty paper production enterprises inevitably enter work overtime to production operation. In fact, in recent years, due to environmental pollution problems and t
