Cleaning and disinfection characteristics of medical injection pen holders

Easy cleaning process

When the injection pen holder needs to be cleaned after use, the smooth surface of PC material and the non-stickiness of PTFE work together to make cleaning work extremely easy. Usually, most stains can be cleaned with ordinary detergents and water. The surfactant components in ordinary detergents can reduce the adhesion between dirt and the surface of the holder, while the characteristics of PC and PTFE make it easier for dirt to fall off the surface under the action of detergents. During the cleaning process, gently wipe with a soft brush or cloth, just like wiping smooth glass, and the stains are quickly removed. Compared with brackets made of traditional materials, there is no need to use strong decontamination tools or special detergents, which avoids damage to the bracket due to excessive cleaning, and also reduces the potential harm that detergent residues may cause to the medical environment and human body.

Strong chemical corrosion resistance

In the medical environment, disinfection is the core link to prevent cross infection, and there are many types of disinfectants with strong chemical corrosion. Medical Injection Molding PC+20%GF+15PTEE Injection Pen Drum Holder shows excellent corrosion resistance when facing common disinfectants such as alcohol and chlorine-containing disinfectants. Alcohol, as a widely used disinfectant in medical places, has the characteristics of strong volatility and rapid sterilization. When alcohol acts on the PC+PTFE injection pen holder, it will not cause any erosion or dissolution on its surface. This is because the molecular structure of PC and PTFE is stable, and alcohol molecules cannot destroy their chemical bonds, thus ensuring that the integrity and performance of the holder are not affected. Chlorine-containing disinfectants, such as sodium hypochlorite solution, have strong oxidizing properties and can effectively kill various bacteria, viruses and other pathogens. However, its strong oxidizing properties also pose challenges to many materials. But the PC+PTFE holder can cope with it calmly. Even if it is immersed in a chlorine-containing disinfectant solution for a long time, the surface of the holder remains smooth as before, without discoloration, deformation or material decomposition. This strong chemical corrosion resistance ensures that the stent always maintains good physical properties and sanitary conditions during frequent disinfection, providing a solid guarantee for the long-term safety and stability of the medical environment. ​
Adaptability to various disinfection methods​
High-temperature and high-pressure steam disinfection​
High-temperature and high-pressure steam disinfection is a commonly used and efficient disinfection method in the medical field. Its principle is to use the steam generated by high temperature and high pressure to penetrate the cell wall and cell membrane of microorganisms to denature proteins, thereby achieving the purpose of killing microorganisms. For the PC+PTFE injection pen holder, it can perfectly adapt to this disinfection method. The PC material itself has high heat resistance and can still maintain a stable physical form in a high temperature environment without softening or deformation. The high temperature resistance of PTFE is even better, and it can withstand high temperatures without decomposition. In high-temperature and high-pressure steam disinfection equipment, the general disinfection temperature can reach 121℃ or even higher, and the pressure is also correspondingly high. Under such conditions, the PC+PTFE material stent can successfully complete the disinfection process, and its dimensional accuracy and surface properties have no obvious changes after disinfection, ensuring safety and reliability when used again.​
Chemical immersion disinfection​
Chemical immersion disinfection is also one of the common disinfection methods. As mentioned above, PC+PTFE material has good tolerance to common chemical disinfectants. When performing chemical immersion disinfection, the injection pen holder bracket is completely immersed in a disinfectant solution prepared according to the specified concentration, such as a hydrogen peroxide disinfectant solution. The disinfectant molecules react chemically with microorganisms to destroy their cell structure and metabolic function, thereby achieving the disinfection effect. Due to the chemical stability of PC and PTFE, during the immersion process, the bracket material will not react chemically with the disinfectant, no harmful substances will be dissolved, and the disinfection efficacy of the disinfectant will not be affected. After the specified time of immersion, take out the bracket and rinse it with clean water to achieve the purpose of thorough disinfection, and the bracket can continue to be used normally without shortening its service life due to chemical immersion. ​
Ultraviolet disinfection
In some special cases, such as certain environments that are sensitive to high temperatures or chemicals, ultraviolet disinfection may be used. Although the main advantage of the PC+PTFE injection pen holder is its good adaptability to traditional cleaning and disinfection methods, if the design of the holder allows it to be fully exposed to ultraviolet light, it can also be disinfected to a certain extent by ultraviolet light. Ultraviolet light can destroy the DNA structure of microorganisms, causing them to lose their ability to reproduce and survive. PC material has a certain tolerance to ultraviolet light, and will not experience obvious aging or performance degradation under short-term and moderate ultraviolet light exposure. PTFE also has good weather resistance and strong resistance to ultraviolet light. In scenarios where the conditions for ultraviolet disinfection are met, the PC+PTFE injection pen holder can also be disinfected by ultraviolet light, further enriching its choice of disinfection methods and providing more possibilities for the sanitation of the medical environment. ​
