reduce particulate contamination during infusion?

intravenous infusion is a commonly used clinical treatment in China, but the particles produced in the process of infusion can also cause serious harm to the human body, such as vascular embolism, granuloma, allergic reaction, cancerous reaction, pyrogen reaction, phlebitis, thrombocytopenia and so on. These pollution comes from the production process, air environment, liquid operation and so on. In recent years, the safety of infusion has attracted more and more attention. How to reduce the particle pollution in the process of infusion has gradually become one of the key points of infusion safety.

purify the air, conditions for the establishment of intravenous infusion deployment center. Primary hospitals that do not have an intravenous infusion deployment center must disinfect the treatment room before deployment to reduce unnecessary movement, and use circulating air ultraviolet air sterilizer, electrostatic adsorption air sterilizer, etc.

Disposable Infusion Set

1. Fully prepare medicine. Before using the disposable infusion liquid, carefully check whether the bottle label has expired, check whether the bottle cap is loose, whether the bottle body, bottle bottom and bottle label have cracks, and whether the liquid medicine has changes such as precipitation and discoloration.

2. Sterilize and wipe the ampoule after sawing. The grinding wheel is soaked in 75% alcohol glassware for standby, and 75% alcohol is used to disinfect the ampoule sawing place and neck after sawing, which can reduce the amount of particles in the ampoule liquid medicine. The glass ampoule control ampoule saw mark length ≤ 1/4 weeks, and sterilize the ampoule neck before opening, sterilize again after cutting saw and tilt 45 degrees to split, reducing liquid medicine pollution and glass particles.

3. Reduce operating steps. Disposable infusion sets need to repeatedly puncture the infusion bottle rubber plug or plastic plug in the dispensing process, which can easily cause debris to fall off, which is not only easy to cause needle blockage, but also increases the chance of debris entering the infusion bottle to cause infusion particle pollution.

4. Change the needle angle. Disposable infusion sets suggest that the needle bevel penetrates less rubber particles than the straight needle at 45 degrees, and that needles with smaller needles than larger needles produce less rubber particles.
