Magnets for capillary tube mixing bars/fleas

Hi everyone,

We are looking to start using magnetic mixing bars/fleas for our capillary POC blood gas samples and I'm wondering how everyone manages the magnets.  Do they get reused?  I'd like the staff to mix immediately after collection so they would need the magnet at the bedside.  The magnets that I bought to trial the process are almost $3 each so it doesn't seem cost effective to use one per sample, but I also worry about infection prevention.  How do you navigate this?

Thanks!

When we used magnets/fleas, we reused the magnets. Now that staff immediately test the sample on the iStat at bedside, we don't require the flea/magnet.

We use disposable PICO Syringes that have the magnetic ball incorporated into the syringe (Radiometer ABL90).

Using magnetic mixing bars (or fleas) for capillary POC blood gas samples is a great idea for ensuring proper mixing and preventing clotting. Here are some considerations and best practices for managing the magnets:

  1. Reuse and Sterilization:

    • Reuse: Many facilities opt to reuse the magnets to keep costs down. After each use, the magnets can be cleaned and sterilized.
    • Sterilization: Ensure that the magnets are properly sterilized between uses to prevent cross-contamination. Autoclaving is a common method, but you should verify that the magnets you are using can withstand the process. Alternatively, chemical sterilization methods can be used.
  2. Infection Prevention:

    • Single-Use Covers: Consider using single-use sterile covers for the magnets. This can help maintain sterility while allowing for reuse of the magnets themselves.
    • Dedicated Magnets: Assign specific magnets to individual patients or specific areas to minimize the risk of cross-contamination.
  3. At the Bedside:

    • Accessibility: Keep a supply of sterilized magnets readily available at the bedside or in a nearby storage area to ensure that staff can mix samples immediately after collection.
    • Training: Provide training for staff on the proper handling and sterilization of the magnets to ensure compliance with infection control protocols.
  4. Cost Management:

    • Bulk Purchasing: Look into bulk purchasing options to reduce the cost per magnet. Some suppliers offer discounts for larger quantities.
    • Alternative Suppliers: Compare prices from different suppliers to find more cost-effective options. For example, RAM Scientific and Fisher Scientific offer various mixing components.

By implementing these practices, you can effectively manage the use of magnetic mixing bars while maintaining infection control and cost efficiency. How does this align with your current practices?
