Medical Bandage Manufacturing Process Flowchart

 

Process Flowchart Steps:

  1. Raw Material Selection:

    • Select appropriate fibers based on product requirements:

      • Cotton: For high absorbency.

      • Polyester: For durability.

      • Spandex: For elasticity.

  2. Fiber Preparation:

    • Washing, bleaching, and sterilizing the raw fibers to ensure purity.

    • Drying the fibers before further processing.

  3. Spinning:

    • Converting the prepared fibers into yarn.

    • Adjust yarn thickness and quality as per product specifications.

  4. Weaving/Knitting:

    • Weaving: For producing gauze or flat fabrics.

    • Knitting: For elastic bandages.

  5. Sterilization:

    • Apply sterilization processes like:

      • Ethylene Oxide (ETO).

      • Gamma Radiation.

      • Autoclaving.

  6. Cutting and Packaging:

    • Cut the fabric to required dimensions.

    • Ensure the cutting process is sterile.

    • Use surgical-grade sterile packaging.

  7. Quality Control:

    • Test tensile strength, elasticity, and microbial resistance.

    • Check absorbency levels for gauze bandages.

  8. Final Packaging and Distribution:

    • Seal the bandages in final medical-grade packaging.

    • Prepare for distribution to hospitals, pharmacies, or clinics.


Detailed Process Steps:

1. Raw Material Selection:

  • Natural fibers like cotton are highly absorbent, while synthetic fibers like polypropylene or polyester add durability and moisture resistance.

  • Elastic components like spandex or latex-free elastic ensure flexibility.

2. Fiber Preparation:

  • Raw cotton or synthetic fibers are cleaned and bleached to remove impurities.

  • Sterilization ensures that the fibers meet medical-grade cleanliness standards.

3. Spinning:

  • Prepared fibers are converted into yarn using spinning machines.

  • The thickness of the yarn is adjusted depending on whether the bandage is elastic or gauze-type.

4. Weaving/Knitting:

  • Weaving machines create gauze-like fabrics with open spaces for air permeability.

  • Knitting machines are used for elastic bandages, integrating spandex or similar materials.

5. Sterilization:

  • Sterilize the fabric to remove microbial contamination using:

    • Ethylene Oxide (ETO): Effective for medical-grade textiles.

    • Gamma Radiation: Common for medical equipment and textiles.

    • Autoclaving: Steam sterilization under pressure.

6. Cutting and Packaging:

  • Fabric is cut into standardized sizes using automatic or manual cutting machines.

  • Packaging occurs in a sterile environment to ensure no contamination.

7. Quality Control:

  • Conduct tests such as:

    • Tensile strength tests to ensure durability.

    • Absorbency tests for gauze bandages.

    • Elasticity tests for stretchable bandages.

  • Verify compliance with ISO 13485 and EN 13795 standards.

8. Final Packaging and Distribution:

  • Use vacuum-sealed or sterile pouches for each bandage.

  • Labels should include sterilization date, product type, and usage instructions.
