2025-04-15 09:15:21
In the medical field, water absorbent resin (SAP) small packaging is widely used in wound care, hygiene products, and medical materials due to its high water absorption, hygiene and safety, and convenient use.
The following are specific application scenarios and packaging characteristics:
1、 Main applications in the medical field
1. Wound dressings and hemostatic materials
• Purpose: Used for absorbing exudate from surgical wounds, burns, ulcers, and other wounds, and maintaining a moist environment for the wound.
As a hemostatic powder (such as first aid for trauma), it can quickly absorb blood to form gel and compress to stop bleeding.
Packaging requirements: Aseptic independent packaging (such as 1g/5g aluminum foil bags), ethylene oxide or irradiation sterilization.
2. Medical sanitary pads/nursing pads
• Usage: Operating table pad, anti pressure ulcer pad for bedridden patients, absorbs body fluids to prevent skin immersion.
• Packaging features: Prefabricated in sheet or roll form, small packaging (such as 10 sheets/box) is convenient for single use.
3. Disposable medical ice packs
• Usage: SAP can be used as a cold compress ice pack after absorbing water (such as joint sprains, postoperative swelling reduction).
• Packaging design: Double layered sealed bag (inner bag with dry SAP, outer bag with water), mixed and activated during use.
4. Pocket making/incontinence care products
• Usage: Absorb urine or excrement, reduce skin irritation.
• Packaging form: Made into small bags (such as 20cm × 30cm) by compounding with non-woven fabric, containing antibacterial coating.
2、 Special requirements for medical grade SAP small packaging
1. Health and safety standards
Aseptic processing: It must comply with the ISO 13485 medical device quality management system.
• Biocompatibility: Tested for cytotoxicity and skin irritation (such as ISO 10993).
2. Packaging material
• Inner layer: Medical grade aluminum foil or Tyvek material, anti-bacterial and breathable.
• Outer layer: medical PE/PP plastic, printed with sterilization label and expiration date.
3. Label information
• Must indicate: product name (such as "medical high water absorbent resin"), registration certificate number, production batch number, sterilization method.
Contraindications (such as' not suitable for open wounds').
3、 Precautions for use
1. Use immediately after opening: Avoid exposure to air pollution.
2. Prohibition of repeated sterilization: Some SAPs may degrade and become ineffective when exposed to high temperatures.
3. Waste disposal: SAP gel after aspirating shall be classified and disposed as medical waste.
4、 Innovative application direction
Antibacterial SAP: Adding silver ions or chitosan to reduce the risk of infection.
Degradable SAP: used for environmentally friendly medical dressings (such as polylactic acid based resins).
SAP small packaging in the medical field needs to balance functionality, safety, and convenience, strictly following medical device regulations (such as China's "Classification Catalogue of Medical Devices" or FDA certification).
