Cotton balls usually refer to disposable spherical or quasi-spherical products made from pure cotton fibers that meet national or industry standards through specific processing techniques. Its core characteristics are based on materials and structure:
Material: The main raw material is medical absorbent cotton. Degreasing treatment removes the natural lipids in cotton, endowing it with excellent hydrophilicity and liquid absorption. It can quickly absorb and lock in chemical solutions (such as iodophor, alcohol, and physiological saline), while the fibers are less likely to fall off, ensuring the cleanliness of the application area.
Structure: Through uniform pressing by professional machinery, a spherical structure with multiple pores inside and a dense exterior is formed. This structure optimizes its liquid carrying capacity and controllable release ability, ensuring that it can be fully moistened during use and evenly seep out when squeezed, avoiding dripping and spillage.
Production process
Standardized production is the cornerstone for the safety and effectiveness of cotton balls. Its standardized process mainly includes:
Raw material selection and degreasing: High-quality long-staple cotton is selected and degreased and bleached through processes such as steaming and rinsing to meet medical standards.
Carding and shaping: After carding, the fibers are quantitatively grasped and pressed into shape by automated equipment to ensure that the weight and density are consistent.
Sterilization and packaging
Disinfection grade/medical grade cotton balls: They must undergo sterilization procedures that have been verified as qualified, such as ethylene oxide sterilization or irradiation sterilization. The packaging must use medical dialysis paper and remain sterile within the validity period. The packaging should have clear labels of "sterilized" and "sterile" along with the sterilization validity period.
Non-disinfection grade/general grade cotton balls: Only undergo cleaning treatment, with no sealing or sterility requirements for packaging, marked as "General" or "for cleaning use".
Professional application scenarios
According to its classification, the application scenarios are strictly distinguished:
A. Medical-grade cotton balls (sterilized) - Invasive and high-risk operations
Skin disinfection before surgery and puncture: For critical areas such as central venous catheterization and surgical incisions, standardized disinfection with iodophor or chlorhexidine alcohol is carried out.
Wound care: Clean open wounds and remove exudate and contaminants.
Disinfection of injection and blood collection sites: Follow the principle of aseptic operation to prevent pathogen invasion.
Temporary cleaning and disinfection of medical devices: such as wiping the ear parts of stethoscopes, thermometers, etc.
B. Standard grade cotton balls - Non-invasive and low-risk care
Personal hygiene care: Use skin care products in combination for local skin care.
Cosmetic removal: Especially suitable for removing stubborn makeup from the eyes and lips.
Surface cleaning of items: Wipe optical lenses, precision instruments and meters, etc. The texture is soft and free of wear.
Clinical and household usage norms
To ensure safety and effectiveness, the following norms must be adhered to:
Strictly distinguish and do not mix.
It is strictly prohibited to use non-sterilized ordinary cotton balls in any situation where the skin barrier is damaged (such as wounds, ulcers, acne breaks).
Sterilized cotton balls in individual small packages should always be kept in the family medicine cabinet and placed separately from the cotton balls used for daily makeup, with clear labels.
Aseptic operation principles (for medical cotton balls) :
Check the integrity and validity period of the packaging before opening it.
After opening the package, use sterile tweezers to take it out and avoid direct contact with your hands.
Follow the "use one, discard one" principle. It is strictly prohibited to repeatedly dip the same cotton ball in the disinfectant or cross-wipe different parts of the body.
Environment and Disposal
After use, cotton balls should be treated as medical waste or domestic garbage and sorted for disposal. Medical cotton balls contaminated with blood or body fluids should be placed in special yellow infectious waste garbage bags in accordance with the "Regulations on the Administration of Medical Waste".
