The following are the applications of cleaning polyester swabs in the medical field:

  1. Wound cleaning:
    • They can gently wipe the skin around the wound to remove dirt, blood, and exudate from the wound surface. This provides doctors with a clear view for accurately assessing the wound condition and avoids secondary contamination of the wound. For example, before a surgical operation, doctors will use polyester swabs to clean the skin around the surgical site.
    • For some superficial wounds, such as abrasions and scratches, polyester swabs can be used to clean the wounds, helping to keep them clean and promoting wound healing.
  2. Cleaning of instruments and equipment:
    • Cleaning of medical electronic equipment: The surfaces and interfaces of many electronic devices in the medical field, such as electrocardiographs, monitors, and ultrasonic equipment, are prone to accumulate dust, stains, and bacteria. The low – fiber – shedding characteristic of cleaning polyester swabs makes them very suitable for cleaning these devices. They can effectively remove dust and stains on the equipment surface without leaving fiber residues during the cleaning process, which would affect the normal use and performance of the equipment.
    • Cleaning of optical instruments: The lenses and optical components of optical instruments used in ophthalmology, otorhinolaryngology, and other departments, such as slit – lamps and otoscopes, need to be kept highly clean to ensure the accuracy of examination results. The soft material of polyester swabs can safely wipe optical lenses to remove pollutants such as fingerprints, dust, and secretions without scratching the lenses.
  3. Sampling:
    • Oral sampling: They can be used to collect samples of cells, bacteria, viruses, etc. in the oral cavity for the diagnosis and research of oral diseases. For example, when examining oral mucosal lesions, doctors can use polyester swabs to sample the affected area and then send the samples to the laboratory for analysis.
    • Nasal sampling: They are used to collect secretions or cell samples in the nasal cavity, which can be used for diagnosing nasal diseases, such as rhinitis and sinusitis, and also for detecting respiratory viruses, such as influenza viruses and COVID – 19.
  4. Drug application and delivery: In some topical treatments, drugs need to be accurately applied to the affected area. Polyester swabs can be used as a tool for drug application to evenly apply ointments, liquids, and other drugs to the surface of the skin or mucosa, improving the absorption effect of the drugs. For example, when treating oral ulcers, an appropriate amount of drug can be dipped with a polyester swab and applied to the ulcer surface.
  5. Cleaning verification: In the pharmaceutical industry and the production process of medical devices, cleaning verification is an important part of ensuring product quality and safety. Cleaning polyester swabs can be used to collect samples from the surfaces of production equipment, workshop environments, etc. to detect the presence of residual pollutants such as drugs, bacteria, and viruses, thereby verifying whether the cleaning effect meets the standards.
