The following is the correct usage method of the iClean® nylon sampling swab:

Nasal Cavity Sampling

1. Preparation Work
   Wash your hands thoroughly, put on disposable gloves and a mask. Take out the iClean® nylon sampling swab. Be careful not to touch the swab head to keep it in a sterile state.
2. Sampling Posture
   Ask the person being sampled to tilt their head slightly backward. The sampler holds the swab and gently inserts the swab into one of the nasal cavities. The insertion depth is generally about 2.5 to 3 centimeters for adults and about 1.5 to 2 centimeters for children. It can be adjusted according to the actual situation.
3. Collecting the Sample
   Keep the swab in the nasal cavity for a few seconds, and gently rotate it 3 to 5 times to fully collect the secretions and cells on the surface of the nasal mucosa. Then, slowly remove the swab.
4. Preserving the Sample
   Immediately put the sampled swab into the supporting sample preservation solution or collection tube, and seal it according to the specified method to avoid sample leakage and contamination.

Oral Cavity Sampling

1. Preparation and Cleaning
   First, clean your hands and take protective measures. The person being sampled rinses their mouth with clean water first to remove food residues and other impurities in the mouth. Then, take out the swab.
2. Sampling Operation
   Ask the person being sampled to open their mouth wide. Insert the swab into the oral cavity and gently wipe or scrape on the buccal mucosa on both sides, the gums, or the surface of the tongue. When wiping, ensure that the swab is in full contact with the mucosa or tissue. You can repeat the wiping 5 to 10 times to obtain an adequate sample of cells.
3. Sample Processing
   After sampling is completed, quickly put the swab into the corresponding preservation container, seal it well, and make a mark.

Throat Sampling

1. Preparatory Work
   Prepare the iClean® nylon sampling swab. Ask the person being sampled to sit in a comfortable position and tilt their head slightly backward to fully expose the throat.
2. Sampling
   The sampler gently presses the tongue of the person being sampled with a tongue depressor, and gently inserts the swab into the throat. Wipe or scrape the sample on the tonsils, the posterior pharyngeal wall, and other parts. Note that the movement should be gentle and rapid to avoid causing discomfort such as nausea and vomiting in the person being sampled.
3. Subsequent Processing
   After sampling is completed, put the swab into the preservation solution or collection tube as soon as possible, seal it, and send it for inspection.

Wound Sampling

1. Disinfection
   First, clean the skin around the wound with normal saline or an appropriate disinfectant to remove dirt and secretions and reduce the contamination of miscellaneous bacteria.
2. Sampling
   Select a suitable length and model of the iClean® nylon sampling swab according to the size and depth of the wound. Gently insert the swab into the wound, and wipe or dip the sample at the edge of the wound or the base where there are secretions or suspected infections. Be careful to avoid the swab coming into contact with the normal skin around the wound.
3. Preservation and Submission for Inspection
   After taking out the swab, immediately put it into a sterile sample preservation tube, seal it well, and send it to the laboratory for testing as soon as possible.

No matter which part is sampled, the used iClean® nylon sampling swab should be properly disposed of in accordance with the relevant medical waste disposal regulations to prevent cross-infection and environmental pollution.
