How exactly do nasopharyngeal swabs and oropharyngeal swabs operate?

 

Our respiratory tract is divided into the upper respiratory tract and the lower respiratory tract. The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract includes the trachea, bronchi, and lungs. It is medically distinguished by the cricoid cartilage as the boundary.

 

Nasopharyngeal swab collection method

 

During nasal swab collection.

 

1. Ask the patient to keep his head still and remove the secretions from the middle surface of the anterior nasal aperture. The collector can stand to the side of the collected person to reduce occupational exposure due to coughing and sneezing and to relieve the collector's stress.

 

2、Measure the distance from the nostril to the root of the ear with a swab and mark it with your hand.

 

3、Gently insert the swab through the nasal cavity in a vertical nose (face) direction into the nostril with a wall-touching sensation until the finger touches the nose, allowing the swab to remain in the nose for 15-30 seconds, and then gently rotate it 3 times.

 

4、Put the swab into the virus delivery medium and break the swab rod so that it is completely placed in the tube.

 

5、Screw the tube cover, mark it well and put it into a plastic bag and seal it well.

 

 

6、Send the specimen for examination in time
