Description
Technical Field
The invention relates to medical protection articles, in particular to a throat swab collecting device for reducing the risk of novel coronavirus infection and a collecting method thereof.
Background
Infectious diseases are a group of diseases caused by a variety of pathogens that can be transmitted from person to person, from animal to animal, or from person to animal.
An infectious disease is an infectious disease that can be transmitted from one person or other species to another person or species via various routes. Typically, such diseases may be transmitted by direct contact with infected individuals, infected individuals' body fluids and excretions, contaminated objects by infected individuals, through air transmission, water transmission, food transmission, contact transmission, soil transmission, vertical transmission, and the like.
The new coronavirus outbreak (named as COVID-19) occurs in 2020, so that the infected people are more, and after the people are infected, the new coronavirus pneumonia can be infected, and isolation treatment is needed. Respiratory droplets and contact transmission are currently considered to be the primary transmission pathways for new coronaviruses.
The collection of the throat swab is divided into two types, namely the collection of the nasopharyngeal swab and the collection of the oropharyngeal swab, and is an important check for detecting the presence or absence of the novel coronavirus.
The traditional nasopharyngeal swab collection method is as follows:
1) Putting the swab into physiological saline for wetting;
2) Measuring the distance from the nostril to the auricle by using a swab and marking by using a finger;
3) Inserting the swab into nostril in vertical direction of nose (face) until finger touches nose, making the swab stay in nose for 15-30 seconds, and then lightly rotating for 3 times;
4) Putting the swab into a virus transport medium, and breaking off the swab rod to enable the swab rod to be completely placed in a tube;
5) And screwing the pipe cover, marking, and putting into a plastic bag to seal.
The traditional oropharyngeal swab interview method is as follows:
1) The patient is asked to rinse the mouth with normal saline;
2) The swab was placed in sterile saline (without penicillin to prevent patient allergy) and moistened (moistened swab was able to pick up more cells than dry swab). Inhibiting the swab from being placed in the virus transport medium to moisten the swab;
3) The inspector uses the tongue depressor to assist, the pharyngeal swab passes over the tongue root to reach the lesion of the isthmus, and the tongue and the oral mucosa are prevented from being contacted when the inspector takes out the tongue;
4) Putting the swab into a virus transport medium, and breaking off the swab rod to enable the swab rod to be completely placed in a tube;
5) And screwing the pipe cover, marking, and putting into a plastic bag to seal.
In collecting specimens, medical personnel use sterile swabs to pass through the mouth or nasal cavity of a patient. During this procedure, the patient opens his mouth, potentially exhaling a large amount of virus-carrying aerosols; some patients can sneeze and cough due to the discomfort of the nasopharynx or the oropharynx, splash spray, and each time sampling is carried out, the head of a sampling person needs to be close to the head of the patient, and the air exhaled by the patient is in close contact with medical staff, so that the risk of infection is extremely high for the medical staff collecting throat swab samples. Meanwhile, if the operation is not good, the position reached by the swab is insufficient, or the rotation angle of the swab is insufficient, the sampling result is affected.
Therefore, there is an urgent need to develop a product that covers the mouth and nose of a patient and can also have the collection function to solve the above-mentioned technical problems.
