Description

Mask for sampling pathogen of coronavirus pneumonia

Technical Field

The utility model relates to a respiratory tract pathogen detects the field, concretely relates to a gauze mask that is used for novel coronavirus pneumonia pathogen to sample.

Background

The novel coronavirus pneumonia is an infectious disease caused by infection of novel coronavirus SARS-CoV2 in China. The important point of the existing epidemic prevention and control lies in that virus infectors, especially mild and asymptomatic patients, need to be isolated in time. The method for diagnosing the disease mainly detects virus nucleic acid in samples such as nasopharyngeal swab, sputum, alveolar lavage fluid and the like.

However, the sensitivity of the existing nasopharyngeal swab for detecting pathogen nucleic acid is only 30% -50%, the detection results of a large number of patients are false negative, even the nasopharyngeal swabs of the patients are negative for many times, and finally the detection result of the nasopharyngeal swabs of the patients is positive through the alveolar lavage fluid detection. And when the nasopharyngeal swab is used for sampling, the nasopharyngeal swab is easy to splash and is relatively dangerous.

The lower respiratory tract of viral pneumonia has higher viral load than the upper respiratory tract, so the positive rate of alveolar lavage fluid is higher than that of nasopharyngeal swab, but the sampling process is complex, the technical requirement is high, the time is long, the splashing is easy, the risk is high, and the pulmonary alveolar lavage fluid cannot be developed on a large scale.

Nasopharyngeal swab sampling is convenient and easy, and is still the main sampling method, but the detection sensitivity is too low. A large number of patients with SARS-CoV2 infection are highly suspected, but negative nasopharyngeal swab detection, and how to diagnose them, becomes an urgent priority for prevention and control of new coronavirus pneumonia.

All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

Referring to fig. 1 and 2, the mask for sampling a novel coronavirus pneumonia pathogen provided by the embodiment of the present application includes a mask body 1 and wearing parts 3 disposed on both sides of the mask body 1 and wearable by a user. When the mask is used, the mask is worn on the face of a user through the wearing part 3, and meanwhile, the mask body 1 covers the mouth and the nose of the user and is used for blocking pathogens. The mask body 1 and the wearing part 3 can be integrated by sewing, ultrasonic fusion or thermal fusion, etc., so as to increase the strength of the mask. Mask body 1 is equipped with the annex 5 that is arranged in adsorbing the pathogen in the person's mouth nose expired gas towards the facial one side of wearer, and annex 5 can dismantle the setting with mask body 1, is convenient for take out annex 5 for the diagnosis of disease. Preferably, the attachment 5 allows the air to pass through without affecting the breathability of the mask and the comfort of the wearer.

The utility model provides a gauze mask is worn the back for a long time through the user, and annex 5 can absorb the pathogen in a large amount of breathing gas, and when the user was suspected infection case, can take out annex 5 in the gauze mask that the user wore for a long time, put into and be ready-test in the sampling pipe that is equipped with the preservative fluid for pathogen detection, when the wearer was infection case, adsorbed the pathogen in the annex 5, when the wearer was non-infection case, no pathogen in the annex 5.

Specifically, when a wearer has symptoms such as fever and cough and is suspected to be infected with a disease, the medical staff can take out the accessory 5 in the mask body 1 worn by the wearer and seal and store the accessory for inspection, and the medical staff can assist diagnosis by detecting whether the accessory 5 contains pathogens or not.

Can assist disease diagnosis through set up annex 5 on gauze mask body 1, the sampling is easy, and it is convenient simple to preserve to can reduce the risk that medical staff faces and is infected by patient's splash in the sampling process.

The position of the attachment 5 corresponds to the position of the nose and mouth of the wearer, facilitating the attachment of breathing gases, spray and pathogens to the attachment 5. And the accessory 5 is made of melt-blown non-woven fabric, and the melt-blown non-woven fabric has better adsorbability and filterability, so that the attachment of pathogens is facilitated, and the accuracy of a detection result is improved.

In some embodiments, the mask body 1 is further provided with a pocket 4 for holding the accessory 5 on the side facing the wearer's face, and the pocket 4 is provided with an opening on the side thereof, which is sized to allow the accessory 5 to pass through.
