Problems solved by technology

However, due to the current characteristics of the new coronavirus, that is, patients often do not show symptoms such as cough and fever in the early stage of onset or after a period of treatment, and the virus content in the upper respiratory module is very small, so nasopharyngeal swabs are used as samples of virus Nucleic acid testing, the test results are likely to have false negative results
At present, the best samples are deep sputum or alveolar lavage fluid obtained by bronchoscopy, but due to the limitations of professionals and equipment, traditional deep body fluid collection is difficult to be widely used

Embodiment 1

[0030] The inducing module is used to induce a patient to sneeze. The inducing module is a physical stimulation sneeze device, the physical stimulation device includes an installation tube fixed on the cover body, the internal thread of the installation tube is equipped with a telescopic rod, and the end of the telescopic rod located in the cover body is provided with a velvet. In order to physically stimulate the patient's nose, the end of the telescopic rod located outside the cover is a handle, which is used to drive the telescopic rod to move axially and rotate. The number of the installation tube, telescopic rod, and fluff is one, and the fluff corresponds to between the two nostrils of the patient, and is used to physically stimulate the outside of the patient's nostrils; the two ends of the installation tube are sealed The two ends of the telescopic rod located in the installation tube are polished rods, which are sealed with the seal.

Embodiment 2

[0032] There are two installation tubes, telescopic rods and fluff. The two fluffs correspond to the two nostrils of the patient respectively, and are respectively used to extend into the nostrils of the patient for physical stimulation. Other features are the same as those in Embodiment 1 of the induction module.

Embodiment 3

[0034] The inducing module is used to induce a patient to sneeze. The inducing module is a chemical stimulation sneezing device, and the chemical stimulation device includes a container fixed on the cover, and the spice powder containing capsaicin is placed in the container, and the container is provided with two delivery tubes, two One end of the transmission tube communicates with the container, and the other end is respectively used to extend into the patient's nostrils to output the spice powder containing capsaicin. The end of the container outside the cover is provided with a trigger button. The triggering method can adopt various existing spray structures, and can also adopt an injection push structure and the like. The module is placed on the nostrils. When the user breathes, the air with a small amount of spice powder is inhaled into the nose. After the capsaicin stimulates the nasal mucosa, the user is triggered to sneeze.

Abstract

The invention discloses a respiratory secretion sampling mask and particularly relates to a respiratory secretion sampling mask suitable for sampling respiratory secretion of a novel coronavirus pneumonia patient. The respiratory secretion sampling mask comprises a mask body, an induction module and a collection module are arranged on the mask body, the induction module is used for inducing a patient to generate respiratory reflex, and the collection module is used for collecting secretion discharged by the respiratory reflex of the patient.

Description

technical field [0001] The invention relates to the technical field of virus detection, in particular to a respiratory secretion sampling mask. Background technique [0002] The novel coronavirus pneumonia has endangered the lives and health of people all over the world. Rapid and effective detection of 2019-nCoV is the basis for epidemic control and patient treatment. At present, the detection method for the new coronavirus mainly uses the detection of viral nucleic acid. Due to the limited number of test specimens and operability, the most commonly used sampling method is still to collect nasopharyngeal swabs from the subjects. However, due to the current characteristics of the new coronavirus, that is, patients often do not show symptoms such as cough and fever in the early stage of onset or after a period of treatment, and the virus content in the upper respiratory module is very small, so nasopharyngeal swabs are used as samples of virus Nucleic acid testing, the tes...
