Embodiment 1

[0033] Such as Figure 1 to Figure 5 As shown, this embodiment provides a breath sampling device with virus purification effect, which is used in conjunction with a collection structure, and the collection structure is used to absorb substances in the user's exhaled air. The collected material can be an aerosol containing the new coronavirus. In this embodiment, the collection structure is a filter element. The filter element is molecular sieve and silica gel active physical adsorption desiccant. The adsorption of the filter element to the aerosol is physical adsorption. The filter element is conical and detachably embedded in a disposable medical-grade plastic mask. The mask conforms to the design of the human face to ensure the fit between the mask and the human body, thereby preventing the exhaled gas from the human body from escaping through the contact between the mask and the human body and polluting the air.

Embodiment 2

[0062] This embodiment provides an equivalent detection method to test the germ-disinfecting effect of the breath sampling device with virus purification effect in Embodiment 1. Please refer to Embodiment 1 for the structure of the breath sampling device with virus purification effect.

[0063] The equivalent detection method includes the following steps:

[0064] Step 1: Put the vinegar close to the sampling port 101, and detect the sour taste at the exhaust port 102;

[0065] Step 2: After the sour smell can be smelled at the exhaust port 102 , the disinfection structure 30 performs high-temperature disinfection on the air guide pipe 10 , and then detects the sour smell at the exhaust port 102 .

Abstract

The invention is applicable to the field of breath sampling devices with a virus purification effect, and provides a breath sampling device with a virus purification effect and an equivalent detectionmethod. The breath sampling device with the virus purification effect is used in conjunction with a collection structure, and comprises an gas-guide pipe, an airflow structure and a disinfection structure, wherein the gas-guide pipe is provided with a sampling port and an exhaust port, the sampling port is used to receive the breath of a user, the gas-guide pipe can contain the collection structure, and the collection structure is arranged between the sampling port and the exhaust port; the airflow structure is used to generate an airflow from the sampling port to the exhaust port in the gas-guide pipe; and the disinfection structure is arranged in the gas-guide pipe and positioned between the collection structure and the exhaust port, and is used for sterilizing and disinfecting the gasflowing through. The breath sampling device with the virus purification function provided by the invention can reduce the risk of infection of a collected person.

Description

technical field [0001] The invention belongs to the technical field of breath sampling devices, in particular to a breath sampling device with virus purification effect and an equivalent detection method. Background technique [0002] Pharyngeal swab sampling and detection is one of the important links in the fight against new coronary pneumonia, and it is also the key technical support for the diagnosis or exclusion of close contacts and suspected patients. The pharynx includes nasopharynx, oropharynx, and hypopharynx. Sampling through the nose is a nasopharyngeal swab, and sampling through the mouth is an oropharyngeal swab. No matter nasopharyngeal swab or oropharyngeal swab is used, because the collector and the collected person are in a face-to-face position, and the collected person is easy to sneeze during the operation, and a movement of opening the mouth or coughing may cause Generates aerosols that carry the virus and are therefore more dangerous to the collectors...
