Problems solved by technology

[0002] When respiratory diseases, such as new coronaviruses, etc., respiratory samples of entry-exit personnel need to be collected at border ports, the methods for collecting samples of respiratory diseases mainly include throat swab method, bronchoalveolar lavage method, and nasopharyngeal aspirate or sputum specimen method, these methods take a long time, easily cause the discomfort of the collection object and cause passive infection of the medical staff performing the collection operation; in addition, when influenza epidemics or biological emergencies occur, the number of infected people surges, due to Due to the limitations of entry and exit environmental conditions, customs health and quarantine personnel can only carry out disease screening by strengthening epidemiological history inquiries and clinical symptom monitoring. The effect of epidemic control is difficult to guarantee, and there is a certain degree of subjective blindness

Embodiment 1

[0017] see figure 1 , in Embodiment 1 of the present invention, a human exhaled gas sampling device based on liquid phase collection, which includes: a temporary storage box 5, liquid inlets 4 are opened on the left and right sides of the upper end of the temporary storage box 5, and the temporary storage box 5 The virus collection liquid (i.e. liquid adsorbent) is put into the inside through the liquid inlet 4; the lower left side of the temporary storage box 5 is provided with a discharge pipe, and the discharge pipe controls the discharge rate through the automatic sampling assembly 2; the end of the discharge pipe A gas sample collection bag 1 is installed on the part, and a confinement box is arranged on the outside of the gas sample collection bag 1; an air inlet port 6 is installed on the upper end of the temporary storage box 5, and the air inlet port 6 is connected to the enrichment component 8 through the air pipe 7, and the enriched The assembly assembly 8 is sequen...

Embodiment 2

[0021] see figure 2 , further, the enrichment assembly 8 includes an enrichment box 13, the interior of the enrichment box 13 is a cavity 17, the left and right sides of the cavity 17 are simultaneously connected to the trachea 7, the left trachea 7 and the right trachea 7 The enrichment tube 14 is connected between them, the enrichment tube 14 is made of metal material, the surface of the enrichment tube 14 is provided with a resistance wire 15, and a temperature probe 16 is installed inside the enrichment tube 14;

[0022] When the respiratory samples enter the cavity 17 through the trachea 7, since the diameter of the enrichment tube 14 inside the cavity 17 is smaller than the diameter of the trachea 7, the respiratory samples are enriched in the enrichment tube 14 in turn, and the enrichment is detected by the temperature probe 16 The temperature of the respiratory tract sample inside the tube 14, if the temperature is too low, energize the resistance wire 15 to heat and ...

Embodiment 3

[0028] see image 3 , further, the automatic sampling assembly 2 includes a valve 21, a movable rod 22 and a sleeve 26, the valve 21 is movably installed inside the discharge pipe, the upper end of the valve 21 is provided with a movable rod 22, and the upper end of the movable rod 22 is movably installed in the sleeve Inside the cylinder 26, the sleeve 26 is arranged outside the discharge pipe;

[0029] Specifically, the movable rod 22 is provided with a magnetic block on the part inside the sleeve 26, and the movable rod 22 is provided with a compression spring 23 on the part between the magnetic block and the inner wall of the sleeve 26; A conductive column 25 is provided, and a magnetic induction coil 24 is installed on the outside of the conductive column 25;

[0030] When it is necessary to open the discharge pipe to unload, turn on the power to the conductive column 25, and the conductive column 25 generates the same electromagnetic field as the magnetic block through ...

Abstract

The invention belongs to the field of respiratory tract sample collection equipment, and particularly relates to a human exhaled air sampling device based on liquid phase collection. The human exhaledair sampling device comprises a temporary storage box, wherein a discharging pipe is arranged at the lower end of the left side of the temporary storage box, and the discharging pipe controls the discharging rate through an automatic sample discharging assembly; a gas sample collecting bag is installed on the tail end part of the discharging pipe, and a limiting box is arranged on the outer sideof the gas sample collecting bag; and an air inlet port is formed in the upper end of the temporary storage box, the air inlet port communicates with an enrichment assembly through an air pipe, the enrichment assembly sequentially communicates with a gas flowmeter, a buffer tank and an air suction pump through air pipes, and a disposable air blowing cover is installed at the upper end of the air suction pump. According to the human exhaled air sampling device based on liquid phase collection, in the process of collecting respiratory tract samples of entry personnel, the entry personnel blow air through the disposable air blowing cover, the blown gas samples sequentially pass through the air suction pump, the buffer tank, the gas flowmeter and the enrichment assembly and are finally conveyed into the temporary storage box through the air pipes, viruses in the gas samples are adhered to virus collecting liquid, and the collection efficiency is high.
