Description

Technical Field

[0001] This utility model relates to the field of virus sampling technology, and in particular to a portable virus sampling device that is protected against aerosol contamination. Background Technology

[0002] Virus sampling refers to the process of collecting virus particles from environmental or biological samples (such as air, water, surface swabs, blood, saliva, etc.) for subsequent laboratory analysis, including virus identification, concentration measurement, and genetic material analysis. Effective virus sampling is crucial for monitoring and controlling the spread of infectious diseases.

[0003] Existing portable virus sampling devices typically consist of a sampling swab and a sampling tube. The swab is used to collect the virus, and after sampling, it is inserted into the sampling tube for preservation. However, since the sampling swab needs to be handled by staff to collect the virus, it is easy to cause contamination. In addition, the sampling process can easily generate virus-carrying aerosols. These aerosols can spread into the surrounding environment, which not only poses an infection risk to the sampling personnel, but may also cause the virus to spread in the area and cause cross-infection.

[0004] Therefore, a portable virus sampling device has been developed that allows staff to complete virus sampling without touching cotton swabs and can adsorb the generated aerosols to prevent aerosol spread. Utility Model Content

[0005] To overcome the shortcomings of existing portable virus sampling devices, which require staff to handle the swabs for virus sampling, easily causing contamination, and generating virus-carrying aerosols during sampling that can lead to the spread of infection, this invention provides a portable virus sampling device that allows staff to complete virus sampling without touching the swabs and can adsorb the generated aerosols, preventing aerosol spread.

[0006] The technical solution is as follows: A portable virus sampling device for preventing aerosol contamination includes a first connecting sleeve, a slide rod, a protective cover, a sampling component, a preservation component, and an adsorption component. The slide rod is slidably connected to the first connecting sleeve, and the protective cover is connected inside the first connecting sleeve. The slide rod is equipped with a sampling component capable of sampling viruses, the sampling component is equipped with a preservation component capable of preserving the sample, and the first connecting sleeve is equipped with an adsorption component capable of adsorbing aerosols.

[0007] As an improvement to the above solution, the sampling component includes an installation sleeve, a sliding sleeve, a first telescopic spring, a sliding sleeve, and a cotton swab. The installation sleeve is slidably connected to the lower side of the sliding rod, and the sliding sleeve is slidably connected to the protective cover. The installation sleeve and the sliding sleeve are slidably connected, and the first telescopic spring connects the installation sleeve and the sliding sleeve. The protective cover has a slanted groove, and the sliding sleeve is movably connected to the protective cover through the slanted groove. The sliding sleeve and the sliding sleeve engage with each other, and the cotton swab is held between the sliding sleeve and the installation sleeve.

[0008] As an improvement to the above solution, the storage component includes a push rod, a slider, a second telescopic spring, and a sampling tube. The push rod is connected to the lower left side of the mounting sleeve, and the slider is slidably connected to the push rod. The slider is slidably connected to the protective cover. The second telescopic spring is connected between the mounting sleeve and the slider. The sampling tube is threadedly connected to the lower part of the first connecting sleeve, and the protective cover is located inside the sampling tube.

[0009] As an improvement to the above solution, a push block is provided on the left side of the push rod.

[0010] As an improvement to the above solution, the sampling tube is made of transparent material.

[0011] As an improvement to the above solution, the adsorption assembly includes a second connecting sleeve, a negative pressure tube, and a screw sleeve. The second connecting sleeve is threadedly connected to the upper part of the first connecting sleeve, and a screw sleeve is threadedly connected to the second connecting sleeve. A negative pressure tube is connected to the screw sleeve, and a control valve is provided on the negative pressure tube. The negative pressure tube passes through the first connecting sleeve and the protective cover.

[0012] Beneficial effects: This utility model pushes the installation sleeve downward to allow the swab to extend out of the protective cover to sample the virus. After sampling, the swab is retrieved into the protective cover and then falls into the sampling tube. By opening the control valve, the negative pressure tube is connected to the vacuum pump to extract the aerosol generated around the swab. This achieves the effect of allowing staff to complete virus sampling without contacting the swab and adsorbing the generated aerosol, thus preventing the spread of aerosol.

The sliding rod 2 is provided with a sampling component, the sampling component is provided with a storage component, and the first connecting sleeve 1 is provided with an adsorption component.

[0022] like Figures 3-5 As shown, the sampling assembly includes an installation sleeve 4, a sliding sleeve 41, a first telescopic spring 5, a sliding sleeve 6, and a cotton swab 7. The installation sleeve 4 is slidably connected to the lower side of the sliding rod 2, and the sliding sleeve 41 is slidably connected to the protective cover 3. The installation sleeve 4 and the sliding sleeve 41 are slidably connected, and the first telescopic spring 5 is connected between the installation sleeve 4 and the sliding sleeve 41.
