Description

Technical Field

[0001] This utility model relates to the field of pathogen sampler technology, specifically to a sampler for respiratory tract infection pathogens. Background Technology

[0002] The respiratory tract is part of the respiratory system, responsible for transporting air to the lungs for gas exchange. It includes organs such as the nasal cavity, pharynx, larynx, trachea, and bronchi. The nasal cavity and pharynx are the beginning of the respiratory tract, the larynx is the narrowest part, and the trachea and bronchi are the main body. At the ends of the trachea and bronchi are numerous alveoli, used for gas exchange. Respiratory tract infection refers to inflammatory diseases caused by pathogens invading the respiratory tract, including upper and lower respiratory tract infections. Upper respiratory tract infections include colds, pharyngitis, laryngitis, and tonsillitis; lower respiratory tract infections include bronchitis and pneumonia. Symptoms of respiratory tract infections include fever, cough, sputum production, nasal congestion, runny nose, sore throat, hoarseness, headache, and muscle aches.

[0003] The principle of existing respiratory pathogen samplers is generally to collect respiratory secretions through sampling swabs and store the collected respiratory secretions in sampling tubes. The sampling frame fixes the sampling tubes and uses protective equipment such as masks, gloves, and goggles to ensure the safety of medical personnel. These structures together constitute a complete respiratory pathogen sampler for collecting and analyzing pathogens in respiratory secretions.

[0004] When using respiratory pathogen samplers for large-scale outdoor sampling, a large number of sampling supplies, such as sampling swabs, sampling tubes, and preservation solutions, need to be prepared before sampling. During the sampling process, each subject needs to be sampled individually, which takes a considerable amount of time. In addition, if there are many subjects, the sampling personnel may become fatigued, thus affecting the sampling efficiency. After sampling, the sampling swabs and sampling tubes need to be disinfected and preserved. After sampling, the collected data needs to be entered and statistically analyzed, which makes the entire sampling process take a long time. When sampling respiratory pathogens in high-temperature environments, the activity of some pathogens may decrease or they may die, resulting in a reduction in the number of pathogens sampled, thus affecting the accuracy of the test results. The reduced activity or death of pathogens reduces the sampling effect of the respiratory pathogen sampler. Utility Model Content

[0032] Please refer to the accompanying drawings as one embodiment of the present invention. Figures 2-4 As shown, the bottom end of the sampling tube 5 is passed through the through hole 15, and the bent part of the elastic sealing block 14 is bent. The placement hole 7, which is not into which the sampling tube 5 is inserted, is sealed and blocked by the close connection between several sets of elastic sealing blocks 14, thereby preventing the cold air in the cooling chamber 12 from escaping and thus extending the heat preservation time of the sampling box 1.

[0033] In this embodiment, the elastic sealing block 14 has a fan-shaped cross-section and is composed of a fixed part and a bent part.

[0034] In this embodiment, the inner wall of the box 2 is detachably equipped with a support base 18.

Both sides of the outer surface of the limiting member 19 are symmetrically provided with a locking block 20 that engages with the support base 18. The limiting member 19 and the locking block 20 can improve the stability of the connection between the placement seat 4 and the support base 18. The support base 18 is provided with a through groove that communicates with the cooling chamber 12. The upper end of the placement seat 4 is symmetrically provided with two sets of handles 21. The support base 18 is provided with several sets of limiting grooves that connect with the limiting member 19. The limiting grooves are symmetrically provided with locking slots that engage with the locking block 20. The handles 21 facilitate the disassembly and separation of the placement seat 4 and the support base 18, thereby facilitating the replacement or placement of the cooling bag 9 inside the cooling box 8.

[0035] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 2 and Figure 5 As shown, move the handle 21 to move the placement seat 4. The placement seat 4 moves upward to move the limiting member 19. Moving the limiting member 19 moves the locking block 20. The locking block 20 is removed from the locking groove, and the limiting member 19 is removed from the limiting groove. Thus, the placement seat 4 and the support seat 18 are disassembled and separated. The cooling bag 9 inside the cooling box 8 is taken out from the through groove and the cooling bag 9 is replaced.

[0036] After the cooling bag 9 is replaced, align the placement seat 4 with the housing 2, so that the placement seat 4 moves downward and the limiting member 19 is inserted into the limiting groove, and the locking block 20 is locked into the locking groove, thereby fixing the placement seat 4 to the support seat 18.

[0037] In this embodiment, the bottom end of the elastic support member 11 is vertically provided with a mounting ring 22, and the upper end surface of the placement seat 4 is provided with a number of mounting grooves connected to the mounting ring 22. The mounting grooves are located on the outside of the mounting grooves, and the mounting ring 22 is threadedly fixed to the mounting grooves.

[0038] Please refer to the accompanying drawings as one embodiment of the present invention. Figure 2 and Figure 3 As shown, rotating the elastic support 11 causes the mounting ring 22 to rotate, fixing the mounting ring 22 into the mounting groove, thereby enabling the elastic support 11 to be disassembled or fixed.

[0039] In this embodiment, the sampling box 1 is set as an insulated box. Locking devices 23 are symmetrically installed on the box body 2 and the box cover 3. A sealing gasket 24 that fits against the box body 2 is provided on the inner side of the box cover 3. The sealing gasket 24 can improve the sealing performance between the box body 2 and the box cover 3.

[0040] In one embodiment of the present invention, the lid 3 is rotated so that the lid 3 is fitted and connected to the body 2, the sealing gasket 24 is fitted and connected to the body 2, and the locking member 23 fixes the body 2 and the lid 3 together, thereby sealing the connection between the body 2 and the lid 3.

[0041] The working principle of this utility model is as follows: When sampling respiratory pathogens, the box cover 3 is opened, and a sampling swab 6 is used to collect respiratory secretions. The collected sampling swab 6 is then placed into the sampling tube 5, and the sampling tube 5 is sealed and fixed in the placement seat 4. The bottom of the sampling tube 5 is passed through the placement hole 7, and the bent part of the elastic sealing block 14 is bent. The placement hole 7, where the sampling tube 5 is not placed, is sealed and blocked by the close connection between several sets of elastic sealing blocks 14, thus preventing the loss of cold air in the cooling chamber 12 and extending the heat preservation time of the sampling box 1. The bottom of the sampling tube 5 is placed into the cooling chamber 12, and the cooling bag 9 in the cooling box 8 can cool the cooling chamber 12, thereby cooling the head of the sampling tube 5. This can effectively maintain the activity of pathogens during the sampling process and improve the accuracy of detection.

[0042] Move the handle 21 to move the placement seat 4. The placement seat 4 moves upward, causing the limiting member 19 to move. Moving the limiting member 19 causes the locking block 20 to move. Remove the locking block 20 from the locking groove and remove the limiting member 19 from the limiting groove. This separates the placement seat 4 from the support seat 18. Take the cooling bag 9 from the through groove inside the cooling box 8 and replace the cooling bag 9. After replacing the cooling bag 9, align the placement seat 4 with the box 2, so that the placement seat 4 moves downward and inserts the limiting member 19 into the limiting groove. Lock the locking block 20 into the locking groove, thereby fixing the placement seat 4 to the support seat 18.

[0043] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
