Description

Technical Field

[0001] This application relates to the field of respiratory testing, and in particular to specimen sampling devices for respiratory testing. Background Technology

[0002] The respiratory tract is the passageway through which airflow passes during respiration. It is divided into upper and lower parts: the nose, pharynx, and larynx together form the upper respiratory tract. The trachea, bronchi, and lungs together form the lower respiratory tract, or tracheal tree. The tracheal tree has become increasingly complex with animal evolution.

[0003] Current respiratory tract testing methods typically involve connecting the patient's breath to an external instrument for testing. However, this often involves frequently moving the instrument or the patient to a designated location, which is inconvenient. Furthermore, it is also difficult to move patients who have difficulty moving around. Therefore, a specimen sampling device for respiratory tract testing is needed to solve these problems. Utility Model Content

[0004] To address the inconvenience of frequently moving instruments for testing or having patients travel to designated locations for testing, this application provides a specimen sampling device for respiratory tract testing.

[0006] By adopting the above technical solution, the collecting cotton board is limited to the air outlet of the exhaust fan by the guide rail. The exhaust fan blows the gas inside the collection box into the collecting cotton board. The collecting cotton board collects moisture, bacteria and other substances in the breather's exhaled air. The collecting box is used to place the collected cotton board after collection.

[0007] Preferably, the one-way ventilation mechanism includes a connecting ring located at the end of the air duct near the mask, and a blocking plate is provided at the bottom of the connecting ring, with one end of the blocking plate hinged to the bottom of the connecting ring.

[0008] By adopting the above technical solution, after the tester puts on the mask, the airflow will blow the air-blocking plate downwards when the tester exhales, guiding the exhaled gas into the collection box. When the tester inhales, the air-blocking plate will block the air delivery tube to prevent the gas in the collection box from being sucked out.

[0009] Preferably, a heating rod is fixed through one bottom side of the outer casing, and multiple heating rods are provided, which are arranged horizontally at equal intervals.

[0010] By adopting the above technical solution, multiple heating rods are energized to maintain the internal temperature of the outer shell close to that of the human body, and to keep the temperature of the collected cotton board at a suitable level for the human body.

[0011] Preferably, an alcohol box is fixed to one side of the top of the outer shell, the top of the outer wall of the alcohol box is snapped to both ends of the mask, a liquid extraction tube is fixed through the middle of the top of the alcohol box, an atomizer is provided at the top of the liquid extraction tube, and a liquid inlet is opened through the top of one side of the alcohol box.

[0012] By adopting the above technical solution, alcohol is injected into the alcohol box from the inlet tank. After the test is completed, the mask is snapped into the alcohol box. Then, the exhaust fan and nebulizer are turned on. The nebulizer atomizes the alcohol inside the alcohol box and then enters the air duct and collection box through the mask for comprehensive disinfection.

[0013] Preferably, the length of the inner wall of the collection box is adapted to the length of the collection cotton board, and multiple placement slots are provided on both sides of the outer shell.

[0014] By adopting the above technical solution, a collection box is used to place the collected cotton boards after collection, and a large number of collected cotton boards can be placed separately inside the outer shell.

[0015] Preferably, a connecting plate is fixed to one end of the collection box, and an information card is fixed to the top of one side of the connecting plate. The connecting plate is interlocked with the outer wall of the outer shell.

[0016] By adopting the above technical solution, the collection box is fixed in the placement slot by snapping the connecting plate with the outer shell, and the collected cotton swabs are labeled by filling in the corresponding patient information through the information card.

[0017] Preferably, a through hole is provided on one side of the mask, and the through hole is sealed to the air duct. Grooves are provided on both sides of the middle of the top and bottom of the mask, and a strap is fixed to the middle of one side of the mask.

[0018] By adopting the above technical solution, the mask is worn with straps during testing, and the groove is designed to accommodate the nose and allow for the intake of external air.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application uses a strap to put on a mask. The tester breathes normally and then removes the mask after a period of time. At this time, a large amount of exhaled air is collected in the collection box. The exhaust fan blows the air inside the collection box into the collection cotton plate. The collected collection cotton plate is placed in the collection box. By energizing multiple heating rods, the temperature inside the outer shell is kept close to that of the human body, thereby collecting the air breathed by the patient and maintaining the activity of the collected sample. This makes the sample more convenient to use for testing.

[0021] 2. This application achieves rapid disinfection for subsequent use by snapping a mask into an alcohol container, then turning on the exhaust fan and nebulizer. The nebulizer atomizes the alcohol inside the container, which then passes through the mask into the air duct and collection box for thorough disinfection. After the nebulizer is turned off, the exhaust fan continues to work for five minutes before stopping to remove the alcohol from the device. Attached Figure Description

The exhaust fan 7 has guide rails 9 fixed at both ends on the side away from the gas collection box 10. The collection cotton plate 8 is movably connected inside the two guide rails 9. The collection cotton plate 8 is limited to the air outlet of the exhaust fan 7 by the guide rails 9. The exhaust fan 7 blows the gas inside the collection box 10 into the collection cotton plate 8. The collection cotton plate 8 collects the moisture, bacteria and other substances in the breather's exhaled air. The outer shell 1 is provided with a collection box 6, which is used to place the collected cotton plate 8 after collection.

[0031] Reference Appendix Figure 4 The one-way ventilation mechanism includes a connecting ring 111, which is located at the end of the air duct 11 near the mask 12. A blocking plate 112 is provided at the bottom of the connecting ring 111, and one end of the blocking plate 112 is hinged to the bottom of the connecting ring 111. After the tester puts on the mask 12, when exhaling, the airflow will blow the blocking plate 112 downward, guiding the exhaled gas into the collection box 10. When inhaling, the blocking plate 112 will block the air duct 11 to prevent the gas in the collection box 10 from being sucked out.

[0032] Reference Appendix Figure 1 The outer shell 1 has a heating rod 2 fixed through one side bottom. Multiple heating rods 2 are arranged horizontally and equidistantly. By energizing the multiple heating rods 2, the temperature inside the outer shell 1 is kept close to that of the human body, and the temperature of the collected cotton plate 8 after collection is kept suitable for the human body.

[0033] Reference Appendix Figure 6 The outer shell 1 has an alcohol box 13 fixed to one side of its top. The top of the outer wall of the alcohol box 13 is snapped into both ends of the mask 12. A liquid extraction tube 131 is fixed through the middle of the top of the alcohol box 13. An atomizer 132 is installed at the top of the liquid extraction tube 131. An inlet 133 is opened through the top of the alcohol box 13. Alcohol is injected into the alcohol box 13 through the inlet 133. After the test is completed, the mask 12 is snapped into the alcohol box 13. Then the exhaust fan 7 and the atomizer 132 are turned on. The atomizer 132 atomizes the alcohol inside the alcohol box 13 and then enters the air duct 11 and the collection box 10 through the mask 12 for comprehensive disinfection.

[0034] Reference Appendix Figure 2 and 3The length of the inner wall of the collection box 6 is matched with the length of the collection cotton board 8. The outer shell 1 has a placement slot 3 on both sides. Multiple placement slots 3 are provided. The collection box 6 is used to place the collected cotton board 8. A large number of collection cotton boards 8 can be placed inside the outer shell 1.

[0035] Reference Appendix Figure 1 and 3 The collection box 6 has a connecting plate 4 fixed at one end, and an information card 5 fixed at the top of one side of the connecting plate 4. The connecting plate 4 is interlocked with the outer wall of the outer shell 1. The collection box 6 is fixed in the placement slot 3 by the interlocking of the connecting plate 4 with the outer shell 1. The corresponding patient information is filled in through the information card 5, and the collected cotton swabs 8 are labeled.

[0036] Reference Appendix Figure 5 The mask 12 has a through hole 121 on one side, which is sealed to the air duct 11. The top and bottom of the mask 12 have grooves 122 on both sides. A strap 123 is fixed in the middle of one side of the mask 12. The mask 12 is worn with the strap 123 during testing. The groove 122 is used to place the nose and draw in external air.

[0037] The implementation principle of the specimen sampling device for respiratory tract testing in this application embodiment is as follows: First, the entire device is disinfected. The mask 12 is then snapped into place with the alcohol container 13. Next, the exhaust fan 7 and nebulizer 132 are activated. The nebulizer 132 atomizes the alcohol inside the alcohol container 13, which then passes through the mask 12 into the air duct 11 and collection box 10 for thorough disinfection. After the nebulizer 132 is turned off, the exhaust fan 7 continues to operate for five minutes before stopping to remove alcohol from the device. The mask 12 is then removed, and a clean collection cotton plate 8 is placed on the guide rail 9. The mask 12 is then worn using the strap 123. The groove 122 is designed to accommodate the nose and allow for the intake of external air. When the person exhales normally, the airflow pushes the air-blocking plate 112 downwards, guiding the exhaled air into the collection box. In the collection box 10, the air-blocking plate 112 blocks the air duct 11 during inhalation to prevent the gas in the collection box 10 from being sucked out. After breathing for a period of time, the mask 12 is removed. At this time, a large amount of exhaled gas is collected in the collection box 10. The exhaust fan 7 is turned on to work. The exhaust fan 7 blows the gas inside the collection box 10 into the collection cotton plate 8. The collection cotton plate 8 collects moisture, bacteria and other substances in the breather's exhaled gas. Then the collected collection cotton plate 8 is placed in the collection box 6. The collection box 6 is fixed in the placement slot 3 by the connecting plate 4 and the outer shell 1. The corresponding patient information is filled in through the information card 5, and the collected collection cotton plate 8 is labeled. By energizing multiple electric heating rods 2, the temperature inside the outer shell 1 is kept close to that of the human body, so that the temperature of the collected collection cotton plate 8 is suitable for the human body.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
