Technical Field
[0001] This utility model relates to the field of medical equipment, and in particular to a sputum expectoration device for tuberculosis care. Background Technology
[0002] Tuberculosis is a common and potentially fatal infectious disease that typically infects and destroys the lungs and lymphatic system, but can also infect other organs such as the brain, central nervous system, circulatory system, urinary system, bones, joints, and even the skin. Other mycobacteria, such as Mycobacterium bovis, Mycobacterium africanum, Mycobacterium calceum, and Mycobacterium villiforme, can also cause tuberculosis, but usually do not infect healthy adults.
[0003] Existing tuberculosis care sputum suction devices typically employ a simple direct-insertion connection method to ensure a secure connection between the suction tube and the suction tubing and their respective interfaces. However, these traditional connection methods often have some drawbacks, such as insufficient tightness and easy loosening, especially during prolonged use or movement, which may lead to a decrease in airtightness and thus affect the suctioning effect.
[0004] Therefore, a sputum suction device for tuberculosis care is proposed to address the above problems. Utility Model Content

[0037] Reference Figure 1 - Figure 5 An air inlet pipe 22 is fixedly connected to the top of the base 6. A groove 3 21 is provided on the outside of the air inlet pipe 22. The end of the suction pipe 4 away from the air outlet pipe 15 is inserted into the outside of the air inlet pipe 22. A convex ring 3 20 is fixedly connected inside the end of the suction pipe 4 away from the air outlet pipe 15. The convex ring 3 20 is inserted into the groove 3 21. The air inlet pipe 22 is connected to the vacuum pump inside the main body 5 of the sputum suction device, and then connected to the other end of the suction pipe 4 to realize the suction of air into the sputum suction container 7, thereby realizing the sputum suction work. The convex ring 3 20 inside the suction pipe 4 is used to engage with the groove 3 21 to ensure the airtightness of the connection.
[0038] Reference Figure 1 - Figure 3 The suction tube 3 is secured with a retaining ring 2 at the end away from the inlet tube 12. A rubber ring 1 is fixedly connected to the outside of the retaining ring 2. The retaining ring 2 is used to fix the suction tube 3 and the rubber ring 1. The rubber ring 1 is used to put around the user's neck to ensure that the suction tube 3 is not easy to move during suctioning, thereby improving the efficiency of suctioning.
[0039] Working principle: First, pull the pad 16, then insert the T-shaped plug 9 into the fixing block 8. Then release the pin 18. Under the action of the spring 19, the pin 18 will be tightly inserted into the T-shaped plug 9, thus fixing the suction container 7 and preventing accidental movement during suctioning. This also facilitates subsequent cleaning of the suction container 7. Next, insert the suction tube 3 into the outside of the inlet tube 12, until the first convex ring 10 is engaged in the groove 11. Then, insert the suction tube 4 into the outside of the outlet tube 15, until the second convex ring 13 is engaged in the groove 14. Finally, insert the suction tube 4... The other end is inserted into the outside of the air inlet tube 22. During the insertion process, until the convex ring 3 20 is inserted into the groove 3 21, the assembly of the entire device is completed. Through the interference fit of each connection port, the airtightness of the connection can be effectively ensured. Then, by controlling the main body 5 of the sputum suction device, the other end of the suction tube 3 is blocked by hand, and the air pressure value displayed on the main body 5 of the sputum suction device is observed. If the air pressure value does not change, it means that the airtightness of the device is good. Otherwise, it means that the airtightness is not good. Under the condition that the airtightness is good, the rubber ring 1 is put into the user's neck, and then the subsequent sputum suction work is carried out.
