Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an exhaled breath condensate collection mask for tuberculosis detection. Background Technology

[0002] Tuberculosis testing involves a systematic assessment process that differs depending on whether it detects dormant bacteria in the body or confirms an active, infectious lesion. Tuberculosis testing uses a series of medical methods to determine whether a person is infected with Mycobacterium tuberculosis or has developed symptomatic tuberculosis. This is because tuberculosis infection can exist in two states: latent infection and active tuberculosis.

[0003] The collection mask is placed over the patient's mouth to form a physical barrier, blocking the splashing of secretions at the source and protecting the operator and the surrounding environment.

[0004] Currently, commercially available face masks generally only provide basic protection against the splashing of secretions, and their internal structure is relatively simple, making it impossible to collect condensate from the exhaled gases of tuberculosis patients and to quickly remove and reassemble them. Therefore, an improved device is needed to address these issues. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides an exhaled breath condensate collection mask for tuberculosis detection.

The air filter is fixedly installed at equal intervals inside the filter housing. The limiting frame is slidably inserted into the inner side of the filter housing. The extension slide bar slides through the filter housing and connects to the limiting frame.

[0009] Specifically, the receiving device includes a second spring, a sealing arc strip, a vertical guide rod, a horizontal pin, a side bracket, a vertical sleeve, and a receiving cavity.

The second spring is fixedly installed between the bottom of the receiving cavity and the sealing arc strip. The side bracket is fixedly installed at both ends of the receiving cavity. The horizontal pin is fixedly installed at the top of the side bracket.

[0010] Specifically, the positioning device includes an exhalation mask, an arc groove, an intercepting edge strip, a side end guard plate, a longitudinal edge strip, a transverse edge strip, a guide sleeve, a positioning rod, an extension base frame, a third spring, and a bottom sleeve. The transverse edge strip is fixedly installed at the top and bottom of the front end of the exhalation mask. The side end guard plate is fixedly installed at both ends of the exhalation mask. The longitudinal edge strip is symmetrically fixedly installed between the two transverse edge strips. The arc groove is formed at the bottom of the transverse edge strip. The intercepting edge strip is fixedly installed at the top of the transverse edge strip. The guide sleeve is fixedly installed at the bottom of the side end guard plate. The bottom sleeve is fixedly installed at the bottom of the guide sleeve. The third spring is fixedly installed at the bottom of the inner end of the bottom sleeve. The positioning rod slides through the guide sleeve and the bottom sleeve and is connected to the third spring. The extension base frame slides through the side end of the bottom sleeve and is connected to the positioning rod.

[0011] Specifically, the positioning cavity is fixedly installed on the inner wall of the side end guard plate, the filter element shell is fixedly installed on the outer side of the side end guard plate, and the filter element shell is located above the guide sleeve. The transverse pin is slidably inserted into the inside of the guide sleeve, and the sealing arc strip is slidably inserted into the bottom end of the arc groove.

[0012] Specifically, the filter element housing has a through hole on the side facing away from the limiting frame, a return spring is fixedly installed inside the filter element housing and the filter element housing is connected to the return spring, the extension slide rod is vertically aligned with the extension base frame, the contact vertical rod is vertically aligned with the top of the extension slide rod, the bottom of the filter element housing near the limiting frame has a through hole, the positioning cavity is hollow inside, and sliding grooves are provided on both sides of the positioning cavity.

[0013] Specifically, the surface of the scraper is in contact with the surface of the exhalation mask near the intercepting edge strip, the side end of the side guard plate is provided with a sliding groove, the inside of the guide sleeve is provided with a slot, the side end of the bottom sleeve is provided with a vertical groove that matches the extension base, and the inside of the transverse pin and the inside of the guide sleeve are both provided with round holes.

[0014] Specifically, the receiving cavity also includes an extension discharge pipe, a sealing head, a threaded rod, and an extension frame.

[0015] The beneficial effects of this invention are:

[0016] First, this invention, through the design of the exhalation mask, facilitates the contact of the patient's exhaled air with its inner wall until the air condenses on the inner wall of the exhalation mask. Simultaneously, when the synchronizing rod moves downward, it can drive the scraper to move downward along the inner wall of the exhalation mask, allowing the condensate to be scraped away. Through the contact between the guide rod at the bottom of the scraper and the sealing arc strip, the sealing arc strip can be squeezed downward, so that the condensate can enter the interior of the receiving cavity for collection. Furthermore, when the guide rod is not in contact with the sealing arc strip, the second spring can drive the sealing arc strip to seal the arc groove, preventing excessive exhaled air from entering the interior of the receiving cavity. This completes the cleaning of the inner wall of the exhalation mask while collecting the condensate.

[0017] Second, when the synchronous rod moves downward, it can drive the contact vertical rod to contact the extension slide rod, so that the compressible limiting frame can move downward, making it easier for the user to take out the air filter inside the filter housing. At the same time, when the extension slide rod moves downward to its limit position, it can also compress the extension base frame to move downward, so that the extension base frame can drive the positioning rod to be pulled out from the inside of the guide sleeve and the transverse pin, releasing the transverse pin. Then, the storage cavity can be pulled to the side, so that the storage cavity can be removed from the bottom of the exhalation mask. Furthermore, through the setting of the third spring, the positioning rod can be driven to reset in time when it is not under pressure, completing the quick installation and removal work.

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an exhaled condensate collection mask for tuberculosis detection according to the present invention includes a support component 2. A displacement device 1 is fixedly installed inside the support component 2. Connecting rings 3 are symmetrically fixedly installed at both ends of the support component 2.

[0033] like Figure 4 The support component 2 includes an auxiliary device 11, a receiving device 12, and a positioning device 13.

[0034] like Figure 5 The auxiliary device 11 includes an extension slide rod 14, a limiting frame 15, a filter housing 16, and an air filter 17. The air filter 17 is fixedly installed inside the filter housing 16 at equal intervals. The limiting frame 15 is slidably inserted into the inner side of the filter housing 16. The extension slide rod 14 slides through the filter housing 16 and is connected to the limiting frame 15. When the extension slide rod 14 moves downward, it can drive the limiting frame 15 to move downward until it is misaligned with the bottom of the air filter 17, so that the air filter 17 can be easily removed from the inside of the filter housing 16.

[0035] like Figure 6 The receiving device 12 includes a second spring 18, a sealing arc strip 19, a vertical guide rod 20, a horizontal pin 21, a side end bracket 22, a vertical sleeve 23, and a receiving cavity 24. The vertical sleeves 23 are fixedly installed at equal intervals at the bottom of the inside of the receiving cavity 24, and the vertical sleeves 23 are arranged in a ring.

The vertical guide rod 20 can slide up and down inside the vertical sleeve 23, so as to support the up and down movement of the sealing arc strip 19.

[0036] like Figure 7 and Figure 8 The positioning device 13 includes an exhalation mask 25, an arc groove 26, an intercepting edge strip 27, a side end guard plate 28, a longitudinal edge strip 29, a transverse edge strip 30, a guide sleeve 31, a positioning insert rod 32, an extension base frame 33, a third spring 34, and a bottom end sleeve 35. The transverse edge strip 30 is fixedly installed at the top and bottom of the front end of the exhalation mask 25. The side end guard plate 28 is fixedly installed at both ends of the exhalation mask 25. The longitudinal edge strip 29 is symmetrically fixedly installed between the two transverse edge strips 30. The arc groove 26 is formed at the bottom end of the transverse edge strip 30. The intercepting edge strip 27 is fixedly installed on the transverse edge strip 30. At the top of the side strip 30, the guide sleeve 31 is fixedly installed at the bottom of the side end of the side end guard plate 28, the bottom sleeve 35 is fixedly installed at the bottom end of the guide sleeve 31, the third spring 34 is fixedly installed at the bottom inside of the bottom sleeve 35, the positioning rod 32 slides through the guide sleeve 31 and the bottom sleeve 35 and is connected to the third spring 34, and the extension base 33 slides through the side end of the bottom sleeve 35 and is connected to the positioning rod 32. The transverse side strip 30 and the longitudinal side strip 29 fit the patient's facial surface, so that air leakage can be avoided when wearing the exhalation mask 25.

[0037] The positioning cavity 8 is fixedly installed on the inner wall of the side end guard plate 28, and the filter element housing 16 is fixedly installed on the outer side of the side end guard plate 28, with the filter element housing 16 located above the guide sleeve 31. The transverse pin 21 is slidably inserted into the inside of the guide sleeve 31, and the sealing arc strip 19 is slidably inserted into the bottom end of the arc groove 26. A through hole is opened on the side end of the filter element housing 16 away from the limiting frame 15. A return spring is fixedly installed inside the filter element housing 16, and the filter element housing 16 is connected to the return spring. The extension slide rod 14 is vertically aligned with the extension base frame 33 and contacts the vertical rod. The top of the extension slide bar 14 is vertically aligned with the top of the filter housing 16 near the bottom of the limiting frame 15. The positioning cavity 8 is hollow inside, and sliding grooves are provided on both sides of the positioning cavity 8. The surface of the scraper 10 is in contact with the surface of the exhalation mask 25 near the intercepting edge strip 27. The side end of the side guard plate 28 is provided with a sliding groove. The inside of the guide sleeve 31 is provided with a slot. The side end of the bottom sleeve 35 is provided with a vertical groove that matches the extension base frame 33. The inside of the transverse pin 21 and the inside of the guide sleeve 31 are both provided with round holes.

[0038] The working principle of Example 1 is as follows: In use, first install the elastic band on the connecting ring 3, then move the exhalation mask 25 to the patient's face. The elastic band can then be wrapped around the patient's head and neck to allow the exhalation mask 25 to be worn. The longitudinal side strips 29 and transverse side strips 30 ensure a snug fit against the patient's face, preventing air leakage at the junction of the exhalation mask 25 and the patient's face. An air inlet is provided at the bottom of the side end of the side panel 28, with the air filter 17 located outside the air inlet. This allows air to be filtered by the air filter 17 before entering the exhalation mask 25 for the patient to inhale. Subsequently, some of the patient's exhaled air accumulates inside the exhalation mask 25, while some is discharged through the air inlet. The air remaining inside the exhalation mask 25 can condense and adhere to the surface. When sufficient condensate accumulates on the inner wall of the exhalation mask 25, the synchronizing rod 4 can be pressed downwards, causing the L-shaped extension rod 5 to move the scraper 10 downwards via the displacement latch 9. The scraper 10 then adheres to the inner wall of the exhalation mask 25, allowing it to scrape away the condensate. The condensate then flows downwards along the interior of the exhalation mask 25. A guide rod is fixedly installed at the bottom of the scraper 10, perpendicularly aligned with the sealing arc strip 19. When the scraper 10 moves downwards to its limit, the guide rod can compress the sealing arc strip 19, causing it to move out of the arc groove 26. At this point, the condensate can enter and accumulate inside the receiving cavity 24, and then slide down via the vertical guide rod 20. The movable insertion is inside the top of the vertical sleeve 23, allowing the sealing arc strip 19 to move up and down to complete the recovery of condensate from the exhaled gas of tuberculosis patients. Simultaneously, when the synchronizing rod 4 moves downward to its limit position, the contact vertical rod 6 can compress the extension slide rod 14 to move downward to its limit position, thus preventing the top of the limiting frame 15 from misaligning with the bottom of the air filter element 17. This allows the user to easily remove the air filter element 17 from the filter element housing 16. At the same time, when the extension slide rod 14 moves downward to its limit position, it can also compress the extension base frame 33 to move downward to its limit position, allowing the positioning insertion rod 32 to be pulled out from inside the guide sleeve 31 and the transverse pin 21, releasing the transverse pin 21. When a certain amount of condensate accumulates inside the receiving cavity 24... When emptying the condensate, the receiving chamber 24 can be pulled away from the end of the exhalation mask 25 until the horizontal pin 21 is completely pulled out from the inside of the guide sleeve 31. This allows the receiving chamber 24 to be detached from the exhalation mask 25, facilitating the transfer of the condensate inside the receiving chamber 24. After the condensate inside the receiving chamber 24 has been emptied, the horizontal pin 21 can be reinserted into the guide sleeve 31, allowing the receiving chamber 24 to be installed at the bottom of the exhalation mask 25. Then, the synchronizing rod 4 is released. The elasticity of the first spring 7 will cause the displacement latch 9 to move upward, thereby causing the synchronizing rod 4 to return to its original position. When the synchronizing rod 4 returns to its original position, the contact vertical rod 6 can disengage from the extension slide rod 14, thanks to the return spring installed inside the filter housing 16.This allows the reset spring to move the limiting frame 15 upwards to reset, and the limiting frame 15 can again block and limit the air filter element 17. Furthermore, after the extension slide rod 14 resets, the elasticity of the third spring 34 will move the extension base frame 33 upwards to reset, allowing the positioning rod 32 to be inserted into the guide sleeve 31 and the transverse pin 21, thus fixing the receiving cavity 24. Simultaneously, when the synchronizing rod 4 resets upwards, the guide rod at the bottom of the scraper 10 can disengage from the sealing arc strip 19, and the elasticity of the second spring 18 will move the... The sealing arc strip 19 quickly returns to its upward position, allowing it to seal the inside of the arc groove 26, thus completing the operation. During use, the device slides within the movable groove of the positioning cavity 8 via the displacement latch 9, ensuring the synchronous rod 4 moves vertically in a straight line. Simultaneously, a through hole at the bottom of the filter housing 16 allows the extension slide 14 to move the limiting frame 15 downwards. The intercepting edge strip 27 prevents condensate from seeping outwards along the bottom of the exhalation mask 25, thus completing the operation.

[0039] Example 2

[0040] Based on Example 1, such as Figure 9 As shown, the receiving cavity 24 also includes an extension discharge pipe 36, a sealing head 37, a threaded rod 38, and an extension frame 39. The extension discharge pipe 36 is fixedly installed on the side end of the receiving cavity 24, the extension frame 39 is fixedly installed on the side end of the extension discharge pipe 36 away from the receiving cavity 24, the threaded rod 38 is threaded into the center of the side end of the extension frame 39, and the sealing head 37 is fixedly installed on the end of the threaded rod 38 near the receiving cavity 24.

[0041] In implementing this embodiment, when it is necessary to empty the condensate inside the receiving cavity 24, the threaded rod 38 can be rotated so that the sealing head 37 can be pulled out from the inside of the extended discharge pipe 36. The extended discharge pipe 36 communicates with the inside of the receiving cavity 24, allowing the condensate inside the receiving cavity 24 to be discharged outward from the extended discharge pipe 36. After the condensate inside the receiving cavity 24 has been completely discharged, the threaded rod 38 can be rotated in the opposite direction so that the sealing head 37 can enter the inside of the extended discharge pipe 36 and seal the extended discharge pipe 36. This allows the receiving cavity 24 to accumulate condensate again, thus completing the work.
