Description

Technical Field

[0001] This utility model relates to the technical field of lung examination equipment, and in particular to an examination mouthpiece and lung function testing instrument. Background Technology

[0002] Pulmonary function tests are essential for respiratory diseases, primarily used to assess airway patency and lung capacity. Currently, pulmonary function tests often require patients to bite down on the bite plate. However, existing bite plate structures are relatively simple, requiring patients to bite down hard to prevent the bite plate from slipping out of their mouths. Elderly individuals, due to tooth loss, may be unable to close their mouths tightly during the test, leading to air leakage from the corners of their mouths, making it difficult to complete the test. Furthermore, air leakage from the corners of the mouth can result in poor cooperation during the test, affecting the test results.

[0003] The prior art patent with publication number CN218304901U discloses a mouthpiece and lung function testing device for lung function testing. It achieves a leak-proof effect by having a gingival air-sealing ring contact and fit with the inside of the patient's gums, and the patient's tongue abutting against the gingival air-sealing ring. However, in actual use, it is difficult for the elderly to perform standardized operation, and air leakage is still likely to occur. The overall practicality is low. In order to address the above problems, a mouthpiece and lung function testing device is proposed. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figures 1-4 The inspection mouthpiece shown includes a sealing cover 1, an air inlet hole is provided on the inner wall of the periphery of the sealing cover 1, an air inlet pipe 2 is sealed and installed in the air inlet hole, and a mouth-holding mechanism is detachably installed at the end of the air inlet pipe 2 to assist the user in blowing air.

[0024] The mouthpiece mechanism includes a mouthpiece tube 3. One end of the mouthpiece tube 3 is connected to the air inlet tube 2 via a plug-in assembly. A lower dental sleeve 5 is fixedly installed on the outer periphery of the mouthpiece tube 3. A lower dental groove 6 is provided at the bottom of the lower dental sleeve 5. An upper dental sleeve 7 is provided at the top of the lower dental sleeve 5 via two telescopic assemblies. An upper dental groove 11 is provided at the top of the upper dental sleeve 7. A first sealing assembly is provided between the lower dental sleeve 5 and the upper dental sleeve 7. A second sealing assembly is provided between the mouthpiece tube 3 and the upper dental sleeve 7.

[0025] With the above structure, during normal use, the air blowing test function can be achieved by simply using the sealing cover 1. When the elderly need to use it, the mouth tube 3 is first connected to the air inlet tube 2 through the plug-in component, and the lower dental bracket 5 and the upper dental bracket 7 are moved relative to each other by pressing, so that the lower dental bracket 5 and the upper dental bracket 7 can be placed in the mouth, so that the upper gum and the lower gum are respectively in contact with the inner walls of the upper pressure groove 11 and the lower pressure groove 6. During the closing process, the cooperation of the first sealing component and the second sealing component can achieve the sealing function and improve the use effect.

[0026] like Figure 2 As shown, the insertion assembly includes an insertion tip 4. By setting one end of the insertion tip 4 as a tip, it is easier to insert and more convenient to operate. The insertion tip 4 is fixedly installed at the end of the mouthpiece 3, and the outer peripheral wall of the insertion tip 4 is in contact with the inner peripheral wall of the air inlet pipe 2.

[0027] Specifically, by inserting the tip tube 4, it is easier for the mouthpiece tube 3 to connect to the air inlet tube 2, making it more convenient for users to operate.

[0028] like Figure 4 As shown, the telescopic assembly includes two bushings 8. Circular grooves are provided on the opposite sides of the lower dental brace 5 and the upper dental brace 7. The two bushings 8 are fixedly installed in the two circular grooves respectively. A telescopic shaft 9 is slidably installed in both bushings 8. An elastic unit is sleeved on the outer periphery of the telescopic shaft 9. By sliding the telescopic shaft 9 in the bushings 8, it is easy for the lower dental brace 5 and the upper dental brace 7 to bite together. Furthermore, the position can be easily adjusted by the elastic action of the return spring 10. The elastic unit includes a return spring 10, which is sleeved on the telescopic shaft 9. The two ends of the return spring 10 are fixedly installed on the opposite sides of the lower dental brace 5 and the upper dental brace 7 respectively.

[0029] Specifically, the telescopic shaft 9 slides within the two bushings 8, facilitating the engagement of the lower brace 5 and the upper brace 7. Furthermore, the elasticity of the return spring 10 allows for easy adjustment of the brace position, resulting in greater comfort during use.

[0030] like Figure 3 , Figure 4As shown, the first sealing assembly includes two arc-shaped sealing gaskets 12. The top of the lower dental sleeve 5 has two mounting grooves, and the two arc-shaped sealing gaskets 12 are fixedly installed in the two mounting grooves respectively. The bottom of the upper dental sleeve 7 has two arc-shaped sealing grooves 13, and the two arc-shaped sealing gaskets 12 are adapted to the two arc-shaped sealing grooves 13 respectively. The second sealing assembly includes a semi-circular sealing gasket 14, which is fixedly installed on the outer peripheral wall of the mouthpiece tube 3. The inner peripheral wall of the upper dental sleeve 7 has a semi-circular sealing groove 15, and the semi-circular sealing gasket 14 is adapted to the semi-circular sealing groove 15. By setting the arc-shaped sealing gaskets 12 and the semi-circular sealing gaskets 14, the sealing ability during air blowing can be improved, preventing air leakage.

[0031] Specifically, during engagement, the sealing function of the two arc-shaped sealing gaskets 12 and the semi-circular sealing gasket 14 can further improve the sealing performance and effectively prevent air leakage.

[0032] A pulmonary function testing device includes a pulmonary function testing device body, and the air inlet tube of the pulmonary function testing device body is connected to an examination mouthpiece, which is the aforementioned examination mouthpiece.
