[0030] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0031] Unless otherwise specified or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0032] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0033] This utility model proposes a device 100 for detecting Eustachian tube function, such as... Figures 1 to 3 As shown, the system includes: a control host 1, a first detection module 2, and a second detection module 3. The first detection module 2 includes a first connecting pipe 21, a second connecting pipe 23, a first sealing plug 22, and a second sealing plug 24. The first sealing plug 22 is connected to the first end of the first connecting pipe 21, and the second end of the first connecting pipe 21 is connected to the control host 1. The second end of the first connecting pipe 21 has a first sensing end. The second sealing plug 24 is connected to the first end of the second connecting pipe 23, and the second end of the second connecting pipe 23 is connected to the control host 1. The second end of the second connecting pipe 23 has a second sensing end. The second detection module 3 includes a contact sensor 33 and a data cable 31. The contact sensor 33 is connected to the first end of the data cable 31, and the second end of the data cable 31 is electrically connected to the control host 1. The contact sensor 33 has a third sensing end.

[0034] Specifically, the first sealing plug 22 is placed at the nasal opening of the subject to seal the nasal cavity; the second sealing plug 24 is placed at the external auditory canal opening of the subject to seal the external auditory canal. During actual testing, to test the function of the Eustachian tube in the same direction as the designated external auditory canal, the second sealing plug 24 needs to be placed at the external auditory canal opening to be tested. The second end of the first connecting tube 21 is used to output a preset air pressure, and the first sensing end of the first connecting tube 21 is used to sense the output air pressure value of the first connecting tube 21. This preset air pressure enters the nasopharynx. When the subject swallows saliva, the nasopharynx connects with the external auditory canal, and the second end of the second connecting tube 23 will generate actual air pressure. The second sensing end of the second end of the second connecting tube 23 is used to sense this actual air pressure value. When the Eustachian tube is diseased, there will be a significant change in the pressure values ​​at the second sensing end and the first sensing end, thereby determining whether the Eustachian tube is diseased.

[0035] Furthermore, during the test, the contact sensor 33 is placed in the subject's throat. When the subject swallows, pressure changes occur in the subject's throat, and the contact sensor 33 is used to detect these pressure changes. The data generated by the contact sensor 33 can determine whether the subject has swallowed, thereby objectively expressing the accuracy of the test and avoiding detection errors in the Eustachian tube function testing device 100.

[0036] In some embodiments, the first sealing plug 22 and the second sealing plug 24 are connected or disconnected, the first sensing end has a first detection value, and the second sensing end has a second detection value; when the first sealing plug 22 and the second sealing plug 24 are connected, the first detection value is greater than or equal to the second detection value; when the first sealing plug 22 and the second sealing plug 24 are disconnected, the first detection value is greater than the second detection value. Specifically, before the subject swallows, the first sealing plug 22 and the second sealing plug 24 are disconnected, the first connecting tube 21 delivers gas to the nasopharynx, and the pressure at the nasopharynx is detected as the first detection value, which is greater than the second detection value; after the subject swallows, the first sealing plug 22 and the second sealing plug 24 are connected, and the gas from the nasopharynx is sequentially output to the external auditory canal and the second connecting tube 23, and the pressure in the external auditory canal is detected as the second detection value. If the Eustachian tube function is normal, then the first detection value and the second detection value are equal; if the Eustachian tube is abnormal, then the first detection value is greater than the second detection value, thereby determining whether the subject's Eustachian tube is diseased. The contact sensor 33 can accurately detect whether the subject has swallowed, reducing the steps doctors need to take in questioning the subject and improving detection efficiency and accuracy.

[0037] In addition, the control host 1 includes a circuit board 10, an air pump, a first sensor 107, and a second sensor 108. The air pump is connected to the second end of the first connecting pipe 21. The first sensor 107 and the second sensor 108 are mounted on the circuit board 10. The first and second sensors sense the air pressure in the first and second connecting pipes. The circuit board 10 is electrically connected to the data processor 4. The first sensor 107 is used to detect a first detection value at the first sensing end, and the second sensor 108 is used to detect a second detection value at the second sensing end. In this embodiment, the air pump, the first sensor 107, and the second sensor 108 are conventional components that can be purchased from the market.

[0038] Preferably, the second detection module 3 includes a fixing ring 32 and a latch 322. A contact sensor 33 is mounted on the fixing ring 32. The two ends of the latch 322 are connected to the beginning and end of the fixing ring 32, respectively. The latch 322 is a detachable structure, and the fixing ring 32 and the latch 322 together form a ring structure. Specifically, the fixing ring 32 has a receiving groove 321. The fixing ring 32 is used to be placed around the neck of the subject. When a swallowing action occurs in the throat, the fixing ring 32 will vibrate or be squeezed, and the swallowing action will also produce sound. The fixing ring 32 transmits the sound and pressure from the throat to the sensing end of the contact sensor 33, and the contact sensor 33 transmits the data to the data processor 4. The data processor 4 is used to analyze the pressure value and sound wave value, and generate a curve graph for the testing personnel to observe and analyze.

[0039] Preferably, the latch 322 includes a first fastening member and a second fastening member. The first end of the first fastening member is mounted on the first end of the fixing ring 32, and the first end of the second fastening member is mounted on the tail end of the fixing ring 32. The second ends of the first and second fastening members engage with each other. The latch has a control circuit, which is electrically connected to a contact sensor. Specifically, the control circuit can be located on the first and second fastening members. When the first and second fastening members are engaged, the control circuit is activated, and the contact sensor 33 is turned on. When the first and second fastening members are disengaged, the contact sensor 33 is turned on and off.

[0040] Preferably, the first sealing plug 22 includes two plug heads, each plug head having a connection hole, and the two connection holes of the two plug heads are connected in parallel with the first connecting tube 21. The two plug heads are used to seal with the two nostrils of the nasopharynx to prevent gas from leaking from the nasopharynx through the first connecting tube 21, and to ensure that the air pressure value sensed by the first sensing end is consistent with the output air pressure value.

[0041] Preferably, the Eustachian tube function testing device 100 further includes a data processor 4, which is a PC with testing software. The control host 1 has a pressure regulator 105 and a pressure gauge 104. The pressure regulator 105 is connected to the second end of the first connecting tube 21, and the pressure gauge 104 is connected to the third end of the first connecting tube 21. The pressure regulator 105 and the pressure gauge 104 are also electrically connected to the data processor 4. Specifically, the pressure gauge 104 is used to display the output pressure value in the first connecting tube 21, that is, to display the data of the first detection value, while the pressure regulator 105 is used to adjust the output pressure value of the first connecting tube 21. According to the adjustment of the pressure regulator 105, the air pump can output the corresponding pressure to the first connecting tube 21 as needed.

[0042] In addition, the control host 1 also has a power indicator light 101, a switch 102, and a pressure calibration knob 103. The indicator light 101, the switch 102, and the pressure calibration knob 103 are electrically connected through a circuit board 10. The pressure calibration knob 103 is used to adjust the pressure display at the second connecting pipe 23. When the switch 102 is turned on, the power indicator light 101 lights up, indicating that the operator can operate the pressure calibration knob 103.

[0043] Preferably, both the first sealing plug 22 and the second sealing plug 24 are provided with flexible components. Specifically, the flexible components are used to conform to the external tissue of the human body, so as to achieve a flexible seal between the first sealing plug 22 and the nostril, and a flexible seal between the second sealing plug 24 and the external auditory canal, thereby improving the sealing performance and also improving the comfort of the subject wearing the Eustachian tube function testing device 100.

[0044] Preferably, the control unit 1 also includes a filter 25, with a first end connected to the second end of the first connecting tube 21 and a second end connected to the third end of the first connecting tube 21. Specifically, this filter 25 is used to filter the air in the nasopharynx. When the subject swallows, the air in the first connecting tube 21 enters the second connecting tube 23 through the Eustachian tube. The filter 25 filters the air in the second connecting tube 23 to prevent contaminated air from entering other pipes in the control unit 1.

[0045] Preferably, the control unit 1 includes a housing 11 and a sealing plate 12. The housing 11 has a mounting groove 141, in which the filter 25 is installed. The sealing plate 12 is detachably installed at the opening of the mounting groove 141. Specifically, after the Eustachian tube function testing device 100 has been used for a period of time, the filter 25 will accumulate a lot of dirt and needs to be replaced periodically. By removing the sealing plate 12, the opening of the mounting groove 141 is exposed, the filter 25 that needs to be replaced is taken out, a new filter 25 is replaced, and then the sealing plate 12 is reinstalled. This avoids completely removing the control unit 1 to replace the filter 25, improving the convenience of maintenance.

[0046] Preferably, the sealing plate 12 has a locking block 121 and a fixing end 122. The control host 1 has a mounting box 14 and a sealing ring 13. The mounting box 14 is installed inside the housing 11, and a mounting groove 141 is formed inside the mounting box 14. The sealing ring 13 is installed on the mounting box 14. The housing 11 has a locking groove 112 that cooperates with the locking block 121. The sealing plate 12 is installed on the housing 11 and is used to abut against the mounting box 14. The sealing ring 13 is disposed between the sealing plate 12 and the mounting box 14. Specifically, the cooperation between the locking block 121 and the locking groove 112 improves the stability of the sealing plate 12 and the housing 11. Moreover, the housing 11 also has a mounting hole 111. This mounting hole 111 and the fixing end 122 allow screws to pass through, so that the sealing plate 12 is fixed on the housing 11. The sealing ring 13 is disposed between the sealing plate 12 and the mounting box 14, improving the sealing performance of the mounting groove 141.

[0047] Preferably, filter 25 includes a porous activated carbon structure. The effectiveness of activated carbon in filtering air depends primarily on its adsorption capacity, the environment in which it is used, and the quality of the activated carbon. Activated carbon has a highly developed pore structure and a large specific surface area, and is typically made from carbonaceous raw materials (such as wood, coal, coconut shells, etc.) through carbonization and activation processes. Its surface contains abundant micropores, mesopores, and macropores, relying on both physical and chemical adsorption mechanisms to remove harmful gases.
