Description

Technical Field

[0001] The present invention relates to the technical field of respiratory tract detection, in particular to a portable mask for respiratory tract cough detection. Background Art

[0002] Currently, medical staff mainly focus on determining the cause of a patient's cough through: 1. Detailed medical history and physical examination; 2. Laboratory tests (such as blood routine, CRP, sputum examination, etc.); 3. Imaging examinations (such as chest CT, X-rays, PET-CT, etc.); 4. Special examinations for specific causes (allergen testing, pulmonary function, bronchoscopy, etc.). Based on the above commonly used clinical cough detection methods, the cause of the cough cannot be determined or there is a problem of false negative cough detection. Considering that some tests are immediate and cannot continuously detect cough, the detection methods have disadvantages.

[0065] By installing the data transmission port 27 , the data collected by the MEMS microphone 11 and the two first MEMS vibration sensors 10 can be conveniently transmitted to the detachable sensing module 9 .

[0066] Example 1

[0067] like Figure 13As shown, the mask bracket 1 is first put on the patient's neck, and then the mask bracket 1 is moved to the position below the patient's head through the elastic band 6. The middle of the front end of the mask bracket 1 is located at the patient's philtrum, and the two ends of the mask bracket 1 and the docking part 2 are located at the rear positions on both sides of the patient's cheeks. At the same time, the elastic band 6 needs to be buckled at the back of the patient's head. Through the elastic force of the elastic band 6, the sensing module mounting bracket 8 and the detachable sensing module 9 can be against the lower end of the patient's neck, so that the device forms a triangle-like positioning. The three positioning points are: the patient's philtrum, the back of the head and the neck.

[0068] The detachable sensing module 9 and the sensing module mounting frame 8 are connected by snap fasteners or screws.

[0069] After the device is fixed, the position of the curved mask 3 is adjusted by the rotating shaft 5. A circle of sound-absorbing cotton 12 is installed inside the curved mask 3. The curved mask 3 mainly covers the patient's mouth. At the same time, the sound-absorbing cotton 12 is used to prevent external sounds from interfering with the internal cough sound. The sound-absorbing cotton 12 is attached to the outer skin of the patient's mouth, so that a cavity is formed between the inner circle of the sound-absorbing cotton 12 and the patient's mouth. The sound-absorbing cotton 12 can prevent external sounds from entering and interfering with the cough sound emitted by the patient. A notch corresponding to the MEMS microphone 11 is provided in the middle position of the upper part of the sound-absorbing cotton 12. At the same time, when the curved mask 3 is closed, the MEMS microphone 11 is inserted into the notch, so that the MEMS microphone 11 can collect the cough sound in the cavity.

[0070] When collecting data, the patient needs to carry the device for 1 to 3 days. When drinking water and eating, the curved mask 3 is rotated downward by rotating the shaft 5, thereby opening the curved mask 3 and exposing the patient's mouth, so that the patient can drink water and eat.

[0072] When it is necessary to judge the pathological condition of the patient, remove the device and the detachable sensing module 9 at the same time. The detachable sensing module 9 is connected to the computer through the data cable interface. The collected data is compared with the data in the database through AI, and a pathology report is given through AI.

[0073] This device is not intended to replace the original blood tests and CT tests. It mainly adds a new detection method to further supplement the detection methods, so that AI can make a more comprehensive judgment on the pathology of the patient.

[0074] The MEMS microphone 11 can convert sound into electrical signals, and at the same time convert the sound signals into ripple patterns through a computer. At the same time, the first MEMS vibration sensor 10, the second MEMS vibration sensor 17 and the third MEMS vibration sensor 18 can convert vibration conditions into ripple patterns, which are used to facilitate and quickly perform graphic comparisons, thereby improving the accuracy, speed and precision of diagnosis.

[0075] Example 2

[0076] When assembling the device, first, a groove or channel for arranging the data line needs to be designed in the mask bracket 1. At the same time, the mask bracket 1, the docking part 2 and the mask docking seat 4 are integrally formed. After completion, the elastic band 6 is installed between the rear ends of the two docking parts 2, and then the MEMS microphone 11 is installed on the mask bracket 1, and the first MEMS vibration sensor 10 is installed on the inner side of the two docking parts 2. After completion, the MEMS microphone 11 and the two first MEMS vibration sensors 10 need to be connected through the data line, and then the arc mask 3 is installed. The two ends of the cover 3 are equipped with a rotating shaft 5, and the rotating shaft 5 and the mask docking seat 4 are docked 2. After completion, the two curved arm structures 7 are installed, and then the two telescopic shafts 23 of the sensing module mounting frame 8 are inserted into the telescopic shaft mounting port 22, the limiting protrusion 24 and the slide groove are docked, and the tension spring structure 26 in the curved arm structure 7 is hooked on the pull rod 25. After completion, the limiting cover 21 is installed, and finally the detachable sensing module 9 is installed on the sensing module mounting frame 8. When in use, the data cable 28 needs to be connected to dock the detachable sensing module 9 with the MEMS microphone 11 and the two first MEMS vibration sensors 10.

[0077] like Figure 14 As shown, the detachable sensing module 9 can be disassembled and assembled, so that the device can connect the collected data to the computer and facilitate centralized analysis and processing of the data through the computer.
