Description

Technical Field

[0001] The present invention relates to the technical field of sleep breathing detection, and more specifically, to an intelligent sleep breathing detection device and its application method. Background Art

[0002] Obstructive sleep apnea hypopnea syndrome (SAHS), as a serious sleep disorder disease, poses a major threat to the quality of life and even the life safety of patients. To solve this problem, many devices based on various types of sensors (such as respiratory rate, heart rate, blood oxygen, etc.) have emerged on the market currently. However, a major defect of these types of devices is poor portability, and it is easy to get the wires tangled when turning over during use, which affects sleep.

[0003] Chinese Application, Application No. CN202310652204.2 provides a wireless sleep breathing monitor, which is attached to the position under the human nose in a way similar to a nasal sticker and uses wireless transmission to improve portability. Although it can solve this problem to a certain extent, there is still a relatively high risk of detachment with this attachment method. Once detached, the monitoring effect is completely lost. At the same time, the vibration piece set is relatively large in volume and is basically perpendicular to the angle of exhaled air during human breathing. This will cause a large part of the exhaled air to rebound when contacting the vibration piece, and the comfort during use is relatively poor. Most importantly, this structure can only detect whether exhalation has occurred, cannot detect inhalation, nor can it detect the specific intensity value of each breath. The existing detection of the specific intensity value of breathing still relies on algorithm calculation, which is difficult to develop and the accuracy of the data is prone to errors. What is needed is a sleep breathing detection device and its application method that are not easily detached, have better comfort, and can specifically detect the intensity of each breath.

[0022] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] The intelligent sleep breathing detection device of the preferred embodiment of the present invention, as Figure 1 shown, and referring to Figure 2 and Figure 3 , includes a V-shaped nose bridge cover that matches the human nose bridge. The nose bridge cover is composed of a first cover plate 1 and a second cover plate 2 that are rotationally connected by a damping plate 3 in a damped manner; both the first cover plate 1 and the second cover plate 2 are provided with adhesive films, and the first cover plate 1 and the second cover plate 2 are also connected to the head by a binding strap 4;

[0024] The lower sides of the first cover plate 1 and the second cover plate 2 are both connected with a bent detection piece 6 through a rotating shaft 5. A light torsion spring for resetting the detection piece 6 is arranged on the rotating shaft 5. Avoidance slots 10 for avoiding the detection piece are arranged at the lower ends of the first cover plate 1 and the second cover plate 2. The rotating shaft 5 is located in the corresponding avoidance slots 10, and a piezoelectric film sensor 11 is arranged in the avoidance slots 10; the bent part of the detection piece 6 is rotationally connected with the rotating shaft 5. The two end feet of the detection piece 6 are of different lengths, and the longer end foot 60 extends to the human nostril, and the shorter end foot 61 is connected to and acts on the corresponding piezoelectric film sensor 11; a processor chip 30, a micro battery 31 and a wireless transmission chip 32 are arranged on the damping plate 3. The wireless transmission chip 32 is used for receiving the signals generated by the two piezoelectric film sensors 11 and sending them to an external detection host;

[0025] During application, after the first cover plate 1 is attached to one side of the human nose bridge through an attachment film, the angle of the second cover plate is adjusted, and the second cover plate 2 is attached to the other side of the human nose bridge through an attachment film to complete the fixation, and then a secondary binding fixation with the human head is carried out through the binding belt 4;

[0026] Detection starts. Every time when exhaling or inhaling, the generated airflow will drive the longer end foot 60 of the detection piece 6 to deflect. The shorter end foot 61 of the detection piece 6 deflects accordingly and amplifies the output torque according to the lever principle. The shorter end foot of the detection piece 6 acts on the piezoelectric film sensor 11, causing the piezoelectric film sensor 11 to deform and generate an electrical signal. The wireless transmission chip 32 receives the electrical signals generated by the two piezoelectric film sensors 11 and sends them to an external detection host;

[0027] Applying the method of the present application is not only light and convenient, but also releases the wire bondage and can effectively ensure the reliability of wearing. It is not easy to shift and fall off even when turning over many times during sleep. At the same time, a special detection piece is used to capture the breathing airflow, and the torque generated by the breathing airflow is further amplified according to the lever principle. Then, the piezoelectric film sensor is used to convert the amplified torque into an electrical signal and output it to the processor chip for processing, and then sent to an external detection host by the wireless transmission chip. The intensity data of each exhalation and each inhalation can be collected more accurately, providing the first-hand valuable breathing intensity data for the subsequent monitoring and protection data processing of sleep apnea hypopnea syndrome, and greatly improving the accuracy and precision of monitoring.

[0028] Preferably, the detection piece 6 includes a bent main body rod. The main body rod 62 is rotationally connected with the rotating shaft 5; the first blade 63 and the second blade 64 are rotationally distributed on both sides of the long side (i.e., the longer end foot 60) of the main body rod 62; a limiting and anti-detaching component for limiting the rotation angle of the first blade 63 and the second blade 64 and preventing detachment is arranged on the long side of the main body rod 62;

[0029] With this structural design, the main body rod 62 can be made relatively thin and light, reducing weight. At the same time, the blades can better detect the air flow intensity. Two blades are adopted and configured to rotate. The angle of the blades is limited by a limit and anti-disconnection component. With this setting, the angle of the blades to withstand the air flow can be adjusted according to the actual situation of different individuals. For example, for an adult man, the air flow intensity during breathing is relatively large, so the rotatable angle of the blades can be designed to be larger to reduce the resistance to inhalation and exhalation while meeting the detection requirements. For a child, the rotatable angle of the blades can be designed to be smaller accordingly to mainly meet the detection requirements.

[0030] For the specific setting, normal sleep breathing curve sampling can be carried out first, that is, under normal sleep conditions, collect the breathing intensity data of people in different age groups, and generate an intensity value range corresponding to the age based on the data, and adjust the rotatable angle of the blades according to this intensity value.

[0031] Of course, this setting is a basic setting. For a specific individual, fine-tuning needs to be carried out according to the situation. The fine-tuning method can be as follows: First, perform the above basic setting, then conduct in-hospital detection, further adjust the intensity value range based on the data monitored during hospitalization and the observation results of the doctor's ward rounds, and then you can be discharged home for self-monitoring.

[0032] Preferably, the long side of the main body rod 62 is flat, and a U-shaped groove 620 is opened at the lower end. The first blade 63 and the second blade 64 are respectively rotatably sleeved on the two side edges of the U-shaped groove 620. The limit and anti-disconnection component includes a connecting seat 65 that is detachably connected to the lower end of the long side of the main body rod 62 to block the opening of the U-shaped groove 620. The connecting seat 65 is provided with a first flexible limit piece 650, a second flexible limit piece 651, a third flexible limit piece, and a fourth flexible limit piece. The first flexible limit piece 650 and the second flexible limit piece 651 are respectively located on the front side and the rear side of the first blade 63, and first limit grooves corresponding to the first blade 63 are provided on both the first flexible limit piece 650 and the second flexible limit piece 651. The third flexible limit piece and the fourth flexible limit piece are respectively located on the front side and the rear side of the second blade 64, and second limit grooves corresponding to the second blade 64 are provided on both the third flexible limit piece and the fourth flexible limit piece.

[0033] With this design, the connecting seat 65 blocks the opening of the U-shaped groove 620, preventing the first blade and the second blade from falling out. At the same time, the connecting seat can be disassembled and assembled to quickly replace the first blade and the second blade. While the first flexible limiting piece 650 and the second flexible limiting piece 651 further protect the first blade against falling out, they also limit the forward and backward rotation angles of the first blade to achieve angle limitation. When the angle needs to be adjusted, just replace the connecting seat 65 with the first flexible limiting piece 650 and the second flexible limiting piece 651 of different widths. Similarly, the third flexible limiting piece and the fourth flexible limiting piece are the same.

[0034] Preferably, a connecting ring 66 for connecting the upper ends of the first flexible limiting piece, the second flexible limiting piece, the third flexible limiting piece and the fourth flexible limiting piece by a buckle is arranged on the long side of the main body rod 62; two card holes are arranged on the connecting seat 65, and card joints for cooperating with the card holes are arranged at the ends of the two side edges of the U-shaped groove; it is convenient to disassemble and assemble and has good integrity.

[0035] Preferably, damping rotating shafts are arranged on both sides of the damping plate 3, and the two damping rotating shafts are respectively connected to the first cover plate 1 and the second cover plate 2; the damping rotating shaft includes a first rotating cylinder 33, a second rotating cylinder 34, a damping piece 35 and a connecting shaft 36. The first rotating cylinder 33 and the second rotating cylinder 34 jointly form a damping force by extrusion with the damping piece 35. The first rotating cylinder 33, the second rotating cylinder 34 and the connecting shaft 36 are all made of stainless steel. The connecting shaft 36 sequentially passes through the first rotating cylinder 33, the damping piece 35 and the second rotating cylinder 34; the first rotating cylinder 33 (corresponding to connecting the first cover plate 1 or the second cover plate 2) is electrically connected to the output end of the piezoelectric film sensor 11, and the second rotating cylinder 34 (corresponding to connecting the damping plate 3) is electrically connected to the input end of the processor chip 30. The processor chip 30 is electrically connected to the wireless transmitting chip 32; while the two damping rotating shafts play a role in rotatably connecting the damping plate 3 and the first cover plate 1 and the second cover plate 2, they are also used for electrical connection, which can effectively simplify the structure.

[0036] A method for applying an intelligent sleep apnea detection device is applied to the intelligent sleep apnea detection device as described above. Among them, the method includes:

[0037] After attaching the first cover plate to one side of the human nose bridge through the attaching film, adjust the angle of the second cover plate, and attach the second cover plate to the other side of the human nose bridge through the attaching film to complete the fixation, and then perform secondary binding fixation with the human head through the binding belt;

[0038] Detection begins. Each time exhalation or inhalation occurs, the airflow generated will drive the longer end foot of the detection piece to deflect. The shorter end foot of the detection piece will then deflect accordingly and amplify the output torque according to the lever principle. The shorter end foot of the detection piece acts on the piezoelectric film sensor, causing the piezoelectric film sensor to deform and generate an electrical signal. The wireless transmission chip receives the electrical signals generated by the two piezoelectric film sensors and sends them to an external detection host.

[0039] Applying the method of this application is not only lightweight and convenient. It eliminates the restraint of wires and can effectively ensure the reliability of wearing. It is not easy to shift or fall off during multiple turns during sleep. At the same time, a special detection piece is used to capture the breathing airflow. The torque generated by the breathing airflow is further amplified according to the lever principle. Then, the piezoelectric film sensor is used to convert the amplified torque into an electrical signal and output it to the processor chip for processing. After that, it is sent to an external detection host by the wireless transmission chip. It can collect the intensity data of each exhalation and each inhalation more accurately, providing the first-hand valuable breathing intensity data for the subsequent monitoring and protection data processing of sleep apnea hypopnea syndrome, and greatly improving the accuracy and precision of monitoring.
