Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a wearable obstructive sleep apnea warning device. Background Art

[0002] Obstructive sleep apnea generally refers to the situation where an adult has more than 30 episodes during 7 hours of sleep per night. During each episode, the airflow through the mouth and nose stops for 10 seconds or longer, accompanied by symptoms such as a decrease in blood oxygen saturation. When breathing normally, the key to gas exchange is the upper respiratory tract above the larynx, which allows air to smoothly enter the trachea and bronchi. If the airflow in this section is blocked for some reason, symptoms such as snoring or obstructive sleep apnea will occur.

[0003] From an anatomical perspective, there are three parts above the larynx that are prone to stenosis and obstruction, namely: the nose and nasopharynx, the oropharynx and soft palate, and the root of the tongue. In addition, there are central sleep apnea (CSA) and mixed sleep apnea (MSA). In recent years, with the continuous progress of various testing methods, people have continuously conducted in-depth comprehensive research on obstructive sleep apnea and found the complexity, variability, and prevalence of this disease. Therefore, obstructive sleep apnea should not be generally regarded as an annoying sound that affects the rest of others in social life, but rather a clinical disorder that requires careful examination, as it can cause many serious complications. Since the anatomical location where snoring occurs is closely related to otolaryngology, many patients often seek treatment from the otolaryngology department first.

[0004] In the prior art, when monitoring obstructive sleep apnea, nasal insertion type and mask wearing type are two common wearing methods. However, in the actual application process, although the nasal insertion type is small and convenient to wear, since it needs to be inserted into the nasal cavity, patients are prone to make it fall off due to discomfort or turning during sleep, thus affecting the continuity and accuracy of monitoring. Although the mask wearing type can cover the nose and mouth to ensure comprehensive monitoring of the airflow, the wearing position and tightness of the mask are crucial for the accuracy of the airflow sensor. If the mask is worn improperly, the airflow sensor cannot accurately monitor the changes in the respiratory airflow, reducing the accuracy of the monitoring data.

[0005] Therefore, it is necessary to provide a wearable obstructive sleep apnea warning device to solve the above technical problems. Summary of the Invention

[0006] The object of the present invention is to provide a wearable obstructive sleep apnea warning device to solve the defects of the prior art proposed in the above background art. Although the nasal insertion type is small and convenient to wear, since it needs to be inserted into the nasal cavity, patients are prone to make it fall off due to discomfort or turning during sleep, thus affecting the continuity and accuracy of monitoring. Although the mask wearing type can cover the nose and mouth to ensure comprehensive monitoring of air flow, the wearing position and tightness of the mask are crucial for the accuracy of the air flow sensor. Improper wearing of the mask causes the air flow sensor to be unable to accurately monitor the changes in respiratory air flow, reducing the accuracy of monitoring data and other problems.

Through the cooperation of the torsion assembly and the first limiting assembly, the air flow sensors are accurately positioned.

[0008] As a further solution of the present invention: the nasal rod is composed of a U-shaped rod and a straight rod. The U-shaped rod is made of medical silicone material. The two air flow sensors are respectively fixedly connected to both ends of the U-shaped rod. The initial position of the U-shaped rod is that both ends of the U-shaped rod are arranged in a direction away from the mask.

A pawl is arranged on the top of the ratchet wheel. The inside of the pawl is connected to a second support rod through a second torsion spring. The second support rod is fixedly connected to the inner wall of the first support rod.

[0010] As a further solution of the present invention: a groove is opened at the end of the rotating shaft away from the first limiting assembly. A driving mechanism is arranged inside the groove for adjusting the distance between the air flow sensor and the nostril.

[0011] As a further solution of the present invention: the nasal cavity rod vertically penetrates through the groove and is in sliding fit with it; a first sliding groove and two symmetrically arranged second sliding grooves are formed inside the nasal cavity rod, and the second sliding groove communicates with the first sliding groove; the initial positions of the first sliding groove and the second sliding groove are arranged inside the groove.

[0012] As a further solution of the present invention: the driving mechanism includes a sliding rod, one end of the sliding rod is arranged inside the first sliding groove, and the cross-sectional width of the end of the sliding rod close to the nasal cavity rod is smaller than the cross-sectional width of the first sliding groove; both sides of the sliding rod are respectively arranged in the two second sliding grooves and are in sliding connection with them, and a driving component is arranged at the end of the sliding rod away from the nasal cavity rod.

[0013] As a further solution of the present invention: the driving component includes a third support rod, the third support rod is fixedly connected to the mask, and one end of the third support rod extends to the outside of the mask; the inside of the third support rod is hollow, and a slider is slidably connected to the inside of the third support rod through a sealing ring, and the end of the sliding rod away from the nasal cavity rod is rotatably connected to the slider.

[0014] As a further solution of the present invention: a second limiting component is arranged on the side of the slider away from the sliding rod; the second limiting component includes four first teeth, and the four first teeth are all fixedly connected to the inner wall of the end of the third support rod away from the sliding rod; four second teeth meshing with the first teeth are fixedly connected to the outside of the end of the slider away from the sliding rod, and the outer diameter of the end of the slider away from the sliding rod is smaller than the inner diameter of the third support rod; a circular plate is fixedly connected to the end of the slider away from the sliding rod, and the outer diameter of the circular plate is larger than the outer diameter of the third support rod.

Detailed implementation manners

[0028] As Figures 1 to 4As shown in the figure, a wearable obstructive sleep apnea warning device includes a face mask 1, a tracheal connector 2, and two groups of fixing straps 3. The tracheal connector 2 is connected to the face mask 1 and installed near the nasal breath position of the face mask 1. The two groups of fixing straps 3 are respectively installed on both sides of the face mask 1. A nasal cavity rod 4 is arranged inside the face mask 1 near the tracheal connector 2, and two air flow sensors 5 are installed at one end of the nasal cavity rod 4; a rotating shaft 6 is arranged outside one end of the nasal cavity rod 4 away from the air flow sensors 5, and a torsion assembly is arranged outside one end of the rotating shaft 6. The torsion assembly includes a first support rod 7, and the first support rod 7 is fixedly connected to the face mask 1. One end of the first support rod 7 near the rotating shaft 6 is in an open state. One end of the rotating shaft 6 extends into the opening of the first support rod 7 and is rotatably connected thereto. The rotating shaft 6 is connected to the first support rod 7 through a first torsion spring 701.

[0029] In this embodiment, first cover the face mask 1 on the nose of the person to be monitored. Immediately press the face mask 1 by hand so that the face mask 1 moves horizontally against the face. Since the initial position of the nasal cavity rod 4 is set towards the face, slightly move the face mask 1 against the face of the person to be monitored. The nasal cavity rod 4 and the air flow sensors 5 move closely against the face of the person to be monitored following the face mask 1. During the movement of the nasal cavity rod 4, the nasal cavity rod 4 is squeezed by the shape of the face of the person to be monitored. The nasal cavity rod 4 rotates a certain angle around the rotating shaft 6 against the acting force of the first torsion spring 701 until the air flow sensors 5 are inserted into the two nasal cavities of the person to be monitored. After the air flow sensors 5 are inserted into the nasal cavities, the fixing straps 3 can be bound to the head of the person to be detected for fixation;

[0030] A first limiting component 8 is arranged inside the opening of the first support rod 7 to limit the one-way rotation of the rotating shaft 6. At the same time, when the air flow sensors 5 are inserted into the nasal cavities of the person to be monitored, the nasal cavity rod 4 forms a fixed angle. Through the cooperation of the torsion assembly and the first limiting component 8, the air flow sensors 5 can be quickly and accurately positioned. As a further solution of the present invention, the nasal cavity rod 4 is composed of a U-shaped rod and a straight rod. The U-shaped rod is made of medical silicone material to avoid damaging the nasal cavities of the person to be monitored; the two air flow sensors 5 are respectively fixedly connected to both ends of the U-shaped rod; the initial position of the U-shaped rod is that both ends of the U-shaped rod are arranged towards the direction away from the face mask 1. The two air flow sensors 5 move synchronously with the nasal cavity rod 4, and the two air flow sensors 5 are respectively inserted into the two nasal cavities of the person to be monitored for air flow monitoring;

[0031] The output end of the airflow sensor 5 is electrically connected to the input end of the information interaction module, and the output end of the information interaction module is electrically connected to the input end of the breathing warning system. The breathing warning system can detect the breathing frequency and breathing time data of the monitored person, and compare the breathing frequency and breathing time data with the normal breathing data. If the data is abnormal, the abnormal information will be directly transmitted to each monitoring device through the single-chip microcomputer connected to the breathing abnormality prompt module, so as to achieve the effect of intelligent warning of the breathing of the monitored person. This is the prior art and will not be elaborated here.

[0032] As Figures 4 to 5 shown, as a further solution of the present invention, the first limiting component 8 includes a ratchet wheel 801, the ratchet wheel 801 is fixedly connected to the outside of the rotating shaft 6, a pawl 802 is arranged on the top of the ratchet wheel 801, and a second support rod 804 is connected to the inside of the pawl 802 through a second torsion spring 803; the second support rod 804 is fixedly connected to the inner wall of the first support rod 7.

[0033] In this embodiment, the nasal cavity rod 4 is squeezed by the facial shape of the monitored person. The nasal cavity rod 4 rotates a certain angle around the rotating shaft 6 against the acting force of the first torsion spring 701. The rotating shaft 6 follows the rotation of the nasal cavity rod 4. The rotation of the rotating shaft 6 drives the ratchet wheel 801 to rotate. Under the limiting action of the pawl 802, the ratchet wheel 801 can only rotate in one direction. Therefore, the rotation direction of the nasal cavity rod 4 is that the nasal cavity rod 4 can only rotate in the direction away from the face of the monitored person;

[0034] Further, one end of the pawl 802 is fixedly connected with a pull rope. One end of the pull rope passes through the first support rod 7 and slides with it, and the end of the pull rope extending outside the first support rod 7 is located inside the mask 1. After the detection of the detected person is completed, the fixing strap 3 bound to the head of the detected person can be untied, the mask 1 can be taken off, and the pawl 802 can be pulled by pulling the pull rope to rotate around the second support rod 804 against the acting force of the second torsion spring 803. At this time, the ratchet wheel 801 loses the limit of the pawl 802, so that the rotating shaft 6 is reset under the acting force of the first torsion spring 701.

[0035] Embodiment 2, as Figures 6 to 8 shown, a groove 601 is opened at one end of the rotating shaft 6 away from the first limiting component 8, and a driving mechanism 9 is arranged inside the groove 601 for adjusting the distance between the airflow sensor 5 and the nostril.

[0036] As a further solution of the present invention: the driving mechanism 9 includes a sliding rod 901. One end of the sliding rod 901 is arranged inside the first sliding groove 401, and the cross-sectional width of the end of the sliding rod 901 close to the nasal cavity rod 4 is smaller than the cross-sectional width of the first sliding groove 401; both sides of the sliding rod 901 are arranged in two groups of second sliding grooves 402 and slide with them, and a driving component is arranged at the end of the sliding rod 901 away from the nasal cavity rod 4.

[0037] In this embodiment, the slider 901 is driven by the pressing drive assembly to move in the direction of the first chute 401. As a further solution of the present invention, the nasal cavity rod 4 vertically penetrates through the groove 601 and is in sliding fit therewith; a first chute 401 and two symmetrically arranged second chutes 402 are provided inside the nasal cavity rod 4, and the second chute 402 is communicated with the first chute 401; the initial positions of the first chute 401 and the second chute 402 are arranged inside the groove 601. At the same time, the cross-sectional shape of the second chute 402 is set to be arc-shaped. Therefore, the slider 901 moves horizontally along the axis of the rotating shaft 6 to drive the nasal cavity rod 4 to move away from the nasal cavity. The moving path of the nasal cavity rod 4 is always on the axis directly facing the nasal cavity. At the same time, the airflow sensor 5 moves synchronously with the nasal cavity rod 4. The moving distance of the airflow sensor 5 is until the U-shaped rod contacts the outer wall of the rotating shaft 6 and then stops.

[0038] As a further solution of the present invention: the drive assembly includes a third support rod 903. The third support rod 903 is fixedly connected to the mask 1, and one end of the third support rod 903 extends to the outside of the mask 1; the inside of the third support rod 903 is hollow, and a slider 902 is slidably connected to the inside of the third support rod 903 through a sealing ring. The setting of the sealing ring enables the inside of the mask 1 to maintain a seal. One end of the slider 901 away from the nasal cavity rod 4 is rotatably connected to the slider 902.

[0039] In this embodiment, the third support rod 903 and the first support rod 7 are respectively fixedly connected to two symmetric sides of the mask 1. Pressing the slider 902 drives the slider 901 to move, which is used to drive the airflow sensor 5 to move away from the nasal cavity. The rotatable connection between the slider 901 and the slider 902 can not only quickly and accurately insert the airflow sensor 5 into the nasal cavity, but also further adjust the distance between the airflow sensor 5 and the nasal cavity. While improving the comfort of the monitored person, it can also ensure that the distance between the nasal cavity of patients with different facial features and the airflow sensor 5 is the same, improving the accuracy of data monitoring of the breathing warning system.

[0040] As Figure 9 shown, as a further solution of the present invention, a second limiting component is provided on the side of the slider 902 away from the slider 901; the second limiting component includes four groups of first teeth 904, and the four groups of first teeth 904 are all fixedly connected to the inner wall of one end of the third support rod 903 away from the slider 901; four groups of second teeth 905 meshing with the first teeth 904 are fixedly connected to the outside of one end of the slider 902 away from the slider 901, and the outer diameter of one end of the slider 902 away from the slider 901 is smaller than the inner diameter of the third support rod 903. A round plate is fixedly connected to one end of the slider 902 away from the slider 901.

[0041] In this embodiment, pressing the circular plate drives the slider 902 to move. The movement of the slider 902 drives the movement of the second tooth 905. Through the cooperative arrangement of the first tooth 904 and the second tooth 905, the position of the slider 902 is limited. At the same time, all four groups of the first teeth 904 protrude towards the inside of the third support rod 903 to limit the pulling-out position of the slider 902. Further, the outer diameter of the circular plate is larger than the outer diameter of the third support rod 903, and the circular plate is provided to limit the insertion position of the slider 902.

[0042] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only used to illustrate the principles of the present invention.
