Description

Technical Field

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

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

[0003] From an anatomical point of view, there are three parts above the larynx that are prone to stenosis and obstruction: the nose and nasopharynx, the oropharynx and soft palate, and the root of the tongue. There are also 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 and comprehensive research on obstructive sleep apnea and found that the disease is complex, changeable and ubiquitous. Therefore, obstructive sleep apnea cannot be generally regarded as an annoying sound that affects the rest of others in social life, but a clinical disease that needs to be carefully examined, which can cause many serious complications. Since the anatomical part of snoring is closely related to the ear, nose and throat, many patients often seek treatment from the otolaryngology department first.

[0004] In the prior art, when monitoring obstructive sleep apnea, nasal insertion and mask wearing are two common wearing methods. However, in actual use, although the nasal insertion type is compact and easy to wear, it needs to be inserted into the nasal cavity, and the patient may easily fall off due to discomfort or tossing during sleep, thereby affecting the continuity and accuracy of monitoring. Although the mask wearing type can cover the nose and mouth to ensure comprehensive monitoring of airflow, the wearing position and tightness of the mask are crucial to the accuracy of the airflow sensor. Improper wearing of the mask will cause the airflow sensor to be unable to accurately monitor changes in respiratory airflow, thereby 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

DETAILED DESCRIPTION

[0020] like Figures 1 to 4 As shown, a wearable obstructive sleep apnea warning device comprises a mask 1, an endotracheal connector 2, and two sets of fixing straps 3. The endotracheal connector 2 is connected to the mask 1 and is installed at the mask 1 near the nasal breathing position. The two sets of fixing straps 3 are respectively installed on both sides of the mask 1. A nasal rod 4 is arranged inside the mask 1 near the endotracheal connector 2, and two sets of airflow sensors 5 are installed on one end of the nasal rod 4; a rotating shaft 6 is arranged on the outer side of one end of the nasal rod 4 away from the airflow sensor 5, and a torsion assembly is arranged on the outer side of one end of the rotating shaft 6, and the torsion assembly comprises a first support rod 7, the first support rod 7 is fixedly connected to the mask 1, and one end of the first support rod 7 near the rotating shaft 6 is arranged in an open state, one end of the rotating shaft 6 extends to the inside of the opening of the first support rod 7 and is rotatably connected thereto, and the rotating shaft 6 is connected to the first support rod 7 through a first torsion spring 701.

[0021] In this embodiment, the mask 1 is covered on the nose of the monitored person's face in advance, and then the mask 1 is pressed by hand so that the mask 1 is translated close to the face. Since the initial position of the nasal rod 4 is set toward the face, the mask 1 is slightly moved close to the monitored person's face, and the nasal rod 4 and the airflow sensor 5 follow the mask 1 and move close to the monitored person's face. During the movement of the nasal rod 4, the nasal rod 4 is squeezed by the shape of the monitored person's face. The nasal rod 4 rotates a certain angle with the rotating shaft 6 as the axis to overcome the force of the first torsion spring 701 until the airflow sensor 5 is inserted into the two nasal cavities of the monitored person. After the airflow sensor 5 is inserted into the nasal cavity, the fixing strap 3 can be tied to the head of the monitored person and fixed; A first limiting assembly 8 is provided inside the opening of the first support rod 7, which is used to limit the rotation of the rotating shaft 6 to only one-way rotation. At the same time, when the airflow sensor 5 is inserted into the nasal cavity of the monitored person, the nasal rod 4 forms a fixed angle. Through the cooperation of the torsion assembly and the first limiting assembly 8, the airflow sensor 5 is quickly and accurately positioned. As a further solution of the present invention, the nasal rod 4 is composed of a group of U-shaped rods and a group of straight rods. The U-shaped rod is made of medical silicone material to avoid damaging the nasal cavity of the monitored person; two groups of airflow sensors 5 are respectively fixedly connected to the two ends of the U-shaped rod; the initial position of the U-shaped rod is that the two ends of the U-shaped rod are set in a direction away from the mask 1, and the two groups of airflow sensors 5 move synchronously with the nasal rod 4, and the two groups of airflow sensors 5 are respectively inserted into the two nasal cavities of the monitored person to perform airflow monitoring; 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 respiratory warning system. The respiratory warning system can detect the respiratory frequency and respiratory time data of the monitored person, and compare the respiratory frequency and respiratory time data with the normal respiratory data. If the data is abnormal, the abnormal information is directly transmitted to each monitoring device through the single-chip microcomputer connected to the abnormal breathing prompt module, thereby achieving the effect of intelligent early warning of the breathing of the monitored person. This is a prior art and will not be elaborated here.

[0022] like Figures 4 to 5 As shown, as a further solution of the present invention, the first limiting assembly 8 includes a ratchet 801, which is fixedly connected to the outer side of the rotating shaft 6, and a pawl 802 is provided on the top of the ratchet 801, and the inside of the pawl 802 is connected to a second support rod 804 through a second torsion spring 803; the second support rod 804 is fixedly connected to the inner wall of the first support rod 7.

[0023] In this embodiment, the nasal rod 4 is squeezed by the shape of the monitored person's face, and the nasal rod 4 rotates a certain angle with the rotating shaft 6 as the axis to overcome the force of the first torsion spring 701, and the rotating shaft 6 rotates with the nasal rod 4, and the rotation of the rotating shaft 6 drives the ratchet 801 to rotate. The ratchet 801 can only rotate in one direction under the limiting effect of the pawl 802, so the rotation direction of the nasal rod 4 is that the nasal rod 4 can only rotate in the direction away from the monitored person's face; Furthermore, one end of the pawl 802 is fixedly connected to a pull rope, one end of the pull rope passes through the first support rod 7 and slides therewith, and the end of the pull rope extending to the outside of the first support rod 7 is located inside the mask 1. After the monitoring of the person being tested is completed, the fixing strap 3 bound to the head of the person being tested can be untied, and the mask 1 can be removed. By pulling the pull rope, the pawl 802 overcomes the force of the second torsion spring 803 and rotates around the second support rod 804 as the axis. At this time, the ratchet 801 loses the limit of the pawl 802, so that the rotating shaft 6 is reset under the action of the first torsion spring 701.

[0024] Embodiment 2, as Figures 6 to 8 As shown, a groove 601 is formed 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.

[0025] As a further solution of the present invention: the driving mechanism 9 includes a sliding rod 901, one end of which 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 rod 4 is smaller than the cross-sectional width of the first sliding groove 401; both sides of the sliding rod 901 are respectively arranged in two groups of second sliding grooves 402 and slidably connected thereto, and a driving component is provided at the end of the sliding rod 901 away from the nasal rod 4.

[0026] In this embodiment, the sliding rod 901 is driven to move in the direction of the first sliding groove 401 by pressing the driving component. As a further solution of the present invention, the nasal rod 4 vertically penetrates the groove 601 and slides with it; the interior of the nasal rod 4 is provided with a first sliding groove 401 and two groups of symmetrically arranged second sliding grooves 402, and the second sliding grooves 402 are connected to the first sliding groove 401; the initial positions of the first sliding groove 401 and the second sliding groove 402 are set inside the groove 601, and the cross-sectional shape of the second sliding groove 402 is set to an arc shape, so that the sliding rod 901 moves horizontally along the axis of the rotating shaft 6 to drive the nasal rod 4 to move in the direction away from the nasal cavity, and the moving path of the nasal rod 4 is always moving on the axis directly opposite to the nasal cavity, and the airflow sensor 5 moves synchronously with the nasal rod 4, and the moving distance of the airflow sensor 5 is until the U-shaped rod contacts the outer wall of the rotating shaft 6 and stops.

[0027] As a further solution of the present invention: the driving 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 interior of the third support rod 903 is hollow, and the interior of the third support rod 903 is slidably connected to a slider 902 through a sealing ring. The setting of the sealing ring enables the interior of the mask 1 to remain sealed, and the end of the sliding rod 901 away from the nasal rod 4 is rotatably connected to the slider 902.

[0028] In this embodiment, the third support rod 903 and the first support rod 7 are respectively fixedly connected to the two symmetrical sides of the mask 1, and the slider 902 is pressed to drive the slider 901 to move, so as to drive the airflow sensor 5 to move in the direction away from the nasal cavity. The setting of the rotational 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 level 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, thereby improving the accuracy of data monitoring of the respiratory warning system.

[0029] like Fig. 9 As shown, as a further solution of the present invention, a second limiting assembly is provided on the side of the slider 902 away from the sliding rod 901; the second limiting assembly includes four groups of first teeth 904, and the four groups of first teeth 904 are fixedly connected to the inner wall of one end of the third support rod 903 away from the sliding rod 901; four groups of second teeth 905 meshing with the first teeth 904 are fixedly connected to the outer side of one end of the slider 902 away from the sliding rod 901, and the outer diameter of the end of the slider 902 away from the sliding rod 901 is smaller than the inner diameter of the third support rod 903, and the end of the slider 902 away from the sliding rod 901 is fixedly connected to a circular plate.

[0030] In this embodiment, the slider 902 is moved by pressing the circular plate, and the movement of the slider 902 drives the second teeth 905 to move. The first teeth 904 and the second teeth 905 are arranged in coordination to limit the position of the slider 902. At the same time, the four groups of first teeth 904 all protrude toward the inside of the third support rod 903 to limit the extraction position of the slider 902. Furthermore, the outer diameter of the circular plate is larger than the outer diameter of the third support rod 903, and the circular plate is arranged to limit the insertion position of the slider 902.
