[0001] The invention relates to the technical field of medical devices, and in particular to a nasopharyngeal endoscope fixing device for real-time monitoring of upper airway obstruction. Background Art

[0002] Obstructive sleep apnea-hypopnea syndrome (OSAHS) is one of the common and frequently occurring diseases in the clinical practice of otolaryngology. It is caused by the narrowing, collapse and closure of the upper airway in the throat due to pathological or body position reasons during sleep, which leads to respiratory obstruction, apnea, and hypoxia, resulting in a series of symptoms, signs and pathological changes. It is one of the important causes of diseases of the cardiovascular and cerebrovascular systems, respiratory systems, endocrine systems, neuropsychiatric systems, sexual dysfunction, etc. Since the anatomical position of the throat is located deep in the middle and lower part of the head and neck, it is relatively hidden and sensitive, so it is particularly difficult to check during sleep.

[0003] At present, the examination of this disease is limited to the peripheral index examination of polysomnography, such as electroencephalogram, electrocardiogram, respiratory movement, blood oxygen saturation, body position, and drug-induced sleep fiber laryngoscopy. Since the peripheral index examination cannot truly reflect the upper airway collapse of OSAHS, the drug-induced sleep fiber laryngoscopy is limited to the induction of anesthetic drugs, body position restrictions and short examination time, and cannot truly reflect the continuous state of upper airway collapse of OSAHS within a few hours. So far, there is no effective examination method at home and abroad that can truly reflect the upper airway obstruction of OSAHS. Summary of the invention

The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0024] Examples, such as Figures 1 to 6As shown, the present invention discloses an endoscope fixing device installed in the nasopharynx, including a millimeter-level micro camera 1, a nasal septum fixing bracket 2, a connecting wire 3 and a data receiver module 4, wherein the connecting wire 3 includes two wires including a data transmission line and a power line, and the data receiver module 4 also includes a battery, and the battery is used to power the entire device, and the battery supplies power to the millimeter-level micro camera 1 through the power line, and the nasal septum fixing bracket 2 includes a rear bracket 201 and a front bracket 202, and the millimeter-level micro camera 1 is fixedly arranged in the rear bracket 201.

[0025] An observation port is provided on the rear bracket 201, and the millimeter-level micro camera 1 observes the situation of the throat from the observation port. The direction of the observation port is perpendicular to the axial direction of the rear bracket. The nasal septum fixing bracket 2 is clamped at the nasal septum position to fix the millimeter-level micro camera 1. The rear bracket 201 is slidably connected to the front bracket 202, so that the length of the entire nasal septum fixing bracket 2 can be adjusted. The data receiver module 4 is electrically connected to the millimeter-level micro camera 1 through a connecting wire 3.

[0026] Furthermore, a transparent sheet 5 is fixedly provided at the observation port, and the transparent sheet 5 is used to provide waterproof protection for the millimeter-level micro camera 1 in the 202. At the same time, the transparent sheet 5 is also used to provide a clear observation environment for the millimeter-level micro camera 1.

[0027] When in use, the entire nasal septum fixing bracket 2 is fixed at the nasal septum position by the front bracket 202, and the rear bracket 201 is slidably connected to the front bracket 202. The length of the rear bracket 201 extending into the nasal cavity can be adjusted by stretching the rear bracket 201. A millimeter-level micro camera 1 is fixed in the rear bracket 201, and the real-time situation of the throat is observed by the millimeter-level micro camera 1. The position observed by the millimeter-level micro camera 1 is the throat below the nasopharynx.

[0028] It should be noted that the nasal septum fixing bracket 2 is made of medical silicone material as a whole. Medical silicone has good compatibility with human tissue, can effectively avoid the rejection reaction of the human body, and can be stored in the human cavity structure for a long time.

[0029] Furthermore, the front bracket 202 and the rear bracket 201 are the main parts of the nasal septum fixing bracket 2. When in use, the main part extends into the nasal cavity. The front bracket 202 is also provided with a sub-bracket 2022, and the sub-bracket 2022 is also elliptical. The sub-bracket 2022 is a bending feature on the front bracket 202. The overall Shore hardness of the front bracket 202 is 80A. The sub-bracket 2022 cooperates with the main part of the front bracket 202, and the sub-bracket 2022 and the main part of the front bracket 202 extend into two different nasal cavities respectively. The position of the nasal septum is clamped by the cooperation between the sub-bracket 2022 and the main part of the front bracket 202. , so that the entire device can be completely installed and fixed in the nasal cavity.

The connecting wire 3 passes through the threading hole 2021 into the rear bracket 201 and is electrically connected to the millimeter-level micro camera 1. When in use, ensure that the observation port on the rear bracket 201 is facing downward, extend the main body of the rear bracket 201 and the front bracket 202 into the nasal cavity on one side, and then insert the sub-bracket 2022 into the nasal cavity on the other side, thereby clamping on both sides of the nasal septum, completing the fixation of the nasal septum fixing bracket 2 as a whole in the nasal cavity, and finally the millimeter-level micro camera 1 can observe the throat at a fixed position in the nasopharyngeal cavity.

[0030] In this embodiment, the front bracket 202 and the rear bracket 201 are both elliptical, the diameter of the front bracket 202 is smaller than that of the rear bracket 201, the major diameter of the front bracket 202 is in the range of 3-4 mm, the wall thickness is 1 mm, the inner diameter is in the range of 1-2 mm, and the length is 40-60 mm. In this embodiment, 50 mm is preferably used. The major diameter of the rear bracket 201 is in the range of 5-6 mm, the inner diameter of the rear bracket 201 is in the range of 3-4 mm, the wall thickness of the rear bracket 201 is 1 mm, the length is 40-65 mm, and 55 mm is preferably used.

The spacing between the auxiliary bracket 2022 and the main body of the front bracket 202 is in the range of 3-8 mm, and 5 mm is preferably used in this spacing range.

[0031] Advantageously, on the rear bracket 201, a light source is provided in the transparent sheet 5, and LED lamp beads 6 are provided in the transparent sheet 5. The LED lamp beads 6 are fixed to the millimeter-level micro camera 1, and the LED lamp beads 6 are also powered by the connecting wires 3. The light source is provided by the LED lamp beads 6, and the light source is used to provide a bright observation environment for the millimeter-level micro camera 1.

[0032] In this embodiment, the connecting wire 3 serves as both the image data connecting wire 3 of the millimeter-level micro camera 1 and the power supply line of the millimeter-level micro camera 1. A data storage module is also provided in the data receiver module 4. The image data observed by the millimeter-level micro camera 1 is stored through the data storage module to facilitate subsequent reading of the image. When the wearer wears it, the data receiver module 4 can be fixed on the user's head through a headband.
