Description
Technical Field
[0001] The utility model relates to the technical field of nasal cavity examination assistance, in particular to a nasal cavity examination assistance device. Background Art
[0002] The nasal cavity is a narrow, elongated cavity with a narrow top and a wide bottom. It begins at the anterior nostril and ends at the posterior nostril, communicating with the nasopharynx. It is divided into two chambers by the nasal septum, each consisting of the nasal vestibule and the proper nasal cavity. In higher vertebrates, this cavity is an arch-shaped cavity located between the base of the skull and the roof of the mouth. It is enclosed by bone and cartilage and lined with mucous membranes and skin. The nasal cavity is divided into two by a longitudinal nasal septum. Because the septum is often lopsided, the size and shape of the left and right nasal cavities are often asymmetrical. The nasal cavity communicates with the outside world anteriorly and posteriorly through the nostrils and with the nasopharynx, called the choanae. Each nasal cavity is further divided into the nasal vestibule and the proper nasal cavity. Nasal hairs filter inhaled air, reducing the inhalation of dust and other harmful substances. The nasal mucosa contains olfactory cells and secretory glands, as well as a rich supply of capillaries. Therefore, the nasal cavity warms and humidifies inhaled air.
[0003] Existing nasal examinations require a catheter or examination instrument to be inserted into the patient's nasal cavity during the examination. The skin inside the nasal cavity is relatively sensitive. After being touched, the patient may instinctively dodge with the entire head. The head lacks a fixed device, and when there is a sudden movement, the examination catheter has not yet been withdrawn from the nasal cavity, which may cause secondary damage to the mucosa inside the nasal cavity.
[0004] Therefore, in order to solve the above problems, a nasal cavity examination auxiliary device is proposed. Utility Model Content

The structure is simple and the operation is convenient.
[0028] like Figure 3 and Figure 4 As shown, a nasal examination auxiliary device, the head fixing component 1 is used to limit and fix the patient's head during the nasal examination, and the head fixing component 1 includes a U-shaped fixing frame 101, the inner wall of the U-shaped fixing frame 101 is fixedly connected to a support pillow 102, and the side of the U-shaped fixing frame 101 is threadedly connected to a fastening bolt 103, the end of the fastening bolt 103 is fixedly connected to a rotating block 104, and the outer part of the rotating block 104 is rotatably connected to a head fixing clamp 105, and the inner wall of the head fixing clamp 105 is fixedly connected to The protective cushion 106 and the fastening bolt 103 form a rotating structure through the rotating block 104 and the head fixing clamp 105, and the head fixing clamp 105 is arc-shaped, and there are two head fixing clamps 105 symmetrically arranged about the vertical central axis of the U-shaped fixing frame 101. The two head fixing clamps 105 cooperate with each other to limit and fix the patient's head from both sides, thereby limiting it during the process of nasal examination to prevent the patient from sudden movement due to instinctive reaction, and the instruments inside the nasal cavity from causing secondary damage to the nasal cavity.
[0029] like Figure 5As shown, a nasal examination auxiliary device, the angle adjustment component 3 is used to enable the head to be adjusted to an angle suitable for examination after being fixed, the angle adjustment component 3 includes a mounting seat 301, the bottom end of the mounting seat 301 is threadedly connected to a mounting bolt 302, and the top end of the mounting seat 301 is fixedly connected to an angle adjustment shaft 303, the outer rotation of the angle adjustment shaft 303 is connected to an angle adjustment cylinder 304, and the outer wall of the angle adjustment cylinder 304 is fixedly connected to a spring 305, the end of the spring 305 is fixedly connected to a limit pin 306, and the end of the limit pin 306 is engaged with a limit hole 307, and the limit pin 306 is connected to the angle adjustment cylinder 304 through the spring 305.
