Description

Technical Field

[0001] The invention relates to the technical field of otolaryngology medical appliances, in particular to a bionic nasal concha. Background Art

[0002] The human nasal cavity starts from the nostril in front and ends at the posterior nostril in the back, communicating with the nasopharynx. The nasal cavity is divided into two cavities by the nasal septum, and each nasal cavity is divided into two parts: the nasal vestibule and the proper nasal cavity. The surface of the nasal vestibule is covered with skin, and the surface of the proper nasal cavity is covered with mucous membranes, which contain secretory glands and abundant blood vessels. The inferior turbinate in particular has a thicker mucous membrane covering its surface and abundant blood vessels under the mucosa, which can heat and humidify the inhaled air, thereby preventing the low-temperature, dry air from being directly inhaled into the lower respiratory tract and causing irritation and damage.

[0003] Excessive turbinate removal due to different reasons, or turbinate atrophy caused by certain diseases themselves, may cause a decrease in nasal resistance and weaken the nasal heating and humidification functions, thus causing "empty nose syndrome". "Empty nose syndrome" patients experience nasal congestion, dryness of the nasal cavity, nasopharynx and pharynx. Some patients experience a feeling of suffocation, inability to concentrate, fatigue, irritability, anxiety, depression, nasal purulent discharge, bloody secretions, foul odor, decreased sense of smell and other symptoms. The quality of life is significantly reduced, and some patients even commit suicide because of this.

[0004] At present, the main clinical treatment for "empty nose syndrome" is surgery, which is to implant a prosthesis to reduce the nasal cavity and improve symptoms. However, due to reasons such as rejection of the implanted material, the surgical effect is often not ideal, the surgery is expensive, and the patient needs to endure the pain of the surgery, so it cannot be promoted.

[0005] In view of this, how to enable patients with empty nose syndrome to humidify and warm the air inhaled into the nasal cavity while avoiding surgery has become a hot research topic for rhinologists this year. Summary of the invention

[0006] The purpose of the invention is to provide a bionic nose concha.

[0007] The present invention aims to solve the problem that the nasal resistance of patients with empty nose syndrome is reduced and the inhaled air is too low temperature and dry.

[0008] In order to solve the above problems, the present invention is implemented by the following technical solutions:

[0009] A bionic turbinate comprises a fixed section, a connecting section and a turbinate section which are connected in sequence. The turbinate section is placed in the inferior nasal meatus of a patient. The turbinate section comprises a frame and an inner core accommodated in the frame. The inner core is used to store physiological saline. The fixed section is placed in the nasal vestibule of the patient. The fixed section is provided with a through hole. The through hole is used for air circulation in the nasal cavity of the patient. The connecting section is connected between the turbinate section and the fixed section. The connecting section passes through the nasal valve of the patient.

[0010] Furthermore, the frame is a tubular strip adapted to the inferior nasal passage, and a plurality of through holes are arranged on the side wall of the frame.

[0011] Furthermore, a plurality of small columns are arranged on the inner wall of the frame toward the hollow center thereof.

[0012] Furthermore, the small columns are arranged in a spiral shape along the axial direction of the frame.

[0013] Furthermore, the cross section of the frame is quasi-circular, quasi-elliptical or C-shaped; wherein the shape of the inner core is adapted to the shape of the frame.

[0014] Furthermore, the side wall of the frame is provided with an opening along its axial direction.

[0015] Furthermore, the fixing section has an outline dimension that is larger than the inner diameter of the patient's nasal valve.

[0016] Furthermore, the fixing section is a circular ring, and the diameter of the circular ring is larger than the inner diameter of the patient's nasal valve.

[0017] Furthermore, the fixed section also includes a plurality of brackets, one end of which is connected to the circular ring and the other end of which is connected to the center of the circular ring.

[0018] Further, the connecting section includes at least one soft band connected between the fixing section and the nasal concha section.

[0019] Compared with the prior art, the technical solution of the present invention and its beneficial effects are as follows:

[0020] (1) The bionic turbinate of the present invention includes a fixed section, a connecting section and a turbinate section which are connected in sequence. The fixed section is placed in the patient's nasal vestibule; the connecting section passes through the patient's nasal valve, one end of which is connected to the fixed section in the nasal vestibule, and the other end is connected to the turbinate section of the inferior nasal meatus; the turbinate section is placed in the inferior nasal meatus to simulate the human turbinate. The turbinate section is fixed to the inferior nasal meatus by the fixed section to prevent it from slipping into the nasopharynx. The turbinate section includes a frame and an inner core in the frame. The inner core is wrapped in the frame to facilitate pushing the turbinate section into the inferior nasal meatus, and the inner core storing physiological saline humidifies the inhaled air, and the air passing through the bionic turbinate can also exchange heat with the bionic turbinate. The bionic turbinate achieves humidification and heating of the inhaled air, effectively improving a series of problems caused by empty nose syndrome.

[0021] (2) The small columns of the present invention are arranged in a spiral shape on the inner wall of the frame, and the small columns support a spiral channel between the frame and the inner core. The time for air to pass through the nasal concha section is greatly prolonged, so that the air has sufficient time to absorb moisture and exchange heat with the frame, thereby better heating and humidifying the air.

[0022] (3) The frame side wall of the present invention is provided with an opening along its axial direction. The setting of the opening makes it more convenient to replace the inner core, and allows the frame to hold more inner cores with different cross-sectional sizes, thereby changing the cross-sectional area of ​​the nasal concha segment, which is suitable for wearing by the same patient in different scenarios.

[0023] (4) The connecting section of the present invention includes two or three soft bands, so that the force between the fixing section and the nasal concha section is more balanced, thereby making it easier to pull out of the nasal cavity through the fixing section and the nasal concha section.

[0024] (5) The fixing section of the present invention is a circular ring, and a bracket is arranged on the circular ring. The bracket increases the stability of the circular ring, and when the bionic nose concha needs to be removed, there is more traction point when hooking the fixing section.

[0037] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] See also Figure 1 , a bionic turbinate, is used to be placed in the human nasal cavity to simulate the turbinate in the nasal cavity, so as to heat and humidify the air breathed into the nasal cavity, reducing the damage of low temperature and dry air to the throat and lungs.

[0040] It includes a fixed section 2, a connecting section 3 and a nasal concha section 1 which are connected in sequence. The fixed section 2 is placed in the patient's nasal vestibule; the connecting section 3 passes through the patient's nasal valve, one end of which is connected to the fixed section 2 in the nasal vestibule, and the other end is connected to the nasal concha section 1 of the inferior nasal meatus; the nasal concha section 1 is placed in the inferior nasal meatus to simulate the human nasal concha. The nasal concha section 1 is fixed to the inferior nasal meatus by the fixed section 2 to prevent the nasal concha section 1 from sliding into the nasopharynx. The outline size of the fixed section 2 is larger than the inner diameter of the patient's nasal valve, and the fixed section 2 is provided with a through hole, which is used for air circulation in the patient's nasal cavity to ensure smooth breathing of the patient. It can be understood that the fixed section 2 of the present invention adopts a fool-proof design, that is, the fixed section 2 cannot pass through the nasal valve from any direction, ensuring that the nasal concha section 1 connected to the fixed section 2 through the connecting section 3 will not slide down toward the nasopharynx, thereby causing foreign matter in the trachea.

[0041] In this embodiment, the fixing section 2 is a circular ring 20, whose diameter is larger than the inner diameter of the patient's nasal valve, so that the circular ring 20 moves only in the nasal vestibule section and does not pass through the nasal valve section, thereby preventing the turbinate section from sliding toward the nasopharynx. The connecting section 3 is a thin strip structure that passes through the patient's nasal valve without affecting nasal ventilation. In other embodiments, the fixing section can also be an ellipse, a semicircular ring, or the like, as long as the fixing section cannot pass through the patient's nasal valve.

[0042] See also Figure 2The turbinate segment includes a frame 10 and an inner core 13 in the frame. The inner core 13 is made of a water-absorbing material and is used to store physiological saline, so that the air breathed into the nasal cavity can be humidified. The frame 10 is a tubular strip adapted to the inferior nasal passage and is made of a soft material with a certain deformation ability, such as medical silicone, latex, etc., to improve the wearing comfort. The inner core 13 is placed in the hollow accommodating cavity of the frame 10. The frame 10 is provided with a plurality of through holes 11, which increases the contact area between the inner core 13 and the air entering the nasal cavity, so that the turbinate segment can more easily humidify the air.

[0043] The inner wall of the frame 10 is provided with a plurality of small columns 14 toward the hollow center thereof. The small columns 14 separate the frame 10 from the inner core 13. The air inhaled into the nasal cavity partially enters from one end of the turbinate segment 1, passes through the space between the inner core 13 and the inner wall of the frame 10, that is, the space supported by the small columns 14, passes through the surface of the inner core 13, and the water vapor of the inner core 13 humidifies the air passing through, and then flows out from the other end of the turbinate segment and enters the nasopharynx and lungs.

[0044] Embodiment 2

[0045] See also Figure 3 This embodiment is further improved on the basis of the first embodiment. In this embodiment, the small columns 14 are arranged in a spiral shape along the axial direction of the frame 10, that is, the small columns 14 support a spiral channel between the frame 10 and the inner core 13. Part of the air flows to the nasopharynx and lungs after passing through the spiral channel. The spiral channel greatly prolongs the time for the air to pass through the nasal concha segment, so that the air has sufficient time to absorb moisture and exchange heat with the frame, thereby better heating and humidifying the air. And the setting of the spiral channel allows the air to "turn" continuously, so that the inner core can well absorb the dust contained in the air.

[0046] Embodiment 3

[0047] See also Figures 4 to 6 This embodiment is further improved on the basis of the first or second embodiment. The cross-section of the frame 10 in this embodiment can be circular, elliptical or C-shaped, mainly to adapt to the shape of the nasal cavity and to be comfortable to wear. It can be understood that the shape of the inner core 13 is adapted to the shape of the frame 10.

[0048] An opening 12 is provided on the side wall of the frame 10, and the opening 12 is provided along the axial direction of the frame 10, that is, the cross section of the frame 10 is a non-closed ring. Opening the opening 12 facilitates the replacement of the inner core 13, and the size of the opening 12 changes the capacity of the frame 10, so that the frame 10 can place inner cores 13 with cross sections of different sizes, thereby changing the overall cross section of the nasal concha segment 1, that is, changing the size of the nasal concha segment 1. The same patient has different inhalation volumes in different states. For example, when running, the inhalation volume is large, so a bionic nasal concha with a smaller cross section is needed, while when resting, sleeping or cold, the breathing is slow, and a bionic nasal concha with a larger cross section is needed. The setting of the opening 12 makes it easy to adjust the size of the cross section of the bionic nasal concha to adapt to different scenarios.

[0049] Embodiment 4

[0050] See also Figure 7 This embodiment is further improved on the basis of the first embodiment, the second embodiment or the third embodiment. The connecting section 3 of this embodiment includes two soft belts. The two soft belts are symmetrically connected to the ring 20 and one end of the frame 10, so that when the ring 20 is hooked to pull the turbinate segment 1, the force of the turbinate segment 1 is balanced, and it is easier to pull the turbinate segment out of the nasal cavity smoothly. In other embodiments, the connecting section 3 can also be three soft belts, forming a triangular cone between the ring 20 and the frame 10. According to public knowledge, the triangle is the most stable, so the turbinate segment 1 can be well dragged out of the nasal cavity through the fixed section 2.

[0051] Embodiment 5

[0052] See also Figure 8 This embodiment is further improved on the basis of the first embodiment or the second embodiment or the third embodiment or the fourth embodiment. The fixed section 2 of this embodiment includes a ring 20 and a bracket 21 connected between the ring 20 and the center of the ring 20. The number of the brackets 21 is two or more. The bracket 21 improves the stability of the ring 20 and plays a certain supporting role for the ring 20. In addition, when it is necessary to remove the bionic turbinate, since the ring 20 sticks to the inner wall of the nasal vestibule, it is difficult to apply force whether it is hooked out by hand or other instruments, and it is easy to injure the mucosal layer of the inner wall of the nasal vestibule. The bracket 21 between the ring 20 and the center of the circle provides a good point of application for the medical hook or finger, which is convenient for removing the bionic turbinate.

[0053] The use of the bionic nasal concha of the present invention is as follows: apply medical lubricating oil on the surface of the nasal concha segment of the bionic nasal concha, gently push it into the nasal cavity, adjust the position so that the fixed section 2 is fixed to the nasal vestibule, the connecting section passes through the nasal valve, and the nasal concha segment is located in the inferior nasal meatus. Then, physiological saline is dripped into the nasal concha segment until the inner core is saturated with physiological saline. Then, the bionic nasal concha humidifies and heats the inhaled air. When the physiological saline in the inner core evaporates, physiological saline is dripped again. Hook the fixed section with your fingers or other instruments to take out the bionic nasal concha, which is convenient for disinfection of the bionic nasal concha and replacement of the inner core.

[0054] The bionic nasal concha of the present invention wraps the inner core in the frame, which is convenient for pushing the nasal concha segment into the inferior nasal meatus. The through holes and small columns are arranged on the frame, which greatly increase the contact area between the air and the inner core, so that the bionic nasal concha has a better humidification effect on the air. The setting of the fixed segment makes the nasal concha segment stably fixed in the inferior nasal meatus and easy to take out, which greatly increases the practical safety and convenience. The bionic nasal concha has a simple structure, is easy to use, can effectively solve a series of problems caused by empty nose syndrome, and is worthy of promotion.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention, through the above teachings or the technology or knowledge of the relevant field.
