Technical Field

The invention relates to a medical appliance, in particular to a nasal cavity support nasal septum fixer.

Background

The deviation of the nasal septum is called as deviation of the nasal septum when one or two sides of the nasal septum are bent or partially protruded to cause physiological dysfunction of nasal cavity and nasal sinuses and produce symptoms (such as nasal obstruction, epistaxis, headache, etc.). Good-onset people have a history of nasal trauma, adenoids are hypertrophic in childhood, family history, nasal polyps and tumor patients are diagnosed by general transnasal endoscopy, at present, surgical correction is the only treatment method for nasal septum deflection, after the nasal septum deflection is treated by surgery, the patients need to breathe by mouth rather than nose within 24 hours after the surgery, but the patients can breathe by nose within 24 hours after the surgery, but because the surgical wound part is in the nasal cavity, the nasal septum needs to be continuously fixed after the surgery 24 to repair the nasal septum wound part until the nasal septum wound part is repaired in order to prevent wound infection and damage the repaired nasal septum caused by external force.

The nose consists of three parts, namely an external nose, a nasal cavity and a nasal sinus.

(1) External nose: the external nose is the part of the nose that is visible on the outside, starting from the root of the ear between the eyebrows to the lower nose tip. The outer nasal cavities are respectively arranged on the left and the right below the nose tip, the wall separating the left nose cavity from the right nose cavity is the nasal septum, the part of the wall extending from the root to the center of the upper lip is in the middle of a person, the bulging parts on two sides of each outer nasal cavity are the nasal wings, the surface of each outer nose is covered by the skin, sweat glands are arranged in the thick skin of the nasal wings and the nose tip, so that the nose can sweat, and the nose tip part and the nasal septum are composed of cartilages and have elasticity, so that the nose is not easy to hurt even if being collided.

(2) Nasal cavity: the nasal cavity is a wide and complex cavity inside the external nostril, the cavity is narrowed again inside, the cavity opens to the pharynx through the holes of the left and right posterior nasal orifices, the nasal cavity is divided by the wall of the nasal septum in a left-right symmetrical manner, nasal concha and nasal passages protruding symmetrically from the side wall are arranged in the left and right nasal cavities, the nasal passages are passages for breathing air and flowing secretion, tears flowing out from eyes also flow into the lower nasal passage, the inner surface of the nasal cavity is covered by mucous membrane wetted by mucous membrane, a part with slightly changed color of the mucous membrane is arranged above the nasal cavity, and the part is an important part for feeling smell.

(3) Nasal sinuses: the paranasal sinuses are cavities surrounded by bones positioned outside the nasal cavity, 4 paranasal sinuses are respectively arranged at the left side and the right side in a symmetrical mode and are connected with the nasal cavity through fine passages, and mucous membranes of the nasal cavity extend to cover the inner surfaces of the cavities through the passages.

A large number of cells for sensing smell are distributed in the olfactory part above the nasal cavity, and smell molecules in air sucked in during respiratory movement can be sensed after contacting the olfactory cells. In addition, the trigeminal nerve widely distributed in ear mucosa also has the function of helping sense taste. When air sucked from the external nasal cavity passes through a narrow nasal cavity with a plurality of concave-convex parts, moisture of mucus secreted by mucous membranes can be fully absorbed, so that the temperature of the air is close to the body temperature, and the air is changed into humid air and then is sent into the lungs. In addition, dust in the air can be adsorbed on the nasal hair and mucus, thereby ensuring that clean air is delivered into the lungs. In addition, when the person is in the vocal, soft flap can free movement, and the partial air of exhaling gets into the nasal cavity and arouses the sympathetic response when the vocal to make sound louder.
