Nasal bleeding is one of the common diseases in outpatient clinics, and more in spring and autumn, the lighter one is only nasal discharge with blood, and the heavier one can cause hemorrhagic shock. The affected part can be any position of the nasal cavity, and most of teenagers and children are regions with easy bleeding at the front part of the nasal cavity, namely Li Shi regions, while the middle-aged and the elderly people are mainly concentrated at the rear part of the nasal cavity, namely the nasal-nasopharynx venous plexus. The focus of nasal bleeding diagnosis is to clarify the etiology and location of bleeding points, where the etiology of nasal bleeding is complex and can be broadly divided into two major categories, namely local and systemic factors. Local factors include trauma, nasal cavity, nasal sinus, nasopharyngeal tumor, nasal foreign body, barotrauma sinusitis, etc., systemic factors include acute febrile infectious disease, heart and circulatory system diseases, hemorrhagic diseases, liver and kidney diseases, wind damp heat, etc. The different causes of the epistaxis can lead to different bleeding points and different bleeding amounts, such as serious head and face trauma, excessive and severe bleeding of the maxillary artery, the pre-and post-sieve artery and the sphenopalatine artery, often causes fatal epistaxis, arterial bleeding caused by diseases such as hypertension, arteriosclerosis, nephritis with hypertension, eclampsia and the like, and bleeding parts are often in the middle and rear sections of the nasal cavity or the top of the nasal cavity, and bleeding is bright red, wavy and can suddenly stop. Clinically, when a patient suddenly bleeds from the nose, the patient often cannot analyze the etiology and can only treat the disease, and the patient stops bleeding first, so that serious consequences caused by the large bleeding amount are avoided.
In the prior art, medical staff firstly observe whether bleeding points exist in the front parts of the nasal cavities and nasal septa by using a front nasal scope, after the bleeding points cannot be found by using the front nasal scope, then find the bleeding points in the rear parts of the nasal cavities by using a nose endoscope, enter the nasopharynx part and the rear nostril area through the middle nasal passage, observe blood flow sources, find specific positions of the bleeding points, and finally fill the bleeding points by using Vaseline yarns or blood cell stopping bags. In reality, however, it is very difficult and time consuming to locate bleeding points, and if the patient continues to bleed a lot during the search time, it is likely to cause hemorrhagic shock in the patient and serious panic in the patient's family.
Accordingly, there is a great need in the art for developing a nasal hemostatic device that can quickly determine the location of a nasal hemorrhage site, and that is effective in controlling nasal hemorrhage, and that allows a patient to wear a comfortable nasal hemostatic device during treatment.

The weak connection part 3 is ring-shaped, is a medical adhesive arranged between the outer surface of a section of support main body 1 and the inner surface of the air bag 2, the weak connection part 3 has certain adhesive strength, the air bag 2 and the support main body 1 are adhered together, the air bag 2 is divided into two parts after being adhered, the first air bag 21 and the second air bag 22 are divided, the air outlet 11b is positioned in the first air bag 21, when the air passage 11 is used for inflating the air bag 2, the air bag 21 is inflated firstly, the first air bag 21 is inflated continuously, the adhesion between the air bag 2 and the support main body 1 is broken, the weak connection part 3 releases the separation of the air bag 2, the second air bag 22 is inflated after the first air bag 21 is inflated, so that the first air bag 21 and the second air bag 22 are inflated sequentially from the deep of the nasal cavity to the nostril direction, if the bleeding position is positioned at the deep of the nasal cavity, the bleeding is controlled after the inflation of the first air bag 21, and if the bleeding position is positioned at the position close to the nostril, the inflation of the second air bag 22 is required to be inflated for hemostasis.
A third embodiment of the nasal hemostatic device provided by the present invention is described below.
Referring to fig. 7, a third embodiment of the nasal cavity hemostatic device provided by the present invention has substantially the same structure as the first embodiment, and differs therefrom in that:
The weak connection part 3 is a magnetic ring buried in the pipe wall of the supporting main body 1 and the inner wall of the air bag 2, the weak connection part 3 positioned in the supporting main body 1 is opposite to the weak connection part 3 positioned in the air bag 2, the weak connection part 3 is annular and made of magnetic materials, the air bag 2 is connected with the supporting main body 1 in an sucking way, the air bag 2 is divided into two parts after being connected and divided into a first air bag 21 and a second air bag 22, the air outlet 11b is positioned in the first air bag 21, when the air passage 11 is used for inflating the air bag 2, the first air bag 21 is inflated firstly, the first air bag 21 is inflated continuously, the sucking way between the air bag 2 and the supporting main body 1 is broken, the weak connection part 3 releases the separation of the air bag 2, the second air bag 22 is inflated after the first air bag 21 is inflated, thus the first air bag 21 and the second air bag 22 are inflated sequentially from the deep in the nasal cavity direction, if a bleeding position is positioned in the deep, the bleeding position is controlled after the inflation of the first air bag 21, and if the bleeding position is positioned near the nostril, the second air bag 22 is inflated, the inflation is needed for stopping bleeding.
A fourth embodiment of the nasal hemostatic device provided by the present invention is described below.
Referring to fig. 8, a fourth embodiment of the nasal hemostatic device provided by the present invention has substantially the same structure as the first embodiment, and differs therefrom in that:
The weak connection part 3 is ring-shaped, is a film coated on the outer surface of the air bag 2, is provided with a tearing line, when the film is torn along the tearing line under the action of external force, the air bag 2 and the supporting main body 1 are bound together by the weak connection part 3, the air bag 2 is divided into two parts after being bound and divided into a first air bag 21 and a second air bag 22, the air outlet 11b is positioned in the first air bag 21, when the air passage 11 is used for inflating the air bag 2, the air bag 21 is inflated firstly, the air bag 21 is inflated continuously, the weak connection part 3 is torn, the separation of the air bag 2 is released by the weak connection part 3, the second air bag 22 is inflated and inflated after the air bag 21 is inflated, so that the first air bag 21 and the second air bag 22 are inflated sequentially from the deep of the nasal cavity to the nostril direction, if the bleeding position is positioned at the deep of the nasal cavity, the bleeding is controlled after the air inflation of the first air bag 21, and if the bleeding position is positioned at the position close to the nostril, the air bag 22 is inflated and inflated to stop bleeding.
