Description

Nasal cavity hemostasis device

Technical Field

The utility model relates to a nasal cavity hemostasis device for hemostasis after nasal cavity blood vessel bleeds belongs to medical instrument technical field.

Background

Epistaxis is one of the common diseases in outpatient clinic, and is usually seen in spring and autumn, while some patients only have blood in nasal discharge, and some patients may cause hemorrhagic shock. The affected part can be any position of the nasal cavity, the easily bleeding area in the front part of the nasal cavity, namely the Li region, is mostly seen in teenagers and children, and the easily bleeding area in the back part of the nasal cavity is mostly seen in middle-aged and old people, namely the nose-nasopharynx venous plexus. The main point of diagnosing epistaxis is to clarify the etiology and the location of the bleeding point, wherein the etiology of epistaxis is complicated and can be roughly divided into two categories, namely local factors and systemic factors. The local factors include: trauma, tumors of nasal cavity, sinuses and nasopharynx, foreign bodies in nasal cavity, air pressure traumatic nasosinusitis and the like; systemic factors include: acute febrile infectious disease, heart and circulatory system diseases, hemorrhagic diseases, liver and kidney diseases, and rheumatic fever. The difference in causes of epistaxis can lead to different bleeding site locations, different bleeding volumes, for example: severe head and face trauma, and bleeding volume of patients who hurt maxillary artery, pre-and post-sift artery and sphenopalatine artery is large and severe, which often causes fatal rhinorrhagia; arterial hemorrhage caused by hypertension, arteriosclerosis, accompanied with hypertensive nephritis, eclampsia, etc., the hemorrhage part is usually the middle and rear section of nasal cavity or the top of nasal cavity, and the hemorrhage is bright red, fluctuating and can suddenly stop. Clinically, when a patient suddenly bleeds a lot at the nose, the patient often has no time to analyze the cause of disease, only can be treated according to the disease, and the bleeding is stopped first, so that serious consequences caused by large bleeding amount are avoided.

In the prior art, medical staff firstly use a front rhinoscope to observe whether bleeding points exist at the front parts of a nasal cavity and a nasal septum, then use the nasal scope to find the bleeding points at the rear part of the nasal cavity after the bleeding points can not be found by the front rhinoscope, enter nasopharynx parts and posterior nostril areas through a middle nasal passage, observe blood flow sources, find specific positions of the bleeding points, and finally use Vaseline yarn for filling or a hemostatic balloon for filling. However, in real-world situations, finding a bleeding point is very difficult and time-consuming, and if a patient continues to bleed a lot during the finding time, it is likely to cause hemorrhagic shock in the patient and serious panic in the family members of the patient.

Therefore, there is an urgent need for the researchers in this field to develop a nasal hemostat which can quickly determine the position of the bleeding point in the nasal cavity, effectively control the bleeding in time, and make the patient comfortable during the treatment period.
