Description
Technical field
The present invention relates to a kind of nasal cavity haemostats to belong to medical device technology for the hemostasis after nasal cavity angiorrbagia
Field.
Background technique
Nosebleed is one of outpatient service common disease, and spring and autumn, hair patient was more, and less serious case is only band blood in tears, and severe one can cause blood loss
Shock.Site of pathological change can be any position of nasal cavity, be mostly the easy bleeding area in nasal cavity front, i.e. Li Shi in teenager and children
Area, and person in middle and old age are concentrated mainly on nasal cavity rear portion, mostly woodruff's plexus.The emphasis of nosebleed diagnosis is to understand the cause of disease
With the position of blutpunkte, wherein the cause of disease of nosebleed is complex, is broadly divided into two major classes, i.e., local factor and whole body because
Element.Local factor includes: wound, the tumour of nasal cavity, nasal sinus, nasopharynx, nasal foreign body, barotraumatic sinusitis etc.；Whole body because
Element includes: febris acuta sexually transmitted disease, heart and circulation system disease, hemorrhagic disease, liver and kidney disease and rheumatic fever etc..Nose goes out
The difference of the blood cause of disease will lead to the difference of blutpunkte position, the difference of amount of bleeding, such as: serious Head And Face wound injures
Before jaw artery, sieve and posterior ethmoidal artery, sphenopalatine artery person amount of bleeding are more and violent, often cause lethal nosebleed；Hypertension is moved
Arterial hemorrhage caused by the diseases such as arteries and veins hardening, accompanied with hypertension ephritis, eclampsia, bleeding part is often posterior segment or the nasal cavity of nasal cavity
Top, bleeding is cerise, fluctuation, can happen suddenly hang-up.Clinically, when the unexpected nose of patient is bled profusely, usually have little time
The cause of disease is analyzed, can only suit the medicine to the illness and treat, first stop blooding, avoid leading to grave consequences greatly because of amount of bleeding.
In the prior art, whether medical staff has blutpunkte first with prenasal sem observation nasal cavity, nasal septum front, in prenasal
After mirror can not find blutpunkte, recycles nasal endoscopes to find the blutpunkte at nasal cavity rear portion, enters pharynx nasalis, region choanarum through middle nasal meatus,
Blood flow source is observed, blutpunkte specific location is searched, finally utilizes vaseline gauze filling or the Balloon tamponade that stops blooding.But real feelings
In condition, it is very difficult and time consuming for searching blutpunkte, if persistently bled profusely searching patient in the time, it is likely that cause
The serious threat of patient's haemorrhagic shock and family numbers of patients.
Therefore, this field research staff urgent need, which researches and develops one kind, can judge rapidly nasal bleeding point position, timely and effective control
Nasal bleeding processed, and make the nasal cavity haemostat of patient's comfortable wearing during treatment.
Summary of the invention
Nasal bleeding point position can be judged rapidly the present invention provides one kind, timely and effective control nasal bleeding, and
