Abstract
A nasal cavity airbag dilation catheter, which belongs to the field of medical instruments, comprises a double-cavity catheter, a main cavity, an inflatable base, a switch valve, an auxiliary cavity and an airbag, wherein, the airbag is arranged at a position away from the top of the double-cavity catheter by 5 cm and is connected with the double-cavity catheter as a whole. The airbag with a three-layered composite structure comprises, from outside to inside, an outer adhesive layer, a fiber layer and an inner adhesive layer, wherein, the inner adhesive layer can ensure rapid expansion of the airbag during aeration; the outer adhesive layer can ensure shrinkage of the airbag during deflation; and the fiber layer can ensure that the diameter of the airbag can not be increased optionally while increasing pressure in the airbag. The double-cavity catheter includes the main cavity and the auxiliary cavity, wherein, the main cavity is a through-cavity; the inflatable base is arranged on the rear end of the double-cavity catheter; the switch valve is arranged on one side of the inflatable base; and the auxiliary cavity starts from the inflatable base, and the head opening is arranged in the airbag. The nasal cavity airbag dilation catheter has the advantages of reasonable structure, reliable performance, low cost and good popularization value.
Description
Technical field
This utility model relates to the medical apparatus and instruments auxiliary device, treats a kind of nasal cavity balloon dilatation catheter of rhinitis, sinusitis specifically.
Background technology
Rhinitis, sinusitis be clinical in a kind of commonly encountered diseases, its symptom is nasal obstruction, many tears, headache and olfactory disorder etc., influences patient's quality of life, serious meeting influences patient's memory.Because nasal conchae hypertrophy, rhinostenosis, the nasal sinuses mouth stops up, and causes the secretions inadequate drainage of nasal cavity, treat very inconveniently, and the state of an illness is shown effect repeatedly, is difficult to effect a radical cure.Normal at present medicine and the operative treatment of adopting, owing to the problem that can not solve rhinostenosis, the effect of treatment neither be fine.
Summary of the invention
At the deficiencies in the prior art, this utility model provides a kind of rational in infrastructure, safe in utilization, a kind of nasal cavity balloon dilatation catheter that can effectively treat rhinitis, sinusitis.
This utility model is achieved through the following technical solutions:
This utility model comprises double channel catheter, main tube cavity, inflation base, switch valve, sublumen, air bag composition, and wherein, air bag is located at apart from 5cm place, double channel catheter top and with double channel catheter and is connected as a single entity.Described air bag is three-layer combined, from outside be respectively outer layer glue, fibrous layer, hose lining inwards, hose lining can expand rapidly when guaranteeing airbag aeration, and outer glue-line can shrink after making air bag deflation, and fibrous layer guarantees can not increase arbitrarily at the situation lower gasbag diameter that increases intracapsular pressure.
Double channel catheter is divided into main tube cavity and sublumen, and main tube cavity is provided with the inflation base for connecting the chamber in the rear end of double channel catheter, and inflation base one side is provided with switch valve, and sublumen is from the inflation base, and the head end opening is located in the air bag.
This utility model is according to the design of nasal cavity anatomical features, during use, the double channel catheter front end is inserted nasal cavity, gives airbag aeration by base, airbag inflation, thus reach the purpose that enlarges nasal meatus.The beneficial effects of the utility model are, with the narrow nasal meatus of balloon catheter expansion, the nasal meatus space are strengthened, and the nasal sinuses mouth is open, and the luminal sectetion thing is discharged, and reaches the purpose of curing rhinitis, sinusitis.This utility model is rational in infrastructure, dependable performance, cheap, has good popularization value.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, 1 double channel catheter, 2, main tube cavity, 3, inflation base 4, shut off valve, 5, sublumen 6, air bag
The specific embodiment
Embodiment: structure as shown in the figure, this utility model comprises that double channel catheter 1, main tube cavity 2, inflation base 3, switch valve 4, sublumen 5, air bag 6 form, wherein, air bag 6 is located at apart from double channel catheter 5cm place, 1 top and with double channel catheter 1 and is connected as a single entity.Described air bag 6 is three-layer combined, and from being respectively outer layer glue, fibrous layer, hose lining inwards outward, the diameter of air bag 6 can be 1.5cm.
