Abstract
The utility model provides a unidirectional valve device which can be put into a bronchus of the section which belongs to the lung target area through a bronchoscope. A semi-cambered valve which is made of polyester films for medical application is arranged in an outer sleeve which is surrounded by memory titanium-nickel alloy wires which are covered with the polyester film for medical application. The utility model presents a cylindrical shape, a tube cavity of the valve in the utility model is opened when people exhale, and the tube cavity is closed when the people inhale to achieve the purposes of reducing residual volume of the lung with pathological change and draining secretions; diseased lung zones are gradually fiberized and the healthy lung is gradually dilated to exert a compensating function; lung functions of patients are restored and the patients are healed.
Description
Affiliated technical field:
The present invention is particularly suitable for chronic obstructive pulmonary disease for the device of a kind of section of putting into or the following intrabronchial treatment pulmonary disease of section.
Background technology:
Treat chronic obstructive pulmonary disease, emphysema etc. at present, internal medicine is mainly with infection, and symptomatic treatment measures such as expansion capillary bronchus are main, can not effect a radical cure, and curative effect is relatively poor; Surgery is many based on lung volume reduction surgery, when since the pulmonary function of patient own is relatively poor often can not tolerate surgery, so mortality rate is higher, has limited operating application.
Summary of the invention:
For solving the problem of treatment difficulties such as chronic obstructive pulmonary disease, emphysema, the invention provides a kind of can be by the flap valve device of the bronchoscope unidirectional ventilation that segmental bronchus is put under the pulmonary target area, it is to have settled half an arc valve that the medical polyester film of usefulness is made in the overcoat that surrounds of memory Ti-Ni alloy silk of the medical polyester film of lining.It is open tube chamber when exhaling, and closes tube chamber when air-breathing.Insert pathological changes pulmonary position residual volume is reduced, secretions flows out, fibrosis gradually, and strong lung is expanded the performance compensation gradually, recovers patient's pulmonary function, heals the sick.
