Description
Technical field
The present invention relates to be particularly suitable for medical valve or valve gear technical field, specifically is a kind of be fit to plant section or intrabronchial check valve apparatus below the section under pulmonary rake district.
Background technology
Treat emphysema, pulmonary belb, chronic obstructive pulmonary disease 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 weak curative effect.Surgery is many based on lung volume reduction surgery, often can not tolerate surgery because the pulmonary function of patient own is relatively poor, and mortality rate is higher, so limited operating application.The present inventor had once invented " unidirectional flap valve device in a kind of trachea ", and patent publication No. is that its structure of CN2749468 is a cylinder sleeve, has settled one to make the mobile half arc valve of gas unidirectional in the cover.Weak point is to place inconvenience, and applicable surface is narrow, is very limited so it is applied.
Summary of the invention
The purpose of this invention is to provide a kind of trachea internal check valve, characteristics such as it has placement, fixing, easy to use, and patient's misery is little, and therapeutic effect is good, and is applied widely.Be particularly suitable for the treatment of emphysema and chronic obstructive pulmonary disease.
Main technical schemes of the present invention is: a kind of trachea internal check valve, comprise one-way cock, it is characterized in that having compressible place come out in the carrier after restorative elastic valve body frame of expansible and fixed structure thereof again.
Above-mentioned trachea internal check valve is characterized in that being provided with valve body frame supporting ﹠ stablizing seat.Place use fast, steadily, accurately so that make the valve body frame.
Above-mentioned valve body frame can constitute claw-like or pyramid-shaped by 2, elastic fulcrum bar more than 3 or 3.
In order to make its compact conformation reasonable, in light weight, claw-like or pyramid-shaped valve body frame that above-mentioned elastic fulcrum bar constitutes, the best is tapered jaw shape or slant edge taper, and valve body frame supporting ﹠ stablizing seat is arranged on the short one side of elastic fulcrum bar.
In order to make its structure simpler, effective, above-mentioned valve body frame supporting ﹠ stablizing seat the best be one all link to each other with elastic fulcrum bar and and lumen shaft line parallel and tube chamber supporting rod on one side, the bar head preferably is provided with the clamp structure of being convenient to take out.This supporting ﹠ stablizing seat also can be structures such as arc plate shape.
Above-mentioned fixed structure can be one and be connected in compressible on vavle shelf or the valve body frame supporting ﹠ stablizing seat and place in the carrier again that the restorative valve body frame that makes of expansible is fixed in endotracheal flexible fastening anchor.
In order to make it simple in structure, to put, get, fixing more convenient, effective, this flexible fastening anchor the best is one and is scorpion tail type and with the flexible fastening hook of agnail.
Above-mentioned fixed structure also can be: be equipped with grasp in the outer end of 3 elastic fulcrum bars of different azimuth at least, it more stably is fixed on the wall of chamber.Or be other structures.
Above-mentioned one-way cock is good with film pocket type valve, the flexible film bag mouth intermittently is fixed in the outer end of melon shape elastic fulcrum bar, the bag body is fixed in or is blocked in or overcoat and being fixed on the elastic fulcrum bar, strutted in the thin film of trachea intracavity by elastic fulcrum bar and in trachea, to form unidirectional flap valve, air-flow from the bag mouth direction makes bag film be affixed on the trachea inner chamber, stop air-flow to enter, make thin film in trachea, form unidirectional band gap flap valve, make gas unidirectional mobile from the air-flow of direction at the bottom of the bag.Check valve is gate-type also, and has the scalable and open plane formula diaphragm seal that is fixed on the elastic fulcrum bar skeleton, and this moment, thin film can connect sealing by the outer end elasticity circular arc bar that is fixed in melon shape elastic fulcrum bar skeleton.
Above-mentioned valve body frame also can be one by a plurality of compressible oblique springs constitute by central point or the outside opening type elastic skeleton of adapter ring, tiltedly springs can be 2, more than 3 or 3.Check valve can be a gate-type, in the middle of can placing, and has the telescopic plane formula diaphragm seal that can be fixed on the springs, and this thin film can connect sealing by the elasticity circular arc bar that is fixed in the springs outer end.Check valve also can be the film pocket type, and bag end one side can be provided with the bag end fixed structure that links to each other with the valve body frame.And can be provided with valve body frame supporting ﹠ stablizing seat and fixed structure.The valve body frame also can be other compressible elastic recovery structure.
Above-mentioned have can compress the elastic valve body frame that places in the carrier and fixed structure thereof, valve body frame supporting ﹠ stablizing seat to be made for good with the Nitinol memory metal material.
Insert for convenience, above-mentioned check valve, configurable have a flexible tubular carrier, and the check valve compression is placed the carrier flexible pipe, is provided with the check valve push rod in the pipe.
Check valve is generally inserted or is taken out by the biopsy hole of trachea chamber mirror.During taking-up, can earlier support be become flexible displacement or make its contraction distortion, on valve body frame or the valve body frame supporting ﹠ stablizing seat taking-up matching structure can be arranged.
Good effect of the present invention is: with check valve of the present invention, be presented in affiliated section in pulmonary target area or the following bronchus of section, can make its open tube chamber during expiration, can make it close tube chamber when air-breathing, thereby pathological changes pulmonary position residual volume is reduced, and secretions flows out, the sick pulmonary collapse or fibrosis, strong lung is expanded the performance compensation gradually, improves patient's pulmonary function; The present invention has overcome the deficiency of prior art, has reached goal of the invention fully, has placement, fixing, easy to use, therapeutic effect is good, and advantage of wide range of application is especially placed convenient, fast, steady, accurate, fixing reliable, patient's misery is little, and patient is in case find in good time undesirablely to go out or convenient the taking-up, simple and compact for structure, suitable, use, curative effect is reliable, facilitating operation, simple, save time, have no side effect, the cure rate height can extensive use in clinical practice.Solved better that people thirst for solving for a long time but the treatment difficult problem of still unsolved so far emphysema, chronic obstructive pulmonary disease etc. has big application value.Be particularly suitable for the especially treatment of limitation emphysema and chronic obstructive pulmonary disease of emphysema.
Be described further below in conjunction with embodiment, but not as a limitation of the invention.
