Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to unidirectional valve formula drainage system.
Background technology
For a long time, in clinical position, especially surgical postoperative, because the various lacunas of human body need to carry outNegative pressure drainage, to discharge pneumatosis and the hydrops in lacuna, must use one-way fashion drainage bottle, clinical at presentMiddle used drainage system bottle is all plastic bottle or drainage tube, and below connects glass or plastics water-sealed drainage bottle,Application atmospheric pressure maintains unidirectional suction function, but find that there is in clinical use, following several respects are fatal to be lackedFall into: 1. drainage bottle heaviness, patient carries inconvenience; 2. junction easily comes off; 3. plastic bottle or glass drainage bottleEasily break, easily topple over because family members nurse the improper drainage bottle that causes, the lacunas such as thoracic cavity, abdominal cavity are with outerBoundary communicates, and then causes pneumothorax, abdominal cavity or thoracic cavity infection etc.; Above the 2nd, 3 or kind situation occur time,Usually cause mortality danger.
Summary of the invention
The object of this invention is to provide unidirectional valve formula drainage system, carry not to solve existing drainage bottleJust, easily come off and easily break, even life-threatening problem.
The technical scheme that invention adopts is that unidirectional valve formula drainage system, comprises one or several stringsThe drainage unit of connection, drainage unit comprises the urceolus of hollow, the upper end of urceolus is that entrance and lower end are outlet,In urceolus, be provided with thin-film check valve, thin-film check valve comprises symmetrically arranged two films, twoFilm includes the epimere of inclination and vertical hypomere, two epimeres composition fall infundibulate forming be positioned at intoThe liquid-inlet passage of mouthful below, the edge of two epimeres all with the inwall close contact of urceolus and the company of fixingConnect, two hypomeres are bonded to each other and form the liquid outlet passage that is positioned at outlet top.
Feature of the present invention is also,
Also comprise the hollow inner cylinder for fixing two films, inner core is coaxially closely fixedly installed on urceolusIn, the upper end of inner core is for falling infundibulate, and the epimere of two films is fixed on the upper end of inner core.
Inner core is made up of the arch housing of two opposite openeds in left and right.
In urceolus, be provided with the draw-in groove for fixing inner core position.
Draw-in groove is the boss arranging around outer tube inner wall.
The hypomere of two films extends downward the below of inner core.
Entrance is to the inner inverted round stage shape extending of urceolus.
The inverted round stage shape of outlet for extending to urceolus below.
The angle of the epimere of two films and the hypomere corresponding with it is 100 °～150 °.
Two films are Emulsoid-film, and the material of urceolus is polyvinyl chloride.
The invention has the beneficial effects as follows, the entrance of unidirectional valve formula drainage system connects drainage tube, and outlet is straightConnect in succession negative pressure drainage bag, when no matter in drainage bag, pressure occurs which kind of changes, the gas in lacuna and liquidBody all can be unidirectional by this device, and two photoplate films are due to the reason of air pressure and surface tension of liquid simultaneouslyBonded to each other tight, can effectively prevent the backflow of gas liquid. The present invention is simple in structure, simple operation,Under connect common negative pressure drainage bag and can use, be convenient for carrying, and without traditional water-sealed drainage bottle because toppling over, break instituteCause the shortcoming of drainage failure, result of use highly significant.

Fig. 2 is the structural representation of unidirectional valve formula drainage system inner core of the present invention.
In figure, 1. inner core, 2. epimere, 4. hypomere, 5. urceolus, 6. boss, 7. entrance, 8. outlet.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
The invention provides a kind of unidirectional valve formula drainage system, referring to Fig. 1, unit comprises the urceolus of hollow5, the upper end of urceolus 5 is that entrance 7 and lower end are outlet 8, is provided with thin-film check valve in urceolus 5,Thin-film check valve comprises symmetrically arranged two films, and two films include the epimere 2 of inclination and erectThe angle of the epimere 2 of straight 4, two films of hypomere and the hypomere 4 corresponding with it is 100 °～150 °,Two epimeres 2 form to fall infundibulate and form the liquid-inlet passage that is positioned at entrance 7 belows, two epimeres2 edge is all with the inwall close contact of urceolus 5 and be fixedly connected with, the bonded to each other and shape of two hypomeres 4Become to be positioned at the liquid outlet passage of outlet 8 tops.
Referring to Fig. 2, also comprise the hollow inner cylinder 1 for fixing two films, inner core 1 is coaxial closely solidSurely be arranged in urceolus 5, the upper end of inner core 1 is for falling infundibulate, in the epimere 2 of two films is fixed onThe upper end of cylinder 1, the hypomere 4 of two films extends downward the below of inner core 1.
Two films are Emulsoid-film, and the thickness of the Emulsoid-film on epimere 2 and hypomere 4 is 1cm,Can guarantee to occur negative pressure time, between two films, laminating closely, be avoided the refluence of gas, liquid.
In clinical practice, inner core 1 can be an entirety, also can be by two of left and right opposite openedArch housing composition, these two arch housings can be two semicolumn housings, these two semicolumn housingsIn the time of closure, form a cylinder.
In urceolus 5, be provided with the draw-in groove for fixing inner core 1 position, draw-in groove is around urceolus 5 inwall settingsBoss 6, entrance 7 is that outlet 8 is to urceolus 5 belows to the inner inverted round stage shape extending of urceolus 5The inverted round stage shape extending.
The entrance 7 of urceolus 5 can with drainage tube seamless link, the outlet 8 of urceolus 5 can with negative pressure drainage bagOr the entrance 7 of another drainage unit connects, realize the series connection of several drainage unit, if one is drawnUnidirectional valve in stream unit blocks, and just can replace at any time, easy to use and reliable, guarantees unidirectionalThe reliability of flap valve effect.
Film on each inner core 1 bottom surface 3 all extends to the outside of inner core 1 bottom, the hypomere 4 of filmExceed inner core 1 bottom 1cm, can guarantee the better effects if of unidirectional valve device unidirectional drainage.
The material of inner core 1 and urceolus 5 is PVC polyvinyl chloride or other hard materials, for anti-Press and keep overall stable form, having ensured can be because external pressure causes device distortion, latex materialIn the time being subject to external force, can there is deformation in the film of matter, while not being subject to external force, can maintain the original state, so this filmDesign, has achieved one-way function, and can be because of careless operation, causes inner non-return device to loseLose, in the time connecting use, be more conducive to change at any time.
When work, by entrance 7 and drainage tube seamless link, in the time that patient exhales and cough, in its bodyGas and liquid only can pass through from entrance 7 is unidirectional, and from exporting 8 discharges; Two breasts in the time that patient is air-breathingGlue film is because air pressure reason is bonded to each other closely, prevented the backflow of gas, liquid, realized unidirectionalThe effect of drainage. The present invention is little because installing, simple operation, under connect common negative pressure drainage bag and can use,Be convenient for carrying, and without traditional water-sealed drainage bottle the shortcoming because of drainage failure due to toppling over, breaking, result of use is non-Chang Xianzhu.
