Description

Unidirectional valve formula drainage system
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 out negative pressure drainage, to discharge pneumatosis and the hydrops in lacuna, must use one-way fashion drainage bottle, clinical middle used drainage system bottle is all plastic bottle or drainage tube at present, and below connects glass or plastics water-sealed drainage bottle, and application atmospheric pressure maintains unidirectional suction function, but in clinical use, find that there is following several respects critical defect: 1. drainage bottle heaviness, patient carries inconvenience; 2. junction easily comes off; 3. plastic bottle or glass drainage bottle easily break, and easily topple over because family members nurse the improper drainage bottle that causes, and the lacunas such as thoracic cavity, abdominal cavity communicate with the external world, and then cause 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 inconvenience, easily come off and easily break, even life-threatening problem to solve existing drainage bottle.
The technical scheme that invention adopts is, unidirectional valve formula drainage system, comprise the drain unit of one or several series connection, drain 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 thin film, two thin film include the epimere of inclination and vertical hypomere, two epimeres form to fall infundibulate and form the liquid-inlet passage that is positioned at entrance below, the edge of two epimeres is all with the inwall close contact of urceolus and be fixedly connected with, 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 thin film, inner core is coaxially closely fixedly installed in urceolus, and the upper end of inner core is for falling infundibulate, and the epimere of two thin film 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 thin film 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 thin film and the hypomere corresponding with it is 100 °~150 °.
Two thin film are Emulsoid-film, and the material of urceolus is polrvinyl chloride.
The invention has the beneficial effects as follows, the entrance of unidirectional valve formula drainage system connects drainage tube, outlet directly connects negative pressure drainage bag, when no matter in drainage bag, pressure occurs which kind of changes, gas in lacuna and liquid all can be unidirectional by this device, two photoplate thin film, because the reason of air pressure and surface tension of liquid is bonded to each other closely, can effectively prevent the backflow of gas liquid simultaneously.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 the shortcoming because of drain failure due to toppling over, breaking, result of use highly significant.
Brief description of the drawings
Fig. 1 is the structural representation of unidirectional valve formula drainage system of the present invention;
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 5 of hollow, the upper end of urceolus 5 is that entrance 7 and lower end are outlet 8, in urceolus 5, be provided with thin-film check valve, thin-film check valve comprises symmetrically arranged two thin film, two thin film include the epimere 2 of inclination and vertical hypomere 4, the angle of the epimere 2 of two thin film 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, the edge of two epimeres 2 is all with the inwall close contact of urceolus 5 and be fixedly connected with, two hypomeres 4 are bonded to each other and form the liquid outlet passage that is positioned at outlet 8 tops.
Referring to Fig. 2, also comprise the hollow inner cylinder 1 for fixing two thin film, inner core 1 is coaxially closely fixedly installed in urceolus 5, and the upper end of inner core 1 is for falling infundibulate, the epimere 2 of two thin film is fixed on the upper end of inner core 1, and the hypomere 4 of two thin film extends downward the below of inner core 1.
Two thin film are Emulsoid-film, and the thickness of the Emulsoid-film on epimere 2 and hypomere 4 is 1cm, and can guarantee to occur negative pressure time, between two thin film, laminating closely, be avoided the refluence of gas, liquid.
In clinical practice, inner core 1 can be an entirety, also can be made up of the arch housing of two opposite openeds in left and right, and these two arch housings can be two semicolumn housings, and these two semicolumn housings form a cylinder in the time of closure.
In urceolus 5, be provided with the draw-in groove for fixing inner core 1 position, draw-in groove is the boss 6 arranging around urceolus 5 inwalls, and entrance 7 is to the inner inverted round stage shape extending of urceolus 5, and outlet 8 is the inverted round stage shape extending to urceolus 5 belows.
The entrance 7 of urceolus 5 can with drainage tube seamless link, the outlet 8 of urceolus 5 can be connected with the entrance 7 of negative pressure drainage bag or another drain unit, realize the series connection of several drain unit, if the unidirectional valve in a drain unit blocks, just can replace at any time, easy to use and reliable, guarantee the reliability of unidirectional valve effect.
Thin film on each inner core 1 bottom surface 3 all extends to the outside of inner core 1 bottom, and the hypomere 4 of thin film exceedes 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 polrvinyl chloride or other hard materials, be used for resistance to compression and keep overall stable form, having ensured can be because external pressure causes device distortion, and the thin film of latex material, in the time being subject to external force, deformation can occur, and while not being subject to external force, can maintain the original state, so design of this thin film, achieve one-way function, and can be because of careless operation, inner non-return device failure caused, 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, the gas in its body and liquid only can pass through from entrance 7 is unidirectional, and from exporting 8 discharges; In the time that patient is air-breathing, two Emulsoid-films are because air pressure reason is bonded to each other closely, have prevented the backflow of gas, liquid, have realized the effect of unidirectional 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 drain failure due to toppling over, breaking, result of use highly significant.
