Description
Technical field
This utility model relates to a kind of anti-backflow device, specifically, is a kind of water-sealed drainage bottle anti-backflow device, belongs to technical field of medical instruments.
Background technology
Water-sealed drainage bottle is the basic device of enclosed drainage of pleural cavity, enclosed pleural drainage is the important measures for the treatment of pneumothorax, hemothorax and empyema, it is a base therapy measure of thoracic surgery, enclosed pleural drainage is that the liquid in the dependence water-sealed drainage bottle designed according to the physiological characteristics of human body pleural space makes pleural space be isolated from the outside, form airtight device, keep the negative pressure of pleural space, when pleural space endogenous cause of ill hydrops or pneumatosis form high pressure, pleura intracavity liquid or gas can drain in drainage bottle.
The inside of water-sealed drainage bottle is equipped with water seal cavity, by the water in water seal cavity, water seal is implemented to vacuum draw, but once the pressure differential of water seal two end causes water column rapid retrograde flow, the process flowing to fluid collection chamber from water seal cavity is referred to as to flow backwards, if can not closing retrograde passage instantaneously, then the liquid of water seal cavity can be made to backflow rapidly in fluid collection chamber because of siphonage, cause water seal failure, air enters fluid collection chamber from outside thus enters to pleural space and produces pneumothorax.
Summary of the invention
This utility model technical issues that need to address are: existing water-sealed drainage bottle, once water sealing (sealing water) pipe water level two end pressure difference is excessive, the water in water seal cavity may flow backwards, and causes adverse consequences to patient, there is certain potential safety hazard.
This utility model takes following technical scheme:
A kind of water-sealed drainage bottle anti-backflow device, in water-sealed drainage bottle, backflow preventer is set, described backflow preventer comprises the stiff end 7 on top, described stiff end bottom is fixedly connected with at least one fairlead 5, in described fairlead 5, guide rod 4 is set, guide rod 4 lower end is fixedly connected with diaphragm 1, and described diaphragm 1 lower end is connected with float valve body 2; Described stiff end 7 is fixedly installed on the outside top of water-sealed drainage bottle water seal cavity 3, and water seal cavity 3 top has suction entrance, and guide rod 4 is through described suction entrance, and it is inner that diaphragm 1, float valve body 2 are all positioned at water seal cavity 3; When the water in water seal cavity 3 occurs to flow backwards, float valve body 2 floats together with diaphragm 1, guide rod 4, is blocked by described suction entrance.
The feature of the technical program is: for water-sealed drainage bottle devises a kind of special anti-backflow device, utilize the gravity of float valve body self and be subject to the buoyancy of the water surface, float valve body naturally droops and is in open state, when water sealing (sealing water) pipe two end pressure difference is excessive, when the water in water seal cavity occurs to flow backwards, water seal cavity liquid upper punch pushes down float valve body, under the effect of hydraulic pressure, float valve body pushes up, diaphragm is pushed down and is pumped into mouth, now valve closing, prevents the refluence of water seal cavity liquid.
Described float valve body 2 is in prismatoid structure, and upper surface is less, and lower surface is larger.
Described diaphragm 1 is rubber diaphragm.
Each water seal cavity 3 is corresponding with a float valve body 2.
The beneficial effects of the utility model are:
1) effectively prevent water-sealed drainage bottle from flowing backwards, reliability, the safety of water-sealed drainage bottle promote greatly.
2) structure is simple, and it is convenient to implement.
3) design ingenious, easy to use.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
A kind of water-sealed drainage bottle anti-backflow device, in water-sealed drainage bottle, backflow preventer is set, described backflow preventer comprises the stiff end 7 on top, described stiff end bottom is fixedly connected with at least one fairlead 5, in described fairlead 5, guide rod 4 is set, guide rod 4 lower end is fixedly connected with diaphragm 1, and described diaphragm 1 lower end is connected with float valve body 2; Described stiff end 7 is fixedly installed on the outside top of water-sealed drainage bottle water seal cavity 3, and water seal cavity 3 top has suction entrance, and guide rod 4 is through described suction entrance, and it is inner that diaphragm 1, float valve body 2 are all positioned at water seal cavity 3; When the water in water seal cavity 3 occurs to flow backwards, float valve body 2 floats together with diaphragm 1, guide rod 4, is blocked by described suction entrance.
Described float valve body 2 is in prismatoid structure, and upper surface is less, and lower surface is larger.
Described diaphragm 1 is rubber diaphragm.
Each water seal cavity 3 is corresponding with a float valve body 2.
This utility model is that water-sealed drainage bottle devises a kind of special anti-backflow device, utilize the gravity of float valve body self and be subject to the buoyancy of the water surface, float valve body naturally droops and is in open state, when the pressure differential of water sealing (sealing water) pipe two end is excessive, when the water in water seal cavity occurs to flow backwards, water seal cavity liquid upper punch pushes down float valve body, under the effect of hydraulic pressure, float valve body pushes up, diaphragm is pushed down and is pumped into mouth, now valve closing, prevents the refluence of water seal cavity liquid.
This utility model effectively prevents water-sealed drainage bottle from flowing backwards, and reliability, the safety of water-sealed drainage bottle promote greatly; Structure is simple, and it is convenient to implement; Design ingenious, easy to use.
