Abstract
This utility model provides a kind of intestinal nutrient solution tube for transfusion extension exhaust apparatus, and comprise the column joint be arranged on tube for transfusion, described column joint is provided with exhaustor, described exhaustor and tube for transfusion UNICOM, the afterbody of exhaustor is provided with check valve.This utility model arranges this extension exhaust apparatus on intestinal nutrient solution tube for transfusion, can gas automatically in collection conduit, and outside timely discharge line, thus ensure that the fluid pressure in intestinal nutrient solution tube for transfusion is stablized, eliminate the thicker problem easily causing instillation not smooth in instillation process of nutritional solution; And have employed check valve, ensure that the air of outside can not enter intestinal nutrient solution tube for transfusion by exhaust apparatus, thus avoid nutritional solution in intestinal nutrient solution tube for transfusion contaminated.
Description
Technical field
This utility model belongs to medical apparatus and instruments, particularly a kind of intestinal nutrient solution tube for transfusion extension exhaust apparatus.
Background technology
Conventional disposable transfusion device instillation intestinal nutrient solution clinically, but in instillation process, easily cause instillation not smooth because nutritional solution is thicker, reason mainly disposable infusion catheter tip filtration is plugged with metafiltration paper, aperture is too thin, limit nutrient molecule through, need to use exhaust apparatus to be exhausted tube for transfusion, exhaust apparatus conventional at present as shown in Figure 1, tube for transfusion 10 cone joint 13 on offer venthole 11, and porose cap 12 is set, but this structure is appointed and is so existed because pressure is inadequate, does not have the problem of effect.In addition, also have a kind of mode to be penetrate tube for transfusion with pneumatic needle to make tube for transfusion aerofluxus, but there is increase infection in it, the problem that degree of safety is not high.
Utility model content
The purpose of this utility model is to provide a kind of intestinal nutrient solution tube for transfusion extension exhaust apparatus, to solve the problem of intestinal nutrient solution tube for transfusion aerofluxus.
For achieving the above object, this utility model is by the following technical solutions:
A kind of intestinal nutrient solution tube for transfusion extension exhaust apparatus, comprise the column joint be arranged on tube for transfusion, described column joint is provided with exhaustor, described exhaustor and tube for transfusion UNICOM, the afterbody of exhaustor 22 is provided with check valve.
Described exhaustor is L shape.
Valve body is provided with in described exhaustor, floating drum and float is provided with in valve body, one end connecting cylinder joint of valve body and with tube for transfusion UNICOM, the other end is connected with gas-collecting pipe, float fluctuates in floating drum inside, the top of floating drum is provided with air vent, and air vent connects gas-collecting pipe by discharge duct, and the tail end of gas-collecting pipe is disposed with stop valve and check valve.
The two ends up and down of described float and the two ends up and down of floating drum are equipped with.
The beneficial effects of the utility model are: on intestinal nutrient solution tube for transfusion, arrange this extension exhaust apparatus, can gas automatically in collection conduit, and outside timely discharge line, thus ensure that the fluid pressure in intestinal nutrient solution tube for transfusion is stablized, eliminate the thicker problem easily causing instillation not smooth in instillation process of nutritional solution; And have employed check valve, ensure that the air of outside can not enter intestinal nutrient solution tube for transfusion by exhaust apparatus, thus avoid nutritional solution in intestinal nutrient solution tube for transfusion contaminated.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing exhaust apparatus;
Fig. 2 is schematic diagram of the present utility model;
Fig. 3 is the internal structure schematic diagram of exhaustor.
Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, this utility model is described further.
As Fig. 2, a kind of intestinal nutrient solution tube for transfusion extension exhaust apparatus, comprises the column joint 21 be arranged on tube for transfusion 20, described column joint 21 is provided with the exhaustor 22 of a L shape, exhaustor 22 and tube for transfusion 20 UNICOM, the afterbody of exhaustor 22 is provided with check valve 227.
As Fig. 3, valve body 221 is provided with in exhaustor 22, floating drum 222 and float 223 is provided with in valve body, one end connecting cylinder joint 21 of valve body 221 and with tube for transfusion 20 UNICOM, the other end is connected with gas-collecting pipe 224, and float 223 fluctuates in floating drum 222 inside, and the top of floating drum 222 is provided with air vent 225, air vent 225 connects gas-collecting pipe 224 by discharge duct 226, and the tail end of gas-collecting pipe 224 is disposed with stop valve 228 and check valve 227.
The two ends up and down of float 223 and the two ends up and down of floating drum 222 are equipped with.
Principle of the present utility model is:
When nutritional solution enters the floating drum 222 in valve body 221, float 223 is just immersed in nutritional solution, and float 223 rises by the buoyancy of nutritional solution, and air vent 225 is withstood on float 223 top, thus by liquid seal in pipeline; When the gas in pipeline slowly generates, the density of gas can be lower than liquid, lighter gas slowly can float to peak, when the gas collected gets more and more, float 223 will because of the height reduction of liquid, buoyancy declines, float 223 will slowly decline, and will open the air vent 225 on top like this, when open, because internal pressure is greater than atmospheric pressure, gas will be discharged outside whole device, and along with the minimizing of gas, liquid can enter again in floating drum 222, by float 223 jack-up, close air vent 225.
