Description
Technical field
This utility model relates to medical auxiliary equipment field, is especially the anti-blocking anti-error suction Y type enteral nutrition tube for transfusion of negative pressure.
Background technology
During with intestinal nutrient solution tube for transfusion to sufferer enteral conveying nutritional solution, first must confirm whether the end that pipeline is positioned at human body enters the intestines and stomach, if pipeline grafting mistake enters trachea, thus cause nutritional solution to enter trachea causing inhaling producing serious malpractice by mistake, after existing Y type intestinal nutrient solution tube for transfusion enters human body, by medical personnel the upper part of pipeline extracted and be connected with the outlet of syringe, corresponding body fluid can be extracted judge pipeline by observing syringe whether grafting is correct, comparatively inconvenience, and the impurity of formation in existing pipeline effectively can not be got rid of and easily causes pipeline to be had a stuffy nose, in view of the foregoing, existing intestinal nutrient solution tube for transfusion is generally one-off, comparatively waste.
Summary of the invention
This utility model object is to solve the problem, and provides the anti-blocking anti-error suction Y type enteral nutrition tube for transfusion of a kind of negative pressure, is specifically realized by following technical scheme:
The anti-blocking anti-error suction Y type enteral nutrition tube for transfusion of a kind of negative pressure, comprise and be connected to filter chamber in Y type tube for transfusion and the sacculus in parallel with described filter chamber, the bottom of described filter chamber is provided with the filter screen of inverted V-shaped, and the below of described filter screen is provided with the outlet that other parts of filter chamber and pipeline are connected; Accumulation of impurities district is formed between the bottom margin of described filter screen and the inwall of filter chamber; The two ends up and down of described sacculus are respectively arranged with check valve, and the check valve being positioned at sacculus bottom is communicated with the upper end, blowdown room that inside has blowdown filter screen; The bottom of blowdown room is communicated with described accumulation of impurities district by pipeline.
The anti-blocking anti-error suction Y type enteral nutrition tube for transfusion of described negative pressure, it designs further and is, the pipeline in the pipeline between the check valve on sacculus top with Y type tube for transfusion, the pipeline at filtering chamber inlet place, exit, filter chamber and the pipeline between blowdown room with described accumulation of impurities district are provided with the stopped pipe can closing corresponding pipeline and press from both sides.
The anti-blocking anti-error suction Y type enteral nutrition tube for transfusion of described negative pressure, its further design be, the lower end of described blowdown room is provided with waste, and this exit has been threaded drain plug.
This utility model by taking over the ball valve that filter chamber and bottom are connected with blowdown room in Y type tube for transfusion, and at the two ends of ball valve, check valve is set, make this utility model pipeline grafting can be checked under the prerequisite without the need to plug pipeline whether correct, and can in time the food debris of filter chamber be carried out collecting and getting rid of, avoid pipeline blockage, thus make this utility model can repeatedly Reusability, save resource.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, this utility model is further described.As Figure 1-Figure 4, the anti-blocking anti-error suction Y type enteral nutrition tube for transfusion of this negative pressure comprises and is connected to filter chamber 1 in Y type tube for transfusion and the sacculus 2 in parallel with filter chamber, the bottom of filter chamber 1 is provided with the filter screen 11 of inverted V-shaped, and the below of filter screen 11 is provided with the outlet that other parts of filter chamber and pipeline are connected; Accumulation of impurities district 12 is formed between the bottom margin of filter screen and the inwall of filter chamber; The two ends up and down of sacculus 2 are respectively arranged with check valve 21, and the check valve being positioned at sacculus bottom is communicated with the upper end, blowdown room 3 that inside has blowdown filter screen 31; The bottom of blowdown room is communicated with accumulation of impurities district by pipeline.
Pipeline between check valve on sacculus top with Y type tube for transfusion, the pipeline at filtering chamber inlet place, the pipeline in exit, filter chamber and the pipeline between blowdown room with accumulation of impurities district are provided with the stopped pipe can closing corresponding pipeline and press from both sides (stopped pipe press from both sides belong to prior art do not repeat at this), are correspondingly denoted as A point, B point, C point, D point in the drawings.
The lower end of blowdown room 3 is provided with waste, and this exit has been threaded drain plug 32.
When checking pipeline grafting be correct, B point pinch off, now pinching sacculus, air in sacculus is upwards discharged, when unclamping sacculus, produces negative pressure when sacculus recovers deformation and suction is produced to the end that pipeline is positioned at human body, gas-liquid flow is to shown in arrow points in such as Fig. 5, after repeatedly repetition pinching unclamps sacculus, observe and whether have corresponding body fluid to enter pipeline, if having, then pipeline connects correct, as nothing, then pipeline grafting mistake, needs grafting again.
When normally using, can by A point, D point pinch off, now nutritional solution enters in human body through the strainer filtering of filter chamber.
When the accumulation of impurities district of drainage screen bottom assemble have a certain amount of impurity time, C point pinch off, also pinch off E point simultaneously can be considered, now repeatedly pinching, unclamp sacculus, make the impurity being positioned at accumulation of impurities district constantly flow to blowdown room and assemble in the bottom of blowdown room, after infusion-completed, open drain plug and blowdown room is cleared up.
This utility model by taking over the ball valve that filter chamber and bottom are connected with blowdown room in Y type tube for transfusion, and at the two ends of ball valve, check valve is set, make this utility model pipeline grafting can be checked under the prerequisite without the need to plug pipeline whether correct, and can in time the food debris of filter chamber be carried out collecting and getting rid of, avoid pipeline blockage.
