Abstract
Disclosed is a blood retro-flow prevention infusion set, which includes a dripping bottle and a duct, a floating ball is arranged in the dripping bottle, the shape of lower part of the dripping bottle near the lower pipe mouth can fit with the shape of the lower part of the floating ball, and the utility model has advantages of simple structure, reliable movement and effective blood retro-flow prevention.
Description
Technical field
This utility model belongs to a kind of medical apparatus, particularly a kind of blood return preventing infusion device.
Background technology
Existing transfusion device is to be made of conduit, Liquid dropping bottle, and when the basic emptying of transfusion device inner liquid medicine, blood back phenomenon in the conductive pipe can appear in transfusion place of patient skin surface, and the patient is not felt well.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of simple in structure, reliable in action is provided, and can effectively prevents the blood return preventing infusion device that the blood back phenomenon takes place.
This utility model is achieved in that it is made of Liquid dropping bottle, conduit, and its special character is to be placed with ball float in Liquid dropping bottle, and said Liquid dropping bottle bottom matches near lower nozzle place shape and ball float lower shape.
According to above-mentioned blood return preventing infusion device, one and the corresponding guide pillar of Liquid dropping bottle lower nozzle are arranged in the lower end of ball float.
The utility model has the advantages that simple in structure, reliable in action, can effectively prevent the generation of blood back phenomenon.
Description of drawings
Fig. 1 is the structural representation of this blood return preventing infusion device;
The structural representation of this blood return preventing infusion device when Fig. 2 is transfusion.
The specific embodiment
As shown in the figure, this blood return preventing infusion device is made of Liquid dropping bottle 2, conduit 1,4, it is placed with the hollow float of being made by plastic material 3 in Liquid dropping bottle 1, said Liquid dropping bottle 1 bottom matches near the shape of lower nozzle position and ball float 3 bottoms, have one to be the guide pillar 3A of one with ball float 3 in the lower end of ball float 3, said guide pillar 3A is corresponding with the lower nozzle 2A of Liquid dropping bottle.
When reality is used, when this blood return preventing infusion device with after medicine bottle communicates, medicinal liquid is entered in the Liquid dropping bottle 2 by Liquid dropping bottle 2 upper orifices, and Liquid dropping bottle 2 is tilted to place, after medicinal liquid was full of, ball float 3 floated, medicinal liquid is flowed out through conduit 4 by Liquid dropping bottle 2 lower nozzle 2A.When in the Liquid dropping bottle 2 during no medicinal liquid, ball float 3 falls automatically, and guide pillar 2A is because action of gravity falls into Liquid dropping bottle 2 lower nozzle 2A, and 2A blocks with lower nozzle, thereby prevents the generation of blood back phenomenon.
