Abstract
The utility model discloses a blood return preventing infusion device. The device comprises an infusion bottle; the infusion bottle is communicated with an infusion tube; the middle of the infusion tube is communicated with a liquid storage tube; a floating ball is arranged in the liquid storage tube; and the diameter of the floating ball is just enough for the floating ball to block a liquid outlet of the liquid storage tube. The device disclosed by the utility model has simple and skillful structural improvement and is convenient to manufacture; and when the liquid completely drops, the floating ball in the liquid storage tube sinks and blocks the liquid outlet of the liquid storage tube so as to prevent blood return.
Description
Technical field
This utility model relates to a kind of infusion set, mainly is a kind of infusion set of blood return prevention.
Background technology
Patient is when transfusion, if the nursing staff does not exist, perhaps patient is in again under the state of stupor, when the fluid drips in the infusion bottle is most, if in time do not pull out pin, can cause the phenomenon of backflow of blood, causes serious consequence.
The utility model content
This utility model technical problem to be solved provides a kind of infusion set of blood return prevention, and its architecture advances is simply gone ingenious, and is easy to make; Ball float when fluid drips is most in the liquid storage pipe sinks and has stopped up the liquid outlet of liquid storage pipe, has prevented the phenomenon that blood refluxes.
For solving the problems of the technologies described above, the technical scheme that this utility model adopts is:
A kind of infusion set of blood return prevention; Include infusion bottle, be communicated with tube for transfusion on the infusion bottle, the intermediate connection of said tube for transfusion has liquid storage pipe; It is characterized in that: be placed with a ball float in the described liquid storage pipe, the diameter of described ball float just in time can be stopped up the liquid outlet of liquid storage pipe.
The utility model when the reservoir tube with liquid, because of buoyancy, the float is floating on the liquid surface, and will not clog reservoir tube Alto fluid outlet; when the liquid droplets do, the float will drop live reservoir tube blockage The liquid outlet, the reservoir tube below the liquid in the tube is no longer infusion into the vein, the blood will not appear refluxing.
The utility model has the advantages that:
This utility model architecture advances is simply gone ingenious, and is easy to make; Ball float when fluid drips is most in the liquid storage pipe sinks and has stopped up the liquid outlet of liquid storage pipe, has prevented the phenomenon that blood refluxes.
Description of drawings
Fig. 1 is the structural representation of this utility model.
The specific embodiment
Referring to Fig. 1, a kind of infusion set of blood return prevention includes infusion bottle 1; Be communicated with tube for transfusion 2 on the infusion bottle 1; The intermediate connection of said tube for transfusion 2 has liquid storage pipe 3, is placed with a ball float 4 in the described liquid storage pipe 3, and the diameter of described ball float 4 just in time can be stopped up the liquid outlet of liquid storage pipe 3.
