Abstract
Provided is a safe infusion device. The safe infusion device comprises an infusion hose, a bottle stopper puncture device, an air inlet tube and a long bottle stopper puncture device, wherein one end of the infusion hose is connected with the bottle stopper puncture device, the air inlet tube is connected with the lengthened bottle stopper puncture device, and the length of the long bottle stopper puncture device is larger than the height of the liquid level of an infusion container. Due to the fact that the lengthened bottle stopper puncture device is adopted on the safe infusion device, air can directly reach to the upper portion of the liquid level in a bottle without contacting with the liquid in the bottle, and contamination to the liquid in the bottle is greatly reduced.
Description
Technical field
This utility model relates to a kind of transfusion device, is specially a kind of a kind of safe transfusion system that prevents contaminated liquid in the infusion process.
Background technology
Present a kind of safe transfusion system is in infusion process, and the liquid in the bottle flows into the human vein blood vessel by bottle plug puncture unit and infusion tube, because the effect of atmospheric pressure, the outer air of bottle enters in the bottle by air inlet pipe, bottle plug puncture unit.Because bottle plug puncture unit is positioned at below the bottle liquid level, therefore a bottle outer air enter bottle all will be through more than the arrival liquid level behind the liquid when interior, airborne like this microorganism and other impurity just probably pollute a bottle interior liquid.
Summary of the invention
For the deficiency on the above-mentioned prior art, this utility model provides a kind of safe transfusion system.This a kind of safe transfusion system passes through newly-increased lengthening bottle plug puncture unit, can make bottle outer air in the situation that do not contact above the interior liquid level of the direct arrival bottle of bottle interior liquid, has reduced the pollution to liquid in the bottle.
The technical solution of the utility model is: a kind of safe transfusion system, comprise infusion tube, bottle plug puncture unit, air inlet pipe, wherein, one end of infusion tube connects bottle plug puncture unit, it is characterized by: described air inlet pipe and lengthens bottle plug puncture unit and is connected, and lengthens the length of bottle plug puncture unit greater than the height of liquid level in the infusion vessel.
The beneficial effects of the utility model are: thus avoid when the bottle outer air enters in the bottle in infusion process and the direct contaminated liquid that contacts of liquid.
Description of drawings
Fig. 1 is the structural representation of the present disposable transfusion device of commonly using.
Fig. 2 is the structural representation of a kind of safe transfusion system of the present utility model.
Among the figure, the 1-infusion tube, the 2-bottle plug puncture unit, the 3-air inlet pipe, the 4-infusion bottle, 5-lengthens bottle plug puncture unit.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
Such as Fig. 2, a kind of safe transfusion system of this utility model comprises infusion tube 1, bottle plug puncture unit 2, air inlet pipe 3, lengthens bottle plug puncture unit 5.Infusion tube 1 is connected with bottle plug puncture unit 2, and air inlet pipe 3 is connected with lengthening bottle plug puncture unit 5, and the length of bottle plug puncture unit 5 is greater than the height of liquid level in the infusion bottle 4.
Before the transfusion, at first bottle plug puncture unit 2 is inserted in the infusion bottle 4 with lengthening bottle plug puncture unit 5, the front end that lengthens bottle plug puncture unit 5 is inserted into more than the liquid level.In infusion process, liquid in the infusion bottle 4 is by bottle plug puncture unit 2 and infusion tube 1 input human vein blood vessel, there is pressure difference inside and outside the infusion bottle 4, extraneous air enters in the bottle by air inlet pipe 3 and lengthening bottle plug puncture unit 5, owing to lengthening the front end of bottle plug puncture unit more than liquid level, therefore extraneous air can directly enter in the air layer of infusion bottle 4 tops, rather than through with the contacting of liquid after arrive again air layer.So namely reduce extraneous air and contacted with the direct of liquid, thereby effectively avoided air pollution to liquid in the bottle when entering infusion bottle 4.
Claims (1)
