Description
Technical Field
The utility model relates to a transfusion system especially relates to a multi-functional transfusion system of liquid is only filtered to double exhaust multilayer precision.
Background
At present the transfusion system in the market is various, people are when using the transfusion system infusion, at first medical personnel can exhaust for the transfusion system, exhaust process need waste partly liquid medicine, because do not have obvious sign to come for medical personnel as the suggestion that the exhaust was accomplished, often medical personnel need extravagant a large amount of liquid medicines just can learn exhaust and accomplish, in addition be exactly when the infusion, if the liquid medicine liquid level in the dropping funnel of transfusion system is too high, will cause infusion fast, exhaust not smooth and easy, can lead to the bubble to enter into in the human body. In addition, when the liquid medicine in the infusion bottle is to be infused completely, the infusion needle needs to be pulled out of the human body, and the phenomenon of blood return can be caused if the infusion needle is not pulled out, so that the body of a patient is greatly damaged, even some infusion devices on the market can automatically stop infusion, long-term clinical practice proves that the phenomenon of blood return cannot be completely eliminated if the infusion is stopped.
In addition, some traditional Chinese medicine injections, fat emulsion injections, biological agents and the like are easy to generate insoluble particles when being combined, more impurities are in the inner parts, the infusion apparatus on the market cannot filter the particle impurities, and once the particle impurities enter the blood of a human body, the health of the human body can be directly influenced. Moreover, insoluble particles of the traditional Chinese medicine injection and the liquid after compatibility can block a precise filtration type infusion apparatus, so that the liquid discharge is difficult.
SUMMERY OF THE UTILITY MODEL
