Anti-bubble infusion drip chamber

Abstract

The invention discloses an anti-bubble infusion drip chamber. The anti-bubble infusion drip chamber comprises a drip chamber main body; the drip chamber main body is provided with an upper part and alower part, namely a drip chamber part arranged on the upper portion and a filtering part arranged on the lower portion; the filtering part is provided with a liquid storage cavity communicating withan inner cavity of the drip chamber part, and a liquid medicine filter and an air filter which are arranged on two sides of the liquid storage cavity; a liquid medicine flow channel is arranged on theside wall of the filter and is provided with a liquid inlet and a liquid outlet; the liquid inlet is formed above the liquid outlet; a liquid medicine filter membrane is arranged between the liquid inlet of the flow channel and the liquid storage cavity; and the air filter is arranged on the drip chamber main body on at least one side of the filter membrane. A horizontally-placed liquid medicinefilter membrane in a traditional drip chamber can cause unsmooth flow of liquid medicine due to surface tension of the liquid medicine and accumulation of impurities; and by transforming the drip chamber, the liquid medicine filter membrane is vertically or obliquely arranged, so that on one hand, the impurities can be prevented from being accumulated on the surface of the filter membrane, and onthe other hand, the surface tension of the liquid medicine can be destroyed.

Description

technical field [0001] The invention relates to an infusion dripping funnel, in particular to an anti-bubble infusion dripping funnel, which belongs to the technical field of medical devices. Background technique [0002] At present, the common infusion set commonly used in the medical field is composed of a bottle stopper piercer protective cover, a bottle stopper piercer, a short infusion catheter, a short exhaust catheter, an air filter, an upper dropper, a drip funnel, a flow regulator, and a long infusion catheter. , liquid medicine filter and disposable intravenous infusion needle and other components. There are at least two problems in this infusion set: the one is that air bubbles are easily generated in the drip funnel and the catheter, which can easily cause hazards such as air embolism. The 2nd, the impurity in the medicinal liquid can enter human body. Therefore, the dropping funnel needs to have the functions of self-exhaust and liquid medicine filtration. ...

AI Technical Summary

Problems solved by technology

There are at least two problems in this infusion set: one is that air bubbles are likely to be generated in the drip funnel and the catheter, which may easily cause air embolism and other hazards.

Second, the impurities in the liquid will enter the human body

Although the above two problems have been solved to a certain extent, due to the influence of the surface tension of the liquid medicine and the accumulation of impurities on the liquid medicine filter membrane placed horizontally, the flow of the medicine liquid is not smooth.
