Abstract

The invention discloses a filter and an infusion apparatus used for infusion apparatus fine filtration. The filter used for infusion apparatus fine filtration comprises a filter base, a filter cover and a filter membrane which is clamped between the filter base and the filter cover. The filter base and the filter membrane form an exhaust cavity, a liquid collecting cavity is formed by the filter cover and the filter cover on the lower portion of the exhaust cavity, and a liquid inlet passage which is communicated with the exhaust cavity and a liquid outlet passage which is communicated with the liquid collecting cavity are formed in the filter cover. An exhaust passage which is communicated with the exhaust cavity is formed in the side face of the filter base, liquid which is located in the exhaust cavity is filtered through the filter membrane and enters the liquid collecting cavity, and filtered air is discharged from the infusion apparatus through the exhaust passage. The filter infusion apparatus used for infusion apparatus fine filtration can effectively discharge air in the liquid, avoids that the air is infused with the liquid into a human man blood vessel, reduces risks of medical negligence and is compact in structure, convenient to use and high in safety performance in using process.

Description

technical field [0001] The invention relates to a medical device, in particular to a filter and an infusion set for precise filtration of an infusion set. Background technique [0002] At present, infusion therapy, as an important means of replenishing body fluids and an effective measure to provide various nutrients in the body, is a necessary means of clinical treatment. But for many years, in clinical treatment, transfusion has been facing potential dangers, that is, blood pollution, and insoluble particles in veins seriously endanger human health. [0003] During the infusion process using an ordinary filtered infusion set, the insoluble particles in the drug enter the human body during the infusion. When the insoluble particles reach a certain amount, it is easy to induce cardiovascular and cerebrovascular diseases and pulmonary embolism. In mild cases, it may cause blood Circulatory disorder, severe cases lead to organ necrosis, serious life-threatening. Therefore, t...
