Abstract

The invention discloses a precise liquid medicine filter, which belongs to medical instruments and structurally comprises an upper cover, a lower cover, a liquid inlet nozzle and a liquid outlet nozzle. The upper cover is fastened with the lower cover, an upper cover ring is arranged on the inner side of the upper cover, a water flowing hole is arranged on the upper cover ring, the liquid inlet nozzle and the liquid outlet nozzle are respectively arranged at two ends of the lower cover, a plurality of exhaust holes are arranged on the upper cover, a liquid collecting groove is arranged in the middle of the lower cover, the liquid outlet nozzle is communicated with the liquid collecting groove, the liquid collecting groove is a U-shaped groove, and a plurality of bumps which are arrayed like a tree are disposed on the lower cover at two ends of the liquid collecting groove. The precise liquid medicine filter has the advantages that bubbles generated in a transfusion process are discharged so as to realize safety transfusion, a space between the upper cover and the lower cover is enlarged, the difficult problem that the bubbles are detained on a liquid inlet level and a liquid outlet level of the precise liquid medicine filter during usage is resolved, liquid medicine guiding is fast, exhaust speed is increased, and the like.

Description

technical field [0001] The invention relates to a medical device, in particular to a precision filter for medicinal liquid. Background technique [0002] The insoluble particles generated during the operation may be brought into the liquid medicine by the needle infusion, and inadvertently brought into the blood vessels of the human body through the infusion, and there is no entry, which becomes a long-term latent hazard. Running, waiting for an opportunity to cause various large and small diseases, the hidden danger is great. People have gradually realized this, and products with corresponding structures have been launched one after another. However, in the precision filter of medicinal liquid used in medical treatment, air is often generated in the medicinal liquid during clinical infusion. Some air bubbles are attached to the wall of the infusion hose, and some enter the human body with the medicinal liquid. After entering the human body and circulating to the lungs, it...
