Abstract

The invention belongs to the technical field of medical apparatus, and in particular relates to a precision filtration infusion needle. A connecting base, which is provided with a protective sheath, is arranged at one end of the precision filtration infusion needle; an infusion pipeline and a precision medicine liquid filter are arranged in the middle of the precision filtration infusion needle; and components of the infusion needle are arranged at the tail end of the precision filtration infusion needle. The invention aims at providing a precision filtration infusion needle which is capable of filtering infused medicines by itself.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a precision filter transfusion needle. Background technique [0002] Existing intravenous infusion needle itself has no filtering function, and the method of use is generally to be used in conjunction with an infusion set and a syringe. When it is used in conjunction with an infusion set, the infused drug is completely filtered by the liquid filter on the infusion set; when it is used in conjunction with a syringe, the infused drug cannot be filtered, resulting in insoluble in the drug Particles enter human blood vessels and form a large amount of residue, which brings certain risks to patients in clinical use, which has limitations in use. Contents of the invention [0003] The object of the present invention is to provide a precision filter transfusion needle which can filter medicine itself. The precision filter infusion needle is equipped with a precis...
