The present invention provides a safe infusion set and a preparation method thereof. The infusion set comprises a drip chamber and an infusion tube, both made of polyurethane/polyvinyl chloride double-layer composite material. The inner surface layer of the polyurethane/polyvinyl chloride double-layer composite drip chamber is a polyurethane layer, and the outer surface layer is a polyvinyl chloride layer. The polyurethane/polyvinyl chloride double-layer composite material is prepared by co-extrusion blow molding, and the polyurethane/polyvinyl chloride double-layer composite infusion tube is prepared by co-extrusion. The safe infusion set avoids the disadvantages of PVC infusion sets such as drug adsorption and contamination of liquid medicine by small molecules such as plasticizers, has excellent mechanical properties, is easy to bond and assemble, and features low raw material cost.
