Abstract

The invention provides a dual-valve purification vein infusion device provided with a filtering elastic valve and an elastic buoyant valve. An upper infusion tube is arranged on the outer upper end of the outer housing of a drip cup, a puncture needle is arranged on the upper end of the upper infusion tube, an elastic valve cylinder connected to an elastic valve base is arranged in the outer housing of the drip cup, a dripping tube observing infusion speed is arranged on the inner upper end of the elastic valve cylinder, the elastic valve base is arranged on the upper middle portion of the elastic valve cylinder, an elastic valve liquid inlet hole is formed in the middle part of the elastic valve base, and a cone gear-shaped elastic valve is arranged on the lower end of the elastic valve liquid inlet hole. The elastic valve base, a cross base and the elastic valve cylinder are cast integrally to form an elastic filtering and purification combination, the elastic filtering and purification combination is fixedly arranged in the drip cup and fixed integrally with the drip cup, and a lower infusion tube is arranged on the lower end of the drip cup. When the vein infusion device is used, a seal film is uncovered, and a scalp intravenous needle is connected to and arranged on the inner end of an infusion connector with screw threads, so that infusion is achieved.

Description

technical field [0001] The invention relates to an intravenous transfusion device, specifically a dual-valve purifying intravenous transfusion device provided with a filter screen, an elastic valve device and an elastic buoyancy valve. Background technique [0002] Intravenous infusion set is an important equipment in clinical medical treatment, which plays a major role in the treatment and rehabilitation of patients. Due to the defects of structure and design, the intravenous infusion set currently used has the following shortcomings in clinical use. One is that the infusion patient lies on his side or When the affected limb is raised, it is easy to cause blood reflux in the infusion needle; the second is that during infusion, if the liquid medicine in the infusion bottle drips and the infusion bottle is not replaced in time, the dropper will enter the air or the blood will return. When the infusion bottle is replaced and the infusion is continued, the air in the infusion t...
