Abstract

The invention discloses a vein infusion device provided with an elastic buoyant valve and a filtering and purification device. 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, a buoyant valve cylinder connected to a buoyant valve base is arranged in the outer housing of the drip cup, a dripping control tube observing infusion speed is arranged on the inner upper end of the buoyant valve cylinder, the buoyant valve base is arranged on the upper middle portion of the buoyant valve cylinder, a buoyant valve liquid inlet hole is formed in the middle part of the buoyant valve base, and a cone gear-shaped buoyant valve is arranged on the lower end of the buoyant valve liquid inlet hole. The buoyant valve base, a cross base and the buoyant valve cylinder are cast integrally to form a buoyant filtering and purification combination, the buoyant 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 in use, 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 double-valve intravenous transfusion device provided with an elastic buoyancy valve and a filtering and purifying device. 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 tube will enter t...
