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...
