Abstract
The utility model discloses a disposable liquid-stopping flow-slowering transfusion device comprising an upper dropping funnel and a lower dropping funnel, and a transfusion guide pipe connected with the lower dropping funnel, wherein a liquid-stopping device is arranged in the lower dropping funnel. A liquid-stopping diaphragm of the liquid-stopping device is attached to an inner side of the bottom of the liquid-stopping device during working. At least one groove is arranged on the inner wall of the bottom of the liquid-stopping device, wherein the groove comprises an upper port and a lower port. The section size of the upper port is larger than that of the lower port. When the liquid-stopping diaphragm is attached to the inner wall of the bottom of the liquid-stopping device, medical liquid in the lower dripping funnel flows through the upper port an the lower port in sequence and into the transfusion pipe. As the groove is arranged on the inner wall of the bottom of the lower dropping funnel, the medical liquid left in the lower dropping funnel can enter from the upper port of the groove and slowly flow into the transfusion guide pipe from the lower port of the groove when the liquid-stopping diaphragm of the liquid-stopping device is attached to the inner wall of the bottom of the liquid-stopping device. Air enters to supplement when the lower dropping funnel is empty. Therefore, the medical liquid in the transmission guide pipe continues to flow into human bodies slowly, time of medical liquid dropping is prolonged, and blood return is prevented.
