Double-sided filtering precise-filtering transfusion device

The utility model relates to a double-sided filtering precise-filtering transfusion device, which belongs to the medical appliance for clinical vein transfusion, and comprises a liquid medicine filterwith the upper and the lower ends being provided with a liquid inlet and a liquid outlet and with two sides being provided with an air exhaustion port, and is characterized in that a filtering film fixed beam is transversely arranged on the upper section of the liquid medicine filter to correspond to the liquid outlet, a filter film is respectively arranged between two sides of the filtering filmfixed beam and the two sides of the corresponding liquid outlet, and the two filtering films divides the liquid outlet and the inner cavity of the liquid medicine filter into two independent cavities. By adopting the double-sided filtering, the filtering area of the filtering film is increased, but the size of the liquid medicine filter is not increased, so that the filtering area can be increased on the premise that the
