Detailed Description
The technical features of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
The anti-bubble infusion dropping funnel as shown in fig. 1 and 2 comprises a dropping funnel main body, wherein the dropping funnel main body is provided with an upper part and a lower part: a drip chamber part 1 arranged at the upper part and a filter part 2 arranged at the lower part; the filtering part 2 is provided with a liquid storage cavity 3 communicated with the inner cavity of the dropping funnel part 1, and a liquid medicine filter and an air filter 9 which are arranged at two sides of the liquid storage cavity 3; a liquid medicine flow passage 4 is arranged on the side wall of the liquid medicine filter, and the flow passage is provided with a liquid inlet 5 and a liquid outlet 6; the liquid inlet 5 is arranged above the liquid outlet 6; a liquid medicine filtering membrane 7 is arranged between the liquid inlet 5 of the flow channel 4 and the liquid storage cavity 3; an air filter 9 is arranged on the dropping funnel main body on at least one side of the filtering membrane. As shown in fig. 1, air filters are disposed on both sides of the filtering membrane 7, and air filters are disposed on both sides of the filtering membrane, so that air in the liquid storage chamber 3 and the flow passage 4 can be effectively discharged. As shown in fig. 2, an air filter is provided outside the filter membrane 7.
