The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further.
As shown in Figure 1: a kind of two slotting transfusion device with screw thread liquid medicine filter, it comprises the first feed liquor mechanism, the second feed liquor mechanism, dropping funnel 10, liquid medicine filter 6 and transfusion needle 7, described the first feed liquor mechanism and the second feed liquor mechanism are connected to dropping funnel 10 liquid feeding ends by three-way piece 4, dropping funnel 10 liquid outlets are connected with liquid medicine filter 6, and liquid medicine filter 6 liquid outlets are threaded with transfusion needle.Operate for the ease of medical personnel, this utility model also is provided with the 3rd flow regulator 9 between dropping funnel 10 and liquid medicine filter 6, concrete is that the 3rd flow regulator 9 connects respectively the liquid outlet of dropping funnel 10 and the liquid feeding end of liquid medicine filter 6, and control enters the medicinal liquid flow of liquid medicine filter 6.
