Abstract

The utility model discloses a urine drop counter which consists of a catheter and an electric key. The urine drop counter is characterized in that the electric key is composed of two conductive wires, wherein, one conductive wire consists of a section of inclined part and a section of vertical part, the other conductive wire consists of a section of inclined part, the two conductive wires present a Y-shape, a fracture is formed at the cross location of the Y-shaped conductive wire, and the catheter drips urine drops to the fracture. Destroying the surface tension of the urine drops flowing through the electric key and guiding the urine drops to drop along the vertical part, the vertical part of the Y-shaped electric key is hard to be influenced by the liquid surface tension and causes the urine drops hard to stay on the electric key when urine drops flow through the electric key, thereby reducing the drop-counting error and improving the accuracy of experimental data.
