Abstract
Disclosed is a fluid viscosity measuring device which can measure the viscosity of a fluid such as blood. The fluid viscosity measuring device of the present invention comprises: a first fluid inlet portion in which a fluid, the viscosity of which is to be measured, is injected, and a second fluid inlet portion in which a reference fluid having a standard viscosity is injected; a connection pipe configured to connect the first fluid inlet portion to the second fluid inlet portion and form a passage for the fluid, the viscosity of which is to be measured, and the reference fluid; a plurality of counting channels in communication with the connection pipe at a predetermined distance to be filled with the two fluids flowing along the passage, respectively; and a boundary surface measuring unit configured to count the counting channels filled with the two fluids, respectively.
