The invention discloses a medical perfusion type irrigator, belonging to the technical field of medical equipment. The medical perfusion type irrigator comprises a microprocessor module and a peristaltic pump, wherein the microprocessor module sends signals to the peristaltic pump to control the liquid outlet pressure and liquid outlet flow speed of the peristaltic pump; the microprocessor module is connected with a keyboard module, a pressure sensor, a flow speed sensor and a display module. The medical perfusion type irrigator disclosed by the invention can provide irrigation fluids with two flow speeds and four pressures, and can accurately control the temperature of the irrigation fluids and realize continuous irrigation as well as intermittent irrigation; with human-machine interaction, the irrigator is friendly and convenient to operate; moreover, in a special situation, the irrigator can give an alarm through sound and light to remind the medical personnel to handle exception in time. The medical perfusion type irrigator disclosed by the invention is applicable to multiple operations and the irrigation of multiple operative sites or tissues.
