The invention provides a maintenance prompter for medical equipment. A sensing device comprises a monitoring end, a wire, a connecting plug, a bonding layer, a temperature sensing chip and a photoelectric sensing chip. A working state detection module and a wireless control module are arranged on a device shell. The working state detection module comprises an information detection unit, an information storage unit, a communication unit and a display unit. The wireless control module comprises a wireless communication module, a smart phone APP module, a central controller and a voice recognition module. The information detection unit sets sensing data of a frequency detection sensing device. Working states, stored in the information storage unit, of all the medical equipment are displayed by the display unit in turn. The smart phone APP side can read detected data and wirelessly control the working states of the medical equipment. The maintenance working efficiency of the medical equipment is greatly improved, and the work intensity of daily maintenance staff is relieved.
