The invention discloses an anesthesia depth monitoring device for an anesthesiology department. The device comprises a support box and a charger, a capacitor and a brainwave detector which are arranged on one side inside the support box, the output end of the charger is electrically connected with the input end of the capacitor, a first threading pipe is arranged on one side of the capacitor, one end of the first threading pipe penetrates through the support box and extends to the outer side of the support box, a fixing plate is arranged at the end, located outside the support box, of the first threading pipe, the capacitor can be charged through the charger, discharging is conducted through the capacitor, nerves of a patient are stimulated through a current stimulating plate, brainwaves of the patient can be detected through the brainwave detector, and detection is conducted more accurately. The anesthesia depth monitoring device for the anesthesiology department is simple in structure and convenient to operate, not only can anesthetized nerves of the patient be stimulated, but also the response of the brainwaves can be detected accurately, and the anesthesia of the patient is monitored more conveniently.
