ことができる。``Prior Art and Problems'' As is well known, in surgeries such as open-heart surgery, an extracorporeal circulation blood circuit is connected to the patient, and anesthetic gas is sent to the patient, which also serves as artificial respiration. The main parts of these extracorporeal circulation circuits (including intravenous drip devices), gas supply devices such as artificial respirators, and their control parts are all built into an anesthesia machine (general anesthesia machine), and the anesthesiologist is responsible for Blood circulation volume, drip volume, and gas supply volume are controlled based on urine volume, surgical field bleeding volume, pulse rate, blood pressure rate, etc. Since the display unit for pulse rate and blood pressure required for control is installed near the anesthesia machine or on the anesthesia machine itself, the anesthesiologist can easily read the measured values without leaving the anesthesia machine.

いう問題もある。 On the other hand, when measuring the amount of blood and urine, it is difficult to guide the blood discharged into the surgical field or the urine collected by a suction device to a position far from the patient, so anesthesia The doctor must leave the anesthesia machine and approach the measuring reservoir (blood reservoir, urine bag) installed near the patient to read the amount stored. Therefore, a problem arises in that anesthesiologists cannot concentrate on adjusting the patient's condition using the anesthesia machine. In addition, when measuring urine volume, a nurse reads the urine volume from a urine storage bag placed under the operating table and reports it to the anesthesiologist, but since the bag is located almost on the floor, It is difficult and time-consuming to read, and since the urine storage bag is flexible, it easily deforms, resulting in large reading errors.
