The present invention relates to an apparatus for sensing the level of an IV and an operation method thereof. The apparatus automatically monitors the state of administration of an infusion which includes blood, a nutritional supplement, a therapeutic agent, an IV, etc. and is inserted in a container, in the case of directly injecting the infusion into the blood vessel of a patient through a tube and an injection needle in a hospital. Accordingly, in the case of the completion of administration, interruption of supply, or supply failure, a warning signal is generated to allow a person to quickly take follow-up measures, thereby protecting the patient, preventing medical accidents, and enhancing the reliability of medical services. The apparatus for sensing the level of an IV comprises: a housing part which is attached to one part of an IV tube receiving an IV by an opening and closing device, and is fixed to surround the IV tube or detached a level sensing circuit part which is embedded in the housing part, monitors the state of supply of the IV in the IV tube by at least one means among heat, light, and capacitance, stops the supply of the IV when it is determined that there is an interruption of supply as a result of monitoring, outputs the result of monitoring into a multimedia signal, includes a serial number and location information in the result of monitoring, and transmits the result of monitoring to a designated person and a demanding person by wireless and an infusion supply stopping part which is embedded in the housing part, and physically compressing one side of the IV tube so that the IV tube supplies the IV or stops the supply thereof by the control operation of the level sensing circuit part.COPYRIGHT KIPO 2016본 발명은 병원에서 환자에게 혈액, 영양제, 치료제, 링거액 등이 포함되는 수액을 용기에 주입된 상태로부터 튜브와 주사바늘을 통하여 환자 혈관에 직접 주사하는 경우 수액의 투여 상태를 자동 감시하여 투여가 완료되었거나 공급이 중단되거나 공급 장애가 있는 경우 경고신호를 발생하여 신속한 후속조치가 이루어지도록 하므로 환자를 보호하면서 의료사고를 예방하고 의료서비스의 신뢰도를 높이는 링거수액 레벨 센싱 장치 및 그 운용방법에 관한 것으로
