Digital Temperature Control for an Hyperthermic Intraperitoneal Chemotherapy Equipment

This paper presents the design of a digital temperature controller for cytostatic solution used in hyperthermic intraperitoneal chemotherapy (HIPEC). Cytoreductive surgery and HIPEC technique, i.e. Regional chemotherapy using cytostatic drugs at high temperatures of 42-43°C, represents a treatment technique for cancer patients suffering of peritoneal carcinomatosis. The main challenge is to maintain the desired temperature of the cytostatic solution in the intraperitoneal cavity, thus, avoiding local abdominal injuries and systemic hyperthermia. In order to maintain the adequate temperature a digital controller is designed using the Dahlin algorithm, a model based design technique.
