In-vivo temperature control system

Abstract

An in-vivo temperature control system capable of adjusting a temperature in a biological lumen by continuously or intermittently discharging a liquid into the biological lumen such as the esophagus and collecting and eliminating the released liquid from a living body to the outside. The in-vivo temperature control system includes: a first tube having a first channel; a second tube having a second channel; a liquid storage section; a liquid injection pump for supplying the liquid from the liquid storage section to the first channel and discharging the liquid into a living body via the first channel; a liquid suction pump for collecting the liquid in the living body via the second channel; and a third tube provided with a third channel, connected at one end to the liquid suction pump, and opened to the outside at the other end. The liquid suction pump switches operation between discharge operation for discharging the liquid.
