Abstract: A medical support device includes a processor used for an endoscope apparatus including an endoscope that images a luminal organ and a treatment tool that is energized in a state of being in contact with a treatment target part included in the luminal organ to cut the treatment target part. The processor is configured to output permission and non-permission information indicating whether or not the energization is permitted. Whether or not the energization is permitted is determined on the basis of a captured image that has been obtained by imaging the luminal organ with the endoscope and that includes the treatment tool.

Abstract: There is provided an insufflation system and an insufflation apparatus which can prevent a pressure inside a lumen from rapidly increasing and can achieve operability matched to a sense of an operator. When the operator operates an air/water supply button of the endoscope, the gas is insufflated into a gastrointestinal tract of a patient through an internal conduit of the endoscope (manual insufflation). Meanwhile, the insufflation apparatus is connected to an insertion assisting tool which guides the endoscope into the gastrointestinal tract. When the insufflation apparatus automatically performs insufflation, the gas is intermittently insufflated into the gastrointestinal tract of the patient so as to maintain the pressure inside the gastrointestinal tract at the set pressure (automatic insufflation). The average flow rate of the gas in the automatic insufflation is set to be less than or equal to the insufflation flow rate in the manual insufflation.

The insufflation apparatus is connected to an endoscope and an insertion assisting tool which guides the endoscope into the gastrointestinal tract. Carbon dioxide can be insufflated into a gastrointestinal tract of a patient through an internal conduit of the endoscope according to an operator's operation (manual insufflation). When the operator instructs the insufflation apparatus to perform the automatic insufflation, carbon dioxide is intermittently insufflated into the gastrointestinal tract through the insertion assisting tool so as to make the pressure inside the gastrointestinal tract become a set pressure (automatic insufflation). The insufflation flow rate of the manual insufflation is switched between the high flow rate and the low flow rate according to ON/OFF state of the automatic insufflation.
