Abstract: A connector includes a first port, a second port, a first sealing member and a second sealing member. The first port and the first pipe sleeve portion are connected with each other such that at least a part of the first port and at least a part of the first pipe sleeve portion engage with each other by fitting and overlap with each other, and a first sealing member is positioned between two overlapping portions. The second port and the second pipe sleeve portion are connected with each other such that at least a part of the second port and at least a part of the second pipe sleeve portion engage with each other by fitting and push each other, and a second sealing member is positioned between two pushing portions.

Abstract: A connection unit for air feeding tube is a connection unit to which an air feeding tube is connectable and fixable and which includes: a first pipe having an opening through which gas from the air feeding tube flows in; a second pipe that is configured to be arrangeable substantially parallel to a surface of a bed used in an examination, and includes an opening through which the gas flows out; and an air feeding flow path which is formed to include the two openings and through which the gas is fed. When the air feeding tube is fixed to the connection unit for air feeding tube and is used, a part of the air feeding flow path for the gas is formed so as to pass through an area located at a position opposite to a gravitational direction with respect to a central axis of the second pipe.

Abstract: An insufflation device includes: a gas feeding conduit through which a gas is supplied to a body cavity of a patient; a first open/close valve mounted on the gas feeding conduit, the first open/close valve being an electromagnetic valve configured to control a flow rate of the gas flowing through the gas feeding conduit by pulse width modulation; and a controller, the controller being configured to: detect a current value of a current which flows through the first open/close valve; calculate a resistance value of the first open/close valve based on the current value; determine a duty ratio of a pulse signal applied to the first open/close valve based on the resistance value and a target gas feeding flow rate of the gas supplied to a body cavity; and supply the pulse signal, an effective voltage of which is adjusted, to the first open/close valve.

Abstract: A gas feeding apparatus includes first and second temperature sensors for measuring a temperature of an atmosphere that are disposed in a housing. The apparatus may also include a panel, a protrusion protruding forward from the panel, a first opening provided in the panel in a vicinity of the first temperature sensor, and a second opening provided in the panel in a vicinity of the second temperature sensor. The first temperature sensor and the second temperature sensor are separated by a predetermined distance in a horizontal direction and disposed below the protrusion.

Abstract: An insufflation system includes an insufflation device for supplying gas to a body cavity, and a suction device for suctioning the gas from the body cavity through a suction conduit at a suction flow rate. The insufflation device includes a flow rate sensor for measuring a gas feeding flow rate, a pressure sensor for measuring body cavity internal pressure, a first on-off valve for controlling the gas feeding flow rate, a second on-off valve for opening and closing the suction conduit, and a processor for opening the second on-off valve and controlling the first on-off valve to feed the gas at an amount when a first target gas feeding flow rate calculated from difference between the body cavity internal pressure and insufflation target pressure is lower than a threshold flow rate, the amount being obtained by adding the suction flow rate to the first target gas feeding flow rate.

Abstract: An insufflation device includes: a gas feeding conduit for feeding a predetermined gas which is fed from a gas supply source into a body cavity; and a processor. The processor measures a gas feeding time period until a predetermined amount of the gas is fed according to a set pressure, measures a pressure in the body cavity, calculates a gas discharging time period based on the set pressure and a measurement result of the measured pressure; and adjusts a gas feeding flow rate of the gas according to a difference between the measured gas feeding time period and the calculated gas discharging time period.
