1. A compression device comprising:
a main body portion that is fixable to a biological surface of a living body;
a compression portion configured to compress the biological surface;
a hinge portion that supports the compression portion relative to the main body portion so that the compression portion is rotatable around a rotational axis with respect to the main body portion;
a pressing portion configured to press the compression portion in one rotational direction so that the compression portion rotates in the one rotational direction around the rotational axis, the pressing portion including an inflatable pressing body that is located between the main body portion and the compression portion, the inflatable pressing body including an interior configured to receive fluid to inflate the inflatable pressing body;
a receiving portion configured to receive a tubular member constituting at least a part of a medical device that is positioned in the living body;
a fluid supply tube in communication with the interior of the inflatable pressing body to supply the fluid to the interior of the inflatable pressing body;
the compression portion being configured to compress the biological surface when the compression portion is rotated around the rotational axis in the one rotational direction as a result of the compression portion being pressed in the one rotational direction by the pressing portion;
the compression portion being comprised of an inflatable compression body, the inflatable compression body including an interior configured to receive fluid to inflate the inflatable compression body;
the hinge portion being located between the compression portion and the receiving portion in a cross-sectional view orthogonal to the rotational axis;
the interior of the inflatable pressing body and the interior of the inflatable compression body communicating with each other;
the inflatable pressing body having one side connected to the hinge portion, the inflatable pressing body also having an other side opposite the one side, the fluid supply tube being located at the other side of the inflatable pressing body and extending away from the other side of the inflatable pressing body; and
the fluid supplied from the fluid supply tube being supplied to the interior of the inflatable compression body after passing through the interior of the inflatable pressing body.
