Abstract
A pressure adjustment unit of a hemostatic instrument includes a main container portion connected to a side of a balloon and an auxiliary balloon serving as an expansion member. The main container portion has, for example, air passing holes for permitting a portion of a fluid (air) to be expelled. A sliding member is installed at the main container portion and is movable along the main container portion from a state in which the air passing holes of the main container portion are blocked to a state in which one or more of the hole are open, and a moving body movable inside the main container portion to successively block the air passing holes opened by moving the sliding member.
