HEMOSTATIC INSTRUMENT

摘要

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.

1. A hemostatic instrument comprising:
a band body configured to be wound and fixed around a region of a limb at which bleeding is to be stopped; an expansion member connected to the band body and possessing an interior, the expansion member being configured to expand when a fluid is injected into the interior of the expansion member to apply a pressure force to the region of the limb for stopping the bleeding in the region of the limb; a connector provided at an end portion of an injection passage for injecting the fluid into the expansion member; and a pressure adjustment unit configured to adjust a pressure of the expansion member that is applied to the region of the limb, the pressure adjustment unit including:
a main container portion comprising a communication port that is connected to and communicates with the inside of the expansion member, the communication port being at one end of the main container portion, the main container portion including a fluid passing hole configured to allow a portion of the fluid in the expansion portion to be released to an outside environment,a sliding member mounted on the main container portion, the sliding member being movable along the main container portion from a closed position blocking the fluid passing hole of the main container portion to an open position that allows the portion of the fluid in the expansion portion to be released through the fluid passing hole to the outside environment, anda moving body positioned within the main container portion, the moving body being movable within the main container portion between a first position at which the moving body blocks the fluid passing through hole so that fluid in the main container is blocked from passing through the fluid passing hole and a second position at which the moving body does not block the fluid passing hole so that the fluid passing hole is open and fluid in the main container passes through the fluid passing hole; the main container portion of the pressure adjustment unit including a force applying means for applying a force to urge the moving body within the main container portion towards the one side at which the communication port is provided.
