Abstract

A detaching tool for a tube for medical treatment includes a body for gripping which has generally a U-shape and is resiliently deformable in an opening-closing direction in a bent portion. A separating member is separably disposed inside the body and the separating member generally forms a C-shape and is adapted to be pressed and closed by the body for gripping when the body for gripping is closed. A tube inserting portion is formed in the body and the separating member so that a tube for medical treatment may be inserted and held therein. First and second stream stopping portions are provided at a corresponding location inside the body and a corresponding location inside the separating member so as to press the pertinent portion of the tube and stop a stream inside the tube when the body is closed. First and second holding portions are provided on the body and the separating member so as to maintain the stream stopping states of the first and second stream stopping portions when the body is closed. A cutter for cutting the tube upon closing of the body is provided between the first and second stream stopping portions. A stopper is provided for preventing the cutter from arriving at the tube for a gripping force of a predetermined value or less.

Dependent claims

A detaching tool for a tube for medical treatment comprising:

a body for gripping which has a bent portion between end portions thereof facing each other and is deformable in an opening-closing direction in the bent portion;
a separating member separably disposed inside said body for gripping, said separating member being adapted to be pressed and closed by said body for gripping when said body for gripping is closed;
a tube inserting portion formed in said body for gripping and said separating member so that a tube for medical treatment may be inserted and held therein;
a first stream stopping portion and a second stream stopping portion provided at a corresponding location inside said body for gripping and a corresponding location inside said separating member so as to press a portion of said tube for medical treatment and stop a stream inside said tube when said body for gripping is closed;
a first holding portion and a second holding portion provided on said body for gripping and said separating member so as to maintain the stream stopping states of said first stream stopping portion and said second stream stopping portion when said body for gripping is closed;
a cutter for cutting said tube for medical treatment including a cutting edge between said first stream stopping portion and said second stream stopping portion when said body for gripping is closed;
and
a stopper for preventing said cutter from arriving at said tube for a gripping force of a predetermined value or less, wherein said stopper comprises a connecting piece connecting the pair of grip portions of said body for gripping together and preventing said grip portions from being closed, and adapted to be broken away when a gripping force exceeding a predetermined value acts thereon.
