Described is a barrier application device comprising a handle, an introducer assembly slidably and rotatably coupled to the handle, a beam assembly coupled to a distal end of the handle, and a flag coupled to the beam assembly. A method of using a barrier application device comprises providing a device comprising a handle, an introducer assembly slidably and rotatably coupled to the handle, a beam assembly coupled to a distal end of the handle, and a flag coupled to the beam assembly, and placing a barrier on the flag, sliding the introducer assembly along the handle from a retracted position to an extended position at least partially covering the beam assembly, and rotating the handle relative to the introducer assembly until the flag and the barrier are wound around the beam assembly.本發明係描述一屏障施用裝置,其包含一握柄,一被可滑動地且可旋轉地耦合至握柄之導入器總成,一被耦合至握柄的一遠端之樑總成,及一被耦合至樑總成之標旗。一使用一屏障施用裝置之方法係包含提供一裝置,該裝置包含一握柄,一被可滑動地且可旋轉地耦合至握柄之導入器總成,一被耦合至握柄的一遠端之樑總成,及一被耦合至樑總成之標旗,以及使一屏障放置於標旗上,使導入器總成沿著握柄從一縮回位置滑動至一至少部份地覆蓋樑總成之延伸位置,及使握柄相對於導入器總成旋轉直到標旗及屏障捲繞於樑總成周圍為止。
