<p>The syringe is used in general surgery and in practically all operative processes for effecting vaccum drainage (Redon drainage) of wounds. It is easily and conveni-ently handled under all conditions avoiding any complex aspiration devices and setting prerequisites for the early movements of the patient. The syringe is disposable and is of the Louere type. It has cylindrical body (1) and piston (2). Several circular locking projections are fabricated on the inner surface of the cylindrical body (1) enabling the movement of piston (2) only in the drawing position. 1 claim, 1 figure</p> |
