<p>Wound drainage which comprises a cylinder (10) arranged as a suction chamber, with a piston (17) displaceable therein. The cylinder is capable of being connected via a stop-valve (13) to a drainage catheter (15) at one end thereof, whilst an elastic strand (19) which is connected with the piston is withdrawn through the other end of the cylinder. The strand can be locked in the desired withdrawn position by means of a locking device (23) which prevents the movement of the strand into the cylinder. </p> |
