The invention refers to medicine, namely to a device for drainage of wounds in the postoperation period. Summary of the invention consists in, that the drainage device is an elastic tube, containing drainage holes and regulating flexible draught consisting of threads passing through a channel and a proximal-facing hole, the drainage holes of which are identic and made in the form of longitudinal slats executed into the elastic tube wall. The slots are situated in the elastic tube distal part sectors, equidistant placed around the circular edges, the free thread ends of the flexible draught being fixed to the elastic tube wall in each sector distal part in two diametrically opposite points. On the flexible draught threads close by the tube proximal hole there are made nodes and in the outlet of the threads through the tube proximal hole there are formed loops, on the tube proximal end there are executed slots for nodes fixation.Claims: 1Fig.: 4 |
