Wound drainage - quality from innovation

Wound drainage systems are frequently beset with problems that render them hazardous and inefficient. Problems with conventional wound drainage systems:

  • Contamination of wound drain during placement
  • Opening of system in some cases with attendant risk of contamination
  • Loosening of connection and risk of secondary infection
  • Insufficient drainage action due to insufficient vacuum or excessive vacuum suction affecting vital tissues
  • Secondary haemorrhaging and oedemas after the drain is removed

A closed system is the logical consequence resulting from a practical analysis of these problems. DRAINTEC®- The closed wound drainage system. The single-use components are not replaced from placement to removal of the wound drain. This is made possible by the special placement systems with the single-use wound drainage set and the reusable DRAINTEC® lancet. The drain is placed in the wound from the outside under visual control.

There is no risk of unintentional opening of the system, because there is no connective juncture between the drain and the drainage system. This automatically leads to a simplified and reliable ward procedure.

During the important post-operative phase, the amount of secretory matter produced by the wound controls the suction rate - i.e. THE WOUND CONTROLS THE DRAINAGE DEVICE.

Use of the DRAINTEC® device does not restrict mobility, i.e. patients can be mobilized at any time. Setting the required level of optimally gentle vacuum at various intervals following surgery.

It is now possible to use only one small-diameter drain (12CH) due to the optimized drainage action. The larger-diameter drains often required by other systems due to insufficient drainage action result in follow-up problems, such as enlarged entry openings, resulting in a risk of infection, disturbed wound healing, secondary haemorrhaging and oedemas. Scientific evidence shows that secondary haemorrhaging following hip surgery involves an increased risk of chronic infection.
