Negative-pressure sealed drainage technology (VSD) is in 1992 by traumatology department of ULM, Germany university Fleischmann et al.
It is pioneering, earliest i.e. applied to the treatment of orthopedic injury.Can be used for various soft tissue contusions, defect or infection, big hemotoncus or
Hydrops, osteofascial compartment syndrome, open fracture are possible or concurrent infection person, articular cavity infection need incision and drainage person, acute and chronic
Skin-grafting area etc. after osteomyelitis needs Fenestration drainage person, skin grafting.The interior polyethylene alcohol aquation seaweed salt containing drainage tube of VSD
Foam dressing (VSD auxiliary materials) to cover or fill the surface of a wound of skin, soft tissue defects, then with biological semi-permeable film seals it
It closes, becomes a confined space, drainage tube is finally connected negative pressure source, effectively excludes the purulence in body cavity, organ or tissue
Property the harmful substances such as hydrops, slough, foreign matter, the blood of abnormal accumulation and digestive juice, can lavation VSD shield traumatic materials can lead to
The substances such as perfusion duct injection antibiotic, physiological saline are crossed, sterilization, flushing are played the role of.
The common VSD of Present clinical protects traumatic material by monoblock foam type polyethylene alcohol aquation seaweed salt foam dressing (PVA
Foam) and be inserted into foamed material in more side openings conduction conduits or special drainage catheter composition.The monoblock foamed material is close to create
The case where causing that the surface of a wound can not be observed in the case where not removing VSD behind face, may cause cannot be timely when the surface of a wound deteriorates
It was found that influencing therapic opportunity；In addition may also result in cannot remove VSD when the surface of a wound improves in time, and VSD is caused excessively to use.
