Description

An improved negative pressure drainage and wound protection device that can observe the wound

technical field

The utility model relates to the technical field of medical appliances, in particular to an improved negative pressure drainage and wound protection device capable of observing wounds.

Background technique

Vacuum sealing drainage technique (VSD) was pioneered in 1992 by Fleischmann et al. in trauma surgery at the University of Ulm, Germany, and was first applied to the treatment of orthopedic trauma. It can be used for various soft tissue contusions, defects or infections, large hematoma or effusion, osteofascial compartment syndrome, patients with possible open fractures or co-infection, patients who need incision and drainage for joint cavity infection, and patients who need incision and drainage for acute and chronic osteomyelitis. Window drainage patients, skin grafting areas after skin grafting, etc. VSD uses polyvinyl alcohol hydrated seaweed salt foam dressing (VSD accessories) with a drainage tube to cover or fill the wounds with skin and soft tissue defects, and then seals them with a biological semipermeable membrane to make it a closed space. Finally, connect the drainage tube to a negative pressure source to effectively remove harmful substances such as purulent effusion, necrotic tissue, foreign matter, abnormally accumulated blood and digestive juices in body cavities, organs or tissues. Antibiotics, saline and other substances are injected into the holes to play the role of sterilization and flushing.

The currently commonly used VSD wound protection materials in clinical practice consist of a monolithic foamed polyvinyl alcohol hydrated seaweed salt foam dressing (PVA foam) and a drainage catheter with multiple side holes or a special drainage catheter inserted into the foam material. When the whole piece of foam material sticks to the wound surface, the situation of the wound surface cannot be observed without removing the VSD, which may lead to the inability to detect in time when the wound surface deteriorates and affect the timing of treatment; in addition, the VSD may not be removed in time when the wound surface improves , leading to overuse of the VSD.
