Description
Technical field
The present invention relates to the et al. Ke negative pressure closed drainage device that a kind of cloverleaf pattern can be extracted, be particularly useful for the wound surface such as closed large area soft tissue defects, deep infection wound surface, subcutaneous potential lacuna, avulsion injuries, large area liquefaction of fat.
Background technology
1992, negative pressure closed drainage device (VacuumSealingDrainage is called for short VSD) was first used for the treatment of extremity soft tissue wound surface by the traumatology department of German ULM university doctor Fleischmann etc.1994, Qiu Huade etc. took the lead in introducing this Novel drainage technology and device at home.Through the clinical practice observation of curative effect of nearly 20 years, negative pressure closed drainage device became one of standard care pattern of these wound surface of process, and instead of the various drains of traumatology department, orthopaedics, department of general surgery, thoracic surgery and Department of B urn etc. gradually.Negative-pressure sealed drainage technology is also applied to spinal surgery gradually in recent years.Zehnder etc. once reported that negative-pressure sealed drainage technology was also used successfully to spinal column postoperative wound infection.
The medical foam dressing that its formation of existing negative pressure closed drainage device is made up of (1) macromolecule polymeric material polyvinyl alcohol, outward appearance is just as sponge, white, nontoxic, immunologic incompetence, corrosion-resistant, there are fabulous adsorptivity and water penetration, quality is soft, and tension stress is strong, and original packing is 15cm × 10cm × 0.9cm, prune according to wound surface size during use, post in wound surface, edge can be fixed by interrupted suture number pin, by the silica gel tube of two on foamed materials from drawing away from puncture in the about 2 ~ 4cm normal subcutaneous tissue of wound surface/chamber or " mesentery method " extraction.(2) wound closure/chamber: by clean for wound surface surrounding skin dry, pastes close whole wound surface to wound surface edge about 3 ~ 4cm scope with biological permeable membrane (it has good breathability, energy waterproof, and can prevent bacterial invasion, to no skin irritation).(3) connect negative pressure: drainage tube is connect negative pressure bottle, central negative pressure attracts or electronic attraction, adjustment negative pressure to 60 ~ 80kPa, and shrink with dressing and diminish, matter is pliable and tough, has liquid drain to go out for degree.The weak point of existing negative pressure closed drainage device is: (1) medical foam dressing is designed to rectangle, inside only has two silica gel tubes, though can cutting, but still be suitable for complicated shape wound surface and wound chamber, deep, and drainage tube and syringe pipe are very easily destroyed after cropped thus lose its effect; (2) medical foam dressing edge and inside are without silica gel developing line, after being placed in the wound surface such as large area soft tissue defects, deep infection wound surface, subcutaneous potential lacuna, avulsion injuries, large area liquefaction of fat, and integrity when cannot guarantee that it is extracted; (3) design of medical foam dressing rectangle and the inner two silica gel tube line space design of medical foam dressing are comparatively greatly, and this design is unfavorable for that deep is implanted and later stage Wicresoft's taking-up.
