Abstract
A cloverleaf-shaped vacuum sealing drainage device for being implanted into a body and capable of being pulled out comprises medical foam dressing. The medical foam dressing comprises one or two or three blades and a blade handle converging with the roots of the one or two or three blades. A drainage tube and a flushing tube are arranged in each blade, one end of the drainage tube at the top end of the blade is connected with a suction cup device, and the periphery of the medical foam dressing, the drainage tubes and the flushing tubes are coated with silicon gel developing lines. The processing technology of the cloverleaf-shaped vacuum sealing drainage device is simple, unique design ensures that the whole device is pulled out, and separate control and operation of the drainage tubes and the flushing tubes are convenient. The cloverleaf-shaped vacuum sealing drainage device overcomes the shortcomings and limit that an original vacuum sealing drainage device is only suitable for a wound surface on the surface of the human body, and is inconvenient to arranged in the human body and suitable for popularization. The cloverleaf-shaped vacuum sealing drainage device can greatly reduce pains of long-term dressing changing, fully achieve drainage and reduce iatrogenic infection and work load of physicians.
Description
Technical field
The present invention relates to the body that a kind of cloverleaf pattern can extract and be implanted into negative pressure closed drainage device, be particularly useful for sealing the wound surface such as large area soft tissue defects, deep infection wound surface, subcutaneous potential lacuna, avulsion injuries, large area liquefaction of fat.
Background technology
1992, first German ULM doctor Fleischmann of the traumatology department of university grade was used for the treatment of extremity soft tissue wound surface by negative pressure closed drainage device (Vacuum Sealing Drainage is called for short VSD).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 processing these wound surface, and had substituted gradually the various drains of traumatology department, orthopaedics, department of general surgery, thoracic surgery and Department of B urn etc.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 successfully for 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 softness, tension stress is strong, and original packing is 15cm × 10cm × 0.9cm, when use, prune according to wound surface size, post in wound surface, edge can interrupted suture be counted pin and is fixed, by two silica gel tubes on foamed materials from away from wound surface/chamber approximately in the normal subcutaneous tissue of 2～4cm puncture draw or " mesentery method " draws.(2) wound closure/chamber: by clean dry wound surface surrounding skin, with biological permeable membrane (it has good breathability, can waterproof, and can prevent bacterial invasion, to skin nonirritant) paste seal whole wound surface to wound surface edge about 3～4cm scope.(3) connect negative pressure: drainage tube is connect to negative pressure bottle, and central negative pressure attracts or electronic attraction, adjusts negative pressure to 60～80kPa, shrinks and diminishes with dressing, and matter is pliable and tough, have 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 not suitable for complicated shape wound surface and wound chamber, deep, thereby and drainage tube and syringe pipe are very easily destroyed after cropped loses its effect; (2) medical foam dressing edge and inner without silica gel developing line, is placed in after the wound surface such as large area soft tissue defects, deep infection wound surface, subcutaneous potential lacuna, avulsion injuries, large area liquefaction of fat, integrity cannot guarantee that it is extracted time; (3) the inner two silica gel tube spacing design of the design of medical foam dressing rectangle and medical foam dressing is larger, and this design is unfavorable for that implant in deep and later stage Wicresoft's taking-up.
