Description
Technical field
This utility model relates to a kind of medical supplies, the closed negative pressure drainage device of especially a kind of surgery.
Background technology
The notion of negative-pressure sealed drainage technology (vacuum sealing drainage/VSD is called for short the VSD technology) the earliest by German ULM doctor Fleischmann of university in initiative in 1992, and form six and take turns blank, be used for the drain of extremity wound surface.1997, Morykways etc. discovered that this device can promote the wound surface local blood circulation, promoted post bud tissue to generate, and reduced tissue bacterial content, improved flap or free skin-grafting survival rate.Confirmation such as Moues afterwards, the negative-pressure sealed drainage technology is compared with traditional moistening dressing wrapping, significantly shortens wound healing time.Fbaian compares more with hyperbaric oxygentherapy through experimental study discovery negative pressure drainage can promote granulation tissue hyperplasia; Couttefangeas finds that the cell that soaks on the adjuvant of wound filling is mainly the granulocyte composition, and CD4 (+) function T cell can promote the cleaning in the wound surface, and good microenvironment is provided.Labanaris etc. discovered that VSD can promote the hypertrophy of wound surface surrounding tissue lymph pipe network in 2009.More and more scholars has confirmed VSD Clinical application effect through a large amount of research and clinical practice, and its theoretical research is updated, and states such as Germany in 2003, Austria include this technology in wound treatment guide.
The negative-pressure sealed drainage technology is meant with the polyethylene ethanol aquation Sargassum salt foam dressing (VSD adjuvant) that contains negative-pressure drainage tube; Cover or fill the wound surface of skin, soft tissue defects; The biological semipermeable membrane of reuse seals it; Make it become a confined space, connect negative pressure source to negative-pressure drainage tube at last, promote a kind of brand-new Therapeutic Method of wound healing through controllable negative pressure.In China VSD technology adaptable across fields such as traumatology department, orthopaedics, department of general surgery, Department of B urns.
Existing VSD technology basic configuration comprises negative pressure source (comprising central negative pressure device or negative pressure drainage vessel that medical attractor, hospital use); Negative-pressure drainage tube, polyvinyl alcohol foam or other medical porous foam, sponge or gauze (being called for short porous dressing), the breathable films that can glue card sealing usefulness, joint (comprising two pass joints, three way cock or multiple-pass joint), drainage container etc.
The VSD technology is the product that traditional negative pressure drainage method is combined with closure dressing, and it produces machinery and biological effect through forming negative pressure at wound surface, promotes wound healing.Therefore must use special-purpose wound surface to fill dressing, existing wound surface is filled the dressing of dressing porous, and it requires inside to keep clear; To guarantee that the tissue that vacuum suction goes out can be by normal sucking-off, common used material is a polyvinyl alcohol, and requires the foam micro-pore diameter at 0.2-1.0mm; And the polyvinyl alcohol cost is high, and manufacturing process is complicated, mainly depends on import at present; Simultaneously the required quantity of each patient treatment is more, causes this type of Therapeutic Method cost very high, has increased heavy financial burden to the patient.Therefore, a kind of substitute products cheaply of exploitation are task of top priority.
On this basis, this utility model people utility model the closed negative pressure drainage of a kind of surgical wound fill dressing and method for preparing with wound surface, its wound surface is filled dressing and is substituted polyvinyl alcohol with vegetable sponge; Reduced cost, still, it is fixed that the wound surface that the closed negative pressure drainage of this surgical wound uses is filled dressing; Disposable, it is filled dressing apply on wound, if want to observe the healing state of skin; Tear the filling dressing of wound surface; After having observed, need to change and fill dressing, fill dressing and cannot use repeatedly; Secondly, employing be active mechanical negative pressure, carry inconvenience; Once more, vegetable sponge is filled dressing in use, is prone to be corroded.
