Description
Technical field
The utility model relates to a kind of medical instrument, especially a kind of trauma surface infestation treatment auxiliary instrument, specifically
It is a kind of for carrying out the drainage of negative pressure continual rinsing to the surface of a wound, is discharged in time with improving surface of a wound necrotic tissue, the surface of a wound is promoted to accelerate
The Wound-surface negative pressure irrigation and drainage device of healing.
Background technique
It is initiated it is well known that VSD technology is equal to 1992 by German ULM university Fleischman, in recent years domestic scholars
It is widely used in the drainage of the various surface of a wound, this technology is widely used in orthopaedics, department of general surgery.The VSD mechanism of action is: (1) closing
It is maintained the high negative pressure as drainage power, while also making to be drained area and be isolated from the outside world, is effectively prevented pollution and friendship
Fork infection；(2) high negative pressure closing can make to be drained area with the diffusate of the continuous drainage surface of a wound, necrotic tissue and bacterium, toxin etc.
Inside reach " nil product is poly- ", the surface of a wound can obtain clean environment quickly；(3) increase surface of a wound blood supply, improve surface of a wound microcirculation, promote meat
Bud tissue growth.VSD can be remarkably reinforced in wound margin tissues' high dermis vascular endothelial cell, fibroblastic proliferation and micro- blood
Pipe density；(4) activity for adjusting gelatinase in the surface of a wound improves microcirculation in wound base, inhibits the degradation of collagen and gelatin, promotes wound
The healing in face；(5) mitigate and create all oedema, reduce vasopermeability.VSD by enhancing the peripheral termination of nerve secretion Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH2 with
And calcitonin gene-related pepide expression, the expression of endogenous epithelical cell growth factor is influenced, there is apparent wound healing
Effect.Currently, for negative-pressure irrigation drainage device have the disadvantage in that 1. currently on the market finished product VSD it is expensive, and
It is not accepted extensively by basic hospital and family numbers of patients；2. it is high replacement installation cost when plugging and flushing liquor extravasation occur；3. because
The device is expensive and can not continue to use so limit routine observation of the clinic to the surface of a wound and assessment after dismantling；4. bulk is bad
Dead tissue can not attract discharge by timely, and the sucker space that suction tube is connected is blocked compared with little Yi by necrotic tissue.
Utility model content
