Background technology
Negative-pressure sealed drainage technology (vacuum sealing drainage is called for short VSD) is that German ULM Wim doctor Fleischman of university initiated in 1992, and forms theoretical blank, is used for the drain of extremity wound surface; Chinese professor Qiu Huade was applied to department of general surgery with the negative-pressure sealed drainage technology first in 1994, had started the beginning that the negative-pressure sealed drainage technology is used in department of general surgery.The patent CN 2276350 that Wang Yanfeng, Qiu Huade professor obtain authorizing on March 18th, 1998 in China is first patent of negative-pressure sealed drainage technology.From then on, the negative-pressure sealed drainage technology has obtained bigger development in China.
The negative-pressure sealed drainage technology realizes through negative-pressure sealed drainage system, and it comprises that porous foam cushion, an end are arranged on drainage tube in the porous foam cushion, are used for the sealing film of sealing porous airfoam cushion.The porous foam cushion of assembling drainage tube is laid on the wound surface, seals, and drainage tube is connected negative pressure, thereby set up the drain district of a sealing, carry out negative-pressure sealed drainage constantly at the wound surface place with sealing film.Compare with existing common changing dressings; The negative-pressure sealed drainage technology can will be removed through porous foam cushion and drainage tube by exudate in the drain district and slough at the right time; Thereby make by the drain district and can reach " nil product is gathered " state; Wound surface can be under the lasting cleaning ambient, greatly reduces the heavily absorption of body contratoxin; Even there is bigger lacuna to exist, lacuna also quickens to dwindle because of the existence of negative pressure.As far as shallow table wound surface, sealing film and porous foam cushion also make local environment more near physiological moisture state; Simultaneously, the negative pressure that acts on the wound surface soft tissue stimulates, and helps the improvement of local microenvironment and disappearing of tissue edema, has quickened the new life of granulation tissue in the wound surface, shortens wound healing time.Under negative-pressure sealed drainage technology treatment, need not to change dressings in wound surface 3-7 days, reduced medical worker's workload, reduced the patient suffering, reduced the general practice expense.
In China negative-pressure sealed drainage technology adaptable across fields such as traumatology department, orthopaedics, department of general surgery, Department of B urns.
