Description
Technical field
The present invention relates to medical instruments field, specifically a kind of test macro for Medical negative pressure closed drainage conductivity of materials.
Background technology
Negative-pressure sealed drainage technology (vacuumsealingdrainage is called for short VSD) is that German ULM university doctor WimFleischman initiated in 1992, and forms theoretical blank, for the drainage of limb wounds; Within 1994, negative-pressure sealed drainage technology is applied to department of general surgery by Chinese professor Qiu Huade first, start the beginning that negative-pressure sealed drainage technology is applied in department of general surgery, Wang Yanfeng, Qiu Huade professor in authorized patent CN2276350 on March 18th, 1998, is first patent of negative-pressure sealed drainage technology in China.From then on, negative-pressure sealed drainage technology obtains larger development in China.
Negative-pressure sealed drainage technology is realized by negative-pressure sealed drainage system, and it comprises porous foam cushion, one end is arranged on the drainage tube in porous foam cushion, the sealing film for sealing porous airfoam cushion.The porous foam cushion of assembling drainage tube is laid on the surface of a wound, with sealing film sealing, and drainage tube is connected negative pressure, thus establish a closed drainage district at surface of a wound place, carry out negative-pressure sealed drainage constantly.
With existing common change dressings compared with, negative-pressure sealed drainage technology can be removed by porous foam cushion and drainage tube at the right time by by the exudate in drainage district and slough, thus make can be reached " nil product is gathered " state by drainage district, under the surface of a wound can be in lasting cleaning ambient, greatly reduce the heavily absorption of body contratoxin; Even if there is larger lacuna to exist, lacuna also accelerates because of the existence of negative pressure to reduce.For the shallow table surface of a wound, sealing film and porous foam cushion also make local environment closer to physiological moisture state; Meanwhile, the negative pressure acted on surface of a wound soft tissue stimulates, and is conducive to the improvement of local microenvironment and disappearing of tissue edema, accelerates the new life of granulation tissue in the surface of a wound, shorten wound healing time.Under the treatment of negative-pressure sealed drainage technology, without the need to changing dressings in surface of a wound 3-7 days, reducing the workload of medical worker, decreasing patient suffering, reducing general practice expense.
In China, negative-pressure sealed drainage technology is widely used in: the fields such as Department of traumatology, orthopaedics, department of general surgery, Department of B urn.
The action principle of negative-pressure sealed drainage and function, largely depend on the drainage effect of negative pressure to wound surface.For the negative pressure drainage negative pressure settings of the best, a lot of Clinical Papers is had to describe both at home and abroad, but without exception, all be its theoretical foundation with the negative pressure value of wound surface, this has become the treatment common recognition in negative-pressure sealed drainage field: Wound-surface negative pressure is lasting, stable, balanced, contributes to the healing of the surface of a wound.
Domestic current negative-pressure sealed drainage system, general by two kinds of use-patterns: the use-pattern (see accompanying drawing 1) of intermediate cannula and sucker drainage way (see accompanying drawing 2), the intubate of suction function in porous foam cushion material, or the sucker in porous foam cushion material, then negative pressure is conducted by porous foam cushion material, finally acts on the wound surface of a wound.Now, the effect of conduction to negative pressure treatment of porous foam cushion material itself serves very important effect.
Because negative-pressure sealed drainage technology time that emerges is still short, special equipment is not measured porous foam cushion material conduction in the market, on domestic and international market, the porous foam cushion material product of negative-pressure sealed drainage is very different, generally lack the conductive technical controlling of porous foam cushion material, had a strong impact on the treatment level of patient.
