Description
Technical field
The utility model 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 (vacuum sealing drainage is called for short VSD) is that German ULM Wim doctor Fleischman of university is pioneering in 1992, and forms theoretical blank, for the drainage of limb wounds; Within 1994, Chinese professor Qiu Huade is applied to department of general surgery by negative-pressure sealed drainage technology first, started the beginning of negative-pressure sealed drainage technology in department of general surgery's application, Wang Yanfeng, Qiu Huade professor in authorized patent CN 2276350 on March 18th, 1998, is first patent of negative-pressure sealed drainage technology in China.From then on, negative-pressure sealed drainage technology has obtained larger development in China.
Negative-pressure sealed drainage technology realizes by negative-pressure sealed drainage system, it comprise porous foam cushion, one end be arranged on drainage tube in porous foam cushion, for the sealing film of 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 to negative pressure, thereby at surface of a wound place, set up the drainage district of a sealing, carry out negative-pressure sealed drainage constantly.
Compare with existing common changing dressings, exudate and slough in negative-pressure sealed drainage technology Neng Jiangbei drainage district are removed at the right time by porous foam cushion and drainage tube, thereby Shi Bei drainage district can reach " nil product is poly-" state, the surface of a wound can, under lasting cleaning ambient, greatly reduce the heavily absorption of body contratoxin; Even if there is larger lacuna to exist, lacuna is also because the existence of negative pressure is accelerated to dwindle.For the shallow table surface of a wound, sealing film and porous foam cushion also make local environment more approach physiological moisture state; Meanwhile, the negative pressure acting on surface of a wound soft tissue stimulates, and is conducive to the improvement of local microenvironment and disappearing of tissue edema, has accelerated the new life of granulation tissue in the surface of a wound, shortens wound healing time.Under negative-pressure sealed drainage technology treatment, without changing dressings, reduced medical worker's workload in surface of a wound 3-7 days, reduced patient suffering, reduced 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 best negative pressure drainage negative pressure settings, there is a lot of Clinical Papers to describe both at home and abroad, but without exception, all that to take the negative pressure value of wound surface be its theoretical foundation, 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, generally by two kinds of use-patterns: the use-pattern of intermediate cannula (seeing accompanying drawing 1) and sucker drainage way (seeing 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 conduction of porous foam cushion material itself has played very important effect to the effect of negative pressure treatment.
Because negative-pressure sealed drainage technology time that emerges is still short, not having in the market special-purpose equipment measures porous foam cushion material conduction, on domestic and international market, the porous foam cushion material product of negative-pressure sealed drainage is very different, generally lack the conductive technology of porous foam cushion material is controlled, had a strong impact on patient's treatment level.
