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 (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, start 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, and it comprises that porous foam cushion, one end are arranged on drainage tube in porous foam cushion, 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 to negative pressure, thereby set up the drainage district of a sealing at surface of a wound place, carry out negative-pressure sealed drainage constantly.
Compared with existing common changing dressings, negative-pressure sealed drainage technology can will be removed by porous foam cushion and drainage tube at the right time by the exudate in drainage district and slough, thereby make can be reached by drainage district " nil product is poly-" state, the surface of a wound can be under lasting cleaning ambient, greatly reduces 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, reduce medical worker's workload in surface of a wound 3-7 days, reduce patient suffering, reduce 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 negative pressure value taking wound surface is as 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 (seeing accompanying drawing 1) of intermediate cannula 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 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 control of porous foam cushion material, had a strong impact on patient's treatment level.
