Description

Body surface organization's negative-pressure sealed drainage system
Technical field
This utility model relates to body surface organization's negative-pressure sealed drainage system.It is to aim at various body surface organizations ulceration district treatment and design a kind of is used for the device to reason wound, burn, infection, compressing, endocrine disturbance, vascular occlusion, radio exposure, operation, postoperative complication, worm Serpentis sting and bite, former resulting wound surface such as freezing wound carries out the negative-pressure sealed drainage treatment.
Background technology
Negative-pressure sealed drainage technology (vacuum sealing drainage/VSD is called for short the VSD technology) 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 VSD technology first in 1994, started the beginning that the VSD technology is used in department of general surgery, Wang Yanfeng, Qiu Huade professor in authorized patent CN 2276350 on March 18th, 1998, is first patent of VSD technology in China.From then on, the VSD technology has obtained bigger development in China.
Existing VSD technology basic configuration comprises negative pressure source (comprising the central negative pressure device that medical attractor or hospital use), drainage tube, breathable films (hereinafter to be referred as sealing film), joint (comprising two pass joints, three way cock or multiple-pass joint), the drainage container of polyvinyl alcohol foam or other medical porous foam, sponge or gauze (hereinafter to be referred as the porous foam cushion), Pasting sealing usefulness are formed.Its version is: the drainage tube of an end band side opening (is generally two pipes of parallel placement, the porous foam cushion of small dimension is a pipe, big slightly specification, three of general parallel placements pipe or more than) feed in the hole-drilled porous foam cushion, when using polylith porous foam cushion, by three way cock, two pass joints or multiple-pass joint the port of export of drainage tube is merged into an outlet again, connect the negative pressure source drain, with liquefied material drains such as the fragment of tissue of the oozing of blood in the tissue, sepage, liquefaction and necrosis and puss to drainage container.
In the practical application, the porous foam cushion is wrapped up many side openings drainage tube, be placed on the wound surface or the wound intracavity, the reuse sealing film tightly seals the porous foam cushion and the drainage tube port of export, make it to be hedged off from the outer world, connect negative pressure source, just formed an efficient drainage system (VSD system).In this system, negative pressure is delivered to the porous foam cushion through the rigidity of drainage tube, and can negative pressure be distributed in each point on the porous foam cushion along with the trend of drainage tube.Because the bubble of the hole in the porous foam cushion interconnects and high resilience, negative pressure can arrive the every bit in target drain district, forms an omnibearing drain.Block derivated bigger, that quality is not too hard can be cut apart with plasticity under suction function becomes graininess, and the hole of process porous foam cushion enters drainage tube, is sucked rapidly in the drainage container again; The bulk derivated that may stop up drainage tube is then stopped by the porous foam cushion, can only leave body with the porous foam cushion when removing or change drain attached to porous foam cushion surface.The sealing of sealing film is maintained the negative pressure as drain power, also makes by the drain district simultaneously to be hedged off from the outer world, and has prevented pollution and cross infection effectively.Because negative pressure is through being uniformly distributed in by the surface in drain district as mesomeric soft porous foam cushion, contingent internal organs or tissue is sucked out or pressurized and complication (" negative-pressure sealed drainage technology " the 2nd edition P3-P4, Qiu Huade Song Jiuhong chief editor publishes the People's Health Publisher) such as the ischemia that causes, necrosis, perforation in the time of can preventing single drainage tube negative pressure drainage effectively.
Compare with existing common dressing change, the VSD technology can will be removed at the right time by exudate in the drain district and slough, can be reached " nil product is poly-" state in the drain district, wound surface can obtain clean environment soon, reduces the heavily absorption of body contratoxin greatly; Even there is bigger lacuna to exist, lacuna also will quicken to dwindle because of the existence of negative pressure, and for shallow table wound surface, sealing film and porous foam cushion also make the more approaching physiological moisture state of local environment; 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; In 3-7 days of VSD treatment, all do not need to change dressings again, reduced medical personnel's workload, reduced the patient suffering, reduced the general practice expense.
The VSD technology is widely used in China: fields such as traumatology department, orthopaedics, department of general surgery, Department of B urn.
But existing VSD technology is in the use of surface wound drain, still there are the following problems: in clinical practice uses, be with lapping and healthy skin integral sealing together with sealing film, hair follicle in the healthy skin needs normal water-permeable and air permeable metabolism, just require the penetrating rate of sealing film to be the bigger the better, otherwise erythra can appear in healthy skin, folliculitis, phenomenons such as the moisture dipping turns white, cause the patient to have a mind to because of malaise symptoms such as itch or scratching by mistake, the friction sealing film, also can cause between skin and the sealing film because the moisture dipping, the sealing film viscosity diminishes, throw off from skin surface, make the air admission seal area finally cause negative-pressure sealed drainage to lose efficacy then.But the porous foam cushion needs sealing fully, require the penetrating rate of sealing film the smaller the better again, otherwise will cause that the porous foam cushion is owing to long small circulation of air causes loss of moist, the porous foam cushion is become dry, finally cause the porous foam cushion to follow the string and moist environment, delayed wound healing time; So this has just formed the contradiction that has two retroaction demand principles in an integral body, the sealing film that uses is the very big ventilated membrane of penetrating rate now, the use of this film can guarantee the homergy of healthy skin substantially, but the phenomenon that the porous foam cushion becomes dry, hardens takes place easily, thereby have a strong impact on drainage effect, prolong the healing time of wound surface.
Therefore, existing VSD technology is improved in the use in the surface wound tissue healing become a very urgent important process.
