Description
Technical field
The present invention relates to a kind of negative pressure closed drainage device.It is a kind of negative-pressure sealed drainage that is applicable to body surface organization or body cavity pathological changes and carries out.
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 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 central negative pressure device that medical attractor, hospital use or negative pressure drainage vessel etc.), drainage tube, compositions such as the breathable films (hereinafter to be referred as sealing film) of polyvinyl alcohol foam or other medical porous foam, sponge or gauze (hereinafter to be referred as the porous foam cushion), Pasting sealing usefulness, joint (comprising two pass joints, three way cock or multiple-pass joint), drainage container.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 pipes or more of general parallel placement) 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 drainage container, connect negative pressure source (existing also have the negative pressure drainage vessel that drainage container and negative pressure source are made of one) again, 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 plastotype under suction function becomes graininess, enters drainage tube through the hole of porous foam cushion or the hole bubble that connects mutually, 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 human 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, make to be reached " nil product is poly-" state in the drain district, wound surface can obtain clean environment soon, 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, 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.
Existing VSD technology is constantly improved it by inventor Mr. Song Jiuhong, the VSD technology is at surface wound drainage technology comparative maturity, but also still there is a lot of problems in the application in vivo of this technology: 1., sealing is inconvenient, during the sealing film sealing neither one preferably carrier as support.Good sealing is the key that guarantees drainage effect, it also is where the shoe pinches in the operation of whole negative-pressure sealed drainage, encapsulating method commonly used comprises: (" negative-pressure sealed drainage technology " the 2nd edition P20-P24 such as puncture method, " mesentery " method, sewing and " making dumplings " method, Qiu Huade Song Jiuhong chief editor, the People's Health Publisher publishes).But above-mentioned encapsulating method is all very loaded down with trivial details in the operation of reality, and operation and exercise that operative doctor all needs to carry out repeatedly could be grasped, and patient's misery is bigger.And sealing insecurely, the most important reason of leaking gas often causes the weakening even the failure of the VSD systematic treating effect that causes because of gas leakage easily.2., often need the on-the-spot splicing of doctor, there not be the industrial products of finalizing the design for endoceliac negative-pressure sealing drain.That is to say use when being applicable to the drawing assembling device and in body cavity, do the negative-pressure sealing drain of surface wound extremely inconvenient.
Therefore, existing VSD technology is improved, and made it be applicable to wound tissue healing in body surface organization or the body simultaneously, and make things convenient for pad pasting to become a very urgent important process.
