The structure overcomes the problem of possibility of easy occurrence of 'retrograde infection' when flushing with a conventional drainage tube, and in the structure, the flushing pipe is arranged inside the drainage tube, and the side holes are disposed on the flushing pipe, thereby avoiding wound surface 'retrograde infection' caused by drained materials reentering a wound surface along with flushing liquor.
Description
Technical field
This utility model relates to parts on the negative pressure closed drainage device, and more particularly it is a kind of airfoam cushion structure of drainage tube of built-in band syringe pipe.This utility model is applicable to Wound-surface negative pressure closed drain of body surface organization and endoceliac negative-pressure sealed drainage.
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 central negative pressure device that medical attractor, hospital use, negative pressure bottle etc.), drainage tube, 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 etc.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 hole in the porous foam cushion is steeped or hole 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, 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 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 are held 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.
1., by the too much or a large amount of sticky derivated of the slough in the drain district but existing VSD technology is as easy as rolling off a log generation drain blocking problem in the drain process: causing drain to stop up may be owing to following reason:, exceed the disposal ability of drainage tube.Be positioned over by attached full slough in the surface of the porous foam cushion in the drain zone or sticky derivated, at this moment, can not be passed through the porous foam cushion by the drain in the drain district.2., since sealing film poorly sealed (sealing of smooth broad position is than being easier to, and at complex-shaped positions such as face, perineal position, brothers, then seals difficult.When wound surface is big simultaneously, more because of drainage tube, also be not easy sealing), because of the poorly sealed forfeiture that causes subnormal ambient, at this moment liquid and the granule in the drainage tube can not be attracted and the suction drainage container, forms one section dry derivated obstruction drainage tube and solidify in drainage tube.3., since sealing film poorly sealed, make porous foam cushion dealcoholysis hardening, cause the porous foam cushion to lose drainage.In addition, because of wound surface cleaning incomplete (as hemostasis fully), negative pressure uses grade lack of standardization also can cause drain to stop up in the drain process.
According to the situation that different reason generation drains are stopped up, can take different ways.As: if during, can in time change the porous foam cushion by attached full slough in the porous foam cushion in drain zone surface or sticky derivated.As if owing to sealing film poorly sealed (producing gas leakage), make to solidify in the drainage tube to form one section dry derivated obstruction drainage tube; Or make porous foam cushion dehydration hardening.Then can take to seal up sealing film, and in drainage tube, drive in the wrong direction simultaneously and inject normal saline modes such as (being commonly called as " washing pipe "), make drainage tube conducting again, or make the porous foam cushion recover elasticity again.But this mode can make drain reflux causes the possibility of wound surface " retrograde infection ".And, when having only a drainage tube, because of can not forming the loop of washing pipe and drain, and can't use if wound surface is less.
Chang Yong purging method now is: 1, put a root rubber pipe in addition on wound surface, but also need the extraction location with " mesentery method " caulking gum pipe, increased the probability of " gas leakage " and the difficulty of sealing; 2, from the retrograde flushing liquor that injects of former drainage tube, the sepage that drains may be refilled on the wound surface, cause " retrograde infection "; 3, puncture injects flushing liquor from the porous foam cushion, but need paste sealing film again at the broken hole position on the porous foam cushion, has increased the difficulty of operation.
Therefore, solve existing VSD technology when the drain obstruction takes place, washing pipe become an extremely important and urgent job smoothly.
