Description
Technical field
The present invention relates to Medical wounded surface dressing field, cleaning device, Medical wounded surface in specifically a kind of Medical wounded surface dressing
Dressing and purging system.
Background technology
Negative-pressure sealed drainage technology (vacuum sealing drainage, abbreviation VSD) is German ULM universities Wim
Doctor Fleischman is pioneering in 1992, and forms theoretical blank, the drainage for limb wounds；China Qiu Huade in 1994
Negative-pressure sealed drainage technology is applied to department of general surgery by professor first, has started the elder generation that negative-pressure sealed drainage technology is applied in department of general surgery
River.
Existing VSD technologies basic configuration includes negative pressure source (including the central negative pressure that medical negative pressure suction machine, hospital are used
Device or negative pressure drainage vessel etc.), drainage tube, hydrophilic foam or other medical hydrophobic foams or sponge kind dressing
Or gauze dressing (being referred to as perforated foams to above-mentioned medical material below), Pasting sealing film, drainage container are constituted.
Negative pressure source drainage is connected, can be by liquefied substances such as the oozing of blood in tissue, sepage, the fragment of tissue of liquefaction and necrosis and festers
Matter is drained in drainage container.Slough and toxin, fester etc. can be expelled directly out in vitro by above-mentioned technology, it is to avoid toxin weight
Absorb, the rapid cleaning surface of a wound；Meanwhile, high negative pressure attraction can effectively facilitate granulation and mushroom out, and shorten wound healing time.Make
Use the technology, patient can be to be not required to dressing in 5-7 days, it is to avoid cross-infection, reduces medical personnel's workload, reduces trouble
Person's pain, reduces fatal rate, the disability rate of wound.
VSD technologies are mainly by this medical high polymer dressing of porous foam cushion to realize.This dressing is both
Negative pressure transmitting medium, while being also that the materials such as slough, fester, sepage, other toxic products and toxin are introduced into drainage tube
Drainage medium.The foam dressing for negative-pressure sealed drainage is broadly divided into two kinds in the market：Hydrophobicity dressing and hydrophilic
Property dressing.Hydrophobicity dressing is generally that PU foaming materials are formed, and foam pores are larger, and Penetration ration is higher；Due to its hydrophobic characteristic,
Typically will not be aqueous in foam, therefore negative pressure conductive performance is splendid.Hydrophilic dressing is generally that PVA foaming materials are formed, foam hole
Gap is smaller than hydrophobicity dressing, and material Penetration ration is relatively low, but the need for also meeting negative pressure drainage treatment；Due to its hydrophilic spy
Property, dressing surface can form one layer of water molecule film, and separated dressing directly contacts with the endothelial cell with granulation tissue, can
Granulation tissue is prevented to grow into dressing, it is to avoid drawing bleeding, material safety is high.
But above-mentioned dressing equal existing defects in clinical practice.Hydrophobicity dressing (PU) is due to its hydrophobic characteristic, material
Material surface does not have protective layer, and granulation tissue can be grown into foam pores, easily occurs drawing bleeding；Also due to hydrophobicity dressing
(PU) stretching resistance is poor, easily produce chip come off, then cause the surface of a wound create chamber foreign matter inflammatory reaction (rejection) and
Secondary infection, therefore there is larger problem in material safety.U.S. FDA report display, using PU dressing, patient exists dead
With the situation for aggravating wound.It is short (U.S. FDA is reported and pertinent literature was shown no more than three days) using the PU dressing dressing cycles,
Cost is high, and the labor intensity of medical personnel is big, and patient is also more painful.Hydrophilic dressing (PVA) is due to its water-wet behavior, material sheet
Body is moistening, although its Penetration ration is relatively low, can also meet the treatment requirement of negative pressure drainage, but is due to that material is aqueous, because
This its negative pressure conductive performance is poor, and negative pressure is easily produced when the large area surface of a wound is used and conducts weak area, secondly PVA material dehydrations
Easily gradually slowly it is dried afterwards, causes Penetration ration further to decline, weakens therapeutic effect.
In the past more than ten years, people expand the spy about Wound healing mechanism and material in macromolecule level
Beg for.Recent study result shows：Hydrophilic dressing (PVA) contributes to the recovery of wound, is used with composite medicine, can more accelerate wound
The cleaning of mouth and the surface of a wound recover.But, because product has negative pressure requirements, localized contact face to need to ensure sterile and uses week
Phase is generally defined in 5 to 7 days, causes product to be currently on the market respectively provided with following defect：
1) it is generally that easy detergent line is connected with negative pressure line inside the dressing of in the market, detergent line is used to clean
Dressing, negative pressure line is used to reclaim the liquefaction product such as oozing of blood, sepage, the fragment of tissue of liquefaction and necrosis and fester in tissue
Water substance, detergent line and negative pressure line, which are connected, can so cause the backflow of cleaning fluid original position directly to be siphoned away by negative tube, cause to apply
Expect that cleaning efficiency is low.
2) medical dressing majority needs to be cut according to the size of wounds, is needed the drainage in dressing after cutting
Pipe is extracted into suitable position, easily causes products air tightness to be deteriorated during pipe is taken out, the problems such as leaking air, so as to influence to bear
Press drainage effect.
3) dressing at present on the market should not unpick and wash recycling, cause usage cycles short, under utilization rate；
4) existing product can not accomplish the direct administration of the surface of a wound.
The content of the invention
It is an object of the invention to provide in the Medical wounded surface dressing that cleaning fluid efficient circulation is realized inside Wound dressing
Cleaning device.
To achieve the above object, the present invention provides following technical scheme：
