Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of negative pressure treatment systems and the dressing component thereof that are used for the treatment of open gash.
Background technology
At present, in trauma care process, prevention infection, promote wound site blood circulation thus healing acceleration is the main target that medical personnel will reach always.But the wound of the wound that the excessive wound of some wound surface, chronic disease cause or severe infections, is difficult to be able to rapid healing by the treatment of traditional debridement treatment.Such wound, local blood circulation is blocked, and does not have enough blood to flow to wound site, causes organizing deficiency of oxigen and nutrient substance around wound surface, does not have the traumatic infection that enough immunocompetence opposing microorganisms cause.Easily cause septicemia, compromised immune wound or the prolonged difficulty of wound more.These phenomenons have become clinical in wound surface nursing, do one's utmost to avoid.
The negative pressure attraction treatment system of wound uses recent two decades, the tissue exudates produced for attracting wound surface.Thus eliminate the retardance of wound surface local, ensure local blood circulation, guarantee the blood oxygen amount of wound site and the conveying of nutrient substance.Thus accelerating wound healing, improve anti-infective immunity.
Clinical research shows, when negative pressure is in 75mmHg to 335mmHg scope, most of wound surface can obtain suitable treatment.Transudate can be made comprehensively to be removed, wound tissue and surrounding tissue can be kept again to preserve from.
But existing negative pressure wound treating system, general use a pipeline to lead to wound, both negative pressure at suction wound place, simultaneously the transudate at suction wound place again.The weak point of such design is: one be evacuation and the pipeline measuring wound negative pressure value is same, when there is the transudate aspirated in pipeline, or pipeline is blocked by full-bodied transudate, there is comparatively big error in the negative pressure value then in pipeline and the negative pressure value of wound, is difficult to the true negative pressure value being accurately measured wound; Two is can only the setting negative pressure value of machinery or the malleation-negative pressure value of mechanical periodicity and retention time, and cannot carry out the change of pressure according to the true environment of wound, therefore in vacuum suction process, patient easily produces sense of discomfort; Three is that the wound fluid be absorbed in pipeline easily returns wound surface when negative pressure wound treating system is in pressure cycle alternation procedure, produces and repeats wound surface pollution.Also some technology are had to have employed two pipelines, one of them pipeline is gas suction, another pipeline is wound fluid suction, but because the port of two pipelines in wound lacks effective isolation, two pipelines can interact in negative pressure-pumping process, are difficult to guarantee that gas piping and liquid line can work alone completely.
Summary of the invention
Technical problem to be solved by this invention is: pressure detecting pipe wound end port and liquid suction pipe wound end port lack effectively isolates, and the obstruction that wound fluid can be inhaled into build-up of pressure detector tube from pressure detecting pipe causes wound force value to measure distortion.
The invention provides a kind of negative pressure wound therapy dressing component, it is characterized in that, comprising:
Transfer layer of liquid, covers wound surface for transmitting wound fluid;
Lid, to cover in described transfer layer of liquid and under negative pressure state, to there is at least one cavity with described transfer layer of liquid;
Liquid suction pipe, port is arranged in described transfer layer of liquid for suction wound transudate;
Pressure detecting pipe, port is arranged at least one cavity described for detecting wound force value.
Further, described lid is hard material.
Further, described hard material is polrvinyl chloride.
Further, described hard material is ABS plastic, polystyrene or polyformaldehyde.
Further, be provided with the barrier layer for stopping wound fluid of breathability in the cavity between described transfer layer of liquid and described lid, described pressure detecting pipe port is arranged in the cavity between described barrier layer and described lid.
Further, described barrier layer is network structure.
Further, described barrier layer is attached on described lid.
Further, described transfer layer of liquid is netted open-cell polyurethane or polyether foam.
Further, described pressure detecting pipe is provided with perforate on the tube wall of wound end.
Correspondingly, the present invention also provides a kind of negative pressure wound treating system, it is characterized in that, comprises negative pressure treatment equipment and the described dressing component with this negative pressure treatment equipment connection.
The embodiment of the present invention arranges pressure charge monitoring and the liquid suction respectively of two independent pipelines by negative pressure wound therapy dressing component, pressure monitoring line ports is positioned on transfer layer of liquid, rigid cover and near the inner surface of rigid cover, liquid suction pipe road port is arranged in the porous body of transfer layer of liquid.Use disconnected two pipelines each other can avoid interference and impact mutually between pressure monitoring and liquid suction, the data of pressure monitoring can also be made simultaneously more accurate.Avoid in the pipeline because of suction wound transudate and there is transudate fluid column or blocked by full-bodied transudate, cause wound pressure values to measure distortion.
