Description
Technical field
The present invention relates to the technical field of medical apparatus and instruments, particularly relate to a kind of negative pressure drainage dressing with attraction and pre-washing function.
Background technology
Wound surface enclosed negative pressure treatment technology is on the basis of clinical traditional negative pressure treatment method, wound surface puts medical sponge body, the biological hyaline membrane of wound surface is closed, with semipermeable membrane, medical sponge and wound surface are closed again, form an airtight drainage system, prevent extraneous bacterial invasion, improve wound surface microcirculation blood flow velocity, expansion blood capillary, promotes the granulation speed of growth, thus increases the effect of wound surface quickly-healing.Wound surface closed negative pressure treatment technology is the new Wound treatment technology that development in recent years is got up, and especially injures chronic wound surface in refractory to treatment patient to burning (wound), can drain slough, alleviates gradient of infection, and creation is conducive to the microenvironment of wound healing.
Existing negative pressure drainage dressing has two negative-pressure drainage tubes, two negative-pressure drainage tube one end are inserted in sponge dressing, after the other end merges into a house steward by tee T, be connected with Negative pressure machine, Negative pressure machine carries out continuing or intermittent negative inspiratory pressure to sponge dressing, the juice of wound surface and edematous fluid is sucked.But this negative pressure drainage dressing can only carry out negative inspiratory pressure, during the many and thickness of dawn wound secretion, be difficult to be sucked out or be adsorbed on spongy body block its microcellular structure, even by vacuum suction blockage, cause vacuum suction failure.The negative pressure suction device that existing market is all is in addition all without the effect intervened wound surface.
Summary of the invention
Technical problem to be solved by this invention is for the above-mentioned state of the art, and a kind of negative pressure drainage dressing is provided, can according to wound surface situation, pouring into wound surface and rinsing makes its secretions be diluted, secretions and edematous fluid are easily sucked out, be unlikely to be collected in below spongy body, cause traumatic infection, or blocking spongy body microcellular structure or negative-pressure suction pipe and cause vacuum suction failure.In addition, while the effective vacuum suction effect of guarantee, also as required, the medicine (passing through perfusion cannula) of some infection or wound healing can be applied to wound surface, create advantageously in the microenvironment of wound healing.
The present invention solves the problems of the technologies described above adopted technical scheme:
A kind of have the negative pressure drainage dressing attracted with pre-washing function, comprise spongy body and at least one drainage catheter, drainage catheter one end is inserted in spongy body, the other end is connected with negative pressure source, drainage catheter inserts on the duct wall in spongy body and has several vacuum suction through holes, wherein: negative pressure drainage dressing also includes perfusion pipeline, perfusion pipeline to insert in spongy body and can inject flushing liquor in spongy body or medicinal liquid is intervened wound surface, and the wound extract in spongy body, flushing liquor and medicinal liquid negative pressure can be absorbed by drainage catheter.
For optimizing technique scheme, the concrete measure taked also comprises:
Above-mentioned perfusion pipeline comprises supervisor and is in charge of, and is in charge of and is placed in spongy body, is in charge of end and is connected with supervisor, point tube wall has several orifices, the flushing liquor that perfusion pipeline is injected or the even spray of medicinal liquid energy to spongy body everywhere.
Above-mentioned is in charge of in spongy body in netted laying.
The above-mentioned connecting pipeline be in charge of for several laterally, vertically interlocks.
Above-mentioned orifice is arranged on the intersection of lateral duct and vertical pipeline.
Above-mentioned being in charge of is laid in vein shape in spongy body.
Above-mentioned being in charge of includes a rough segmentation pipe, and rough segmentation pipe is that divergent shape has separated several segmentation pipes to spongy body surrounding, and rough segmentation pipe and segmentation pipe are provided with orifice.
The quantity of above-mentioned drainage catheter is one.
Vacuum suction through hole on above-mentioned drainage catheter is interspersed.
A kind of negative pressure drainage dressing with attraction and pre-washing function of the present invention, there is drainage catheter and perfusion pipeline simultaneously, flushing liquor or medicinal liquid can be injected spongy body by perfusion pipeline, and intervene wound surface, the wound extract in spongy body, flushing liquor and medicinal liquid negative pressure are absorbed by drainage catheter.By injecting flushing liquor or medicinal liquid, spongy body can be made to keep moistening, and medicinal liquid can be intervened wound surface, and not yet finds that there is the technical scheme that drain dressing arranges the injection of perfusion pipeline in prior art.In spongy body, the increase of liquid can make the fluid flow in whole drain dressing increase, easier by wound surface produce dirt wash away, air intake passage not easily blocks, draw juice and edematous fluid efficiency better.In order to increase the beam efficiency of perfusion pipeline, the present invention also improves the shape of perfusion pipeline, perfusion pipeline changes the structures such as netted, vein shape, vascular system shape into, perfusion pipeline is allowed to extend to each corner of spongy body, carry out uniform beam, medicinal liquid can be made to be dispersed in whole spongy body, medicinal liquid intervention can not to be had by generating portion wound surface, the situation that part wound surface contacts without medicinal liquid.
