Description
Technical field
The present invention relates to a kind of Wound care device, relate in particular to a kind of can carrying out in order to negative pressure wound treatment in the peripheral sealed environment that forms of wound, can avoid simultaneously conduit to be positioned at that the wound top produces structural obstructions or the extruding wound causes the sense of discomfort of sufferer, and the Wound care device that is applicable to negative pressure treatment that takes place of the situation that can avoid conduit and block because of bending.
Background technology
Vacuum therapeutic wound healing (Vacuum Assisted Closure; V.A.C.Therapy); or negative pressure wound treatment (Negative Pressure Wound Therapy; abbreviate NPWT as); a kind of for complementary physiotherapy; its principle is to utilize negative pressure pump in conjunction with sealing patch and porous material as the tool bio-compatibility of dressing; in wound, form subnormal ambient; add negative pressure and make the porous material volume-diminished; cause wound to middle deflation indirectly; by material molecule shear stress traction border cell; promote the cell division hypertrophy, accelerating wound healing, negative pressure is transmitted in wound through porous material; remove and attract the iuntercellular tissue fluid to flow; promote indirectly outside blood vessel hyperplasia and the local blood circulation, still antibacterial pus and blood in the wound and too much tissue fluid can be extracted out, can avoid edema; reduce the inflammation chance, moist healing environment is provided; protection wound and then minimizing wound healing need the time.
The basic framework of vacuum therapeutic wound healing is put into dressing in wound after, with sealed Cellophane sealing wound, connects the conduit of a connection negative pressure source again, by negative pressure source the transudate in the wound is drawn in the waste liquid holding vessel; Conduit in this existing framework is directly to insert wound, therefore above wound, form a stereochemical structure, make wound be difficult for outside the sealing, when wound is positioned at patient's sole (for example diabetic foot) or back (for example decubital ulcer), this kind existing structure not only causes extremely discomfort to patient's wound, and easily cause the destroyed sealing of sealed Cellophane, or conduit bent obstruction, thereby cause and effectively to treat because of extruding.
At patent, No. the 6626891st, U.S.'s patent of invention " Drainage system to beused with an open wound; an element which is used thereby for placing a drainagetube or hose; and a method of using said drainage system " for example, it is that one side in a tabular assembly is provided with the protruding part, the inner space that forms, this protruding part, this spatial end runs through this protruding part and forms an opening, this opening can connect negative pressure source for external catheter, and this tabular assembly is provided with a plurality of holes and is communicated with this protruding part volume inside, the inner space that forms, this protruding part is covered in the dressing of wound, cover this tabular assembly and stick on the patient skin on every side with glued membrane again, can be by this conduit with the transudate of wound by dressing, the hole of this tabular assembly, the inner space of this protruding part is drawn out of via this conduit at last; Only this tabular assembly has certain degree of hardness and thickness, and this protruding part and conduit are positioned at the wound central part, all can make the patient produce sense of discomfort, this conduit is then pullled accidentally because of external force easily and is got loose, or cause blocking because of bending, in addition, its glued membrane also easily because long-time compressing and with tabular components apart, influence air-tightness.
No. the 7273054th, United States Patent (USP) " Surgical drape and head for wound treatment " and for example, it is that one side in a flat body is provided with a plurality of column structures, be provided with a joint in the another side of this flat body and run through this flat body, this joint can connect negative pressure source for external catheter, this one side that is provided with column structure is covered in the dressing of wound, cover this flat body and stick on the patient skin on every side with glued membrane again, can be by this conduit with the transudate of wound by dressing, space between column structure, joint is drawn out of via this conduit at last; In the same manner, similar with the existing shortcoming of last existing case (No. the 6626891st, U.S.'s patent of invention), the set column structure of its flat body and bottom has certain degree of hardness and thickness, and this joint and conduit are positioned at the wound central part, all can make the patient produce sense of discomfort, and this conduit is then pullled accidentally because of external force easily and got loose, or cause blocking because of bending, in addition, its glued membrane also separates with flat body because of long-time compressing easily, influences air-tightness.
No. the 7128735th, United States Patent (USP) " Reduced pressure wound treatment appliance " for another example, it utilizes a funnelform cover body to cover wound, be provided with a conduit by this cover body inside and extend to this cover body outside and connect negative pressure source, can wound fluid be extracted out by this conduit; Though this case can improve air-tightness, yet bulky cover body causes very big inconvenience and sense of discomfort to patient action, and conduit is bent easily and causes blocking.
Before the comprehensive above-mentioned patent case structure as can be known, existing patent does not solve air-tightness, discomfort and obstructing problem fully.
Summary of the invention
Because the disappearance of prior art, the present invention proposes a kind of Wound care device, can carry out in order to negative pressure wound treatment in the peripheral sealed environment that forms of wound, while can avoid conduit to be positioned at wound top generation structural obstructions or the extruding wound causes the sense of discomfort of sufferer, and the situation generation that can avoid conduit to block because of bending.
For achieving the above object, the present invention proposes a kind of Wound care device, and it comprises one first body, one second body and at least one assembly with hole, and this first body has the thin film of stickiness, and this first body is provided with at least one first hole; This second body is made by the material with pliability and water proofing property, this second body is provided with at least one second hole and at least one the 3rd hole, this second hole and the 3rd hole are interconnected and form an accommodation space in this second body interior, this second body is connected in this first body, and this second hole correspondence is arranged at the position of this first hole; This assembly with hole is arranged in the accommodation space of this second body.
