Description
Technical field
This utility model relates to a kind of medical auxiliary facilities technical field, particularly relates to a kind of Wound protection fixture.
Background technology
People can cause wound because of many factors come to harm body in life; Like outer wound wound, surgical wound and conduit infusion wound etc.; Just run into behind the wound and must protect and nurse wound; The severe complication of avoiding wound infection to cause; So good Wound protection nursing technique and product are most important to accelerating wound healing, mainly be wound to be protected nursing at present on the clinical medicine through the use wound dressing, these products mainly comprise spun-laced nonwoven fabric, transparent membrane dressing, foam dressing, foam dressing, bearing hydrocolloid dressing and functional dressing etc.; Adopt dissimilar dressing to protect nursing just can reach better effect to dissimilar wounds, if protection care method, technology and the inappropriate infringement that can increase the weight of wound on the contrary of product.So should pay attention to that wound that existing Wound protection nursing technique and product cause damages again or can not reach the optimal care effect because of the functional defect of product in the nursing process to wound.We protect the advantage of nursing and defective to analyze comparison according to by the characteristics of nuring wound wound being carried out simple classification and prior art and product to it, so that create the new product of better curative effect.
First kind wound is the wound of band infusion catheter; This type wound the nursing on except that fixedly securing the conduit; But also the wound that needs protection especially do not infected, and like the band central venous catheter, through the wound of peripheral vein central venous catheter, vein indwelling needle catheter, and some conduit needs the long-term indwelling of some months time to be used for treating disease; Preferable methods is to adopt transparent membrane dressing (PU film) directly capping conduit infusion wound and A/C clinically at present, and advantage is:
1, ultra-thin transparent, be convenient to observe at any time the wound changing condition;
2, compliance and fabulous with the sticking nature of skin and is difficult to after the skin adhesive to separate.
Therefore it more firmly is difficult for breaking away from than its dressings A/C and protection infusion wound, and waterproof.But it has following shortcoming:
1, because its compliance is good; The mobile gauffer that can not stop skin so can himself also produce same mobile gauffer along with the mobile gauffer of surface skin, therefore its conduit can produce displacement and damage conduit infusion wound when receiving external force tractive or body activity to cause that gauffer is moved in the skin surface generation;
2, the binding agent sealing label can cause that wound and surrounding skin are irritated on the infusion wound, produces inflammatory reaction such as contact dermatitis;
3, the liquid of not having a good sweat, perspiration gathers under wound and thin film, and the mouthfeel that is prone to cause injury is dyed, severe complications such as secondary phlebitis or blood infection;
4, in 3 to 6 days, need to change, if the longer time not more change dressings disinfect wound again and can cause infection.
Second type of wound is general wound such as surgical wound, trauma wounds etc.; Handle spun-laced nonwoven fabric and foam dressing that this type wound generally adopts band protective pad or liner, foam dressing, bearing hydrocolloid dressing dressing etc. clinically and carry out care protection, the advantage of this type dressing is:
1, has strong absorbability, can absorb the wound sepage, the zone diffusion of protecting from infection;
2, the direct wound contacting of binder free;
3, bearing hydrocolloid dressing can keep the moisture state of wound tissue, accelerates healing.
But the shortcoming that has is:
1, opaque (hydrocolloid is translucent) therefore can not be observed the wound situation of change at any time;
2, relatively its compliance of transparent membrane dressing, sticking nature are relatively poor; Rigidity hardness is stronger; Under the tension force effect, separate with skin surface easily and come off, so stationarity is also relatively poor, when the separation that is prone to come off in the wound that is easy to generate the body joint motion position of moving gauffer or when motion is perspired is obeyed in subsides;
3, water proofing property difference or non-watertight is met water the dressing tack coat is come off easy the separation with skin;
4, when wound surface skin is moved gauffer, can produces the relative displacement friction and damage wound tissue again, particularly be positioned at the wound at body joint motion position with protective pad or dressing that liner and wound directly contacted.
In addition; Above-mentioned these dressing all are directly tight, the repressive wound surface that covers; Therefore can bond with the secretions of wound tissue; When change dressings more, can cause wound tissue to damage again, though the part of wound contacting is that adhesion is relative through the adhesion technical finesse in these dressing.When wound was irregularly disinfected again, above-mentioned applying all must integral replacing simultaneously.
Except that above-mentioned technology, at present, the dressing of some preventing tissue adhesions or the Wound care device of " noncontact " are arranged also; Occur like wound cares such as " cover ", " framework " technology, but these preventing tissue adhering materials can not prevent the repulsion inflammatory reaction that adhesion and tissue produce foreign body fully, and these " covers " or " framework " Wound care device complex structure; Lack effective fixing means, be difficult to stable, mobile easily so that cause wound to destroy again; Can not be applied to central venous catheter, through the nursing of the fixing and conduit infusion wound of peripheral vein central venous catheter, vein indwelling needle catheter, and also comparatively complicated on making and using.So be difficult to clinically apply.
More than these to the existing protection nursing technique of wound and method except described defective; Can not prevent that all wound from tearing and split running into the wound that causes under external force or the tension force effect; Tackling wound at present clinically tears and splits and still do not have a kind of effective method and technology; Especially be positioned at the surgical wound and the trauma wounds at abdominal part, joint motion position; Because cough, postoperative abdominal distention, firmly defecation, joint are moved etc. and to be caused and tear and split, have a strong impact on wound healing and cause complication such as infection.
Whether for Wound protection care product and skin surface bonding firmly also is the key factor of decision wound care effect quality; Therefore the physiological property of human body surface skin will determine and influence the effect of method of wound care, product, and skin has following physiological property:
The first, skin is the organ of a secretion perspiration, and secreted perspiration will make protection secure attachment layer viscosity reduce, even come off.
The second, skin is one and comparatively soft can receive the external force effect and produce and move and the surface of gauffer with texture; Especially the joint part of motor function is being arranged; And the age is bigger, the more also easy more generation gauffer of skinfold, therefore, and when a more difficult gauffer or rigid protective secure attachment layer that can not gauffer adhere to skin surface; When adhesion surface receives the external force effect and produces the tension force that moves gauffer and do the time spent; At first it will resist displacement, the gauffer that the tension force that moves gauffer limits skin surface, when adhesion strength is not enough to resist this tension force, bonding plane is peeled off come off; Therefore rigidly fix adhesion layer when boning the article of fixing skin surface when use only, its advantage is that it can resist the mobile gauffer that tension force that skin moves gauffer limits the skin surface that bonding plane or its opening surround.Need be but its shortcoming is to resist the tension force that skin moves gauffer with the adhesion strength of skin; When this adhesion strength is not enough to resist skin and moves the tension force of gauffer or because of the adhesion surface tension force with skin, raising, rigid protective secure attachment layer will divide luxuriant coming off.But when a compliance protection secure attachment layer adheres to skin surface; Because its softness, ultra-thin, compliance good; Thereby the texture that can follow skin moves gauffer and produces same displacement gauffer; No matter under any displacement rugosity, can both keep pasting the clothes state with the good adhesion of skin surface, thus skin move gauffer tension force not with the adhesion strength opposing, therefore when the use compliance protects the secure attachment layer to protect medical products or the wound of fixing skin surface; Its advantage is its adhesion close and firm, even also difficult drop-off is being arranged under the situation of perspiration.But its defective is a protection secure attachment layer protects fixed medical supplies or wound to produce displacement and mobile gauffer along with the mobile gauffer of skin surface; Fix or have the fixing of wound dressing that inlet place conduit will be moved and the displacement of wound surface gauffer for the conduit that the conduit inlet is arranged, cause its wound again damage and wound with dressing relative displacement friction and injure wound tissue.
Three, the skin wound of allergic constitution can produce irritated and cause inflammatory reaction and infection adhesion layer, therefore is necessary to avoid the adhesion coating conduit of directly adhering to inject wound, surgical wound and trauma wounds.
Therefore to the advantage of said method and product application in the wound care protection and defective and according to the physiological property of skin; Be necessary to develop a kind of new method or product; Can inherit and integrate the advantage of prior art, overcome its defective, create the bonding protection fixing means and the new product that are fit to the skin physiology characteristic; Make technical method or product after the improvement, satisfy following requirement:
1, can effectively prevent tearing and splitting of wound (comprising operation stitching wound, trauma wounds, conduit infusion wound and some high-tension wounds).
2, can have permeability ground wound contacting secretions, rather than tight repressive contact, make product can effectively absorb the juice of wound slough, prevent local diffusion, but can or seldom not produce adhesion with wound tissue.
3, can make wound open, visual, be convenient to observe at any time the wound situation of change.
4, can be as using separately transparent membrane dressing can fixedly secure on the skin that is bonded in wound circumference and fixing infusion catheter, again can bonded dose do not paste on wound or the conduit infusion wound, the while is transparent again visual.
Displacement and the wound that causes that 5, can limit mobile gauffer and the infusion catheter of wound surface skin damage again, particularly the wound at body joint motion position or the more position of skinfold and conduit infusion wound.
6, according to the needs of wound characteristic, can prevent fully that wound surface from contacting (comprising dressing itself) with any foreign body, avoid wound to produce foreign body and repel inflammatory reaction.
7, can under the situation of integral replacing Wound care products not, as required wound be carried out debridement again, sterilization, drain and carry out topical remedy and naturopathy at any time.
8, when protecting wound; Can be as using transparent membrane dressing to fixedly secure the conduit difficult drop-off relevant separately with wound; Its conduit prevents that in the displacement of skin surface conduit from damaging conduit infusion wound because of displacement in the time of overcoming independent use transparent membrane dressing again.
9, as required can waterproof, also ventilative, can isolate external environment again and pollute.
10, can reduce the frequency of changing Wound care products, reduce medical treatment cost.
