Description

Skin is with film dressing or paste band
The present invention relates to be used for the plastic sheeting dressing of skin or paste band, it is included in its plastic film layers that has applied binding agent on simultaneously.
The cohesive wound dressing made from the plastic sheeting of vapor pervious, for example OpSite (Britain Smith ﹠amp; Nephew company) or Tegaderm (Minnesota Mining and Manufacturing Company) comprises acrylic-type adhesive binder or kin binding agent.When using repeatedly and removing this binding agent easily and they remove the upper strata (horny layer (the stratum corneum)) of a part of skin together, its result, the dressing of this character may cause skin lesion.Therefore the also bonding securely chaeta of these binding agents can cause pain and discomfort when removing dressing.
The trade mark is Mepitel Gauze dressing also be known in the art, it is attached on the skin with very softish cohesive silicone elastomer (silicone elastomer).A kind of like this silicone elastomer has the bond properties with skin-friendly, and much softer to skin than above-mentioned binding agent.When being taken off, it can not peel the part horny layer off yet.Use the people of this dressing when taking dressing off, will not have the sensation of discomfort or pain.The cohesive of silicone elastomer does not suffer damage because of the removal of dressing, thereby can use repeatedly for several times.
So, be similar to Metipel with adhesion characteristic if be used for the binding agent of plastic sheeting dressing With the adhesive elastomer of silicone elastomer replace, when dressing is used for sensitive skin, will be very favourable particularly.But have a serious problem to be, find this elastomer be attached on the skin with attached to identical intensity is arranged on the plastic sheeting, therefore have such grave danger, promptly elastomer layer or its major part still are retained on the skin when desiring to remove dressing.
An object of the present invention is to want head it off, and the functional film dressing that comprises a soft adhesive elastomer layer is provided.
This purpose is to bring with dressing or subsides with the skin that comprises a plastic film layers according to the present invention to finish, on the one side of plastic sheeting, applied binding agent, it is characterized in that fixedly component that it has a particle form is securely on whole this one side attached to the plastic film layers that has applied the binding agent top layer wholly or in part, and binding agent is made up of softish adhesive elastomer, and elastomer has surface smooth and that do not rupture round fixing component and leaving on the one side of plastic sheeting.Because attached on the plastic sheeting, elastomer will can anchor on the thin film when not having fixedly component adhesive elastomer more strongly by fixing component, still be retained in danger on the skin to avoid when removing dressing elastomer.The pliability and the draftability of plastic sheeting can not reduced to any discernable degree that obtains attached to the fixedly component on the plastic sheeting, these character are very important in the dressing of some types.
In a preferred specific embodiments of the present invention, fixedly component is made up of short fiber, and adhesive elastomer is a silicone elastomer.
In the scheme of a change, fixedly component is by granulometric composition.
Now be that reference describes the present invention, wherein with the accompanying drawing
Fig. 1 is the cross sectional representation according to the plastic sheeting dressing or the skin plaster band of a preferred specific embodiments of the present invention;
Fig. 2 is the explanation of pliability determining instrument.
Wound dressing illustrated among the figure is made up of plastic film layers 1, is coated with one deck adhesive elastomer 2 on its one side down.On the lower surface of fixedly component 3 attached to whole plastic sheeting of loose short fiber form.Using before the elastomer layer 2 fixing component 3 attached to the one side down of layer 1 and play the function that increases the surface area that elastomer contacts with it.Consequently, elastomer will be attached on the thin layer 1 that has fixing component 3, being attached on than it has bigger adhesive force on skin, thereby such dressing for skin can be taken off from safety on the skin, does not separate with thin layer that it adheres to and is retained in danger on the skin and do not have elastomer.
In order to guarantee that the pliability and the draftability of component rear film are unlikely obvious reduction using fixedly, said fixedly component preferably with discontinuous form (promptly not connecting each other) attached on the plastic sheeting.Fixedly component plastic sheeting down the one side on distribution preferably also even relatively, to avoid the fusible localized variation of elastomer to plastic sheeting.
Fixedly component 3 can comprise that length is the cellulose fibre of 0.1-3mm.The method that this fiber is fixed on the thin film 1 is, a gelatinous coating at first is provided on thin layer, then loose fibres disperseed or is sprinkling upon on the said gelatinous layer, for example uses strength to place.Can certainly use other fiber, for example viscose fiber, cotton fiber, polyester fiber, Fypro and other like fibrous.
In addition, fixedly component also can be with the method for for example flocculating or extruding attached on the thin film.
As fixing component,, can use all types of granular materialss that can be fixed on the plastic sheeting in principle though fiber is preferred.In this article, so-called granular materials meaning also has by less than 10 promptly except top said fibrous material -3Mm 3The single individual all material of forming, no matter the shape of said individuality is how.For example granular materials can comprise plastic grain, silicon dioxide, polysiloxanes and similar material.Attached to the said particulate position on the thin layer how the thickness of elasticity (body) layer will surpass particulate full-size, with all granules of assurance clad, no matter.
The cohesive silicone elastomer that the most handy German Wacker Chemie of elastic layer joint-stock company name is called Silgel 612 forms, and also can use other soft cohesive silicone elastomer, hydrogel or soft cohesive PUR but should understand.
Wound dressing certainly is foraminous, when particularly it comprises an absorption pad lamination.
The sterilization of carrying out dressing with some conventional sterilization methods also is fine, for example b-sterilization, steam sterilization or use oxirane disinfection.
Be used for herein " skin-friendly is bonding " and be characterizing and be fit to the special adhesive-bonded form that soft adhesive elastomer that the present invention uses presents.
Dissimilar self-adhesive with comparison similarity is usually used in different types of bonding dressing and surgery creme.The common trait of this sizing material commonly used is the outermost layer that they are attached on dead Skin Cell (horny layer) so securely, so that multi-layer cellular is stripped down from skin by sizing material when taking off bonding dressing.The sizing material great majority of Shi Yonging usually are the sizing materials of acrylic-type now, though also often use PUR and polyisobutylene glue.Under the situation of skin-friendly glue, its needle penetration (it constitutes the assay method of pliability) is in the 7-20mm scope, and the analog value of bonding dressing glue commonly used is lower than 3mm.The mensuration of needle penetration is to use the method based on ASTM D 937 and D 51580, has made some modification.Device therefor is penetrometer PNR 10 (German Sommer ﹠amp; Runge KG).Test subject heavily be 62.5 the gram, comprise heavy 15 the gram cones and have piece number 18-0122 and heavy 47.5 the gram round bars and have piece number 18-0042.Test subject is placed the top of penetrometer perpendicular to the cylindrical cup of containing test material, and the top of cone contacts with the surface of test material.Allow the test subject free-falling enter cylindrical cup then.After 5 seconds, measure the degree that test subject enters test material.The diameter of cylindrical cup is 50mm, and height is 30mm.The packed height of test material is 25mm.
The normally used sizing material of mollielast specific adhesion dressing that has the skin-friendly bond properties and use by the present invention has significantly more weak adhesive bond to skin.Therefore the elastomer that has a skin-friendly bond properties is when containing this elastomeric dressing and be stripped from or tear, and horny layer is without prejudice basically.Although elastomer is more weak adhesive bond, however it set up safety and determine bonding, i.e. the loosening voluntarily danger of dressing is very little, this is because elastic body soft makes it enter skin, and thereby provides bigger effective contact surface.When removing dressing, elastomeric pliability also produces big energy accumulating in elastomer and its carrier, and its result also has relatively determine bonding to skin.
Carried out being intended to measure the experiment of peeling off effect with trial volunteer 10 people, its meaning is to be stripped from the degree that dressing surface, back is covered by cell in dressing.Used 4 kinds of dissimilar creme/dressing, they are Duoderm , OpSite , Leukopore With one applied elastomeric (200g/m 2) non-woven subsides band.The mollielast that the skin-friendly bond property is arranged is the elastomer of a polysiloxanes type.Every experimenter tests with 3 test specimens of every kind of product type, sticks 24 hours.Carry out selectively staining with toluidines to appearing at the lip-deep corneocyte of the dressing that takes off, effect is peeled off in record, measures the percent of cell covering surfaces then.From following table tangible result as can be seen:
Dressing number＜1% in creme/dressing dissection scope-10% 311%
Duoderm 0/30 0/30 30/30
OpS?i?te 0/30 0/30 30/30
Leukpore 10/30 16/30 4/30
Polysiloxanes band 27,/30 3,/30 0/30
In order to become " skin-friendly is fusible ", bonding dressing will have maximum 10% the effect of peeling off under the situation of normal skin.
When taking off, dressing can only have very limited corneocyte number because comprise the dressing of skin-friendly adhesive elastomer, the surface of elastomer layer will be unconverted relatively behind removing dressing, this just makes the dressing of this character to re-use, because its cohesive is not subjected to any discernable infringement that obtains.Drag down the dressing adhesive surface of corneocyte from skin, along with taking off of dressing, will be covered by cell basically, this dressing that is just meaning this kind character can not be attached on the skin when attempting to re-use.Duoderm , OpSite , Leukopore Lose the cohesive of 70-100%, and the loss of skin-friendly bonding dressing is less than 10%.
For bonding dressing or bonding creme are worked effectively, the bonding force of itself and skin must surpass dressing or the suffered load of creme in normal the use.Have now found that, on this problem, generally require bonding force to surpass 0.5N (newton) (peeling off or the subsides band of the wide 25mm that tears is measured from skin) with 135 ° angles, thus the loosening voluntarily danger of dressing will can be not high can not accept.Preferred bonding force will be above 0.8N/25mm.
The dressing paste band is affixed on the Duoderm of health volunteer's the 24 hours mensuration in back , OpSite , Leukopore Bonding force be respectively 1.2,2.2 and 0.8N/25mm.The skin adhesive intensity of used siloxanes subsides band is 1.5N/25mm in above-mentioned disbonded test.
The plastic sheeting that is fit to will comprise polyurethane, though can use other plastics, such as silicone plastics.
