创伤教科发明背景 Background of the Invention trauma UNESCO

1. 发明領域 1. Field of the Invention

本发明涉及一种铜伤教料,更特iW是涉及具有改善的皮腴錄着牲 The present invention relates to a teaching material injury copper, iW More particularly it relates to an improved skin having a rotund lu sacrifice

以及吸收能力的錄构的创伤象料,以及其产生方法. Absorption capacity and configuration of a recording material as wound, and a generating method thereof.

2. 相关执水的讨谗 2. The enforcement of water-related discussion slander

历史上,使用各种来錄的很多不两的材科通过采用一些类嫿的吸收材料吸收来自饬口处的飭口流体以及组织(在下文中称之为渗出物)来处理伤口.最近几年,日益流行使用基于聚合物的伤口护理产品,来控制伤口处的环境离素例如水蒸气、氣气渗透性、细錄不透过性以及吸收渗出物.这些伤口护理产品被特制以满足特殊的需求包括与身体部分的适应性(conformab鹏ty)、选挣性粘附到伤口层以及对 Historically, many of the various not to record two families of materials (hereinafter referred to as exudate) wound treated by the use of absorbing material absorbing classes tranquil ordered fluid and tissue from the ordered port at the mouth. Recent years, the increasingly popular use of polymer-based wound care products, to control the environment at the wound from factors such as water vapor, gas vapor permeability, impermeability, and fine recording absorb exudate. the wound care product is tailored to meet the special requirements include adaptability (conformab Peng ty) of the body part, make the election of the adhesive layer to the wound as well as

两銑伤口处的皮肤的錄着性. Recorded with two milling skin at the wound.

最近,闭合教料或保湿教料在处理伤口,特JN是祷疮和清疾方面逐渐被接受.本领域6知多种类型的錄构可用于或作为闭合教^K遢常包括接收、吸收以及保曹渗出物的成分.典藝地,这些伤口护理产品包括聚合物泡涞材料、聚合物薄廣、顆粗以及纤维状聚合物、水凝胶以及水状胶体(liydnK:olloid).具有上述至少一种成分的教料通过提供湘湿环境、并除去过重渗出物以及有毒成分来促进伤口禽合,并进一步作为屏陣保护伤口免于鍵发細菌感染.虽然这些已知的闭合创伤敷料能有效地处理伤口,但是发现很多闭合教料具有一些局限性或缺点. Recently, a closed teaching material or humectant teach materials have been gradually accepted in the treatment of wounds, Patent JN is prayer sores and cleared disease aspect skilled 6 known various types of recording configuration may be used in or as close to teach ^ K messy typically includes receiving, absorbing and ingredient Paul Cao exudates Code arts, these wound care product comprises a polymeric foam material Lai, a polymer thin wide, thick and fibrous polymer particles, hydrogels, and hydrocolloid (liydnK: olloid) having. said at least one component material taught by Gordon providing a wet environment, and removal of exudates and toxic heavy component to promote wound birds together, and further protect the wound from a front panel keys with bacterial infection. Although these known closure the wound dressing can effectively treat the wound, but found that many materials have some limitations closed teach or disadvantages.

在伤口护理方面,创锈敦科的一个主要的轉的是増加、提离或是最大限度地利用教料的吸收能力,从而减少或消除漫软,促进伤口的禽合过程.如果要保持伤口的小环境,头等重要的是控制渗由物.不幸的是,发现很多创伤教料除去了伤口产生的所有的渗出物,从而产生一个"干"伤口,这在伤口禽合过租中是不希望有的,或者发现这种创伤款料不能充分地吸收或控制渗出物,从而导致渗出物汇集起来,这就增加了細俯肇脈的危隆以及导致感染. In wound care, creating a major rust Duike turn to increase in the lift-off or maximize the absorption capacity of the teaching material, to reduce or eliminate soft diffuse, promote wound avian lamination process. If you want to keep the wound small environment, the first important thing is to control the infiltration by the substance. Unfortunately, a lot of trauma was found to remove all of the teaching material wound exudate produced, resulting in a "dry" wound, which together had rented in poultry is wound unwanted, or found that trauma material shall not fully absorb exudate or control, resulting in a pooled exudate, which increases the risk of fine veins overlooking the Chao Lung and lead to infection.

现有技术的很多创伤教料包括具有吸收性能的吸收层.典型地, Many prior art wound teaching materials include absorbent layer typically has absorption properties,

吸收层含有亲水材料,该亲水材料錄吸收渗出物并使邻伤教料在其往 Absorbent layer comprising hydrophilic material, the hydrophilic material absorb exudate and recorded ortho material wound thereon to teach

置保留几天时间.该吸收屋可以含有非织造材料或含有水状胶!Mfc^ Set retention days. The absorbent nonwoven material may contain a house or contain aqueous gum! Mfc ^

的泡沐材料,例如美鹏专利4j373,S19和6,566,576中描述的教料,或亲水泡沫屋,例如美鹏专利5,409,472、 S,7M,787、 6,0柳,492 、 6,051,747 以及6,486,378中鏞迷的教料. Mu bubble material, for example, U.S. Patent No. Peng 4j373, S19 and 6,566,576 teach materials described, or hydrophilic foams house, for example, U.S. Patent No. Peng 5,409,472, S, 7M, 787, 6,0 Liu, 492, 6,051,747 and 6,486,378 in Yong fans teach material.

虽然吸收簾教料被设计成吸收伤口渗出物,但它们通常具有能吸收的渗出物的量有限的缺点.吸收性泡沫材料的最大吸收限度暹常与它们在吸收液体曾的几何大小直接相关.例如亲水泡沫材料只能扩大为原始大小的12-15%.另一缺点是由于差的液体保留性,己经发现 Although the curtain teach absorbent material is designed to absorb wound exudate, but they typically have a limited amount of energy absorbed exudates disadvantages maximum absorption limit Siam absorbent foam material is often geometric in which they had direct absorption liquid related. such as hydrophilic foams expanded only 12-15% of the original size. another disadvantage is due to the difference in liquid retention, we have found

一定量的渗出物被"桥出"吸收性泡沫材料救料.渗出物从泡沐层被桥出,从而从教料本身被桥出的可能性具有引起感染的危险,以及妨碍伤口禽合. Amount of exudate is "a bridge" absorbent foam materials save material. Mu exudate from the blister layer is a bridge, so that a risk due to the possibility of infection from the teaching material bridge itself, and hinder wound birds together .

已知的教料其有的另一缺点是通过与伤口接触的吸收层吸收渗出物,导致使用的教料的中夹部分膨胀并推压伤口.持续的雄脒能引起粘着皮肤的屉与伤口区城外面的皮肤分离,特刺是在创伤教料釣边界处,在此会产生"巻边"效应.创伤敷*的过度»胀进一步导歃渗出物从教料的外S渗漏,从而为致病樣生物的入侵提供通道,并进一步促使伤口处漫软. Teach any known material which is obtained by further disadvantage absorbing layer in contact with the wound exudate absorbed, resulting in the folder material used to teach partially expanded and pushes the wound. Amidine male sustained drawer can cause adhesion of the skin with outside the city area separated from the skin wound, trauma taught in Laid-stab material catch at the boundary, this will produce a "side Volume" effect. excessively wound dressing * »bulge further outer guide suck exudate leakage teaching materials from S, thereby providing a passage for the invasion of pathogenic organisms like, and further to promote wound diffuse soft.

传统上,提供有背村层,该背村层包括附着到吸收屋以眯止渗出物从教料渗漏的不透液体薄農.在吸收流体过程中产生困难,闳为当吸收性核心膨胀时,背村层必須客纳吸收层的脚胀而不导致教料巻边.美頃专利4,738»257中梯迷了一种试爾解决该问趙的方法,该专利公开了由薄弹性板构成的背衬层,当吸收性核心雄胀时,它能够弯曲.然而已经发现不透液体的褒料燧不能充分地伸展,以与吸收层的膨胀保持一致,錄果阻碍吸收层膨脉的薄廣就在教料的边缘产生上迷的舂边.美頃专利6,040,492提出了另一种解决方法,该专利公开一种创伤教料,该教料包括附着到吸收性泡沫材料核心的背衬层,并且背村层包括多个補缺,当泡沫材料核心雄胀时,褶缺基本上变平.虽然背衬屉能容纳泡沫材料核心的雄胀,但该创伤教料的流体吸收受到 Conventionally, there is provided a back village layer, the backing layer comprises a village housing attached to the absorbent to exudate impermeable blind stopper from leakage of liquid feed teachings thin AGRICULTURAL difficulties arise in the course of absorbing fluid, the absorbent core expands when Xiahong , the backing layer must foot swelling village off satisfied absorbing layer without causing side Volume teachings material. US Patent No. 4,738 are »ladder fans 257 a method of solving this test Seoul Zhao Q, which discloses a thin elastic plate composed of the backing layer, the absorbent core when the male inflation, it can be bent. However, it has been found praise liquid impervious material Sui not sufficiently stretched, expanded to conform to the absorbent layer, the absorbent layer recording fruit hinder expansion veins thin broad teaching material on the edge side Chung generating fan. US Patent No. 6,040,492 are proposed another solution, which discloses a wound teaching material, the teaching material is attached to a core comprising an absorbent foam material backing layer, and the backing layer comprises a plurality of filled villages, the foam core when the male swelling, lack of substantially flattened pleats. while backing tray to accommodate expansion foam core male, but the wound fluid absorbing material taught by

泡沫材料核心本身的膨胀性限制.a此,由于泡沫材料中心部有限的 Foam core itself expandable .a this limit, due to the limited central portion of the foam material

吸收能力,需要经常更換教料. Absorption capacity, the need for frequent replacement of teaching materials.

理想的是,刮伤教料本廣上必须是,錄性的,a此它可以附着到 Ideally, the scratch teach this material must be widely recorded of, a this it can be attached to

伤口处,并且是无毒以及只是引发最低限度的过敏反应.此外,创伤教料应该具有防止細禱从周國环境进入伤口的能力,两时提供速宜的水分传输速率. Wound, and is non-toxic and caused only minimal allergic reactions. In addition, the material should have the ability to teach trauma fine prayer into the wound from the environment to prevent Zhou, should provide moisture-speed transmission rate of two o'clock.

然而,已经发现,很多已知的闭合教料的缺点是只是依靠用于将款料爾定到皮肤上的压教箱附层,例如具有离特异粘着性的丙錄酸瞎胶.典型的,当从伤口上被除去时,只具有錄合粥的,伤教料具有从伤口剩掉教料的中夹都分的趙势,闳此可能類害禽合组织. However, it has been found that many materials known drawback is that the closure taught merely to rely on models for a given material to the press Seoul teach tank attachment layer on the skin, for example, a plastic blind propionic acid recorded from specific tackiness. Typically, when removed from the wound, only recorded together with the porridge, teaching material wound off from the left with a wound clip teaching materials are divided potential Zhao, Hong this class may harm avian SCO.

创伤教料&经可以商购获得,该,伤款料包括具有伤口接触表面的吸收性泡沫材料核心部,该伤口接触表面涂有一条砼氣统凝鼓.硅氣就凝鼓沿吸收性泡涞材料的部分孔壁随机布置,形成多个随机形成的錄咪.当没有爾化的碰氣就凝狡施加到泡沫材料核心部时,暹过毛细管作用形成所述錄昧.该方法的一个缺点在于硅氣就凝胶可以封闭一些孔,另一缺点在于这些孔是酸机形成的,这可能导致局部区域抑 & Taught by trauma materials are commercially available, which, wound section comprises an absorbent foam material core portion having a wound contacting surface of the wound contacting surface is coated with a concrete air system condensate drum on a silicon gas condensate drum of the absorbent foam Lai portion of the hole wall material randomly arranged to form a plurality of recording microphone formed at random when no touch of Seoul gas condensate to be applied to the foam core cunning portion by capillary action is formed Siam ignorant of the recording. a method of silicon dioxide is disadvantageous in that some of the gel pores can be closed, another disadvantage in that the acid of the holes are formed, which may lead to local area suppression

4W泡沫材料核心部吸收渗出物.虽然在一些应用中想要提供一种创伤教料,在其选定的区械内具有更大浓度的縫昧,从而增加该区域对渗出物的吸收,但是该方法不适和这种形成预定田案的錄據.此外,该方法的另一缺点在于硅氣就在的表面粗棘度很大程度上取决于待涂袭的泡沫材料表面,在想要得到一种贴在皮肤上的光滑硅氣烷层的情况下,该方法不能得到逸种先滑的磁氣坑层. 4W foam absorbent core exudates. While desirable to provide a wound material taught in some applications, having a greater concentration of ignorant slits in its armed selected region, thereby increasing the absorption of the exudate region , but the method is not formed and recorded according to a predetermined field of this case. Furthermore, another disadvantage of this method is that the surface roughness of the silicon dioxide is in the ratchet depends largely on the foam surface to be coated of the passage, thinking to obtain a smooth lower alkoxy silicon layer of one gas attached to the skin of the case, the method can not obtain a magnetic layer pit Yi to slippery species.

The absorbent core can be desirable to rapidly absorb exudate to enhance the effectiveness of teaching materials of the present invention, in particular the fluid-absorbent with an insertion hole to house the absorbent material. in addition to the absorbent, want an efficient capillary action, i.e. the absorbent core can be quickly guided wave member away from the absorbent core for storage near surface to more Yi City area (i.e. jack comprising discontinuous portions of the absorbent material), so that the local saturation of the absorbent core down and the passage of low performance is maximized.

优选的吸收性核心由至少稍樣亲水的乘性开孔泡沫材料构成.适 The absorbent core preferably consists of an open cell foam material by at least slightly hydrophilic like. Suitable

宜的泡沫材料的开孔尺寸为滩至7柳槺米,优逸开孔尺寸为邻到3脚徵米.开孔允许将流体和细應碎片传逃到泡沫材料中并在泡沫材料中传送,优选泡沫材料区域的开孔尺寸具有足够的大小,从而促进毛细管作用并促进流体传送. Hole size of the foam is desirable to beach 7 meters Liu Kang, Yi opening size preferably is adjacent to pin 3 characterized meters apertures allow fluid and small debris pass should escape the foam in the foam conveying and , hole size region foam material preferably of sufficient size to facilitate capillary action and facilitate fluid transfer.

当被流体铯和时,吸收性核心可以库雎原有大小的大约135^. 当与本发明的表面屋和背村条相錄合时,当充满渗出物时,吸收性核心仅可以膨胀到其千尺寸的大约110%. When cesium is about 135 and the fluid when the absorbent core can library Ju ^ original size. When the surface of the housing and the back bars of the present invention village with timely recording, when filled with exudate, the absorbent core can expand only its size one thousand to about 110%.

根据本发明的一个实施方案,在吸收性核心犀度的方向上吸收泡沫材料包含有开孔尺寸梯度,使得开孔尺寸在远表面和吸收性核心的方向上减小.由于开孔尺寸在以及靠近吸收性核心的近表面上较大, According to one embodiment of the present invention, in the direction of the absorbent core of the absorbent foam material rhino with hole size gradient, such that the opening size decreases in the direction of the distal surface and the absorbent core. Since the opening size and near the surface of the absorbent core close to a larger,

More capillary force management, this near trapped near the surface of the absorbent core and negative fluid movement toward the fluid receptacle. Additionally, absorbent foam material may comprise a gradient towards the opening size of the jack, thereby providing absorbent foam materials are toward the insertion hole is designed to have a local region of a capillary force to be increased, for directing fluid towards the.

泡沫材料可以由,例如聚A糖、纤雉素、欺化丁二烯-笨乙蜂樣鼓、 聚醋泡沫材料、亲水性环氣泡沫材料或聚丙鋒酸瞎构成.在优选的实施方案中,泡沫材料由亲水性聚A糖泡沫材料构成,例如由Reynel Inc.(Bootliliay,ME)生产的产品标号为L00562-B的聚IMtt泡沫材料. 由于上迷泡沫材料本身是亲水的,此外考虑到含有吸收材料的插孔的应用,在优选的实施方案中不需要处理该泡沫材料以使其更亲水. Foam material may be formed, for example, poly A sugar, fiber prime pheasant, bullying butadiene - bee-like drum Ben acetate, polyester foams, hydrophilic or polypropylene foam ring gas front blind acids constituting a preferred embodiment of the the foam material is made of hydrophilic poly a sugar foam, for example Reynel Inc. (Bootliliay, ME) products designated IMtt polyethylene foam L00562-B Since the above-foamed material itself is hydrophilic, Further consideration of the application to the jack comprising absorbent material, in a preferred embodiment does not need to process the foam to make it more hydrophilic.

在另一实施方案中,如果需要,可以对泡沫材料进行处理使其更亲水,从而增强渗出物在泡沫材料中更迅速凝结的趁势,而仅达到泡沫材料不能太亲水以致泡沫材料的亲水性阻碍滲出物传逸到吸收性材料中的程度.在该实施方案中,可以设计吸收性泡沫材料亲水性的水平,使得表面张力最小,从而允许流体容易进入泡沫材料孔.当伤口处保持相对离的湿度的同时,流体能这样保留在吸收泡沫材料中. In another embodiment, if desired, may be treated to make it more hydrophilic foam material, thereby enhancing exudates more rapidly in the foam condensation taking advantage of, and only reach a foam material that can not be too hydrophilic foams obstruction hydrophilic exudate to pass Yi extent of the absorbent material. in this embodiment, the level may be designed hydrophilic absorbent foam material, such that the minimum surface tension, allowing fluid to readily enter the foam pores. when wound while maintaining the relative humidity from, so that the fluid can be retained in the absorbent foam material.

可以理解,吸收性核心不限于由泡沫材料构成.在另一实施方案中,吸收性核心可以是使用本领城技术人贝可得到的已知材料通过很多方法生产的多孔织造或非织造材料.例如,吸收性核心可以作为一种由非常短的纤维素纤维以建机或非建机布置构成的宽大、柏素成形的织物,纤維素薄片垫,或聚合物原纤維基廣而存在.

The depth of each jack is generally for the Smni , the surface soil layer from at least 0.5mm. in this embodiment, the case of the field to be rounded in Mei

教料的特定区域比其它区械包括更多的插孔. Teach a specific area other than the material region comprises additional mechanical jack.

困11显示的嚇伤教料的一个实施方案中,吸收性核心14的中心部分比教料10边缘部分24附近具有更离密度的插孔18.吸收槺核心的任何特定区城的插孔的数量取决于局部会有更大量的流体的可察竟区域,例如在中心都分,以使流体吸收最大化,此外限制在吸收性核心的特定区域内,例如逸缘都分吸收流体. 11 threatened a storm damage embodiment shown in teaching material, the central portion of the absorbent core 14 having any particular density region from the city more receptacles 18. Kang absorbent core material than teaching receptacle portion 10 near the edge 24 depends on the local number will be a greater amount of fluid actually observed region, for example, are divided in the center, in order to maximize the absorption of fluid, in addition to limiting the absorbent core in a specific area, e.g. Yi edge points are absorbing fluid.

如田2所示,将插孔18设置成在吸收性核心14的iML面上开口, 并向整个厚度延伸一定距离.在优选的实施方案中,插孔延伸聚离t, 比吸收性核心18的整个犀度t要短,优选插孔延伸的距离为吸收性核心14的总厚度的709C-90%.然而可以理解,在创伤教料的一个实施方案中,插孔可以延伸穿过吸收性核心的整个厚度. As shown in field 2, the jack 18 is arranged on the surface of the absorbent core 14 iML opening and extends a distance the entire thickness. In a preferred embodiment, the receptacle extending from poly t, than the absorbent core 18 t of the entire rhino shorter, extending from the receptacle is preferably 709C-90% of the total thickness of the absorbent core 14. It will be appreciated, however, in one embodiment the wound teaching material, the receptacle may extend through the absorbent the entire thickness of the core.

在创伤教料的另一实施方案中,插孔18可以被设直成,如困13 所示,根振它们的位置以及局都存在的来自伤口处的流体渗出物,向吸收性核心14的厚度延伸不同的距离.在该实施方案中,更靠近教料10中心的插孔18向吸收性核心14的厚庋延仲得更深,而更靠近吸收性核心边缘24的插孔18比中心部分22的插孔18向吸收性核心14的厚度延仲的距离要浅.由此更深的插孔18比更浅的插孔18含有更多的吸收材料20,从而提供更大的局,吸收区域. In another embodiment of the wound teaching material, the receptacle 18 may be set to a straight, as shown, the root of their position transducer 13 and trapped there bureau fluid exudate from the wound to the absorbent core 14 thickness extending different distances. in this embodiment, the teaching material is closer to the center of the insertion hole 10 of the absorbent core 18 to the thickness 14 of the extension Gui secondary deeper, and closer to the absorbent core edge 24 of the receptacle 18 than the center 18 of the socket portion 22 extending from the thickness of the secondary absorbent core 14 to be shallower. jack 18 thus deeper than the lighter receptacle 18 to contain more absorbent material 20, thereby providing greater Bureau, absorbent region.

由于优选插孔只是部分延伸至吸收性核心的总厚度,困此将通过吸收材料传送并吸收渗出物.这种結果使没有插孔的吸收性核^的近表面处于理想的湘湿环境,渗出物不会过量铯和,从而允许敷科在伤口处保持更长的时阀. Since the insertion hole preferably extending only partially to a total thickness of the absorbent core, the difficulties of this exudates absorbed by the absorbent material and transfer. This result is not the absorbent core jack ^ near-surface in humid environment over Xiang, not in excess exudate and cesium, thereby allowing the valve is maintained for a longer branch cladding at the wound.
