一种外科创面封闭式负压弓I流装置 A surgical wounds closed suction flow means bow I

技术领域 FIELD

[0001] 本发明涉及一种医疗用品,尤其是一种外科封闭式负压引流装置。 [0001] The present invention relates to a medical supplies, particularly a surgical closed suction drainage device. 背景技术 Background technique

[0002] 负压封闭引流技术(vacuum sealing drainage/VSD,简称VSD技术)的概念最早由德国ULM大学Fleischmarm博士于1992年首创,并形成六轮雏形,用于四肢创面的引流。 [0002] concept of vacuum sealing drainage (vacuum sealing drainage / VSD, VSD technology for short) was first pioneered by Dr. Fleischmarm Germany ULM University in 1992, and the formation of six prototype for wound drainage limbs. 1997年,Morykways等研究发现该装置可以促进伤口创面局部血液循环,促进岗位芽组织生成,减少组织细菌含量,提高皮瓣或游离植皮存活率。 In 1997, Morykways et al found that the apparatus may facilitate wound bed local blood circulation, promote post shoot tissue generation, tissue reduce bacterial content, improve skin graft or skin flap survival. 后来Moues等证实,负压封闭引流技术与传统的湿润敷料包扎相比,显著缩短伤口愈合时间。 Later Moues other confirmed, the conventional vacuum sealing drainage compared to wet dressing, the wound healing time was significantly shortened. i^baian通过试验研究发现负压引流与高压氧治疗相比更能促进肉芽组织增生;Couttefangeas发现伤口充填的辅料上浸润的细胞主要为粒细胞成分,CD4(+)功能T细胞可以促进创面内的清洁,提供良好的微环境。 i ^ baian Experimental study found that drainage and negative pressure hyperbaric oxygen therapy to promote the proliferation of granulation tissue compared to more; Couttefangeas found infiltrating cells on a wound filling materials mainly granulocytes component, CD4 (+) T cell function can promote the wound clean, provide a good microenvironment. Labanaris等2009年研究发现VSD可以促进创面周围组织淋巴管网的增生。 Labanaris and other 2009 study found that VSD can promote the proliferation of lymphatic tissue surrounding the wound pipe network. 越来越多的学者通过大量的研究和临床实践证实了VSD技术的临床应用效果,并将其理论研究不断改进,2003年德国、奥地利等国将该技术纳入创口治疗指南。 More and more scholars through extensive research and clinical practice confirmed the clinical application effect VSD technology, continuous improvement and theoretical research, in 2003 the country Germany, Austria and other technology into the wound treatment guidelines.

[0003] 负压封闭引流技术是指用内含有负压引流管的聚乙烯酒精水化海藻盐泡沫敷料(VSD辅料),来覆盖或填充皮肤、软组织缺损的创面,再用生物半透膜对之进行封闭,使其成为一个密闭空间,最后把负压引流管接通负压源,通过可控制的负压来促进创面愈合的一种全新的治疗方法。 [0003] VSD technology is polyvinyl alcohol foam dressing hydration alginates (VSD materials) comprising the inner suction drainage tube to cover or fill in skin, wound and soft tissue defects, then the biological semipermeable membrane for the closing, making it a closed space, and finally the source of negative pressure suction drainage tube is turned on, the negative pressure may be controlled to facilitate a novel method of treating a wound healing. 在我国VSD技术已广泛适用于:创伤科、骨科、普外科、烧伤科等领域。 In our country VSD technology has been widely applied to: the field of traumatology, orthopedics, general surgery, burn and so on.

[0004] 现有的VSD技术基本配置包括负压源(包括医用吸引机、医院使用的中心负压装置或负压引流瓶),负压引流管,聚乙烯醇泡沫或其它医用多孔泡沫、海绵或纱布(简称多孔敷料)、可粘帖密封用的透气薄膜、接头(包括二通接头、三通接头或多通接头)、引流容器寸。 [0004] The basic configuration of the prior art comprises the VSD negative pressure source (suction unit including a medical center or a negative pressure suction drainage bottle device used in hospitals), suction drainage tube, polyvinyl alcohol foam or other medical porous foams, sponges or gauze (the porous dressing), a breathable film may be pasted with the sealing joint (including two-way connection, through three joints or fittings), the drainage container inch.

[0005] VSD技术是将传统的负压引流方法与封闭性敷料相结合的产物,它通过在创面形成负压,产生机械和生物学效应,促进创面愈合。 [0005] VSD is the traditional technique suction drainage method occlusive dressing product of the combination, which is formed by a negative pressure in the wound, producing mechanical and biological effects, and promote wound healing. 因此必须使用专用的创面填充敷料,现有的创面填充敷料多孔敷料,它要求内部要保持通畅,以确保负压吸引出的组织能被正常吸出,常用材料为聚乙烯醇,且要求泡沫微孔直径在0. 2-1. Omm,而聚乙烯醇成本高,制造工艺复杂,目前主要依赖于进口,同时每个患者治疗所需的数量较多,造成此类治疗方法成本很高,给患者增加了沉重的经济负担。 Must use a dedicated filling wound dressings, conventional wound dressings filled porous dressing, it is required to keep them open inside, to ensure that the suction can be sucked out of the normal tissue, commonly used material is polyvinyl alcohol, and the required foam cells diameter of 0. 2-1. Omm, polyvinyl alcohol and the high cost, complex manufacturing process, mainly dependent on imports, while each of the larger number of patients required, resulting in high cost of such therapy, the patient increased financial burden. 因此,开发一种低成本的替代产品是当务之急。 Therefore, the development of a low-cost alternative is a priority.

[0006] 在此基础上,本发明人发明了一种外科创面封闭式负压引流用创面填充敷料及制备方法,其创面填充敷料用丝瓜筋替代聚乙烯醇,降低了成本,但是,这种外科创面封闭式负压引流用的创面填充敷料为固定的,一次性的,将其填充敷料敷在伤口上,如果想观察皮肤的愈合情况,撕开创面的填充敷料,观察完后,需更换填充敷料,填充敷料不可以反复使用;其次,采用的是有源机械式的负压,携带不方便;再次,丝瓜筋填充敷料在使用过程中, 易被腐蚀。 [0006] On this basis, the present invention invented a surgical wound closed with wound suction drainage and filling dressing preparation, their filling wound dressings loofah Alternatively polyvinyl alcohol, reduces the cost, but this surgical wounds closed wound suction drainage filled with a fixed dressing, disposable, which is deposited in the wound dressing is filled, if you want to observe the healing of the skin, tearing wound dressing filled, after observation, to be replaced filling the dressing, the dressing can not be used repeatedly filled; Secondly, the negative active mechanical inconvenient to carry; again, loofah filled dressing during use, susceptible to corrosion.
