Description
技术领域 technical field
本实用新型涉及医疗器械技术领域,具体地,涉及一种负压封闭引流装置。 The utility model relates to the technical field of medical equipment, in particular to a negative pressure sealing drainage device. the
背景技术 Background technique
负压封闭引流技术(VSD)是指用内含有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。 Vacuum sealing drainage technique (VSD) refers to the use of polyvinyl alcohol hydrated seaweed salt foam dressing (VSD auxiliary material) containing drainage tubes to cover or fill the wounds of skin and soft tissue defects, and then use biological semipermeable membranes to treat them. It is closed to make it a closed space, and finally the drainage tube is connected to a negative pressure source, which is a brand new treatment method to promote wound healing through controllable negative pressure. the
实施VSD所需的材料包括1、医用泡沫:是直接置入被引流区的部分,是一种泡沫型聚乙烯酒精水化海藻盐泡沫敷料(PVA泡沫),色白,海绵样,质地柔软富有弹性,抗张力强,其内密布大量彼此相通的直径0.2~1.0mm的空隙,有极好的可塑性和透水性及良好的生物相容性2、引流管:多侧孔引流管:德国B.Braun公司生产的CH14-18多侧孔硬质硅胶引流管,长50cm,其一端14cm范围内有密集的侧孔,引流时把多侧孔引流管穿入医用泡沫内,现有已穿入CH-18多侧孔引流管的医用泡沫供应,使用方便。3、透性粘贴薄膜:美国3M公司生产的透明敷料,其成分为聚安脂,是一种具有分子阀门作用的透性黏贴薄膜,成品装在无菌塑料袋内,供一次性使用。用以封闭被引流区域使与外界隔绝;4、负压源:提供引流动力,保证被引流区内应被引出物的引出。 The materials needed to implement VSD include 1. Medical foam: it is a part directly placed in the drained area. It is a foam-type polyvinyl alcohol hydrated seaweed salt foam dressing (PVA foam), white in color, sponge-like, soft and elastic in texture , strong tensile strength, densely covered with a large number of gaps with a diameter of 0.2 to 1.0mm that communicate with each other, with excellent plasticity, water permeability and good biocompatibility 2. Drainage tube: multi-side hole drainage tube: Germany B.Braun The CH14-18 multi-side hole rigid silicone drainage tube produced by the company is 50cm long and has dense side holes within 14cm at one end. Medical foam supply of 18 multi-side hole drainage tubes, easy to use. 3. Permeable adhesive film: The transparent dressing produced by 3M Company in the United States is composed of polyurethane, which is a permeable adhesive film with molecular valve function. The finished product is packed in a sterile plastic bag for one-time use. It is used to seal the drained area to isolate it from the outside world; 4. Negative pressure source: provide drainage power to ensure the extraction of the things that should be drawn out in the drained area. the
VSD的特点是:1)可控制的负压,促进血流量增长和蛋白合成,促进肉芽生长,加快创面愈合;同时为全方位的主动引流提供了动力。2)生物半透膜的 封闭,隔绝了创面与外环境接触的感染机会。3)全方位的引流,是将传统的点状或局部引流,变为了面状引流,保证了能随时将创面的每一处的坏死组织和渗出液,及时排除体外。 The characteristics of VSD are: 1) Controllable negative pressure can promote blood flow growth and protein synthesis, promote granulation growth, and accelerate wound healing; at the same time, it provides power for all-round active drainage. 2) The sealing of the biological semipermeable membrane isolates the chance of infection between the wound surface and the external environment. 3) All-round drainage is to change the traditional point or local drainage into surface drainage, which ensures that the necrotic tissue and exudate in every part of the wound can be removed from the body in time. the
使用VSD的优点如下:1)治疗时间明显缩短,减少病人痛苦,并减轻工作量。病人免除换药之苦,医生免除换药之劳。2)有效地避免交叉感染VSD是在一个密闭的系统内进行,负压引流使引流区的渗出物和坏死组织被及时清除,3)高效、全方位、零积聚,保证引流效果促进创面血运采用持续负压吸引的方法,变被动引流为持续主动吸引,不留任何腔隙,其压力的高低基本符合生理条件的要求,故不影响血运。更重要的是,持续负压吸引促进了创面组织的体液向引流管方向不断流动,为创面的血运提供了有效的、持续的、辅助的动力。4)避免死亡。 The advantages of using VSD are as follows: 1) The treatment time is significantly shortened, the pain of the patient is reduced, and the workload is reduced. Patients are exempted from the pain of changing dressings, and doctors are exempted from the labor of changing dressings. 2) Effectively avoid cross-infection VSD is carried out in a closed system. Negative pressure drainage enables the exudate and necrotic tissue in the drainage area to be removed in time. The method of continuous negative pressure suction is adopted to change passive drainage into continuous active suction without leaving any cavity. The level of pressure basically meets the requirements of physiological conditions, so blood supply is not affected. More importantly, the continuous negative pressure suction promotes the continuous flow of body fluid in the wound tissue to the direction of the drainage tube, providing effective, continuous and auxiliary power for the blood supply of the wound. 4) Avoid death. the
在我国VSD技术已广泛用于:创伤科、烧伤科、普外科、骨科等领域。 VSD technology has been widely used in our country: traumatology, burns, general surgery, orthopedics and other fields. the
但是,在VSD技术使用过程中极容易造成引流堵塞,究其原因为:1、被引流区域内的坏死组织过多或大量的粘稠引出物,超出引流管的处理能力。2、密封薄膜密封不严,造成负压环境的丧失,引流管内的液体或小颗粒不会被吸引而抽入引流容器,并在引流管内凝固形成一段干涸的引出物堵塞引流管。3、密封薄膜密封不严,使多孔泡沫软垫脱醇变硬,造成多孔泡沫软垫失去引流作用。4、创面清理不完全,如未完全止血等。 However, it is very easy to cause drainage blockage during the use of VSD technology. The reasons are as follows: 1. There is too much necrotic tissue or a large amount of viscous elicited matter in the drainage area, which exceeds the processing capacity of the drainage tube. 2. The sealing film is not tightly sealed, resulting in the loss of the negative pressure environment. The liquid or small particles in the drainage tube will not be attracted and drawn into the drainage container, and will solidify in the drainage tube to form a section of dry lead to block the drainage tube. 3. The sealing film is not tightly sealed, which makes the porous foam cushion dealcoholized and hardened, causing the porous foam cushion to lose its drainage function. 4. Incomplete wound cleaning, such as incomplete hemostasis. the
为了解决上述技术问题,中国专利文献CN201529311U公开了内置带冲洗管的引流管的泡沫软垫结构。该专利在在引流管中内置一个侧壁带有侧孔的冲洗管,冲洗管穿过引流管的后端管壁并引出。 In order to solve the above technical problems, Chinese patent document CN201529311U discloses a foam cushion structure with a drainage tube with a flushing tube built in. This patent has a flushing tube with a side hole in the built-in drainage tube, and the flushing tube passes through the rear end tube wall of the drainage tube and is drawn out. the
该专利文献CN201529311U固然解决了一部分引流管堵塞的问题,然而,利用水冲洗堵塞的引流管,冲洗力度不够,不但不能解决堵塞的问题,冲洗液也会渗 漏到创伤面,造成二次感染。另外,当堵塞频繁发生时,需要频繁冲洗,冲洗液使用过多,不利创伤面保持干燥。 Although this patent document CN201529311U solves the problem of a part of the drainage tube clogging, yet, the drainage tube that is blocked by flushing with water is insufficient in flushing force, not only cannot solve the problem of clogging, but also the flushing fluid will leak to the wound surface, causing secondary infection. In addition, when blockage occurs frequently, frequent flushing is required, and excessive flushing fluid is used, which is not conducive to keeping the wound surface dry. the
