Description
技术领域technical field
本发明涉及一种人体伤口引流医用耗材，具体地说是一种三腔负压伤口冲洗引流管。The invention relates to a medical consumable material for drainage of human wounds, in particular to a three-chamber negative pressure wound irrigation and drainage tube.
背景技术Background technique
现今伤口引流管多为单腔引流管，难以将伤口深部脓液和分泌物完全引流出来。因为引流管较软难以置入伤口深部，负压吸引由于管腔内无支撑容易造成管腔闭塞，单腔管更不能用于冲洗伤口，如果用单腔管冲会能加重伤口感染或导致混合感染，所以伤口引流效果不好。目前深部伤口的冲洗是由两根独立的管道组成，且引流管为圆形；这样不便于管理引流管，且在引流时由于引流管口周围无支撑很容易被周围软组织堵塞而失效。持续负压引流可以及时将伤口内脓液或分泌物引流出来，同时促进肉芽组织生长，促使伤口愈合。Nowadays, most wound drainage tubes are single-lumen drainage tubes, and it is difficult to completely drain the deep wound pus and secretions. Because the drainage tube is soft and difficult to place deep into the wound, negative pressure suction can easily cause lumen occlusion due to the lack of support in the lumen, and single-lumen tubes cannot be used to rinse the wound. Infection, so the wound drainage effect is not good. At present, the irrigation of deep wounds is composed of two independent pipes, and the drainage tube is circular; it is not convenient to manage the drainage tube, and it is easy to be blocked by the surrounding soft tissue during drainage because there is no support around the drainage tube mouth. Continuous negative pressure drainage can timely drain the pus or secretions in the wound, and at the same time promote the growth of granulation tissue and promote wound healing.

1、三条管道结合为一体，三条管道各有其功能，且集多个功能为一体；主引流管、冲洗管和导丝植入管三个管腔分别起到伤口冲洗、负压引流、导丝置入作用；作为伤口冲洗的主引流管主要用于引流同时伤口冲洗；作为负压引流的冲洗管主要用于导丝负压引流；作为导丝置入的导丝植入管在植入金属导丝后可以增加引流管硬度，使引流管能顺利的植入伤口深部，金属导丝还可以在透视下显影定位，确定引流管深度和位置，导丝置入管也可以在置入引流管后取出金属导丝作为伤口分泌物收集管，以做细菌学检测。1. The three pipelines are combined into one, and each of the three pipelines has its own function, and integrates multiple functions into one; the three lumens of the main drainage tube, the irrigation tube and the guide wire implantation tube are used for wound washing, negative pressure drainage, and guide wire respectively. The effect of wire insertion; the main drainage tube used as wound irrigation is mainly used for drainage and wound irrigation; the irrigation tube as negative pressure drainage is mainly used for guide wire negative pressure drainage; The hardness of the drainage tube can be increased after the metal guide wire, so that the drainage tube can be implanted into the deep part of the wound smoothly. The metal guide wire can also be visualized and positioned under fluoroscopy to determine the depth and position of the drainage tube. The guide wire can also be inserted into the drainage tube After the tube was removed, the metal guide wire was taken out as a collection tube for wound secretions for bacteriological testing.
2、引流管外壁下凹槽处有多个引流开口与主引流管相通，增加了引流面积，增加引流效果；多个引流开口使得伤口从深部到浅部都有负压作用，促进了感染坏死组织的引流，负压状态也促进了伤口从深到浅的肉芽组织形成。2. There are multiple drainage openings in the lower groove of the outer wall of the drainage tube connected to the main drainage tube, which increases the drainage area and improves the drainage effect; multiple drainage openings make the wound have negative pressure from deep to superficial, which promotes infection and necrosis Tissue drainage and negative pressure also promote the formation of granulation tissue from deep to superficial wounds.
3、体内置入引流管截面为四瓣梅花形，四瓣凸起对体内软组织起到支撑作用，防止了负压吸引时周围软组织对引流管引流口的堵塞。3. The cross-section of the drainage tube inserted in the body is four-petal quincunx, and the four-petal protrusions support the soft tissue in the body, preventing the surrounding soft tissue from blocking the drainage port of the drainage tube during negative pressure suction.
4、主引流管截面为四瓣梅花形，增加了引流管壁强度，内侧突起的皱褶起到对管腔的支撑作用，这样在负压引流时防止了管腔的闭塞。4. The cross-section of the main drainage tube is four-petal quincunx, which increases the strength of the drainage tube wall, and the protruding folds on the inner side play a role in supporting the lumen, thus preventing the occlusion of the lumen during negative pressure drainage.
本发明由与人体组织相容性良好的硅胶制成，防止使用过程中出现排异反应。本发明是发明者在多年临床经验基础之上研制的成果，它克服了现有引流管存在的缺点，在伤口引流中能够很好的引流出伤口内脓液和分泌物，同时对感染伤口可以冲洗，也能防止持续负压引流时出现伤口内引流管引流口的堵塞，因有置入导丝使得置入时引流管变硬能很好植入伤口深部，金属导丝可以透视显影，确定引流管深度，这样可以起到很好的准确置入、良好引流、冲洗、防堵塞作用，从而能够良好引流、促进伤口愈合。The invention is made of silica gel with good compatibility with human tissue, preventing rejection reaction during use. The present invention is the result developed by the inventor on the basis of many years of clinical experience. It overcomes the shortcomings of existing drainage tubes, and can well drain pus and secretions in the wound during wound drainage, and at the same time can treat infected wounds. Rinsing can also prevent the drainage tube from being blocked in the wound during continuous negative pressure drainage.

主引流管101、冲洗管102和导丝植入管3三个管腔各自是独立的，相互之间不相通；冲洗管102和导丝植入管103只在引流管头、尾两端开口，与主引流管101不相通；保证引流管完整，维持负压。The three lumens of the main drainage tube 101, the irrigation tube 102 and the guide wire implantation tube 3 are independent and do not communicate with each other; the irrigation tube 102 and the guide wire implantation tube 103 are only open at the head and tail of the drainage tube , not communicating with the main drainage tube 101; ensure the integrity of the drainage tube and maintain negative pressure.
主引流管101的管腔大于冲洗管102和导丝植入管103的管腔。即主引流管101是粗管，冲洗管2和导丝植入管3是细管。The lumen of the main drainage tube 101 is larger than that of the irrigation tube 102 and the guide wire implantation tube 103 . That is, the main drainage tube 101 is a thick tube, and the irrigation tube 2 and the guide wire implantation tube 3 are thin tubes.
本实施例所示体内置入引流管1截面为四瓣梅花形，主引流管101设在四瓣梅花形的中心位置，冲洗管102和导丝植入管103分别设在四瓣梅花形的两个相对花瓣位置；参见图2：主引流管101管腔截面为四瓣梅花形，冲洗管102和导丝植入管103管腔截面为圆形。体外引流管201、体外冲洗管202和体外导丝植入管203的截面为圆形。当然，冲洗管102和导丝植入管103也可以设在相邻排列在两花瓣位置。The cross-section of the intracorporeal drainage tube 1 shown in this embodiment is a four-petal quincunx, the main drainage tube 101 is arranged at the center of the four-petal quincunx, and the irrigation tube 102 and the guide wire implantation tube 103 are respectively arranged at the four-petal quincunx. The positions of two relative petals; see FIG. 2 : the section of the lumen of the main drainage tube 101 is four-petal quincunx, and the section of the lumen of the irrigation tube 102 and the guide wire implantation tube 103 is circular. The cross sections of the extracorporeal drainage tube 201 , the extracorporeal flushing tube 202 and the extracorporeal guide wire implantation tube 203 are circular. Certainly, the flushing tube 102 and the guide wire implantation tube 103 may also be arranged adjacently at two petal positions.
由于体内置入引流管1截面为四瓣梅花形，体内置入引流管1外壁的四处凸起（下凹槽两边为凸起）起到对引流管周围软组织的支撑作用，有效防止了植入体内后软组织对引流管的引流开口105的堵塞。主引流管101内截面为四瓣梅花形，防止了负压引流时主引流管的闭塞，保证了引流管在负压时通畅达到有效引流。Since the cross-section of the drainage tube 1 inside the body is a four-petal quincunx shape, the four protrusions on the outer wall of the drainage tube 1 inside the body (both sides of the lower groove are protrusions) play a role in supporting the soft tissue around the drainage tube, effectively preventing implantation. Blockage of the drainage opening 105 of the drainage tube by the posterior soft tissue in the body. The inner cross section of the main drainage tube 101 is a four-petal quincunx shape, which prevents the main drainage tube from being occluded during negative pressure drainage, and ensures that the drainage tube is unobstructed to achieve effective drainage under negative pressure.
