Description

防尿液逆流的止流器 技术领域
本发明涉及医用器材领域技术，尤其是指一种防尿液逆流的止流器。
背景技术
尿液收集器是临床常用的一种医疗器械，主要包括导尿管、尿袋、止流器等器械组成。使用这样结构的尿液收集器对无法正常排尿的病患进行尿液收集时，经常发生伴随性泌尿系统感染。根据有关资料报道 ：泌尿系统感染占医源性感染的60％-70％左右，导尿管伴随性感染中有2％-4％发展为革兰氏阴性菌败血症，全球每年约有3万人因使用导尿管引起泌尿系统感染而死亡，所以现在的尿液收集器都会进行设置防止尿液逆流的止流器。
患者的尿液 ，由导尿管引流出膀胱，经喉管，暂时储存于尿袋。 当患者移动或照顾者进行护理时，残留于尿管或尿袋的尿液，位置高于膀胱时，在位能的引导下倒流回膀胱增加细菌感染的机会。传统的止流器需要人手关上屈曲喉管以减少尿液回流的机会，本止流器能主动于上述时间关闭阻止尿液回流，并设有抗菌涂层进一步减少细菌入侵膀胱的机会。
发明内容
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种防尿液逆流的止流器，其有效解决了现有之止流器需人工关闭，且存在回流的问题。
为实现上述目的，本发明采用如下之技术方案：
一种防尿液逆流的止流器，包括有尿管接头、止流阀以及尿袋接头；
该尿管接头包括有基座、于基座外侧面延伸出的尿管接口以及于基座内侧面延伸出的阀接口，尿管接口与阀接口相贯通；
该止流阀为薄膜材质，且止流阀的内外表面均涂置有杀菌物质，止流阀的前后端面贯穿有流道，该流道具有前端进口和后端出口，该前端进口与上述阀接口相连通，该后端出口呈扁平细缝口；
该尿袋接头的前后端面贯穿有通道，该通道具有前端接口和与尿袋管相连接的后端接口，上述基座与前端接口密封固定连接，上述止流阀位于通道内，且流道的后端出口正对于通道的后端接口。
作为一种优选方案，所述止流阀为一整体一体成型连接结构。
作为一种优选方案，所述止流阀包括有相连通的第一止流阀和第二止流阀；第一止流阀和第二止流阀的内部形成上述流道，第一止流阀的前端进口与阀接口相连通，第一止流阀的后端出口为扁平细缝口；该第二止流阀整体呈扁平状，第二止流阀套设于第一止流阀的后端出口上。
作为一种优选方案，所述第一止流阀的前端内部和后端内部连接处呈Y型形状。
作为一种优选方案，所述尿管接头为宝塔接头，其基座的外表面具有外螺纹，相对应的，前端接口内壁具有内螺纹，外螺纹与内螺纹螺纹配合固定连接。
作为一种优选方案，所述阀接口为圆柱状，对应的，流道的前端进口呈圆形，前端进口套设于阀接口上。
作为一种优选方案，所述尿管接头和尿袋接头均为杀菌材质。
作为一种优选方案，所述尿袋接头包括有主体部和于主体部后端一体延伸出的尾部，上述前端接口位于主体部上，后端接口位于尾部上，尾部的内壁具有与尿袋管相连接的内螺纹。
本发明与现有技术相比具有明显的优点和有益效果，具体而言，由上述技术方案可知：
一、通过采用薄膜材料作为止流阀，且止流阀的内外表面均涂置有杀菌物质，止流阀的流道后端出口呈扁平细缝口，当尿液流经后端出口时，由于薄膜的伸缩性，尿液将后端出口涨开就进行排尿；当尿液完全排出后端出口后，后端出口由于薄膜的伸缩性闭合，防止尿液逆流，避免患者被感染；且本发明结构简单，方便实用，其相较传统的止流器能自动防止尿液逆流。
二、止流阀采用双重阀设计，其包括第一止流阀和第二止流阀，其双重阀的设计，双重保险，确保尿液不会倒流；即使有少量尿液倒流到第二止流阀内，但是尿液的压力太小，无法打开第一止流阀，所以达到完全防止逆流的原理。

具体实施方式
请参照图1至图3所示，其显示出了本发明之第一较佳实施例的具体结构，包括有尿管接头10、止流阀20以及尿袋接头30。
该尿管接头10包括有基座11、于基座11外侧面延伸出的尿管接口12以及于基座11内侧面延伸出的阀接口13，尿管接口12与阀接口13相贯通。尿管连接于尿管接口12上，尿液从尿管接口12进入。
该止流阀20为薄膜材料，如TPE材质等，且止流阀20的内外表面均涂置有杀菌材质，杀菌物质的目的是用在万一还有倒流尿液到尿导，倒流的尿液细菌也会被杀菌物质杀物质杀死，减少感染。止流阀20的前后端面贯穿有流道201，该流道201具有前端进口202和后端出口203，该前端进口202与上述阀接口13相连通，具体而言，阀接口13为圆柱状，对应的，流道的前端进口202呈圆形，前端进口202套设于阀接口13上；该后端出口203呈扁平细缝口；在本实施例中，止流阀20为一整体一体成型连接结构。当患者排尿时，尿液于前端进口202进入流道201后，通过薄膜的特有的伸缩性，后端出口203被尿液涨开，尿液于后端出口203流出；当患者停止排尿时，后端出口203通过薄膜的特有的伸缩性闭合，防止尿液倒流，避免患者被感染。
该尿袋接头30的前后端面贯穿有通道301，该通道301具有前端接口302和与尿袋管相连接的后端接口303，上述基座11与前端接口302密封固定连接，具体而言，尿管接头10为宝塔接头，其基座11的外表面具有外螺纹，相对应的，前端接口302内壁具有内螺纹，外螺纹与内螺纹螺纹配合固定连接。上述止流阀20位于通道301内，且流道201的后端出口203正对于通道301的后端接口303。该尿袋接头30包括有主体部31和于主体部31后端一体延伸出的尾部32，上述前端接口302位于主体部31上，后端接口303位于尾部32上，尾部32的内壁具有与尿袋管相连接的内螺纹。上述尿袋接头30和尿管接头10均为杀菌材质。
详述本实施例的工作原理如下：
当患者排尿时，尿液依次从尿管接口12、阀接口13、前端进口202、流道201、后端出口203和后端接口303流过，当尿液流经后端出口203时，由于薄膜的伸缩性，尿液将后端出口203涨开；当尿液完全排出后端出口203后，后端出口203由于薄膜的伸缩性闭合，防止尿液逆流，避免患者被感染。
如图4和图5所示，为本发明之第二较佳实施例，该实施例的结构与第一实施例的结构基本相同，其不同之处在于：
在本实施例中，止流阀20包括有相连通的第一止流阀21和第二止流阀22；第一止流阀21和第二止流阀22的内部形成上述流道201，第一止流阀21的前端进口与阀接口13相连通，第一止流阀21的后端出口为扁平细缝口，且第一止流阀21的前端内部和后端内部连接处呈Y型形状，Y型导流，其人性化设计，在尿液的压力下自动打开，尿液自然通过；该第二止流阀22整体呈扁平状，第二止流阀22套设于第一止流阀21的后端出口上，当尿液排出后，第一止流阀21自动封闭，第二止流阀22也会自动封闭，其双重阀的设计，双重保险，确保尿液不会倒流。即使有少量尿液倒流到第二止流阀22内，但是尿液的压力太小，无法打开第一止流阀21，所以达到完全防止逆流的原理。
本发明的设计重点在于：
一、通过采用薄膜材料作为止流阀，且止流阀的内外表面均涂置有杀菌物质，止流阀的流道后端出口呈扁平细缝口，当尿液流经后端出口时，由于薄膜的伸缩性，尿液将后端出口涨开就进行排尿；当尿液完全排出后端出口后，后端出口由于薄膜的伸缩性闭合，防止尿液逆流，避免患者被感染；且本发明结构简单，方便实用，其相较传统的止流器能自动防止尿液逆流。
二、止流阀采用双重阀设计，其包括第一止流阀和第二止流阀，其双重阀的设计，双重保险，确保尿液不会倒流；即使有少量尿液倒流到第二止流阀内，但是尿液的压力太小，无法打开第一止流阀，所以达到完全防止逆流的原理。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
