Description
本发明属于医疗器械技术领域,更具体地说,是涉及一种可持续灌注引流管。
现在社会中,人们不健康的生活方式,生活压力的增加以及缺乏运动等多种原因,导致高血压性脑出血已成为一种常见病及多发病。该病具有高发病率、高死亡率、高致残率的三高特点。而且高血压性脑出血,其颅内出血部位约80%发生在基底节区,而基底节区为重要神经中枢传导纤维通过的区域,因此,高血压性脑出血常造成病人不死即残的状况,所以,利用合理的医疗器械进行高血压性脑出血的有效治疗具有非常重要的意义。
以往临床对于高血压性脑出血疾病,多采用开颅手术方式进行治疗,这种方式由于需要开颅,手术中在清除脑内血肿的同时,会不同程度的造成脑组织的损伤。近年来,临床上多采用微创手术方式进行治疗,即使用颅脑引流管进行颅内血肿穿刺引流,该方法不仅可以迅速地将脑内血肿引流出来,也不会造成对脑组织的额外损伤,并具有病人恢复快、费用低、病人脑功能容易恢复等优势,因此,该方法得到了广泛的应用。
随着手术方式以及引流手术器械的发展,单管单腔引流管已难以满足病患对引流效果的需求。随即出现了单管多腔以及单管多子管等引流管,如有的引流管通过在总管中设置多个子管,并通过在总管前部设置子管伸缩孔,使得子管可以伸出或缩回到总管中,当子管前部伸出总管时,可实现多点给药引流,从而加快血凝块的溶解和引流速度,进而快速解除血肿对于主要功能结构的压迫,降低高血压脑出血疾病造成的危害。
但是这种引流管由于具有多点给药的多个子管,在外径尺寸相当的情况下势必会牺牲引流腔直径,导致引流速率下降,提升堵管风险。同时,注入药物需要与血肿有一定的反应时间,药物还未与血凝块充分反应便从引流口引出,影响血凝块的溶解和引流速率,多次的人工给药又会带来感染风险。
本发明实施例的目的在于:第一方面,提供一种可持续灌注引流管,用以解决现有技术中引流管引流腔小,引流速率低的技术问题。
为解决上述技术问题,本发明实施例采用的技术方案是:
第一方面,提供了一种医用引流管,包括管体以及与所述管体连通且位于所述管体后端的后插管,所述管体内沿其长度方向具有相互隔离的引流腔及灌注腔,所述后插管包括与所述引流腔连通的第一分支管以及与所述灌注腔连通的第二分支管,所述管体的前端设有多个与所述灌注腔连通的出液口,所述管体的侧壁上还设有与所述引流腔连通的引流口,所述引流口与多个所述出液口之间具有间距。
与现有技术相比,本发明实施例提供的可持续灌注引流管的有益效果在于:相较于现有技术中的单管多子管的引流管,在管体内设置相互隔离的引流腔及灌注腔,实现引流和灌注独立,可在同等直径的条件下具有更大的引流腔,提高引流速率,降低堵管风险,且在引流腔横截面相当的情况下比现有的引流管具有更小的直径,能减轻对脑组织的挤压,减小创伤;在管体前端通过与灌注腔连通的多个出液口实现多点给药,增加药物与血肿接触面积,高效溶解血肿,同时,通过灌注腔持续进行灌注相比一次性给药增加药物与血肿的接触时间,更加有效的溶解血肿,利于引出体外;同时,在距离出液孔一定间距处设置引流口,使得药物充分与血肿反应,利于发挥药效,提高溶解速率,缩短引流管留置时间,减小穿刺感染风险,对预后也有积极意义。

为了说明本发明所述的技术方案,以下结合具体附图对本发明提供的一种可持续灌注引流管的实现通过具体实施例进行详细说明。
实施例一
参照图1,本发明实施例一提供的可持续灌注引流管,包括管体10以及与管体10连通且位于管体10后端的后插管,管体10内沿其长度方向具有相互隔离的引流腔11及灌注腔12,后插管包括与引流腔11连通的第一分支管20以及与灌注腔12连通的第二分支管30,管体10的前端设有多个与灌注腔12连通的出液口40,管体10的侧壁上还设有与引流腔11连通的引流口13,引流口13与多个出液口40之间具有间距。
本发明实施例中,相较于现有技术中的单管多子管的引流管,在管体10内设置相互隔离的引流腔11及灌注腔12,实现引流和灌注独立,可在同等直径的条件下具有更大的引流腔11,提高引流速率,降低堵管风险,且在引流腔11横截面相当的情况下比现有的引流管具有更小的直径,能减轻对脑组织的挤压,减小创伤;在管体10前端通过与灌注腔12连通的多个出液口40实现多点给药,增加药物与血肿接触面积,高效溶解血肿,同时,通过灌注腔12持续进行灌注相比一次性给药增加药物与血肿的接触时间,更加有效的溶解血肿,利于引出体外;同时,在距离出液孔一定间距处设置引流口13,使得药物充分与血肿反应,利于发挥药效,提高溶解速率,缩短引流管留置时间,减小穿刺感染风险,对预后也有积极意义。
进一步地,本实施例中,引流口13与距离最近的出液口40之间有一定的间距,间距可为15mm-20mm。通过对引流口13位置的上述设置,使得药物进入血肿部位能与血肿有充分的作用时间,达到溶解血肿的目的,然后再由引流口13引出体外。
具体地,多个出液口40包括位于管体10的前端端部的多个第一出液口41以及位于管体10的前端侧壁的多个第二出液口42。多个第一出液口41呈发散状分布;多个第二出液口42沿前端长度方向多点分布,同时沿周向均匀分布。通过多个第一出液口41与多个第二出液口42从多个方向对血肿的多个部位进行持续给药,提高血肿溶解引流效率。
进一步地,第一分支管20端部还设有用于连接外部导管的鲁尔接头(图中未示出)。第一分支管20通过鲁尔接头连接到外部引流管路上,将血肿收集到无菌的引流袋中。
进一步地,第二分支管30端部还设有肝素帽31。第二分支管30通过肝素帽31接入灌注器,灌注器的药物通过灌注腔12、出液口40持续输送到血肿部位,提升血肿溶解效率。
本实施例中,引流口13为一个,当然,引流口13也可以为两个,或更多。当引流口13为两个或更多时,多个引流口13沿管体10长度方向间隔设置。
本实施例中,第一分支管20与第二分支管30通过管接头50连接于一体。通过管接头50将第一分支管20与第二分支管30进行有效固定,便于手术时操作。
实施例二
参照图2,本发明实施例提供的可持续灌注引流管与实施例一中可持续灌注引流管的不同之处在于,管体10内还设有球囊腔14,球囊腔14与引流腔11、灌注腔12平行设置,在管体10的前端还设有与球囊腔14连通用于注入液体的定位球囊15,后插管还包括与球囊腔14连通的第三分支管60,第三分支管60上设有单向阀61。
引流管根据血肿清除情况一般会留置5-7天,在引流过程中的护理,防止引流管脱出尤为关键。本实施例中,当引流管穿刺到位后,用注射器向单向阀61内注入适量生理盐水,使生理盐水通过球囊腔14到达定位球囊15,使定位球囊15充盈起来,从而将引流管固定在脑组织沟回处,从而起到固定引流管的作用,避免引流管脱出,降低感染或重新插管等风险。
具体地,定位球囊15注入液体后的直径范围为15mm-20mm。
进一步地,在第三分支管60上还设有指示气囊62,指示气囊62与定位球囊15连通,可监测定位球囊15是否出现泄漏等,降低引流管脱出风险。
本实施例中,为了便于固定,第一分支管20、第二分支管30及第三分支管60通过管接头50连接于一体。
另外,本实施例中,引流口13为两个,两个引流口13沿管体10长度方向间隔设置。
本实施例的其他结构与实施例一相同,此处不作赘述。
以上仅为本发明的优选实施例而已,并不用于限制本发明。对于本领域的技术人员来说,本发明可以有各种更改和变化。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的权利要求范围之内。
