Description

一种可置入人体血管和体腔内的导管 A catheter into a body cavity and human blood vessels

技术领域 FIELD

[0001] 本发明涉及一种医疗器械,尤指一种可以置入人体血管和人体腔内(胸腔和腹腔) 的导管。 [0001] The present invention relates to a medical instrument, particularly to a human body and human blood vessels can be placed in cavities (pleural and peritoneal) catheter. 属于医疗器械技术领域。 Belonging to the technical field of medical instruments. 背景技术 Background technique

[0002] 置入长期血液透析导管是需要长期血液透析患者的一个重要透析路径。 [0002] placed in long term hemodialysis dialysis catheters is an important path of the long-term hemodialysis patients. 血液透析导管长时间置入可导致导管的部分堵塞,进而影响血液透析过程的透析血液流量,或在血透时出现导管贴壁现象。 Hemodialysis catheters into long portion of the catheter may cause blockage, thereby affecting the dialysis blood flow during hemodialysis or adherent phenomenon occurs catheter hemodialysis. 此时,血液透析医生常常将原有的动脉和静脉血路互换,这样可以保证有效的透析血液流量。 In this case, doctors often hemodialysis existing arterial and venous Road interchange, so you can ensure effective dialysis blood flow. 但是,由于以往的血液透析导管采用双腔血液通路的一长和一短设计,即动脉血路与导管的长管相连,静脉血路与导管的短管相连,这样在进行血液透析时,静脉血路回流的是未经血液透析处理过的血液,而经血液透析处理过的血液则经长管动脉通路流回人体。 However, since the conventional hemodialysis catheters using a short and a long blood access dual lumen design, i.e. arterial road is connected to the catheter long tube, connected to the blood path of the catheter tube is shorter, so that when performing hemodialysis, venous reflux passage hemodialysis is not treated blood, and treated blood via hemodialysis arterial access is via a long tube back into the body. 当导管出现堵塞时,原有的动脉和静脉血路互换,血液透析处理过的血液则经短管通路流回人体,则有较多经透析处理过的血液经长管通路进入透析的静脉血路,导致部分血液反复进入透析器内,进而影响血液透析的效率和效果。 When the catheter blockage, arterial and venous blood original road interchange, hemodialysis treated blood back into the body passage through a short pipe, there is more blood treated by dialysis over a long tube into the venous passage path dialysis , resulting in some of the blood enters the dialyzer is repeated, thereby affecting the effectiveness and efficiency of hemodialysis.

[0003] 如果我们将导管的两条通路设计同一长度,并将中间隔板向前突出,将近半圆的导管管壁部分去除,当使用导管同时进行液体的输入和输出时,可使流进液和流出液之间的交换程度最小;血液透析时动、静脉血路的互换,血流可有效地冲刷导管来减少血栓形成。 [0003] If we designed two paths of the catheter same length, and the intermediate partition plate projecting forward and nearly semicircular wall portion of the catheter is removed, when the catheter while input and output of the liquid, the liquid can flow into the exchange between minimum and effluent; movable hemodialysis, venous road interchange of the blood flow can be effectively flushing the catheter to reduce thrombosis. 在非血透期间,血流可经缺损区域流入,再经导管口流出,可以减少血栓发生。 During non-hemodialysis, blood may flow through the defect area, and then out through the conduit opening, thrombosis can be reduced. 发明内容 SUMMARY
