Description

一种血液透析导管
技术领域
本发明涉及医疗器具技术领域，具体而言，涉及一种血液透析导管。
背景技术
血液透析是治疗急慢性肾功能衰竭的主要治疗手段，在自体静脉内瘘成熟前，多采用血液透析导管作为患者的血管通路，血液透析导管置入部位有颈内静脉和股静脉，一般需要在人上使用3个月左右，目前采用的是传统胶布固定，因颈部和腿部活动幅度大，极易出现缝线断裂导致血液透析导管滑脱，患者又需重新插管，不仅增加了患者痛苦，又增加了患者医疗费用。
发明内容
本发明的目的在于提供一种方便固定、固定可靠的血液透析导管，以解决上述问题。
为实现本发明目的，采用的技术方案为：一种血液透析导管，包括管体、基板、固定块、滑块；固定块与滑块在基板上相对设置，且固定块固定设置，滑块沿朝向固定块的方向滑动设置；管体穿过基板，固定块与滑块的相对面分别设置有与管体相匹配的弧形槽；滑块的弧形槽两侧设有调节柱，调节柱上轴向排布有多个凸卡，基板的弧形槽两侧设有与调节柱配合的限位孔；管体上设有流速调节器，管体的末端设有流量显示计。
进一步地，所述滑块的底面设有沿其滑动方向设置的凸条，凸条的截面为燕尾形，基板上开设有与凸条相匹配的滑槽。
进一步地，所述滑块背离固定块的表面中部为弧形凹面
进一步地，所述固定块的弧形槽与所述管体贴合。
本发明的有益效果是，滑块与固定块在管体的两侧，只需一手把在滑块与固定块的外侧，将滑块向固定块方向滑动，即可通过二者相对面的弧形槽对管体进行包覆固定，调节柱和凸卡与限位孔之间的配合卡紧实现调节固定，容易控制，不会造成引流管滑动或引流管堵塞现象，固定非常可靠，不会松动，方便可靠。
附图说明
图1是本发明提供的血液透析导管的主视图；
图2是图1中血液透析导管的A-A剖视图；
图3是图1中血液透析导管的侧视图。
具体实施方式
下面通过具体的实施例子并结合附图对本发明做进一步的详细描述。
图1、图2、图3示出了本发明提供的血液透析导管，包括管体9、基板1、固定块2、滑块3；固定块2与滑块3在基板1上相对设置，且固定块2固定设置，滑块3沿朝向固定块2的方向滑动设置；管体9穿过基板1，固定块2与滑块3的相对面分别设置有与管体9相匹配的弧形槽；滑块3的弧形槽两侧设有调节柱4，调节柱4上轴向排布有多个凸卡5，基板1的弧形槽两侧设有与调节柱4配合的限位孔6；管体9上设有流速调节器10，管体9的末端设有流量显示计11。
滑块3的底面设有沿其滑动方向设置的凸条7，凸条7的截面为燕尾形，基板1上开设有与凸条7相匹配的滑槽。滑块3背离固定块2的表面中部为弧形凹面8，方便人手操作。
固定块2的弧形槽与管体9贴合，固定块2的弧形槽与基板1中部的管体9安装孔平齐，这样在滑块3移动过来后能够很好的贴靠固定。多个凸卡5即对应多个调节位置，限位孔6内同样也对应凸卡5有卡槽。基板1的两端连接有弹性绷带，弹性绷带的端部设有粘扣。
固定块2与基板1可为一体式结构，即形成L形的整体固定块，塑料一体成型。流速调节器10方便的控制血流速度，再通过管体9末端的流量显示计11能够及时检测到血液透析管的状况，帮助医务人员快速做出判断，及时发现堵塞或其它异常状况。
以上所述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，在本发明的精神和原则内可以有各种更改和变化，这些等同的变型或替换等，均包含在本发明的保护范围之内。
