Description

一种用于血管介入的输液器辅助设备及输液器系统
本申请要求于2022年10月27日提交专利局、申请号为2022228506175、申请名称为“输液器辅助设备及输液器系统”的专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及血管介入医疗器材技术领域，具体涉及神经介入、心血管介入、外周介入等操作所用的一种用于血管介入的输液器辅助设备及输液器系统。
背景技术
在神经介入、心血管介入、外周介入等血管介入治疗过程中，可能需要同时使用到多个输液器对介入导管进行冲洗，防止导管内血栓形成闭塞导管或远端血管栓塞事件发生。例如：神经血管介入脑动脉瘤栓塞治疗中，股动脉鞘管、指引导管、中间导管、支架微导管、弹簧圈栓塞导管5支导管均需要肝素生理盐水冲洗，大多血管介入需要使用3-5根输液器冲洗导管。输液器包括瓶塞穿刺器、输液管、滴壶、滴速控制器等，输液器的数量过多，输液管悬空悬挂，导致操作台杂乱，输液器之间不宜区分，滴壶液滴不宜观察，术者或助手对需要调节的输液器调节滴速、置换接头、关闭管道带来困难，为手术操作的风险控制带来障碍。
此外，由于导管冲洗用输液器的数量较多，输液瓶大多呈圆形分布挂在输液架上，导致部分滴壶被其他输液管、其他滴壶遮挡，不易观察到所有的滴壶液体滴速。每个冲洗用输液器滴速靠手动控制，滴速靠主观估计，滴速控制器滑脱可能导致滴速过快，液体进入导管过度，增加肺水肿风险。
本发明目的为研制一种用于血管介入的输液器辅助设备及输液器系统，提供标识清晰、排列有序、直观易观察的冲洗用输液器排布系统，并提供自动电子调节滴速及故障异常报警系统，为血管介入操作提供冲洗便利，提高介入手术的安全性和有效性。

在一些血管介入治疗场景中，需要同时使用到多个冲洗用输液器对介入导管进行冲洗，例如，神经血管介入脑动脉瘤栓塞治疗中，股动脉鞘管、指引导管、中间导管、支架微导管、弹簧圈栓塞导管5支导管均需要肝素生理盐水冲洗，大多血管介入需要使用3-5根输液器冲洗导管。输液器包括瓶塞穿刺器、输液管、滴壶、滴速控制器等，输液器的数量过多，输液管悬空悬挂，导致操作台杂乱，输液器之间不宜区分，滴壶液滴不宜观察，术者或助手对需要调节的输液器调节滴速、置换接头、关闭管道带来困难，为手术操作的风险控制带来障碍。本发明目的为研制血管介入所需冲洗用输液器辅助设备及输液器系统，提供标识清晰、排列有序、直观易观察的冲洗用输液器排布系统，并提供自动电子调节滴速及故障异常报警系统，为血管介入操作提供冲洗便利，提高介入手术的安全性和有效性。
请参阅图1，本申请提供了一种用于血管介入的输液器辅助设备100，所述输液器辅助设备100包括底板10及固定座20。
底板10可呈板状，其形状不做具体的限定。可选的，底板10呈矩形。本申请对于底板10的体积不做具体的限定。可选的，底板10的体积相对较小，例如宽195mm*高110mm*厚4mm。输液器辅助设备100还包括横杆，横杆的长度为200mm。底板10后面(背离固定座20的面)上方设有横杆连接点，以便于后续安装发光盒(发光盒在后续说明)，在神经血管介入治疗中，利用介入手术杆固定使用。
所述固定座20凸设于所述底板10。底板10与固定座20可一体成型。固定座20的形状不做具体的限定。可选的，固定座20呈矩形。
为了便于描述，定义图1中X轴方向为固定座20的宽度方向(前后方向)，Y轴方向为固定座20的长度方向(左右方向)，Z轴方向为固定座20的高度方向(上下方向)。
所述固定座20具有相背设置的顶面201、底面202以及连接于所述顶面201与所述底面202之间的侧面203。所述侧面203与所述底板10相背设置。所述顶面201朝向顶侧，即Z轴正向，所述底面202朝向底侧，即Z轴反向。所述侧面203朝向前侧，即X轴正向。
请参阅图1及图2，所述固定座20设有多个沿第一方向排列的固定孔21。第一方向为Y轴方向。每个所述固定孔21皆至少用于收容一次性医用输液器200的滴壶210。本申请对于固定孔21的数量不做具体的限定，例如，固定孔21的数量可以为2个、3个、4个、5个、6个或6个以上等。
固定孔21沿Z轴方向设置，使滴壶210沿竖直方向设置。可选的，固定孔21可大致呈圆柱形。
请参阅图1及图2，所述固定孔21贯穿所述侧面203并在所述侧面203形成第一开口211，所述第一开口211沿所述第一方向的尺寸(宽度)大于或等于所述输液管220的外径且小于所述滴壶210的外径，以便于连接所述滴壶210底部的输液管220经所述第一开口211进入所述固定孔21。
请参阅图1及图3，所述固定孔21贯穿所述顶面201并在所述顶面201形成第二开口212，所述第二开口212连通所述第一开口211，所述第二开口212的尺寸大于或等于所述滴壶210的外径，以让滴壶210可从固定孔21的上方放置于固定孔21内。
请参阅图1及图4，所述固定孔21贯穿所述底面202并在所述底面202形成第三开口213，所述第三开口213连通所述第一开口211，所述第三开口213的尺寸大于或等于所述输液器200的输液管220的外径且小于所述滴壶210的外径，以便于输液器200的输液管220可贯穿第三开口213，及使固定孔21的底壁可托举所述滴壶210，使滴壶210容置于固定孔21内。
先将所述滴壶210底部的输液管220经所述第一开口211进入所述固定孔21，再将滴壶210从固定孔21的上方进入固定孔21中，直至滴壶210的底部抵接于固定孔21的底壁，实现滴壶210设于固定座20的固定孔21中，通过上述的方式将多个输液器200的滴壶210分别设于不同的固定孔21内，以整理不同输液器200的输液管220和滴壶210，以利于快速给需要的输液器200调节滴速、置换接头、关闭管道，还避免了部分滴壶210被其他输液管220、其他滴壶210遮挡，以便于观察到所有的滴壶210液体滴速。
本实施例提供的固定座20上设了5个排列整齐的固定孔21，可整理1-5个输液器200，便于输液器200整理使用。
第一开口211可作为观察滴壶210内的液体和滴速的观察窗口。本申请对于观察窗口为沿Z轴方向设置的长条矩形。本申请对于观察窗口沿Y轴方向的宽度不做具体的限定，例如10mm。第一开口211的宽度小于所述滴壶210的外径，以避免设于固定孔21内的滴壶210从第一开口211移出。
本申请对于第二开口212的尺寸不做具体的限定。可选的，第二开口212的尺寸可大于所有规格的滴壶210外径，以便于所有规格滴壶210均可从上方插入固定孔21，本申请提供的输液器辅助设备100可搭配所有输液器200使用。
可选的，第二开口212的直径为25mm(但不限于该尺寸)，可兼容常用不同厂家的输液器200，兼容性强。
本申请提供的用于血管介入的输液器辅助设备100通过在固定座20上设置多个依次排列固定孔21，固定孔21的第一开口211的尺寸大于或等于所述输液管220的外径且小于所述滴壶210的外径，以便于连接所述滴壶210底部的输液管220经所述第一开口211进入所述固定孔21，该固定孔21的第二开口212的尺寸大于或等于滴壶210的外径，以让滴壶210可从固定孔21的上方放置于固定孔21内，固定孔21的第三开口213的尺寸大于或等于所述输液器200的输液管220的外径且小于所述滴壶210的外径，以托举所述滴壶210，如此，使固定孔21可收容输液器200的滴壶210，由于固定孔21依次排列，则可将多个输液器200的滴壶210依次排列，进而将多个输液器200的滴壶210、输液管220梳理整齐，有效解决输液器200的数量过多，导致操作台杂乱，输液器200之间不宜区分，给术者或助手调节滴速、置换接头、关闭管道带来困难的问题。
可选的，请参阅图4，所述第三开口213包括承托口213a和导向通道213b。所述承托口213a与所述第二开口212同心设置。可选的，承托口213a、第二开口212可皆为圆形。承托口213a的中心与第二开口212的中心共线且该共线沿Z轴方向设置。
所述承托口213a的尺寸大于或等于所述输液管220的外径且小于所述滴壶210的外径。可选的，所述滴壶210的底部可以设于承托口213a内，以将滴壶210固定于固定孔21内。当固定孔21的内径大于滴壶210的外径时，通过将滴壶210的底部设于承托口213a内，可将滴壶210固定于固定孔21内，防止滴壶210在固定孔21内倾斜或不稳定。
可选的，承托口213a的内壁可呈圆锥形，以与滴壶210的底部外轮廓面相贴合，以提高滴壶210在固定孔21内的稳定性。
可选的，承托口213a可为圆柱形孔，直径为10mm(但不限于该尺寸)。承托口213a可承托所有规格的滴壶210下端，便于固定所有规格的滴壶210。
所述导向通道213b连接于所述承托口213a与所述第一开口211之间。所述导向通道213b沿所述第一方向的尺寸大于或等于所述输液管220的外径且小于所述承托口213a的尺寸。所述输液管220经第一开口211进入固定孔21后还经导向通道213b进入承托口213a。
举例而言，所述导向通道213b的宽度方向的尺寸为3mm(但不限于该尺寸)，便于输液管220通过。
本申请对于导向通道213b的延伸方向不做具体的限定。可选的，导向通道213b可沿X轴方向设置。
可选的，所述导向通道213b偏离于所述承托口213a的几何中心设置。所述导向通道213b的中线与所述承托口213a的几何中心不共线，使设于承托口213a内的输液管220不易经导向通道213b移出，提高固定孔21的收容稳定性。
请参阅图4，所述导向通道213b偏向承托口213a的右侧圆周切线，避免输液管220直接从导向通道213b牵拉出来。
当然，在其他实施方式中，所述导向通道213b还可以呈倾斜方向延伸、或沿弯折线方向延伸或沿曲线方向延伸等等，使设于承托口213a内的输液管220不易经导向通道213b移出，提高固定孔21的收容稳定性。
可选的，所述第一开口211沿所述第一方向的尺寸大于所述导向通道213b沿所述第一方向的尺寸。
一般地，输液器200的材质大多无色透明化工材料制作，常用介入导管灌洗液为无色透明生理盐水，导致滴壶210中液滴、液平分辨不清，可能导致滴速过快心脏负荷过重、空气进入血管内致空气栓塞风险。
本申请提供的输液器辅助设备100还能够清楚地分辨滴壶210中液滴、液平。
具体的，请参阅图1及图5，所述底板10设有多个沿所述第一方向依次排列的透光孔101，每个所述透光孔101连通一个所述固定孔21。其中，透光孔101呈长条形，沿Z轴方向设置。
请参阅图5，所述输液器辅助设备100还包括光源盒30。光源盒30设于底板10背离所述固定座20的一侧。光源盒30内设有多个发光件31。所述发光件31设于所述底板10背离所述固定座20的一侧，每个所述发光件31皆通过所述透光孔101朝向所述固定孔21内发光。
可选的，发光件31包括但不限于为LED灯珠、LED灯条等。可选的，发光件31发射的光线为白光。
本申请对于透光孔101的尺寸不做具体限定，可选的，透光孔101沿Y轴方向的宽度为3.5mm，透光孔101沿Z轴方向的高度为50mm。
请参阅图5及图6，所述输液器辅助设备100还包括多个透光玻璃40。每个所述透光玻璃40设于一个所述透光孔101内。即透光玻璃40嵌设于所述透光孔101内。
请参阅图5及图6，所述透光玻璃40包括拼接的无色透光玻璃41和有色透光玻璃42。所述有色透光玻璃42相对于所述无色透光玻璃41靠近所述第三开口213。本申请对于无色透光玻璃41和有色透光玻璃42的连接边界不做具体的限定。可选的，有色透光玻璃42的面积大于无色透光玻璃41的面积。例如，透光孔101的上方部分设置15-20mm高的透明玻璃、透光孔101的下方部分设置30-35mm高的有色玻璃。
所述有色透光玻璃42用于至少与所述滴壶210底部(下部)的液体相对设置。无色透光玻璃41用于与所述滴壶210上部的液滴相对设置。
有色透光玻璃42为有一定颜色且透光的玻璃。发光件31发射的光线中的一部分经有色透光玻璃42射向滴壶210的液体，利用液体的折射现象，可清晰地观察滴壶210中液体高度，此时液体呈现有色透光玻璃42的颜色。发光件31发射的光线中的另一部分经无色透光玻璃41射向滴壶210的液滴，可清晰地观察滴壶210中的液滴。
进一步地，至少两个所述透光孔101内的所述有色透光玻璃42的颜色不同，使至少两个滴壶210内的液体可呈现不同的颜色，可能使用颜色：红、绿、蓝、紫、橙。
可选的，每个透光孔101内的有色透光玻璃42的颜色不同，使每个滴壶210内的液体可呈现不同的颜色，以便于区分不同的输液器200。
可选的，相邻的两个透光孔101内的有色透光玻璃42的颜色不同，使相邻的两个滴壶210内的液体可呈现不同的颜色，以便于区分相邻的两个不同的输液器200。
