Description

一种适用于控制取卵过程中恒定流速抽吸卵泡液的操作台
技术领域
本实用新型涉及一种生物科技医疗辅助设备,具体涉及一种适用于控制取卵过程中恒定流速抽吸卵泡液的操作台。
背景技术
在体外受精(In Vitro Fertilization)是指哺乳动物的精子和卵子在体外人工控制的环境中完成受精过程的技术,英文简称为IVF。由于它与胚胎移植技术(ET)密不可分,又简称为IVF-ET。在生物学中,把体外受精胚胎移植到母体后获得的动物称试管动物(test-tube animal)。这项技术成功于20世纪50年代,在最近20年发展迅速,现已日趋成熟而成为一项重要而常规的动物繁殖生物技术引。
取卵作为体外受精-胚胎移植过程中重要的手术操作之一,取卵过程的顺利性也影响体外受精-胚胎移植的结局。常规取卵是在穿刺取卵过程中通过操作人员目测流速以调整压力大小抽吸卵泡液获得卵子的过程,在这过程中,流速无法控制。当存在个体差异时,即在相同的压力下,流速的快和慢均会造成卵子的机械性损伤,从而影响受精及卵裂,故监测及制定合适的流速能更好的保存卵子的活力。
实用新型内容
本实用新型的目的是针对上述现状,提供一种适用于控制取卵过程中恒定流速抽吸卵泡液的操作台,以解决现有通过预估流速设定压力抽吸卵泡液的缺陷。
本实用新型采用的技术方案:一种适用于控制取卵过程中恒定流速抽吸卵泡液的操作台,包括流量检测传感器、流量控制装置、数据显示屏和开关,所述流量检测传感器、数据显示屏、开关分别与所述流量控制装置连接,所述流量检测传感器与卵泡液导管连接,用于检测该卵泡液导管内的卵泡液的流速,所述流量控制装置与负压吸引器连接,用于控制所述负压吸引器的压力大小,从而控制所述卵泡液导管内的卵泡液的流速达到设定值,所述数据显示屏用于实时显示当前卵泡液的流速、设定流速、总容量和总时间,所述开关用于控制所述流量控制装置的开启和关闭。
本技术方案的效果是:该适用于控制取卵过程中恒定流速抽吸卵泡液的操作台利用流量检测传感器获取的流速,流量控制装置根据设定流速控制负压吸引器压力大小,保证在取卵过程中保持恒定的流速,不会对卵子造成机械损伤。
进一步地,所述流量检测传感器非接触式安装在所述卵泡液导管上。
进一步地,述开关为脚踏开关。
附图说明
图1所示为本实用新型提供的一种适用于控制取卵过程中恒定流速抽吸卵泡液的操作台的结构示意图。
具体实施方式
以下结合附图对本实用新型的原理和特征进行描述,所举实例只用于解释本实用新型,并非用于限定本实用新型的范围。
请参阅图1,为本实用新型提供的一种适用于控制取卵过程中恒定流速抽吸卵泡液的操作台的结构示意图,其包括流量检测传感器1、流量控制装置2、数据显示屏3和开关4。流量检测传感器1、数据显示屏3、开关4分别与流量控制装置2连接。
流量检测传感器1与卵泡液导管连接,用于检测该卵泡液导管内的卵泡液的流速。具体地,流量检测传感器1非接触式安装在该卵泡液导管上。
流量控制装置2具有加压和减压输出信息,从而使卵泡液导管内的卵泡液的流速达到设定的值。流量控制装置2与外部的负压吸引器连接,用于控制该负压吸引器的压力大小。流量控制装置2具有PID整定算法,能快速稳定地控制该负压吸引器,保持恒定流速。
数据显示屏3用于实时显示当前卵泡液的流速、设定流速、总容量、总时间等相关信息。
开关4用于控制流量控制装置2的开启和关闭。具体地,开关4为脚踏开关,通过脚踏开关4来控制流量控制装置2的启停,如此可以单人完成取卵冲洗操作。
本操作台的原理如下:利用流量检测传感器1实时检测卵泡液的流速,流量控制装置2获得该流速后,与设定的流速进行比较,通过PID控制算法控制该负压吸引器压力大小改变流速,最终达到与设定值一样大小的恒定流速。
具体操作如下:在取卵前,将取卵针、取卵管安装完毕,将流量检测传感器1装在该取卵液导管上,设定好流速,踩下脚踏开关4,在穿刺卵泡过程中流量控制装置2根据流速控制该负压吸引器保持恒定流速,同时相关的数据显示在数据显示屏3上。
如此,该适用于控制取卵过程中恒定流速抽吸卵泡液的操作台利用流量检测传感器1获取的流速,流量控制装置根据设定流速控制负压吸引器压力大小,保证在取卵过程中保持恒定的流速,不会对卵子造成机械损伤;通过脚踏开关控制注射装置,单人可以完成取卵过程。
以上所述仅为本实用新型的较佳实施例,并不用以限制本实用新型,凡在本实用新型的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。
