AI Technical Summary
Technical Problem
在反复离心的过程中，势必会对精子造成一定的伤害，比如其数量和活力会明显下降、DNA碎片率会增加，从而直接影响后续卵子受精的效果
Benefits of technology
本实用新型公开的精子捕获装置，基于精子的流动趋化机制设计，通过分选膜和腔室的集成，且分选膜上通孔用于连通两腔室并供精子通过，以借助微流控技术对精子进行高质量且自然的分选和捕获，操作更简单，解决临床上人精子分选过程中通过多次离心操作对精子造成伤害的问题，克服传统的离心法筛选精子操作中造成精子的损伤和丢失；与此同时，通过一个精子捕获装置实现了精子分选和捕获的双重功能，能够最大限度的分选出高质量的精子，为临床上筛选高质量的精子用于后续卵子受精提供了一种有效的解决方案。
