技術說明

本發明係揭露了一種精蟲篩選系統及其方法。其概念是藉由靜水壓差來形成一穩定的流場，並藉著精子本身可以抵抗流場的特性分出各層級活動力的精蟲，再利用速度層級分選來有效篩選出不同活動力的精蟲。利用此流道設計，可以快速且有效地找出具有強活動力的精子。另一方面，本發明的其中之一特徵在於本發明之待測精子係自始設置於系統之入口處，而非出口處。再者，本發明亦得選擇性地增設有一激活設計，用於激活受冷藏儲存影響的精子。 The present invention discloses a sperm selecting system and the method thereof. The brief concept of the present invention is to generate a flow field by hydraulic pressure difference then utilize the property that the sperm swims against the flow field so as to difference the sperms by vitality thereof. One of the main features of the present invention is that the sperms be selected are initially disposed at the entrance of the flow field instead of the exit of the system. Furthermore, an activating design can be selectively added to the present invention so as to activate the sperm be affected by the process of freeze storing.
