    • An improved nozzle system for a flow cytometer and accompanying methods have been invented for a high efficiency orientation and sorting process of a flat sample and dedicates items such as equine or bovine sperm cells. This improved nozzle system comprises a nozzle (16) with a novel interior surface geometry that can both gently accelerate the cells and can include an elliptical-like, single torsional interior surface element within (c) the nozzle, i.e., a single torsional orientation nozzle (6). The elliptical-like, single torsional interior surface element (e.g.) (8, 9, 10) may have a laminar flow surface and may produce the simplest flow path for applying minimal forces which act in either an accelerative nature or orienting hydrodynamic forces, namely, the single torsional orientation forces, to orient a flat sample (16) such as animal sperm cells into a proper direction for an analyzing and efficiently sorting process in clinical use, for research and for the animal insemination industry.
    • 已经发明了一种用于流式细胞仪的改进的喷嘴系统和相关方法,用于平坦样品的高效取向和分选过程,并且专用诸如马或牛精子细胞的物品。 这种改进的喷嘴系统包括具有新颖的内表面几何形状的喷嘴(16),其可以轻轻地加速细胞并且可以在(c)喷嘴内包括椭圆形的单个扭转内表面元件,即,单个扭转定向喷嘴 (6)。 椭圆形单个扭转内表面元件(例如)(8,9,10)可以具有层流表面并且可以产生最简单的流动路径,用于施加以加速性质或取向的流体动力作用的最小力,即 单一的扭转取向力将诸如动物精子细胞的平坦样品(16)定向到适当的方向,用于临床使用中的分析和有效分选过程,用于研究和动物授精行业。
