Patent

CA 2640114

The invention relates to a device for assaying sperm motility comprising: (a) a sample inlet port (32); (b) a sperm detector comprising: a first sample flow channel (38) extending from the inlet port (32); and a sperm detection region (34) in fluid communication with said flow channel (38); wherein the sperm detection region comprises an acoustic wave sensor, or microfabricated cantilever (50), and a sperm binding surface (44) capable of binding sperm. Methods of assaying for sperm motility are also provided comprising: (i) Providing a sample of sperm at an inlet; and (ii) Determining the rate at which sperm bind to a sperm detector distal to the inlet.

L'invention concerne un dispositif pour analyser la motilité du sperme comprenant : (a) un orifice d'entrée d'échantillon (32) ; (b) un détecteur de sperme comprenant : un premier canal de circulation d'échantillon (38) s'étendant depuis l~orifice d'entrée (32) ; et une région de détection du sperme (34) en communication fluide avec ledit canal de circulation (38) ; la région de détection de sperme comprenant un capteur d'onde acoustique, ou une console microfabriquée (50), et une surface de liaison du sperme (44) susceptible de lier le sperme. L'invention concerne également des procédés d'analyse de la motilité du sperme consistant à : (i) obtenir un échantillon de sperme au niveau d'une entrée ; et (ii) déterminer la vitesse à laquelle le sperme se lie à un détecteur de sperme distal par rapport à l'entrée.
