Title (EN) A DISPOSABLE MICROTITER STICK
(FR) TIGE DE MICROTITRAGE JETABLE
Abstract:
(EN) A disposable microtiter stick used in performing chemical immunuoassay tests to determine allergies and ailments of humans and animals that comprises an elongated one-piece flat bottomed polystyrene stick (25) having a series of shallow lense-bottomed wells (26) and a handle extension (28) projected from one end thereby by which the stick can be grasped and lifted. The wells (26) are made shallows so they can be emptied simultaneously on taking the handle (28) and with but a flip of the stick (25) by snap of the wrist instantly ridded of their entire contents. A raised boundary border (31) extends about the top face of the stick (25) surrounding all of the wells (26) so that all wells (26) are filled all at one time with reagent or specimen by simply flooding the bordered top surface area of the stick (25). All of the surfaces of the stick (25) including the well wall surfaces, except for their optically transparent bottom lense (26') viewing areas, are frosted. The bottom surface of the stick (25) is flat so the stick (25) can be rested upon a flat supporting surface but is recessed beneath the lense view areas (26') so as to be kept from being scratched.
(FR) Une tige de microtitrage jetable utilisée pour effectuer des tests d'immunoanalyse chimique dans le but de déterminer des allergies et des maladies chez les êtres humains et les animaux consiste en une tige de polystyrène allongée en une pièce à fond plat (25) ayant une série d'alvéoles ou puits peu profonds (26) avec fonds en forme de lentilles et une extension formant poignée (28) s'étendant à partir d'une extrémité de la tige de manière à pouvoir saisir et soulever cette dernière. Les puits (26) sont peu profonds de manière à pouvoir les vider simultanément en prenant la tige par la poignée (28) et à vider tout le contenu des puits de la tige (25) par un petit coup sec du poignet. Un bord frontière surélevé (31) s'étend autour de la surface supérieure de la tige (25) entourant tous les puits (26) de sorte qu'ils se remplissent tous simultanément avec le réactif ou spécimen simplement en inondant la zone de la surface supérieure bordée de la tige (25). Toutes les surfaces de la tige (25) comprenant les surfaces des parois des puits, à l'exception des zones de vision de lentilles (26') à fonds optiquement transparents, sont dépolies. La surface du fond de la tige (25) est plate de sorte que la tige (25) peut reposer sur une surface de support plate mais elle est évidée sous les zones de vision de lentilles (26') de manière à la protéger contre les égratignures.
