摘要

"Plastic needle eccentric three strands for veterinary use and other".Especially a needle for preferential use in the veterinary sector, particularly in the operations of extraction of blood and liquids in general, whose particularity is constructive if back,When compared to other needles trifacetadas, design eccentric, generating a series of extraordinary advantages related to the best passage of liquid, the shortest time of extraction.Higher strength, greater lightness and smaller amount of materials necessary for its manufacture.The plastic needle (1) established between the internal diameter (6) and the outer diameter (7), a ratio of eccentricity, which allows for an external diameter (7) better.The same internal diameter (6); the eccentricity causes the wall (8) is established in the region where the tip (9) of the needle (1),While the diametric opposite wall records the smallest value of wall, which is reduced gradually to a diametral point to another, depending on the configuration of an eccentric.
