CA 2406994

Needle-bearing medical devices (10, 100, 200, 300, 400) are provided for fluid infusion, fluid transfusion, and inserting a guide wire. After use the needle (65, 165, 265, 365) is shielded to render the contaminated needle safe to prevent inadvertent needle sticks. The device includes a housing (20, 120, 220, 320, 420) and a needle having a sharpened tip. A biasing element (60, 160, 260, 360, 460) biases the needle (65, 165, 26, 365, 465) toward a position in which the sharpened tip is shielded.

La présente invention concerne des dispositifs médicaux (10, 100, 200, 300, 400) à aiguilles utilisés dans des perfusions de liquides, des transfusions de liquides, et pour introduire un fil-guide. Après utilisation, l'aiguille (65, 165, 265, 365) est protégée contre tout contact par inadvertance avec des aiguilles contaminées. Ce dispositif comprend un logement (20, 120, 220, 320, 420) et une aiguille à pointe affûtée. Un élément de contrainte (60, 160, 260, 360, 460) pousse l'aiguille (65, 165, 26, 365, 465) vers une position dans laquelle la pointe affûtée est protégée.
