A lancet assembly capable of puncturing with less number of steps and safely treatable after puncturing. The lancet assembly comprises a lancet and a lancet holder storing the lancet holder. The lancet comprises a lancet body, a lancet cap, and a puncturing member. The puncturing member is provided in the lancet body and the lancet cap, and the lancet cap covers the tip part of the puncturing member. The lancet cap and the lancet body are integrally joined to each other through a bridge member. The lancet assembly is characterized in that when the lancet cap is pressed while the lancet body is fixed to the inside of the lancet holder, the bridge member is broken and the lancet cap is separated from the lancet body and when the separated lancet cap is further pressed, it is moved to a position derailed from a puncture route for the puncturing member.

L~invention concerne un ensemble de lancette capable de réaliser une ponction en moins d~étapes et pouvant être retiré en toute sécurité à l~issue de la ponction. L~ensemble de lancette comprend une lancette et un porte-lancette protégeant la lancette. La lancette comprend un corps de lancette, une coiffe de lancette et un élément de ponction. L~élément de ponction est monté dans le corps de lancette et dans la coiffe de lancette. La coiffe de lancette recouvre le bout de l~élément de ponction. La coiffe de lancette et le corps de lancette sont solidarisés par un élément de raccord. L~ensemble de lancette est caractérisé en ce que, lorsque la coiffe de lancette est enfoncée alors que le corps de lancette est fixé à l~intérieur du porte-lancette, l~élément de raccord se casse et la coiffe de lancette se sépare du corps de lancette et, lorsque la coiffe de lancette séparée est enfoncée davantage, elle s~écarte de la trajectoire de ponction de l~élément de ponction.
