Abstract

The present invention relates to a container for a disposable needle or cannula, intended to facilitate needle or cannula placement for the infusion of a liquid drug under a patient'"'"'s skin, the container comprising: a cylindrical housing (1; 101) in which there are defined a cap (1a; 101a) and a sleeve (1b; 101b) provided with a resting base (1c; 101c), said cap (1a; 101a) being axially slidable relative to said sleeve (1b; 101b) when a sufficient pressure is exerted on said cap (1a; 101a); a needle (21; 121) or cannula, which is located inside said housing so as to be directed towards said resting base (1c; 101c) for the infusion of the drug; a retaining member (9; 109), which is located within said housing (1; 101) between said cap (1a; 101a) and said sleeve (1b; 101b) and to which said needle (21; 121) or cannula is secured; said container being equipped with a releasing member for releasing said needle (21; 121) or cannula when said cap (1a; 101a) is made to slide on said sleeve (1b; 101b).

Claims

23. A container for facilitating placement of a cannula of a medical device through a patient'"'"'s skin, the container comprising:

a housing comprising a cap telescopically slidable over a sleeve, said sleeve defining an axis therethrough and including a resting base configured for placement against said patient'"'"'s skin, said cap being slidable between a first position and a second position along the axis of said sleeve, wherein said cap substantially encases the axial length of said sleeve when said cap is in said second position; and

a retaining member located within said housing, said retaining member having a piercing member secured thereto, said piercing member extending at least partially through said cannula for transcutaneous placement of said cannula;

wherein said piercing member is concealed within said sleeve when said cap is in said first position and exposed from said sleeve when said cap is in said second position;

wherein upon exertion of said pressure on said cap, said cap slides axially toward said patient'"'"'s skin along said sleeve so that said piercing member is placed through said patient'"'"'s skin and an end of said cannula is transcutaneously inserted and said medical device is retained on the patient and said piercing member is removed together with said housing.
