Container for disposable needle or cannula
DCFirst Claim
1. A container for facilitating placement of a medical device through a patient'"'"'s skin, the container comprising:
- a cylindrical housing in which there are defined a cap and a sleeve, said sleeve including a resting base having a planar surface configured for placement against a patient'"'"'s skin, said cap surrounding at least a portion of said sleeve and being axially slidable relative to said sleeve to substantially encase said sleeve when a sufficient pressure is exerted on said cap;
a retaining member located within said housing, said retaining member having a needle secured thereto;
a releasing member for releasing said needle from said retaining member when said cap is made to slide on said sleeve, thereby allowing the placement of said needle under the patient'"'"'s skin and the subsequent removal of said container;
wherein the container is disposable and upon exertion of said pressure on said cap the force resulting from said pressure is transferred to said needle so that said needle is placed through the patient'"'"'s skin by means of said pressure exerted on said cap.

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 including 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), the cap (1a; 101a) being axially slidable relative to the sleeve (1b; 101b) when a sufficient pressure is exerted on the cap (1a; 101a); a needle (21; 121) or cannula, which is located inside the housing so as to be directed towards the resting base (1c; 101c) for the infusion of the drug; a retaining member (9; 109), which is located within the housing (1; 101) between said cap (1a; 101a) and the sleeve (1b; 101b) and to which the needle (21; 121) or cannula is secured; the container being equipped with a releasing member for releasing the needle (21; 121) or cannula when the cap (1a; 101a) is made to slide on the sleeve (1b; 101b).

5. A container for facilitating placement of a medical device through a patient'"'"'s skin, the container comprising:
-
a cylindrical housing in which there are defined a cap and a sleeve, said sleeve including a resting base having a planar surface configured for placement against a patient'"'"'s skin, said base having, on an outer face, a gauze adhering to said base, said gauze comprising an adhesive having a removable protecting film thereon, said cap being axially slidable relative to said sleeve when a sufficient pressure is exerted on said cap; a retaining member located within said housing, said retaining member having a needle secured thereto; a releasing member for releasing said needle from said retaining member when said cap is made to slide on said sleeve, thereby allowing the placement of said needle under the patient'"'"'s skin and the subsequent removal of said container; wherein the container is disposable and upon exertion of said pressure on said cap the force resulting from said pressure is transferred to said needle so that said needle is placed through the patient'"'"'s skin by means of said pressure exerted on said cap and wherein said needle is an L-shaped needle comprising a drug inlet branch transversally arranged within said housing and an axially arranged drug outlet branch, said inlet branch being connected to a hose radially extending from said container. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

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 secured to said retaining member is removed. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 32, 33, 34, 35)
