Abstract:
1. A device for delivering a medicament into a body of a patient by injection into or through a skin surface of said patient, comprising: a housing having a bottom surface adapted to contact a skin surface of a patient; an injection needle adapted for penetration of said skin surface and for movement through a needle aperture; a reservoir, disposed within said housing, said reservoir in fluid communication with said injection needle; and a safety member adapted for movement away from said bottom surface of said housing, said safety member having a covering portion disposed about said needle aperture, and at least one shield protruding from said covering portion, said safety member having a first position wherein said shield of said safety member is initially disposed within said housing and said covering portion is substantially co-planar with said bottom surface of said housing, and a second position wherein said shield of said safety member is at least partially withdrawn from said housing and at least partially covers said injection needle; a spring element configured to bias said shield and covering portion of said safety member toward said second position; and a rotatable door adapted to contact a skin surface of a patient and disposed upon said bottom surface of said housing and having a first position, which prevents movement of said safety member, and a second position, which allows movement of said safety member; wherein when said device is placed upon said skin surface of said patient and activated, said rotatable door is released and free to rotate from said first position to said second position and said spring element is free to urge said safety member into said second position, whereby, as said device is removed from said skin surface, said shield of said safety member emerges from said housing and at least partially covers said injection needle.
