Abstract
Abstract A winged needle with which the needle can be safely exposed and covered. The winged needle comprises a base into which the needle is rooted, wings which can be folded to cover the needle, sheath-portion of the wings which surrounds the needle on all sides when the wings are folded, and a coupling device which couples the wings. This structure enables a user to handle the winged needle from the base side without having his hand face the needle tip, significantly reducing the possibility of puncturing the user's hands.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A winged needle comprising: a needle; a base into which the needle is rooted; a pair of flat wings which flank both sides of said base, for providing flat surfaces with which said winged needle can be fastened to an arm of a patient; hinge means which allow said pair of wings to fold toward said needle; sheath-portions respectively integrated with said pair of flat wings which surround said needle on all sides when said pair of flat wings are folded toward said needle; and coupling means for coupling said pair of flat wings together with said sheath-portions when said pair of wings are folded to maintain said needle surrounded by said sheath portions.
Claim 2
Dependent Claim
114 words
A winged needle comprising: a needle; a base into which the needle is rooted; a pair of flat wings which flank both sides of said base, for providing flat surfaces with which said winged needle can be fastened to an arm of a patient; hinge means which allow said pair of wings to fold toward said needle; sheath-portions respectively integrated with said pair of flat wings which surround said needle on all sides when said pair of flat wings are folded toward said needle; and coupling means for coupling said pair of flat wings together with said sheath-portions when said pair of wings are folded to maintain said needle surrounded by said sheath portions.
Claim 3
Dependent Claim
53 words
A winged needle as defined in claim 1 wherein said sheath- portions includes: a ditched projection which is formed on one of two meeting edges of the wings and makes a three-sided cover for the needle; and a lipped section which is formed on the other meeting edge and accepts said ditched projection.
Claim 4
Dependent Claim
22 words
A winged needle as defined in claim 1 wherein said coupling means includes female and male parts which couple by elastic deformation.
Claim 5
Dependent Claim
27 words
