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
A winged needle as defined in claim 1 including engaging means which engages said base and said wings when said wings are not folded towards said needle.
Claim 6
Dependent Claim 37 words
A winged needle according to claim 1, wherein all of said base, said pair of flat wings, said hinge means, said sheath-portions and said coupling means are formed from a flexible elastic material as a unitary member.
