Claim 2
Independent Claim
87 words
An apparatus for preparing skin in advance by forming a plurality of cicatrices thereon to administer insulin to a patient, said apparatus comprising: a housing; a rotatable skin needle assembly having a plurality of skin needles thereon, said assembly being located at one end of said housing and being moved upward and downward; a power supply; means powered by said power supply for vibrating said assembly upwardly and downwardly relative to said housing; and means powered by said power supply for rotating said assembly by predetermined rotations.
Claim 3
Dependent Claim
89 words
An apparatus as claimed in claim 1, wherein said means for vibrating said assembly comprises: an inner yoke and an outer yoke; a magnet provided between said yokes to generate magnetic force through a gap forming magnetic paths between said yokes; a coil guide winding a coil therearound; a shaft rod connected to said coil guide and said assembly, respectively; and a shaft rod guide for guiding said shaft rod; wherein said means for vibrating said assembly is operated by means of interaction of said coil and said magnet.
Claim 4
Dependent Claim
27 words

Claim 5
Dependent Claim
41 words
An apparatus as claimed in claim 2, wherein first coil spring is provided between said inner yoke and said coil guide, and second coil spring is provided between said coil guide and said shaft rod guide to elastically move said assembly.
Claim 6
Dependent Claim
40 words
An apparatus as claimed in claim 1, wherein said means for rotating said assembly comprises a low speed motor, and means for coupling a shaft of said motor to a yoke shaft to which an outer yoke is rotatably mounted.
Claim 7
Dependent Claim
30 words
An apparatus as claimed in claim 5, wherein said means for rotating said assembly further comprises a bearing to exactly transmit rotating force of said motor to the outer yoke.
