Kind Code:
A1
Abstract:
In one embodiment of the present disclosure, provided is a needle assembly formed having the following parts, which are each configured such that at least a portion thereof can be housed in a casing formed having an opening: a needle support part on which is supported a hollow needle through which a medicinal solution can flow; a moveable needle cover part which is able to be moved inside of said opening so as to externally expose the medicinal solution-injecting side tip of the needle at the time of use; a cylinder part which is disposed on the needle support part and in which a portion thereof can come in contact with the moveable needle cover part; and a biasing part configured such that when the moveable needle cover part is moved in one direction, the moveable needle cover part is biased in the opposite direction to the one direction. By moving the moveable needle cover part in the one direction, at least the moveable needle cover part comes in contact with the cylinder part and is axially rotated from a prescribed position prior to being moved, to another position, the axially rotated moveable needle cover part is thereby able to be moved in the opposite direction due to the biasing part, and the axially rotated moveable needle cover part which has moved completely in the opposite direction can be interlocked with the casing.
