Abstract
An indwelling needle assembly has a hollow outer needle, an outer-needle hub fixed to the base end of the outer needle, an inner needle inserted into the outer needle, an inner-needle hub fixed to the base end of the inner needle, a tube connected to the base end (or a side section) of the outer-needle hub so that the inner cavity of the tube is communicated with the inner cavity of the outer needle, and a protector that, when the inner needle is removed from the outer needle, covers at least the point of the inner needle and disconnectably connected to the outer-needle hub. A finger hold is formed in a projecting manner on a protector cover of the protector, and the finger hold is pressed by a finger to move the outer needle in the direction of its tip relative to the inner needle. The finger hold is formed in a shape that, when the outer needle is moved in the direction of its tip relative to the inner needle, causes force applied in the direction in which the finger hold projects relative to the center axis of the outer needle to act on the finger hold.
