Abstract
A set of double needles of injecting liquid medicine comprises an inner needle and an outer needle into which the inner needle is inserted. The inner needle is longer than the outer needle and has a curved portion at the top thereof, so that the curved portion of the inner needle protrudes from the outer needle when the inner needle is fully inserted into the outer needle. On the other hand, the curved portion of the inner needle is straightened in the outer needle when the inner needle is retracted in the outer needle so that the inner needle can be rotated therein whereby the injecting point can be varied in a predetermined area in a single puncturing of the needles.
