Abstract

A preparation delivery assembly includes: a first substrate, a second substrate, and at least two needles of different lengths. Two side walls are provided between the first and second substrates to define a first chamber. At least one first channel that is in communication with the first chamber is provided in the second substrate in a direction perpendicular to the second substrate. And the needles are arranged on a surface of the second substrate, and each needle is in communication with the first chamber to deliver the preparation. A third channel is provided in the first substrate in a direction perpendicular to the first substrate, and one end of the third channel is in communication with the first chamber so as to guide the preparation introduced from the other end of the third channel into the first chamber.
