A transdermal delivery devices including a roller 9, at least one microneedle 2 supported by roller 9, and at least one reservoir 6 for a suspended matter Wherein the movement of roller 9 on the skin of a patient is so that it rotates and brings that microneedle 2 enters and the skin of patient and entering is contacted with the fluid communication of reservoir 6. Additionally provide a kind of method for assembling a transdermal delivery devices comprising connection microneedle 2 to equipment simultaneously connects reservoir 6 to equipment. It additionally provides a kind of for using a transdermal delivery devices management to the method for the suspended matter of a patient. Microneedle 2 can have the hole circulated with 3 phase of a fluid conduit with Single port 4. When roller moves through skin, catheter port 4 can be entrained into the case that the Single port 5 being bonded in drug reservoir fluidly connects reservoir to microneedle.
