Drug delivery device for buccal and aural applications and other areas of the body difficult to access

摘要

Drug delivery device of the present invention comprises a delivery tube, the delivery tube has the one or more nozzles of the distal end of the pressure chamber, and a transfer tube in the pressure chamber communicates with the fluid. Drug supply source (source of drug) is in the vicinity of one or more nozzles and the handle is located at the leading end of the transfer tube. An energy source is arranged on the handle to provide a pushing pressure of about 2,000psi or less in the transfer tube in order to push the drug from the delivery tube through one or more nozzles. The delivery apparatus is particularly useful for delivering a drug under the fine jet propulsion (microjet propulsion) in the mouth, ears, and other hard-to-reach areas of the body. ; Drugs, tubes, transfer, micro-injection, needle, cylindrical ring, charge,
