Modeling of non-invasive Xylocaine delivery system for dentistry

Non-invasive method of delivering selected drugs to the target site for certain dental procedures is an emerging area in biomedical engineering and this paper summarizes the authors' research work in designing a portable drug pump for certain dental procedures. The system has been designed taking into consideration the target sites which are situated in the buccal cavity. The system has a disposable pump head, housed in the tip of the applicator containing a drug transport system for transporting the required drug to the applicator head. The discrete drug head contains embedded electrodes which are energized using an inbuilt stimulator of the applicator. This system has the advantage of transporting selected drugs in required doses to the drug holding cell and has the capacity to transport certain hydrophilic and hydrophobic drugs to the target site. The system has been designed mainly to provide local analgesic dose to the target site as a prelude for many dental procedures.
