Abstract: Drug delivery reservoir for delivery of a beneficial agent to a user includes a drug delivery reservoir housing having a fluid reservoir defined therein. The drug delivery reservoir housing has a drug delivery reservoir base region. The drug delivery reservoir includes a dip tube extending inside the fluid reservoir. The dip tube includes a tubular wall defining a flow lumen. The tubular wall has at least one aperture defined therein and spaced proximally from a distal end of the tubular wall in fluid communication with the fluid reservoir. The drug delivery reservoir includes an adaptor disposed external to the drug delivery reservoir housing and coupled to a proximal end of the dip tube.
