1.	Which of the following is a characteristic of battery powered pumps?(a) Free flowing powders(b) The system is programmed to release drugs at a controlled rate(c) Control drug release by partitioning the drug from the oil(d) Administration of emulsionsThe question was posed to me in an interview for job.This intriguing question originated from Biopharmaceuticals topic in division Biopharmaceuticals of Drug Biotechnology
Answer» Correct answer is (b) The system is programmed to release drugs at a controlled rate The best explanation: BATTERY powered PUMPS are such that they are programmed to release drugs of a certain AMOUNT when the RANGE of those components is differing from the normal value. Their design is such that the drug moves towards the exit and there is no BACKFLOW of the liquid. They are of two types these are peristaltic pump and solenoid driven reciprocating pump.
