Evaluation of a novel portable micro-pump and infusion system for drug delivery

摘要

In this paper the design, fabrication and experimental results of a novel portable fixed-displacement micro-pump for controlled dosing and timing is described. The new pump is developed especially for high efficiency, high accuracy, ease of use and very low cost for single use drug delivery systems which can overcome many of the deficiencies of current portable pumps. Primary tests have been conducted and the results have demonstrated that the pump has the ability to deliver high performance and accuracy with less than +/-1% error over the whole operating flow rate range of 0.05-120 (mL/h). The pump is designed to be used with a motor drive, which has been configured to be the size of a typical pen, improving the patient's mobility and wellbeing. The new micro-pump can be used for a variety of applications including chemotherapy, insulin delivery, pain management and antibiotic therapy. A complete therapy system is enabled by providing physicians with devices that programme the Pendrive for patient specific therapies.
