PORTABLE INFUSION DEVICE WITH REDUCED LEVEL OF OPERATIONAL NOISE

摘要

An infusion system, method and device for infusing therapeutic fluid into the body of a patient are provided. The device includes a driving mechanism including a plurality of gears, wherein at least one gear is adjacent to another gear. The device includes a gear in the plurality of gears having plurality of teeth and at least another gear in the plurality of gears having a plurality of teeth. The plurality of teeth of another gear interact with the plurality of teeth of the gear. At least one tooth in the plurality of teeth of the gear is elastically deformable for causing at least one tooth to elastically deform upon meshing with a tooth in the plurality of teeth of another gear and further for causing reduction of noise associated with operation of the driving mechanism.
