Title:
インスリンを送達するための方法および装置
Document Type and Number:
Japanese Patent JP7066003
Kind Code:
B2
Abstract:
An inventive drive system for an insulin pump includes a motor configured to rotate at a predetermined revolution speed. It also includes a gear box configured for acting on a piston of the insulin pump to thereby convert a rotation of the motor into a continuous linear motion of the piston via a threaded rod mechanically coupled to the piston. The continuous linear motion of the piston determines a basal rate of insulin delivery. Additionally, a mechanical displacer is provided to act on the piston by adding a mechanical displacement of the threaded rod to the continuous linear motion of the piston, such as during a time then a bolus of insulin is to be delivered in addition to the basal rate. The threaded rod is mechanically coupled to the piston independent of the basal rate. An insulin pump and a method for driving an insulin pump are also disclosed.
