Abstract:
1. An infusion pump for infusing fluid from a reservoir into a body of a user, the infusion pump comprising: a housing; a drive mechanism including a motor and one or more drive components contained within the housing and operatively coupled to the reservoir to deliver fluid from the reservoir through a fluid path into the body of the user; one or more electronic components to take a series of measurements of a parameter associated with the motor or one of the drive train components; and a controller contained within the housing, wherein, after each measurement in the series of measurements is taken, the controller performs a comparison between the measurement taken and a predetermined threshold value before the next measurement in the series of measurements is taken, and wherein, if the comparison indicates that the measurement taken is less than the predetermined threshold value, the controller determines that there is no occlusion, and said fluid is delivered to the user's body.
