Title:
【発明の名称】蠕動ポンプ構造におけるパワー消費の減少
Document Type and Number:
Japanese Patent JP2003518226
Kind Code:
A
Abstract:
The present invention utilizes a torque compensation system and a power control feedback system to reduce power consumption in a linear peristaltic pump. The linear peristaltic infusion pump includes an electric motor, which is connected to a cam shaft with multiple cams positioned thereon. Numerous elongate fingers cooperate with the cams to partly occlude an intravenous drip tube at multiple points along the tube's path. A torque compensation system and power feedback control system reduce the overall power consumption of the pump. A torque compensation cam positioned on the cam shaft, in combination with a torque compensation cam follower and a mechanical spring assist the motor while it is working against a rising cam follower. The power feedback control system comprises a controller which optimally adjusts the power supplied to the drive means so as to reduce overall power consumption of the pump.
