This paper proposes a implantable intrathecal drug infusion pump for pain control in terminal cancer patients. This pump consists of micropump module, drug reservoir module and control module. The micropump module using cam-follower mechanism composed of small-sized four cams and four followers. Each followers is driven by a cam and liquid is discharged by a sequential reciprocal motion of the followers. The advantage of this structure is that it allows the pump to be clean and valveless. The drug reservoir module composed of drug chamber, gas chamber and diaphragm. The control module composed of battery, wireless communication unit and controller. To design a small-sized, low power pump some analysis were performed to determine the design parameters. To verify the feasibility of the experiment, a prototype was manufactured and its operating characteristics were investigated. Experimental results were in accordance with the expected results obtained from analysis.

This paper proposes a tube pump which have small-sized cams and followers for an implantable intrathecal drug infusion device. The operation principle of the pwnp is that each of the followers is driven by four cams. Due to its sequence reciprocating motion, liquid is discharged. This structure has the advantage of clean and valveless pump. To design a suitable, low power and a small-sized pump, some analysis are performed to determine the design parameters of the cam, follower and the tube. To verify the feasibility of the experiment, a prototype is manufactured and its operating characteristics are investigated. In addition experimental results show the performance of the proposed pump,

A disk-type 3-DOF actuator which has new principle and very simple structure is proposed. Also it utilizes the relation of bias and control fluxes produced by permanent magnets and coils, respectively, like other conventional electromagnetic actuators, but its main feature is that both the coils and permanent magnets are fixed in the stator, which makes it easy to design the shape of moving part. Operating principle is that a moving disk is driven by reaction force of Lorentz force acting on the fixed equivalent coil. Simple analytic approach and FEM analysis are performed to determine the design parameters so as to increase the driving force and distance. And some experimental results show the feasibility of the proposed actuator.
