Abstract
This note describes the design of a flexible pressure controller used in a multi-chamber portable therapeutic device. The device presents many novel features. There is a complete flexibility in setting the pressure profile for each of the chambers according to the needs of individual patients. The device is programmable via a personal computer and a USB interface. The design is optimised for power use and can be run on a battery for over a thousand cycles. The set pressure profile is tracked using a continuous pressure feedback and a proportional-derivative-integral controller. This paper also includes patient data to show the effectiveness of this multi-chamber device. The tests on the patients were conducted using a prototype built using the design described in this paper.
