Infusion Pump Background

Infusion Pumps are used to control medicine and fluids delivered to patients. An Infusion pump usually includes a fluid reservoir, an electro mechanical assemble for controlling fluid flow and catheter system for transferring fluids to the patient. Accurate flow control is critical. PSoC interfaces with sensors in the infusions pump to monitor parameters like pressure or force (fluid flow), temperature, air in-line and provide outputs to control fluid metering through a valve or motor and to identify an alarm condition. PSoC product solutions can also provide direct LCD drive and control, key pad or touch screen interface, power management and USB or RS-232 communication.

PSoC programmable analog & digital resources integrate everything shown in light blue below. Click on the colored blocks to view or sample the recommended PSoC Components.

 

The flexibility of PSoC allows you to customize each colored block, or PSoC Component, to meet your design requirements through the easy-to-use PSoC Creator Software IDE.  These Components are available as pre-built, pre-characterized IP elements in PSoC Creator.


Design Considerations
PSoC® 3 and PSoC 5 provide a scalable platform which integrates all the required circuitry to provide a configurable Infusion Pump in a single chip, including:

 • High precision Analog front end, including a 0.1% accurate Voltage reference and up to 20 bits of resolution
 • Circuitry for controlling the Relay Valve for controlling the flow rate and flow uniformity
 • LCD direct drive and control
 • Power management capabilities including Battery Charging and Protection, Fuel Gauge, and Voltage Sequencing / Monitoring.
 • CapSense fully integrated for buttons
 • Communications including FS USB and RS-232
 • On chip EEPROM


Application Notes

AN52927 - PSoC® 3 and PSoC 5LP - Segment LCD Direct Drive
Although segment LCD modules are available with inbuilt drivers, these modules are more expensive than segment LCD glass. PSoC® 3 and PSoC 5 LP, with its configurable analog and digital hardware, also has an integrated configurable LCD driver that supports a wide variety of LCD glass types. This application note explains how to drive multiplexed segment LCD glass using PSoC 3 and PSoC 5LP.

AN57821 - PSoC® 3, PSoC 4, and PSoC 5LP Mixed Signal Circuit Board Layout Considerations
AN57821 introduces basic PCB layout practices to achieve 12- to 20-bit performance for the PSoC® 3, PSoC 4, and PSoC 5LP family of devices. The design practices covered in this application note are good rules to use in any mixed signal design for any accuracy.
