Nebulizer Circuit Board

  SPECIFICATIONS

Medical nebulizers are drug delivery devices that break up medications into small aerosol droplets and deliver them directly to the airways for respiratory therapy. Medical nebulizers are commonly used for the treatment of COPD, asthma, cystic fibrosis and other respiratory diseases.

Vibrating mesh nebulizers, such as demonstrated by Microchip's Vibrating Mesh Nebulizer Demo have many advantages such as small size and portability, quiet operation, short treatment times, battery operation, increased output efficiency and minimal residual volume.

Microchip’s Vibrating Mesh Nebulizer Demonstration Board shows a unique implementation for cost-effective drug delivery devices. The integrated Core Independent Peripherals (CIPs) on Microchip's PIC16F1713 8-bit MCU significantly offload the MCU's core in handling the control functions of a piezoelectric transducer mesh nebulizer. These functions include driving the boost and piezo output stages.

Microchip's MCUs with CIP are designed to handle tasks independently with no code or supervision from the MCU's core during operation. Using CIP can shorten the development time of complex control systems, reduce the design's component count, board size and power consumption, as well as give you the flexibility to innovate.

 FEATURES

● Single-chip implementation of a piezoelectric vibrating mesh nebulizer

● Cost-effective method for drug delivery devices

● Boost and Piezo output stages use only discrete components

● Core Independent Peripherals (CIP) handle the following functions of this demo:

● The CLC, PWMs, op amps, comparators and DACs drive the first boost stage

● The NCO drives the piezo output stage

● CIPs significantly offload the MCU’s core, thereby freeing it up for other tasks

● Powered by three AAA batteries, USB or external power supply
