Medical nebulizers are drug delivery devices that reduce a liquid medication to extremely fine cloud-like particles 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.
Nebulizers tend to be divided into three categories: jet nebulizers, ultrasonic nebulizers and mesh nebulizers. Each type of nebulizer has its own relative strengths. Recently there have been many improvements in mesh nebulizers.
Mesh nebulizers force liquid medications through multiple apertures in a mesh or aperture plate in order to generate aerosol droplets. This type of nebulizer has the advantages of being small and portable, powered by batteries, silent in operation, yield shorter treatment times, give increased output efficiency, and have minimal residual volume. Other advantages include a predominantly fine-particle fraction that reaches into the peripheral lung and the ability to nebulize in low drug volumes.

As medical remote patient monitoring becomes more important, the need for wearable ECG capability has become critical. Microchip’s Connected, Wearable ECG Demonstration Board can be used in the design of advanced fitness tracking devices and can also be designed into medical wearable remote patient monitoring and diagnostic systems.
High-end wearable activity trackers can take step count, temperature, light and other movement and environment measurements. They are not only being used for fitness applications but are becoming an essential part of medical device design. Microchip’s Ultra Low-Power or ULP Connected, Wearable Activity Monitor Demonstration Board can be used as the starting point for the design of medical home monitoring, patient tracking and drug delivery compliance devices.
