Wearable ventilator system with the use of ASPINA's 4-piston compressor

A startup company had the basis for an idea to develop a wearable ventilator system that offered an opportunity to serve several patient categories.

The challenge was to develop enough air pressure and flow in a relatively small package to make it portable.

During the concept stage, the company was looking for a compressor to be small in size and without an uncomfortable vibration noise. At the time, there were one-piston and two-piston compressors in the market but they did not meet the noise qualifications for the company. That was when ASPINA introduced the new 4-piston compressor.

Working closely with the client, several modifications were made to improve the thermal and electrical efficiency of the entire system. ASPINA provided advanced engineering services that included CAD modeling, extensive life testing, and system cooling modeling.

Life testing was also provided throughout the entire development process and continues today. Improvement of the life of the product will add real value to the client and the ultimate users of the device. The product was then submitted and approved for sale by the FDA and approved for Medicare reimbursement.

In the end, this startup company was purchased by a $3 billion-dollar medical company. There are now thousands of devices in the field providing improved quality of life for patients. Sales of the device are projected to triple over the next few years.

Life testing continues in order to further improve the device. A new version is in the initial stages of design using a new smaller ASPINA developed compressor, which will be lighter and more portable.
