Hospital beds are some of the most used, and overused, pieces of equipment in any major health care facility. It’s no surprise that patients would rather feel comfortable when going under the knife.

Where that comfort isn’t available, medical facilities experience greater incidents of patient injury, leading to longer recovery times and even a decrease in practitioner efficiency.

Hoping to solve this problem and optimize patient comfort, a client in the medical device industry came to DornerWorks. They wanted help developing a hospital bed solution using software that met strict medical standards and simplified testing, all within a tight deadline.

The Pneumatic Hospital Bed Controller DornerWorks built for the client adjusts the air pressure in an inflatable mattress based on the characteristics of the patient using the device.

We provided circuit board layout services for the hardware design from prototype through production, in addition to hardware design consulting. Due to our involvement during early development, we were able to provide insightful feedback into the product design for the client. That feedback helped the client shape the product design to best fit their needs.

DornerWorks software services included providing automated unit test and integration test scripts that fed directly into the client’s quality assurance processes and enabled the client to test their product quickly and efficiently.

Project highlights:

  • Pneumatics Control
  • Pressure Sensing
  • Safety Critical Embedded C on Freescale Coldfire V1 & Freescale S08P MCUs
  • SPI & CAN Inter-processor Communication
  • Participated in Full Product Development Life-cycle
  • Automated software testing

By designing, developing, and testing the embedded software for the pneumatic control and sensing hardware of a controller for an air-filled hospital mattress, DornerWorks helped this client improve their product’s capacity to provide comfort and care for patients.

A product that delivers individualized comfort to each patient that uses it is of extreme value to healthcare systems, as they are providers of one of the most intimate “user experiences.” The embedded solution we helped this medical device manufacturer develop not only met that use case, but was launched ahead of schedule, filling a crucial need in the rapidly moving medical market.
