Medical Products

There are a variety of Medical Applications that utilize the UNISON RTOS with the MedicalOS configuration. These applications range from surgical equipment such as electronic scalpels through wireless stethascopes, smart walkers and entrainment devices.

 

The big issues for Medical Devices are significantly different than those for consumer goods, industrial goods and other manufactured products. Consider the following criteria:

  • ● Mean time before replacement
  • ● Probability of failure in use
  • ● Cost (initial cost and operating cost)
  • ● Operating convenience
  • ● Durability
  • ● Software history
  • ● Privacy
  • ● Authentication and authorization
  • ● Security
  • ● Size, power and weight (SWaP)
  • ● Certification by country

These criteria are relevant to other areas like industrial goods, consumer goods and military systems but depending on the application, the requirements for these different factors differ. Medical products are quite unique. For this reason, the UNISON RTOS has a MedicalOS configuration which specifically deals with medical product development.

Medical systems generally require very high reliability for devices used in life critical applications. For this reason medical devices are certified on a country by country basis. This certification itself is expensive and adds to the overall time and cost of bringing the product to market which means that prices must be higher to cover the fixed R&D costs associated with certification and the interest to cover the delay in getting to market.

Certification efforts can be greatly enhanced through the use of open standards. For this reason, all RoweBots offerings are based on open standards wherever possible. POSIX APIs are proven in many systems and reuse of these standards provides an immediate level of assurance. Testing against these standards for medical systems is vastly simpler and much more reliable. Open standards wherever possible are key to medical product development. UNISON RTOS MedicalOS specifically deals with these issues.

Medical costs are a key concern of all developed countries today. The ability to control costs through more effective and lower cost procedures and devices is critical to being able to bring products to market. If the cost of operating a particular instrument is very high, then it will see more limited use and there will be less willingness to purchase the device even if the results are excellent. Medical organizations are very budget sensitive today. By utilizing UNISON MedicalOS, costs are contained while maintaining the very highest quality and lowest time to market.

Key areas in the medical area are privacy, security, authorization and authentication. Sometimes it is very difficult to resolve what is required in this area. Most of the time, a general application of the key security pieces at our disposal are enough but it is not always the case. These key security components are discussed in detail in other pages; however the short list is:

  • ● TLS for end to end security
  • ● IPSec for VPN setup
  • ● SNMP v3 for secure management
  • ● Secure email
  • ● HTTPS or secure web connections
  • ● Secure boot
  • ● Encrypted file system
  • ● Filtering in all network connections.

RoweBots uses a POSIX RTOS standard in the UNISON RTOS and MedicalOS configuration. Along with this, security components have been integrated in throughout, not simply added as an afterthought. This approach guarantees a high level of security along with superior quality, minimum time to market and lowest total cost of ownership.
