Medical Devices for Home Use Must Achieve Fail-Proof Standards
Improved clinical outcomes are now possible in a growing number of applications where patients are able to safely operate medical devices in their home environments
Unlike medical devices used in clinical settings where trained technical staff is usually on-hand to verify that devices are operating as designed, medical equipment designed for patients’ use in their homes must be more thoroughly tested and proven to be reliable before release to the patient’s home environment.
In practical terms, this means that testing during assembly must be more extensive and more sensitive, without adding significant cost
Multi-Valve, Multi-Port Testing
An example of this trend is dialysis machines designed for patient’s use in their home environments. Achieving fail-safe standards is complicated by the complexity of dialysis equipment. Multiple solenoid valves must be controlled with precision and many dozens of ports must be operable at all times.
