Medical Infusion Pump Membrane Switch Design & Compliance
Medical Infusion Pump Membrane Switch Design & Compliance Medical infusion pumps are critical devices for precise drug delivery, and their membrane switches serve as the primary human-machine interface (HMI) for clinicians to set parameters (e.g., flow rate, volume), start/stop infusion, and access alarms. The design of these switches must balance functional reliability , user safety , and strict compliance with global medical device regulations. Below is a detailed breakdown of key design considerations and compliance requirements. Part 1: Core Design Considerations for Membrane Switches The design of membrane switches for infusion pumps must prioritize durability , tactile feedback , environmental resistance , and compatibility with the pump’s clinical use case . Key design elements include: 1. Material Selection Materials directly impact the switch’s lifespan, sterility, and resistance to harsh clinical environments. Critical materials and the...
