Medical Devices
Capacitive touchscreens serve as core interactive components in numerous medical devices, thanks to their features such as precise interaction, easy cleaning, and adaptability to special operation needs. They comprehensively enhance the efficiency and safety of medical services across clinical diagnosis and treatment, as well as patient management.
I. Core Application Scenarios
1. Clinical Diagnosis and Treatment Equipment Ultrasonic diagnostic equipment and endoscope monitors: Equipped with capacitive touchscreens, they support multi-finger zooming and precise annotation. Doctors can quickly zoom in on lesion images, mark key areas, and the high-resolution display helps clearly present fine tissue textures. Patient monitors: Capacitive touchscreens enable real-time access to vital sign data (such as ECG and blood oxygen). They still respond accurately even when medical staff wear thin medical gloves, avoiding operation delays.2. Patient Interaction Terminals -
Mainly include outpatient consultation screens and consultation room terminals, which are used for basic operations such as patient information inquiry and consultation interaction.
3. Special-Scenario Equipment ICU-specific equipment: The capacitive touchscreens are coated with an anti-corrosion layer, which can withstand repeated wiping with iodophor and disinfectant. Surgical navigation equipment: Equipped with anti-glare capacitive touchscreens, they can still display images clearly under strong light in the operating room, assisting in precise operations.II. Key Technical Requirements
1. Interaction Precision Touch precision reaches the 0.1mm level, and the touch recognition rate is ≥99% when wearing 1-3 layers of thin medical gloves.The response latency is ≤50ms, reducing the probability of operational errors.
2. Cleaning and Protection Adopt a seamless screen design with no gaps between physical buttons, and the surface hardness is ≥7H (Mohs hardness). It can withstand frequent wiping with 75% alcohol, chlorine-containing disinfectants, etc., without any attenuation of touch performance after wiping.

3. Environmental Adaptability Operating temperature range: -20℃~60℃; humidity range: 30%~90% (without condensation). Electromagnetic compatibility (EMC) complies with the IEC 60601-1-2 standard, preventing interference from the electromagnetic environment of medical equipment.
Electromagnetic compatibility (EMC) complies with the IEC 60601-1-2 standard, preventing interference from the electromagnetic environment of medical equipment.
4. Durability The touch service life is ≥5 million single-point presses. The surface anti-corrosion coating must pass more than 500 wiping tests with highly corrosive reagents (such as iodophor) to ensure long-term stable operation.
