Colposcopy Digital Imaging System

A colposcope digital imaging system is used to perform a colposcopy, a medical diagnostic procedure to examine the cervix. With new technological advancement, the medical device now uses algorithms and different shades of color to highlight areas of interest to a clinician. The color rendition of the touch screen monitor needs to remain consistent through the life cycle of the product, as different shades indicate highlighted areas that may need further investigation. The system requires a full HD (1920 x 1080) display in a small, slim, and light form factor, with a high level of brightness, factoring in the treatment room's high ambient light. A 15.6” 500 cd/m² panel meets these parameters.

The unit is sealed correctly for the environment (IP54 to the front and IPX2 to the rear) to ensure it can be cleaned and disinfected with liquids and astringents, including 99 % isopropyl alcohol and Ethanol, to prevent the ingress of liquid which might damage the internal electronics. Canvys designed and tooled a unique plastic chassis with a sealed front bezel and no external rear vents to prevent ingress. In standard plastic case units, vents aid cooling, so our design team uses heat management electronics to meet these challenges.

The touch sensor can operate without gloves or with two layers of gloves. The touch sensor is thick to make it more robust. The addition of specialized coatings enhance the contrast of the image and limit external light reflection. Canvys’ engineering team designed-in long-life components to ensure a long product life cycle, and reduce the need for costly redesign and recertification.

Due to the strict regulatory controls in this environment, it was necessary to meet the EMI & EMC standard as required by the fourth edition IEC 60601-1-2 and meet other EU standards. As an ISO13485 approved medical device manufacturer, Canvys is certified to manufacture monitors to meet these and UL standards.
