K242111 Page 2 of 4

VIVACE includes the following features:

LCD display shows the current status such as Mode (single, synchronous, alternative, massage, expression), cycle level and vacuum level of both breasts and mood light.
Expression can be performed on one breast only (single mode), on both sides simultaneously (synchronous), or on both sides alternately (alternative).
Expression mode: 1-12 level (50-280 mmHg), cycle speeds (28, 31, 34, 37, 40) י
-Massage mode: 1-6 level (60-160 mmHg), cycle speeds (40, 50, 60, 70, 80)

The breast pump expresses breast milk by creating a seal around the nipple using a flange and applying and releasing suction to the nipple. The milk is collection container, which can be used for storage. To prevent milk from flowing into the vacuum system, a backflow protection membrane (diaphragm) physically separates the milk-contacting pathway from the vacuum system.
