Combatting Seroma

It has been shown in literature that

  • Continuous suction effectively removes fluid from the wound site. *

  • With fluid removal, infectious materials and harmful pro-inflammatory mediators found in seromas are less likely to remain in the region.(5)

*data on file

SOMAVAC® 100 is the only suction device available in the US indicated for seroma and hematoma prophylaxis.

  • SOMAVAC® 100 Sustained Vacuum Device has three mechanisms to prevent back flow into the wound.

  • With one touch disposable fluid collection unit, patients are much less likely to open the distal end of the drains to the environment.
