The SOMAVAC 100 post-surgical pump (SOMAVAC Medical Solutions) is the first innovation in hand pumps in decades, according to the company.
The current standard treatment for extracting fluid from closed wounds and reducing the risk of seroma is to use closed-loop aspiration systems that aspirate the fluid with manual aspiration. A flexible suction bulb attached to the end of the drain generates the suction.
SOMAVAC 100 is approved by the FDA and indicated for use in surgeries which lead to large surgical flaps requiring drains, such as abdominal surgery, mastectomy and related cosmetic surgeries. The device applies continuous suction to closed postoperative wounds, which the researchers believe is important for effectively removing fluids, bringing the planes closer to the tissue, and possibly promoting healing. Nowadays, manual suction bulbs lose pressure, which prevents many of them from providing adequate continuous suction.
SOMAVAC 100 eliminates the need to empty and recharge the bulb. Instead, users replace filled collection bags and replace batteries as needed, which helps reduce odors.
“… The drain and the pump can be worn discreetly under clothing, which helps patients to resume their normal activities while recovering”, according to press information published on SOMAVAC 100.
Jeffrey E. Janis, MD, professor of plastic surgery, neurosurgery, neurology and surgery at the Wexner Medical Center at Ohio State University in Columbus, says advances in drainage technology and what he calls “drainage hygiene” are long overdue.
Dr. Janis and her colleagues wrote “Optimal use of surgical drains: evidence-based strategies”, published in June 2018 in Plastic and reconstructive surgery to help define the parameters that affect the efficiency of the drain in the use of a standard drain.
One of the problems with standard drains is that doctors and patients don’t always follow the evidence on the best way to use manual drains, says Dr. Janis. He and his co-authors carried out an exhaustive documentary analysis and an in vitro analysis of the variables affecting the drain function.
Among their discoveries: “The bulbs generate more effective suction when they are pressed” side by side “than if they are tight (” bottom-up “), and the evacuators are only capable of generating the half of the maximum negative pressure when they are 25% or more full. The stripping of the drainage tubing relieved the clogging caused by coagulation. ”
SOMAVAC 100 technology automates many of the potential barriers to proper use, according to Dr. Janis, who is familiar with SOMAVAC 100 but uses standard drains at Ohio State University.
“This new technology automates some of these features, which greatly reduces the maintenance of doctors and patients, which is always a good thing,” he said. “At the end of the day, I don’t know anyone who really likes drains. But if you want to use them because you need them, I think it’s nice to see that progress has been made in this space to make things technologically advanced and easier to use. ”
Dr. Janis, who has no conflict of interest in this area, states that the State of Ohio could use SOMAVAC 100 in the long term, but that it currently uses a standard technology that applies best evidence practices.
