NJPRO vacuum pump applied in Negative Pressure Wound Therapy (NPWT)

A drainage is applied to the acute or chronically moist wound and sealed airtight with an adhesive film. The connected vacuum pump creates a controlled, localized negative pressure and evacuates wound secretion through the drainage. This cleans the wound, improves blood circulation and stimulates the growth of new blood vessels.

As the vacuum devices are often battery-operated and worn directly on the patient, the pumps used must meet high requirements. Only small precision pumps that are as light as possible come into consideration. In order to build up an intermittent negative pressure, the pump must be regulated precisely and reliably, and it must also have minimal power consumption. Due to the close-to-the-body operation, a pump that runs with very little noise and vibration is required at the same time.

Diaphragm pumps are the ideal pumps for NPWT applications. As medical vacuum pumps for wounds, diaphragm pumps offer a wide range of advantages over other pumps. They are safe to use and robust, offer a wide performance range, are relatively small and have a low current draw. These properties make diaphragm pumps the ideal technology for NPWT.
