Abstract: A system is provided for the treatment of wounds. The system comprises a wound dressing and a suction regulator that includes a vacuum regulator for supplying a negative pressure to the wound site and a control circuit for controlling the vacuum regulator to selectively supply the negative pressure. The system may further comprise (1) a pressure verification mechanism for providing visual verification that the negative pressure applied to the wound site has reached a predetermined pressure level; (2) a venting mechanism for allowing oxygen to vent to the wound site when the negative pressure is not supplied to the wound site; (3) a flow sensor for sensing a flow rate from the wound site where the control circuit generates an alarm signal if the flow rate sensed by the flow sensor exceeds a threshold; and/or (4) a wound dressing pad comprising a support material at least partially covered with silicone.
