WOUND TREATMENT SYSTEM
First Claim
1. A system for the treatment of wounds by applying a negative pressure to a wound site, the system comprising:
- a suction regulator comprising;
a vacuum regulator for supplying a negative pressure to the wound site, anda control circuit coupled to said vacuum regulator for generating control signals for controlling said vacuum regulator to selectively supply the negative pressure to the wound site;
a wound dressing provided at the wound site and coupled to said vacuum regulator, said wound dressing comprising;
a wound dressing pad for placing over the wound, anda wound drape provided over said wound dressing pad and the wound site for securing said wound dressing pad and sealing the wound site for application of the negative pressure; and
a pressure verification mechanism in communication with the wound site for providing visual verification that the negative pressure applied to the wound site has reached a predetermined pressure level.

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.
