WOUND TREATMENT SYSTEM AND SUCTION REGULATOR FOR USE THEREWITH
First Claim
1. A system for the treatment of wounds by applying a negative pressure to a wound site, the system comprising:
- an electronically controlled suction regulator, said suction regulator comprising;
a vacuum regulator,a coupler for coupling said vacuum regulator to an external vacuum source,a valve connected to said vacuum regulator for supplying a negative pressure to the wound site, anda control circuit for generating control signals for controlling said valve so that negative pressure may be continuously or intermittently supplied to the wound site; and
a wound dressing provided at the wound site and coupled to said electrically operated valve, 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.
