Abstract
A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.
Claims38
A system for treating a tissue site, comprising:
- a fluid source;
- and
- an ultrasonic bubble generator coupled to the fluid source, the ultrasonic bubble generator comprising:
- a gas bubble generator configured to inject micro-bubbles in a fluid from the fluid source prior to the fluid entering the tissue site, and
- an acoustic transducer configured to transmit ultrasonic waves to the micro-bubbles in the fluid prior to the fluid entering the tissue site.
A system for treating a tissue site, comprising:
- a fluid source configured to provide fluid to the tissue site;
- and
- a negative-pressure source fluidly coupled to the fluid source, the negative-pressure source comprising an ultrasonic bubble generator configured to inject microbubbles into the fluid and deform the microbubbles with ultrasonic waves prior to the fluid entering the tissue site.
A system for treating a tissue site, comprising:
- a fluid source configured to provide fluid to the tissue site;
- and
- an ultrasonic bubble generator coupled to the fluid source, the ultrasonic bubble generator configured to inject microbubbles into fluid from the fluid source and deform the microbubbles with acoustic energy prior to the fluid entering the tissue site.
