Irrigation system and methods of use

A treatment delivery system for treating an infected treatment site of a patient, said system comprising:

• a fluid delivery system for directing a first fluid from a first fluid source to the infected treatment site and for directing a second fluid from a second fluid source to the infected treatment site, wherein the first fluid contains a first therapeutic agent and the second fluid contains a second therapeutic agent, wherein the first therapeutic agent is different from the second therapeutic agent;
• and
• a control unit programmed to control the fluid delivery system according to a treatment process comprising a plurality of phases, wherein
• a first phase of the treatment process comprises a controlled delivery of the first fluid to the infected treatment site, maintaining the first fluid at the infected treatment site for a first period of time, and removing a first site fluid from the infected treatment site, said first site fluid comprising at least some of the first fluid,
• a second phase of the treatment process comprises a controlled delivery of the second fluid to the infected treatment site, maintaining the second fluid at the infected treatment site for a second period of time, and removing a second site fluid from the infected treatment site, said second site fluid comprising at least some of the second fluid,
• a third phase of the treatment process comprises repeating the second phase of the treatment process with the second fluid at least once, and
• a fourth phase of the treatment process comprises repeating the first phase of the treatment process with the first fluid at least once,
• wherein the treatment process of the control unit automatically activates a first transition from the first phase to the second phase, a second transition from the second phase to the third phase, and a third transition from the third phase to the fourth phase, and wherein, after an initial user activation of the treatment process before the first phase, each of said first, second, third, and fourth phases and the first, second, and third transitions are caused to proceed without further user intervention or input,
• wherein the first fluid comprises tobramycin antibiotic fluid and the second fluid comprises vancomycin antibiotic fluid.
