Designed for teaching and training with vacuum assisted closure and negative pressure wound therapy devices, this model. features a large sacral Stage IV pressure ulcer* (NPUAP 2007 Pressure Ulcer Staging Guidelines), with eschar, subcutaneous fat, undermining, tunneling, slough, eschar and exposed bone (with osteomyelitis) and a Stage III pressure ulcer with subcutaneous fat and granulation tissue. The large size and depth of the Stage IV pressure ulcer, as well as the undermining and tunneling, make it ideal for practicing the proper dressing and preparation of a large wound for use with a negative pressure wound therapy device. The Stage III pressure ulcer is positioned so that the Stage IV can be dressed by itself or a “bridging” dressing can be applied to the Stage IV and Stage III to demonstrate and practice this skill. The skills that healthcare professionals learn with this model can be used to obtain positive outcomes with a variety of chronic and acute wound types, such as other pressure ulcers, diabetic wounds, abdominal wounds, trauma wounds, flaps and grafts. Compact and weighting only 2 lbs., this model is easily transportable. This model is made of a unique, flexible material that permits the application and removal of dressings without leaving an adhesive residue. A great tool for training, competency testing, skills assessment, dressing techniques and use of negative pressure wound therapy devices! Size: 9” X 9” X 5”, Wt. 3.0 lbs.
