Sakamoto Decubitus Ulcer Development Model Series

The features and cautions of this model

This Decubitus model was created with the hope that it will become a tool in understanding the eruption of Decubitus and the mechanism of its deterioration, so that one can choose the proper local treatment. When we do treatment on Decubitus, we can only see the surface. But what is the condition of the skin, hypodermal organ, muscles, and bones? We have made it possible to analyze the disease in its various stages from a sectional view, not only from observing the surface. By studying the conditions of Decubitus through this model, one can intuitively understand what is happening underneath the surface which should enable a more smooth choice of effective treatment.

The sectional view of each grade (I-IV) provides for visulalisation of the progressive pathophysiology.

Stage I
The epiderm has not yet been torn, but hypodermic bleeding and other red spots that do not disappear over a length of time are observed.

 Stage II
Abrasion, bubbles, bleeding, and effusion are observed.

Stage III
Healing process of stage IV where the fascia and deeper had been affected.

Stage IV
There is a hole widely separating the fascia and periosteum from the hypodermal organ.
