I had worked in a research lab on TBI when we used a blast tube to collect data on pressure being applied to the brain. One of the issues that we experienced was the amount of pressure that were actually being applied to the mice, needing a buffer of sorts. The data showed that the intensity of the force was so great that it was difficult to get the data in the controls that were used as set points. They remedied this with kind of an armor that was built for the mice.
