ABSTRACT:
This invention relates to a pressure measurement apparatus for inspecting therapentic energy waves, e.g. shock waves or ultrasonic waves. The pressure measurement apparatus for inspecting focal position and pressure of therapeutic energy waves comprises a pressure sensing sheet which changes visually or electrically according to the pressure, and a marker for setting the focal position, mounted on the pressure sensing sheet. Also, the apparatus for inspecting focal position and pressure of therapeutic energy waves in a water tank, comprises, a pressure sensing sheet which changes visually or electrically according to the pressure, a mount for holding the pressure sensing sheet as a flat shape, a mount holder for holding the mount, a marker for setting the focal position, held above the pressure sensing sheet from the mount holder, and holder means for holding the mount holder into the water tank. It is an object of the present invention to provide a pressure measurement apparatus for inspecting therapeutic energy waves, e.g. shock waves and ultrasonic waves wherein the pressure of the energy waves is measured easily. It is another object of the present invention to provide a pressure measurement apparatus for inspecting therapeutic energy waves, wherein it is easy for the user to judge the focal position.
