1. A non-contact pressure measurement system comprising:
a chamber part storing a saline solution;
a balloon disposed inside of a body and configured to be expanded with supply of the saline solution;
a tube part configured to connect the chamber part with the balloon;
a pump part configured to control the supply of the saline solution via the tube part; and
a displacement sensor configured to measure an amount of the expansion of the tube part expanded with the supply of the saline solution, in a predetermined section of the tube part;
a database in which a relationship between a pressure applied to the tube part and the expansion of the tube part, for the types of the tube part; and
a pressure measuring part configured to measure the pressure applied to the tube part, based on the information stored in the database and the amount of the expansion of the tube part measured by the displacement sensor.
