Abstract: In a non-contact pressure measurement system of a balloon catheter and a non-contact pressure measurement method of the balloon catheter using the same, the system includes a chamber part, a balloon, a tube part, a pump part and a displacement sensor. The chamber part stores a saline solution. The balloon is disposed inside of a body and is configured to be expanded with supply of the saline solution. The tube part is configured to connect the chamber part with the balloon. The pump part is configured to control the supply of the saline solution via the tube part. The displacement sensor is 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.

Abstract: A core body temperature measurement device includes a body and an operation unit. The body is fixed to an ear canal of user. The operation unit is combined with a front side of the body, and is configured to be exposed to the ear canal or to be concealed inside, and has a sensor part. the sensor part measures a core body temperature of user when the operation unit is exposed to the ear canal.
