SENSOR FOR MEASURING BLADDER VOLUME, AND SYSTEM AND METHOD OF MANAGING BLADDER USING THE SAME
First Claim
1. A sensor for measuring bladder volume, the sensor comprising:
- an antenna that receives an electric wave;
a transducer that generates a predetermined wave and measures the bladder volume indicating the size of the bladder using the predetermined wave; and
an RFID chip that generates and supplies power using the electric wave received by the antenna, generates information on the bladder volume from the measured bladder volume, and transmits the generated information to the outside through the antenna,wherein the sensor for measuring bladder volume is attached to the skin in an abdominal region of a user.

Abstract
The invention relates to a sensor for measuring bladder volume that includes an RFID chip (particularly, a passive RFID chip) to generate driving power using an electric wave generated by a reader, and to transmit information on the measured bladder volume to the reader using an elastic wave or an electromagnetic wave, and to a system and method of managing a bladder using the same.
A sensor for measuring bladder volume according to an embodiment of the invention includes an antenna that receives an electric wave, a transducer generates a predetermined wave and measures the bladder volume indicating the size of a bladder using the predetermined wave, and an RFID chip that generates and supplies power using the electric wave received by the antenna, generates information on the bladder volume from the measured bladder volume, and transmits the generated information to the outside through the antenna. The sensor for measuring bladder volume is attached to the skin in an abdominal region of a user.
According to the embodiment of the invention, since the sensor for measuring bladder volume does not use a battery, it is reduced in size, thereby improving mobility. Therefore, an adverse affect when the sensor is inserted into the body through a surgical operation can be prevented.
