Description

technical field [0001] The invention relates to an optical fiber temperature measuring sensor, in particular to an anti-electromagnetic interference medical in vivo optical fiber temperature measuring sensor, which belongs to the technical field of medical temperature measurement. Background technique [0002] In the medical field, it is often necessary to measure the temperature of the human body. In the process of tumor hyperthermia, thermochemotherapy and magnetic therapy, it is necessary to heat the tumor site by means of external radio frequency electromagnetic field, so that the temperature of the tumor site reaches 42-44 degrees Celsius, so as to kill tumor cells and protect normal human tissues from damage. In order to achieve the purpose of treatment without causing damage to the human body, it is necessary to monitor the temperature of the tumor site in real time in order to accurately control the strength of the electromagnetic field, effectively kill tumor cells,...
