Fluorescent fiber optic temperature measurement can be directly applied in thermal therapy temperature measurement, physical therapy temperature measurement, and medical temperature measurement
In many fields that require hyperthermia nowadays, accurate measurement of the patient’s body temperature is particularly important. Currently, existing in vivo hyperthermia instruments have the problem of not being able to accurately measure the body temperature, and temperature errors seriously affect the precise treatment effect of hyperthermia equipment. Therefore, it is urgent to provide a precise and non-destructive temperature measurement method to solve practical problems. At present, temperature measurement methods include thermocouple method, fiber optic method, infrared method, thermal paper method, liquid crystal foil method, model material method, microwave radiation method, nuclear magnetic resonance method. Among them, only fiber optic temperature measurement is suitable for anti electromagnetic interference temperature measurement.
Why does thermal therapy equipment require precise temperature measurement
A hyperthermia device is an instrument that achieves clinical efficacy by heating human tissues. High frequency hyperthermia equipment is a type of hyperthermia equipment. In the oncology department, it is generally equipped with an extracorporeal high-frequency hyperthermia equipment. However, most extracorporeal high-frequency hyperthermia equipment does not have temperature detection function, which can cause certain inconvenience during use. FJINNO manufactures and produces tumor temperature measurement systems for high-frequency hyperthermia devices in the field of oncology.
Temperature measurement is an important technique to ensure the quality of hyperthermia. To ensure effectiveness, it is necessary to heat the tumor tissue to a temperature of 43-45 ℃ in the treatment high temperature zone, without damaging the surrounding normal tissue, and ensure that the temperature of the normal tissue is below 40 ℃. In the early days, the heating power was controlled solely based on the patient’s thermal sensation. Nowadays, many thermal therapy machines use intermittent shutdown temperature measurement methods, resulting in large temperature measurement errors. The existing microwave hyperthermia technology, due to the inability to synchronously monitor temperature in real-time during the microwave hyperthermia process, results in unsatisfactory hyperthermia effects, and the safety and reliability of microwave hyperthermia are low.
Medical fiber optic temperature measurement, what kind of thermometer is good for medical use.
Real time accurate temperature measurement is of great significance for ensuring the effectiveness of microwave hyperthermia and protecting normal tissues from damage. The main problem with temperature measurement in the microwave field is the interference of the microwave field on temperature measurement. Due to the use of microwave near-field, a strong electromagnetic field, in microwave hyperthermia machines, when using conventional temperature sensors for temperature measurement, metal temperature probes and wires made of metal materials will generate induced currents under high-frequency electromagnetic fields. The voltage drop on the input circuit of the sensor and useful signals will be superimposed and sent to the subsequent measurement circuit, directly becoming interference signals. At the same time, the induced current will generate Ohmic heat on the probe and wire, causing its own temperature to rise and causing measurement errors. Due to the skin effect and eddy current effect of conductors, the surface current density of conductors increases with the frequency of the electromagnetic field, resulting in more severe self heating of the input circuit.
Thermotherapy fluorescence fiber optic temperature measurement
The installation of a fluorescence fiber temperature measurement and temperature measurement integrated device in microwave hyperthermia solves the problem of real-time temperature monitoring that cannot be achieved synchronously in the existing microwave hyperthermia process, which is conducive to improving the effectiveness of hyperthermia and improving the safety and reliability of microwave hyperthermia. By using a temperature measurement system to detect the temperature information at the lesion in real-time, and using an industrial computer to control the output power of the microwave output system based on the temperature information, a closed-loop control of temperature and output power is formed. On the one hand, it ensures the microwave hyperthermia temperature at the lesion, which is conducive to improving the effectiveness of hyperthermia; On the other hand, avoiding excessive temperature of normal tissues around the lesion during hyperthermia can improve the safety and reliability of microwave hyperthermia.
