Abstract
A temperature measuring device based on the vascular intervention technology comprises a vascular intervention catheter, a t-branch pipe, an optical fiber temperature sensor and an optical fiber temperature measuring device. The t-branch pipe is connected with the vascular intervention catheter. One path of the t-branch pipe is connected with a medication injection pipeline. The optical fiber temperature sensor stretches into a blood vessel from another path of the t-branch pipe and penetrates through the vascular intervention catheter connected with the t-branch pipe. The space for medication circulation is formed between the peripheral wall of the optical fiber temperature sensor and the inner wall of the vascular intervention catheter. The optical fiber temperature measuring device is connected with the optical fiber temperature sensor. During temperature measurement, the vascular intervention catheter stretches into target tissue inside the body along the blood vessel, and the optical fiber temperature sensor stretches into the blood vessel along the t-branch pipe and the vascular intervention catheter to reach the far end face of the blood vessel where the vascular intervention catheter is located. The optical fiber temperature sensor is connected with the optical fiber temperature measuring device to measure the temperature of the target tissue. According to the temperature measuring device, the optical fiber temperature sensor is adopted for stretching into the blood vessel by means of the vascular intervention catheter to reach the position where the target tissue is located, the temperature measuring function is achieved, the temperature measuring precision is high, and the temperature measuring speed is high.
