Precise temperature-controlling tumor therapeutic apparatus and control method thereof

Abstract

The invention relates to a precise temperature-controlling tumor therapeutic apparatus, which comprises a data processing control unit having a touch display screen, a plurality of A / D switching circuit units, a PID temperature-controlling system, a plurality of temperature-sensing sensors (2) and a plurality of temperature controllable heaters (1), wherein the output ends of the temperature-sensing sensors (2) are respectively connected to an input end of the data processing control unit having a touch display screen through one A / D switching circuit unit, and the temperature sensing output ends of the temperature controllable heaters (1) are respectively connected to an input end of the PID temperature-controlling system through one A / D switching circuit unit. The precise temperature-controlling tumor therapeutic apparatus of the invention can thoroughly kill tumor tissues under proper temperature and can precisely control the heating temperature so as to prevent the normal biologic tissues of human body from being hurt.

Description

technical field [0001] The invention relates to a tumor therapeutic apparatus and a control method thereof, in particular to a therapeutic apparatus for treating tumors by means of heat and a control method thereof. Background technique [0002] It is generally accepted in the medical field that tumor cells will die when heated to 42.5°C, while normal human tissue will lose tissue function when heated to 45°C-47°C. Therefore, the medical field adopts tumor hyperthermia as a method for treating tumors and is widely used. The ideal treatment method is: on the one hand, it should be ensured that all tumor tissues are heated to 42.5°C and maintained for a period of time; on the other hand, normal tissues should not be heated above 45°C, so as not to damage the normal functions of the human body. However, the tumor therapy instruments currently on the market do not have the function of accurate temperature measurement and temperature control. [0003] Although the patent of rev...

AI Technical Summary

Problems solved by technology

[0004] (1) Although it is called "reverse temperature control combined probe type tumor hyperthermia instrument", it only discloses a probe heating needle, and cannot be called a tumor hyperthermia instrument

[0005] (2) Since it does not disclose any temperature control device, it is impossible to ensure that the tumor tissue can be kept at a set temperature value or 42.5°C, and accurate heating temperature is the basis of tumor hyperthermia

like figure 1 As shown, the temperature overshoot effect will occur in the heating process of tumor tissue. If manual control is adopted, the heating temperature will fluctuate in a large range from the predetermined value or the ideal value (42.5°C), and the temperature cannot be stabilized.

This will seriously affect the effect of treatment, and even damage normal human tissues and organs, making it impossible to achieve the purpose of tumor treatment
