Precise temperature control tumor therapy device

Abstract

The invention relates to a precise temperature control tumor treatment instrument, which includes a data processing control unit with a touch display screen, a plurality of A / D conversion circuit units, a PID temperature control system, a plurality of temperature measuring sensors (2) and a plurality of temperature A controllable heater (1), the output ends of the plurality of temperature measuring sensors (2) are respectively connected to the input end of the data processing control unit with a touch screen through an A / D conversion circuit unit; the plurality of temperature controllable The temperature measurement output terminals of the heater (1) are respectively connected to the input terminals of the PID temperature control system through one of the A / D conversion circuit units. The invention discloses a precise temperature control tumor treatment instrument, which can fully kill tumor tissue at an ideal temperature. At the same time, since the heating temperature can be precisely controlled, it is guaranteed that normal human biological tissues will not be damaged.

Description

technical field [0001] The application date of this invention is November 10, 2010, the application number is: 201010537185.1, and the divisional application of the invention patent application titled "precise temperature control tumor therapeutic apparatus and its control method". The invention relates to a tumor therapeutic apparatus, in particular to a therapeutic apparatus for treating tumors by means of heat. 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...

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 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 artificial 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
