Problems solved by technology

[0004] The existing human body temperature control system only has a single mode of heating and cooling, but in some operations, the speed of temperature change is too fast or too slow, which may cause adverse effects on the operation
However, in the prior art, the temperature control system mode is single, and different cooling speeds are not adopted for different surgical environments and different patients' own conditions, which adversely affects the surgical effect.

Abstract

The invention discloses a temperature control method of a human body temperature adjusting system. The human body temperature adjusting system comprises a semiconductor heating and refrigeration chip, a water circulating system and a temperature sensor. The control method comprises the following steps: changing the size of a first expected water temperature according to requirements on a temperature change speed, so as to obtain a second expected water temperature; and controlling the temperature change speed according to the second expected water temperature, wherein a control principle of the temperature change speed comprises: the temperature change speed is positively correlated with a temperature difference value, and the temperature difference value refers to a difference value between the second expected water temperature and a measured actual water temperature. The invention further provides a temperature control system corresponding to the method. According to the method and the system, disclosed by the invention, the temperature change speed can be adjusted according to different surgical environments and self-conditions of patients.

Description

technical field [0001] The invention relates to the field of temperature control, in particular to a temperature control method and a control system of a human body temperature regulation system for surgical operations. Background technique [0002] Many surgical procedures require cryogenic conditions. Especially for operations such as neurosurgery and cardiac surgery, it is usually necessary to cool the patient's brain and body after surgery to protect the central nervous system and prevent hemorrhage. [0003] Common surgical cooling devices include semiconductor refrigeration chips, water circuits, water pumps, temperature sensors and other parts. For example, a temperature regulation system disclosed in CN 204501188 U includes a semiconductor refrigeration chip and a water circulation system. Under the action of the water pump, the water in the water circulation system flows through the semiconductor refrigeration sheet to cool down. The semiconductor refrigeration s...
