Problems solved by technology

[0002] At present, the method of cooling or heating the human body in my country basically adopts the method of body surface temperature regulation, such as using ice packs or ice blankets to cool down. Body surface cooling can achieve the purpose of cooling to a certain extent, but the existing body surface cooling temperature is not easy to control. The operation process is cumbersome, the induction process is long, and it is easy to excessively cool down or heat up
Excessive cooling not only fails to achieve the therapeutic effect, but also easily leads to corresponding complications of patients, and even increases the risk of death; when accidental hypothermia (such as frostbite, shock, etc.) or large area burn patients maintain body temperature, heating is required. The ambient temperature in the operating room is too high, which can easily cause discomfort to the surgeon and nursing staff

Embodiment 1

[0017] as attached figure 1 As shown, the intravascular temperature automatic adjustment device of this embodiment includes a saline bag 1, a peristaltic pump 2, an anti-air valve 3, a thermal adjustment device 4 and a balloon 5, and the saline bag 1, peristaltic pump 2, and anti-air valve 3. The heat regulating device 4 and the balloon 5 are sequentially connected through the catheter 6 to form a closed loop structure. When working, add physiological saline to the saline bag 1, insert the balloon 5 into the left femoral vein next to the groin of the patient, and the heat regulating device 4 can adjust the temperature of the physiological saline according to the control requirements, and the physiological saline is moved along with the peristaltic pump 2. The catheter 6 circulates, and the balloon 5 is used to continuously exchange heat with the blood in the patient's inferior vena cava, so as to achieve the purpose of controlling the temperature of the human body.

Abstract

The invention relates to the technical field of medical human body temperature regulation, in particular to an intravascular thermostat which comprises a saline bag, a peristaltic pump, an air trap, a thermal regulation device and a balloon which are sequentially connected by ducts to form a closed-loop circulation structure. The temperature is regulated by vessels inside the body accurately, quickly and controllably, so that the effect is good, and the risk of corresponding complications and death of patients is greatly reduced.
