When the temperature of the water reaches the upper limit of the system set temperature, the temperature control switch Automatically cut off the circuit and stop the heating work of the heater, so as to achieve the purpose of controlling the constant temperature of the water storage tank; the setting of the flow regulating valve is used to adjust the flow of the water cycle; Frostbite of the skin, to achieve the purpose of protecting the skin.

The heat preservation device is a medical-grade rubber container with a cavity inside and good flexibility. The more flexible, medical-grade rubber container increases the surface area in contact with the skin.

The heat preservation device is provided with several through holes through which surgical tools can pass.

There are several heat preservation devices, which are connected in parallel between the flow regulating valve and the water storage tank through connecting pipes, and gaps are formed between adjacent heat preservation devices for surgical tools to pass through.

The advantages of the present invention are: the device can automatically heat the water to the set temperature, and automatically control the water temperature to be constant at the set temperature. The flexible medical-grade rubber container can increase the area in contact with the skin, and the water circulation can ensure that the medical-grade rubber The temperature of the water in the container is constant, thereby preventing the generation of skin frostbite during the operation.

Detailed ways

The content of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

The temperature range of ultra-low temperature tumor eradication operation is -120°C to -140°C, while the temperature control range of circulating hot water is controlled at 43°C to 50°C. The optimal temperature range of circulating hot water for this operation is 45±1 ) °C, the temperature control switch 6 of this device sets the lower limit of the temperature of the circulating hot water to 44 °C, and the upper limit of the temperature is 46 °C. When the temperature of the circulating water is lower than 44 °C, the temperature control switch 6 automatically connects the circuit to make the heater 5 heat and For the water in the water tank 1, when the circulating water temperature is higher than 46° C., the temperature control switch 6 disconnects the circuit, and the heater 5 stops heating. This condition is described in this embodiment.
