An ultra-low temperature local cold therapy system

Abstract

In the ultra-low temperature local cold therapy system provided by the present invention, the air enters the cooler (21) after being compressed by the air compressor (20), and then passes through the buffer tank (30) sequentially after being cooled by the cooler (21). ), the steam-water separator (32), the oil separator (33) and the first flow regulating valve (34) enter the evaporator (11), and after the evaporator (11) The gas forms cold air after passing through the heater (40) and the shut-off valve (41) in turn, and the cold air can act on the affected area. The ultra-low temperature local cold therapy system provided by the present invention overcomes the prior art and uses liquid nitrogen as a The defect of medium refrigeration, low-temperature refrigerator is used as the cooling source, and the effect on the affected area is cold air, the oxygen concentration is suitable, and the human body feels comfortable. Through local ultra-low temperature, the affected area, face, abdomen, etc. are treated more targetedly to achieve rapid local anti-inflammation , Beauty, weight loss and fat reduction purposes.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an ultra-low temperature local cold therapy system. Background technique [0002] Ultra-low temperature local cryotherapy instrument is a health care treatment method that uses ultra-low temperature to perform cryotherapy on local affected parts of the human body. For example, the cold environment stimulates the local tissue to produce an antagonistic protective response, allowing the body to spontaneously produce anti-inflammatory factors to achieve the purpose of reducing inflammation in the affected area; after repeated facial ultra-low temperature cold therapy, your skin will be significantly improved, including: freckle removal, removal of Acne, deep hydration, dilute fine lines, etc. [0003] Most of the current local cold therapy equipment uses liquid nitrogen for direct evaporative cooling. However, the equipment using the above scheme needs to consume a lot of liq...

AI Technical Summary

Problems solved by technology

[0003] Most of the current local cold therapy equipment adopts liquid nitrogen direct evaporative refrigeration. However, the equipment using the above scheme needs to consume a large amount of liquid nitrogen, so the equipment needs professional operation and training, and needs to be replenished regularly. At the same time, the evaporation of liquid nitrogen will produce High concentration of nitrogen, there is a risk of suffocation in use

In order to solve the above problems, the patent CN201620900020.9 proposes to use a semiconductor refrigerator as a cooling source. However, the cooling temperature of the semiconductor refrigerator is limited, the lowest can only reach -40°C, and it cannot completely replace the function of liquid nitrogen.
