Ultralow temperature freeze therapy unit

Abstract

The invention relates to the ultralow temperature treatment field, and especially relates to an ultralow temperature freeze therapy unit comprising a gas chamber and a freeze therapy chamber; an air inlet and an air outlet are arranged between the gas chamber and the freeze therapy chamber; the gas chamber comprises a liquid nitrogen tank, an air bag, a liquid nitrogen cavity, a turbine blower and a gas chamber exhaust port; an air suction motor controls air in/out of the air bag so as to press the liquid nitrogen into the liquid nitrogen cavity; the liquid nitrogen in the liquid nitrogen cavity is vaporized as nitrogen under the turbine blower effect; the nitrogen enters the freeze therapy chamber through the air inlet, circulates in the freeze therapy chamber, enters the gas chamber through the air outlet in the circulation process, and the air outlet of the gas chamber is used for discharging the nitrogen from the gas chamber. The ultralow temperature freeze therapy unit can obviously relieve fatigue after sports, body-building, medical rehabilitation or military training, has less stimulation on human body, has no side effect, so people can easily bear the unit; the liquid nitrogen can be used for freeze therapy, operation is convenient, and the treatment can be done at any time.

Description

technical field [0001] The invention relates to the field of ultra-low temperature therapy, in particular to an ultra-low temperature cold therapy instrument. Background technique [0002] Cold bath therapy is a treatment method that uses freezing of local tissues to destroy or excise tissues in a controlled manner, or cold bath surgery. During the treatment, the tissue is rapidly frozen, the temperature drops below 0°C, the interstitial fluid inside and outside the cells forms ice crystals, the cell structure is destroyed, and then the cells are dehydrated, the lipoproteins in the membrane system are denatured, and the tissue ischemic infarction and nutritional deficiencies. And finally to necrosis, in the process of rewarming, the damaged tissue protein has new antigenic properties, which stimulates the body's immune system and produces an autoimmune reaction. However, traditional cold therapy such as cold water bath, winter swimming, ice cube bath, etc. cannot meet the n...
