Whole-body cryotherapy system

Abstract

The invention relates to the field of medical devices, in particular to a whole-body cryotherapy system. Cryotherapy can reduce vasoconstriction, cell permeability, local exudation and hemorrhage, local inflammatory edema and achieve anti-inflammatory effect. The nerve excitability decreased, the conduction velocity slowed down, and the pain was relieved. Make muscle reduce excitability and contractility, to achieve the role of spasm relief. Human body surface temperature is one of the important technical indexes of whole body cryotherapy. Whole-body freezing is a process that simulates humanbody from normal temperature environment to extremely cold environment. It is very important to keep the balance of ambient temperature in this process.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a whole body cryotherapy system. Background technique [0002] Cryotherapy shrinks blood vessels, changes cell permeability, reduces local exudation and bleeding, reduces local inflammatory edema, and achieves anti-inflammatory effects; reduces nerve excitability, slows conduction velocity, and achieves pain relief; reduces muscle Excitability and contractility, to achieve the role of antispasmodic. [0003] The body surface temperature of the human body is one of the important technical indicators of whole-body cryotherapy. The body surface temperature of the parts of the human body that need to be measured, such as the head, trunk, upper limbs, and lower limbs, should be monitored. In general, the head temperature should be kept at 17.5 The temperature of the chest and abdomen is kept at about 12.5°C, and the temperature of the upper and lower limbs is kept at about 5°C, otherwi...

Problems solved by technology

It is designed to provide a through hole for volatilizing liquid nitrogen in the human body compartment and adopts the method of gas circulation to adjust the ambient temperature. The ambient temperature in different positions in the compartment will be quite different; the design uses a suction motor and an air bag to ventilate the liquid nitrogen. Air is injected into the bottle, and the liquid nitrogen flows into the liquid nitrogen cavity through pressurization, but due to the time delay of the suction motor blowing into the normal pressure liquid nitrogen tank and the time delay of the air bag releasing the pressure in the normal pressure liquid nitrogen bottle Difficult to match, it will cause too much liquid nitrogen flowing into the liquid nitrogen cavity, and the excess liquid nitrogen cannot be effectively used, resulting in water accumulation and freezing inside the equipment; the structure of liquid nitrogen absorption during design is arranged in the following order from bottom to top: Liquid nitrogen tank, liquid nitrogen dip tube, air bag and liquid nitrogen cavity, but because the through hole of the liquid nitrogen dip tube is connected with the through hole of the liquid nitrogen cavity, part of the liquid nitrogen flowing out of the liquid nitrogen dip tube will Along the through hole of the liquid nitrogen cavity, it flows into the airbag and the normal pressure liquid nitrogen tank, causing the liquid nitrogen dipping tube to freeze, liquid nitrogen pollution, etc.
