Portable oxygen-inhalation heater based on phase-change thermal storage

Abstract

The invention discloses a portable oxygen-inhalation heater based on phase-change thermal storage. The portable oxygen-inhalation heater based on the phase-change thermal storage comprises a heater housing, a heat exchange tube, and an electric heater; a thermal-insulation inner shell is arranged inside the heater housing; a phase-change energy storage cavity is provided inside the thermal-insulation inner shell; a thermal-insulation filling cavity is formed between an inner wall of the heater housing and an outer wall of the thermal-insulation inner shell; an air inlet throttle valve and an air outlet pipe joint are arranged at the top of the heater housing; an electric heater is arranged inside phase-change energy storage cavity of the thermal-insulation inner shell; an external power supply cord, which is electrically connected with the electric heater, is arranged on the heater housing; an air inlet pipe joint communicates with a side part of the air inlet throttle valve; the heatexchange tube is placed inside the phase-change energy storage cavity; an air inlet end of the heat exchange tube communicates with the air inlet throttle valve; and an air outlet end of the heat exchange tube communicates with the air outlet pipe joint in a sealed way. The portable oxygen-inhalation heater based on the phase-change thermal storage is capable of heating oxygen and performing precise adjustment on oxygen inhalation temperature, and has the advantages of being strong in portability, high in practicability, long in working time, adjustable in oxygen inhalation temperature, high in degree of oxygen inhalation comfort and the like.

Description

technical field [0001] The invention relates to clinical medical auxiliary treatment equipment, in particular to a portable oxygen heater based on phase change heat storage. Background technique [0002] Oxygen inhalation is a commonly used auxiliary treatment method in clinical practice. The traditional medical oxygen inhalation device realizes simple oxygen flow control and oxygen humidification. In relatively cold winter, the temperature of inhaled oxygen is much lower than that of the human body, causing discomfort to patients. There are few devices for heating inhaled oxygen in the prior art, such as patent No. ZL00247498.0, ZL00228278.X, ZL93231052.4 and other patents Heating oxygen inhalation is realized by different methods, which can improve the comfort of oxygen inhalation for patients. However, the above heating methods are all bedside fixed heating methods, which need to be directly inserted into electric energy before heating oxygen inhalation. For those who nee...

AI Technical Summary

Problems solved by technology

[0004] In recent years, high-altitude outdoor sports have developed rapidly, but due to the low oxygen concentration in the plateau, outdoor sportsmen often suffer from hypoxic symptoms, even life-threatening

Conventional outdoor portable oxygen cylinders have small oxygen storage capacity and short use time, which cannot meet the needs of long-term outdoor sports

Pioneer series Carl liquid oxygen respirator and Chengdu Yixunyuan portable liquid oxygen respirator have been developed successively in the market. A portable liquid oxygen respirator weighing less than 2 kg can continuously supply oxygen for more than 8 hours after being filled with liquid oxygen. It completely solves the defects of the traditional medical oxygen supply method due to the bulky, heavy and inconvenient portability of high-pressure oxygen cylinders

However, traditional portable oxygen cylinders do not have a corresponding portable oxygen inhalation heating device. In the cold winter, the temperature of inhaled oxygen cannot be heated, resulting in poor oxygen inhalation comfort, especially when altitude sickness or pulmonary edema occurs, which will aggravate inhalation. Oxygen's condition and discomfort

Portable liquid oxygen respirators have been developed rapidly due to the use of liquid oxygen for oxygen storage, large oxygen storage capacity, and long-lasting use. The output oxygen temperature is low, especially in the cold outdoor environment, which brings serious discomfort to the oxygen inhaler, and there is no good solution at present
