Field of the Invention [0001] The present invention relates to an oxygen supply apparatus for an oxygen chamber, and more particularly, to a first oxygen supply apparatus for an oxygen chamber, which comprises a casing unit and a first cooler unit disposed above the casing unit, An air compression unit disposed at a position directly under the first cooler unit to compress air sucked and an air tank unit communicating with the air compressing unit to pressurize the air compressing unit and temporarily store the air cooled by the first cooler unit, A second cooler disposed at an inner side of the casing to generate a horizontal airflow in the casing to cool the air compressing unit and the air tank unit, and a second cooler unit communicating with the air tank unit to remove moisture in the compressed air cooled by the second cooler unit The water filtration unit and the water filtration unit communicate with each other to remove nitrogen in the air that has passed through the water filtration unit, The present invention relates to an oxygen supply device for a chamber, including an oxygen generating part provided to increase the oxygen concentration in the chamber and an air discharging part provided to send air containing high-concentration oxygen that has passed through the oxygen generating part to the oxygen chamber.

Generally, high-pressure oxygen therapy using a high-pressure oxygen chamber is a treatment that creates a pressure environment of 2 to 3 atmospheres or higher, which is higher than atmospheric pressure, so that a patient can inhale oxygen at a high concentration to obtain soluble oxygen. This increases the oxygen concentration in the patient's body and improves hypoxia. Such high oxygen uptake increases the amount of oxygen bound to hemoglobin, and thus increases the risk of fractures, orthopedic diseases such as ligament injuries, acute attacks, suffocating encephalopathy, In addition to neurological disorders, it is also known to have therapeutic efficacy in emergency conditions such as burns and carbon monoxide poisoning.

In recent years, treatment with oxygen inhaled by high concentration has been used for treatment of limbic cold, which is cold and cold, recovery of chronic fatigue and myalgia, prevention and treatment of dementia and cerebral infarction, and alleviation of diabetes and hypertension.

Conventional technologies related to an oxygen chamber for treating a patient using oxygen include a 'cylinder type high-pressure oxygen chamber' (hereinafter referred to as 'prior art 1') filed by Korean Patent Application No. 2009-0103887 and a Korean patent application No. 2012 Quot; Oxygen Capsule Entrance Door and Oxygen Supply Control Device " (hereinafter referred to as " Prior Art 2 ") filed as -0157850.

BACKGROUND ART [0002] Conventional technology 1 relates to a cylinder type high-pressure oxygen chamber, in which a temperature and a pressure are controlled by an input / output control method in a cylindrical chamber and a door is opened / The present invention proposes a method of automatically opening and closing a sliding door by using another air line or automatically controlling the oxygen inside the sliding door. In particular, in the related art 2, the air door of the oxygen tank is used to pressurize the door, .

In this type of oxygen chamber, generally, pressurized gas is used by using high-pressure oxygen cylinders such as oxygen, air, and mixed gas, and high-pressure oxygen itself is used as a secondary medical treatment due to fire, explosion, An accident may occur, so the medical practitioner or nurse monitors the oxygen chamber while the patient is being treated in the oxygen chamber.

The monitoring time is usually 1 to 2 hours, which is a major reason for the medical staff to hesitate to treat the oxygen chamber.

Also, there are increasing cases in which oxygen chambers are used in daily life environments.

In other words, the oxygen chamber is used for restoration and cosmetic purposes after exercise. The high pressure oxygen has many rejections such as fear to be treated by the general public, and the risk factor inherent in high pressure oxygen still exists.
