Description

GAS ANALYSIS CAPABLE HYPERBARIC OXYGEN CHAMBER}

The present invention relates to a hyperbaric oxygen chamber capable of gas analysis. More specifically, it relates to a high-pressure oxygen chamber capable of measuring and analyzing gas in a high-pressure oxygen chamber and capable of adjusting the pressure in the high-pressure oxygen chamber while maintaining the ratio and concentration of the gas.

In general, a hyperbaric oxygen chamber is a device mainly used for hyperbaric oxygen treatment. Hyperbaric oxygen treatment refers to a treatment that increases the oxygen concentration in a patient's body by supplying oxygen of high purity or 100% concentration in an environment with atmospheric pressure higher than atmospheric pressure. It is used to treat tissue cells damaged by carbon monoxide poisoning, diving sickness, chronic diabetic wounds and complications, necrotizing fasciitis, burns, edema, and bacterial infection. At this time, the concentration of oxygen used for treatment may vary according to the symptoms and severity of the patient, and in general, the concentration of oxygen can be adjusted by mixing other gases in addition to oxygen. In addition, it is important to properly set and control the pressure inside the hyperbaric oxygen chamber in order to reduce the side effects of treatment and maximize the effect.

On the other hand, in order to control the pressure in the chamber in the process of hyperbaric oxygen treatment using a conventional hyperbaric oxygen chamber, the gas mixed in the chamber is supplied or discharged through an intake or exhaust port. In addition, due to the nature of hyperbaric oxygen treatment in which treatment is performed in an enclosed space, carbon dioxide generated from the patient must be discharged to the outside. At this time, it is difficult to discharge while maintaining the composition ratio of the gas, and when resupplying the gas into the chamber after discharge, difficulty arises in supplying the gas in consideration of the composition ratio of the gas remaining in the chamber in order to maintain a certain oxygen concentration. As a way to solve this problem, technologies related to high-pressure oxygen chambers such as Patent Document 1 (No. 10-2077372) and Patent Document 2 (No. 10-2340295) have been developed.

Patent Document 1 (Korean Patent Registration No. 10-2077372) detects the subject's anxiety level in real time by combining physiological anxiety indicators, and based on this, controls the air pressure in the chamber in real time, thereby preventing claustrophobia that may occur in the subject. It relates to a control device capable of minimizing the side effects of the back and improving the treatment effect, and a hyperbaric oxygen treatment system including the same.

However, as a method of controlling the pressure by supplying and blocking oxygen to the chamber, it is difficult to supply or maintain an appropriate oxygen concentration according to the symptoms and severity of the patient, which may cause a problem of poor precision in treatment. In addition, since it takes time in the process of supplying or discharging oxygen to return the pressurized or decompressed pressure back to a certain level, the efficiency of treatment may be reduced.

On the other hand, Patent Document 2 (Korean Patent Registration No. 10-2340295) is a tube-type multi-pressure integrated type that can simultaneously realize positive and negative pressure environments in one chamber by using an oxygen pressure control unit and a negative pressure control unit that control the pressure inside the chamber. It is about the chamber system.

However, in the process of adjusting the pressure by discharging the air in the chamber to the outside, it is not possible to check the components of the gas in the chamber and the oxygen concentration suitable for the purpose of treatment cannot be maintained. In addition, in order to convert the environment in the chamber to a negative or positive pressure, an additional process of controlling the operation of the oxygen pressure controller and the negative pressure controller is essential. losses may occur.

When the piston 520 moves in one direction, the size of the second space is reduced, and the gas that occupies the second space moves to the first space as much as the size of the second space is reduced. The pressure in space increases. In addition, when the pressure inside the body portion 100 increases, the controller 400 sends a control signal to the drive motor 530 to move the piston 520 in the other direction. When the piston 520 moves in the other direction, the size of the second space expands, and as the gas occupying the first space moves to the second space as much as the size of the second space expands, the pressure in the first space increases. It gets lower.

Illustratively, it is assumed that the positive pressure of the first space suitable for treatment is 1, and the positive ratio of oxygen, carbon dioxide and nitrogen is 2:1:1 and is stored in advance as a set value. After the patient enters the first space inside the body and supplies gas from the supply unit to proceed with treatment, in the process of adjusting the pressure in the first space with the pressure control module, the ratio of oxygen, carbon dioxide, and nitrogen is 2:2. Assume that it has been changed to :2. At this time, the gas analysis module detects a change in the ratio of gas and transmits the change to the control unit, and the control unit sends a control signal to the weight supply unit to maintain the set ratio of 2:1:1. The supply unit supplies more oxygen to the first space by 2 according to a control signal from the control unit so that the ratio of oxygen, carbon dioxide and nitrogen can be maintained at 2:1:1. At this time, the environmental information collection module detects the pressure in the first space due to the oxygen further supplied from the supply unit and transmits it to the control unit. A healing environment can be created. In addition, since the pressure can be adjusted by supplying gas or driving the pressure control module, it is possible to reduce time and cost loss required to adjust the pressure by supplying gas.
