Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high pressure oxygen chamber,

The present invention relates to a high-pressure oxygen chamber capable of controlling an internal temperature generated in a high-pressure oxygen chamber used in medical and healthcare applications.

Hyperbaric oxygen therapy is a treatment that creates an environment of higher pressure than atmospheric pressure, allowing the patient to ingest a high concentration of oxygen to obtain soluble oxygen. This increases the oxygen concentration in the patient's body and improves hypoxia. Types of pressurized gas include oxygen, air, and mixed gas. The high pressure environment corresponds to a pressure of 2 to 3 atm or more. High-pressure oxygen therapy devices have been steadily being studied in the United States and Europe since it was first designed and designed by Henshaw in 1662 for medical research. The chamber of hyperbaric oxygen therapy may have a single or multiple chamber structure to treat one or more patients.

Korean Patent Registration No. 10-0561209 discloses a deep open-type high-pressure oxygen therapy device. The high-pressure oxygen therapy device includes a chamber in which airtightness is maintained when the patient enters and exits, oxygen and compressed air are injected into the chamber, a plurality of reinforcing members installed in the chamber in the longitudinal and lateral directions to house the patient, An oxygen supplying means for supplying oxygen, and a supporting member for supporting the bottom surface of the chamber. A patient accommodated in the chamber is stably accommodated by a plurality of reinforcing members, and oxygen is supplied to the inside of the chamber by oxygen supplying means to treat the patient's disease.

Since the chamber for high pressure oxygen treatment (hereinafter, referred to as a high-pressure oxygen chamber) needs to maintain the air (oxygen) pressure higher than the atmospheric pressure as in the prior art document, it has a constitution of increasing the pressure by sucking gas in a limited chamber volume. Therefore, the temperature T is raised when the pressure P is high and the volume V in the chamber is constant by the Boyle-Charles's law (PV = constant) and the state spinning formula (PV = nRT) The temperature is lowered. Therefore, the patient inside the chamber generally senses the temperature rise during the pressurization due to the intake air and feels the temperature decrease during the decompression process due to the exhaust, compared with when the chamber is initially inserted into the chamber.

At this time, depending on the degree of pressure rise and fall, the patient often feels very severe heat or cold. For example, in the case of a multi-use high-pressure oxygen chamber, since the pressure rise width is large, the temperature at the initial start temperature (about 20 degrees) reaches a maximum of 35 degrees or more when pressurized and a maximum of 10 degrees or less when decompressed. This can be a problem not only to be reluctant to enter the high-pressure oxygen chamber, but also to cause secondary disease in patients with heart disease or sickness.

In order to solve this problem, as a conventional technology, there is a heat generating device, for example, a pipe pipe in which high-temperature hot water flows in the inside of the chamber, so that the cold due to the temperature decrease is lessened. However, there is still a problem in that it takes time for heat generation and cooling, can not prevent the entire temperature rise / fall in the chamber, and the patient himself can not control the rise / fall of the temperature independently.

The present invention has been studied through the following business to solve such a problem.

Also, in order to clearly illustrate the present invention in the drawings, portions not related to the present invention are omitted, and the same or similar reference numerals denote the same or similar components.

The objects and effects of the present invention can be understood or clarified naturally by the following description, and the objects and effects of the present invention are not limited only by the following description.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, referring to FIG. 1, the overall configuration of a high-pressure oxygen chamber capable of adjusting an internal temperature change according to the present invention will be described.

1, the high-pressure oxygen chamber 10 according to the present invention includes an intake pipe 100 for intake of high-pressure oxygen (O2) from at least one high-pressure oxygen cylinder 600 provided outside, And an exhaust pipe (200) for exhausting air to the outside.

According to a preferred embodiment of the present invention, the high-pressure oxygen chamber 10 has an open hollow cylindrical shape and an opening / closing part (for example, a door opened in one direction) is provided on one side or both sides, Patients who require high-pressure oxygen therapy are accommodated internally. The high-pressure oxygen chamber is available in a variety of sizes to accommodate the capacity (single or single). As described for the purpose of the present invention, the present invention aims to reduce the temperature change caused by internal pressure changes. When the pressure is higher than that for single use, The effect of the invention is greater. Hereinafter, in order to briefly describe the high-pressure oxygen chamber according to the present invention, a description of parts not related to the features of the present invention will be omitted.

The high-pressure oxygen cylinder 600 generally compresses oxygen at high pressure and stores it in an oxygen cylinder, as is commercially available. When the outlet of the high-pressure oxygen cylinder is opened and connected to the intake pipe of the high-pressure oxygen chamber, oxygen in the oxygen cylinder enters the high-pressure oxygen chamber by the high pressure inside the high-pressure oxygen cylinder 600. Although the high pressure oxygen cylinder 600 has been described and illustrated in the detailed description and drawings of the present invention for the purpose of treatment through high pressure oxygen, in practice, only high pressure nitrogen (N2) Can be put together. However, for the sake of brevity, only high-pressure oxygen cylinders are described in the present specification and drawings.

In a preferred embodiment, the temperature of the oxygen in the high-pressure oxygen cylinder 600 is preferably maintained at a temperature (about 20 degrees Celsius) so that a person can generally feel comfortable. In another preferred embodiment, the following structure is adopted in which the high-pressure oxygen cylinder and the high-pressure oxygen chamber are connected so that the oxygen temperature inside the high-pressure oxygen cylinder 600 can be introduced into the high- It may be heated or cooled at a specific temperature (for example, around 20 degrees).

The high-pressure oxygen chamber (10) has an intake pipe (100) connected to the high-pressure oxygen cylinder (600) at one end. The intake pipe 100 may have a pipe shape or a rubber material pipe. The intake pipe serves to introduce high-pressure oxygen discharged from the high-pressure oxygen cylinder 600 into the high-pressure oxygen chamber. The intake pipe 100 may include an intake flow meter for measuring the amount of air (oxygen) passing through the intake pipe 100.

The intake pipe (100) has an intake valve (110) for regulating the amount of oxygen entering into the high-pressure oxygen chamber. The acid air intake valve can be a general gas control valve that generally controls the amount of gas passing through and / or closing the interior of the tubular shape. The intake valve 110 is a proportional control valve that moves in conjunction with the exhaust valve 210, which will be described below.

The high-pressure oxygen chamber has an exhaust pipe (200) for exhausting the air inside the other end to the outside. The exhaust pipe (200) has an exhaust flow meter for measuring the amount of air exhausted to the inside thereof, The exhaust valve 210 may be provided.

The exhaust valve 210 is a gas control valve similar in mechanical structure to the above-described intake valve. However, the opening and closing degree of the intake valve 110 is controlled in proportion to the degree of opening and closing of the exhaust valve 210. That is, the exhaust valve 210 is a proportional control valve in which the operator of the high-pressure oxygen chamber directly controls the degree of opening / closing through the control unit, and the intake valve 110 is controlled in proportion to the opening / closing degree of the exhaust valve.

As described above, the high-pressure oxygen chamber 10 continuously uses a circulating pressure-pressurizing system in which air is sucked from the intake valve and exhausted from the exhaust valve. In the case of such a circulating pressure-pressurizing method, the rise / fall of the internal pressure of the high-pressure oxygen chamber is determined by the difference between the amount of the intake air and the amount of the exhausted air. For example, when the amount of air exhausted by the exhaust valve is 100 lpm and the amount of air (oxygen) drawn by the intake valve is 400 lpm, air (oxygen) enters the high-pressure oxygen chamber by 300 lpm Therefore, the pressure rise is caused by that much. When this level of exhaust / intake is maintained, the pressure rises at an air pressure higher than the initial air pressure in the chamber. Likewise, when the pressure is reduced, the amount of air to be exhausted is set to be larger than the amount of air to be inhaled. At this time, as described above, the intake valve is opened / closed in proportion to the exhaust valve. With the introduction of the air circulation pressure application method, the internal air exchange / ventilation can be continuously performed, and at the same time, the pressure in the chamber can be increased / decreased as desired.

However, in this case, as described in the background art, a temperature change due to pressure rise / fall occurs. In order to detect and mitigate such a temperature change, the present invention includes the following temperature sensor 410 and controls the degree of opening and closing of the intake and exhaust valves in conjunction with the temperature sensor 410. [

The state detection sensor device 400 is a sensor for detecting temperature, pressure, air components, etc. in the high-pressure oxygen chamber. In this example, the temperature detection sensor 410 and the air pressure detection sensor 420 exist. The temperature sensing sensor 410 is located at least one inside the high-pressure oxygen chamber and periodically senses the temperature change in the high-pressure oxygen chamber. In addition, a pressure sensor 420 and an air component sensor for analyzing components in the air may be provided. These state detection sensors are well known in the art and will not be described in detail so as to explain the features of the present invention clearly.

The control unit 300 receives the temperature change value sensed by the temperature sensing sensor 410 and controls the opening and closing degree of the intake and exhaust valves. FIG. 2 is a flowchart illustrating a process of controlling intake and exhaust valves after sensing temperature in the controller 300. Referring to FIG. This will be described below with reference to Fig.

First, the temperature sensor measures the starting temperature (T ₀ ) and then periodically measures the current temperature (T _N ). (T _H ) and a lowering limit temperature (T _L ) based on the temperature change value (T ₀ - T _N ) = ΔT obtained by subtracting the start temperature from the current temperature from the temperature change value ΔT ).

In this case, when the temperature is increased, the temperature change value ? T is compared with the rising limit temperature (T _H ). If the temperature change value is larger than the rising limit temperature value, It is assumed that a temperature rise has occurred and a process for decreasing the temperature is performed. If the temperature change value is equal to or smaller than the rising limit temperature value, the amount of exhaust air and intake air of the present exhaust valve and the intake valve is maintained.

In order to reduce the temperature, the control unit first opens the exhaust valve further to increase the amount of exhaust air. Then, as described above, the control unit opens the intake valve in proportion to the exhaust valve to increase the amount of air to be intake. At this time, since the air pressure in the chamber must be raised, the amount of air passing through the intake valve should naturally be larger than the amount of air passing through the exhaust valve.

As described above, since the exhaust valve and the intake valve are opened and closed interlocked and in proportion to each other, the pressure inside the chamber is continuously increased, but when the inside of the chamber is viewed from the inside of the chamber, Since the oxygen chamber air is freshly introduced, the temperature rise can be prevented.

Then, the temperature sensor 410 measures the present temperature as the starting temperature and measures the present temperature again ((T _N -> T ₀ )). Thereafter, the process is repeated until the target pressure is reached .

In the case of the depressurization step in which the temperature falls, an operation opposite to the above-described depressurization is performed. In the case of the decompression process, when the temperature change value ? T is compared with the lowering limit temperature T _L , if the temperature change value is smaller than the lower limit temperature value, a temperature lowering occurs to adversely affect the patient And performs a process for raising the temperature. At this time, in order to raise the temperature, the control unit adjusts the degree of opening and closing of the exhaust valve to reduce the amount of exhausted air. As described above, the control unit adjusts the opening / closing degree of the intake valve in proportion to the exhaust valve to reduce the amount of intake air. As described above, also in this case, since the air pressure in the chamber must be lowered, it is of course necessary that the amount of air passing through the intake valve is smaller than the amount of air passing through the exhaust valve.

In yet another embodiment, the present invention may further include a body temperature sensing device 510 capable of sensing the body temperature of the patient in contact with the skin of the patient inside the high-pressure oxygen chamber. At this time, the body temperature sensing device may be provided, for example, in the form of a bracelet on the wrist of the patient. As a preferred embodiment, a patient generally entering the high-pressure oxygen chamber enters the antistatic wrist bracelet which can cause a fire or the like in the high-pressure oxygen chamber since most of the clothes are removed or replaced with a discharge that does not generate static electricity, A sensing device may be provided. This is particularly effective in patients who are unconscious and unable to express their opinions about excessive temperature changes.

At this time, the control unit controls the exhaust valve to regulate the flow rate of air exhausted in accordance with the body temperature change sensed by the body temperature sensing apparatus. For example, when the body temperature rises / falls to a certain temperature or higher, it is determined that the temperature inside the chamber has risen / lowered excessively. Thus, as in the case where the temperature rises above the rising / Adjust the valve to raise or lower the temperature.

As another preferred embodiment, it is preferable that a temperature control button 520 is provided inside the high-pressure oxygen chamber to control the flow rate of the air exhausted from the exhaust valve by operation of the patient. This is because, unlike the temperature control method that is automatically controlled, the patient can raise or lower the temperature according to his or her own self-judgment, thereby allowing the patient to feel comfortable in his or her own environment in the high- There is a controllable effect.

It will be apparent to those skilled in the art that various modifications, additions and substitutions are possible, without departing from the spirit and scope of the invention as defined by the appended claims. Should be regarded as belonging to the above-mentioned patent claims.
