More specifically, it relates to a door for a high-pressure oxygen chamber in which pressure resistance is improved by forming a reinforcing layer between a first outer wall and a second outer wall. Background Technology

[0002] A hyperbaric oxygen chamber is a primary piece of equipment used in hyperbaric oxygen therapy, which treats patients using high-pressure oxygen. Hyperbaric oxygen therapy is a treatment method in which patients breathe 100% pure or very high-concentration oxygen for one to two hours under a pressure higher than that of a normal breathing environment. It is used to improve the efficacy and quality of treatment by effectively supplying oxygen to tissue cells damaged by decompression sickness, trauma, inflammation, edema, and bacterial infections, and recently, it has also become widely used as a means to accelerate the recovery speed of athletes recovering from injuries. Since this hyperbaric oxygen therapy utilizes high-pressure oxygen, there is a risk of fire or explosion accidents; therefore, it is necessary to prevent oxygen leakage from the chamber's inlet and outlet.

[0003] To this end, the door provided at the entrance of the chamber must withstand the high pressure inside the chamber while sealing the entrance to prevent high-pressure oxygen from leaking to the outside. The present invention proposes a door for a high-pressure oxygen chamber with improved pressure resistance. Prior art literature

Furthermore, in describing the present invention, if it is determined that a detailed description of known technologies related to the present invention may unnecessarily obscure the essence of the invention, such detailed description will be omitted.

[0020] Hereinafter, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments disclosed below. Furthermore, in order to clearly disclose the present invention in the drawings, parts unrelated to the present invention have been omitted, and identical or similar reference numerals in the drawings indicate identical or similar components.

[0023] First, a door for a high-pressure oxygen chamber according to the present invention will be described with reference to FIGS. 1 to 5. Subsequently, the overall configuration of a high-pressure oxygen chamber in which the door for a high-pressure oxygen chamber according to the present invention is installed will be described with reference to FIGS. 6 to 11.

[0024] Hereinafter, a door for a high-pressure oxygen chamber according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. FIG. 1 is an exploded perspective view of a door (D) for a high-pressure oxygen chamber according to an embodiment of the present invention, and FIG. 2 is a plan view of a door (D) for a high-pressure oxygen chamber according to an embodiment of the present invention.

[0025] Referring to FIGS. 1 and 2, a door (D) for a high-pressure oxygen chamber according to one embodiment of the present invention comprises a first outer wall (10), a second outer wall (20), and a reinforcing layer (30) installed between the first outer wall (10) and the second outer wall (20). A detailed description of the reinforcing layer (30) will be provided later with reference to FIGS. 3 and 5.

[0026] The first outer wall (10) is configured to be exposed to the outside of the chamber (C) and is provided in the shape of a rounded rectangular flat plate with a pressure gradient (P) formed at the corner. By forming a pressure gradient (P) at the corner of the first outer wall (10), the risk of damage to the door (D) due to the pressure of high-pressure oxygen inside the chamber (C) can be reduced.

[0027] The second outer wall (20) is configured to face the inside of the chamber (C), is provided with a shape corresponding to the first outer wall (10), and is installed spaced apart from the first outer wall (10) by a predetermined distance. With the second outer wall (20) further provided, the first outer wall (10) is provided to further include a connecting plate (11) having a first fastener (H1) formed thereon so as to be integrally connected to the second outer wall (20).

[0028] The second outer wall (20) includes a second fastener (H2) at a position corresponding to the first fastener (H1) formed on the connecting plate (11), and is installed by being integrally connected to the first outer wall (10) by a fastening part that penetrates the first fastener (H1) and the second fastener (H2).

[0030] FIG. 3 is a plan view showing a reinforcing layer (30) installed on the first outer wall (10) of a door (D) for a high-pressure oxygen chamber according to one embodiment of the present invention, and FIG. 5 is a perspective view showing a reinforcing layer (30) installed on the first outer wall (10) of a door (D) for a high-pressure oxygen chamber according to one embodiment of the present invention.

[0031] Referring to FIGS. 3 and 5, the reinforcing layer (30) is installed between the first outer wall (10) and the second outer wall (20) spaced apart by a predetermined interval. Specifically, the reinforcing layer (30) is provided in a shape corresponding to the first outer wall (10) to distribute and support external forces applied to the first outer wall (10) or the second outer wall (20), and it is preferable that a plurality of space portions (E) spaced apart by a predetermined interval are formed to have a grid shape.

[0032] The space section (E) is configured to include a first space section (E1) formed at the four corners of the reinforcing layer (30), a second space section (E2) formed at both left and right ends of the reinforcing layer (30), and a third space section (E3) formed between the first space section (E1) and the second space section (E2), and it is preferable that the second space section (E2) be formed to have a larger area than the third space section (E3).

[0033] As a more preferred embodiment for the space portion (E), a fourth space portion (E4) may be formed at a position corresponding to the connecting plate (11) so that the upper surface of the connecting plate (11) formed on the first outer wall (10) contacts the lower surface of the second outer wall (20). Specifically, the fourth space portion (E4) is formed to have a larger area than the second space portion (E2) so that the connecting plate (11) can contact the second outer wall (10) without interference from the reinforcing layer (30). By forming the fourth space portion (E4), the first outer wall (10) and the second outer wall (20) can be joined as a single unit by making more secure contact through the connecting plate (11).

[0035] Hereinafter, a high-pressure oxygen chamber (C) having a door for a high-pressure oxygen chamber installed according to an embodiment of the present invention will be described in detail with reference to FIGS. 6 to 11. FIG. 6 is a perspective view of a high-pressure oxygen chamber (C) having a door for a high-pressure oxygen chamber installed according to an embodiment of the present invention, and FIG. 7 is an internal perspective view of a high-pressure oxygen chamber (C) according to an embodiment of the present invention.

[0036] A high-pressure oxygen chamber having a door installed according to one embodiment of the present invention comprises a chamber (C) providing a space for treating a patient, a door (D) for a patient and a worker to enter and exit the plurality of chambers, and a reinforcing member (400) that prevents damage to the chamber from external forces. Here, it is preferable that at least a portion of the chamber (C), the door (D), and the reinforcing member (400) be made of a material such as aluminum alloy, reinforced glass, or polyurethane.

[0037] The chamber (C) is configured to provide a treatment space for a patient, and is sealed internally to receive high-pressure air or high-pressure oxygen from a separate fluid supply unit (F) to perform treatment on the patient. Specifically, the fluid supply unit (F) is installed inside at least one of the first chamber (100), the second chamber (200), and the third chamber (300) to be described later, and supplies air or oxygen within a predetermined pressure range. The predetermined pressure range is preferably set to 2 to 3 atm, and most preferably to 3 atm.

[0038] It is preferable that the chamber (C) be provided in the shape of a cuboid to facilitate transportation and storage, but any shape capable of forming an internal space is sufficient without being restricted by the shape. Additionally, since a door (D) is provided at the front or rear of the chamber (C), patients and workers can enter and exit more easily. In a more preferred embodiment, a pressure gradient section (P) is further provided at the apex of the chamber (C) to prevent excessively high pressure from pressurizing the apex of the chamber (C).

[0039] The chamber (C) basically has a space formed inside to accommodate a patient, and can be provided in various sizes depending on the number of patients accommodated, and can be provided in various shapes such as a rectangular prism and a cylinder. As an example, the chamber (C) on which the door for the high-pressure oxygen chamber according to the present invention is provided in the shape of a cuboid with rounded corners and is provided with a metal material such as an aluminum alloy for robustness. In addition, the door (D) for the high-pressure oxygen chamber according to the present invention, which is formed in the chamber (C) and opens and closes the chamber (C) through hinge movement, is also described as being provided with an aluminum alloy.

[0040] The high-pressure oxygen chamber (C) on which the door for the high-pressure oxygen chamber according to the present invention is installed is provided with a triple structure of a first chamber (100), a second chamber (200), and a third chamber (300). A detailed description thereof will be provided later with reference to FIGS. 9 to 11.

[0041] The door (D) is configured for access to and from the chamber (C) and for maintaining airtightness of the chamber (C). Specifically, each door (D) is located at the front or rear of the chamber (C). Here, the door (D) located at the front of the chamber (C) may be provided to be larger than the size of the body to allow for faster and easier access for patients and workers. Additionally, the door (D) is provided with a reinforcing layer (30) formed to improve pressure resistance. Through this, airtightness can be firmly maintained even if pressure inside the chamber (C) is applied to the door (D). A detailed description of the door (D) will be provided later with reference to FIGS. 1 to 5.

[0042] Meanwhile, the doors (D) are each opened toward the inner direction of the chamber (C). This is to prevent damage to the doors (D) due to high pressure and subsequent accidents during the opening process. In other words, since the doors (D) are opened toward the inner direction of the chamber (C), they are prevented from opening at an excessively fast speed due to the air located inside the chamber (C) compared to when they are opened toward the outer direction, thus preventing damage.

[0043] The reinforcing member (400) is configured to protect the chamber (C). Specifically, the reinforcing member (400) can protect the chamber (C) from external forces and minimize material consumption for manufacturing. To this end, the reinforcing member (400) is formed by assembling a plurality of frames and is positioned to surround the upper surface, lower surface, and both sides (referring to the surfaces formed in the upper-left and lower-right directions of FIG. 6) of the chamber (C). Specifically, the reinforcing member (400) is formed in the shape of an H-beam and is formed to protrude outwardly from the upper surface, lower surface, and both sides of the chamber (C). More specifically, a plurality of reinforcing members (400) are formed to surround the upper surface, lower surface, and both sides of the first chamber (100), second chamber (200), and third chamber (300) to be described later, and are installed at a predetermined interval on the outer surfaces of the first chamber (100), second chamber (200), and third chamber (300) to be described later. That is, the reinforcing members (400) are provided in four pieces, each located on the upper surface, lower surface, and both sides of the chamber (C). Accordingly, the inner surface of the reinforcing members (400) is provided to be in contact with the outer surface of the chamber (C). By providing the reinforcing members (400), the chamber (C) can be easily protected from external forces. This has the effect of preventing secondary injuries that may occur when an impact is applied to the patient during the process of transporting and treating the patient.

[0044] A pressure gradient section (P) is further provided in a chamber (C) in which a door for a high-pressure oxygen chamber according to the present invention is installed. The pressure gradient section (P) is provided to prevent damage to the inner wall portion of the chamber (C) caused by high-pressure air and oxygen located inside the chamber (C). As described above, each corner portion of the first chamber (100), the second chamber (200), and the third chamber (300), which will be described later, is further formed with a pressure gradient section (P) having an arc cross-sectional shape that is curved with a predetermined curvature, thereby preventing a rise in pressure inside the first chamber (100), the second chamber (200), and the third chamber (300). More specifically, as the high-pressure fluid located inside the chamber (C) having a square cross-sectional shape applies a greater force to the apex portion of the chamber (C) formed to be angled, the inner wall of the chamber (C) may be damaged. To solve the above-mentioned problems, a pressure gradient section (P) is disclosed in a chamber (C) on which a door for a high-pressure oxygen chamber according to the present invention is installed. The pressure gradient section (P) is located at the vertex portion of the chamber (C) and has an arc-shaped cross-section that is curved with a predetermined curvature. As a result, the chamber (C) has a cross-sectional shape in which the vertex portion of the square is chamfered. By providing the pressure gradient section (P), damage to the chamber (C) can be prevented during the process in which the fluid inside the chamber (C) moves outward and applies pressure to the chamber (C).

[0046] FIG. 11 is an exploded perspective view of a high-pressure oxygen chamber (C) in which a door for a high-pressure oxygen chamber according to one embodiment of the present invention is installed. As described above, the high-pressure oxygen chamber (C) in which a door for a high-pressure oxygen chamber according to one embodiment of the present invention is installed is provided with a triple structure of a first chamber (100), a second chamber (200), and a third chamber (300).

[0047] The first chamber (100) is configured as shown in the lower left corner of FIG. 11, with a first door (D1) provided on one side and a first connecting part (110) provided on the other side that is open. The second chamber (200) is configured as shown in the center of FIG. 11, is located on the other side of the first chamber (100), and a second connecting part (210) is provided on each of the two open sides. The third chamber (300) is configured as shown in the upper right corner of FIG. 11, is located on the side of the second chamber (200) facing the side connected to the first chamber (100), and a third connecting part (310) is provided on the one side that is open.

[0048] The first connecting part (110), the second connecting part (210), and the second connecting part (210) and the third connecting part (310) are detachably connected to each other, and when the first connecting part (110) and the second connecting part (210) and the second connecting part (210) and the third connecting part (310) come into contact, the interior of the first chamber (100), the second chamber (200), and the third chamber (300) is sealed. It is preferable that a window (W) be formed on at least one of the multiple outer surfaces of each of the sealed first chamber (100), the second chamber (200), and the third chamber (300) so that the internal conditions can be checked from the outside.

[0050] FIG. 9 is an internal plan view of a high-pressure oxygen chamber (C) in which a door for a high-pressure oxygen chamber according to one embodiment of the present invention is installed, and FIG. 10 is an internal cross-sectional plan view of a high-pressure oxygen chamber (C) according to one embodiment of the present invention.

[0051] Referring to FIGS. 9 and 10, the second chamber (200) is further provided with a second door (D2) installed inside, and a sealing member made of silicone material inserted into the contact surface between the installed second door (D2) and the second chamber (200) is provided to double-seal the interior of the third chamber (300). By providing the second door (D2), even if the first door (D1) is opened, the pressure inside the third chamber (300) can be maintained without being affected by it. In this way, when accommodating a patient inside the third chamber (300) and transferring the patient to the outside of the chamber (C) after treatment, the door of the first door (D1) is opened first to prevent the patient from experiencing shock due to a sudden change in atmospheric pressure, thereby adjusting the pressure of the first chamber (100) and the second chamber (200) so that it is lower than the pressure inside the third chamber (300) but higher than the pressure outside the chamber (C), and then the second door (D2) is opened so that the patient is not exposed to a sudden change in pressure.

[0052] In FIGS. 9 and 10, the second door (D2) is shown formed at a location within the second chamber (200) that connects to the third chamber (300), but the second door (D2) may be further formed at a location that connects to the first chamber (100). Through this, the pressure inside the first chamber (100), the second chamber (200), and the third chamber (300) can be controlled to be maintained differently.

[0053] In a more preferred embodiment for the third chamber (300), a third door (D3) may be further formed on at least one of the sealed sides or both sides of the third chamber (300). The third door (D3) is configured to allow a patient to quickly escape from the chamber (C) in the event of an emergency inside or outside the chamber (C).

[0055] Hereinafter, preferred embodiments regarding the principle of opening and closing a door for a high-pressure oxygen chamber according to the present invention, installed in a high-pressure oxygen chamber, will be described. To open and close the door for a high-pressure oxygen chamber according to the present invention, an opening and closing module (M) may be further provided in the high-pressure oxygen chamber.

[0056] The opening / closing module (M) is configured to control a door (D) that is hinged by a hinge module to seal the chamber (C), thereby sealing the inside of the chamber (C) by compressing the door (D) toward the inside of the chamber (C). As shown in FIG. 6, it is most preferable for the opening / closing module (M) to be provided on the front of the first chamber (100). However, it is not limited thereto, and the opening / closing module (M) can be provided anywhere on the outside of the chamber (C) in a position that is easy for an operator to control. By providing an opening / closing module (M) that is electrically connected to the hinge module, the operator can control the opening and closing of the door (D) by operating the hinge module through the opening / closing module (M).

[0057] Specifically, when the chamber (C) needs to be sealed, the hinge module presses the door (D) toward the inside of the chamber (C) through the opening / closing module (M), and when the chamber (C) needs to be opened, the hinge module pushes the door (D) toward the outside of the chamber (C) through the opening / closing module (M), thereby controlling the opening and closing of the door (D).

[0058] To this end, a hinge module is formed on one side of a chamber (C) where a door (D) is installed. The hinge module refers to a hinge configuration that is hinge-connected to the door (D) through a connection via a cylindrical rod column or a hinge connection. Specifically, the hinge module is attached to the other edge of the door (D) to rotate, and a rotating member is attached to perform hinge movement. More specifically, rotating members are attached to one end and the other end of the hinge module to perform hinge movement, and the rotating member is a set of members consisting of a pair, and the rotating member is attached to each end of the hinge module to perform hinge movement. Specifically, each end of the pair of rotating members is attached to each end of the hinge module to perform hinge movement.

[0060] Hereinafter, preferred embodiments of a high-pressure oxygen chamber in which a door for a high-pressure oxygen chamber according to the present invention is installed will be described.

[0061] A high-pressure oxygen chamber equipped with a door for a high-pressure oxygen chamber according to the present invention comprises an internal pressure control unit for an external user to control the pressure inside the chamber and an internal pressure display unit that displays the current pressure inside the chamber in real time, and may further comprise an internal pressure sensing sensor that detects the pressure inside the chamber in real time. The internal pressure control unit may be provided in the shape of a rotatable valve, and it is preferable that the internal pressure display unit be configured to display the internal pressure as a scale or a numerical value.

[0062] In another embodiment, a high-pressure oxygen chamber having a door for a high-pressure oxygen chamber according to the present invention may further be provided with an opening / closing indicator that indicates whether the safe door (D) can be opened or closed. The opening / closing indicator is configured to visually indicate whether it is safe to open or close the door in the current state, and may indicate whether it can be opened or closed using an intuitive indicator such as a red lamp and a blue lamp.

[0063] To solve this, the open / close indicator indicates that safe opening / closing is possible only when it receives information that the internal pressure of the chamber obtained through the internal pressure sensing sensor has become below a specific pressure (e.g., 0.05 bar).

[0064] With this configuration, the opening can be opened quickly without waiting for the remaining pressure to dissipate, even if the pressure is somewhat high (0.5 bar) in an emergency situation; meanwhile, when the pressure is completely safe (0.05 bar), it intuitively indicates that it can be opened, allowing even inexperienced users to easily determine whether it can be opened or closed.

[0065] As another embodiment of the opening / closing indicator, a separate lamp or the like may be provided to indicate that, when the pressure is less than the slightly high pressure (0.5 bar) but higher than the safe opening / closing pressure (0.05 bar), it is not completely safe but can be physically and forcibly opened in an emergency situation (emergency opening / closing possible indicator).

[0066] In another embodiment, a high-pressure oxygen chamber having a door for a high-pressure oxygen chamber according to the present invention may further be provided with a high-temperature air injection unit that injects high-temperature air into the interior of the chamber (C), a lighting unit that visually indicates the remaining amount of oxygen inside the chamber (C), a light source unit that irradiates light into the interior of the chamber (C), and a sensor unit that measures whether the chamber (C) is sealed.

[0067] The high-temperature air jet unit sprays high-temperature air. Generally, the temperature inside a hyperbaric oxygen chamber is relatively low because high-pressure oxygen is introduced or discharged. Furthermore, patients admitted to a hyperbaric oxygen chamber are often unconscious due to conditions such as decompression sickness or nitrogen narcosis, or are admitted after surfacing from underwater, so they frequently suffer from hypothermia. Therefore, it is necessary to raise the patient's body temperature to stimulate metabolism and prevent additional diseases caused by hypothermia.

[0068] To this end, a high-pressure oxygen chamber in which a door for a high-pressure oxygen chamber according to the present invention is installed is equipped with a high-temperature air injection unit. The high-temperature air injection unit is installed inside the chamber (C) and can be moved to any position as long as it can effectively inject high-temperature air into the patient. The high-temperature air injection unit is equipped with a fan or similar method to inject high-temperature air, wherein the high-temperature air is provided at a temperature of 20 to 40 degrees Celsius. This is intended to minimize the patient's aversion to the high-temperature air by providing a temperature close to normal human body temperature. In addition, the high-temperature air injection unit operates from the time the door (D) is opened until the time the door (D) is closed to continuously raise the body temperature of the patient placed inside the chamber (C) and to minimize the patient's aversion, thereby injecting high-temperature air.

[0069] The lighting unit is provided for the purpose of indicating the remaining amount of high-pressure oxygen required to treat the patient. Specifically, the amount of high-pressure oxygen required to treat the patient gradually decreases as the patient's condition improves, and the lighting unit serves to indicate this. The lighting unit is provided inside the chamber (C) and is provided in multiple units, and emits light with a preset color into the interior of the chamber (C). When the remaining amount of high-pressure oxygen required to treat the patient is large, the lighting unit emits light with a low illuminance. As treatment progresses and the required amount of high-pressure oxygen gradually decreases, the lighting unit emits light with an increasingly high illuminance. Through this, the patient can gain a sense of psychological stability as they feel the interior of the chamber (C) gradually becoming brighter. Additionally, if the outer surface of the chamber (C) is provided with a material such as transparent tempered glass, the operator can assess the treatment status of the patient inside the chamber (C) at a glance and, in response, open the door (D) of the chamber (C) at an appropriate time. If the chamber (C) is made of a material other than tempered glass, a window (W) is provided on one side of the chamber (C) so that a worker can check the internal conditions of the chamber (C). Therefore, it is possible to prevent the patient from being left inside the chamber (C) even after treatment is finished.

[0070] The sensor unit is configured to measure whether the chamber (C) is sealed. To this end, the sensor unit is installed inside the chamber (C) to measure the amount of air inside the chamber (C) and transmits the measured amount of air to a separately provided control unit.

[0072] The preferred embodiments of the present invention described above are disclosed for illustrative purposes only, and a person skilled in the art with ordinary knowledge of the present invention may make various modifications, changes, and additions within the spirit and scope of the present invention, and such modifications, changes, and additions should be considered to fall within the scope of the above claims. Furthermore, since a person skilled in the art to which the present invention pertains may make various substitutions, modifications, and changes within the scope of the technical spirit of the present invention without departing from it, the present invention is not limited by the aforementioned embodiments and the attached drawings.

[0073] In the exemplary system described above, methods are described based on a flowchart as a series of steps or blocks; however, the present invention is not limited to the order of the steps, and some steps may occur in a different order or simultaneously with other steps as described above. Furthermore, those skilled in the art will understand that the steps shown in the flowchart are not exclusive, and other steps may be included, or one or more steps of the flowchart may be omitted without affecting the scope of the present invention.
