Description

Technical Field

[0001] This invention relates to the field of hyperbaric oxygen chamber technology, and specifically to a hyperbaric oxygen chamber body. Background Technology

[0002] Hyperbaric oxygen therapy is a medical treatment that increases blood oxygen concentration by raising environmental pressure and oxygen content, and it is widely used in the field of rehabilitation medicine. As the primary treatment equipment, the structural stability of the hyperbaric oxygen chamber affects the treatment effect and safety. Existing hyperbaric oxygen chambers have significant limitations in pressure-bearing capacity, generally only able to withstand 1.3 atmospheres or less, restricting their further application. For example, patent CN116983166A proposes a vector spherical chamber to optimize pressure distribution. While its spherical structure enhances resistance to deformation, the spherical design reduces space utilization, and the flat door is prone to becoming a structural weak point under high pressure. Summary of the Invention

[0003] To address the problems in the existing technology, this invention proposes a hyperbaric oxygen chamber body.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A hyperbaric oxygen chamber body includes a bottom plate, side plates, a top plate, and a tail plate. The edges of the bottom plate, side plates, top plate, and tail plate are welded together to form a sealed shell. An internal frame is welded to the inner surface of the sealed shell, and an external frame is welded to the outer surface of the sealed shell. The top plate is curved, and a door opening is provided in the front half. A door frame and a door are installed in the door opening, and the door is slidably connected to the side plates.

[0005] To enhance the deformation resistance of the hyperbaric oxygen chamber under high pressure, this invention mainly makes two improvements: First, the door opening is located in the front half of the top plate, utilizing the compressive strength of the curved surface of the top plate to reduce local stress concentration caused by the opening in the side plate, thus avoiding the risk of deformation of the flat plate structure under high pressure; Second, the chamber is reinforced with an internal frame and an external frame, which significantly improves the rigidity of the chamber by constraining the deformation of the shell from both inside and outside the chamber.

[0006] Preferably, the internal frame is distributed on the bottom plate and the side plate, including bottom beams, inner longitudinal beams, inner transverse beams and inner diagonal beams, and all beams are not overlapped to avoid stress concentration.

[0007] Preferably, the bottom plate surface is provided with multiple transverse bottom beams; the inner side of the side plate is provided with inner longitudinal beams, inner transverse beams and inner diagonal beams forming a grid structure; the bottom beams of the bottom plate provide tensile force to suppress the expansion of the cabin to both sides under high pressure, and the grid structure is located below the window to specifically reinforce weak areas and suppress window deformation under high pressure.

[0008] Preferably, the side panel has a window with a window frame. The window provides an additional observation channel, allowing for timely observation of any abnormalities inside the cabin and improving the psychological experience of the patient. The inclination angle of the inner inclined beam is the same as that of the lower edge of the window, and the inner inclined beam is in contact with the lower edge of the window, directly transferring the window stress to the frame and effectively improving the compressive strength of the window edge.

[0009] Preferably, the external frame is distributed on the outer surfaces of the side plates, the top plate, and the tail plate, including a side outer frame, a top crossbeam, and a tail crossbeam, with transverse beams enhancing the lateral stiffness of the cabin; the top crossbeam and the tail crossbeam are arranged transversely, and the top plate has a crossbeam mounting groove for installing the top crossbeam at a corresponding position; the side outer frame has a grid structure, with the grid density concentrated below the window in the middle of the side plate, specifically reinforcing the high-pressure stress concentration area of ​​the side plate.

[0010] Preferably, the side frame is divided into a middle area, a bottom area, a front area, and a rear area. The middle area and the bottom area both adopt a crisscrossing grid structure, with the grid structure in the middle area being the densest. The middle area is located below the window and is attached to the lower edge of the window, and has the same tilt angle as the lower edge of the window, directly supporting the lower edge of the window. The bottom area covers the area between the middle area and the bottom edge of the side panel to prevent sudden stress changes at the bottom of the side panel.

[0011] Preferably, the side frame also includes long longitudinal beams located on both sides of the window. The long longitudinal beams connect the top surface beam at the top of the side panel and the bottom of the side panel to form a main path for longitudinal force transmission, and connect with the middle area, bottom area, front area and rear area, thereby integrating the frames of each area to form an overall pressure-resistant network.

[0012] Preferably, the window frame is fixed to the outside of the side panel; the door frame is installed on the outside of the top panel, covering the front half of the outside of the top panel; the window frame further strengthens the pressure on the window edge, and the door frame disperses the pressure load around the cabin door.

[0013] Preferably, the tail plate is bent into a multi-segment structure and forms an accommodating space at the lower rear of the sealed shell, thereby optimizing the utilization of the cabin space.

[0014] Preferably, the bottom plate, side plate, top plate, and tail plate are all made of steel plate or carbon fiber plate, and the internal frame and the external frame are welded together from square tubes. The square tube structure can reduce the weight of the frame while providing high strength.

[0015] This invention significantly enhances the pressure-bearing capacity of the cabin through double-layer reinforcement of the internal and external frames, supporting treatment environments with a maximum pressure of 1.5 atmospheres. The external frame optimizes stress distribution through non-uniform dense grids and multiple horizontal and vertical beams, effectively suppressing the risk of deformation under high pressure. Meanwhile, the internal frame uses a grid structure to specifically reinforce the window area, achieving higher cabin rigidity and high-pressure sealing stability. Attached Figure Description

Detailed Implementation

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] like Figure 1-3As shown, this embodiment proposes a hyperbaric oxygen chamber body, which is part of a hyperbaric oxygen chamber and includes a base plate 1, side plates 2, a top plate 3, and a tail plate 4. The edges of the base plate 1, side plates 2, top plate 3, and tail plate 4 are welded to form a sealed shell with an internal treatment space for the human body. The base plate 1 is a rectangular flat plate. The side plates 2 are irregularly shaped flat plates, and the bottom of the side plates 2 are welded to the base plate 1. The side plates 2 include a first side plate and a second side plate, which are symmetrically arranged and each has a window. The window has a window frame 201 and a transparent window 202 set in the window frame 201. The transparent window 202 is made of PVC material. The top plate 3 is curved as a whole, and its front and rear ends are welded to the base plate 1 and the tail plate 4, respectively, and its two sides are welded to the two side plates 2. A doorway is opened in the area at the front of the cabin in the top plate 3. A door frame 301 and a hatch 302 are installed in the doorway. The door frame 301 is installed on the outside of the top plate 3, covering the front half of the outer side of the top plate 3. The hatch 302 is slidably connected to the two side plates 2 via tracks. The tail plate 4 is bent into multiple sections. Both ends of the tail plate 4 are welded to the top plate 3 and the bottom plate 1 respectively, and the sides are welded to the two side plates 2. After bending, the tail plate 4 forms a space in the lower rear of the cabin to accommodate pressurization equipment, oxygenation equipment, detection equipment, and control equipment. The bottom plate 1, side plates 2, top plate 3, and tail plate 4 are all made of 4 mm thick laser-cut steel plates.

[0020] like Figure 2 As shown, an internal frame 5 for structural stability is welded inside the cabin, distributed on the bottom plate 1 and two side plates 2. This frame includes a bottom beam 501, inner longitudinal beams 502, inner transverse beams 503, and inner diagonal beams 504, all of which are non-overlapping and are made of cast square tubing. Four transverse bottom beams 501 are provided on the upper surface of the bottom plate 1, with spacings of 300 mm, 448 mm, and 272 mm from front to back. Multiple hatchway track mounting holes are provided on the top and front end of the inner side of the side plate 2 for installing curved hatchway tracks. The foremost bottom beam 501 is positioned to avoid the hatchway tracks. The window on the side plate 2 has an irregular rounded corner shape and is tilted at a certain angle, with the lower edge tilted at an angle of θ1. The window frame 201 is fixed to the outside of the side plate 2. Below the window on the inner side of the side plate 2, there are four intersecting inner longitudinal beams 502, one inner transverse beam 503, and two inner diagonal beams 504. The inner longitudinal beam 502 is connected to the bottom beam 501. The angle of the inner inclined beams 504 is θ1, which is the same as the lower edge of the window. One inner inclined beam 504 is attached to the lower edge of the window and connects the four inner longitudinal beams 502; another inner inclined beam 504 connects the three inner longitudinal beams 502 with longer lengths; the inner transverse beam 503 is located below the inner inclined beams 504.

[0021] like Figure 3As shown, an external frame 6 for enhancing structural stability is welded to the outside of the hull. This frame is distributed on the outer surfaces of the side plates 2, the top of the top plate 3, and the stern plate 4, and includes the side frames, top crossbeams 601 and stern crossbeams 602, all cast from square tubing. There are two top crossbeams 601 and one stern crossbeam 602, both arranged laterally and parallel to the bottom beam 501. The side frames are divided into middle, bottom, front, rear, and top sections, with the middle section having the highest density, followed by the bottom.

[0022] The middle of the side outer frame adopts an inclined rectangular grid pattern, with the inclination angle the same as the lower edge of the window, and the uppermost part fitting against the lower edge of the window frame 201. Specifically, the middle of the side outer frame includes three main inclined beams 603 with an angle of θ1 and more than five secondary inclined beams 604 perpendicular to the angle of θ1. The secondary inclined beams 604 are arranged between the main inclined beams 603 and are staggered and welded. The main inclined beams 603 are the thickest beams in the outer frame 6, while the secondary inclined beams 604 are thinner. The bottom of the side outer frame adopts a rectangular grid pattern, including one horizontal main crossbeam 605 and three vertical main longitudinal beams 606. The main longitudinal beams 606 are arranged between the main crossbeams 605 and the main inclined beams 603. The bottom of the side outer frame also includes one horizontal secondary crossbeam 607 and three vertical secondary longitudinal beams 608. The secondary crossbeam 607 connects to the bottom edge of the side plate 2, and the secondary longitudinal beams 608 are arranged between the secondary crossbeams 607 and the main crossbeams 605. The side outer frame also features two long longitudinal beams 609, with the same thickness as the secondary longitudinal beam 608. These beams connect the top and bottom edges of the side panel 2 and are connected to the front and rear ends of the middle and bottom of the side outer frame. Specifically, the front and rear ends of the middle and bottom of the side outer frame refer to the ends of the main diagonal beam 603, the main crossbeam 605, and the secondary crossbeam 607. The forward-facing long longitudinal beam 609 runs straight through the top and bottom edges of the side panel 2, while the rearward-facing long longitudinal beam 609 is slightly bent before connecting to the top and bottom edges of the side panel 2 to avoid the track mounting holes and the door frame 301 installation position. Two top-surface crossbeams 601 on the top plate 3 connect to the long longitudinal beams 609 on both sides of the side panel 2. The top plate 3 also has corresponding crossbeam mounting grooves to accommodate the top-surface crossbeams 601 and restrict their forward and backward movement. The rear-surface crossbeam 602 on the tail plate 4 extends to the side panel 2 and connects to the rearward-facing long longitudinal beam 609. The top of the side frame includes a main diagonal beam 603, whose two ends are connected to two long longitudinal beams 609; a secondary longitudinal beam 608 is also provided between the connection point of the top horizontal beam 601 and the rear long longitudinal beam 609 and the top main diagonal beam 603. The front part 610 of the side frame is a right-angled rectangle, connected to the front long longitudinal beam 609. The rear part 620 of the side frame is triangular, connected to the rear long longitudinal beam 609.

[0023] The hyperbaric oxygen chamber of this invention can withstand higher internal air pressure, which has been tested to reach 1.5 atm, achieving higher chamber rigidity and high-pressure sealing stability.
