Description

Technical Field

[0001] The utility model relates to an integrated fully flexible variable-spacing three-dimensional inflatable gas rib frame and a portable oxygen chamber, belonging to the technical field of medical equipment. Background Art

[0002] A high-pressure environment can increase the oxygen partial pressure gradient between alveoli, blood, and tissue cells, increasing the effective diffusion distance (i.e., greater oxygen penetration), improving tissue oxygen storage, and improving tissue hypoxia, thereby aiding the recovery of neurological and physical dysfunction. A micro-hyperbaric oxygen chamber pumps purified air and high-purity oxygen into the chamber, allowing users to experience safe and efficient oxygen therapy. Oxygen chambers are particularly useful for scenarios such as high-altitude self-drive tours, mobile medical stations, and field work in the plateau to alleviate altitude sickness symptoms and assist in the treatment of other conditions. However, these scenarios place higher demands on the chamber's portability.

[0003] Flexible oxygen chambers are lightweight, foldable, and easy to carry, making them particularly suitable for these scenarios. However, existing flexible oxygen chambers mostly use rigid supports, which require a long time to assemble before use. Furthermore, the rigid materials are heavy, compromising the product's safety and portability in emergency situations. Some patents have proposed the use of flexible gas columns as support structures to reduce product weight and improve portability. The shape and structure of the gas columns are also important factors affecting their usability.

[0004] Existing technology uses a flexible airtight membrane as the inner liner and an Oxford cloth outer shell. After inflation, these air-filled tubular air columns are formed. Multiple tubular columns are interconnected to form a stable support structure, which is then airtightly connected to the cabin. The disadvantages of the tubular columns are: 1) When the columns are placed on the ground, they are in line contact with the ground, so the same position is always subjected to force and wear during use; 2) their large diameter raises the cabin from the bottom, potentially lifting it off the ground and causing poor stability during use. Furthermore, the cabin material bears the weight of the occupants rather than the ground, causing significant damage to the cabin; and 3) they increase the overall volume of the oxygen chamber. Utility Model Content

[0005] In response to the above technical problems, the utility model provides an integrated, fully flexible, variable-spacing three-dimensional inflatable air rib frame and a portable oxygen chamber. The air rib frame uses a variable-spacing three-dimensional inflatable structure, which consists of an air rib support frame and a bottom support. It has a small thickness and a flat bottom surface that is in surface contact with the ground, avoiding stress concentration, improving the stability of the frame during use, and at the same time increasing the service life of the product.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An integrated fully flexible variable-gauge three-dimensional inflatable gas rib frame, comprising:

[0008] A bottom support plate and an air rib support frame symmetrically arranged on both sides of the bottom support plate, wherein the bottom support plate and the air rib support frame are both air-filled air cavities and are interconnected, the air rib support frame is an annular structure, and the longitudinal cross-section of the air rib support frame is rectangular or square.

[0009] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame preferably has the bottom support plate and the main body of the air rib support frame made of composite spacer material, and the sides are welded and sealed with a single layer of airtight material to form an airtight cavity.

[0010] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame preferably comprises: a weft-knitted spacer fabric, a warp-knitted spacer fabric or a woven spacer fabric; and the single-layer airtight material comprises TPU, PVC, rubber or silicone mesh cloth.

[0011] The integrated fully flexible variable-gauge three-dimensional inflatable air rib frame has an airtight layer coated on the surface of the composite spacer material. Preferably, a wear-resistant treatment agent is added to the airtight layer.

[0012] The integrated fully flexible variable-gauge three-dimensional inflatable air rib frame preferably comprises an upper surface layer, a spacer wire and a lower surface layer arranged in sequence from top to bottom, and the spacer wire is perpendicular to the upper surface layer and the lower surface layer, and connects the upper surface layer and the lower surface layer.

[0013] The integrated fully flexible variable-gauge three-dimensional inflatable air rib frame, preferably, the composite spacer material of the air rib support frame adopts a small-gauge three-dimensional structure with a spacing distance of 1.5cm~4.5cm, and the spacer wire of the air rib support frame adopts high-strength and low-elasticity multifilament, and the multifilament is arranged in parallel in a straight line.

[0014] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame preferably adopts a large-gauge flat three-dimensional structure with a spacing distance of 5 to 10 cm, and the spacing wire of the bottom support plate adopts a single wire, and the single wire is distributed in an X-shaped point shape.

[0015] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame is preferably provided with an airtight layer coated on the surface of the composite spacer material of the bottom support plate that contacts the ground, and a wear-resistant agent is added to the airtight layer.

[0016] The second aspect of the present invention provides a portable oxygen chamber, including an oxygen chamber body, which is composed of a skin and an integrated fully flexible variable-gauge three-dimensional inflatable air rib frame as described above. The skin is airtightly connected to the integrated fully flexible variable-gauge three-dimensional inflatable air rib frame, and an airtight cabin is formed inside the oxygen chamber body.

[0017] The portable oxygen chamber preferably has a transparent window on the cover, and a hatch on the front side of the oxygen chamber body for users to enter and which can be opened and closed.

[0018] The utility model has the following advantages due to the adoption of the above technical solution:

[0019] 1. The variable-spacing three-dimensional inflatable structure air rib frame of the utility model is in surface contact with the ground. Compared with the circular tubular bracket, it has better stability after inflation and can effectively prevent the oxygen cabin from tipping over and rolling.

[0020] 2. The variable-gauge three-dimensional inflatable structure air rib frame of the utility model is in surface contact with the ground, which avoids the concentration of force points and evenly distributes the wear on the bottom surface. At the same time, anti-cut and wear-resistant materials are used as the bottom surface material for contact with the ground, thereby improving the service life of the product.

[0021] 3. The variable-spacing three-dimensional inflatable structure of the present invention is thinner than the circular tubular air column, which effectively improves the problem of lifting the cabin off the ground.

[0022] 4. Existing gas column support frames usually use a split-structure design with adhesive bonding and multiple inflation valves, requiring multiple inflations to fully support the entire structure. This patented design connects all parts of the oxygen chamber frame through welding, allowing the entire frame structure to be inflated in one go, improving efficiency.

[0028] To make the purpose, technical solutions, and advantages of the present invention more clear, the following is a clear and complete description of the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0029] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the usual meanings understood by persons of ordinary skill in the field to which this utility model belongs. The words "first", "second", "third", "fourth" and similar terms used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0030] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inner side," "outer side," "lower," "upper," etc. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

[0031] The existing rigid bracket takes a long time to set up and is heavy, making it inconvenient to carry and unable to be quickly set up and deployed in an emergency. The existing flexible bracket is a tubular gas column bracket. On the one hand, the bracket is in line contact with the ground, the bracket has poor stability and is prone to wear due to concentrated force. On the other hand, to ensure its rigidity and strength, the diameter of the gas column is ≥8cm, causing the bottom of the cabin to be suspended off the ground. The gravity of the people inside is borne by the cabin material, which can easily cause the cabin to deform and cause great damage to the cabin.

[0032] Based on the above technical problems, the utility model provides an integrated fully flexible variable-spacing three-dimensional inflatable air rib frame and a portable oxygen chamber, which uses a variable-spacing three-dimensional inflatable structure to construct a fully flexible air rib frame, which is airtightly connected to the cabin body to build a fully flexible portable micro-pressure oxygen chamber, reducing product weight, improving product portability and practicality, and expanding its application field.

[0033] like Figure 3As shown, the integrated fully flexible variable-gauge three-dimensional inflatable air rib frame involved in the utility model includes: a bottom support plate 2 and air rib support frames 1 symmetrically arranged on both sides of the bottom support plate 2, the bottom support plate 2 and the air rib support frame 1 are both inflatable air cavities and are interconnected, the air rib support frame 1 is an annular structure connected end to end, and the longitudinal cross-section of the air rib support frame 1 is rectangular or square.

[0034] Specifically, the main body of the bottom support plate 2 and the air rib support frame 1 is made of a composite spacer material. The composite spacer material includes weft-knitted spacer fabric, warp-knitted spacer fabric, and woven spacer fabric as fabric reinforcement. The outer layer is coated with an airtight layer (including but not limited to TPU, PVC, rubber, and silicone) to ensure its airtightness and pressure-bearing capacity. The sides are welded and sealed with a single layer of airtight material (including but not limited to TPU, PVC, rubber, and silicone mesh cloth) to form an airtight cavity. The composite spacer material consists of upper and lower surface layers and spacer wires. The spacer wires are perpendicular to and connect the upper and lower surface layers. By changing the length of the spacer wires and the distance between the upper and lower surface layers, the thickness of the composite spacer material can be adjusted, thereby changing the spacing of the three-dimensional inflatable structure.

[0035] Furthermore, the air rib support frame 1 is preferably a small-gauge three-dimensional structure (composite spacer material) with a spacing of 1.5cm~4.5cm, and the spacer wire is preferably a high-strength low-elasticity multifilament (including but not limited to 150~300D polyester multifilament) arranged in parallel in a straight line, so that the air rib support frame 1 can more easily adapt to the curvature of the oxygen cabin body 3; the bottom support plate 2 is preferably a large-gauge planar three-dimensional structure with a spacing of 5~10cm, and the spacer wire is preferably a monofilament with a high modulus (including but not limited to polyester monofilament, nylon monofilament, polypropylene monofilament), and the monofilament is distributed in an X-shaped point shape, with better warmth retention, shock resistance, sound absorption and sound insulation, etc., and can also isolate surface moisture. The lower surface layer is preferably made of high-performance fibers such as ultra-molecular-weight polyethylene and aramid. At the same time, wear-resistant agents (including but not limited to quartz particles and alumina) are added to the airtight layer for treatment to improve its wear resistance and anti-cut and anti-puncture properties to prevent damage during outdoor use.

[0036] like Figure 3 As described, the air rib support frame 1 surrounds the oxygen chamber body 3 and, after being inflated, serves as a support structure to prevent the top of the oxygen chamber body 3 from collapsing when not inflated, thereby improving the structural stability during use; the bottom support plate 2 is flat and airtightly connected to the bottom surface of the oxygen chamber body 3. Its rigidity after inflation is utilized to prevent excessive changes in the curvature of the bottom surface of the oxygen chamber body 3, thereby improving the flatness of the internal space and the overall stability of the oxygen chamber body 3, and preventing tipping and rolling. The air rib support frame 1 is connected to the air cavity of the bottom support plate 2 through a welding process to form an integrated structure, which can complete the inflation of the entire frame structure at one time, thereby improving the efficiency of product use.

[0037] Furthermore, the present invention provides a portable oxygen chamber, comprising an oxygen chamber body 3, which is composed of a skin and an integrated fully flexible variable-gauge three-dimensional inflatable gas rib frame. The skin and the integrated fully flexible variable-gauge three-dimensional inflatable gas rib frame are airtightly connected to form an airtight chamber inside the oxygen chamber body 3. A hatch is provided on the front side of the oxygen chamber body 3 for the user to enter and can be opened and closed.

[0038] The technical solution of the present utility model is described in detail below with reference to specific examples.

[0039] Example 1

[0040] The air rib frame prepared in this embodiment is designed for a single-person seated oxygen cabin.

[0041] Use 600D polyester multifilament as the yarn material of the upper and lower surface layers, 240D polyester multifilament as the spacer yarn material, and weave a warp-knitted spacer fabric with a spacing of 3 cm. The spacer yarns are arranged in parallel in a straight line on the surface. The structure is as follows: Figure 1 As shown, a TPU coating is applied to the outer surface layer of the warp-knitted spacer fabric to provide air tightness, thereby producing the composite spacer material A required for the air rib support frame.

[0042] Use 600D polyester multifilament as the yarn material of the upper and lower surface layers, and 0.15mm diameter polyester monofilament as the spacer yarn material to weave a warp knitted spacer fabric with a spacing of 5cm. The spacer yarns are distributed in an X-shaped dot pattern on the surface. The structure is as follows: Figure 2 As shown in the figure, a TPU coating is applied to the outer surface layer of the warp-knitted spacer fabric to provide airtightness, and microcrystalline quartz is added to the coating on the lower surface (the surface in contact with the ground) as a wear-resistant agent to improve the wear resistance of the coating, thereby producing the composite spacer material B required for the bottom support plate.

[0043] Cut material A into strips with a width of 10 cm, and weld and seal the edges with TPU mesh cloth to form a long closed air cavity, namely the air rib support frame; cut material B into the same size as the bottom of the oxygen chamber, and weld and seal the edges with TPU mesh cloth to form a flat closed air cavity, namely the bottom support plate.

[0044] Build a frame according to the shape of the oxygen cabin body, set the air rib support frame 1 around the oxygen cabin body 3, set the bottom support plate 2 at the bottom of the oxygen cabin body 3, and connect the air cavities of the air rib support frame and the bottom support plate to form an integrated inflatable structure, namely the air rib frame. The structure is as follows: Figure 3 When the air rib frame is not inflated, the fully flexible structure is easy to fold and store; when the air rib frame is inflated, it forms a three-dimensional structure, providing support for the oxygen cabin body.

[0045] The utility model uses a variable-spacing three-dimensional inflatable structure to construct a fully flexible gas rib frame, which is airtightly connected to the cabin body to build a fully flexible portable micro-pressure oxygen chamber, thereby reducing product weight, improving product portability and practicality, and expanding its application field.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
