Description

Technical Field

[0001] The invention relates to an integrated fully flexible variable-distance 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, increase the effective diffusion distance (i.e., oxygen has a large penetrating power), increase tissue oxygen storage, improve tissue hypoxia, and contribute to the recovery of neurological and physical dysfunction. The micro-hyperbaric oxygen chamber injects purified air and high-purity oxygen into the cabin, where users can experience safe and efficient oxygen therapy. Especially for scenarios such as self-driving tours in the plateau, "mobile" medical stations, and plateau field operations, users need to use oxygen chambers to help relieve symptoms of altitude sickness and assist in the treatment of other diseases, but such scenarios place higher demands on the portability of oxygen chambers.

[0003] Flexible oxygen chambers are light, foldable, and easy to carry, making them more suitable for the above scenarios. However, most of the brackets used in existing flexible oxygen chambers are rigid brackets, which take a long time to assemble and build before use, and the rigid materials are heavy, which affects the safety and portability of the product in emergency scenarios. Some patents have proposed the use of flexible air columns as support structures to reduce product weight and improve product portability. The shape and structure of the air columns are also important factors affecting their usability.

[0004] The existing technology uses a flexible airtight membrane as the inner liner and an Oxford cloth as the outer cover. After inflation, a circular tubular gas column bracket is formed. Multiple tubular brackets are connected to each other to form a stable support structure, and the bracket is airtightly connected to the cabin. The disadvantages of the circular tubular bracket are: ① When the bracket lands, it is in line contact with the ground, and the same position is always stressed and worn during use; ② The diameter is large. On the one hand, the cabin is raised from the bottom, which may cause the cabin to leave the ground, and the stability is poor during use. In addition, the cabin material bears the gravity of the internal personnel instead of the ground force, which causes greater damage to the cabin; on the other hand, it increases the overall volume of the oxygen cabin. Summary of the invention

[0005] In response to the above technical problems, the present invention 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, thereby avoiding stress concentration, improving the stability of the frame during use, and at the same time increasing the service life of the product.

[0006] To achieve the above object, the present invention adopts the following technical solutions: An integrated fully flexible variable-gauge three-dimensional inflatable air rib frame, comprising: 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.

[0007] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame, preferably, the bottom support plate and the main body of the air rib support frame are made of composite spacing materials, and the sides are welded and sealed with a single layer of airtight material to form an airtight cavity.

[0008] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame, preferably, the composite spacer material includes weft-knitted spacer fabric, warp-knitted spacer fabric or woven spacer fabric, and the single-layer airtight material includes TPU, PVC, rubber or silicone mesh cloth.

[0009] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame, the surface of the composite spacer material is coated with an airtight layer, and preferably, a wear-resistant treatment agent is added to the airtight layer.

[0010] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame, preferably, the composite spacer material includes 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.

[0011] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame, preferably, the composite spacing 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 spacing 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.

[0012] The one-piece fully flexible variable-gauge three-dimensional inflatable air rib frame, preferably, the composite spacing material of the bottom support plate adopts a large-gauge plane 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.

[0013] 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 in contact with the ground, and a wear-resistant agent is added to the airtight layer.

[0014] A second aspect of the present invention provides a portable oxygen chamber, comprising an oxygen chamber body, wherein the oxygen chamber body 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.

[0015] The portable oxygen chamber is preferably provided with a transparent window on the cover, and a hatch is provided on the front side of the oxygen chamber body for the user to enter and can be opened and closed.

[0016] The present invention adopts the above technical solution, which has the following advantages: 1. The variable-spacing three-dimensional inflatable structure air rib frame of the present invention 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.

[0017] 2. The variable-gauge three-dimensional inflatable structure air rib frame of the present invention is in surface contact with the ground, which avoids the concentration of stress points and evenly disperses the wear on the bottom surface. At the same time, anti-cut and wear-resistant materials are selected as the bottom surface material to contact the ground, thereby improving the service life of the product.

[0018] 3. The variable-distance three-dimensional inflatable structure of the present invention is thinner than the cylindrical air column, which effectively improves the problem of lifting the cabin off the ground.

[0019] 4. Existing gas column support frames usually use a split design with a pasted structure and multiple inflation valves, which require multiple inflations to enable the entire structure to play a supporting role. This patent connects all parts of the oxygen cabin frame structure through welding technology, and can complete the inflation of the entire frame structure at one time, thereby improving the use efficiency.

DETAILED DESCRIPTION

[0024] The existing rigid bracket takes a long time to build and is heavy, which makes it inconvenient to carry and cannot be quickly built 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 easy to wear due to concentrated force. On the other hand, in order to ensure its rigidity and strength, the diameter of the gas column is ≥8cm, resulting in the bottom of the cabin suspended off the ground. The gravity of the people inside is borne by the cabin material, which can easily cause deformation of the cabin and cause great damage to the cabin.

[0025] Based on the above technical problems, the present invention 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, thereby reducing product weight, improving product portability and practicality, and expanding its application field.

[0026] like Figure 3 As shown, the integrated fully flexible variable-gauge three-dimensional inflatable air rib frame involved in the present invention 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 with each other, 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.

[0027] Specifically, the main body of the bottom support plate 2 and the air rib support frame 1 is made of composite spacer material, which includes weft-knitted spacer fabric, warp-knitted spacer fabric and woven spacer fabric as fabric reinforcement, and the outer layer is coated with an airtight layer (including but not limited to TPU, PVC, rubber, silicone) to ensure its airtightness and pressure bearing capacity, and the side is welded and sealed with a single layer of airtight material (including but not limited to TPU, PVC, rubber, silicone mesh cloth) to form an airtight cavity. Among them, the composite spacer material is composed of upper and lower surface layers and spacer wires, and the spacer wires are perpendicular to the upper and lower surface layers and connect the upper and lower surface layers; the thickness of the composite spacer material can be changed by changing the length of the spacer wire and the distance between the upper and lower surface layers, thereby changing the spacing of the three-dimensional inflatable structure.

[0028] Furthermore, the air rib support frame 1 preferably has a small-gauge three-dimensional structure (composite spacer material) with a spacing distance of 1.5cm~4.5cm, and the spacer wires are preferably high-strength and low-elastic multifilaments (including but not limited to 150~300D polyester multifilaments) 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 distance of 5~10cm, and the spacer wires are preferably monofilaments with high modulus (including but not limited to polyester monofilaments, nylon monofilaments, polypropylene monofilaments), and the monofilaments are distributed in an X-shaped point shape, which has better warmth retention, shock resistance, sound absorption and sound insulation, etc., and can also isolate surface moisture. The lower surface layer is preferably high-performance fibers such as ultra-molecular weight polyethylene and aramid, and wear-resistant agents (including but not limited to quartz particles, 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.

[0029] like Figure 3 As described, the air rib support frame 1 surrounds the oxygen chamber body 3, and after being inflated, it 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 in the shape of a flat plate, and is airtightly connected to the bottom surface of the oxygen chamber body 3. Its rigidity after being inflated is used 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 use efficiency of the product.

[0030] Furthermore, the present invention also provides a portable oxygen chamber, including 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 is airtightly connected to the integrated fully flexible variable-gauge three-dimensional inflatable gas rib frame, and an airtight chamber is formed inside the oxygen chamber body 3. A hatch for users to enter and can be opened and closed is provided on the front side of the oxygen chamber body 3.

[0031] The technical solution of the present invention is described in detail below with reference to specific examples.

[0032] Example 1 The air rib frame prepared in this embodiment is designed for a single-person seated oxygen chamber.

[0033] Use 600D polyester multifilament as the yarn material of the upper and lower surface layers, and 240D polyester multifilament as the spacer yarn material to 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 obtaining the composite spacer material A required for the air rib support frame.

[0034] 600D polyester multifilament is used as the yarn material of the upper and lower surface layers, and 0.15mm diameter polyester monofilament is used as the spacer yarn material. The warp knitted spacer fabric with a weaving spacing of 5cm is made. The spacer yarn is distributed in an X-shaped dot pattern on the surface. The structure is as follows: Figure 2 As shown. A TPU coating is applied to the outer surface layer of the warp knitted spacer fabric to provide air tightness, and microcrystalline quartz is added to the coating of the lower surface (the surface in contact with the ground) as a wear-resistant agent to improve the wear resistance of the coating, thereby obtaining the composite spacer material B required for the bottom support plate.

[0035] Material A is cut into strips with a width of 10 cm, and the edges are welded and sealed with TPU mesh cloth on all sides to form a long closed air cavity, namely the air rib support frame; Material B is cut into the same size as the bottom of the oxygen cabin, and the edges are welded and sealed with TPU mesh cloth on all sides to form a flat closed air cavity, namely the bottom support plate.

[0036] The frame is built according to the shape of the oxygen cabin body, and the air rib support frame 1 is arranged around the oxygen cabin body 3, and the bottom support plate 2 is arranged at the bottom of the oxygen cabin body 3. The air rib support frame and the air cavity of the bottom support plate are connected to form an integrated inflatable structure, that is, 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 filled with air, a three-dimensional structure is formed to provide support for the oxygen cabin body.

[0037] The present invention uses a variable-spacing three-dimensional inflatable structure to construct a fully flexible air rib frame, which is airtightly connected to a cabin body to build a fully flexible portable micro-pressure oxygen cabin, thereby reducing product weight, improving product portability and practicality, and expanding its application field.
