Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment, specifically to an external inflatable support column device for a soft oxygen chamber. Background Technology

[0002] With the widespread application of hyperbaric and hypobaric oxygen therapy, flexible oxygen chambers have become a commonly used auxiliary rehabilitation device in homes and primary healthcare institutions due to their portability, energy efficiency, and low cost. A typical flexible oxygen chamber structure consists of a chamber made of flexible material and an air source. Inflating the chamber with air allows it to expand and take shape, providing the user with a relatively sealed oxygen therapy environment.

[0003] However, in existing technologies, soft oxygen chambers often rely on the chamber's own air pressure to maintain their shape and stability after expansion. Since the chamber primarily depends on internal air pressure balance, fluctuations or leaks in internal pressure can easily cause the chamber to collapse, affecting the usability of the interior space. When users enter or exit the chamber or move around inside, the chamber is prone to tilting, swaying, or even collapsing entirely, hindering normal treatment and posing safety hazards. To ensure stability, some soft oxygen chambers often use rigid supports or external metal frames. While this enhances the chamber's support, it also increases the weight and size of the equipment, affecting portability and transportation. Furthermore, the complex assembly and disassembly of the supports hinders rapid deployment in clinical or home settings.

[0004] Therefore, there is an urgent need to design an external inflatable support column device for soft oxygen chambers, so as to maintain the shape of the chamber and improve the overall stability without increasing the overall weight of the equipment, and to adapt to different chamber sizes and application scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide an external inflatable support column device for a soft oxygen chamber. This device can provide uniform and reliable external support for the soft oxygen chamber without significantly increasing its weight, preventing the chamber from tilting or partially collapsing when the user enters or moves around. It also has the advantages of quick assembly and disassembly, easy storage and maintenance.

[0006] The technical solution adopted by this utility model to solve the above problems is: an external inflation support air column device for a soft oxygen chamber, including a chamber body, and several long strip-shaped support structures are detachably connected to the outer edge of the chamber body. The support structure includes a fixed outer jacket and an airbag disposed inside the fixed outer jacket. The airbag is wound around the fixed outer jacket to form multiple layers, and the fixed outer jacket is provided with an air nozzle communicating with the internal airbag.

[0007] Preferably, the support structure is connected and fixed to the cabin body via a zipper structure, the zipper structure comprising two sets of chain straps and zipper heads disposed on the outer side of the fixed outer jacket and the outer surface of the cabin body, respectively.

[0008] Preferably, the support structure is provided with a flexible conduit, and the airbag is spirally wrapped around the outside of the conduit.

[0009] Preferably, the support structure is composed of several support units connected end to end by a docking structure.

[0010] Preferably, the docking structure includes a magnetic suction element disposed at the end of the fixed outer sleeve and plugs and sockets disposed at both ends of the conduit and adapted for insertion.

[0011] Preferably, the plug has a sealing ring on its outer side, and the sealing ring fits tightly against the inner wall of the socket.

[0012] Preferably, the outer surface of the fixed outer jacket is provided with an anti-slip raised structure.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This invention effectively enhances the shape retention and lateral stability of the soft oxygen chamber by incorporating a detachable inflatable support structure (air column) on its exterior, without significantly increasing the overall weight of the equipment. By spirally winding the airbags into a multi-layered structure along the fixed outer casing, high support strength is maintained even under insufficient air pressure, significantly improving the reliability of the device. The flexible conduit design ensures the central stability of the airbag winding, contributing to the formation of a regularly shaped, evenly pressure-distributed air column. A zipper structure allows for quick disassembly from the chamber, enhancing the device's adaptability. The modular support unit design supports flexible assembly and combination according to chamber dimensions, facilitating maintenance and replacement. The synergistic effect of magnetic docking and plug / socket sealing structures further improves the continuity of the air path and the strength of the structural connections. Rubber granule anti-slip protrusions on the outer surface enhance the stability of the device during use. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] Example:

[0022] See Figures 1-4 This embodiment relates to an external inflatable support column device for a soft oxygen chamber, specifically used in homes or primary healthcare facilities to provide stable support for the soft oxygen chamber and prevent the chamber 11 from tilting or partially collapsing when the user moves inside. The device specifically includes a chamber 11, with several elongated support structures 12 detachably connected to its outer edges. Each support structure 12 includes a fixed outer sleeve 13 and airbags 14 disposed within the fixed outer sleeve 13. The airbags 14 are wound around the fixed outer sleeve 13 in multiple layers, and the fixed outer sleeve 13 is provided with air nozzles 15 communicating with the internal airbags 14.

[0023] Specifically, in this embodiment, the fixing jacket 13 is made of a long strip of flexible material such as TPU, and has an inner cavity 16 along its long axis. The airbag 14 is located inside the fixing jacket 13 and can be made of flexible material such as rubber, and is spirally wound around the fixing jacket 13 at least 3 to 5 times. The air nozzle 15 is disposed on the side wall of the fixing jacket 13 and is connected to the airbag 14 for connecting an external inflation pump. Compared with the traditional use of rigid brackets or external metal frames to support the cabin 11, this device uses the airbag 14 as support, which is lighter and easier to pack and store with the cabin 11 after deflation. In addition, compared with a single layer of airbag 14 directly filling the inner cavity 16 of the fixing jacket 13, the airbag 14 in this embodiment adopts a multi-layered design with each layer of airbag 14 overlapping and supporting each other, which can have high structural support strength even when not fully inflated. The multi-layered structure can also form a uniform pressure gradient, reduce local stress concentration, improve the durability of the airbag 14 and the service life of the device. This device can maintain the shape of the cabin 11 and improve overall stability without increasing the overall weight of the equipment, making it easy to carry and transport.

[0024] The support structure 12 is connected and fixed to the cabin 11 via a zipper structure 17. The zipper structure 17 includes two sets of chain straps 18 and zipper heads 19 disposed on the outer side of the fixed outer sleeve 13 and the outer surface of the cabin 11, respectively. Traditional external metal brackets require multiple bolts or straps for fixation, while in this embodiment, the entire support structure 12 can be fixed or removed using only one zipper head 19, shortening the installation time and making it convenient for users to disassemble and replace at any time.

[0025] A flexible conduit 21 is inserted into the support structure 12. The airbag 14 is spirally wound around the outside of the conduit 21, and one end of the airbag 14 is fixed by bonding to the outer surface of the conduit 21. Because the bonding restricts the radial freedom of the airbag 14, the airbag 14 can expand axially from the outer surface of the conduit 21 without producing a radial bulge when inflated. The gas pressure can only force the airbag 14 to extend axially along the conduit 21, forming an upright spiral support column. In production, the flexible conduit 21 is first inserted into the inner cavity 16 of the fixing sleeve 13. Then, the pre-cut airbag 14 film is tightly spirally wound around the conduit 21 and glued at the starting loop. After winding to the end, the last loop is heat-sealed at the contact point with the inner wall of the fixing sleeve 13. Afterward, holes are drilled at corresponding positions on the side wall of the fixing sleeve 13 to install the air nozzle 15. The air nozzle 15 is connected to the airbag 14, thus completing the overall assembly.

[0026] To accommodate flexible oxygen chambers of different lengths and specifications, in this embodiment, the complete support structure 12 is divided into several support units 22 of equal length. Each support unit 22 is connected end-to-end along the axial direction of the fixed outer casing 13, and rapid assembly is achieved through a docking structure 23. In this way, the number of support units 22 can be flexibly increased or decreased according to the length of the edges of the oxygen chamber body 11, satisfying both the full-length support requirements of large-space chambers 11 and the needs of shorter chambers 11. Furthermore, the support structure 12 adopts a modular unit structure design, which is easy to manufacture, inspect, and replace individually, greatly reducing maintenance costs.

[0027] The docking structure 23 includes a magnetic suction member 24 disposed at the end of the fixed outer sleeve 13 and a plug 25 and a socket 26 respectively disposed at both ends of the conduit 21 and adapted for insertion. When assembling the support unit 22, the plug 25 and the socket 26 at the docking point are first plugged into each other. After the connection is completed, the fixed outer sleeves 13 are attracted together by the magnetic suction member 24, which improves the integrity of the support structure 12 after docking.

[0028] A sealing ring 27 is provided on the outer side of the plug 25, and the sealing ring 27 fits tightly against the inner wall of the socket 26. The sealing ring 27 is located in a groove on the outer wall of the middle section of the plug 25, and the outer diameter of the ring is slightly larger than the inner diameter of the socket 26. When the plug 25 is inserted into the socket 26, the sealing ring 27 is immediately compressed and fits tightly against the inner wall of the socket 26, forming a seal. The compressed ring generates an elastic lateral thrust on the inner wall of the socket 26, creating a preloaded clamping force at the joint between the plug 25 and the socket 26, which significantly improves the pull-out resistance of the support unit 22 during docking. When the air column is impacted, this clamping force can effectively resist the impact and reduce the risk of accidental separation between the support units 22.

[0029] The outer surface of the fixed outer jacket 13 is provided with an anti-slip raised structure 28. The raised structure 28 is made of several natural or synthetic rubber microparticles with a diameter of 0.5–1 mm, which are uniformly adhered to the surface of the fixed outer jacket 13 by spraying or applying adhesive. The fixed outer jacket 13 can maintain a stable fit with the ground through the anti-slip particles, providing good grip and making it difficult for the support structure 12 to slide on the smooth surface, thereby improving the stability of the cabin 11 in use.

[0030] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
