Technical Field
[0001] This invention relates to the field of home medical device technology, specifically to a portable modular oxygen therapy device. Background Technology
[0002] Oxygen concentrators are crucial equipment for long-term oxygen therapy for patients with hypoxic diseases such as chronic obstructive pulmonary disease and pulmonary heart disease. They are widely used in homes, outdoors, offices, and other public places, not only supporting patients' daily health care but also helping them integrate into normal social life. With the increasing aging population and rising health awareness among residents, patients' needs for oxygen concentrators have expanded from basic therapeutic functions to higher expectations for portability, intelligence, and humanistic care.
[0003] Currently, most common oxygen concentrators focus on functionality and have significant shortcomings: insufficient portability—traditional home oxygen concentrators are large and heavy, requiring fixed locations for outdoor use and failing to meet patients' mobility needs for travel and social interaction; complex operation procedures, resulting in high learning costs for elderly users; furthermore, existing oxygen concentrators are mostly single, fixed structures with low functional module integration, making it difficult to adjust according to user habits and failing to provide patients with a more personalized and flexible healthcare experience. Therefore, there is an urgent need for a portable, modular oxygen therapy device to address these issues. Summary of the Invention
[0004] The purpose of this invention is to provide a portable modular oxygen therapy device to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a portable modular oxygen therapy device, comprising an integrated oxygen generator with a hook and a breathing accessory with a connection port. The oxygen generator has an air inlet with a filter. The oxygen generator contains a compressor module and a molecular sieve module, as well as a retractable oxygen tube. The compressor module is configured to guide external gas into the air inlet, compress it, and then send it into the molecular sieve module. One end of the oxygen tube is connected to the air outlet of the molecular sieve module, and the other end is wound around the compressor module and extends to the outside of the oxygen generator. The compressor module and the molecular sieve module are coaxially arranged and rotatably installed in the oxygen generator for releasing or retracting the oxygen tube. The extended end of the oxygen tube is provided with a connector for splicing with the connection port of the breathing accessory.
[0006] Preferably, the oxygen generator includes a segmented cylindrical structure, namely an upper cylindrical structure and a lower cylindrical structure. The hook is installed on the top of the upper cylindrical structure, and the air inlet is located on the top of the upper cylindrical structure. The compressor module is installed inside the upper cylindrical structure, and the molecular sieve module is installed inside the lower cylindrical structure.
[0007] Preferably, the oxygen generator is provided with a buckle, with the side of the buckle facing the oxygen generator defined as the inner side. The outer side of the buckle is provided with a teardrop-shaped opening, which has a circular deep groove and a semi-elliptical shallow groove. The semi-elliptical shallow groove and the circular deep groove are smoothly transitioned. The connector is snapped into the circular deep groove and tends to move out of the buckle when it is subjected to force and moves towards the semi-elliptical shallow groove.
[0008] Preferably, the connector is an annular structure with a central through hole and an H-shaped cross-section. The groove portion of the H-shaped annular structure has an elastic member facing the inner wall of the through hole. A protrusion is provided in the circular deep groove and away from the semi-elliptical shallow groove. The protrusion is configured such that when the connector is engaged in the circular deep groove, the protrusion penetrates into the central groove and squeezes the inner wall of the elastic member in the groove, causing it to deform in the direction of the through hole and blocking and closing the through hole.
[0009] Preferably, a trumpet-shaped elastic block is provided inside the oxygen generator at the inside of the buckle, with the smaller diameter end facing the inside of the buckle. The oxygen tube passes through the trumpet-shaped elastic block, which is configured to scrape off impurities on the outer surface of the oxygen tube when it is wound up.
[0010] Preferably, the oxygen generator has a receiving cavity, and one opening of the receiving cavity corresponds to the smaller end of the horn-shaped elastic block.
[0011] Preferably, the air inlet is provided with a filter structure, which includes a handle, a filter screen and a plug with a mounting cavity from top to bottom. The top and bottom of the plug are hollow structures, and the middle part is a mounting cavity for placing filter cotton. The top of the compressor module is provided with a receiving interface corresponding to the air inlet. The filter structure is configured to be inserted into the receiving interface along the air inlet until the filter screen fits into the opening of the air inlet.
[0012] Preferably, the outer side of the insert block is provided with multiple protrusions along the circumferential direction, and the corresponding receiving interface is provided with multiple channels. As the filter structure is inserted into the receiving interface along the air inlet, the protrusions are inserted into the channels, and the insert block engages with the receiving interface, so that the compressor module and the molecular sieve module are simultaneously controlled by the filter structure to rotate synchronously.
[0013] Preferably, a cover plate is provided between the handle and the filter screen, and the filter screen and the insert block are fixedly connected by a first connecting post. The handle and the cover plate are fixedly connected by a second connecting post. The second connecting post is inserted into the first connecting post, and the second connecting post is configured to extend and retract within the first connecting post within a preset range, so that the cover plate is attached to or detached from the filter screen.
[0014] Beneficial effects: The integrated long strip structure of this invention, combined with a multi-scenario wearing and fixing module, can be hung, held, or laid flat, making it suitable for use in various scenarios such as outdoors, office, and home. The teardrop-shaped opening in the buckle of this invention not only secures the oxygen tube connector but also allows for easy removal of the connector for subsequent splicing operations by squeezing and pushing upwards. Compared to conventional buckling and pulling operations, this is more convenient and reduces damage to the connector. Furthermore, the inner wall of the protrusion and elastic component, along with the connector's H-shaped annular structure, prevents the connector from detaching from the buckle unconventionally and automatically seals and opens the central through-hole, thus preventing contamination within the central through-hole. Compared to structures like sealing plugs, no insertion or removal operation is required, and it also minimizes the risk of exposed components entering the oxygen tube and causing contamination.
[0015] The present invention, through the design of the filter structure, not only facilitates the quick replacement of the filter cotton, but also controls the rotation of the compressor module to release or retract the oxygen tube. By optimizing the structural design and improving the adaptability to different scenarios, it takes into account both therapeutic functions and user experience, meets the oxygen therapy needs of patients in multiple scenarios, and helps them improve their quality of life.

[0018] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.
[0019] Example: A portable modular oxygen therapy device, such as Figures 1-2As shown, the device includes an integrated oxygen generator 1 with a hook 13 and a breathing accessory 2 with a connection port 21. The oxygen generator 1 has an air inlet 3 with a filter 92. Inside the oxygen generator 1 are a compressor module 4, a molecular sieve module 5, and a retractable oxygen tube 6. The compressor module 4 and the molecular sieve module 5 are connected via an airway. Oxygen and nitrogen separation is achieved using PSA pressure swing adsorption technology, providing a stable output of medical oxygen at a concentration of 93% ± 3%. The oxygen generator 1 also has a multi-layer PCB circuit board 8 integrating a main control chip, a sensor interface module, a power management module, and a Bluetooth communication module, which connects to the oil-free compressor 42 to coordinate the overall operation of the device. A pop-up battery 7 is located at the bottom of the oxygen generator 1. The pop-up battery 7 allows for quick replacement via a press-lock and pop-out mechanism, supporting direct charging via Type-C interface and charging while in use. A silicone anti-slip ring at the bottom ensures stability. The breathing accessory 2 includes two replaceable designs: a disposable mask and a silicone mouth and nose mask, both connected to the oxygen generator 1 via a quick-release connection port 21. The connector 61 of the air pipe 6 is adapted. During use, the compressor module 4 is configured to guide external gas into the air inlet 3, compress it, and then send it into the molecular sieve module 5. In this embodiment, the compressor module 4 includes a housing 41 and an oil-free compressor 42 located inside the housing 41. The molecular sieve module 5 also includes a housing 41 and an internal molecular sieve adsorption tower. The housing 41 of the compressor module 4 and the housing 41 of the molecular sieve module 5 are coaxially connected, and both housings 41 are rotatably installed inside the oxygen generator 1. One end of the oxygen tube 6 extends downwards and connects to the outlet of the molecular sieve module 5, while the other end is wrapped around the compressor module 4 and extends to the outside of the oxygen generator 1. The oxygen tube 6 can be released or retracted by rotating the casing 41 of the compressor module 4. Releasing the oxygen tube 6 allows the connector 61 of the oxygen tube 6 to connect to the breathing accessory 2. The hook 13 of the oxygen generator 1 can be attached to a backpack, trolley, or other carrier. The generator's dimensions are 55×56×223mm, and the outer casing is made of sound-insulating material, with an operating noise ≤40dB. (Reference) Figures 1-2 and Figure 9 As shown, in this embodiment, the oxygen generator 1 includes a segmented cylindrical structure, namely an upper cylinder structure and a lower cylinder structure. The hook 13 is installed on the top of the upper cylinder structure, and the air inlet 3 is located on the top of the upper cylinder structure. The compressor module 4 is installed inside the upper cylinder structure, and the molecular sieve module 5 is installed inside the lower cylinder structure. The integrated long strip structure is equipped with a multi-scenario wearing and fixing module, which can be hung, held or laid flat, and is suitable for use in multiple scenarios such as outdoor, office and home.
[0020] In one embodiment, reference Figures 3-5As shown, a filter structure 9 is provided at the air inlet 3, which includes a handle 91, a filter screen 92, and a plug 93 with a mounting cavity 95 from top to bottom. The top and bottom of the plug 93 are hollow structures, and the middle part is the mounting cavity 95 for placing filter cotton. The top of the cover 41 of the compressor module 4 is provided with a receiving interface 411 corresponding to the air inlet 3. The filter structure 9 is configured to be inserted into the receiving interface 411 along the air inlet 3 until the filter screen 92 fits with the opening of the air inlet 3. In use, the gas enters from the filter screen 92, passes through the filter cotton in the mounting cavity 95 for filtration, and then flows to the compressor through the receiving interface 411. When replacement is required, the filter structure 9 is pulled out, the filter cotton in the mounting cavity 95 is replaced, and then it is reinstalled. The operation is simple. A sealing rubber gasket or other structure can be set at the receiving interface 411 to make the filter structure 9 more stable. The modular design facilitates disassembly and maintenance, and can be replaced independently, reducing maintenance costs.
[0021] In one embodiment, reference Figures 4-5 As shown, multiple protrusions 96 are arranged circumferentially on the outer side of the insert block 93, and multiple grooves 412 are correspondingly provided at the receiving interface 411. The filter structure 9 is inserted into the receiving interface 411 along the air inlet 3, and the protrusions 96 are inserted into the grooves 412. The insert block 93 engages with the receiving interface 411, so that the cover 41 of the compressor module 4 is controlled to rotate synchronously with the filter structure 9. When in use, the insert block 93 is rotated by the handle 91, thereby synchronously driving the cover 41 to rotate, thereby removing the oxygen tube 6 wrapped around the cover 41. After use, the oxygen tube 6 can be wound up and recycled by rotating in the opposite direction. The operation is simple and especially suitable for the operation needs of the elderly.
[0022] In one embodiment, reference Figures 4-5 As shown, a cover plate 94 is provided between the handle 91 and the filter screen 92, and the filter screen 92 and the insert block 93 are fixedly connected by a first connecting post 97. The handle 91 and the cover plate 94 are fixedly connected by a second connecting post 98. The second connecting post 98 is inserted into the first connecting post 97 and is configured to extend and retract within the first connecting post 97 within a preset range, so that the cover plate 94 is attached to or detached from the filter screen 92. When not in use, by pressing down the handle 91, force is applied to the second connecting post 98, causing it to enter the first connecting post 97, thereby making the cover plate 94 fit against the filter screen 92 and cover its top. When in use, press the filter screen 92 and then pull up the handle 91 to separate the cover plate 94 from the filter screen 92. When in use, a shielding platform can be formed on the top of the filter screen 92 to prevent external structures from directly impacting the filter screen 92 and causing blockage or damage, or liquids from directly flowing into the filter screen 92, effectively protecting the filter screen 92 and its internal structure.
[0023] In one embodiment, reference Figure 1 and Figure 3As shown, a latch 10 is provided on the oxygen generator 1. The latch 10 connects the inside of the upper cylinder structure to the outside. The side of the latch 10 facing the oxygen generator 1 is defined as the inner side. (Refer to...) Figure 6 As shown, the buckle 10 has a teardrop-shaped opening on its outer side. The teardrop-shaped opening has a circular deep groove 101 and a semi-elliptical shallow groove 102, and the semi-elliptical shallow groove 102 and the circular deep groove 101 are smoothly transitioned. In the initial state, the connector 61 is snapped into the circular deep groove 101. When it is needed, the connector 61 is moved toward the semi-elliptical shallow groove 102 by squeezing it with a finger. At this time, the connector 61 will gradually move toward the direction of disengaging from the buckle 10 during the process of moving toward the semi-elliptical shallow groove 102. There is no need to remove the connector 61 by snapping or pulling. The operation is simple and convenient, and the connector 61 will not be damaged by operation. When the connector 61 is reset, it is inserted diagonally into the semi-elliptical shallow groove 102 and pushed down into the circular deep groove 101.
[0024] In one embodiment, reference Figure 8 As shown, the connector 61 is an annular structure with a central through hole 611 and an H-shaped cross-section. The groove 612 portion of the H-shaped annular structure has an elastic member facing the inner wall 613 of the through hole. A protrusion 103 is provided in the circular deep groove 101 and away from the semi-elliptical shallow groove 102. The protrusion 103 is configured such that when the connector 61 is engaged in the circular deep groove 101, the protrusion 103 penetrates into the central groove 612 and squeezes the inner wall 613 of the elastic member in the groove 612, causing it to deform towards the through hole and blocking and closing the through hole. The inner wall 613 can be away from the central through hole in its natural state. The recessed 611 direction keeps the inner wall 613 surface as far away from the central through hole 611 as possible. Through the action of the protrusion 103, the connector 61 can be prevented from disengaging from the circular deep groove 101 along the axis direction. At the same time, when the connector 61 is in the circular deep groove 101, the central through hole 611 in the middle of the connector 61 is automatically blocked to prevent contamination inside the central through hole 611 when not in use. When the connector 61 is disengaged from the buckle 10, the elastic force of the inner wall 613 of the elastic member automatically resets, thereby opening the central through hole 611 to facilitate connection with the breathing accessory 2.
[0025] In one embodiment, reference Figure 6 and Figure 7As shown, a trumpet-shaped elastic block 11 is provided inside the oxygen generator 1 at the inside of the buckle 10, with the smaller diameter end facing the inside of the buckle 10. The oxygen tube 6 passes through the trumpet-shaped elastic block 11. The trumpet-shaped elastic block 11 is configured to automatically scrape impurities on the outer surface of the oxygen tube 6 when winding up the oxygen tube 6, keeping the inside of the upper cylinder structure clean. In this embodiment, a receiving cavity 12 is provided inside the oxygen generator 1 at the buckle 10. One opening of the receiving cavity 12 corresponds to the smaller diameter end of the trumpet-shaped elastic block 11. The receiving cavity 12 can collect the impurities scraped from the oxygen tube 6. The buckle 10 and the receiving cavity 12 are detachably installed on the oxygen generator 1 for subsequent cleaning.
[0026] The embodiments of the present invention have been described in detail above with reference to the examples. However, the present invention is not limited to the above embodiments. For those skilled in the art, after learning the contents described in the present invention, several equivalent changes and substitutions can be made without departing from the principle of the present invention. These equivalent changes and substitutions should also be considered to fall within the protection scope of the present invention.
