Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an oxygen inhalation device for treating cluster headaches. Background Technology

[0002] Cluster headache is a primary headache disorder characterized by severe, unilateral periorbital or temporal pain, often accompanied by autonomic symptoms such as conjunctival congestion, lacrimation, and nasal congestion. The pain is extremely intense during attacks, exhibiting a pronounced periodicity and frequency, and is often described as suicidal headache. It is prevalent in specific age groups, and patients often experience significant restlessness due to the intense pain, significantly impacting their quality of life. Current treatments for cluster headache primarily focus on rapid relief during acute attacks and preventative interventions, but existing treatments have many limitations.

[0003] Specifically, regarding drug treatment, commonly used medications in the acute phase may cause adverse reactions, are unsuitable for some patients, and long-term use may lead to side effects. Prophylactic medications, on the other hand, have issues with unstable efficacy or require long-term use, making it difficult to meet the need for rapid relief during acute attacks. Clinical guidelines clearly recommend high-flow-rate, high-concentration oxygen therapy as a first-line treatment for acute attacks due to its rapid onset, high safety, and lack of drug dependence risk. However, traditional medical oxygen therapy typically relies on high-pressure oxygen cylinders or large oxygen concentrators. The former suffers from inconvenient storage and transportation and limited usage time, while the latter is bulky, consumes a lot of power, and requires continuous power, making it difficult to meet the immediate treatment needs of patients at home, while out and about, or in emergency situations at night.

[0004] Existing portable oxygen generators mostly employ small molecular sieve pressure swing adsorption (PSA) technology. While offering a degree of portability, they generally suffer from complex structures and reliance on multiple sets of solenoid valves and controllers for gas path switching. This results in low reliability, high energy consumption, and an inability to meet the high-concentration oxygen requirements of cluster headaches in terms of rapid response and oxygen supply stability. Furthermore, most devices separate purification and pressurization functions, necessitating the addition of an air pump or compression component, further increasing the equipment's size and cost.

[0005] Therefore, this invention proposes an oxygen inhalation device for treating cluster headaches, which achieves synergistic energy utilization through a linkage mechanism to improve the energy efficiency of the device; the amplification mechanism drives the periodic switching of the purification mechanism to reduce secondary energy conversion losses; and the reduced dependence on external power sources can reduce economic pressure and improve the sustainability of treatment. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides an oxygen inhalation device for treating cluster headaches. This device utilizes a linkage mechanism to achieve synergistic energy utilization, thereby improving the device's energy efficiency. An amplification mechanism drives the periodic switching of the purification mechanism, reducing secondary energy conversion losses. This reduces reliance on external power sources, lowers economic burden, and enhances the sustainability of treatment.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: An oxygen inhalation device for treating cluster headaches includes a housing and a controller. An air outlet pipe is connected to the top of the housing, and a breathing mask is connected to the end of the air outlet pipe away from the housing. The housing is provided with a purification mechanism, an amplification mechanism and a linkage mechanism. The purification mechanism is used to separate and purify oxygen from ambient air. The amplification mechanism is used to pressurize the oxygen output by the purification mechanism and output it to the breathing mask.

[0008] The linkage mechanism is used to convert the switching power of the amplification mechanism into the motion that drives the periodic switching of the purification mechanism, so that the switching cycle of the purification mechanism is synchronized with the gas supply cycle of the amplification mechanism, thereby realizing the switching of the adsorption and desorption processes of the purification mechanism.

[0009] The technical principles of the above solution are as follows:

[0010] Continuous oxygen supply is achieved by separating and alternately purifying oxygen from ambient air through a purification mechanism. The amplification mechanism pressurizes the purified oxygen before delivering it to the patient, ensuring the output pressure meets the requirements of the respiratory mask. A linkage mechanism converts the mechanical motion of the amplification mechanism into a power source, synchronously controlling the adsorption and desorption switching of the purification mechanism. This synchronizes the switching cycle of the purification mechanism with the gas supply cycle of the amplification mechanism, ensuring a continuous and stable oxygen output and reducing energy waste. No additional electronic control components or independent drive sources are required; the process switching is completed through internal mechanical linkage, resulting in a compact structure and reliable response.

[0011] The above approach has the following beneficial effects:

[0012] 1. This solution synchronizes the purification and gas supply cycles through a linkage mechanism, ensuring patients receive a continuous and stable high concentration of oxygen during use. Traditional oxygen therapy devices may experience fluctuations in oxygen concentration or intermittent insufficient supply due to a disconnect between purification and gas supply, affecting treatment efficacy. In this device, the linkage mechanism converts the motion of the amplification mechanism into the switching power of the purification mechanism, matching the adsorption and desorption processes with the gas supply rhythm. This avoids resource waste caused by over-purification and reduces the drop in oxygen concentration caused by under-purification, making it suitable for the high oxygen supply stability requirements of cluster headache attacks.

[0013] 2. This solution's linkage mechanism drives the purification mechanism to complete the periodic switching between adsorption and desorption states, reducing the use of external power output components. Traditional oxygen absorption devices often rely on multiple sensors, controllers, and other electronic components for periodic control, which not only increases equipment costs and the risk of failure but may also affect operational stability due to aging electronic components or environmental interference. In contrast, the mechanical linkage structure of this device has stronger environmental adaptability, achieving multi-functional collaboration with fewer components and reducing the failure rate during equipment use.

[0014] 3. This solution achieves synergistic energy utilization through a linkage mechanism, improving equipment energy efficiency; the amplification mechanism drives the cycle switching of the purification mechanism, reducing secondary energy conversion losses. In traditional devices, purification and gas supply often operate independently, requiring separate energy consumption, resulting in low overall energy efficiency. This device's design enables synergistic energy utilization internally, reducing dependence on external power sources. For patients requiring long-term or frequent oxygen therapy, this energy-saving design effectively reduces financial burden and enhances the sustainability of treatment.

[0015] Furthermore, the purification mechanism includes a first sieve cylinder and a second sieve cylinder detachably connected to the inner wall of the housing, and a first fan blade is rotatably fitted inside both the first sieve cylinder and the second sieve cylinder; the housing is provided with a transmission mechanism for driving the first fan blade to rotate and a conversion mechanism for driving the first fan blade to change direction.

[0016] Beneficial effects: By using a double sieve cylinder in conjunction with a steerable first fan blade, the adsorption and desorption processes can be switched; the transmission mechanism ensures that the first fan blades in the two sieve cylinders operate synchronously, while the conversion mechanism can periodically change the rotation direction of the fan blades, thereby alternating the working mode of the sieve cylinders, completing the regeneration and purification cycle of the molecular sieve, and improving the response speed and operational stability.

[0017] Furthermore, the transmission mechanism includes a bracket fixedly connected to the inner wall of the housing, a worm gear rotatably fitted on the bracket, and worm wheels symmetrically meshing on both sides of the worm gear; each worm wheel is coaxially fixedly connected to a rotating shaft, and each rotating shaft is fixedly connected to the first fan blade.

[0018] Beneficial effects: The transmission mechanism adopts a meshing structure of worm and symmetrical worm wheel, which can synchronously transmit a single input power to the two first blades, ensuring the stable operation of the first blades in the two screen cylinders. When the worm rotates, the two worm wheels rotate in opposite directions, realizing the adsorption and desorption functions.

[0019] Furthermore, the conversion mechanism includes a first bevel gear coaxially fixedly connected to the worm gear, a sliding shaft slidably fitted on the bracket, and second bevel gears symmetrically and coaxially fixedly connected to the outer wall of the sliding shaft, with each of the second bevel gears meshing with the first bevel gear; the housing also includes a drive mechanism for driving the sliding shaft to rotate and a sliding mechanism for driving the sliding shaft to slide.

[0020] Beneficial effects: By driving the second bevel gear to switch meshing positions on both sides of the first bevel gear through the sliding shaft, the rotation direction of the worm gear is periodically reversed, thereby driving the fan blades to rotate alternately in both directions, completing the switching between adsorption and desorption of the screen cylinder. The process timing can be controlled solely by mechanical sliding and gear meshing, improving the integration and operational stability of the device.

[0021] Furthermore, the drive mechanism includes a drive component, which is electrically connected to the controller. The drive component is slidably fitted onto the side wall of the housing, and the output shaft of the drive component is coaxially and fixedly connected to the sliding shaft.

[0022] Beneficial effects: By controlling the start, stop and operation status of the drive components through the controller, the sliding shaft obtains rotational power. Its sliding fit facilitates coordinated work with the sliding mechanism to achieve a compound motion of rotation and axial movement, providing a reliable driving force for the purification process cycle.

[0023] Furthermore, the sliding mechanism includes a telescopic member fixedly connected to the outer wall of the housing, and the controller is electrically connected to the telescopic member; a slide rod is fixedly connected to the output shaft of the telescopic member, and a connecting shaft is fixedly connected to the outer wall of the slide rod, with the end of the connecting shaft away from the slide rod being fixedly connected to the outer wall of the slide shaft.

[0024] Beneficial effects: The telescopic component drives the slide bar to move axially under the controller's command, thereby switching the position of the sliding shaft and realizing the conversion of the meshing state between the second bevel gear and the first bevel gear. This ensures the periodic alternation of the adsorption and desorption processes and improves operational reliability.

[0025] Furthermore, the amplification mechanism includes a second fan blade fixedly connected to the end of the sliding shaft away from the driving component. Both the first and second sieve cylinders are connected to an output pipe and an input pipe. The input pipes are all connected to the outside of the housing, and the output pipes are all connected to the air outlet pipe. The second fan blade is rotatably fitted inside the air outlet pipe.

[0026] Beneficial effects: By utilizing the rotation of the sliding shaft to drive the second fan blade, the purified oxygen is instantly pressurized in the output pipe and delivered to the outlet pipe, reducing the need for a separate air pump or additional transmission components. Simultaneously, it shares a power source with the purification mechanism, achieving efficient energy utilization, further simplifying the overall structure, and enhancing integration and operational stability.

[0027] Furthermore, the linkage mechanism includes several gates that rotate and engage with the inner walls of the output pipe and the input pipe, each gate being fixedly connected with an opening and closing gear; a rack is fixedly connected to the outer wall of the slide rod, and the opening and closing gears mesh with the rack.

[0028] Beneficial effects: By meshing the rack on the slide bar with the opening and closing gears of each gate, the linear displacement of the slide bar is converted into the rotational action of the gate, realizing the opening and closing of the valves of the input and output pipes. This ensures that when one screen cylinder adsorbs and supplies oxygen, the other screen cylinder is reliably isolated and desorbed for regeneration, thereby improving oxygen purification efficiency and operational stability.

[0029] Furthermore, both the bottom of the first and second sieve cylinders can be detachably connected to a collection box.

[0030] Beneficial effects: During the desorption stage, the first blade reverses to generate a reverse airflow, purging the molecular sieve to achieve self-cleaning and effectively removing adsorbed residues and dust. The detachable collection box is used to collect impurities and particles that fall off during the cleaning process. This design not only improves the cleanliness and oxygen purity of the device but also facilitates regular maintenance by users, enhancing the long-term reliability and safety of the equipment.

[0031] Furthermore, the surfaces of both the first and second blades are coated with molecular sieve adsorption material.

[0032] Beneficial effects: Molecular sieve adsorbent materials enable them to perform both gas agitation and auxiliary adsorption functions during rotation, increasing the adsorption contact area and improving oxygen purification efficiency; they participate in the adsorption process while simultaneously achieving pressurization or process switching, resulting in high integration, which helps simplify the structure and improve energy utilization efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following detailed description illustrates the specific implementation method:

[0042] Example 1:

[0043] As attached Figures 1-4 As shown: An oxygen inhalation device for treating cluster headaches includes a housing 1 and a controller. The top of the housing 1 is connected to an air outlet pipe 2, and the end of the air outlet pipe 2 away from the housing 1 is connected to a breathing mask 3. The housing 1 is equipped with a purification mechanism, an amplification mechanism and a linkage mechanism. The purification mechanism is used to separate and purify oxygen from ambient air. The amplification mechanism is used to pressurize the oxygen output from the purification mechanism and output it to the breathing mask 3.

[0044] The linkage mechanism is used to convert the switching power of the amplification mechanism into the motion that drives the periodic switching of the purification mechanism, so that the switching cycle of the purification mechanism is synchronized with the gas supply cycle of the amplification mechanism, thereby realizing the switching of the adsorption and desorption processes of the purification mechanism.

[0045] Combination Figure 2 As shown, the purification mechanism includes a first sieve cylinder 4 and a second sieve cylinder 5 detachably connected to the inner wall of the housing 1. A first fan blade 6 is rotatably fitted inside both the first sieve cylinder 4 and the second sieve cylinder 5. The housing 1 is provided with a transmission mechanism for driving the first fan blade 6 to rotate and a conversion mechanism for driving the first fan blade 6 to turn. In this embodiment, both the first sieve cylinder 4 and the second sieve cylinder 5 are filled with molecular sieves.

[0046] The transmission mechanism includes a bracket 7 bolted to the inner wall of the housing 1. A worm 8 is rotatably fitted on the bracket 7, and worm wheels 9 are symmetrically meshed on both sides of the worm 8. Each worm wheel 9 is coaxially keyed to a rotating shaft 10, and each rotating shaft 10 is screwed to the first blade 6. In this embodiment, when the helical groove on the outer surface of the worm 8 meshes with the worm wheels 9, it will produce a spiraling effect with the worm wheels 9 on both sides respectively. Therefore, when the worm 8 rotates, the helical groove and the worm wheels 9 on both sides continuously engage with each other, thereby causing the worm wheels 9 to rotate in opposite directions.

[0047] Combination Figure 3 As shown, the conversion mechanism includes a first bevel gear 11 coaxially keyed to the worm gear 8, a sliding shaft 12 slidably fitted on the bracket 7, and second bevel gears 13 symmetrically coaxially keyed to the outer wall of the sliding shaft 12. Both second bevel gears 13 mesh with the first bevel gear 11. The housing 1 also includes a drive mechanism for rotating the sliding shaft 12 and a sliding mechanism for sliding the sliding shaft 12. In this embodiment, when the sliding shaft 12 is in different positions, the second bevel gears 13 can selectively mesh with the first bevel gear 11, changing the power transmission path. This allows the symmetrical second bevel gears 13 to mesh with the first bevel gear 11 respectively, resulting in different directions of rotation for the first bevel gear 11, thereby achieving the switching of the worm gear 8's rotation direction.

[0048] The drive mechanism includes a drive component 14. In this embodiment, the controller is a PLC controller and the drive component 14 is a motor. The drive component 14 is electrically connected to the controller. The drive component 14 is slidably fitted on the side wall of the housing 1. The output shaft of the drive component 14 and the sliding shaft 12 are coaxially and fixedly connected through a coupling.

[0049] The sliding mechanism includes a telescopic member 15 bolted to the outer wall of the housing 1. In this embodiment, the telescopic member 15 is an electric push rod, and the controller is electrically connected to the telescopic member 15. The output shaft of the telescopic member 15 is bolted to a slide rod 16, and the outer wall of the slide rod 16 is screwed to a connecting shaft 17. The end of the connecting shaft 17 away from the slide rod 16 is screwed to the outer wall of the sliding shaft 12.

[0050] The amplification mechanism includes a second fan blade 18 fixedly connected to the end of the sliding shaft 12 away from the drive member 14 by screws. The first screen cylinder 4 and the second screen cylinder 5 are both connected to an output pipe and an input pipe. The input pipes are all connected to the outside of the housing 1, and the output pipes are all connected to the air outlet pipe 2. The second fan blade 18 is rotatably fitted inside the air outlet pipe 2.

[0051] Combination Figure 4 As shown, the linkage mechanism includes several gates 19 rotatably fitted to the inner walls of the output and input pipes, each gate 19 having a fixedly connected opening and closing gear 20; a rack 21 is fixedly connected to the outer wall of the slide rod 16, and the opening and closing gears 20 mesh with the rack 21. In this embodiment, the opening and closing states of the gates 19 on the input and output pipes located on the same screen cylinder are opposite.

[0052] The specific implementation process is as follows: First, when oxygen inhalation is required, the device is powered on via the controller, and the device operates according to the preset program. Assuming that in the initial state, the first sieve cylinder 4 is in adsorption and purification mode, with its input gate 19 open and output gate 19 closed; the second sieve cylinder 5 is in desorption and regeneration mode, with its input gate 19 closed and output gate 19 open. The electric actuator (telescopic component 15) pushes the slide rod 16 to a certain end position, locking the above-mentioned gas path state through the meshing of the rack 21 and the opening / closing gear 20. Simultaneously, the slide rod 16 drives the sliding shaft 12 to the corresponding end position via the connecting shaft 17, causing a second bevel gear 13 on the sliding shaft 12 to mesh with a first bevel gear 11 on the worm gear 8, thus determining the initial power transmission path.

[0053] The motor (drive unit 14) starts, driving the sliding shaft 12 to rotate. The power is transmitted in two paths. The first path (purification path) transmits power through the rotation of the sliding shaft 12 to the first bevel gear 11 via the currently meshing second bevel gear 13, driving the worm 8 to rotate in a specific direction, such as forward. The worm 8, through meshing with the worm wheels 9 on both sides (screwing in and out effect), drives the two rotating shafts 10 to rotate the first fan blades 6 in the two sieve cylinders in opposite directions. Specifically, for example, the fan blades in the first sieve cylinder 4 rotate forward, promoting airflow and adsorbing nitrogen through the molecular sieve to purify oxygen. Meanwhile, the fan blades in the second sieve cylinder 5 rotate in reverse, forming a reverse airflow for exhaust, thereby achieving self-cleaning inside the molecular sieve and accelerating the desorption and regeneration of the molecular sieve.

[0054] As the second path (pressurized output path) rotates through the sliding shaft 12, the second fan blade 18 at its end rotates synchronously. Since the output pipe gate 19 of the second sieve cylinder 5 is opened at this time, the kinetic energy generated by the second fan blade 18 pressurizes the high-concentration oxygen that has been purified and stored in the second sieve cylinder 5 in the previous cycle, and delivers it to the breathing mask 3 through the outlet pipe 2 for the patient to inhale.

[0055] After a preset adsorption / desorption cycle (e.g., several minutes), the PLC controller issues a command, the electric actuator moves, and pulls the slide bar 16 to the other end; this action simultaneously triggers two sets of linkages. The air path switching linkage moves through the rack 21 on the slide bar 16, driving all the opening and closing gears 20 to rotate, thereby causing the gates 19 in each input pipe and output pipe to flip; causing the air path state of the first screen cylinder 4 to switch from inlet-open-exit to inlet-closed-exit, while the second screen cylinder 5 switches from inlet-closed-exit to inlet-open-exit, completing the airflow switching.

[0056] The power path switching linkage moves via the slide bar 16, which in turn drives the sliding shaft 12 to slide axially via the connecting shaft 17, causing the second bevel gear 13 on it to mesh with the first bevel gear 11. This switching changes the rotation direction transmitted to the first bevel gear 11, thereby causing the rotation direction of the worm gear 8 to reverse. The reversal of the worm gear 8 further causes the rotation directions of the first blades 6 in the two sieve cylinders to be reversed; the first sieve cylinder 4, which was originally in the adsorption state, switches to desorption, and the second sieve cylinder 5, which was originally in the desorption state, switches to adsorption.

[0057] After the above switching is completed, the device enters the next working cycle; the second sieve cylinder 5 begins to adsorb and purify fresh air, while the first sieve cylinder 4 undergoes desorption and regeneration. Meanwhile, the pressurized output of the second fan blade 18 continues. This cycle repeats, and through the movement of the sliding shaft 12 and a set of mechanical linkage components, the fan blade rotation (adsorption / desorption state), airflow on / off, and pressurization extraction target are simultaneously completed, achieving continuous high-concentration oxygen output with stable concentration and flow rate without the need for electronic valves and additional power components, meeting the needs of cluster headache treatment.

[0058] Example 2:

[0059] As attached Figure 2 As shown, the difference from Embodiment 1 is that the bottom of both the first sieve cylinder 4 and the second sieve cylinder 5 can be detachably connected to a collection box 22.

[0060] The specific implementation process is as follows: When a sieve cylinder enters the desorption regeneration state, its bottom collection box 22 captures and stores the nitrogen-rich waste gas, separated dust, and moisture generated during the desorption process; after the switching cycle is triggered and the sieve cylinder enters the adsorption purification state, its collection box 22 stops collecting. Users can periodically disassemble the collection box 22 for cleaning or replacement, thereby maintaining the cleanliness of the device's interior and its long-term operational efficiency. In this embodiment, the reverse-rotating first fan blade 6 pushes the residual nitrogen-rich gas in the sieve cylinder to the bottom, guiding it to the collection box 22, achieving pressure relief and flushing, and promoting molecular sieve regeneration.

[0061] Example 3:

[0062] The difference from Example 2 is that the surfaces of the first blade 6 and the second blade 18 are both coated with molecular sieve adsorption material.

[0063] The specific implementation process is as follows: When the first blade 6 rotates inside the sieve cylinder, the molecular sieve material on its surface moves at high speed with the blade, making full contact with the air, increasing the rate and efficiency of nitrogen adsorption, thereby enhancing the oxygen purification capacity; at the same time, when the second blade 18 rotates and pressurizes in the output pipe, the molecular sieve coating on its surface can further enhance the flow of oxygen, further capturing any trace amounts of nitrogen that may remain, ensuring that the concentration of output oxygen stably reaches the high purity standard required for treatment. This design makes molecular sieve adsorption no longer limited to the static sieve cylinder filling layer, but transforms it into a dynamic adsorption process through the rotating blades.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
