Description

Technical Field

[0001] The present invention relates to the technical field of oxygen supply devices, in particular to a head massage oxygen supply device. Background Art

[0002] Modern people's health problems (such as sub-healthy emotions and chronic diseases) are mostly caused by the physiological perception of environmental stressors, including low oxygen, air pressure changes, temperature fluctuations, noise pollution, etc. These factors are transmitted to the brain through the senses such as breathing, touch, and hearing, causing a decrease in blood oxygen (SpO2 in plateau areas can be as low as 82.5%), autonomic nervous system disorders (abnormal heart rate variability HRV), sleep disorders (average sleep onset time is 42 minutes) and neuralgic headaches. In response to these situations, oxygen enrichment intervention is a common treatment method for groups in high-altitude areas with low blood oxygen concentrations caused by low air pressure and hypoxia. Oxygen enrichment refers to an environment with an oxygen concentration higher than the normal atmospheric level (about 20.9%). In the medical field, an environment with an oxygen concentration between 25% and 30% is usually called an oxygen-rich environment, also known as the vital oxygen state. In this environment, the human body's physical and intellectual strength can reach its optimal state, significantly reducing the symptoms of altitude sickness and difficulty sleeping, thereby effectively improving sub-health problems.

[0003] Regarding the existing related technologies, the inventor believes that the following defects exist: the existing oxygen inhalation methods include diffusion, nasal inhalation, mask, hyperbaric oxygen chamber, etc. Among them, the head needs to bear the weight of the entire mask structure when wearing mask-type oxygen inhalation. Long-term wearing can easily cause discomfort to the person, and the mask lacks limiting measures and is easy to move with the deflection of the person's head. Even after the person's head is returned to its original position, the mask is still in a misaligned state. At this time, there will be misalignment between the oxygen supply port and the person's face, affecting the subsequent oxygen inhalation quality. At the same time, the structure is simple and cannot meet the diverse needs of people, which reduces the practicality of the device and there is a certain room for improvement.

[0004] Traditional oxygen cylinders and concentrators rely on passive inhalation, resulting in low oxygen utilization and an inability to address low air pressure. They typically take 10-15 minutes to become effective. This design utilizes a sealed environment combined with active pressurization, increasing oxygen permeability by 40%. A weakly high-pressure environment is created in the head, with pressure compensation of +0.1 bar to +0.5 bar, improving the user's blood oxygen concentration within 5 minutes. Currently, high-altitude oxygen inhalation in high-altitude areas only increases oxygen concentration, without compensating for the reduced oxygen partial pressure in the respiratory system caused by low atmospheric pressure. Hyperbaric oxygen chambers are also very rare due to their bulky size and high equipment cost. This design, however, achieves a comprehensive improvement in oxygen concentration, increased pressure compensation at the respiratory site, and increased oxygen partial pressure, thereby enhancing oxygen inhalation effectiveness.

[0005] This design utilizes a triple synergistic intervention approach, combining dynamic oxygen enrichment, pressure compensation, and neuromodulation, integrated into a head-mounted device. This system transcends the limitations of traditional oxygen therapy, which only addresses hypoxia. Instead, it addresses the physiological root of altitude sickness (hypoxia → hypercompensation → organ damage), providing a portable and efficient solution for high-altitude health protection. This approach maintains fairness in high-altitude healthcare, redefines the equality of the "right to breathe," and achieves universal access to oxygen. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a head massage oxygen supply device.

The surface is pasted with a detachable skin-friendly layer (non-woven fabric), which can be quickly replaced with Velcro to ensure hygiene. Key connection: The neck airbag (silicone material) is sealed with the top edge of the oxygen supply helmet through a high-frequency heat sealing process to form an annular sealed cavity.

In the present application, the adjusting screw can be rotated according to the actual use requirements to adjust the oxygen supply helmet to a certain extent, so that there is a certain gap between it and the top of the person's head, avoiding direct contact with the person's head and causing excessive pressure on the top of the head, thereby affecting the comfort of the person during oxygen supply. In addition, before wearing the oxygen supply helmet, a clean skin-contacting layer can be pasted on the surface of the internal flexible layer to ensure the cleanliness of the oxygen supply environment, avoid the generation of odor caused by impurities such as sweat caused by long-term wearing, ensure the environment is comfortable during oxygen supply, and thus improve the comfort of the person; 3. In the present application, the position of the oxygen supply helmet can be fixed by the cooperation of structures such as the shoulder rest and the chest strap to ensure stability during oxygen supply, and then the pressure applied to the top of the head can be adjusted by rotating the adjusting screw to ensure the comfort of the personnel. Then, the designated acupuncture points on the personnel's head can be massaged by the internal massage carrier to soothe the personnel's body and mind. During oxygen supply, the liquid or liquid food in the pressurized water cup can be drunk through the straw, and the personnel can replenish water and eat without opening the mask, thereby extending the oxygen supply time and reducing gas leakage. The coordinated use of multiple groups of different structures can effectively enrich the functionality of the device while ensuring comfort during oxygen supply, facilitate better and more practical use, and adapt to changing environmental conditions in multiple scenarios.

Physical parameter linkage: Oxygen pressure regulation: The oxygen concentrator 20 uses the data from the blood oxygen sensor (MAX30102, accuracy ±2%) through a PID algorithm (Kp=0.8, Ki=0.05, Kd=0.1) dynamically adjusts oxygen concentration (20.9%--95%), and works with air pump 21 to compensate for altitude pressure differences (e.g., maintaining an equivalent pressure of 100kPa at 5000 meters). Temperature regulation: A semiconductor refrigeration chip (TEC1-12706) is installed in the resin shell of the neck airbag 14. The N-level surface is connected to the outer aluminum heat sink fins (surface area 120cm²) of the shell, and the P-level surface contacts the airbag cavity via a flexible thermal pad. The temperature control range is 18-45°C with an accuracy of ±0.5°C, enabling switching between cold and hot compress modes. Audio resonance: An FFT algorithm analyzes heart rate variability (HRV) to generate isochronous pulse audio (frequency 20-150Hz, amplitude ≤70dB), which is played through Dolby Headphones and regulates heart rate using the principles of physical resonance (e.g., alpha wave music is generated when HR>100bpm, with a target heart rate of 80bpm).

[0035] The use principle of a head massage oxygen supply device in this embodiment is as follows: during use, a person can directly wear the oxygen supply helmet 1, and at this time, the person's head can be inserted into the internal position of the oxygen supply helmet 1 through the opening between the neck airbag 14 and the oxygen supply helmet 1, and then the mask 16 is placed on the groove on the surface of the oxygen supply helmet 1 and pressed. At this time, the mask 16 can be stuck on the surface position of the oxygen supply helmet 1 through the surrounding sealing strips 22, thereby achieving a sealing operation on the oxygen supply helmet 1, avoiding gas leakage during subsequent oxygen supply, ensuring the oxygen supply quality and oxygen supply pressure (1.2ATA--1.5ATA), and effectively compensating for the air pressure difference in high-altitude applications. In addition, the surface of the mask 16 is respectively provided with an inhalation pipe 19 and an outlet pipe 18, which can be used to inhale air. The pipe 19 is used to introduce the enriched oxygen generated by the oxygen generator 20 and input by the air pump 21. At this time, the interior of the oxygen supply helmet 1 is an oxygen-rich environment, which is used for personnel to breathe oxygen, and the exhaust gas generated by oxygen inhalation can be discharged in time through the exhaust pipe 18, so as to realize the flow operation of the gas and ensure the normal state of the overall oxygen inhalation. After the oxygen supply helmet 1 is installed, the personnel can rotate the adjusting screws 3 on both sides according to the different pressure conditions of the top of the internal top of the oxygen supply helmet 1 on the top of their own heads. At this time, the adjusting screw 3 can drive the adjusting plate 2 to move up and down by a certain range when it rotates. When it moves up and down, the oxygen supply helmet 1 can be adjusted up and down by a certain range, so as to adjust the pressure of the oxygen supply helmet 1 on the top of the personnel's head, thereby improving the quality of the oxygen supply helmet 1. Improve the wearing comfort of personnel, extend the wearing time that personnel can bear, avoid the oxygen supply structure being fixed and unable to be adjusted, resulting in the inability to adapt well to the needs of different personnel, ensure its wearing comfort, prevent the fixed position from causing head squeezing and face squeezing, and can be adjusted independently and in time to improve the overall quality of use. Moreover, after the oxygen supply helmet 1 is just worn, the neck airbag 14 will naturally be located at the periphery of the personnel's neck, thereby sealing the neck area to prevent gas leakage. At the same time, the shoulder supports 13 on both sides of the neck airbag 14 will naturally be located at the shoulder position of the human body, and a shoulder-shaped groove is provided at the bottom of the shoulder support 13, and a soft pad is provided inside. The entire oxygen supply structure is supported at the shoulder position of the human body through the groove, dispersing the pressure on the head and avoiding the head from bearing The entire weight causes discomfort to the person, and at the same time, the two sides of the shoulder support 13 are fixed by the Velcro 7 arranged on the surface. At this time, the shoulder support 13 can be fixed to the shoulder position, thereby achieving the fixation of the oxygen supply structure, avoiding it from being offset and dislocated when the person's head turns, and preventing it from affecting subsequent use. For example, after the head turns, the structure is dislocated, and when the head turns back, the structure does not change. At this time, the initial relationship between the person and the structure is offset, causing discomfort to the person, making it impossible to observe the external situation well or causing the observation effect of the VR video component 23 to be reduced. Moreover, after the shoulder support 13 is fastened, the chest strap 10 wrapped around the chest position and the Velcro 7 on its surface and other fixing structures are used to assist in the fixation of the above-mentioned shoulder support 13.The overall restraint effect is improved, thereby improving the restraint effect on the head oxygen supply structure, ensuring its stability and use effect, and a cup bag 6 for placing a pressurized water cup 5 is provided on the surface of the chest strap 10. By placing the pressurized water cup 5 in the cup bag 6 and connecting one end of the straw 4 on the top of the pressurized water cup 5 to the opening reserved on the surface of the mask 16, the straw 4 can be inserted into the interior of the oxygen supply helmet 1 and then toward the mouth position of the person, thereby realizing hydration or eating without opening the mask 16, so that the person can perform oxygen supply operation for a long time, enriching the functionality of the device and improving its practicality, and providing The flexible layer 30 on the inside of the oxygen helmet 1 is attached with a removable skin-contacting layer 29 via Velcro 7. This allows for easy removal and replacement of the skin-contacting layer 29 after each oxygen supply. This prevents contamination of the inner wall caused by long-term contact between the user and the single inner wall, ensuring the cleanliness of the oxygen supply environment, ensuring oxygen supply safety, and improving the effectiveness of the device. Furthermore, during oxygen supply, the massage carrier 24 inside the oxygen helmet 1 can massage designated acupuncture points on the user's head, enhancing the user's experience of oxygen supply and soothing the user's body and mind, facilitating better use. The device as a whole has the advantages of stable structure, high comfort, and diverse functions.
