Application publication number CN114041922 A discloses a hyperbaric oxygen mask and its control method. The hyperbaric oxygen mask includes: a mask body comprising a first oxygen chamber, a second oxygen chamber, and an air inlet disposed between the first and second oxygen chambers; an oxygen pressurizing device for pressurizing oxygen after acquisition to obtain high-pressure oxygen, and delivering the high-pressure oxygen to the air inlet via a gas delivery hose; a gas pulser disposed inside the air inlet for pulse-pressurizing the high-pressure oxygen as it passes through the air inlet, delivering the high-pressure oxygen to the first and second oxygen chambers at a preset pulse frequency and preset speed; a pressure gauge disposed inside the first and second oxygen chambers respectively for measuring the pressure values ​​of the high-pressure oxygen in the first and second oxygen chambers; and a processing module disposed inside the mask body for adjusting the pressurization range of the oxygen pressurizing device and the gas pulser according to the high-pressure oxygen pressure value. This solution provides a way to maintain high-pressure oxygen in the eyes, but it also has the problem that the oxygen utilization rate in the oxygen chamber is low and it cannot directly act on the eyeball. Utility Model Content

[0003] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the objective of this invention is to provide a device that allows oxygen to be applied closer to the eyeball.

[0004] To achieve the above objectives, embodiments of this utility model provide a hyperbaric oxygen mask, comprising:

[0005] The goggles cover the eyes and consist of two separate mask bodies. Gaskets are placed where the mask bodies contact the skin. The gaskets are hollow and allow oxygen to flow through them.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] When this invention is in use, oxygen is introduced through the gasket, and the air supply hole allows it to be closer to the eyeball, thus ensuring that the oxygen concentration near the eyeball in the goggles remains at a relatively high level within the area.

[0023] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] Figures 1 to 3 A hyperbaric oxygen mask with constant pressure function according to an embodiment of the present invention includes:

[0026] The eye mask 1 covers the eyes and includes two independent mask bodies 11. A gasket 12 is provided at the position of the mask body 11 in contact with the skin. The gasket 12 is hollow and allows oxygen to flow through it. The side of the gasket 12 located inside the mask body 11 forms several air supply holes 121. Each of the two mask bodies 11 is provided with an adjustable pressure reducing valve 13.

[0027] Intake pipe 2 connects gasket 12 to the external oxygen supply system;

[0028] Headband 3: includes a loop strap 31 and a top strap 32. The two ends of the loop strap 31 are connected to the two sides of the cover 11, and the length is adjustable and elastic. One end of the top strap 32 is connected to the cover 11, and the other end is connected to the loop strap 31. The length is adjustable and it is not elastic. The included angle between the planes containing the loop strap 31 and the top strap 32 is variable.

[0029] This invention combines the air inlet pipe 2 of the eye mask 1 with the gasket 12, using the pressure of high-pressure oxygen to achieve a seal inside the eye mask 1. The air outlet is located close to the eyeball, ensuring that the area near the eyeball is always the region with the highest oxygen content in the cavity of the entire mask 11. Another benefit of this design is that at the beginning of treatment, the seal of the mask 11 is relatively low, and the incoming oxygen can quickly expel the original air inside through the gaps. During this process, the pressure rise inside the mask 11 is more gradual compared to existing closed structures, so patients will not immediately feel pressure on their eyeballs, thus improving comfort.

[0030] Because the oxygen is blown out from close to the eye socket, the skin around the eye socket can also increase the temperature of the blown oxygen by heating the gasket 12, making it closer to body temperature and reducing the feeling of coldness in the eyes after prolonged use.

[0031] Furthermore, the headband 3 in this design has been further improved. Existing structures, similar to swimming goggles, rely on the headband 3 to maintain a tight seal within the housing 11. However, this design does not require the headband 3 to be tightened initially, but this could lead to displacement during use. Therefore, the top strap 32 is provided to provide a three-dimensional fixation for the housing 11. Another function of the top strap 32 is to secure the input oxygen tube, preventing it from directly dragging the housing 11 and reducing air leakage.

[0032] In some designs, a guide ring 111 is provided inside the cover 11. The guide ring 111 is set along the gasket 12 to deflect the direction of the airflow blown out of the air outlet 121. Through this design, the direction of oxygen blowing out can be adjusted so that the final oxygen is blown as far as possible towards the eyeball, rather than towards the upper and lower eyelids, thereby increasing the local oxygen concentration and indirectly reducing the rate of oxygen input.

[0033] Optionally, the end of the air supply tube near the eye mask 1 is coiled to form a spring tube segment, which can reduce the restriction on the patient's movement when the head is turned. Moreover, the spring tube segment has a certain buffering effect, which can absorb some energy when the oxygen supply pressure of the external system fluctuates, making the pressure transition more gradual.

[0034] Furthermore, a heating element is provided inside the spring tube segment, which is fixed to the top band 32. The heating element can be a heating element powered by low-voltage DC, such as the heating insoles or heating gloves, using a power supply similar to a power bank. The purpose of this design is to increase the final oxygen temperature reaching the eye, making the patient more comfortable.

[0035] Optionally, the cover 11 is made of a light-transmitting material and has a detachable light shield. Some patients also have symptoms of photophobia. Using a light shield can help patients adapt better. The light-blocking area of ​​the light shield on the cover 11 is adjustable. It can completely block light or partially block light. It is even possible to set some shaped openings on the light shield, which can produce a certain visual effect, so that the patient's eyes have a visual focus during treatment and can maintain the action of keeping their eyes open and blinking, avoiding the decline in treatment effect due to eye fatigue and closing of the eyes.
