[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1 As shown, an oxygen pressure stabilizing device includes an oxygen storage unit and an air pushing mechanism. The oxygen storage unit is connected with an air inlet pipe 2 and an exhaust pipe 3. The air inlet pipe 2 can be connected with an oxygen pressure stabilizing tank 12. The oxygen in the oxygen pressure stabilizing tank 12 enters the interior of the cylindrical container 1 through the air inlet pipe 2 and is then discharged through the exhaust pipe 3. When the air pushing mechanism is powered off, the oxygen inside the oxygen storage unit is automatically pushed to allow the oxygen inside the oxygen storage unit to be discharged through the exhaust pipe 3, thereby maintaining a continuous oxygen supply when the power is off, and a gas flow regulating control valve 5 is installed on the exhaust pipe 3. The gas flow regulating control valve 5 can limit the flow rate of the exhaust pipe 3 when it is discharged, thereby controlling the pressure of the oxygen supply, and continuously inputting oxygen with stable pressure to the patient when the power is off.

[0020] Among them, the structure of the oxygen storage unit can be various. For example, the oxygen storage unit can be a flexible oxygen bag. When the air pushing mechanism pushes the flexible oxygen bag, the oxygen inside the flexible oxygen bag can be squeezed and discharged through the exhaust pipe 3.

[0021] like Figure 1-3 As shown, another structure of the oxygen storage unit is that the oxygen storage unit is a cylindrical container 1, the material of the cylindrical container 1 can be stainless steel or plastic, the air inlet pipe 2 and the exhaust pipe 3 are both connected to one end of the cylindrical container 1, and the air pushing mechanism includes an air pushing plate 9 slidably connected to the inside of the cylindrical container 1 and a linear moving part installed on the cylindrical container 1. When the linear moving part is powered off, the air pushing plate 9 is moved toward the direction close to the air inlet pipe 2 and the exhaust pipe 3, pushing the oxygen inside the cylindrical container 1 into the exhaust pipe 3 and discharged through the exhaust pipe 3.

[0022] like Figure 2-3 As shown, the linear moving part includes an electromagnet 11 fixedly connected to the end of the cylindrical container 1 away from the air inlet pipe 2. When the electromagnet 11 is energized, it is magnetically attracted to the push plate 9, and the push plate 9 is fixed in the position inside the cylindrical container 1 away from the air inlet pipe 2 and the exhaust pipe 3. A tension spring 10 is installed between the inner wall of the cylindrical container 1 close to the end of the air inlet pipe 2 and the push plate 9. When the electromagnet 11 is powered off, the tension of the tension spring 10 can drive the push plate 9 to move in the direction close to the exhaust pipe 3, pushing oxygen into the exhaust pipe 3, so that the push plate 9 can be automatically driven to move when the power is off, pushing oxygen into the exhaust pipe 3.

[0023] like Figure 2-4 As shown, in order to better supply gas to the interior of the cylindrical container 1, the end of the air inlet pipe 2 away from the oxygen pressure stabilizing tank 12 is connected to a rubber hose 6 located inside the cylindrical container 1, and a main exhaust hole 7 is provided at the end of the rubber hose 6 away from the air inlet pipe 2. A plurality of branch exhaust pipes 8 are provided on the rubber hose 6, so that oxygen can be input into multiple positions inside the cylindrical container 1 to achieve uniform ventilation.

[0024] Furthermore, the rubber hose 6 is a spiral pipe, so that oxygen can be more evenly input into the interior of the cylindrical container 1. At the same time, when the air pushing plate 9 moves, the rubber hose 6 will be squeezed, and the movement of the air pushing plate 9 is adapted to the extrusion deformation of the rubber hose 6.

[0025] At the same time, if Figure 1-3 As shown, in order to prevent the oxygen inside the cylindrical container 1 from being discharged through the intake pipe 2 and to allow the oxygen inside the cylindrical container 1 to be concentrated to supply oxygen to the exhaust pipe 3, a gas check valve 4 is installed on the intake pipe 2.

[0026] The working principle of the utility model is as follows: when powered on, the oxygen in the oxygen pressure stabilizing box 12 enters the interior of the cylindrical container 1 through the air inlet pipe 2, and then is discharged through the exhaust pipe 3 to supply oxygen to the oxygen mask worn by the patient. When an unexpected power outage occurs, the electromagnet 11 will automatically power off, and the tension of the tension spring 10 can drive the air push plate 9 to move toward the exhaust pipe 3, pushing the oxygen into the exhaust pipe 3 to complete the oxygen supply to the oxygen mask.

[0027] In summary, the present technical solution, by setting an oxygen storage unit between the oxygen pressure stabilizing tank 12 and the patient and an air pushing mechanism that automatically pushes the oxygen inside the oxygen storage unit when the power is off, can input oxygen with stable pressure to the patient when a short power outage occurs, thereby maintaining the oxygen supply to the patient for a short period of time when the power is off.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
