[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] In this embodiment, an oxygen bag oxygen supply flow control system is provided. When the oxygen pressure in the oxygen bag is low, the oxygen in the disposable oxygen bag can be actively drawn into the sealed cavity to form a pressure difference, so that the oxygen flows into the breathing duct, thereby ensuring that the oxygen in the disposable oxygen bag can be automatically and continuously supplied to the patient's breathing side. Figure 1 1 is a schematic structural diagram of an oxygen bag oxygen supply flow control system according to an embodiment of the present invention, including a catheter connection structure and a sealed shell 2, specifically as follows.

[0039] The catheter connection structure includes a sealed cavity 11 and an oxygen bag output catheter connection structure 12 and a breathing catheter connection structure 13 connected to the sealed cavity 11; wherein the oxygen bag output catheter connection structure 12 is provided with a first one-way valve 121 for controlling the one-way flow of oxygen from the oxygen bag into the sealed cavity 11, and the breathing catheter connection structure 13 is provided with a second one-way valve 131 for controlling the one-way flow of oxygen from the sealed cavity 11 to the breathing catheter. The oxygen bag output catheter connection structure 12 is used to connect the output catheter of the oxygen bag, and the breathing catheter connection structure 13 is used to connect the breathing catheter of the patient. The oxygen in the oxygen bag passes through the output catheter of the oxygen bag, the oxygen bag output catheter connection structure 12, the sealed cavity 11, the breathing catheter connection structure 13, the breathing catheter and the breathing mask in sequence. In addition, the first one-way valve 121 can be arranged at the sealing portion between the sealed cavity 11 and the oxygen bag output catheter connection structure 12, or can be arranged inside the oxygen bag output catheter connection structure 12, and the second one-way valve 131 is preferably arranged at the connection between the sealed cavity 11 and the breathing catheter connection structure 13.

[0040] The oxygen bag used in this embodiment can be a disposable oxygen bag, which is usually made of high-pressure resistant, non-toxic, and odorless medical-grade polyester material to ensure that it is not easily damaged during use and is suitable for medical first aid and daily oxygen therapy. The shape of the oxygen bag can be rectangular or cylindrical, and it is independently compressed and packaged as a disposable product, which is easy to carry and store. A rubber catheter is provided in one corner of the oxygen bag for connecting the oxygen bag oxygen supply flow control system or oxygen supply equipment such as an oxygen mask or a nasal cannula. The use design of the disposable oxygen bag avoids the risk of cross infection, and each bag is strictly disinfected to ensure the health and safety of the user. After the oxygen bag is filled with oxygen, oxygen supply can be provided to the patient through simple operation without complicated settings or maintenance.

[0041] The sealed housing 2 is sealed and connected with the sealed cavity 11. A regulating pump is arranged in the sealed housing 2. The regulating pump is used to extract oxygen from the sealed cavity 11 and release it into the sealed cavity 11. The regulating pump can be a micro pump, such as a brushless motor DC air pump, a micro diaphragm pump, etc. Under the action of the first one-way valve 121 and the second one-way valve 131, the regulating pump is mainly used to extract oxygen from the oxygen bag and increase the oxygen pressure in the sealed cavity 11. Under the action of the oxygen pressure, the oxygen is then transported to the breathing catheter through the second one-way valve 131, so that the oxygen in the oxygen bag can be actively transported, avoiding manual squeezing and reducing the difficulty of operation.

[0042] The oxygen bag oxygen supply flow control system provided by the present invention can be adapted to oxygen bags of different capacities. During the oxygen supply process of the oxygen bag, after the pressure in the oxygen bag gradually decreases, the oxygen in the oxygen bag can be assisted by adjusting the pump to increase the oxygen pressure on the oxygen supply side, thereby ensuring the continuous supply of oxygen to the patient's breathing side, and providing the patient with high-concentration oxygen to alleviate symptoms such as dyspnea and hypoxia. This not only saves manual squeezing operations, but also ensures the continuous supply of oxygen, improving the patient's oxygen therapy experience. In addition, the oxygen bag oxygen supply flow control system provided by the present invention also has certain flexibility and portability, and can select oxygen bags of different capacities for control according to different application requirements, and can be recycled. Moreover, the oxygen bag oxygen supply flow control system is easy to carry and suitable for various application scenarios.

[0046] In this embodiment, the oxygen pressure can be detected in real time by the pressure monitoring module. For example, when the oxygen pressure is less than 1L / min, the regulating pump is automatically started to extract oxygen to increase the oxygen pressure. The specific control process of the regulating pump can be precisely controlled by methods such as PID control.

[0047] In this embodiment, the pressure monitoring module can monitor the oxygen pressure in the sealed cavity 11 in real time to ensure that the oxygen pressure is always maintained within a safe and effective range, thereby ensuring a continuous supply of oxygen.

In addition, the design of disposable oxygen bags is not only lighter and easier to carry, but also can effectively reduce the burden on patients or users, and meet the different needs of users.

[0059] In some optional embodiments, the oxygen bag determination unit is disposed inside the sealed housing 2. The oxygen bag determination unit in this embodiment can be integrated inside the sealed housing 2 to reduce the volume of the control system and improve convenience.
