[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] Please refer to Figure 1 - Figure 3 It is illustrated that the medical artificial respiration auxiliary device in embodiment 1 comprises a connecting mask 1, a gas pipe 2 is fixedly connected to the center position of the right side of the connecting mask 1, an airflow channel 3 is arranged between the gas pipe 2 and the connecting mask 1, a one-way valve 4 is fixedly connected to the right end of the gas pipe 2, a fixed tube 5 is fixedly connected to the right end of the one-way valve 4, a safety valve 6 is connected to the top of the fixed tube 5, a breathing bag 7 is detachably connected to the right side of the fixed tube 5, an inlet valve 8 is fixedly connected to the right end of the breathing bag 7, an inlet pipe 9 is connected to the right side of the inlet valve 8, a connecting pipe 10 is arranged at the bottom of the inlet pipe 9, and the connecting pipe 10 and the inlet pipe 9 are both in communication with the inside of the breathing bag 7 through the inlet valve 8.

[0026] Please refer to Figure 2 and Figure 3 It is illustrated that the connecting mask 1 is integrally formed by using medical plastic material, and the connecting mask 1 is adapted to the face of the human body.

[0027] In this embodiment, when artificial respiration is needed for a patient, medical staff first fix the connecting mask 1 on the face of the patient, and then make air enter the respiratory tract of the patient through the fixed tube 5, the one-way valve 4, the gas pipe 2 and other components by pressing the breathing bag 7. In the pressing process, the soft and durable characteristics of the breathing bag 7 can ensure the comfort and continuity of the pressing, at the same time, the one-way valve 4 is used to ensure that air can only flow in one direction, so as to prevent the reverse flow of gas from causing discomfort or pollution to the patient, in addition, the safety valve 6 can automatically release excess gas when the pressure exceeds the set value, so as to ensure that the air pressure will not be too high in the pressing process, thereby protecting the safety of the respiratory tract of the patient. The connecting mask 1 is made of medical plastic material, which is light and easy to clean and disinfect, and has high adaptability to the face of the human body, thereby reducing the risk of air leakage.

[0028] It should be noted that the airflow channel 3 facilitates the delivery of gas generated by chest compressions to the area near the patient's mouth inside the connecting mask 1, thereby effectively performing artificial respiration. The connecting tube 10 is used to connect to an external oxygen source to provide a continuous and stable oxygen supply, ensuring a rapid and convenient initiation of the oxygen supply process in emergencies. This design not only improves the practicality of the device but also further enhances its reliability in medical emergency care.

[0029] Example 2

[0030] Please see Figure 1 and Figure 4 Example 2 is described below. This embodiment further illustrates Example 1. In the figure, connecting straps 11 are fixedly connected to the edges of the front and rear sides of the connecting mask 1. The connecting mask 1 is connected to the patient's head through the connecting straps 11.

[0031] Furthermore, the check valve 4 is a duckbill valve, and the safety valve 6 is a pressure regulating valve;

[0032] In this embodiment, connecting straps 11 are provided on both the front and rear sides of the connecting mask 1, which can be adjusted according to the size of the patient's head to ensure that the mask is firmly fixed to the patient's face and will not fall off due to the patient's movements, thereby improving the safety of use and the efficiency of artificial respiration. The one-way valve 4 adopts a duckbill valve, which can effectively control the one-way flow of airflow, ensuring that gas can only be transmitted from the breathing bag 7 to the patient's airway in one direction, avoiding gas backflow and improving the efficiency and safety of artificial respiration. The safety valve 6 adopts a pressure regulating valve. When the breathing bag 7 is pressed to generate high pressure, if the pressure exceeds the set value, the pressure regulating valve will automatically open to release excess gas, thereby preventing excessive air pressure from damaging the patient's airway.

[0033] Example 3

[0034] Please see Figure 5 and Figure 6 Example 3 is described below. This embodiment further illustrates Example 2. In the figure, a sealing ring 12 is provided at the connection between the fixing tube 5 and the breathing bag 7, and the fixing tube 5 is connected to the breathing bag 7.

[0035] Furthermore, several auxiliary grooves 13 are provided around the outer wall of the breathing bag 7, and the breathing bag 7 is made of soft and durable medical silicone material in one piece.

[0036] In the embodiment, the sealing ring 12 is arranged at the connection between the fixed tube 5 and the breathing bag 7, so that the leakage of gas at the connection is effectively prevented, and the sealing performance of the breathing aid device is ensured.

[0037] Specifically, the auxiliary groove 13 can be more smoothly folded and unfolded when the breathing bag 7 is compressed, and the resistance in the compression and release process is reduced, so that the medical staff can operate more easily, and the compression efficiency is improved.

[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
