[0002] Oxygen bags are bags used to hold oxygen. They are mainly made of non-toxic materials with no harmful chemical effects. Oxygen bags are easy to carry and simple to operate. They can be used for home health care and for emergency transportation in medical units. However, the oxygen bag connecting tube of the existing oxygen bag is connected to the oxygen supply tube by direct insertion. This connection method is not strong enough. When pulled by external force, the oxygen bag connecting tube and the oxygen supply tube are easily separated, making it impossible to transport oxygen normally. For this reason, we propose an oxygen bag connector. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 , Figure 2 , Figure 3 The utility model provides a technical solution: an oxygen bag connector, including an oxygen bag connecting tube 1 and an oxygen supply tube 2, the oxygen supply tube 2 is at one end of the oxygen bag connecting tube 1, a connecting assembly is arranged between the oxygen bag connecting tube 1 and the oxygen supply tube 2, the connecting assembly includes a first connecting tube 3, the first connecting tube 3 is at one end of the oxygen bag connecting tube 1, a second connecting tube 4 is arranged on one side of the first connecting tube 3, the second connecting tube 4 is at one end of the oxygen supply tube 2, the second connecting tube 4 is connected to the oxygen supply tube 2, an isolation tube 5 is fixedly connected to the inner side of the first connecting tube 3, and the first connecting tube 3 and the isolation tube 5 are connected. A spring 6 is provided, one end of the spring 6 is fixedly connected to the inner surface of the first connecting tube 3, the other end of the spring 6 is fixedly connected to a movable ring 7, a first rubber sealing ring 8 is provided on one side of the movable ring 7, a second rubber sealing ring 9 matched with the first rubber sealing ring 8 is provided on a side surface of the second connecting tube 4 close to the first connecting tube 3, and a connecting rod 10 is fixedly connected to the top end surface and the bottom end surface of the second connecting tube 4, one end of the connecting rod 10 is rotatably connected to a movable frame 11, and a fixed frame 12 matched with the movable frame 11 is provided on the top end surface and the bottom end surface of the first connecting tube 3;

[0019] When it is necessary to connect the oxygen bag connecting tube 1 with the oxygen supply tube 2, first take the oxygen supply tube 2 to the appropriate position, so that the oxygen supply tube 2 drives the second connecting tube 4 to be inserted between the first connecting tube 3 and the isolation tube 5. At this time, the second connecting tube 4 pushes the movable ring 7 to move toward the inside of the first connecting tube 3. At this time, the spring 6 is forced to shrink. When the second connecting tube 4 reaches the appropriate position, the movable frame 11 is rotated around one end of the connecting rod 10 so that the inner side of the movable frame 11 passes through the fixed frame 12 and remains parallel to the fixed frame 12. Then the force on the second connecting tube 4 is withdrawn. At this time, the spring 6 is not forced to open, and the spring 6 pushes the movable ring 7 back to its original position. During the movement of the movable ring 7, the second connecting tube 4 is pushed to one side, so that the movable frame 11 is stuck in the inner side of the fixed frame 12, completing the connection and fixation of the first connecting tube 3 and the second connecting tube 4. At the same time, under the interaction of the first rubber sealing ring 8 and the second rubber sealing ring 9, the first connecting tube 3 and the second connecting tube 4 maintain good sealing performance, and the operation of connecting the oxygen bag connecting tube 1 and the oxygen supply tube 2 is completed; when the oxygen bag connecting tube 1 of the existing oxygen bag is connected to the oxygen supply tube 2, it is connected by direct insertion. Such a connection method is not strong enough. When pulled by external force, it is easy to cause the oxygen bag connecting tube 1 and the oxygen supply tube 2 to fall off, so that oxygen cannot be transported normally; by designing the oxygen bag connecting tube 1, the oxygen supply tube 2, and the connecting assembly, the oxygen bag connecting tube 1 and the oxygen supply tube 2 can be firmly connected together, and even if pulled by external force, they will not fall off, which ensures that the oxygen inside the oxygen bag can be transported out normally. At the same time, the overall structure is compact and the installation is simple, which is worthy of popularization and use.

[0020] In this embodiment, preferably, a protection component is also included, which includes a first slide cylinder 13, the first slide cylinder 13 is slidably sleeved on the surface of the oxygen bag connecting tube 1, a second slide cylinder 14 is provided on one side of the first slide cylinder 13, the second slide cylinder 14 is slidably sleeved on the surface of the oxygen delivery tube 2, an external thread 16 is provided on the outer surface of the second slide cylinder 14, and an internal thread 15 matched with the external thread 16 is provided on the inner surface of the first slide cylinder 13;

[0021] By designing a protective component, after the oxygen bag connecting tube 1 and the oxygen supply tube 2 are connected, the medical staff can pull the first slide cylinder 13 and the second slide cylinder 14 to bring the two sides closer, and then rotate the second slide cylinder 14 to the inside of the first slide cylinder 13, so that the first slide cylinder 13 and the second slide cylinder 14 wrap the connecting component, thereby protecting the connecting component.

[0022] In this embodiment, preferably, the first rubber sealing ring 8 and the second rubber sealing ring 9 have the same size; so that after the first rubber sealing ring 8 and the second rubber sealing ring 9 are pressed against each other, the sealing between the oxygen bag connecting tube 1 and the oxygen supply tube 2 is better.

[0023] In this embodiment, preferably, there are six springs 6, which are distributed in a ring shape and at equal distances on the other side surface of the movable ring 7; this makes the movable ring 7 have a stronger squeezing effect on the second connecting tube 4, thereby ensuring a tighter connection between the oxygen bag connecting tube 1 and the oxygen supply tube 2.

[0024] In this embodiment, preferably, the connecting rod 10, the movable frame 11, and the fixed frame 12 are all made of plastic, thereby reducing the investment in manufacturing cost.

[0025] In this embodiment, preferably, the outer surface of the first slide cylinder 13 is provided with anti-skid patterns, which has a strong anti-skid effect and facilitates medical staff to better connect the first slide cylinder 13 and the second slide cylinder 14 together.
