[0002] Oxygen bags are bags used to hold oxygen, primarily made of non-toxic, chemically neutral materials. They are portable, easy to use, and suitable for home healthcare as well as emergency medical transport in medical facilities. However, during use, the oxygen flow gradually decreases as the pressure inside the bag drops. When the internal and external pressures reach equilibrium, the oxygen cannot escape completely. Simply squeezing the bag by hand is insufficient to fully extract the oxygen, and maintaining pressure continuously is laborious.
[0003] Utility model CN204995945U discloses an adjustable medical oxygen bag, comprising a rectangular bag body. An inflation port and an exhaust port are formed at the edge of the short side of one side of the bag body. Springs are embedded at the edges of the two long sides of the bag body, and the springs can be wound into a disc shape. Clips are also movably attached to the bag body. This utility model is integrated with the oxygen bag, making it impossible to detach the pressurization device for immediate use on a second oxygen bag. This results in resource waste when using multiple oxygen bags consecutively. Summary of the Invention

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.
[0024] Example 1: As Figure 1 , 2 As shown in Figures 4, 5, and 6, an oxygen bag pressurization device includes a clamp 1. The clamp 1 includes an upper clamp plate 11 and a lower clamp plate 12. The rear end of the upper clamp plate 11 is movably connected to the rear end of the lower clamp plate 12. The other end of the upper clamp plate 11 is connected to the lower clamp plate 12 via a fixing component 2, which is a snap-fit structure. The lower clamp plate 12 is provided with an adjusting strap 3. Both the clamp 1 and the adjusting strap 3 are made of plastic, resulting in low cost. The front end of the lower clamp plate 12 is provided with a first cavity for accommodating the adjusting strap 3 and a... The first cavity has a first opening 121 that connects to the outside; the rear end of the lower clamping plate 12 is provided with a second cavity for accommodating the adjustment belt 3 and a second opening 122 that connects the second cavity to the outside. One end of the adjustment belt 3 is provided with a limiting member that extends into the first cavity. The size of the limiting member is larger than the size of the first opening 121. The limiting member is fixedly connected to the adjustment belt 3 and is located in the first cavity, so that one end of the adjustment belt 3 cannot be completely detached from the first cavity, and the other end of the adjustment belt 3 extends into the second cavity.
[0025] like Figure 3 , 6As shown, the second opening 122 has symmetrically distributed sliding grooves 123 on both sides. The second opening 122 is provided with a locking assembly 4 for fixing the adjusting band 3. The locking assembly 4 includes a fixing block 41 that can close the second opening 122. The back sides of the fixing block 41 are provided with symmetrically distributed sliders, which slide in cooperation with the sliding grooves 123. The adjusting band 3 has a number of equidistant protrusions 31. The protrusions 31 are triangular and have inclined surfaces. The inclined surfaces are located on the side away from the limiting member. When the adjusting band 3 enters the second cavity, the inclined surfaces on the protrusions 31 contact the fixing block 41. At this time, the contact area between the two is small and the contact surface is smooth, which makes it convenient for the protrusions 31 to lift the fixing block 41. When no external force is applied to the adjusting band 3, the contact area between the protrusions 31 and the fixing block 41 is large, so that the protrusions 31 cannot lift the fixing block 41, thus preventing the adjusting band 3, which has already entered the second cavity, from sliding out of the second opening 122.
[0026] like Figure 3 , 6 As shown, the locking assembly 4 also includes locking blocks 42 disposed on both sides of the fixing block 41. The locking block 42 includes a connecting part and a locking part. One end of the connecting part is fixed to the rear end of the lower clamping plate 12, and the other end of the connecting part extends to the rear of the lower clamping plate 12 and connects with the locking part. One end of the locking part faces the lower clamping plate 12. When no external force is applied, the distance between the locking part and the lower clamping plate 12 is less than the thickness of the fixing block 41. The locking part can be manually pried outward to make the distance between the locking part and the lower clamping plate 12 greater than the thickness of the fixing block 41. The locking block 42 strengthens the fixing effect of the fixing block 41 on the adjusting belt 3.
[0027] The operating principle of Example 1: Clamp the oxygen bag with clamp 1, clamp one side of the oxygen bag with fixing component 2, roll up the oxygen bag to gradually increase the air pressure inside the oxygen bag. When it is rolled up to a suitable position, lift the fixing block 41 and push the adjusting belt 3 into the second cavity. At this time, the area between the adjusting belt 3 and the lower clamping plate 12 gradually decreases, thereby fixing the rolled-up part of the oxygen bag. Put down the fixing block 41 and press the locking block 42 on both sides of the fixing block 41 to completely fix the adjusting belt 3 and prevent the rolled-up oxygen bag from springing back.
[0028] Example 2: Figure 7As shown, an oxygen bag pressurization device includes a clamp 1, which includes an upper clamp 11 and a lower clamp 12. One end of the upper clamp 11 is movably connected to one end of the lower clamp 12, and the other end of the upper clamp 11 is connected to the lower clamp 12 through a fixing component 2, which is a buckle. The lower clamp 12 is provided with an elastic band 5 and a connector for connecting the two ends of the elastic band 5. The connectors are symmetrically arranged at both ends of the lower clamp 12, and the connectors are hooks 51. The two ends of the elastic band 5 are connected to the hooks 51.
[0029] The operating principle of Example 2: Clamp the oxygen bag with the clamp 1, clamp one side of the oxygen bag with the fixing component 2, roll up the oxygen bag to gradually increase the air pressure inside the oxygen bag. When it is rolled up to a suitable position, connect the two ends of the elastic band 5 to the two hooks 51 respectively, so as to fix the rolled-up part of the oxygen bag and prevent it from rebounding.
