[0029] Embodiment 1:

[0030] See also Figure 1-4 A walking aid capable of providing mobile oxygen supply to elderly patients comprises a carrying plate 1, a pair of placing tubes 6 and a pressing airbag 10. The upper end of the carrying plate 1 is fixedly connected to a bottom plate 2, and the upper end of the bottom plate 2 is fixedly connected to a plurality of lifting rods 3, the lifting rods 3 are electric telescopic rods, the bottom end of the carrying plate 1 is fixedly connected to a battery, and the lifting rods 3 are electrically connected to the battery, and the height of the top plate 4 can be adjusted by the electric telescopic rod, so that it can adapt to users of different heights, the upper ends of the plurality of lifting rods 3 are fixedly connected to the top plate 4, and the inner end of the top plate 4 is fixedly connected to a storage box 5, and a mask is arranged in the storage box 5, and a transparent cover is hinged on the upper end of the storage box 5, and the mask placed in the storage box 5 is shielded by the transparent cover to prevent dust from sticking to its surface, and a pair of placing tubes 6 and a pressing airbag 10 are provided. The placement tube 6 is fixedly connected to the upper end of the supporting plate 1, and the placement tube 6 is located at the front end of the bottom plate 2. An oxygen supply tank 7 is arranged in the placement tube 6. A connecting pipe 8 is fixedly connected to the upper end of the oxygen supply tank 7. A three-way pipe 9 is fixedly connected between a pair of connecting pipes 8, and the three-way pipe 9 is fixedly connected to the mask. The pressing airbag 10 is fixedly connected to the end of the bottom plate 2 away from the supporting plate 1. The pressing airbag 10 is fixedly connected to the three-way pipe 9 through a pipeline, and is supported by the user through the top plate 4 to help move it, and the mask is taken out of the storage box 5 and worn. Oxygen is supplied by inhaling with the help of the oxygen supply tank 7, and pressure can also be applied to the pressing airbag 10 so that the gas in the pressing airbag 10 enters the three-way pipe 9 to open it, so that oxygen is automatically discharged from the oxygen supply tank 7 to the mask for oxygen supply.

[0031] The placement tube 6 includes a tube frame 61, which is fixedly connected to the upper end of the supporting plate 1. A screw hole is provided at the outer end of the tube frame 61, and a bolt 62 is threadedly connected to the screw hole. A fastening plate 63 is provided at the inner end of the tube frame 61, and the fastening plate 63 is rotatably connected to the bolt 62. The oxygen supply tank 7 is fixed by placing it in the placement tube 6, and the bolt 62 is twisted to make the fastening plate 63 press against the oxygen supply tank 7, so that oxygen supply tanks 7 of different sizes can be fixed.

[0032] The placement tube 6 also includes a sponge pad 64, which is fixedly connected to the inner end of the tube frame 61. A through hole matching the fastening plate 63 is opened in the middle of the sponge pad 64.

The oxygen control component 94 is opened by applying pressure to the pressing airbag 10, so that oxygen enters the oxygen tube 92 from the docking tube 91 and is discharged from the mask for oxygen supply.

[0034] The three-way pipe 9 also includes a pair of one-way valves 93, which are fixedly connected to one end of the docking pipe 91 close to the connecting pipe 8. The one-way valves 93 can prevent the gas in the compression airbag 10 from entering the connecting pipe 8, while the oxygen flowing from the oxygen supply tank 7 to the connecting pipe 8 can pass through the one-way valves 93 and enter the docking pipe 91.

[0035] The oxygen control component 94 includes an internal cylinder 941, which is fixedly connected to the inner end of the oxygen inhalation tube 92, and a sealing plate 942 is slidably connected to the inner end of the internal cylinder 941. A pair of limiting grooves are provided on the inner wall of the internal cylinder 941, and a limiting block 943 is slidably connected in the limiting groove. A pair of limiting blocks 943 are fixedly connected to a connecting plate 944 at one end close to each other, and the connecting plate 944 is fixedly connected to the sealing plate 942, and a micro spring 94 is fixedly connected between the limiting block 943 and the inner wall of the limiting groove. 5. By pressing the gas in the airbag 10 to enter the oxygen inhalation tube 92 and push the sealing plate 942, the middle of the built-in tube 941 is opened. Under the rebound force of the micro spring 945, the limit block 943 can be driven to make the connecting plate 944 pull the sealing plate 942 to block the middle of the built-in tube 941 again to prevent the loss of oxygen in the oxygen supply tank 7. The user can also suck the sealing plate 942 out of the built-in tube 941 by inhaling hard, which can also open the middle of the built-in tube 941 and allow the gas to circulate.

[0036] A pair of auxiliary plates 11 are hinged on the inner wall of the bottom plate 2, and the hinge adopts damping rotation. By rotating and lowering the pair of auxiliary plates 11, a step can be formed, so that the user can sit down and rest.

[0037] The lower end of the carrying plate 1 is fixedly connected with moving wheels 12 all around, and the moving wheels 12 are universal wheels. The moving wheels 12 allow the user to push the entire device to move, and the device can be moved in any direction.

[0038] The oxygen supply tank 7 and the connecting pipe 8 are fixedly connected with a docking buckle 14 and a transfer buckle 13 at one end close to each other, and the transfer buckle 13 is fixedly connected with a joint 15 at one end close to the docking buckle 14. A pair of blocks 16 are fixedly connected to the inner wall of the docking buckle 14, and a pair of slide grooves 17 matching the blocks 16 are opened at the outer end of the joint 15. A slot 18 matching the blocks 16 is opened on the inner wall of the slide groove 17. An air bag 19 is fixedly connected to the inner wall of the slot 18, and an expansion bag 20 is fixedly connected to the inner wall of the slot 17, and the expansion bag 20 is connected to the air bag 19. The joint 15 is inserted into the middle of the docking buckle 14, so that a pair of blocks 16 slide into the slide groove 17 and rotate to make the blocks 16 slide into the slot 18. At the same time, the blocks 16 squeeze the air bag 19, so that the gas inside it enters the expansion bag 20 and bulges, thereby blocking the slide groove 17, which can not only prevent oxygen leakage, but also facilitate the disassembly and assembly of the oxygen supply tank 7 and the connecting pipe 8.

[0039] A pair of rubber blocks 21 are fixedly connected to the lower end of the adapter buckle 13, and the pair of rubber blocks 21 are located on the outside of the joint 15. A pair of grooves 22 matching the rubber blocks 21 are opened on the upper end of the docking buckle 14, and the pair of grooves 22 and the pair of blocks 16 are staggered. The rubber blocks 21 are inserted into the grooves 22, so that the adapter buckle 13 and the docking buckle 14 are not easy to fall off after docking and rotation.

[0040] Working principle:

[0041] After adjusting the lifting rod 3 to a suitable height, the user supports the top plate 4 to push and move it. When oxygen supply is needed, the mask is taken out of the storage box 5 and worn. During the movement, the pressing airbag 10 can be stepped on and pressured to allow the gas in the pressing airbag 10 to enter the oxygen absorption tube 92 and push the sealing plate 942 to open the middle of the built-in tube 941. Under the rebound force of the micro-spring 945, the limit block 943 can be driven to make the connecting plate 944 pull the sealing plate 942 to block the middle of the built-in tube 941 again to prevent the loss of oxygen in the oxygen supply tank 7. The user can also suck the sealing plate 942 out of the built-in tube 941 by inhaling hard, which can also make the gas in the middle of the built-in tube 941 open and flow, so that the elderly patient can get enough oxygen when moving and walking.

[0042] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0043] The present invention can adapt to users of different heights through the adjustable lifting rod 3, top plate 4 and adjustable height settings, thereby improving comfort and convenience. An oxygen supply system is arranged in the device, and the oxygen supply flow rate is controlled by pressing the airbag 10, thereby ensuring that the user can automatically or manually obtain sufficient oxygen as needed during walking, thereby effectively meeting the oxygen needs of elderly patients. The placement tube 6 and the fastening device can firmly fix oxygen tanks of different sizes to ensure the safety of oxygen supply. The three-way pipe 9, the one-way valve 93, and the oxygen control component 94 can accurately regulate the oxygen flow rate to avoid oxygen waste. The auxiliary plate 11 is arranged to facilitate the user's rest. The movable wheel 12 makes the overall device easy to push, which greatly improves the convenience of use. The transparent cover and sponge pad 64 effectively prevent the equipment and the mask from being contaminated or damaged by dust, thereby ensuring the hygiene and safety of long-term use.
