[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a mobile medical oxygen generator includes a body 1. A compressor 8 is disposed between the inner walls of the body 1. A filter box 9 is fixedly connected to one side of the compressor 8 and between the inner walls of the body 1. The suction end of the compressor 8 extends to the outside of the body 1, and the output end of the compressor 8 communicates with the interior of the filter box 9. A support plate 12 is fixedly connected between the inner walls of the body 1. Two molecular sieves 13 are fixedly connected to one side of the support plate 12, and two oxygen storage tanks 14 are fixedly connected to the top of the support plate 12. A humidification box 2 is fixedly connected to one side of the body 1. A water inlet 4 is opened at the top of the humidification box 2, and an air outlet 3 is opened on one side of the humidification box 2. A U-shaped base 6 is slidably connected to the bottom of the body 1. A lifting assembly is provided on the side, which is used to move the U-shaped base 6. The bottom of the U-shaped base 6 is provided with four casters 7. A gas guide pipe 11 is provided between the two molecular sieves 13 and the filter box 9. The two gas guide pipes 11 are respectively connected to the interior of the two molecular sieves 13 and are also connected to the interior of the filter box 9. A solenoid valve 15 is provided on the outside of the two gas guide pipes 11. An oxygen supply pipe 19 is provided between the two oxygen storage tanks 14 and the two molecular sieves 13. The two oxygen supply pipes 19 are respectively connected to the interior of the two oxygen storage tanks 14 and the two molecular sieves 13. The output end of the two oxygen storage tanks 14 is connected to the interior of the humidification box 2. A sliding groove 18 is provided on one side of the body 1. A filter plate 10 is slidably connected between the inner walls of the sliding groove 18.
[0023] When using the medical oxygen concentrator, the machine body 1 is first moved to the usage area using the four casters 7 (a power supply carrier is located on the outside of the machine body 1 to provide power to the controller and electrical equipment). Then, according to usage needs, the U-shaped base 6 is moved at the bottom of the machine body 1 by the lifting assembly, thereby adjusting the usage height of the machine body 1. Subsequently, water is added to the humidification tank 2 through the water inlet 4. Then, the compressor 8 is started using the controller. The compressor 8 compresses and delivers air to the filter box 9, and the air passes through the filter plate 10 inside the slide 18 (specifically made of non-woven fabric material to ensure the filtration performance and air permeability of the filter plate 10). The air is filtered to remove impurities. Then, a solenoid valve 15 is used to open the corresponding air pipe 11, and the air is introduced into the corresponding molecular sieve 13 (specifically made of zeolite material, with a regular crystal lattice structure and microporous network, and an internal pressure sensor for monitoring pressure). This pressurizes the molecular sieve 13 and adsorbs nitrogen from the air. The oxygen is then transported along the corresponding oxygen supply pipe 19 to the corresponding oxygen storage tank 14 on the support plate 12 (both oxygen storage tanks 14 are equipped with oxygen concentration sensors to ensure that the oxygen concentration meets the requirements for use). Finally, the oxygen enters the humidification box 2 for humidification and is output for use through the air outlet 3.
[0024] When the internal pressure of the molecular sieve 13 is too high, the corresponding air supply can be reduced by controlling the corresponding air delivery pipe 11 through the corresponding solenoid valve 15. Then, the corresponding air delivery pipe 11 can be opened by another solenoid valve 15. Oxygen production and delivery operations are then carried out through the corresponding molecular sieve 13, oxygen supply pipe 19 and oxygen storage tank 14 for use, thereby achieving continuous oxygen production.
[0025] After the patient finishes receiving oxygen, the two solenoid valves 15 can be used to simultaneously close the two air delivery tubes 11, thereby reducing the pressure inside the two molecular sieves 13 and releasing nitrogen gas. The nitrogen gas is then transported to the interior of the humidification box 2 through the two oxygen supply tubes 19 and the two oxygen storage tanks 14, and finally discharged through the air outlet 3, thus improving the effectiveness of the medical oxygen generator.
[0026] like Figures 1-5 As shown, the lifting assembly includes a lifting groove 16 and a guide groove 20. The lifting groove 16 and the guide groove 20 are respectively opened on both sides of the body 1. A threaded rod 17 is rotatably connected between the inner walls of the lifting groove 16. A lifting block 22 is threadedly connected to the outer side of the threaded rod 17. One side of the lifting block 22 is fixedly connected to the U-shaped base 6. A guide rod 21 is fixedly connected between the inner walls of the guide groove 20. A guide block 23 is slidably connected to the outer side of the guide rod 21. One side of the guide block 23 is fixedly connected to the U-shaped base 6. A lifting motor 5 is fixedly installed on the top of the body 1. The output end of the lifting motor 5 extends into the interior of the lifting groove 16 and is fixedly connected to the threaded rod 17.
[0027] The lifting motor 5 drives the threaded rod 17 to rotate between the inner walls of the lifting groove 16, thereby moving the lifting block 22. At the same time, the guide block 23, which moves on the guide rod 21 inside the guide groove 20, drives the U-shaped base 6 to move between the inner walls of the body 1, thereby improving the adjustment flexibility of the medical oxygen concentrator.
[0028] This utility model provides a portable medical oxygen concentrator. Its specific working principle is as follows: When using the medical oxygen concentrator, the machine body 1 is first moved to the usage area using four wheels 7 (a power carrier is provided on the outside of the machine body 1 to provide power to the controller and electrical equipment). Then, according to usage needs, the controller starts the lifting motor 5. The lifting motor 5 drives the threaded rod 17 to rotate between the inner walls of the lifting groove 16, thereby moving the lifting block 22. Simultaneously, the guide block 23, which moves on the guide rod 21 inside the guide groove 20, moves the U-shaped base 6 between the inner walls of the machine body 1. The machine body 1 is adjusted to change its height. Water is then added to the humidification chamber 2 through the water inlet 4. The compressor 8 then compresses and delivers air to the filter chamber 9, where it is filtered by the filter plate 10 inside the slide 18. Next, a solenoid valve 15 opens the corresponding air pipe 11, which then introduces air into the corresponding molecular sieve 13. This pressurizes the molecular sieve 13 and adsorbs nitrogen from the air. Oxygen is delivered along the corresponding oxygen supply pipe 19 to the corresponding oxygen storage tank 14 on the support plate 12. Finally, the oxygen enters the humidification chamber 2 for humidification and is then output through the air outlet 3.
[0029] When the internal pressure of the molecular sieve 13 is too high, the corresponding air supply can be reduced by controlling the corresponding air delivery pipe 11 through the corresponding solenoid valve 15. Then, the corresponding air delivery pipe 11 can be opened by another solenoid valve 15. Oxygen production and delivery operations are then carried out through the corresponding molecular sieve 13, oxygen supply pipe 19 and oxygen storage tank 14 for use, thereby achieving continuous oxygen production.
[0030] After the patient finishes receiving oxygen, the two air delivery tubes 11 can be closed simultaneously through the two solenoid valves 15, which will reduce the pressure inside the two molecular sieves 13 and release nitrogen gas. The nitrogen gas is then transported to the interior of the humidification box 2 through the two oxygen supply tubes 19 and the two oxygen storage tanks 14, and finally discharged through the air outlet 3, thus completing the use of the medical oxygen generator.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
