[0038] The rotating turntable 25 can drive the worm 24 to rotate, and the rotating worm 24 can drive the worm wheel 23 and the gear 22 to rotate, thereby driving the rack 21 to move up and down, thereby driving the fixing ring 19 to move up and down, and the arc-shaped curved plate 18 squeezes the oxygen cylinder 4 under the action of the spring to achieve the purpose of fixing the oxygen cylinder 4. At the same time, a buffer plate 5 is provided at the bottom of the oxygen cylinder 4, so that when the oxygen cylinder 4 is hit, it can be buffered to a certain extent in the horizontal and vertical directions, thereby protecting the oxygen cylinder 4.

[0039] like Figure 7 As shown, a disinfection component is provided on the top of the fixed component 2, and the disinfection component includes a protective cover 35 rotatably clamped on the top of the fixed ring 19, a telescopic rod is provided between the protective cover 35 and the fixed ring 19, a miniature ultraviolet sterilization lamp 36 is provided on the inner wall of the protective cover 35, and an annular sealing airbag 37 is provided at the bottom of the protective cover.

[0040] The output end of the oxygen cylinder 4 is generally exposed to the air. In order to improve the hygienic state of the oxygen cylinder 4, the output end of the oxygen cylinder 4 is first disinfected and sterilized using the disinfection component before connecting the oxygen absorption component; that is, the protective cover 35 can move up and down with the fixing ring 19, so that when the fixing component 2 fixes the oxygen cylinder 4, the output end of the oxygen cylinder 4 is located in the protective cover 35, and then the annular sealing airbag 37 is used to ensure that the protective cover 35 is sealed and connected to the oxygen cylinder 4, and then the ultraviolet sterilization lamp is turned on to sterilize the output end of the oxygen cylinder 4. After sterilization, the ultraviolet sterilization lamp 36 is turned off, the protective cover 35 is pulled up and rotated to expose the output end of the oxygen cylinder 4 to the air again, and the oxygen absorption component can be directly connected.

[0041] A forward and reverse motor 26 is provided on the top of the base 1. The output end of the forward and reverse motor 26 is provided with a bevel gear 27 rotatably connected to the base 1 through a rotating shaft. The bevel gear 27 is meshed with a bevel gear 28. The bevel gear 28 is provided on the side of the transition plate 2. The transition plate 2 is rotatably connected to the base 1 through the bevel gear 28. The side of the transition plate 2 is hinged with a plurality of baffles 29 through a torsion spring.

[0042] Start the forward and reverse motor 26, which drives the bevel gear 1 27 to rotate and the bevel gear 2 28 to rotate, thereby driving the transition plate 2 to rotate, so that the transition plate 2 can be tilted and one end can be in contact with the ground, and then the oxygen cylinder 4 can be pushed onto the transition plate 2, and then the forward and reverse motor 26 is started to drive the transition plate 2 to rotate in the opposite direction, so that the end of the transition plate 2 close to the base 1 is lower than the end of the transition plate 2 away from the base 1, and the oxygen cylinder 4 is driven to move to the top of the base 1 by its own gravity. The medical staff only needs to gently support the oxygen cylinder 4 to prevent it from tipping over, so that the oxygen cylinder 4 can be easily placed in the fixed component 1 on the top of the base 1, wherein the baffle 29 can prevent the oxygen cylinder 4 from sliding backwards. After use, the forward and reverse motor 26 is used to make the transition plate 2 perpendicular to the base, which can store the transition plate 2.

[0043] The oxygen detection assembly includes a control panel 30 fixed on the right side of the base 1, and a detection module is embedded in the control panel 30. The detection module of the control panel 30 is connected to a multi-way pipe 31 through a hose, and a solenoid valve is provided at the joint of the multi-way pipe 31. The multi-way pipe 31 is connected to four oxygen cylinders 4 and an oxygen absorption assembly. The oxygen absorption assembly includes a humidification bottle 32 connected to the multi-way pipe 31, and a flow meter 33 and a flow control valve are installed on the humidification bottle 32 through a connector. The humidification bottle 32 is also provided with a transfer sleeve 34 for connecting to a breathing mask. A pressure gauge is connected between the humidification bottle 32 and the multi-way pipe 31 through a hard pipe.

[0044] The solenoid valve in the multi-way tube 31 connected to the oxygen cylinder 4 is opened through the control panel 30, and the detection module embedded in the control panel 30 can detect the oxygen storage of the oxygen cylinder 4, so as to remind the medical staff whether the oxygen in the oxygen cylinder 4 meets the standard; the oxygen cylinder 4 that does not meet the standard is replaced, and the oxygen cylinder 4 that meets the standard is connected at the same time; and the oxygen supply is ensured to be uninterrupted when the oxygen cylinder 4 is replaced.

[0045] In addition, the base 1 is also provided with three drawers through the fixing plate, which can be used to place consumables such as hoses and breathing masks.

[0046] The specific usage of this embodiment is as follows:

[0047] When in use, the device is moved to the use area, and the oxygen storage of the oxygen cylinder 4 is first detected through the detection module in the control panel 30, and the dehumidification bottle 32 is connected with the oxygen cylinder 4 that meets the standard; then the oxygen cylinder 4 that does not meet the standard is replaced, ensuring uninterrupted oxygen supply when the oxygen cylinder 4 is replaced.

[0048] When replacing the oxygen cylinder 4, first disassemble the connected hose, rotate the turntable 25, drive the worm 24 to rotate, the rotating worm 24 drives the worm wheel 23 and the gear 22 to rotate, so that the rack 21 can be driven to move upward, thereby driving the fixing ring 19 to move upward, so that the oxygen cylinder 4 is separated from the fixing component 2; because the used oxygen cylinder 4 is lighter, the mounting seat 6 is flush with the top surface of the base 1 at this time, and the oxygen cylinder 4 is pulled to drive the mounting seat 6 to move, start the micro motor 10, and the micro motor 10 drives the threaded rod 11 to rotate. The rotating threaded rod 11 drives the adjusting block 2 12 to move along the threaded rod 11 toward the direction of the micro motor 10, and drives the fixing frame 7 to rotate. Under the cooperation of the slider 13, the rotating fixing frame 7 can drive the connecting rod 8 to rotate along the slider 13 in the direction away from the center of the fixing frame 7, thereby releasing the fixation of the bottom of the oxygen cylinder 4, and then the oxygen cylinder 4 can be removed.

[0049] Then, the forward and reverse motor 26 is started, and the forward and reverse motor 26 drives the bevel gear 27 to rotate while driving the bevel gear 22 to rotate, thereby driving the transition plate 2 to rotate, so that the transition plate 2 can be tilted and one end can be in contact with the ground, and then a new oxygen cylinder 4 is pushed onto the transition plate 2, and then the forward and reverse motor 26 is started again to drive the transition plate 2 to rotate in the opposite direction, so that the end of the transition plate 2 close to the base 1 is lower than the end of the transition plate 2 away from the base 1, and the oxygen cylinder 4 is driven to move to the top of the base 1 by its own gravity. The medical staff only needs to gently support the oxygen cylinder 4 to prevent it from tipping over.

[0050] Then, the bottom and the top of the oxygen cylinder 4 are fixed in sequence by the fixing assembly 1 and the fixing assembly 2, and the replacement of the oxygen cylinder 4 is completed, which is convenient and quick.

[0051] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
