Description

Technical Field

[0001] This application relates to the field of oxygen concentrator technology, and more specifically, to a portable medical oxygen concentrator. Background Technology

[0002] Existing oxygen concentrators are inconvenient to move and carry. In addition, because they are lightweight, they are prone to tipping over when subjected to vibration or impact, which can damage them.

[0003] In response, Chinese patent application number CN202121819789.5 discloses a portable medical oxygen concentrator. This design mainly uses pulleys to facilitate user movement and increase the portability of the device. When the device is moved to a suitable position, the sleeve and support rod are moved downward by shaking the handle, thereby supporting and fixing the device. The shock-absorbing springs eliminate vibrations during use, thus preventing tipping. The rubber pads effectively increase friction with the ground, preventing the device from tipping over.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this utility model discovered that the above-mentioned technology has at least the following technical problems:

[0005] 1. The pulleys do not have shock absorption capabilities, and they are prone to causing bumps when pushing the machine, which can damage the oxygen concentrator;

[0006] 2. When the threaded rod rotates, it replaces the pulley to support the oxygen concentrator body, playing a role in stabilizing the support. However, the support area is still very small and the stability is not high. Utility Model Content

[0007] To overcome the above deficiencies, this application provides a portable medical oxygen concentrator, which aims to improve the problems mentioned in the background art.

[0008] This application provides a portable medical oxygen concentrator, including an oxygen concentrator body and an L-shaped support rod. The oxygen concentrator body has sliding grooves on both sides, and the support rod has sliding columns at the upper and middle ends. The sidewall of the sliding groove has a through groove for the upper sliding column to pass through. A shock-absorbing rod is provided in the sliding groove and contacts the corresponding sliding column. The lower end of the support rod is provided with a caster wheel, and a sealing component is provided on the through groove.

[0009] In one specific implementation, a support plate is fixedly connected to the lower end of the oxygen generator body, and an adjustable support foot is provided at the lower end of the support plate.

[0010] In the above implementation process, the support plate is used to increase the support area, and the adjustable support feet are used to adjust the level of the support to prevent the oxygen concentrator body from shaking during use.

[0011] In one specific implementation, the caster wheels, when folded up, do not extend beyond the lower end of the adjustable feet.

[0012] In the above process, when the support rod is retracted, the casters are located below the oxygen generator body, and the adjustable support feet are used to support the ground instead of the casters.

[0013] In one specific implementation, four slides are provided, and the upper ends of two of the support rods on the same side are fixedly connected to connecting rods.

[0014] In the above process, one linkage drives the movement of two support rods, making operation simpler. Moreover, the linkage can also be used as a handle for easy lifting.

[0015] In one specific implementation, a stop block is fixedly connected to the telescopic end of the shock absorber rod, and the stop block is adapted to the sliding column.

[0016] In the above implementation process, the abutment has a concave surface with an arc for fitting with the sliding column, and the abutment slides in the groove, which can prevent the front end of the shock absorber from being subjected to radial torque.

[0017] In one specific implementation, the sealing component includes an insert plate that is inserted into the groove, and a pull ring is fixedly connected to the outer end of the insert plate.

[0018] In the above implementation process, the insert plate is inserted into the through hole on the slide groove to prevent the slide column from coming out of the slide groove when sliding.

[0019] In one specific implementation, a limiting plate is fixedly connected to the insert plate, and the limiting plate is movably pressed against the slide groove.

[0020] In one specific implementation, the limiting plate is magnetically connected to the slide groove.

[0021] In the above implementation process, the limiting plate is used to limit the position of the insert plate and is magnetically attached to the slide groove for easy operation.

[0022] Compared with the prior art, the beneficial effects of this application are: by using the two sliding columns on the L-shaped support rod to slide in combination with the sliding groove, the support rod can be vertically retracted and in an outward support state, which expands the support area and improves stability. Furthermore, both states can utilize the shock-absorbing rod for shock absorption, effectively reducing the bumps when the oxygen concentrator moves. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0030] Please see Figures 1-4 This application provides a portable medical oxygen concentrator, including an oxygen concentrator body 10 and an L-shaped support rod 20. The oxygen concentrator body 10 has sliding grooves 30 on both sides. The support rod 20 has sliding columns 40 at its upper and middle ends. The sidewalls of the sliding grooves 30 have through slots for the upper sliding columns 40 to pass through. A shock-absorbing rod 50 is installed inside the sliding groove 30, contacting the corresponding sliding column 40. A caster wheel 60 is installed at the lower end of the support rod 20, and a sealing element 70 is installed on the through slot. By utilizing the sliding interaction between the two sliding columns 40 on the L-shaped support rod 20 and the sliding grooves 30, the support rod 20 can be vertically retracted or in an outward-facing support state, increasing the support area and improving stability. Furthermore, the shock-absorbing rod 50 can be used for shock absorption in both states, effectively reducing the bumps during movement of the oxygen concentrator body 10.

[0031] Please see Figures 1-4The lower end of the oxygen concentrator body 10 is fixedly connected to a support plate 80, and an adjustable support foot 90 is provided at the lower end of the support plate 80. The support plate 80 is used to increase the support area, and the adjustable support foot 90 is used to adjust the level of the support to prevent the oxygen concentrator body 10 from shaking during use.

[0032] Please see Figures 1-4 When the caster wheel 60 is folded up, it does not extend beyond the lower end of the adjustable support leg 90. When the support rod 20 is folded up, the caster wheel 60 is located below the oxygen concentrator body 10, and the adjustable support leg 90 supports the ground instead of the caster wheel 60.

[0033] Please see Figures 1-4 The slide 30 has four sections, and the upper ends of the two support rods 20 on the same side are fixedly connected to the connecting rods 100. One connecting rod 100 drives the two support rods 20 to move, making operation simpler. In addition, the connecting rod 100 can also be used as a handle for easy lifting.

[0034] Please see Figures 1-4 A stop block 110 is fixedly connected to the telescopic end of the shock absorber 50, and the stop block 110 is adapted to the slide column 40. The stop block 110 has a concave surface with an arc for fitting with the slide column 40, and the stop block 110 slides in the slide groove 30, which can prevent the front end of the shock absorber 50 from being subjected to radial torque.

[0035] Please see Figures 1-4 The sealing component 70 includes an insert plate 71, which is inserted into the slide groove 30. A pull ring 72 is fixedly connected to the outer end of the insert plate 71. The insert plate 71 is inserted into the through hole on the slide groove 30 to prevent the slide column 40 from coming out of the slide groove 30 when sliding.

[0036] Please see Figures 1-4 A limiting plate 73 is fixedly connected to the insert plate 71, and the limiting plate 73 is movably pressed against the slide groove 30. The limiting plate 73 is magnetically connected to the slide groove 30. The limiting plate 73 is used to limit the position of the insert plate 71, and is magnetically attached to the slide groove 30 for easy operation.

[0037] The working principle of this portable medical oxygen concentrator is as follows: When stored, the middle sliding column 40 slides upward while the upper sliding column 40 is located outside the slide groove 30. The casters 60 are located below the oxygen concentrator body 10, and the adjustable support feet 90 replace the casters 60 to support the ground. On the other hand, the connecting rod 100 forms a handle. When the handle is pulled to move the oxygen concentrator body 10, the middle sliding column 40 abuts against the shock-absorbing rod 50, which plays a role in shock absorption. When pushing, the insert plate 71 is pulled open, and the upper sliding column 40 is slid from the through groove into the slide groove 30. Slide upwards to abut against the shock absorber 50. At this time, the lower end of the support rod 20 is supported in an eight-shape. The caster wheel 60 supports the ground, which not only expands the support area but also has a shock absorption effect, making it easy to push stably. In summary, by using the two sliding columns 40 on the L-shaped support rod 20 to slide in conjunction with the sliding groove 30, the support rod 20 can be vertically retracted and in an outward eight-shape support state, which expands the support area and improves stability. In addition, the shock absorber 50 can be used to absorb shock in both states, effectively reducing the bumps when the oxygen concentrator body 10 moves.
