Description

Technical Field

[0001] The present invention relates to the technical field of oxygenation equipment, in particular to a mobile oxygenation equipment for shelters and field hospitals. Background Art

[0002] Currently, hospitals worldwide typically supply oxygen by vaporizing liquid oxygen stored in on-site tanks and then delivering it to wards via pipelines, or by centrally distributing pressure vessels from gas filling plants. However, for oxygen inhalation locations (outside of wards) or smaller hospitals without pipelines, oxygen supply relies on conventional 40L steel cylinders weighing 60 kg and standing 1.4 meters tall.

[0003] As essential essential medicines for hospitals, pressure vessels often face the challenge of relying on specialized hazardous materials vehicles for centralized distribution, as well as the risk of accidents during intra-hospital transportation. In particular, to address the shortage of isolation beds caused by the sudden outbreak of COVID-19, makeshift hospitals (FMCS) of varying sizes were established around the world during the pandemic. However, since these hospitals are located outdoors or in temporary rented spaces, they lack the piped oxygen supply systems of conventional hospitals. Even when gas cylinders are centrally delivered to the hospitals, they ultimately have to be transported to designated locations within the hospitals by hospital personnel (who are not specialized in gas handling) to prevent cross-contamination. This presents inherent transportation safety concerns and the inability to ensure simultaneous oxygen delivery to large numbers of patients. For oxygen cylinder factories, transporting hazardous materials (full and empty oxygen cylinders) between hospitals presents the traditional challenges of road safety hazards and road closures caused by natural disasters.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0036] Example

[0037] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0038] like Figure 1-11As shown, a mobile oxygenation device for a shelter and a field hospital includes a support base 1, a connecting plate 2, a connecting slot 3 and a rotating shaft 4. The front and rear sides of the support base 1 are fixedly provided with a connecting plate 2, the interior of the connecting plate 2 is provided with a connecting slot 3, the interior of the connecting slot 3 is movably provided with a rotating shaft 4, the surface of the rotating shaft 4 is rotatably connected to the shelter 5, the left and right sides of the support base 1 are fixedly provided with an electric push rod 6, the top of the electric push rod 6 is fixedly provided with a fixing plate 7, the top of the fixing plate 7 is fixedly provided with a rubber pad 8, and the bottom end of the rubber pad 8 is fixedly provided with a connecting shaft 9. A bottom plate 10 is provided below the connecting shaft 9. The surface of the bottom plate 10 is provided with a beveled surface. A fixing rod 12 is fixedly provided on the side of the bottom plate 10. Slide grooves 11 are provided on the left and right sides of the support seat 1. A first spring 13 is sleeved on the outer side of the fixing rod 12. The head and tail ends of the first spring 13 are respectively connected to the fixing rod 12 and the support seat 1. A middle plate 14 is fixedly provided in the middle of the cabin 5. The oxygen storage equipment is stored in the cabin to reduce the transportation link of dangerous goods from the canning factory to the hospital and prevent cross infection between hospitals.

[0039] In this example, the cabin 5 forms a rotating structure with the connecting plate 2 through the connecting groove 3 and the rotating shaft 4. The connecting groove 3 is arc-shaped on the connecting plate 2. There is a gap between the cabin 5 and the support seat 1, so that the cabin 5 can always remain flush with the ground when the vehicle moves to a bumpy road section, thereby improving the stability of the device.

[0040] In this example, the rubber pads 8 and the connecting shafts 9 are evenly spaced on the fixed plate 7. The rubber pads 8 are in the shape of a hemisphere. The base plate 10 forms a telescopic structure with the support seat 1 through the connecting shaft 9. The base plate 10 forms an elastic structure with the support seat 1 through the fixing rod 12 and the first spring 13. The telescopic structure on the device enables the device to automatically extend the base plate 10 during the process of removing the internal oxygen storage device, thereby improving the use effect of the device.

[0041] In this example, a second spring 15 is fixedly connected to the surface of the middle plate 14, a buffer plate 16 is fixedly provided at the front end of the second spring 15, and a bracket 17 is provided on the side of the buffer plate 16. The bracket 17 is used to store the oxygen storage equipment, and the second spring 15 and the buffer plate 16 ensure that the bracket 17 is stably placed.

[0042] In this example, a rear plate 18 is slidably installed on the rear side of the bracket 17, and a front plate 20 is slidably installed on the front end of the bracket 17. Damping pads 21 are fixedly installed inside the front plate 20 and the rear plate 18. The damping pads 21 can have a shock-absorbing effect. A guide rod 19 is fitted inside the damping pad 21. The guide rod 19 enables the rear plate 18 to move straight back and forth, thereby improving the stability of the device.

[0043] In this example, a screw rod 27 is threadedly installed on the left side of the rear plate 18, and a limit block 30 is installed on the end bearing of the screw rod 27. The connection between the limit block 30 and the bracket 17 is a sliding connection. An adjustment groove 29 is provided on the rear side of the bracket 17. The width of the adjustment groove 29 is greater than the width of the rear plate 18. The rear plate 18 forms a telescopic structure with the bracket 17 through the adjustment groove 29 and the screw rod 27. The telescopic structure enables the device to stably fix and clamp the oxygen storage equipment.

[0044] In this example, an oxygen cylinder 25 is placed between the guide rod 19 and the adjacent guide rod 19. The oxygen cylinder 25 is made of carbon fiber. A base 24 is provided on the rear side of the oxygen cylinder 25. A pressure reducer 26 is installed on the front end of the oxygen cylinder 25 to ensure the strength of the bottle body and improve the safety of the device during use.

[0045] In this example, the connection between the front plate 20 and the screw 27 is a rotational connection, and docking rods 28 are fixedly provided between the front plate 20 and the adjacent front plate 20 and between the rear plate 18 and the adjacent rear plate 18. The docking rods 28 enable the device to synchronously move the front plate 20 and the rear plate 18 on the upper and lower sides, thereby improving the convenience of using the device.

[0046] In this example, a second connecting cover 23 is fixedly provided on the surface of the front plate 20, and a first connecting cover 22 is fixedly provided on the surface of the rear plate 18. The first connecting cover 22 and the second connecting cover 23 are both bowl-shaped, and there is a one-to-one correspondence between the first connecting cover 22 and the second connecting cover 23. The bottle body is stably fixed by the first connecting cover 22 and the second connecting cover 23, thereby improving the stability of the device.

[0047] It should be noted that the present invention is a mobile oxygenation device for shelters and field hospitals. First, Figure 1-3 As shown, when encountering a bumpy road section, the support base 1 will be skewed. The rotating shaft 4 installed on the cabin 5 makes it possible to change the angle between the support base 1 and the connecting plate 2 without causing adverse effects on the cabin 5. The connecting plate 2 rotates on the outside of the cabin 5 through the connecting groove 3 and the rotating shaft 4. At this time, the cabin 5 is Figure 2 The state changes to Figure 3 In the state of the cabin 5, the cabin 5 is always in a horizontal state, thereby ensuring that the bracket 17 and the oxygen cylinder 25 in the cabin 5 will not tilt or fall;

[0048] like Figure 1 and Figure 4-11As shown, when the device is in use, the second spring 15 and the buffer plate 16 on the middle plate 14 can also be used to support the bracket 17, so that the bracket 17 can play a buffering role when shaking, thereby protecting the oxygen cylinder 25 on the surface of the bracket 17. When the oxygen cylinder 25 shakes, since the oxygen cylinder 25 is placed between two adjacent guide rods 19, the damping pads 21 on the rear plate 18 and the front plate 20 at the head and tail ends of the guide rod 19 enable the oxygen cylinder 25 to squeeze the guide rod 19, thereby preventing the oxygen cylinder 25 from hitting the guide rod 19 and causing damage to the bottle body; after the oxygen cylinder 25 is placed between the two adjacent guide rods 19, the screws 27 on both sides of the device are rotated, so that the rear plate 18 moves straight back and forth under the limiting action of the adjustment groove 29, thereby making the first connecting cover 22 and the second connecting cover 23 approach each other and clamp the oxygen cylinder 25, completing the oxygen To fix the gas cylinder 25, the docking rod 28 connects the two adjacent rear plates 18 and the two adjacent front plates 20 to each other, so that more oxygen cylinders 25 can be stored. When the bracket 17 inside the device is moved out, the electric push rod 6 on one side is extended and the electric push rod 6 on the other side is shortened, so that the cabin 5 is tilted as a whole. The shortened electric push rod 6 is pressed against the beveled surface of the bottom plate 10 in the slide groove 11 through the connecting shaft 9 under the rubber pad 8, so that the bottom plate 10 automatically moves outward, and the first spring 13 on the fixing rod 12 is stretched. At this time, the edge of the support seat 1 can make the bracket 17 slide smoothly, completing the stable removal of the bracket 17. The limit block 30 ensures that the screw 27 can move vertically up and down with the rear plate 18, and the bottom bracket 24 ensures that the oxygen cylinder 25 can be stably supported when placed, thereby playing an explosion-proof function.

[0049] To enable canned oxygen storage at various locations, including temporary hospitals, the present invention utilizes a container that is easily transported by truck or lifted by helicopter. The container houses a small gas filling system capable of storing a large number of oxygen cylinders 25 in corresponding quantities. The filling system comprises a liquid oxygen pump assembly, a vaporizer, a control cabinet, a filling station, inter-equipment piping, various components and detection devices, and the oxygen cylinders 25. The oxygen cylinders 25 are portable composites made of a dense aluminum liner and high-strength carbon fiber (weighing 6 kg, 0.7 m tall, and with a capacity of 10 L).

[0050] This canning system utilizes the hospital's existing liquid storage tanks (CE) or temporarily deployed mobile small liquid storage tanks (LGC) during on-site production. An automatic control system forcibly pumps liquid oxygen into the vaporizer. During the expansion process from liquid to gas, the gaseous oxygen is effectively and safely filled into medical or firefighting breathing oxygen cylinders 25 placed on the canning rack through pipelines, various components, and detection devices.

[0051] In order to prevent the oxygen cylinders 25 from heating up as a whole due to excessive filling speed, a variable frequency motor is installed in the pump body of the present invention. The pump body is integrated with the pump body to control the overall pressure increase speed of the filling to 0.4-0.8 MPa / min and the maximum temperature to a safe range of below 40 degrees Celsius based on the actual number of oxygen cylinders 25 filled and the measured pressure and temperature of each pipeline.

[0052] To prevent the traditional production problems of overfilling or underfilling, the control system of this invention is equipped with a standard gas cylinder and a dedicated scale. By precalculating and setting the mass of the gas to control the pump switch to achieve the required filling pressure, the actual filling pressure error caused by ambient temperature and human factors is eliminated.

[0053] To overcome the traditional practice of circulating oxygen cylinders 25 from filling plants among hospitals, and to prevent cross-infection between hospitals and the potential dangers of transporting conventional steel cylinders within and outside hospitals, the present invention utilizes portable carbon fiber oxygen cylinders 25 equipped with a data storage chip. Before and after filling, a dedicated handheld reader transmits various oxygen cylinder information to an automated control system in a control cabinet or other information processor. This determines the filling pressure increase rate based on the number of cylinders produced, and provides traceable analysis of each batch of oxygen cylinders. This also facilitates the management of each hospital's own oxygen cylinders 25. Due to its unique portability, lightweight design, high efficiency (at least 5 MPa higher filling pressure than conventional steel cylinders), and safety (no fragmentation when exploded, unlike conventional steel cylinders), this oxygen cylinder 25 is suitable for safe and reliable transport by hospital staff, addressing the issue of oxygen supply in areas without pipelines.

[0054] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
