[0002] The constant pressure insulation box for infusion bags is a device specially designed for constant temperature storage of infusion bags in medical institutions. It mainly ensures that the liquid in the infusion bag maintains a constant temperature during transportation and use through constant temperature storage, thereby maintaining the stability and safety of the liquid. In addition to the constant temperature function, some advanced constant pressure insulation boxes also have a constant pressure control function to ensure that in special circumstances, such as bumps during transportation, the internal pressure of the infusion bag remains stable to prevent liquid leakage or excessive pressure.

[0003] Chinese patent document (CN116808362A) discloses a phase-change energy storage infusion bag temperature control box, which proposes a phase-change energy storage infusion bag temperature control box in the specification, belonging to the field of medical equipment technology, including an insulation box and a phase-change energy storage assembly; the phase-change energy storage assembly includes an enhanced heat transfer component, a phase-change energy storage medium and a thermal management control system; the enhanced heat transfer component is welded by a plurality of heat-conducting ribs and a heating empty tube, the heating empty tube includes a central heating empty tube and four peripheral heating empty tubes, and the phase-change energy storage medium is arranged at intervals in a plurality of Between the heat-conducting ribs; the thermal management control system includes a heating device and an electronic control device. The present invention utilizes phase change heat storage technology with the advantages of constant temperature and high heat storage density, and combines the use of ribs to increase the heat transfer area to enhance heat transfer measures, which provides a solution to the incoordination between heat supply and demand during patient infusion. The temperature control box is also provided with a peripheral heat transfer cavity that can be used by four people, which can solve the need for medical staff to share infusion for multiple patients. However, in actual use, there is still a situation where internal pressure and heat leakage occur when it is opened, resulting in a waste of resources.

[0004] Currently, the constant pressure insulation box used for infusion bags has strict requirements for maintaining internal temperature and pressure. However, whenever the box needs to be opened to take out the infusion bag, a large amount of heat and air pressure will often leak. This leakage not only leads to energy waste, but also affects the ability of the insulation box to maintain a constant state. It is difficult for the existing constant pressure insulation box to effectively recover heat and air pressure when it is opened, which undoubtedly aggravates the excessive consumption and waste of resources. In view of this, we propose a constant pressure insulation box for infusion bags. Summary of the invention

[0026] A method for using a constant pressure incubator for an infusion bag comprises the following steps:

[0027] S1. When in use, the cover needs to be pulled up horizontally so that the cover drives the insulation bucket to move upward, and then the infusion bags to be stored are assembled on the hooks in sequence, and then they can be stored and transported;

[0028] S2. When the cover is pulled upward to drive the insulation bucket and the extrusion block to move upward, the extrusion block will gradually separate from the docking block, causing the docking block to lose extrusion and move upward under the action of the elastic force of the elastic telescopic rod. At this time, the fan blades no longer contact the adjusting block during rotation, so that the coil spring drives the rotating shaft to rotate while adjusting the angle of the fan blades, thereby extracting the gas above the sealing cover, in the branch pipe and the exhaust pipe and storing it under the chassis, thereby realizing heat and air pressure recovery. When the cover is moved downward to allow the insulation bucket to enter the sealing cover and the extrusion block pushes the docking block to move downward, the fan blades will change their angle due to contact with the adjusting block, thereby extracting the gas below and transporting it upward.

[0029] S2.1. When the cover is pulled upward to drive the insulation barrel and the extrusion block to move upward, the extrusion block will gradually separate from the docking block, causing the docking block to lose its extrusion and move upward under the action of the elastic force of the elastic telescopic rod. At this time, the fan blades no longer contact the adjustment block during rotation, so that the coil spring drives the rotating shaft to rotate while adjusting the angle of the fan blades, thereby extracting the air above the sealing cover. At the same time, the gas in the branch pipe and the exhaust pipe will be extracted through the sealing cover. When the gas in the exhaust pipe is extracted, the outside gas will quickly enter along the air inlet groove on the guide plate;

[0030] S2.2. When the cover plate is moved down so that the insulation barrel enters the sealing cover and the extrusion block pushes the docking block downward, the angle of the fan blades will change due to contact with the adjustment block, thereby extracting the gas below and transporting it upward. When the gas is discharged, it will first enter the air inlet groove in the guide plate and will be blocked by the resistance plate after entering, so that the gas enters the exhaust groove in large quantities. The exhaust groove is set in an arc shape, which increases the path for gas circulation, thereby quickly increasing the temperature of the guide plate, heat conduction plate and heat sink, thereby increasing the temperature inside the device as a whole.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention designs a docking device, an adjusting block and an extruding block. When the cover plate is pulled upward to drive the insulation barrel and the extruding block to move upward, the extruding block will gradually separate from the docking block, so that the docking block loses extrusion and moves upward under the action of the elastic force of the elastic telescopic rod. At this time, the fan blade no longer contacts the adjusting block during rotation, so that the coil spring drives the rotating shaft to rotate while adjusting the angle of the fan blade, thereby extracting the gas above the sealing cover, in the branch pipe and the air outlet pipe and storing it under the chassis, thereby realizing heat and air pressure recovery. When the cover plate is moved downward to make the insulation barrel enter the sealing cover and the extruding block pushes the docking block to move downward, the fan blade will change its angle due to contact with the adjusting block, thereby extracting the gas below and transporting it upward, so that when the device is opened and the infusion bag is stored therein, the air and heat inside the device can be automatically extracted and stored, and when the storage is completed and transported again, the device can automatically discharge the gas and heat stored inside the device, thereby realizing air and heat resource recycling and reuse, avoiding the leakage of internal heat and air when the device is opened, and reducing excessive consumption and waste of resources.

[0033] 2. The present invention also designs a flow guide component and a control component. When the cover plate is pulled upward to drive the heat preservation barrel and the extrusion block to move upward, the extrusion block will gradually separate from the docking block, causing the docking block to lose extrusion and move upward under the action of the elastic force of the elastic telescopic rod. At this time, the fan blades no longer contact the adjustment block during rotation, so that the coil spring drives the rotating shaft to rotate while adjusting the angle of the fan blades, thereby extracting air above the sealing cover. At the same time, the gas in the branch pipe and the exhaust pipe will be extracted through the sealing cover. When the gas in the exhaust pipe is extracted, the outside gas will quickly enter along the air inlet groove on the guide plate. Since the air inlet groove is vertically arranged, the efficiency of air entry is guaranteed, which ensures that the device can extract air with the shortest stroke in the process of recovering heat and air, thereby preventing the occurrence of resource waste to the greatest extent.

[0034] 3. The present invention also designs a placement component and a control component. When the cover plate is moved down so that the insulation barrel enters the sealing cover and the extrusion block pushes the docking block to move down, the angle of the fan blade will change due to contact with the adjustment block, thereby extracting the gas below and transporting it upward. When the gas is discharged, it will first enter the air intake groove in the guide plate, and will be blocked by the resistance plate after entering, so that the gas enters the exhaust groove in large quantities. The exhaust groove is arranged in an arc shape, thereby increasing the path of the gas circulation, and then quickly increasing the temperature of the guide plate, the heat conduction plate and the heat sink, thereby increasing the temperature inside the device as a whole, so that the device can quickly increase its internal temperature after assembly. The use of the device only needs to be assembled and disassembled in conjunction with the necessary placement components, thereby reducing the difficulty of using the device and ensuring the constant pressure and insulation effect of the infusion bag.

The telescopic rod 205-202 moves upward under the action of the elastic force. At this time, the fan blade 205-3 no longer contacts the adjustment block 205-4 during rotation, so that the coil spring 205-206 drives the rotating shaft 205-205 to rotate while adjusting the angle of the fan blade 205-3, thereby extracting the gas above the sealing cover 205-1, the branch pipe 207 and the outlet pipe 206 and storing it under the chassis 201, realizing the recovery of heat and air pressure, and moving the cover plate 2010-1 downward so that the insulation bucket 2010-2 enters the sealing cover 205-1 and the extrusion block 2010-4 pushes the docking block 2 When 05-203 moves downward, the angle of the fan blade 205-3 will change due to the contact with the adjustment block 205-4, thereby extracting the gas below and transporting it upward, so that when the device is turned on and the infusion bag is stored inside, it can automatically extract the internal air and heat and preserve them, and when the storage is completed and transported again, the device can automatically discharge the gas and heat stored inside, thereby realizing the recycling and reuse of air and heat resources, avoiding the leakage of internal heat and air when the device is turned on, and reducing excessive consumption and waste of resources.

[0060] By setting the rubber block 208-4, it can be ensured that when the elastic telescopic sleeve 208-3 is vertically extended and contracted, the rubber block 208-4 can ensure the connection effect between the elastic telescopic sleeve 208-3 and the sealing plate 209-1 by its own deformation, and ensure the regulating effect of the elastic telescopic sleeve 208-3 on the two sealing plates 209-1.

[0061] Working principle: This embodiment provides a constant pressure insulation box for infusion bags. When in use, the cover plate 2010-1 needs to be pulled up horizontally, so that the cover plate 2010-1 drives the insulation bucket 2010-2 to move up, and then the infusion bags to be stored are assembled on the hooks 2010-5 in sequence, so that they can be stored and transported;

[0062] When the cover plate 2010-1 is pulled upwards to drive the heat preservation barrel 2010-2 and the extrusion block 2010-4 to move upwards, the extrusion block 2010-4 will gradually separate from the docking block 205-203, so that the docking block 205-203 loses the extrusion and moves upwards under the elastic force of the elastic telescopic rod 205-202. At this time, the fan blade 205-3 no longer contacts the adjustment block 205-4 during rotation, so that the coil spring 205-206 drives the rotating shaft 205-205 to rotate while adjusting the fan blade 205-3. 05-3, thereby extracting the gas above the sealing cover 205-1, the branch pipe 207 and the exhaust pipe 206 and storing them under the bottom plate 201, realizing the recovery of heat and air pressure. When the cover plate 2010-1 is moved down to allow the insulation barrel 2010-2 to enter the sealing cover 205-1 and the extrusion block 2010-4 pushes the docking block 205-203 to move down, the fan blade 205-3 will change its angle due to the contact with the adjustment block 205-4, thereby extracting the gas below and transporting it upward.

[0063] When the cover plate 2010-1 is pulled upwards, thereby driving the heat preservation barrel 2010-2 and the extrusion block 2010-4 to move upwards, the extrusion block 2010-4 will gradually separate from the docking block 205-203, so that the docking block 205-203 loses the extrusion and moves upwards under the elastic force of the elastic telescopic rod 205-202. At this time, the fan blade 205-3 no longer contacts the adjustment block 205-4 during rotation, so that the coil spring 205-206 drives the rotating shaft 205-205 to rotate while adjusting the angle of the fan blade 205-3, thereby extracting the air above the sealing cover 205-1. At the same time, the gas in the branch pipe 207 and the exhaust pipe 206 will be extracted through the sealing cover 205-1. When the gas in the exhaust pipe 206 is extracted, the outside gas will quickly enter along the air inlet groove 204-2 on the guide plate 204-1.

[0064] When the cover plate 2010-1 is moved downward so that the insulation barrel 2010-2 enters the sealing cover 205-1 and the extrusion block 2010-4 pushes the docking block 205-203 downward, the angle of the fan blade 205-3 will change due to the contact with the adjustment block 205-4, thereby extracting the gas below and transporting it upward, and when the gas is discharged, it will first enter the air intake groove 204-2 in the guide plate 204-1, and after entering, it will be blocked by the resistance plate 204-4, so that the gas enters the exhaust groove 204-3 in large quantities, and the exhaust groove 204-3 is arranged in an arc shape, thereby increasing the path for gas circulation, thereby quickly increasing the temperature of the guide plate 204-1, the heat conduction plate 203-1 and the heat sink 203-2, thereby increasing the temperature inside the device as a whole.
