[0002] Mannitol is a six-carbon sugar alcohol with a chemical formula of C6H 14 O6 is a white crystalline powder or granules with a sweet taste and high osmotic pressure. It is mainly used clinically to reduce intracranial pressure and intraocular pressure. It can also be used as an osmotic diuretic. By increasing the plasma osmotic pressure, the water in the interstitial fluid is transferred to the plasma, producing a dehydrating effect, thereby reducing cerebral edema and lowering intraocular pressure. It is widely used in neurosurgery, ophthalmology and other fields. In addition, it can also be used as a sweetener in the food industry.

[0003] The use of mannitol in the field is mainly due to its high osmotic dehydration effect. For example, in emergency situations such as craniocerebral injury, mannitol can quickly increase plasma osmotic pressure, transfer interstitial fluid water to plasma, thereby reducing intracranial pressure and buying time for treatment for patients. However, existing mannitol has shortcomings in field applications. It is easy to crystallize at low temperatures and cannot maintain a liquid state. This means that when used in a low-temperature environment in the field, it must be heated and dissolved first, otherwise it cannot be used directly.

A field mannitol liquid maintenance device based on a chemical heating bag according to claim 1 is characterized in that: the ductility of the sealing film 5 is lower than that of other parts. A field mannitol liquid maintenance device based on a chemical heating bag according to claim 1 is characterized in that: one end of the mannitol bag 1 is movably connected to a sealing cap 7 through a threaded tube 6. According to the field mannitol liquid maintenance device based on the chemical heating pack according to claim 1, it is characterized in that the chemical pack 4 contains a mixture of quicklime, iron powder, activated carbon, salt, aluminum powder and coke powder, and the chemical pack 4 allows water to penetrate.

[0031] In the present embodiment, by the layout of well-designed water bag 2, chemical bag 4 and mannitol bag 1, a simple and efficient outdoor mannitol heating system is realized. The system utilizes the heat produced by the chemical reaction of materials such as quicklime in the chemical bag 4 and water, and is conducted to the mannitol bag 1 by the outer bag 3, thereby maintaining the liquid state of mannitol under the outdoor low temperature environment. The design of the sealing film 5 ensures the isolation of the water bag 2 and the chemical bag 4 under the unactivated state, and its low ductility ensures the stability under normal use conditions, and can be easily destroyed by simple physical means such as pressing when needed, realizing the rapid mixing of materials in water and the chemical bag 4. The threaded pipe 6 and the sealing cap 7 design at one end of the mannitol bag 1 not only facilitate the use of mannitol, but also ensure the sealing and reusable possibility of the device. In addition, the use of the soft material makes the whole device light, easy to carry, and variable in shape, which can adapt to different storage and transportation conditions. The permeability design of the chemical bag 4 ensures that water can evenly contact the mixture in the chemical bag 4, thereby achieving uniform heat generation and avoiding the problem of local overheating or insufficient reaction. Overall, the present invention provides a reliable, efficient and user-friendly field mannitol liquid maintenance solution.

[0032] As shown in the figure, a method for using a field mannitol liquid maintenance device based on a chemical heating pack is characterized in that the method comprises the following steps:

[0033] Step A: in the preparation stage, ensure that the mannitol bag 1, the water bag 2, the chemical bag 4 and the outer bag 3 in the device are in good condition, and the sealing film 5 is not damaged;

[0034] Step B: by pressing the water bag 2, the pressure inside the water bag 2 is increased, the sealing film 5 is squeezed, and the water in the water bag 2 flows into the outer bag 3 and contacts the chemical bag 4, and chemically reacts with the mixture of quicklime, iron powder, activated carbon, salt, aluminum powder and coke powder in the chemical bag 4;

[0035] Step C: heat generation: the heat generated by the chemical reaction is transferred to the mannitol bag 1 through the outer bag 3, so that the mannitol remains in liquid state;

[0036] Step D: Use mannitol. When the temperature is suitable, unscrew the cap 7 at one end of the mannitol bag 1 to take out and use the liquid mannitol;

[0037] Step F: Safe storage: After use, re-close the cover 7 to ensure the safety of the device during storage and transportation;

[0038] Step G: Carry and move. Put the device directly into your pocket or backpack to easily carry and move the entire device.

[0039] In the present embodiment, this using method realizes the effective maintenance of mannitol liquid in the field environment by a series of simple and intuitive steps, and ensures the availability of mannitol under low temperature conditions. In step A, the user first needs to conduct a comprehensive inspection to the device to ensure that all components are intact, which is the basis for ensuring the normal operation and safety of the device. In step B, the device is activated by pressing the water bag 2, and this operation is simple and easy, even in an emergency, quick response is also possible. The design of the sealing film 5 enables water to contact the mixture in the chemical bag 4 rapidly, thereby generating necessary heat in step C, and this heat is effectively conducted to the mannitol bag 1 by the outer bag 3, ensuring the liquid state of mannitol.

[0040] In step D, the user can take out the liquid mannitol by unscrewing the cap 7 after confirming that the temperature is appropriate. This design takes into account the convenience and safety of use. Step F emphasizes the handling of the device after use. By reclosing the cap 7, not only the purity and effectiveness of the mannitol are guaranteed, but also the safety of the device during subsequent storage and transportation is ensured. Finally, step G highlights the portability of the device. The user can easily put the device into a pocket or backpack, which makes the device very suitable for carrying and use in the wild or in emergency situations.

[0041] In general, this embodiment provides an innovative method for maintaining mannitol in liquid form in the wild. Through well-designed equipment and simple operating steps, it effectively solves the problem of maintaining mannitol in liquid form in a low-temperature environment, thereby improving the practicality and reliability of mannitol in field medical emergency treatment.

[0042] When in use, firstly, a comprehensive inspection is carried out on the device to ensure that the mannitol bag 1, the water bag 2, the chemical bag 4 and the outer bag 3 are intact and the sealing film 5 is not damaged. Then, the internal pressure of the water bag 2 is increased by pressing the sealing film 5, so that water flows into the outer bag 3 and contacts with the mixture of quicklime, iron powder, activated carbon, salt, aluminum powder and coke powder in the chemical bag 4 to produce a chemical reaction. The heat generated by the chemical reaction is transferred to the mannitol bag 1 through the outer bag 3, so that the mannitol in the mannitol is maintained in a liquid state. When the heat transferred by the outer bag 3 makes the mannitol reach a suitable temperature, the required liquid mannitol is taken out and used by unscrewing the sealing cap 7 at one end of the mannitol bag 1. After use, the sealing cap 7 is reclosed to ensure the sealing of the device for safe storage and transportation. Finally, since the device is small and portable, it can be conveniently put into a pocket or a backpack to achieve easy carrying and movement in a field environment. The entire operation process is simple and fast, and it can be quickly started and used even in an emergency, thereby ensuring the liquid maintenance and effective supply of mannitol in the field or under low temperature conditions.
