Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a bathtub which can be transformed into a backpack for emergency treatment of heat stroke. Background Art

[0002] Heatstroke is the most severe form of heatstroke, characterized by a sharp rise in core body temperature above 40°C, accompanied by neurological dysfunction (including delirium, convulsions, and coma), coagulopathy, and multiple organ failure, resulting in a high mortality rate. Prehospital management of heatstroke involves identification, cooling, and transport. First-aiders and medical personnel at the scene are required to rapidly identify heatstroke patients, decisively implement cold water immersion (CWI) cooling, and flexibly apply all cooling methods to achieve effective cooling. Fluid rehydration, sedation, and oxygen therapy are administered while continuously monitoring vital signs. Once cooling targets are achieved, standardized transport is performed. Prehospital management of heatstroke should adhere to on-site protocols of rapid identification, effective cooling, and standardized transport to maximize the success rate of heatstroke treatment. Early and rapid cooling is the key to primary treatment, while standardized transport to a qualified hospital is the prerequisite for subsequent treatment.

[0003] The goal of early rapid cooling is to reduce core body temperature (generally based on rectal temperature) to below 39°C within 0.5 hours (from onset). Literature documents various common early rapid cooling measures for heat stroke emergency treatment. Currently, the most effective method for lowering core body temperature in heat stroke patients is cold water immersion, which is recognized as the "gold standard" for cooling. Cold water immersion involves immersing the patient's entire body in a bathtub filled with cold water. However, this cooling method is not easy to implement, especially in specific circumstances, such as workers working outdoors or troops conducting field training or combat. Existing bathtubs are large and inconvenient to carry, so outdoor workers or medical personnel accompanying combat operations rarely carry bathtubs. Consequently, even when there is a water source outdoors, there is no suitable bathtub to use, which can delay early treatment for heat stroke patients. Utility Model Content

[0004] The purpose of the utility model is to provide a bathtub that can be transformed into a collection backpack for heatstroke first aid. The utility model has the advantages that it can be transformed into a bathtub when in use for heatstroke patients to soak in water and cool down; after use, it can be transformed into a backpack with a small size and is easy to carry.
