Background

With the improvement of the life quality of people, except for production and labor, outdoor activities and physical exercises become normal, and the occurrence of accidents such as sprain, strain, muscle and bone injury and the like is also improved inevitably. When the events happen, the method for assisting in relieving pain and stopping bleeding and cooling by adopting a physical cooling means becomes an indispensable method, and the most common small medical apparatus is a medical ice bag. Besides being easy to use under the conditions of outdoor labor, physical exercise and the like, the medical ice bag can also be used for relieving daily cold, fever, burn, scald and the like. The medical ice bag is particularly commonly used in foreign medical clinic and surgical operations, and the use of the medical ice bag and instruments such as ice blocks, ice caps, cooling pads and the like is generally called as cold therapy.

The ice bags on the market are of a self-filling type and a quick-cooling type. Some self-filling ice bags need cold sources and some need water sources, and when accidents happen temporarily, the use of the ice bags is limited, if the ice bags cannot be cooled quickly, the human body can be damaged, and the risk that the treatment cannot be carried out in time exists, so that the quick-cooling ice bags are more popular in daily storage of people. The quick-cooling ice bag has various types: the cold source is needed, the self-filling type, the anhydrous type and the combination of the traditional Chinese medicine and the water-free type are needed. Although there are many kinds, there are also limitations: the quick-cooling ice bag which needs a cold source and is self-filling limits the use environment, the anhydrous quick-cooling ice bag has poor refrigeration effect sometimes, and the quick-cooling ice bag combined with the traditional Chinese medicine has a complex structure and is selective to applicable wound surfaces, so the quick-cooling medical ice bag which is wide in application range, free of the cold source, simple in structure and convenient to carry is urgent for people.

CN203291107U discloses a self-filling quick-cooling ice bag. Quick-cooling ice bag is utility model relates to a from quick-cooling ice bag of notes, include: anti-sticking coating, flowing backward line, ice bag body and endothermic reaction chemicals, its characterized in that: a sealing line and an easy-to-tear opening are newly arranged above the position of the bag opening where the anti-sticking coating is located, wherein the easy-to-tear opening is located below the anti-sticking coating, the backflow line is located below the anti-sticking coating and extends into the bag opening, and the lower part of the ice bag body contains endothermic reaction chemicals. This utility model is on the basis of prior art, to the careful improvement of ice bag leakproofness to make it more humanized.
