Ice cubes are the most traditional way to cool down. A long time ago, people used towels soaked in ice water or wrapped in ice cubes to cool the patient's forehead, and this way of cooling has been continued, but ice cubes The hardness is too high, it is not easy to shape, and the temperature is too low, all below zero, which often causes secondary trauma to unconscious patients-frostbite, so the discomfort caused by ice cooling is obvious, especially In hospitals with insufficient manpower, this has prompted people to find other more effective and more comfortable ways to cool down, so cold packs have appeared.
There are mainly two kinds of cold compress bags on the market. The first one is mainly disposable. After the reaction, it is in a liquid state, easy to flow, not convenient to fix, and the cooling time is relatively short. Generally, it can only last for more than ten minutes. In use, this kind of cold pack is basically similar to an ice pack, with short refrigeration time and large consumption, which provides limited convenience for medical staff;
The other is a new product, which combines instant cold and cold storage. First put the technological ice in the water and knead it with your hands to expand the technological ice. It is the best state to expand to about 1 cm. After the expansion is complete, take it out and take it out. The moisture on the surface is wiped dry, and then it can be used in the refrigerator. In addition, the first generation cold compress bag has been improved to change the shortcomings of one-time use. Therefore, the full cold compress bag can be used repeatedly, and the cooling time It has also been extended from ten minutes to two hours. It is in a gel state under refrigeration, not easy to flow, has a wide contact surface with the skin, and has a high degree of comfort. It replaces the traditional ice pack, the temperature is suitable, and the traditional ice cube warm clothing is too low. The hardness is too large, which is easy to cause discomfort to the patient. It solves the problem of not easy to move and high overall cost. In addition, it is convenient to transport, and the outer bag has strong compressive capacity. It can withstand a weight of 30 kg without being damaged. There is no need to worry about the outer bag. broken.
