Ice cubes are the most traditional way to cool down. A long time ago, people used iced water or iced towels to cool the patient's forehead, and this cooling method has been continued, but ice cubes. The hardness is too large, not easy to mold, and the temperature is too low, all below zero, often causing secondary trauma to the unconscious patient - frostbite, so the discomfort caused by ice cooling is obvious, especially In hospitals where there is not enough staff, this has prompted people to look for other ways to cool down more effectively and comfortably, so there is a cold pack.
There are two main types of cold packs on the market. The first one is mainly disposable. After the reaction, it is in a liquid state, easy to flow, inconvenient to fix, and the cooling time is relatively short. Generally, it can only last for ten minutes. Used again, this cold pack is basically similar to an ice pack, has a short cooling time and a large consumption, and has limited convenience for medical personnel;
The other is a new product, which is a combination of cold and cold storage. First put the technology ice in the water, hand rub it, make the technology ice expand, expand to about 1 cm is the best state, expand it and take it out. The surface moisture is dried and then frozen in the refrigerator. It is also improved on the first generation of cold packs, which changes the shortcomings of single use. Therefore, the full cold pack can be used repeatedly, and the cooling time It is also extended from ten minutes to two hours. It is in a gel state during cooling. It is not easy to flow. It has a wide contact with the skin and high comfort. It replaces the traditional ice, and the temperature is suitable. The traditional ice block is too low. The hardness is too large, which is easy to cause discomfort to the patient. It solves the problem of difficulty in moving and high comprehensive cost. In addition, it is convenient to transport, and the outer bag has strong pressure resistance. It can withstand 30 kg of weight without damage, and there is no need to worry about the outer bag broken.
