Can ice packs be reused over and over again, and will their use have an effect on the body? This question is particularly good, good enough to be grounded, and very much in line with our ordinary people's lives. In addition, it is also in line with today's pursuit of safe, hygienic life concept. As a matter of fact, most of the ice packs on the market today, its main ingredient is ice. Moreover, from a scientific point of view, ice packs are generally categorized into reusable ice packs and disposable ice packs. Reusable ice packs can be used repeatedly, and disposable ice packs can also be used many times in the case of careful and prudent use, try not to use it many times. Ice packs are a novel freezing medium, its thawing and melting without water contamination, can be used repeatedly, hot and cold use, its effective use of cold capacity for the same volume of ice 6 times, can replace dry ice, ice, etc.. When you use it, you should look at the shelf life, use it within the shelf life, if there is no shelf life with a year on it. When you don't use it, just put it in a clean bag and put it in the freshness area.
So, ice packs can generally be used repeatedly, there is no harm. Of course, I say this with a premise, that is, the outer surface of the ice pack is not contaminated. But the fact is that ice packs are generally used for patients, so it is inevitable that they will come into contact with all kinds of bacteria. And such an ice bag, obviously can not be reused many times oh. For example, the following two scenes, will use ice packs, but can not be reused.
Scene one: the use of ice packs to children cooling. If the fever is too long or the body temperature is too high, the consumption of nutrients or oxygen in the body will increase, affecting the normal metabolism, there will be a series of uncomfortable symptoms, high fever will also affect the brain function. Therefore, children's fever should first take physical cooling, the ice pack from the refrigerator, wrapped in a towel on the head can quickly lower the temperature, to protect the brain. However, please note that this time after the use of the ice bag, I am afraid that has been contaminated with cold virus, so it is not recommended to use the second time.
Scenario 2: Using ice packs to relieve pain from sprains. Sprains are caused by a sudden and violent twisting of the joint, twisting the ligaments and tendons outside the joint. Usually, the ankle joint sprains more in sports, the first step is to immediately stop the movement, followed by ice. In the early stages of a sprain, the ruptured blood vessels are bleeding, and icing will allow the blood vessels to constrict and clot, controlling the progression of the injury. Please note that the ice pack in this scenario, it is also best not to reuse, for the same reason as scenario one.
