The medical cooling bag is widely used to treat sprains, bruises and other conditions when it is necessary to reduce the temperature of the affected area. This helps to reduce inflammation and prevents further progression of the disease state.
Areas of use
With an insect bite or joint inflammation, the medical cooling pack is an indispensable tool, especially when you are on the road or away from places where you could be given first aid. This versatile and simple medical device allows you to quickly stop heat stroke, thereby preventing the development of complications in the cardiovascular system, which in such cases develop very rapidly. Timely provided cold therapy avoids or at least reduces the likelihood of edema and hematomas that cause pain and impaired blood supply to the tissues.
An important area of application for cold packs is the transport of drugs. For example, medicines such as vaccines, if temperature storage conditions are not observed, can go bad in just a few hours. In this case, medical cold is the only reliable way to deliver such drugs to their destination.
Composition
The medical cooling bag is a sealed plastic form containing components inside that, when mixed, enter into a chemical reaction between themselves, as a result of which cold is released. When water interacts with ammonium nitrate, an endothermic process is launched, the essence of which is the rapid absorption of heat from the environment.
The cooling medical package in the course of the reaction taking place inside it lowers its temperature to values in the range from 0 ° C to +5 ° C. Moreover, it retains its cooling properties for up to 40 minutes, and this time is just enough to provide first aid and prevent the development of complications.
The reusable cooling medical bag, unlike the single-use bags, contains a special gel inside that can accumulate both heat and cold inside. In order for the shell of such a package to retain its physical properties, it is made from high-strength material developed using innovative technologies. The composition of the medical cooling bag is non-toxic and remains safe for humans, both when cooling and when heated.
Mode of application
The preparation of a gel reusable bag for use consists in putting it in the freezer for about 30 minutes. If there is no freezer nearby, ordinary cool water can be used as a cooling medium. When the gel pack has cooled sufficiently, it can be applied to the affected areas of the body. In order for the product to have the necessary therapeutic effect and not lead to damage to tissues and blood vessels, a compress is applied for no more than 20 minutes. It is important to note that at least 20 minutes must also pass before reusing the medical package.
For quick activation of a single-acting hypothermic packet , it must be actively kneaded to release the water necessary for the reaction, which is in a very fragile plastic bag. Moreover, the more ammonium nitrite simultaneously reacts, the faster the decrease in temperature of the cold pack will occur. Rapid cooling can be achieved with the complete release of the water inside, which interacts with the reagent. This is a very effective and improvised way to stop bleeding.
Characteristics
Hypothermic cooling package is not allowed to be stored under direct sunlight, and should not be kept near open sources of heat. These medical products come in different weights and sizes.
Modern manufacturers do not stop at the simple forms of these indispensable packages and produce them in the form of special bandages that are easily attached to any part of the body.
