Principle of antipyretic patch

Whether adults or children have a fever, it is important to reduce the fever in time, because fever is a symptom of disease caused by damage to the human brain nerves. If the fever is not treated in time, it will seriously damage the human brain nerves and even cause intellectual problems. In addition to using some physical methods or antipyretic and anti-inflammatory drugs to reduce fever, fever-reducing patches have also become a method used by many people. What is the principle of the fever-reducing patch?

How the fever-reducing patch works

The fever-reducing patch is a physical way to reduce temperature.

The fever-reducing patch achieves the effect of rapid cooling through the physical change of water vaporization and heat absorption. It has the characteristics of emergency response to high fever, safe fever reduction, rapid temperature reduction, and brain protection. It is a commonly used physical cooling product, so it is widely used in children's colds and fevers. Representative products include Parachute Antipyretic Patch, Ice Nurse Antipyretic Patch, etc.

The fever-reducing patch is made of gel. During use, the moisture in the gel vaporizes, thereby evaporating the heat in the body. It has a physical heat dissipation effect on fever caused by colds, infections, etc., while not destroying the immune system response in children. The cooling time of the fever-reducing patch is generally more than 6 hours. It is a physical cooling product, safe and non-toxic.

Composition of antipyretic patch

The basic structure of the antipyretic patch consists of an anti-sticking layer, a drug reservoir gel layer, a backing layer and other parts.

Anti-sticking layer: a transparent protective layer of PC isolation paper, a layer of polyester protective film attached to the surface of the patch, a medical embossed plastic film, which is peeled off before use and is used for anti-sticking and moisturizing.

Medicine reservoir gel layer: It is the main part, with hydrophilic polymer gel with good energy conversion function as the carrier, and a variety of natural cool and aromatic plant extracts are added into it, which has the dual effects of physical cooling and Chinese medicine conditioning and care. While quickly reducing the temperature physically, it effectively relieves fever symptoms and protects the brain, killing two birds with one stone.

Backing layer: Made of pharmaceutical grade non-woven fabric, breathable and waterproof, which increases the breathability and anti-shedding properties of the product.

Can the fever-reducing patch be reused?

First of all, repeated use is not recommended.

In order to maintain hygiene and freezing effect, please use each antipyretic patch once and do not use it repeatedly, which will greatly reduce the cooling effect. Generally, a fever-reducing patch will become thinner after 8-10 hours of use. At this time, it can be discarded. Do not put it in the refrigerator for reuse. You should replace it with a new one.

After applying the antipyretic patch, the heat on the skin will be absorbed by the polymer gel layer and dissipated through vaporization, thereby achieving the purpose of continuously taking away the body's heat. The cooling time of the antipyretic patch is generally about 6 hours. If the child is still running a fever, you can replace it with a new one.

A piece of antipyretic patch can generally work for 6-8 hours, and the longest time it can be used is about 10 hours. Because the baby's skin is delicate, it may cause redness or skin allergies if it is used for a long time. Therefore, when the baby's body temperature is below 38 degrees, you can remove it.

Antipyretic patches only dissipate heat but do not cure diseases. Their fever-reducing effect is only temporary. Their fever-reducing effect is limited and the fever may come back again after a while. Therefore, they are only suitable for auxiliary treatment of low fever or taking antipyretic drugs at the same time. Although the fever-reducing patch cannot completely reduce the fever, it can relieve the headache and discomfort caused by fever and make the baby more comfortable, which is also valuable.

Note:

Although many parents hope that their baby can cure fever by using fever-reducing patches, in fact, the main function of fever-reducing patches is to lower the local temperature of the brain, slow down the brain's metabolism, and thus protect brain cells. Parents should not think that it is safe to put a fever-reducing patch on their children. If the body temperature exceeds 38.5℃, they need to take antipyretics!
