Description

Body surface physics heat sink

Technical Field

The invention relates to a body surface physical cooling device, in particular to medical equipment for reducing the temperature of a human body by smearing a cooling medium on the body surface of the human body, and belongs to the technical field of medical appliances.

Background

The human body fever is caused by the change of the set point due to the fact that a fever activator acts on the body, the generation of endogenous pyrogens is merged into the brain to act on the thermoregulation center, and the release of the medium of the fever center is promoted. Bacterial infection fever, aseptic tissue injury fever and the like can cause the enhancement of tissue metabolism, digestive dysfunction, muscular soreness, headache and even central nervous system dysfunction, and unconsciousness, coma and the like sometimes occur. The commonly used antipyretic methods are divided into physical cooling and taking antipyretic and analgesic medicines, but the medicine cooling has great side effect, and for infants within 2 months, the world health organization recommends that any antipyretic medicine is forbidden. At present, the most common method for physical cooling is to use a cooling patch, but the method has a plurality of defects: firstly, the cooling area is limited, and the cooling paste is only pasted on the forehead part of a human body and has an unobvious cooling effect; secondly, the cooling patch cannot be effectively fixed, and due to a plurality of uncertain factors such as vibration and shaking existing in the daily wearing process, particularly, the infant is more prone to move, the cooling patch is easy to fall off from the human body, and the continuous cooling effect cannot be achieved; and thirdly, the heat dissipation effect is not good, most cooling pastes contain backing materials, the heat of a human body cannot be rapidly dissipated, and the cooling effect is greatly weakened. The existing cooling paste can not be cooled, the real functions are only two, and one function is that a child pastes people around the paste and tells the child to have a fever. Another is that dad mom received a temporary psychological comfort. The efficacy of the existing cooling patch is equivalent to the effect of head application of a cold towel or an ice bag, the general physical cooling of the body is required to cool the whole body, and the forehead of a child is only cooled for a short time without actual effect. In addition, after the existing cooling patch is used for a period of time, the existing cooling patch becomes a hot patch, and the existing cooling patch can not only not be cooled but also can play a role in reaction.

How to correctly apply the physical fever reduction method is a problem of medical commonsense which is urgently needed to be popularized at present. Firstly, there are many ways of physical fever reduction, wherein warm water wiping the body of a child is a relatively simple and effective way, and is suitable for children of all ages, the temperature of water is kept at about 32-34 ℃, the wiping time is kept above 10 minutes, the parts with folds on the body, such as the neck, the armpits, the groin and the like, are mainly wiped, and repeated wiping is preferred when the children have high fever. In addition, the body temperature can be reduced to a certain degree by rubbing and heating the palms and the soles of the children. Some children have fever, the head is very hot, but the hands and feet are very cold, and under the condition, parents need to continuously rub the palms and the soles of the children with hot water, so that the body temperature of the children can be kept balanced, and the children are prevented from rising again. Finally, cold towels are applied to the forehead or the two sides of the nasal wing of the child to reduce the body temperature. The clean towel is soaked in cold water for soaking, is wrung out and then folded and stacked on the forehead and the nasal ala of the child, and is replaced once in 5 minutes. The towel is not twisted too dry, and can be used without dripping water, and the towel is not too cool, and is most suitable for 20-30 degrees.

Therefore, it is very important to develop a physical cooling device that can conveniently wipe the evaporative heat dissipation medium on any part of the body of a child and can adjust the temperature of the evaporative heat dissipation medium.
