Embodiment Construction

[0014] Cooling agent: a composite solution made up of 20% absolute ethanol, 10% glycerol, 20% calcium chloride, 10% sodium chloride, 1% berberine and 39% water by volume. The coolant is made of the principle of lowering the freezing point after compounding chemical substances. It does not freeze at minus 55°C and is in the form of floc. Its heat capacity is 2 cal / g / °C, which can absorb more heat.

[0015] The medicine ice bag with the above-mentioned cooling agent: it includes a soft storage bag for packaging, and the cooling agent is sealed in the soft storage bag. In order to avoid cross-infection, the soft storage bag adopts a medical non-toxic 500ml plastic bag, and 260ml of the above-mentioned coolant is sealed in the plastic bag. The drug ice pack has a plastic shape and is convenient to use, is suitable for different anatomical parts of the human body, can fully contact with skins of different physiological contours, and can cool down rapidly.

[0016] The method of us...

Abstract

The present invention relates to a cooling agent, and medicated ice-bag with said cooling agent and its application method. The cooling agent of said medicated ice-bag is a compound liquor whose composition contains (by volume ratio) 20% of absolute ethyl alcohol, 10% of glycerol, 20% of calcium chloride, 10% of sodium chloride, 1% of berberine and 39% of water. It does not ice at 55 deg.C below zero, and it is made into a flocculent material, its thermal eapacity is 2 calorie/g/deg.C, and it can absorb lots of heat quantity.

Description

technical field [0001] The invention relates to a cooling ice pack, in particular to a drug ice pack suitable for neurosurgery mild hypothermia treatment. Background technique [0002] Physical cooling methods are more and more widely used in clinical medicine, especially in neurosurgery. In the past ten years, theoretical and practical research on the treatment of neurosurgical diseases by hypothermia has been carried out at home and abroad, and certain results have been achieved. At present, the physical cooling products used clinically include ice cubes, chemical ice packs, ice caps, cooling blankets, etc., and have achieved certain results in clinical applications. However, the above-mentioned cooling products also have shortcomings in clinical application: ice cubes melt at 0°C, and the cooling effect is poor; chemical ice packs are prone to chemical burns; although high-tech products such as ice caps and cooling blankets are effective, they are expensive. It is expen...
