Quick-freezing ice bag

Abstract

The invention relates to a quick-freezing ice bag, which comprises a packaging bag, wherein the packaging bag is internally provided with a refrigerating raw material and a sealed water bag. The quick-freezing ice bag is characterized in that: the refrigerating raw material comprises the following components in percentage by weight: 1 to 10 percent of sodium bicarbonate, 2 to 15 percent of biuretand 85 to 95 percent of methylene diurea. The weight ratio of the refrigerating raw material to water in the sealed water bag is 1:1. When the quick-freezing ice bag is in use, the packaging bag is pressed by beating, squeezing or rubbing with hands so that the plastic water bag in the packaging bag is broken and the refrigerating raw material is dissolved into the water and absorbs heat so as toachieve the purposes of instant refrigerating and cooling. The quick-freezing ice bag has the advantages that: a refrigerant is non-toxic and harmless, can also be used as an organic fertilizer for fertilization after being abandoned, and is safe and environment-friendly; the quick-freezing ice bag is unnecessary to be frozen by a refrigerator when used for the first time and consumes no electricenergy; the quick-freezing ice bag has a small volume, a light weight, a quick refrigerating speed, instant refrigerating and cooling, long cold effect time and a good refrigerating effect; and a cooled product is colloidal, the shape of the ice bag is mouldable, and the ice bag is convenient and fast to open and use as required.

Description

technical field [0001] The invention belongs to the technical field of physiotherapy supplies, and in particular relates to a quick-cooling ice pack used for cold compress in medical treatment. Background technique [0002] In clinical medicine at home and abroad, in addition to using drugs to cool down the temperature of patients with high fever, ice cubes, ice packs, ice caps, cooling blankets and other physical cooling methods must be used to assist in the treatment, so that the patient can quickly cool down and reduce the oxygen consumption of the brain. Protect brain tissue from damage due to high fever; in surgical operations, local congestion and swelling are often caused by surgical trauma. In order to reduce congestion and edema at the surgical site, local cold compresses are often required. [0003] Among the existing forms of quick-cooling ice packs, the simplest water pack is placed in the refrigerator to freeze and freeze, and then taken out when needed. Althou...

Problems solved by technology

Although this method is simple, it takes too long from water to freezing, which cannot meet urgent needs, and the shape of solid ice does not conform to the curve of the human body. Not only is the cooling efficiency not high, but it is also uncomfortable.

There are also many chemical refrigeration quick-cooling ice packs on the market, such as the invention titled "a coolant and a drug ice pack with the coolant", patent No. ZL200410023451.3 Chinese patent, the coolant is compounded with chemical substances to lower the freezing point The principle is made, the shape of the ice bag is plastic, and the temperature can be cooled quickly, but it must be refrigerated and frozen in the freezer for 2.5 hours before use, and it cannot be used for emergency

The title of the invention is "a kind of ice bag", the publication number is the Chinese patent of CN1308922A, and the ammonium nitrate accounts for 98% in the coolant component. The main component is also solid ammonium nitrate, and ammonium nitrate is a strong oxidant, which is irritating to the respiratory tract, eyes and skin. People who contact it or take it in large quantities can cause diseases such as methemoglobinemia, and even death in severe cases; the invention name is "medical gelatin ice pack ", the Chinese patent with the patent number ZL200510113968.6, sodium nitrite in the refrigerant has strong toxicity, and the conventional lethal dose is 3g. In addition, sodium nitrite is also a carcinogen, and ingestion is extremely harmful to human health.
