Problems solved by technology

However, the existing cold packs are not very convenient to use, and the effect of use is not very good
For example, the "pull bag type chemical ice bag" disclosed in the CN2054158U patent, the patented water bag is sealed with pressure-sensitive adhesive, which is prone to double water seepage, which affects the product quality and is inconvenient to store
CN2254737Y patent discloses "portable disposable ice bag", its inner bag is relatively strong, but it is not easy to be pinched and broken, and it is inconvenient to use. At the same time, the inner bag is easily damaged during transportation, which is not convenient for transportation
The "ready-to-use cold compress bag" disclosed by CN2542230Y patent is inconvenient when the inner bag is torn, which affects the use
At the same time, the refrigeration time of ordinary chemical cold compress bags is short, and the refrigeration effect is not good.

Embodiment 1

[0023] Weigh 120g of urea, 28g of ammonium chloride, 28g of potassium nitrate, 9g of guar gum, and 115g of water, and put them into the outer bag 1. Seoul glue), in which four kinds of solid materials 3 and water 4 are respectively placed on both sides of the outer bag, sealed and separated by a sealing strip 2 in the middle, and the outer bag is divided into a solid bag 11 and a water bag 12, and the sealing strip 2 is fixed in the bag , when the cold pack needs to be used, the sealing strip 2 only needs to be pulled away, and the water 4 in the water bag 12 can be mixed with the solid material 3 in the solid bag 11 to play the role of refrigeration.

[0024] The effect of using the cold compress bag (performance test):

[0025] Under the condition of ambient temperature of 25°C, the minimum temperature of the cold compress bag is 3°C, and rises to room temperature after 2.5 hours.

[0026]

Embodiment 2

[0028] Weigh 100g of urea, 35g of ammonium chloride, 35g of potassium nitrate, 15g of guar gum, and 115g of water, and put them into outer bag 1. Seoul glue), in which four kinds of solid materials 3 and water 4 are respectively placed on both sides of the outer bag, sealed and separated by a sealing strip 2 in the middle, and the outer bag is divided into a solid bag 11 and a water bag 12, and the sealing strip 2 is fixed in the bag , when needing to use cold compress bag, only need to pull sealing strip 2, the water in the water bag 12 just can be mixed with the solid material in the solid bag 11, plays the effect of refrigeration.

[0029] The effect of using the cold compress bag (performance test):

[0030] At an ambient temperature of 25°C, the minimum temperature of the cold pack was 2°C, and it rose to room temperature after 3.0 hours.

[0031]

Embodiment 3

[0033] Weigh 110g of urea, 28g of ammonium chloride, 28g of potassium nitrate, 14g of guar gum, and 120g of water, and put them into the outer bag 1. Seoul glue), wherein the four solid materials and water are respectively placed on both sides of the outer bag, and the middle is sealed and separated by a sealing strip 2, and the outer bag is divided into a solid bag 11 and a water bag 12, and the sealing strip 2 is fixed in the bag. When the cold compress bag needs to be used, the sealing strip 2 only needs to be pulled away, and the water in the water bag 12 can be mixed with the solid material in the solid bag 11 to play the role of refrigeration.

[0034] The effect of using the cold compress bag (performance test):

[0035] At an ambient temperature of 25°C, the minimum temperature of the cold pack is 0°C, and it rises to room temperature after 2.5 hours.

Abstract

The invention discloses a cold-accumulation type refrigerant and a cold-accumulation type cold compress bag. The refrigerant comprises the following components in percentage by weight: 30-40% of urea, 6-12% of ammonium chloride, 6-12% of potassium nitrate, 2-5% of guar and 35-45% of water. The cold compress bag comprises an outer bag, wherein solid materials comprising the refrigerant and water are arranged in the outer bag, and a sealing strip is arranged in the outer bag to separate the solid materials from the water. The refrigerant disclosed by the invention comprises three refrigerants, the solution heat of the cold compress bag is increased by various refrigerants, and the cold compress effect is better. Because the macromolecule edible-grade guar gum is added in refrigerant particles, the cold compress time of the cold-accumulation type cold compress bag disclosed by the invention is 2-3 times longer than the traditional common cold-accumulation type cold compress bag, so that the whole system is in a colloid shape and is unlikely to flow, and the use comfort level of a patient is improved. The solid materials and the water are separated by the sealing strip, and the cold compress bag is convenient to use; and in the transportation process, the solid materials and the water can be effectively separated and cannot be mixed, which is convenient for transporting the cold compress bag.

Description

technical field [0001] The invention relates to a refrigerant and a cold compress bag, which are mainly used for human body fever, trauma physical cooling and summer travel cooling, and are used in the medical field and family health care. Background technique [0002] Cold packs are the first choice for physical cooling and cold compress physiotherapy, which are widely used in medical and health institutions. In addition to their direct cooling effect, cold packs can also shrink local capillaries, reduce local bleeding, reduce edema and congestion, and inhibit sensation. Nerves, relieve pain, relieve symptoms. [0003] Cooling measures in hospitals today include ice cubes, cold packs, ice blankets and ice caps, and ice packs. Ice cubes are the most traditional cooling method. A long time ago, people put towels soaked in ice water or wrapped in ice cubes on the patient's forehead to cool down, and this cooling method has been continued, but ice cubes The hardness is too hi...
