Abstract
A kind of safety cool bag (or ice bag) is to be refrigeration host with urea (accounting for 70～90%), adds a spot of ammonium nitrate (accounting for 10～30%) and is made as refrigerant for the salt-mixture of auxiliary agent.This cold bag is preserved safety, the nontoxic environmentally safe of refrigerant.As long as sealed water bag in the cold bag is squeezed broken, treat that water flows out to contact with refrigerant can produce cooling effect cold bag of minimum reaching-5 ℃ during use.Can be widely used as medical treatment, particularly use as provisional refrigeration source during outdoor sports.In addition, this cold bag cost is low, can use repeatedly and also can be used as the disposable product use.
Description
The invention belongs to family or medical supplies, specifically provide the cold bag that uses in a kind of life and the medical procedure.
Usually need to carry out part cooling in life and medical procedure, particularly during the refrigeration of activity temporary needs in the open air, provide a kind of convenient refrigeration articles for use or method outstanding apparent important.It is found that some salt, can absorb a large amount of heats when particularly ammonium salt is water-soluble and cause self temperature reduction, this characteristic based on salt, it can be packed in the container, when salt is water-soluble in this container, the temperature of container can descend rapidly, and this container promptly can be used for as a kind of refrigeration source easily or is referred to as cold bag (or ice bag).The existing report of cold bag that adopts this method to make at present, for example cold bag of making for refrigeration host of ammonium nitrate.But because the ammonium nitrate instability, safety is inadequately preserved and used to therefore this cold bag.The price of ammonium nitrate is higher simultaneously, and the cost of making the cold bag of refrigerant making with it is also higher.
The invention provides a kind of safe cold bag, it not only has better cooling effect, can be widely used in life and medical procedure the refrigeration source is provided, and the refrigerant of its use is nontoxic simultaneously, and environmentally safe uses the back easily to handle.In addition, this refrigerant price is low thereby reduce its production cost.
It is refrigeration host that cold bag of the present invention is selected urea for use, be mixed with a small amount of ammonium nitrate and put into a closed container for adding auxiliary agent, for example: can be placed in the nylon plastic(s) bag, put into the water bag of a sealing simultaneously, when water bag is squeezed when broken, urea and ammonium nitrate is soluble in water to be absorbed a large amount of heats simultaneously and make container is consistent low-temperature receiver, is cold bag.When the weight of urea refrigeration host is 70～90%, the weight of ammonium nitrate is 10～30%, and its cooling effect of mixing freezing salt of preparation is better.When room temperature was 27 ℃, refrigeration cold bag of moment can reach-5 ℃, and going back up to room temperature approximately needs half an hour, therefore can be used as a kind of more convenient refrigeration source and uses.Below by example cold bag of the present invention is described further.
Example 1, safety cool bag
Put refrigerant 200 grams (urea 160 grams, ammonium nitrate 40 grams) that mix with the nylon plastic(s) bag, and put into the sealed plastic bag of containing into 250 gram left and right sides water, then the nylon plastic(s) bag is sealed (hot pressing), make cold bag.
During use in the extruding nylon plastic(s) bag water bag it is broken, the nylon plastic(s) bag begins cooling when meeting salt-mixture when water flows out, refrigeration approximately can keep about 30 minutes.This cold bag can be put into refrigerator after once using, and can use repeatedly after freezing again.After once using as the cold bag of outdoor sports, the nylon plastic(s) bag can be cut and bleed off solvent.Because refrigerant selects for use urea and ammonium nitrate that environment is not had any pollution.Do refrigeration source and sports in summer when this cold bag can be widely used in medical treatment, do provisional refrigeration source in field work or the tourism.It is very easy to use, preserves safety, and simultaneously cold bag cost is very low, is suitable for doing disposable refrigeration product and uses.
