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 biuret and 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 to achieve 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 electric energy; 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
The invention belongs to physical therapy articles for use technical field, be specifically related to be used in a kind of medical treatment the quick-freezing ice bag of cold compress.
Background technology
Both at home and abroad on the clinical medicine; For sending out hyperpyretic patient except that the medicament cooling, also must adopt the auxiliary smelting of Physical temperature-lowering means such as ice cube, ice bag, ice cap, hypothermic blanket to treat, make patient's fast cooling; To reduce the oxygen consumption of brain, the protection cerebral tissue does not sustain damage because of hyperpyrexia; In the orthopaedic surgical operations operation,,, often also need local cold compress for alleviating operative site hyperemia, edema often because of operation wound makes contrafluxion swelling.
In the existing shape form formula quick-freezing ice bag, the most simply count water bag, place iced freezing in the refrigerator, take out again when needing.Though this method is easy, to freezing, the overlong time that needs can not satisfy urgent need from water, and solid ice profile and body curve be not inconsistent, and not only cold compress efficient is not high, and uncomfortable.The quick-freezing ice bag that many chemical refrigerations are also arranged on the market; Be " a kind of coolant and have the medicine ice bag of this coolant " like denomination of invention; The principle that patent No. ZL200410023451.3 Chinese patent, coolant adopt the compound back of chemical substance to reduce freezing point is processed, and the ice bag profile is plastic, cooling is rapid; But to place freezing 2.5 hours of the interior cold preservation of refrigerator-freezer before it uses earlier, can not meet an urgent need temporarily.Denomination of invention is " a kind of ice bag ", and publication number is the Chinese patent of CN1308922A, and ammonium nitrate accounts for 98% in its coolant component; Equally, denomination of invention is " no external source refrigeration ice bag ", and publication number is the Chinese patent of CN1442123A; Main component also is a solid ammonium nitrate, and ammonium nitrate is a strong oxidizer, and respiratory tract, eye and skin are had zest; A large amount of contacts of people or oral cause diseases such as methemoglobinemia, when serious even death; Denomination of invention is " medical gelatin ice bag ", the Chinese patent of patent No. ZL200510113968.6, and sodium nitrite has stronger toxicity in the cryogen; Conventional lethal dose 3g; In addition, sodium nitrite still is a kind of carcinogen, eats by mistake human health damage very big accidentally.
Summary of the invention
The purpose of this invention is to provide that to need not refrigerator in advance freezing, can moment refrigeration cool-down, easy to use, cryogen is nontoxic, a kind of quick-freezing ice bag of safety and environmental protection.
For achieving the above object; The technical scheme that adopts is: a kind of quick-freezing ice bag; Comprise refrigeration raw material and sealed water bag that outer packaging bag and said outer packaging bag are built-in with, it is characterized in that the composition of said refrigeration raw material and be: sodium bicarbonate 1～10%, biuret 2～15%, MDU 85～95% in the proportioning of weight percent.
The ratio of the weight of water liquid is 1: 1 in said refrigeration raw material and the sealed water bag.
The refrigeration raw material is graininess in the said outer packaging bag.
Said outer packaging bag is a non-woven bag, and built-in sealed water bag is a plastic bag.
During use outer packaging bag is exerted pressure, as patting extruding or rubbing with hand rubbing, built-in plastic water bag is broken, the water in the sealed water bag is promptly lumped together with graininess refrigeration raw material, and the refrigeration material dissolution reaches the purpose of moment refrigeration cool-down in water and absorb heat as a result.
The invention has the beneficial effects as follows: cryogen is nontoxic, also can be used as organic fertilizer after discarding and is used for fertilising, safety and environmental protection; It is freezing that use first need not refrigerator, not consumed power; Small product size is little, in light weight, and refrigeration speed is fast, ability moment refrigeration cool-down to 7 degree, and static refrigeration is for up to more than 2 hours, and the cold effect time is long, and cooling effect is good; The cooling product is colloidal, and the ice bag shape is plastic, launch conveniently, with need with convenient; Can be used for medical treatment and go up the external application cooling of the various positions of human body, and purposes such as various moment outer package refrigeration, product can also recycle in addition.
The specific embodiment
Embodiment 1:
A kind of quick-freezing ice bag comprises refrigeration raw material and sealed water bag that outer packaging bag and said outer packaging bag are built-in with, it is characterized in that the composition of said refrigeration raw material and in the proportioning of weight percent is: sodium bicarbonate 5%, biuret 10%, MDU 85%.
The weight ratio of water liquid is 1: 1 in said refrigeration raw material and the sealed water bag.The sealed water bag and the refrigeration feed particles that will meet ratio requirement are sealed in the outer packaging bag simultaneously.
Said outer packaging bag is a non-woven bag, and built-in sealed water bag is a plastic bag.
Embodiment 2:
The composition of said refrigeration raw material and change in the proportioning of weight percent: sodium bicarbonate 2%, biuret 3%, MDU 95%, other step is with embodiment 1.
During making, the refrigeration raw material in the outer package can be accordinged to different purposes, and makes the packing of various dose, but the weight ratio of its refrigeration raw material and water bag must be kept 1: 1 ratio, to bring into play best endothermic effect.During use, outer packaging bag is exerted pressure,, built-in sealed water bag is broken as patting extruding or rubbing with hand rubbing; Water in the sealed water bag and graininess refrigeration raw material are lumped together, and the refrigeration raw material progressively dissolves the absorption heat, at normal temperatures; Temperature can plunge to 7 degree, and static refrigeration is for up to more than 2 hours, and the refrigeration raw material progressively changes colloidal into by granular substance; The shape plasticity of ice bag is good, can place brain or other operation wound position of human body, with need with good with convenient clinical effectiveness.Also can put back to refrigerator uses for next recirculation.
