Description

Cold accumulation type active refrigeration high-efficiency cooling paste

Technical Field

The utility model belongs to the technical field of the subsides of bringing down a fever, specifically speaking relates to a high-efficient subsides of bringing down a fever of cold-storage type initiative refrigeration.

Background

The antipyretic patch has the effects of antipyresis and cooling, can relieve fever, headache, toothache, solarization, muscle sprain and other symptoms of pain, and is generally a gel patch, wherein hydrogel plays a vital role in the antipyretic effect of the antipyretic patch, and the principle is that water is evaporated to take away heat, thereby realizing the antipyretic effect.

Because the weight of the cooling paste is light, the contained hydrogel is limited, and the temperature reducing effect of the cooling paste is very limited in the using process and the continuous low-temperature effect can not be maintained for a long time; in addition, cool components such as menthol, borneol and the like are added into the antipyretic patch, which only has psychological hint effect on people and has little effect on physical cooling. Therefore, a new cooling patch is needed to solve the problems of poor physical cooling effect and short duration of the existing cooling patch.

Disclosure of Invention

To the above-mentioned problem that prior art exists, the utility model aims to provide a high-efficient subsides of bringing down a fever of cold-storage type initiative refrigeration adopts the cold-storage agent to reach the refrigerated purpose of initiative, make the functional reinforcing of product, duration extension.

In order to solve the above problems, the utility model adopts the following technical proposal.

The utility model provides a high-efficient subsides of bringing down a fever of cold-storage type initiative refrigeration, includes hydrogel layer, hydrogel layer is equipped with the coolant layer outward, be equipped with airtight isolation layer between hydrogel layer and the coolant layer, airtight isolation layer can be opened or remove wantonly.

After the sealed isolation layer is opened, in order to prevent hydrogel layer and coolant direct contact, the coolant refrigeration influences the effect of bringing down a fever and the time of bringing down a fever too fast, still be equipped with ventilative isolation layer between hydrogel layer and the airtight isolation layer.

Selecting a water-absorbing and cold-releasing efficient cold storage material, wherein the cold storage agent of the cold storage agent layer is urea, ammonium nitrate, calcium ammonium nitrate or ammonium chloride.

For convenient to use, airtight isolation layer is the barrier film who takes the blasting line, and when not using, the hydrogel layer is kept apart with the coolant layer completely, prolongs the shelf life of product, during the use, pulls open airtight isolation layer and makes the blasting line fracture, can make the coolant granule absorb the steam that hydrogel layer distributed out and refrigerate.

The cold accumulation agent layer is coated with self-adhesive and used for enabling cold accumulation agent particles to be uniformly distributed.

From the side close to the skin, the isolating film, the hydrogel layer, the non-woven fabric layer, the closed isolating layer with the blasting line and the coolant layer are respectively arranged from inside to outside.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a structure that cold-storage agent and aquogel combine reaches the refrigerated purpose of initiative, makes the functional reinforcing of product, and the duration extension, the subsides of bringing down a fever after the improvement reduce 3 ~ 5 ℃ than the ordinary subsides of bringing down a fever temperature that only adopt aquogel, and the length of bringing down a fever promotes to 3 ~ 5 times, has simple structure, reasonable in design, easily manufactured advantage.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Example 1

The cooling paste as shown in fig. 1 is composed of a first isolation layer 1, a hydrogel layer 2, a second isolation layer 3, a third isolation layer 4 and a coolant layer 5 from inside to outside from one side close to the skin, wherein the first isolation layer 1 is an isolation film and is torn off during use, the hydrogel layer 2 is adhered to the skin, the second isolation layer 3 is an elastic non-woven fabric layer (namely, a breathable isolation layer), the third isolation layer 4 is an isolation film with a blasting line (namely, a closed isolation layer), and the central area of the third isolation layer 4 is a blasting line 7 as shown in fig. 2.

The cold-storage agent is selected from urea, the cold-storage agent layer 5 and the periphery of the third isolation layer 4 are sealed together in a heat sealing mode, and then the cold-storage agent layer and the second isolation layer 3 are sealed in a heat sealing mode. When the improved cooling patch is used, the middle part of the cooling patch is pressed, the two ends of the cooling patch are pulled reversely, the hydrogel layer and the non-woven fabric layer are made of telescopic materials, the third isolation layer 4 can crack at a blasting line, the cold storage agent absorbs water vapor emitted by hydrogel, a refrigerating effect is generated, and therefore the purposes of actively refrigerating and assisting in reducing the temperature of the cooling patch are achieved, the temperature of the improved cooling patch is reduced by 3-5 ℃ compared with that of a common cooling patch only adopting hydrogel, the cooling duration is prolonged to 3-5 times, and the effect is remarkable.

Example 2

The cooling patch of this embodiment is substantially the same as embodiment 1, except that the coolant is ammonium nitrate, the coolant layer 5 is provided with a non-drying adhesive layer, the particles of the coolant 6 are uniformly adhered thereon, so that the cooling is uniformly released, and the product is light and flat.

The present invention has been described in terms of the above embodiments, it should be understood that the above embodiments are not limited in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation modes fall within the protection scope of the present invention.
