Description

The small-sized Portable safety cold compress patch of reaction rate controllable type based on Nano capsule

Technical field

The utility model is a kind of chemical reaction rate controllable type microminiature portable safety cold compress patch based on Nano capsule, Also referred to as " scalding can paste ", can handle the slight scald problem that human skin in daily life encounters.

Background technique

In daily life, our human skins may be due to by some slight accidental scaldings, needing using cold Deposited mode is alleviated.In addition, cold compress can also play the function of shrinking local vascular, eliminate swelling pain, it can be urgent It copes with some acute injuries, local inflammation, sprain the problems such as pain.

Cold compress will generally carry out as early as possible to have effect after injury, and in some outdoor occasions, generally have little time to prepare As towel, ice cube article carry out cold compress, it is therefore necessary to provide a kind of cold compress device being convenient for carrying, can at any time with Cope with emergency in ground.

As long as device has heat-absorbing action, so that it may play the effect of cooling, such as common ice cube cold compress is exactly to utilize The principle of ice-out heat absorption；Using inorganic salts as cold compress medium be then be dissolved in using it water heat absorption principle.But either ice Block, which melts, or inorganic salts are dissolved in water all can make the water that savings is more in device, be unfavorable for the miniaturization of device, also just can not be square Portable belt.In addition to the above physical process, also the effect of cooling can be can achieve with endothermic process in chemical reaction, but During chemical reaction, the volume of reactant and product be should not be too large, and be required to provide enough caloric receptivities.Pass through choosing It selects reasonable reactant to be chemically reacted, so that it may accomplish the miniaturization of cold compress device.

Summary of the invention

For miniaturization, the portability for realizing cold transmitting apparatus, the utility model uses following design scheme: with NH₄Cl solid Powder and Ba (OH)₂·8H₂For O crystal powder as reactant, reactional equation is as follows:

Ba(OH)₂(s)+2NH₄Cl (s)=BaCl₂(s)+2NH₃(g)+2H₂O(l)

Product BaCl after reaction₂For solid, while a small amount of water and ammonia are generated, ammonia is water-soluble, so cold compress The volume of patch can diminution as far as possible to achieve the purpose that miniaturization.This reaction has stronger endothermic effect, while Ba (OH)₂For crystalline hydrate, needs to absorb heat from solid variation liquid and complete phase transition process, further increase caloric receptivity.

Meanwhile to reach the endothermic effect that device is maintained for a long time, portion contains with reaction reagent mixing portion in the device There is the Nano capsule of solid-liquid phase change material.Such Nano capsule react carry out when self heat absorbed by reactant, temperature with Reaction is declined, until solid-liquid phase change material when a certain temperature inside Nano capsule solidifies.As reaction carries out, reaction rate When reduction, device bulk temperature is gone up, and outside heat is absorbed in Nano capsule, slows down the rate of temperature rising, and it is anti-to reach control Answer rate, persistently to the purpose absorbed heat at injury.

Based on the above reaction principle, minimized as far as possible to make to design cold compress device, and can sustained response it is enough when Between, meet the duration requirement of cold compress, the utility model is achieved through the following technical solutions:

The utility model is a kind of small-sized Portable safety cold compress patch of the reaction rate controllable type based on Nano capsule, packet It includes: insulation face, heat-absorbent surface, small structure barrier material, fixing belt, the chemical reaction reagent of two kinds of endothermic reactions and comprising solid Liquid phase-change material, which is used to absorb heat, stores the Nano capsule of cooling capacity.

Nano capsule structure refers to using solid particle, liquid droplet or gas as the core material of capsule, is formed outside it The structure of one layer of continuous and very thin cyst wall.The substance that Nano capsule used by the utility model includes inside it is under room temperature Mixing solid-liquid phase change material in liquid, condensation point are 6.2 DEG C, mass ratio is 2:3 laruyl alcohol and octanoic acid.The utility model institute The Nano capsule equivalent diameter being related to is 2000 microns, and macro-scale is smaller.But specific surface area is very big, facilitates its fast endothermic And heat release.The capsule wall of Nano capsule is made of the macromolecule polymer material of excellent thermal conductivity, further strengthens reaction Heat transfer process when progress.The macromolecule polymer material does not react in cold compress patch range of temperature with two kinds simultaneously Any reaction occurs for object, guarantees that in cold compress patch mechanism, only physical change process occurs inside it for Nano capsule.Nanometre glue The laruyl alcohol in intracapsular portion and sad mixing material have biggish enthalpy of phase change, can absorb the heat of significant proportion.

Under normal temperature state, the phase-change material in Nano capsule is in liquid, constantly carries out as two chemical reagent react, Cold compress patch bulk temperature constantly reduces, after phase-change material condensation, since the caloric receptivity of reaction is greater than the caloric receptivity of phase-change material And the caloric receptivity summation by heat-absorbent surface, so cold compress patch bulk temperature continues to reduce.When reaction carry out to caloric receptivity with When the caloric receptivity of phase-change material and the equal caloric receptivity of heat-absorbent surface, cold compress patch bulk temperature is kept for one be lower than phase transition temperature Value a period of time.Later with the reduction of reactant unit time reaction mass, cold compress patch bulk temperature bottom out, in temperature During rise, the heat of Nano capsule absorbing reaction product slows down whole temperature recovery rate, when extending effective cold compress Between.

The insulation face be cold compress patch upper surface, shape be similar to ellipse (due to all use flexible material, so Specifically combine shape and be not fixed), select flexible foam plastic as non-heat-absorbent surface material, thermal coefficient is small, has bigger Intensity and flexibility, and do not chemically react, can be coexisted steadily in the long term with coolant.

The heat-absorbent surface is the lower surface of cold compress patch, is that the plane that thin flexible material is made into (guarantees that shape can be with Scald surface shape and change), which directly contacts with scald surface, referred to as heat-absorbent surface.

Compared to traditional cold compress patch, designed cold compress patch insulation face heat transfer totally caloric receptivity in accounting be 2.25%, it is basic it is believed that insulation completely, is much higher than remaining similar product.Most heats are exported through heat-absorbent surface, reach close Full utilization reaction generates purpose of the cooling capacity for cooling.

The small structure barrier material, i.e., scald can paste internal setting, it is for limited reactions rate, with small The partition-type structures in hole.Wherein overall configuration is inside and outside nesting type structure, and partition-type structures are cuboid-type, NH₄Cl solid powder dress In cuboid partition-type structures inside, Ba (OH)₂·8H₂O crystal powder is mounted between partition-type structures and insulating surface.In length The bottom surface of cube type partition-type structures and the aperture for having filling frangible plastic by lower half portion area distribution of side.It completes the process When, there is in these apertures the frangible plastic of filling to completely enclose aperture, two parts reactant separates completely.In actual use, Plastics in aperture are crumbed, NH₄Cl solid powder is along aperture flow direction outside and Ba (OH)₂·8H₂The mixing of O crystal powder is anti- It answers.Because of the quantity and limited diameter of aperture, therefore reaction rate is effectively controlled, and two reactants sufficiently can be mixed effectively, continues Endothermic heat of reaction externally generates cooling capacity, to achieve the purpose that reaction rate is controllable, cold compress patch persistently absorbs heat.

The fixing belt is the belt of cold compress patch two sides, which can be the structure similar to watchband, is also possible to The structure that can be placed directly against on skin similar to adhesive bandage two sides is also possible to be similar to " the magic that button is replaced on windcheater Patch ".

Compared with prior art, the utility model has the following beneficial effects:

First: using two kinds of endothermic reaction chemical reagent that can provide bigger endothermic heat of reaction amount under equal quality, for length Time cooling heat absorption provides prerequisite.

Second: in structure by the way of inside and outside nested, partition-type structures aperture, reaction can be effectively separated when unused Object, controlled in actual use by the apertures of partition-type structures it is anti-between the contact area control reactant between reactant Answer rate.

Third: the Nano capsule mixed between the reagents is reacting the initial stage carried out to reactant heat release, absorbs It reacts the cooling capacity generated and is stored in phase-change material, reduced so that cold compress patch passes to the cooling capacity at injury by heat-absorbent surface, Prevent frostbite caused by supercooling.With the reduction of reaction temperature, the solid-liquid phase change material inside Nano capsule is by the liquid under room temperature It is condensed into solid-state, stores cooling capacity.It carries out in reaction to the later period, cold compress patch temperature is gradually gone up, the solid-liquid phase change in Nano capsule It is liquid that material temperature, which rises or even melts, and heat is absorbed from reaction product, the whole temperature rise rate of cold compress patch is allowed to slow down, Be conducive to keep cold compress effect for a long time.And macroscopical small volume of nano particle, it is also opposite for the volume accounting of cold compress patch It is smaller, it will not influence the portability and miniaturization of cold compress patch.
