Description

Compression pads which has a thermal sensitive melting / solidifying filler by reversible cycle

The present invention makes a pad made of an elastic membrane using the properties of a hydrocarbon compound that solidifies below a specific temperature and melts above a specific temperature as a filler, and heats or cools it with a thermoelectric element so that both high-temperature relaxation baths and low-temperature compression fastenings can be used. It is a unit block expandable wound compression device that can repeat branch first aid.

When direct current is applied to the pn junction structure of hetero semiconductors (usually bismuth and tellurium (Bi2Te3)), the thermoelectric power, that is, the Peltier effect, occurs at the bonded site, and one side is cooled and one side is heated according to the current direction. Thermoelectric elements have a very rapid rate of change of temperature and a large heat capacity per unit volume, making the compact design easy. Therefore, it is widely used in various small cold and hot appliances and cold pad pads.

Documents (1) and (2) introduce a typical endothermic and heat dissipating structure for using a thermoelectric element as a commercially available cold / hot steamer. However, they are all close to small refrigerators and are difficult to use outdoors (eg, sports stadiums) and are not applicable to various affected areas.

Literature (3) is somewhat distance from the emergency pressure treatment function pursued in the present invention, but using the same heat dissipation effect, so that when the heat to the head, such as heat cold to the cold element for a long time to heat cold Combined with a heat dissipation cooler. Considering the weight of conventional fans and heat carriers (heat pipes, cooling fins, etc.), it is a considerable weight that can be burdened on the head, and the actual cooling effect is not large because the lower cold and upper heat are mixed through pads wrapped up and down. .

Literature (4) also introduces a pressure pad structure conceptually similar to the present invention, which is a hinge (flexible) and is arranged on the thermoelectric element a heat sink for cold pack. However, since the heat transfer / heat shield structure of the pad or the thermoelectric element is not specific, it is difficult to substantially maintain the desired high / low temperature state for the body contact surface.

Literature (5) is published earlier than Literatures (3) and (4), but is more practical and aims at a hair cooling machine of a weak cooling type with a small cooling load. While the heating and cooling loads required at the body contact surface are not large, the auxiliary devices for exothermic / absorption are sufficient, so the function of weak cooling and weak heat insulation is sufficiently exerted.

Paraffin is a material that achieves certain mechanical properties while reciprocating between a liquid state and a solid state with temperature. Paraffin, a hydrocarbon-based compound, exhibits various melting points depending on the degree of purification and components, and usually ranges from 47 to 65 ° C.

The straight-chain paraffinic hydrocarbon molecular formula is CnH2n + 2 or CH3 (CH2) nCH3, which is mainly contained in the oil of heavy oil, and is obtained by applying pressure to the cooled precipitate. It is used as a raw material for candles, electrical insulating materials and crayons. Flowable paraffin, a well-refined fraction of lubricating oil obtained from petroleum, is a colorless, less volatile, almost odorless liquid. It is also used as a base for ointments and suppositories.

Document (6) relates to a temperature-sensitive shape deformation jig (Jig) that suitably utilizes the liquidity and solid phase strength of paraffins. It introduces the structure that the jig guide piece can be easily moved according to the work of various shapes by melting and re-solidifying the paraffin placed on the pedestal.The temperature response does not require much force because the fixed direction of the jig and the flow direction of paraffin are vertical. Sufficient performance is shown by the type of deformable parts.

Human bones, joints, and ligaments that are damaged by external shocks and by aging can vary in appearance as well as in the form of damage. Most emergency treatments that can be performed before orthopedic surgery include cold fixation of the affected area using splints or bandages, and cold compresses that relieve inflammation and swelling of the affected area. In addition, after surgical treatment of the affected area and swelling and inflammation go away, the method of warming the affected area gently for a long time to improve blood flow and activate cells is widely used. In an emergency, the cast is made of only a pressure bandage, and the cold pack and the hot pack are used as ice packs or hot packs using electric heating elements separately from the cast material. Therefore, it is applicable to all kinds of affected areas, and a combined first aid device that enables both cold compression and warm relaxation has not been developed yet.

On the other hand, as mentioned above, the thermoelectric element itself has a considerable heating and cooling capacity, but due to the nature that heat and cold are released at the same time, the heat exchanges unwanted heat or heat generated from the opposite side to the outside (heat dissipation / heat absorption). You need to remove it.

However, in the prior art, the entire system was complicated and enlarged in the heat exchange process, and thus the field was inferior. Therefore, the thermoelectric element was not very practical as a first aid heating / cooling tool.

In other words, the conventional pad pad using a thermoelectric element is not easy to achieve good performance at the same time in both heating and cooling functions. In particular, in case of cooling the affected part by using thermoelectric element, if you want to perform the heat dissipation action of the opposite thermoelectric element at room temperature, the temperature of the radiating fin increases significantly and accordingly the cooling temperature of the contacted part of the affected part also increases. Unless combined, pure natural heat dissipation alone is not easy to reduce the cooling temperature.

Likewise, there is no practically better means for emergency fixation of the affected part when a fracture, severe sprain, or dislocation occurs, except for compression bandages or gypsum casts based on splints, all of which are shaped and fixed to fit the affected area. It took so much time that emergency use was impossible. Moreover, the method of combining the cooling function that helps to alleviate inflammation as well as the compression fixation of the affected part is not considered at present.

The present invention was devised to overcome the respective limitations of use each of the conventional wound compression first aid device, inflammation relief cold pack device and blood circulation improving hot pack device as described above, convenient and powerful for specific purposes It is designed to meet the molding speed, ease of molding, and strength after molding necessary for the compression function and the relaxation of the affected area at once, and to perform the cold and hot maintaining functions that can perform cold and hot compress on the fly according to the affected condition all with one device. .

In order to achieve the above object, the present invention is a filler (filler), which is an intermediate material that first presses the body part and transmits cold and heat, and has a temperature sensitive property of repeating melting and solidification according to a set temperature. Was used. The filler is basically a filler having a melting point of 50 ~ 60 ℃ range, it is possible to use a mixture of stearic acid, NaOH and TEA in the soap base. Important criteria for the selection of these are melting temperature and melting time. Basically, the hardness of solidification is high when considering the compression function of first aid and cold treatment. Sufficient viscosity) is suitable. In the present invention, these fillers are all filled in the thin elastic membrane 11 in the form of a bag to come into contact with the thermoelectric element 12 and may be replaced as necessary. Another important factor in the selection of fillers is that the low vapor pressure in the molten state (low volatility in the liquid state) prevents the formation and inflation of gas inside the elastic membrane during the melting and solidification process in a confined space. Is the point.

Considering the above, the material that satisfies all the necessary strength, viscosity, melting point, low vapor pressure, and low specific heat is an increase in the amount of stearic acid and NaOH in the soap base and additionally added a little TEA.

Preferably, 90% soap base weight ratio of stearic acid weight ratio of 9%, NaOH weight ratio of 1%, TEA weight ratio of about 1% may be mixed.

The chemical background using these mixtures is that the addition of stearic acid and NaOH causes the two substances to react to form sodium styrene, which lowers the specific heat significantly and gives a solid high strength.

Since the added stearic acid and NaOH will react in the soap base, it can be replaced by adding a mixture of sodium styrene in advance.

The carboxylic group (~ COOH moiety at both ends of the chemical structure) of the ~~ acid bases in the soap base ingredient table helps to form hydrogen bonds, increasing viscosity and lowering vapor pressure. In addition, the large dispersibility due to the large molecular weight of the four fatty acids also contributes to high viscosity and low vapor pressure.

In addition, when a substance called tri-ethanolamine (TEA) is added from the outside, the viscosity is greatly increased by forming many hydrogen bonds by three hydroxyl groups in the chemical formula structure of TEA.

With each of these properties, the mixture of soap base + stearic acid + NaOH + TEA can have the desired melting point, high viscosity, low specific heat, low vapor pressure and high strength in solid state.

Heating or cooling the thermosensitive filler is a thermoelectric element 12 and is utilized in the present invention in a flat form. When the thermoelectric element is operated in the heating mode, the filler melts and the elastic membrane (11) pocket containing the same turns into a flat, wide, flexible pad for heating. On the contrary, when the thermoelectric element is operated in the cooling mode, the filler is hardened and contains the elastic membrane ( 11) The pouch can be converted to a thick, narrow, hard pad for cold pressing.

Of course, in the process, before the filler is solidified, it is molded to fit the complicated three-dimensional shape of the affected part in a flexible state, and if the temperature is solidified after the solidification, the solidified shape does not collapse even when pressurized with considerable force. It is a basic effect.

Meanwhile, the main plate 30 and the insulating frame 20, which are designed to have an intentional and appropriate thickness, are introduced as a main body structure that properly couples the thermoelectric element, the elastic membrane, and the filler, and thermally isolates the filler and the opposite side of the filler. . Since the main plate 30 is thin, has good thermal conductivity and good rigidity, a metal material (preferably aluminum alloy) is suitable. Since the insulating frame 20 serves as a main plate of the lower portion and at the same time serves to thermally isolate the upper and lower surfaces of the thermoelectric element is preferably made of a ceramic material and designed to be thicker enough than the main plate.

Since the elastic membrane 11 is made of synthetic rubber or low density polyethylene (wrap material), the elastic membrane 11 may be sandwiched between the plate and the frame to be fixed and adhered to the metal plate or the ceramic frame, and be pressed and fixed by the fastening screw 60. Accordingly, the filler 10 filled therein exhibits a useful function while reversibly solidifying and melting at various temperature ranges while maintaining sufficient airtightness regardless of the solid-liquid state.

The metal main plate 30 having a thin thickness can effectively transfer heat or cold air (heat or cold air to the opposite side of the filler) to the heat exchanger 40 on the opposite side of the skin compression, and the heat exchanger 40 is unnecessary to heat. Or quickly dissipate cold air around.

In the case of using a thermoelectric element, since only a slight temperature rise is required compared to the body temperature, there is no problem in the heat exchanger dissipating unnecessary cool air quickly through the surrounding air, which is widely used in the prior art. However, the problem is that in the case of cold compresses using thermoelectric elements, when the affected part compression apparatus of the present invention is used for emergency compression fixation of the affected part with cold compresses, it is relatively low that reaches a range of about 5 ° C. to 10 ° C. only by natural convection at room temperature. The temperature is realized, and in case of emergency lowering the exothermic temperature of the heat exchanger (40) by fan or fan in an emergency, it is possible to be below zero temperature.

The cold temperature range of about 5 ℃ ~ 10 ℃ obtained without additional convection cooling in the above obviously can not exert the same effect as ice. However, since the filler of the present invention and the pad using the same harden into a shape that perfectly fits the shape of the affected part at the corresponding temperature, the effect of fixing and compressing the affected part is obvious and more importantly, the cold pack effect in an emergency is more important. Since the distance between the heat exchanger 40 and the affected part is not sufficiently pressed by the molding characteristics of the temperature-sensitive filler, the distance is sufficiently far, so that side effects caused by insufficient heat dissipation of the heat exchanger (cold-heat mixing) can be effectively prevented. Is that there is. This point corresponds to the useful and unique technical characteristics of the present invention which are differentiated from the prior art.

Meanwhile, the main plate 30 serving as a platform supporting all of the various components may be extended to two or more sheets and may be freely bent to implement a complex multi-stage curved surface. In addition, the binding belt 27 is added to the human body so as to apply a strong pressure irrespective of the coupling angle of the main plate to enable the cooling compression of the affected part even when the filler 10 is hardened. At this time, since the thermoelectric element can realize a complicated operation mode by the basic DC power supply alone, the configuration of the connection wire 51 and the adapter or the battery 50 and the configuration of the power plug 52 as the power supply are conventional technical configurations. Suffice.

The present invention has an advantage of further having a pressure fixing function of the affected part which a conventional thermoelectric pad does not have by using a filler that melts softly and hardens with temperature. In addition, the melted filler is instantly molded into a shape that fits into the wound shape while the temperature is firmly fixed while lowering the temperature, so it can be perfectly applied to complex joints such as ankles, knees, and shoulders. Can be added.

This instant molding function is reversible at any time according to the temperature change, which is combined with the operating characteristics of the thermoelectric element, which has a very fast heating and cooling rate, to enable very quick first aid regardless of the shape and position of the affected part. For example, if the cast is temporarily cast on the fractured part, it is possible to use it flexibly to raise the temperature immediately and re-cast it. After that, if the proper cooling state is maintained, the affected part can be fixed for a long time.

Finally, even if the heat exchanger 40 for extracting heat from the opposite side of the thermoelectric element proceeds to dissipate at room temperature, the elastic membrane is not pressed down sufficiently due to the molding characteristics of the filler, that is, the affected surface and the thermoelectric body. Since the device is kept away from each other, the filler can be kept out of the heat dissipation range of the heat exchanger for a long time, and the cold pressure function can be exerted by simply blowing a fan at the first aid site. It works.

With reference to the embodiment of the present invention included in the drawings in order to technically support the above-described solution of the present invention will be described in detail.

However, in the following embodiments, the components including the specific terminology and combinations thereof do not limit the technical spirit inherent in the present invention.

First, the components of the filler 10 having material properties important for the present invention will be described.

The key to filler selection is the melting point and melting rate, and the absolute melting point depends on the chain shape of the hydrocarbon CH. Of course, the melting and solidification time of the entire filler will depend on the specific heat and total amount of the filler and the thermal capacity of the thermoelectric element.

Filler 10 is a material having a melting point of 50 ~ 60 ℃ range, is a soap base material consisting of a mixture of stearic acid, NaOH and TEA in the soap base. The addition of stearic acid (9% by weight) and NaOH (1% by weight) lowers the specific heat of the soap base and improves its hardness when hardened. The addition of TEA (weight ratio 1%) contributes to an increase in viscosity.

Other materials that may be used as the filler of the present invention are as follows.

non-adecyl-cyclo-hexane

1,2,3-heptan-etriol

trans-1,2-Cyclo-pentane-diol

1,2-Ethane-diol, didodecanoate

2-Ethyl-2-nitro-1,3-propane-diol

4-tert-Butyl-1,2-benzene-diol

2-Butyne-1,4-diol

Of these, 4-tert-butyl-1,2-benzenediol is flammable and abnormal in the respiratory system when inhaling steam, so it is preferable not to use it unless a temperature range that can be accurately implemented only with the above materials is required.

On the other hand, the amount of filler is proportional to the molding time of the elastic membrane 11 pocket, and the time can be shortened by rapidly cooling or rapidly heating the thermoelectric element. For cold compressing or cold pressing, the filler 10 is completely melted, and then the elastic membrane 11 pocket is drooped down sufficiently, and then gradually hardens from the filler 10 close to the thermoelectric element 12 while initiating cooling of the thermoelectric element. . As a result, the user can use the annular compression mechanism in a state sufficiently separated from the heat generating portion of the heat exchanger 40 above the thermoelectric element, and the effect of the additional cooling mechanism such as a fan is further increased. (See Figure 6)

In the case of the heat pack, the opposite is true, but usually no pressure is attempted in the heat situation. Therefore, the melted and fluidized filler when heated helps to cover the affected area. As shown in FIG. 10, the liquid filler spreads flat in the elastic membrane to cover the affected part broadly and gently. In this process, the sufficient thickness of the insulating frame 20 serves to prevent inadvertent burns by the thermoelectric element.

Meanwhile, the elastic membrane 11 serving as a molding bag containing a filler may be selected from among low density polyethylene or synthetic rubber having a glass transition temperature of −10 ° C. or lower and a melting point of 90 ° C. or higher. In either case, sufficient elasticity should be exerted over a wider range than the actual service temperature of the filler it contains.

For reference, after the initial filler heating of FIG. 6, the thermoelectric element is relatively cooled by the heat exchanger 40 due to the reaction caused by the heating. It can be cooled rapidly. Therefore, the filler 10 in the sagging elastic membrane bag can be rapidly cooled from the upper part far from the affected part to solidify the upper part of the filler first before solidification proceeds sufficiently at the part contacting the lower part. Therefore, as shown in FIG. 8, in the cold compression use mode, molding is possible according to the annular shape, but the pad is thick enough to be relatively less affected by heat generation of the heat exchanger. This has the advantage that it is much easier to maintain the temperature unbalance (cold affected area and hot pad surface state) than the conventional thin pad using a thermoelectric element.

Specific embodiments of the wound compression mechanism (unit unit 3 plate in series) of the present invention will be described in detail with reference to Figs.

The overall appearance is a compact design of the heat dissipation part in the pad of the pad that uses the thermoelectric element as a heat generating and endothermic source, and is produced in a multi-plate form.

The adapter 50 for supplying power to the thermoelectric element 12 through the plug 52 (to the respective thermoelectric element through the wire 51) can change the household AC power into a DC power of 9V to 12V. In this process, it is possible to change the direction of current by simple button operation. Of course, the adapter 50 may also be replaced by a DC battery and its control device. It is necessary to supply a DC power supply with an appropriate amount of current so that the current direction can be easily changed, which can be appropriately modified by a person skilled in the art as needed.

In the present invention, the annular compression mechanism may be composed of several sheets, but the central configuration of the skeleton in one of the unit blocks (unit pad-type annular compression mechanism) serves as the main plate 30 and the lower fixing frame serving as the upper plate. The insulation frame 20 is.

The main plate 30 and the insulating frame 20 are each composed of a combination of two or more triangular or rectangular plates, each insulating frame 20 is coupled by a hinge 31 so as to be rotatable with each other, The binding port 32 is further formed on the edge portion so as to be bound to the human body at various angles and sizes, and the binding belt 33 is further coupled to the opposite edge of the hinge 24.

The thermoelectric element 12 is seated toward the skin pressing surface of the main plate 30, and the heat exchanger 40 is coupled in a contact tightening manner toward the skin pressing opposite surface. The insulating frame 20 is coupled to the main plate 30 through the fastening screw 60, and surrounds and fixes the thermoelectric element 12.

In this case, the elastic membrane 11 may also be firmly coupled by the fastening action of the fastening screw. Specifically, an edge portion of the elastic membrane bag is inserted between the main plate 30 and the insulating frame 20 and coupled in a bag shape. .

The temperature sensitive filler 10 described in detail above is filled in the space formed by the elastic membrane 11 and the thermoelectric element 12 to transfer hot or cold air of the thermoelectric element 12 to the outside of the elastic membrane. .

At this time, the filling volume of the filler 10 should be larger than the sum of the volumes of each of the main plate 30, the thermoelectric element 12, and the insulating frame 20, based on the time of melting. This is because when the size of the membrane 11 is too small, a gap may occur in the pressing portion, and a distance between the affected portion and the main plate may be closer, which may interfere with cold air or heat emitted from the upper heat exchanger 40.

The heat exchanger 40 is composed of at least three convective heat exchange plates 42 and heat pipes 43 and heat transfer plates 41 supporting them, wherein the heat transfer plates 41 are formed in the main plate 30. It is preferable that the contact area between the heat transfer plate and the main plate is larger than the area of the thermoelectric element 12 in contact with the skin pressure opposite surface.

The design considering the effective heat transfer is also reflected in the thickness of the main plate 30 and the insulation frame 20. In general, the main plate 30 may be a thin metal plate material, and the insulating frame 30 may be a thick ceramic material. Since the two frames are forcibly fastened by the fastening screw 60, it is preferable to select the optimal material considering the thermal conductivity or the thermal insulation performance rather than the adhesive force between them, and at least the main part of the part in contact with the thermoelectric element 12 and the heat transfer plate 41. The thickness of the plate 20 should be very thinner than the thickness of the insulating frame 20 in consideration of thermal conductivity. In other words, the thickness of the portion surrounding the edge of the thermoelectric element 12 in the insulating frame 20 should be very thicker than the thickness of the main plate 30.

Preferably, the palm unit unit plate, the thin portion is set to about 3mm in thickness, and considering the fit, the insulation frame is set to about 15mm in thickness to leave a sufficient thermal conduction distance difference of about five times or more.

7 to 8 are side views showing the shape of the filler and the elastic membrane when using the affected part compression apparatus of the present invention in the hot and cold pressed state, respectively. The size of the elastic membrane bag during the hot spring spreads wide enough to the hinge 31 instead of thinning it can be evenly steamed over a wide area without empty space. This is generally consistent with the shape of the affected area where hot compresses are required. Likewise, the size of the elastic membrane bag during cold pressing (splashing) is relatively narrow, rather than maintaining a thick height, so that each unit pad using the hinge 31 can be narrowly bent. Therefore, it is very optimal for narrow areas where orthopedic accidents such as ankles, knees, wrists and elbows occur a lot, cools the affected areas and compresses the sprains. Of course, this process prevents the dislocation or fracture from further progressing because it is molded immediately into a rigid shape that fits the shape of the affected part.

Figures 9 to 11 are various cold press expansion use state diagram of the present invention compression device and Figures 12 to 14 are various hot compress expansion use state diagram of the present invention compression device. By using a variety of coupling methods of the fastener 32 can be made in a very complex shape on the fly and tight tightening through the fastening belt 33 is critical for cold pressing of the complex and narrow affected area. In this process, the volume of filler contained in each bag is divided into elastic membrane bags and suitable amount separately, which is an important requirement for the emergency configuration of the wound compression device in a complicated shape.

While the embodiments of the present invention have been described in detail with reference to the drawings, the technical spirit of the present invention is not limited to the above embodiments.

In other words, one of ordinary skill in the art to which the present invention pertains may implement a simple change and a simple extension case that are not included in the specification and the drawings by utilizing the technical spirit of the present invention. It is obviously included in the scope of the invention expressed by the claims of.

The present invention is described based on the plate-shaped main plate coupling structure, but the shape of the plate is variously modified into a curved plate shape or a donut shape, if necessary, forced cooling using a refrigerant hose instead of a heat exchanger attached to the upper plate If the structure is changed, it can be very effectively used as a surgical site fixation device during the emergency operation of complex fracture accidents for difficult fixation. Of course, even in this case, the inherent technical idea of the present invention, which realizes precise molding and perfect cold and hot pressing simultaneously while gradually solidifying in the state of maintaining sufficient distance from the surgical site surface and the thermoelectric element by the temperature-sensitive filler, is fully utilized.
