Description

Technical Field

[0001] The invention relates to the technical field of cold compress patches, and in particular to a cold compress patch with hydrogel. Background Art

[0002] Hydrogel cold compresses usually consist of three parts: a backing layer, a gel layer, and an anti-adhesive layer. The backing layer is generally a breathable and water-impermeable non-woven fabric that allows the gel layer to adhere to it while supporting heat dissipation and allowing the skin to breathe. The gel layer is the core part of the cold compress and is composed of water molecules, drugs, and a water-soluble polymer framework structure. It has temperature-sensitive permeability, membrane-controlled release, and moderate viscosity. The gel layer acts to dissipate heat by evaporation. When water evaporates at the application site, it absorbs surrounding heat, thereby reducing the local temperature. Hydrogel acts as a drug carrier, wrapping drug molecules in a network and delivering drugs to the skin through skin permeation to achieve percutaneous absorption and sustained-release drug delivery. However, the following problems are often encountered during actual use:

[0003] First, for example, when the elbow or knee joint is sprained and swollen, during the activity, the elbow or knee joint will constantly squeeze the gel layer, pushing the gel layer here to the surroundings, and then the original gel layer near the elbow or knee joint becomes thinner. The gel layer in the conventional hydrogel cold compress cannot recover in time, resulting in the inability to apply cold compress to the sprained part normally, and also hindering the rotation of the joint;

[0004] Secondly, when the temperature of the gel close to the cold compress area rises, it is necessary to transfer and replace the gel with the increased temperature in time, move the gel with the lower temperature to the cold compress area, and re-apply cold compress to the sprained area, but the existing cold compress patches are not designed for this purpose.

[0005] To this end, we designed a cold compress patch with hydrogel. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the gel layer in the conventional hydrogel cold compress cannot be restored in time, thus resulting in the inability to normally apply cold compress to the sprained part, and to propose a cold compress with hydrogel.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] Preferably, the secondary cold compress patch is connected to the side wall of the main cold compress patch via a twisted wire, and the secondary cold compress patch is attached to the skin via a pressure-sensitive adhesive.

[0010] Preferably, a plurality of first rubber blocking plates and a plurality of second rubber blocking plates arranged linearly are provided in the inner cavity, the plurality of first rubber blocking plates are arranged at the bottom of the inner cavity, the plurality of second rubber blocking plates are arranged at the top of the inner cavity, and the plurality of first rubber blocking plates and the plurality of second rubber blocking plates are arranged in a staggered manner.

[0011] Preferably, side panels are symmetrically arranged on both sides of the first rubber blocking plate, and the side panels are connected to the side walls of the second rubber blocking plate through a connecting elastic membrane, and the side panels and the connecting elastic membrane are used to separate the upper cavity and the lower cavity.

[0012] Preferably, a same curved elastic tube is inserted through the plurality of the second rubber baffle plates, and a plurality of flow holes are opened on the curved elastic tube.

[0013] Preferably, a plurality of water bags are provided in the upper cavity, and the water bags are against the top of the first rubber baffle plate, and the water bags are fixed to the top of the inner cavity.

[0014] Preferably, a plurality of glue holes are provided on the side panel, and an extrusion type silicone valve is provided in the glue holes.

[0015] Preferably, the plurality of water bags are disposed between two adjacent second rubber baffle plates, and the plurality of water bags are arranged linearly.

[0017] Preferably, a plurality of heat-conducting sheets for heat conduction are provided on the side of the primary cold compress patch and the secondary cold compress patch close to the water bag.

[0018] The beneficial effects of the present invention are:

[0019] 1. During the extrusion process of the present invention, the hydrogel with a lower temperature in the upper cavity will be squeezed into the lower cavity at a higher speed, allowing the hydrogel with a lower temperature to quickly squeeze into the hydrogel with a higher temperature, which can fully mix and cool the hydrogel with a higher temperature, and cool the hydrogel in the lower cavity close to the red and swollen area, thereby achieving a better cold compress for the red and swollen joints.

[0020] 2. The present invention provides a plurality of flow holes on the curved elastic tube, and the curved elastic tube is used to connect the hydrogel between two adjacent second rubber barrier plates. Such a configuration can also be used to connect the internal space of the entire upper cavity, that is, when the hydrogel in one area between the two second rubber barrier plates is squeezed and re-squeezed, part of the hydrogel will be driven to exchange the hydrogel material through the plurality of flow holes of the curved elastic tube, thereby being able to better cool the hydrogel entering the upper cavity.

[0031] Reference Figure 1-Figure 9 A cold compress patch with hydrogel comprises a main cold compress patch 1 and an adhesive bandage 3 arranged on the main cold compress patch 1 for fixing on the joints of the human body. It should be noted that when the patient's elbow or knee joint is sprained and redness and swelling appear, it is only necessary to apply the main cold compress patch 1 to the red and swollen area, and then tie or glue the adhesive bandage 3 to the skin, so that the main cold compress patch 1 is fixed and tightly attached to the red and swollen area.

[0032] Both the main cold compress patch 1 and the auxiliary cold compress patch 2 are provided with an inner cavity, and the main cold compress patch 1 and the auxiliary cold compress patch 2 are filled with hydrogel for cold compressing red and swollen joints, wherein the hydrogel is used to adhere to the red and swollen area to transfer the heat of the red and swollen area to the hydrogel, thereby completing the cooling effect on the red and swollen joints.

[0033] A plurality of auxiliary cold compress tapes 2 are arranged on both symmetrical side walls of the main cold compress tape 1. The auxiliary cold compress tapes 2 are connected to the side walls of the main cold compress tape 1 by twisted wires. Figure 1 In this state, the auxiliary cold compress patch 2 is flipped and tightly attached to the top of the main cold compress patch 1. The auxiliary cold compress patch 2 in this state fastens the two relative auxiliary cold compress patch 2 flipped on the top of the main cold compress patch 1 through the adhesive arranged at the end of the auxiliary cold compress patch 2. When needed, it is only necessary to tear open the two relative auxiliary cold compress patch 2, unfold the multiple auxiliary cold compress patch 2, and attach them to the red and swollen area through the pressure-sensitive adhesive, so as to achieve cooling and cold compress on the red and swollen area.

[0034] This arrangement can ensure that when the range of the redness and swelling area becomes larger, and the application range of the main cold compress patch 1 is not enough to cover the redness and swelling, the external auxiliary cold compress patch 2 is needed to perform derivative cold compress on the area that the main cold compress patch 1 cannot reach, and the auxiliary cold compress patch 2 is attached to the skin through pressure-sensitive adhesive, so that the derived auxiliary cold compress patch 2 will be close to the skin. It should be noted that when using the patch, the joint needs to be in a straight state, and then the main cold compress patch 1 is applied to the straight joint. At this time, the main cold compress patch 1 is attached to the straight red and swollen joint. In this way, the main cold compress patch 1 and the auxiliary cold compress patch 2 are squeezed when the joint moves, so that in subsequent joint activities, the main cold compress patch 1 and the auxiliary cold compress patch 2 are always close to the redness and swelling and continue to apply cold compress, and at the same time it will not hinder the normal rotation of the joint.

[0035] Conventional cold compresses are usually attached to joints. Due to the movement of the joints, the cold compresses will be constantly squeezed, which will cause the hydrogel in the cold compress to be squeezed to the surrounding areas by the joints. As the joints are repositioned, the hydrogel originally in the cold compress will not be repositioned. Therefore, as the joints continue to move, the hydrogel originally in the cold compress will be continuously pushed to diffuse around, but the pushed away hydrogel will not be repositioned, so a depression will appear where the cold compress is close to the joint, making it impossible to achieve a continuous cold compress effect.

[0036] To address this phenomenon, the present application document adopts a method for returning the hydrogel to its original position to reset the originally squeezed hydrogel. That is, after the active joint squeezes the hydrogel and the joint is reset, the area on the cold compress that was originally squeezed and depressed by the joint will be backfilled with the hydrogel that was pushed away. Therefore, the cold gel can be re-applied to the joint, making it easier to re-cold the red and swollen areas of the joint.

[0037] Reference Figure 3 and Figure 4 In this state, a plurality of first rubber blocking plates 4 and a plurality of second rubber blocking plates 5 arranged linearly are provided in the inner cavity, the plurality of first rubber blocking plates 4 are arranged at the bottom of the inner cavity, the plurality of second rubber blocking plates 5 are arranged at the top of the inner cavity, and the plurality of first rubber blocking plates 4 and the plurality of second rubber blocking plates 5 are staggered, that is, the first rubber blocking plate 4 is located between two adjacent second rubber blocking plates 5. When the joint moves, it will move against the first rubber blocking plate 4 toward the second rubber blocking plate 5, and at the same time, it will also drive the first rubber blocking plate 4 to move and squeeze the hydrogel in the inner cavity to move, thereby transferring the hydrogel that originally absorbed heat.

[0038] It should be noted that the hydrogel that absorbs heat from the red and swollen area will temporarily exist in some areas of the main cold compress patch 1 and the auxiliary cold compress patch 2. The hydrogel in the heat-absorbing area is close to the active joint and will transfer heat through flow, thereby cooling the heated hydrogel. Then, this cooled hydrogel is re-attached to the heated joint and continues to absorb heat.

[0039] Reference Figure 3 and Figure 4 State, the inner cavity is divided into an upper cavity and a lower cavity, and the lower cavity is attached to the human body joints, so that the hydrogel in the lower cavity will stick to the red and swollen joints and then absorb heat and reduce swelling of the heated red and swollen joints, while the hydrogel in the upper cavity is used as an auxiliary material replacement, allowing the hydrogels in the upper and lower cavities to achieve material replacement and cooling.

[0040] The specific operation of heat exchange in the upper and lower chambers is as follows:

[0041] Reference Figure 4In this state, the side panels 7 are symmetrically arranged on both sides of the first rubber barrier plate 4, so that during the joint movement, the main cold compress band 1 will be pushed close to one side of the skin, and then move against the first rubber barrier plate 4.

[0042] Reference Figure 5-Figure 8 Status, where Figure 5 and Figure 6 is not squeezed by the joints, and Figure 7 and Figure 8 In the state of being squeezed by the joint, the position of the main cold compress band 1 close to the joint is deformed, which will push the first rubber barrier plate 4 at the corresponding position to lift up, and at the same time, it will also drive the side panels 7 on the two side walls of the first rubber barrier plate 4 to lift up together. Since the side panels 7 are connected to the side walls of the second rubber barrier plate 5 through the connecting elastic membrane 8, the side panels 7 and the connecting elastic membrane 8 are used to separate the upper cavity and the lower cavity. Therefore, the first rubber barrier plate 4, the second rubber barrier plate 5, the side panels 7 and the connecting elastic membrane 8 form a partition component for separating the inner cavity, which is divided into an upper cavity and a lower cavity arranged up and down, and the setting of the connecting elastic membrane 8 can prevent the hydrogel from flowing between the side panels 7 and the second rubber barrier plate 5.

[0043] When the first rubber barrier plate 4 is lifted together with the side plates 7 on both sides, the space of the upper cavity shrinks and the space of the lower cavity expands, which causes the side plates 7 to squeeze the hydrogel in the upper cavity, thereby exchanging the hydrogels in the upper cavity and the lower cavity.

[0044] It should be noted that during the exchange of the hydrogels in the upper chamber and the lower chamber, the specific process is as follows:

[0045] The side plate 7 is provided with a plurality of glue holes 9, and the glue holes 9 are provided with extrusion-type silicone valves. The setting of the extrusion-type silicone valves can not only block the flow of hydrogel in the upper and lower cavities when the joint is in a non-bending state, so that the hydrogel in the upper and lower cavities is in a two-layer space, but also effectively avoid direct contact between the hydrogel in the upper and lower cavities due to the obstruction of the extrusion-type silicone valves, so that the hydrogel in the upper and lower cavities can only be mixed by passing through the extrusion-type silicone valves through the glue holes 9 to achieve heat exchange and conduction;

[0046] This arrangement allows the higher temperature hydrogel originally located in the lower cavity to mix with the lower temperature hydrogel in the upper cavity, that is, the lower temperature hydrogel in the upper cavity is squeezed into the lower cavity from the extrusion type silicone valve of the glue hole 9 under the extrusion action of the side plate 7. Since both sides of the second rubber barrier plate 5 have side plates 7 with glue holes 9, both sides of the second rubber barrier plate 5 enter the lower cavity below the second rubber barrier plate 5 through the glue holes 9 under the action of extrusion. During the extrusion process, the lower temperature hydrogel in the upper cavity will be squeezed into the lower cavity at a higher speed, allowing the lower temperature hydrogel to quickly squeeze into the higher temperature hydrogel, which can fully mix and cool the higher temperature hydrogel with the lower temperature hydrogel, cool the lower cavity hydrogel close to the red and swollen area, and better cool the red and swollen joints.

[0047] The first rubber barrier plate 4, the second rubber barrier plate 5, the side plate 7 and the connecting elastic membrane 8 are all made of heat-insulating materials to avoid heat transfer caused by indirect contact between the hydrogels in the upper cavity and the lower cavity, that is, to achieve temperature isolation of the hydrogels in the upper cavity and the lower cavity, so that the temperature exchange of the hydrogels in the upper cavity and the lower cavity can only be completed by squeezing the hydrogels into the lower cavity through the glue holes 9 to cool the hydrogels in the lower cavity.

[0048] Furthermore, a plurality of water bags 6 are provided in the upper cavity, and the water bags 6 are against the top of the first rubber baffle plate 4, and the water bags 6 are fixed at the top of the inner cavity, referring to Figure 4 and Fig. 9 As shown in the state, a plurality of water bags 6 are independently arranged and fixed in the upper cavity between two adjacent second rubber baffle plates 5.

[0049] During the process of joint flexion and then extension, the movement trend of the components inside the cavity is as follows:

[0050] When the joint is bent, the water bag 6 abuts against the top of the first rubber baffle plate 4, so the first rubber baffle plate 4 pushes and squeezes the water bag 6, causing the water bag 6 to deform. The water bag 6 is made of an elastic plastic bag with a water body inside. Figure 6 becomes Figure 8 state.

[0051] It should be noted that at this time, after the hydrogel with a lower temperature originally located in the upper cavity is squeezed into the lower cavity, as the joint stretches, the first rubber barrier plate 4 will be pushed by the water bag 6, and at the same time, the elastic membrane 8 will restore the first rubber barrier plate 4. Therefore, the side plate 7 will squeeze the hydrogel located in the lower cavity under the action of the first rubber barrier plate 4, so that a part of the mixed hydrogel after cooling can be separated and re-enter the upper cavity through the glue hole 9 on the side plate 7.

[0052] Among them, multiple water bags 6 are arranged linearly, and multiple thermally conductive sheets for heat conduction are provided on the side of the main cold compress patch 1 and the auxiliary cold compress patch 2 close to the water bag 6. It should be noted that the setting of the water bag 6 can not only reset the first rubber barrier plate 4, but also can contact and cool the hydrogel re-squeezed into the upper cavity, that is, the hydrogel squeezed into the upper cavity will produce heat conduction after contacting with the water bag 6, and the temperature of the hydrogel re-squeezed into the upper cavity will be conducted to the water bag 6, so as to realize the temperature transfer and complete the cooling effect of the hydrogel in the upper cavity, and at the same time prepare the cooling for the hydrogel in the upper cavity to be squeezed into the lower cavity again. At the same time, the setting of the thermally conductive sheet can timely conduct the heat of the hot water body in the water bag 6 through the thermally conductive sheet to complete the cooling of the water bag 6.

[0053] It should be noted that the same curved elastic tube 10 is inserted through the multiple second rubber barrier plates 5, wherein the setting of the curved elastic tube 10 can not only drive the main cold compress band 1 to return to its original state after the joint is repositioned to be straight, and then drive the first rubber barrier plate 4 to be repositioned, but also because the curved elastic tube 10 is provided with multiple flow holes, the curved elastic tube 10 is used to connect the hydrogel between two adjacent second rubber barrier plates 5. Such a setting can also be used to connect the internal space of the entire upper cavity, that is, when the hydrogel in one area between the two second rubber barrier plates 5 is squeezed and re-squeezed, part of the hydrogel will be driven to exchange the hydrogel substance through the multiple flow holes of the curved elastic tube 10, thereby being able to better cool the hydrogel entering the upper cavity.

[0054] It should be noted that the multiple temperature conduction and multiple cooling zone settings adopted in the present application scheme can effectively improve the efficiency of cooling and cold compressing red and swollen joints, so that the cooling process can realize multiple transfers of high-temperature hydrogel and contact with the water bag 6, and the setting of connecting the upper cavity through multiple flow holes on the curved elastic tube 10 can realize the transfer of the hot area of ​​the red and swollen joints and the part of the lower cavity that is closely adjacent to the corresponding one to the corresponding upper cavity, and then the substance is transferred through the hydrogel extrusion of the curved elastic tube 10, so that the hydrogel in the entire upper cavity is a heat-conducting medium, that is, part of the heat in the lower cavity is transferred to the entire upper cavity, and then cooled by multiple water bags 6, thereby improving the cooling efficiency, and the lower cavity composed of the modular first rubber baffle plate 4 can also prevent the rotation of the joint from being affected.

[0055] The working principle of the present invention is as follows:

[0056] When the patient's elbow or knee joint is sprained and red and swollen, it is only necessary to apply the main cold compress tape 1 to the red and swollen area, and then tie or glue the adhesive bandage 3 to the skin, so that the main cold compress tape 1 is fixed and tightly attached to the red and swollen area. When the red and swollen area is large, when necessary, it is only necessary to tear open the two relative auxiliary cold compress tapes 2, unfold multiple auxiliary cold compress tapes 2, and attach them to the red and swollen area through the pressure-sensitive adhesive, so as to achieve cooling and cold compressing of the red and swollen area;

[0057] When the joint moves, it will move against the first rubber blocking plate 4 toward the second rubber blocking plate 5, and at the same time, it will drive the first rubber blocking plate 4 to move and squeeze the hydrogel in the inner cavity to move, thereby transferring the hydrogel that originally absorbed heat, that is, the hydrogel in the lower cavity will cling to the red and swollen joint and absorb heat and reduce swelling of the heated red and swollen joint;

[0058] During the extrusion process, the hydrogel with lower temperature in the upper cavity will be squeezed into the lower cavity at a higher speed. The lower temperature hydrogel will be quickly squeezed into the higher temperature hydrogel, which can fully mix and cool the higher temperature hydrogel with the lower temperature hydrogel, thereby cooling the lower cavity hydrogel close to the red and swollen area and providing better cooling for the red and swollen joints.

[0059] The hydrogel re-squeezed into the upper cavity is subjected to contact cooling, that is, heat conduction is generated after the hydrogel squeezed into the upper cavity contacts with the water bag 6, and the temperature of the hydrogel re-squeezed into the upper cavity is conducted to the water bag 6, thereby realizing the temperature transfer and completing the cooling effect of the hydrogel in the upper cavity. At the same time, the hydrogel in the upper cavity is prepared for cooling when it is re-squeezed into the lower cavity. At the same time, the setting of the heat conductive sheet can timely conduct the heat of the heated water body in the water bag 6 through the heat conductive sheet, thereby completing the cooling of the water bag 6.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
