Description

Technical Field

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

[0002] A hydrogel cold compress patch usually consists of three parts: a backing layer, a gel layer, and a non-stick layer. The backing layer is generally a breathable and waterproof non-woven fabric that can attach the gel layer to it, support heat dissipation at the same time, and enable the skin to breathe. The gel layer is the core part of the cold compress patch, which is composed of water molecules, drugs, and a water-soluble polymer framework structure, and has the functions of temperature-sensitive penetration, membrane-controlled release, and moderate viscosity. The function of the gel layer is to dissipate heat by evaporation. When the water evaporates at the application site, it will absorb the surrounding heat, thereby reducing the local temperature. As a drug carrier, the hydrogel encapsulates drug molecules in the network and transports the drugs into the skin through skin penetration to achieve the effects of transdermal absorption and sustained-release drug delivery. However, the following problems often occur during actual use:

[0003] First of all, for example, when the elbow joint or the knee joint is sprained and swollen, during the movement process, the elbow joint or the knee joint will continuously squeeze the gel layer, pushing the gel of the gel layer here to the surrounding areas. As a result, the thickness of the original gel layer near the elbow joint or the knee joint becomes thinner. The gel layer in the conventional hydrogel cold compress patch cannot be restored in time, which leads to the inability to normally perform cold compress on the sprained part, and at the same time, it will also hinder the rotational movement of the joint.

[0004] Secondly, when the temperature of the gel close to the cold compress area rises, it is necessary to timely transfer and replace this part of the gel with increased temperature, let the gel with lower temperature move to the area close to the cold compress, and re-perform cold compress on the sprained part. However, the existing cold compress patches are not designed for this.

[0005] Therefore, we have 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 patch cannot be restored in time, resulting in the inability to normally perform cold compress on the sprained part, and to propose a cold compress patch with hydrogel.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A cold compress patch with hydrogel, comprising a main cold compress patch band and an adhesive strap arranged on the main cold compress patch band for fixing at a human joint. A plurality of secondary cold compress patch bands are arranged on both symmetric side walls of the main cold compress patch band. Inner cavities are provided in both the main cold compress patch band and the secondary cold compress patch bands, and each inner cavity is divided into an upper cavity and a lower cavity. The lower cavity adheres to the human joint. The main cold compress patch band and the secondary cold compress patch bands are filled with hydrogel for cold compressing the swollen joint part.

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

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

[0011] Preferably, side plates are symmetrically arranged on both sides of the first rubber partition plate, and the side plates are connected to the side walls of the second rubber partition plates through connecting elastic membranes. The side plates and the connecting elastic membranes are used to separate the upper cavity and the lower cavity.

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

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

[0014] Preferably, a plurality of glue-penetrating holes are formed in the side plates, and extrusion-type silica gel valves are arranged in the glue-penetrating holes.

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

[0016] Preferably, the curved elastic tube is used to communicate the hydrogel between two adjacent second rubber partition plates.

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

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

[0019] During the extrusion process of the present invention, the hydrogel with a lower temperature in the upper cavity will be extruded into the lower cavity at a higher speed, allowing the hydrogel with a lower temperature to quickly enter the hydrogel with a higher temperature. This can play a role in fully mixing the hydrogel with a higher temperature and the hydrogel with a lower temperature and reducing the temperature, cooling the hydrogel in the lower cavity close to the red and swollen area, and achieving better cold compress on the red and swollen joint.

[0020] In the present invention, a plurality of flow holes are provided on the curved elastic tube, and the curved elastic tube is used to connect the hydrogel between adjacent two second rubber barrier plates. Such a setting can also be used to connect the internal space of the entire upper cavity. That is, when the hydrogel located between two second rubber barrier plates in one area is extruded and re-entered, it will also drive part of the hydrogel to exchange hydrogel substances through the plurality of flow holes of the curved elastic tube. Therefore, it can better cool the hydrogel entering the upper cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Refer to Figures 1-9 , a cold compress patch with hydrogel, including a main cold compress patch band 1 and an adhesive binding band 3 arranged on the main cold compress patch band 1 for fixing at the human joint. It should be noted that when the elbow joint or knee joint of a patient is sprained and swollen, only need to apply the main cold compress patch band 1 on the swollen area, and then tie or paste the adhesive binding band 3 on the skin, so that the main cold compress patch band 1 is fixed and closely attached to the swollen area.

[0032] Inner cavities are provided in both the main cold compress patch band 1 and the sub cold compress patch band 2, and the main cold compress patch band 1 and the sub cold compress patch band 2 are filled with hydrogel for cold compressing the swollen joint part. Among them, the hydrogel is used to be attached to the swollen area, transfer the heat of the swollen part to the hydrogel, and then complete the cooling effect on the swollen joint.

[0033] A plurality of sub cold compress patch bands 2 are arranged on both symmetric side walls of the main cold compress patch band 1. The sub cold compress patch bands 2 are connected to the side wall of the main cold compress patch band 1 through twisted wires. Before use, such as Figure 1 state, the sub cold compress patch bands 2 are in a state of flipping and closely attaching to the top of the main cold compress patch band 1. In this state, the sub cold compress patch bands 2 at the ends of the sub cold compress patch bands 2 are buckled by the adhesive provided at the ends of the sub cold compress patch bands 2. When needed, only need to tear the two opposite sub cold compress patch bands 2 and unfold the plurality of sub cold compress patch bands 2, and attach them to the swollen area through pressure-sensitive adhesive, so as to realize the cooling cold compress on the swollen area.

[0034] Such a setting can ensure that when the swollen area becomes larger and the application range of the main cold compress patch band 1 is not enough to cover the swollen range, at this time, the external sub cold compress patch bands 2 are needed to perform derivative cold compress on the area that the main cold compress patch band 1 cannot cover. And the sub cold compress patch bands 2 are attached to the skin through pressure-sensitive adhesive, so that the derived sub cold compress patch bands 2 will closely attach to the skin. It should be noted that when applying the patch, the joint needs to be in a straight state, and then the main cold compress patch band 1 is applied on the straight joint. At this time, the main cold compress patch band 1 is attached to the straight swollen joint. In this way, when the joint moves, it squeezes the main cold compress patch band 1 and the sub cold compress patch bands 2, which is convenient for the main cold compress patch band 1 and the sub cold compress patch bands 2 to always closely attach to the swollen area and continuously perform cold compress during the subsequent joint movement, and at the same time, it will not prevent the normal rotation of the joint.

[0035] Conventional cold compress patches are usually attached to joints. Due to the movement of the joints, the cold compress patch will be continuously squeezed, which will cause the hydrogel in the cold compress patch to be squeezed to the surrounding areas by the joints. As the joints return to their original positions, the hydrogel that was originally inside the cold compress patch will not return to its original position. Therefore, as the joints continue to move, the hydrogel originally located inside the cold compress patch will be continuously pushed and squeezed to spread to the surrounding areas, but the pushed hydrogel will not return to its original position, so there will be depressions at the place where the cold compress patch is closely attached to the joint, and thus the effect of continuous cold compress cannot be achieved.

[0036] To address this phenomenon, this application document adopts a method for the return of the hydrogel to reset the originally squeezed hydrogel. That is, after the joint moves and squeezes the hydrogel and then the joint returns to its original position, the area on the cold compress patch that was sunken due to the joint squeezing will be refilled with the hydrogel that was pushed and moved away. Therefore, the cold gel can be re-applied to the joint, facilitating the re-cold compress on the swollen area of the joint.

[0037] Refer to Figure 3 and Figure 4 In the state, a plurality of first rubber partition plates 4 and a plurality of second rubber partition plates 5 are arranged linearly in the inner cavity. The plurality of first rubber partition plates 4 are arranged at the bottom of the inner cavity, and the plurality of second rubber partition plates 5 are arranged at the top of the inner cavity. Moreover, the plurality of first rubber partition plates 4 and the plurality of second rubber partition plates 5 are arranged in a staggered manner, that is, the first rubber partition plate 4 is located between two adjacent second rubber partition plates 5. When the joint moves, it will push against the first rubber partition plate 4 and move towards the second rubber partition plate 5, and at the same time, it will also drive the first rubber partition plate 4 to move and squeeze the hydrogel in the inner cavity to move, thereby transferring the originally heat-absorbing hydrogel.

[0038] It should be noted that the hydrogel that absorbs the heat of the swollen area will be temporarily stored in some areas of the main cold compress patch belt 1 and the auxiliary cold compress patch belt 2. The hydrogel in the heat-absorbing area that is closely attached to the moving joint part will transfer heat through flow, thereby cooling the heated hydrogel. Then, this part of the cooled hydrogel will reattach to the heated joint and continue to absorb heat.

[0039] Refer to Figure 3 and Figure 4 In the state, the inner cavity is divided into an upper cavity and a lower cavity. The lower cavity is attached to the human joint, so that the hydrogel in the lower cavity will be closely attached to the swollen joint and then absorb heat from the swollen and heated joint. The hydrogel in the upper cavity is for auxiliary material replacement, enabling the hydrogel in the upper cavity and the lower cavity to achieve material replacement and cooling.

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

[0041] Refer to 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 Figures 5-8 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 setting allows the hydrogel with a higher temperature originally in the lower cavity to mix with the hydrogel with a lower temperature in the upper cavity. That is, the hydrogel with a lower temperature in the upper cavity is squeezed by the side plate 7 and squeezed into the lower cavity from the extrusion silicone valve of the rubber-passing hole 9. Since both sides of the second rubber partition plate 5 have side plates 7 carrying the rubber-passing holes 9, both sides of the second rubber partition plate 5 enter the lower cavity below the second rubber partition plate 5 through the rubber-passing holes 9 under the squeezing action. During the squeezing process, 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 play a role in fully mixing and cooling the hydrogel with a higher temperature and the hydrogel with a lower temperature, cooling the hydrogel in the lower cavity close to the red and swollen area, and better cold compressing the red and swollen joint.

[0047] Among them, the first rubber partition plate 4, the second rubber partition plate 5, the side plate 7, and the connecting elastic membrane 8 are all heat-insulating materials, which avoid heat transfer caused by the indirect contact of the hydrogels in the upper cavity and the lower cavity, that is, realize the temperature isolation of the hydrogels in the upper cavity and the lower cavity, and allow the temperature exchange of the hydrogels in the upper cavity and the lower cavity to only complete the cooling of the hydrogel in the lower cavity during the process of squeezing into the lower cavity through the rubber-passing hole 9.

[0048] Furthermore, a plurality of water bags 6 are provided in the upper cavity, and the water bags 6 abut against the top of the first rubber partition plate 4. The water bags 6 are fixed to the top of the inner cavity. Refer to Figure 4 and Figure 9 the state shown, where the plurality of water bags 6 are independently arranged and fixed in the upper cavity located between two adjacent second rubber partition plates 5.

[0049] During the process of the joint bending and then stretching, the movement trend of the internal components in the inner cavity is as follows:

[0050] When the joint bends, since the water bag 6 abuts against the top of the first rubber partition plate 4, the first rubber partition plate 4 will push and squeeze the water bag 6, causing the water bag 6 to deform. The water bag 6 is a component with an outer elastic plastic bag and water filled inside. Therefore, at this time, the water bag 6 will form a change from Figure 6 to Figure 8 state.

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

[0052] Among them, multiple water bags 6 are arranged linearly. On one side of the main cold compress patch strip 1 and the auxiliary cold compress patch strip 2 close to the water bags 6, there are multiple heat conduction sheets for heat conduction. It should be noted that the setting of the water bags 6 can not only play a role in resetting the first rubber partition board 4, but also play a role in contacting and cooling the hydrogel re-squeezed into the upper cavity. That is, after the hydrogel squeezed into the upper cavity comes into contact with the water bags 6, heat conduction will occur, and the temperature of the hydrogel re-squeezed into the upper cavity will be conducted into the water bags 6, realizing the transfer of temperature and completing the cooling effect of the hydrogel in the upper cavity. At the same time, it prepares for cooling the hydrogel re-squeezed into the lower cavity. At the same time, the setting of the heat conduction sheets can timely export the heat of the hot water body in the water bags 6 through the heat conduction sheets, completing the cooling of the water bags 6.

[0053] It should be noted that a same curved elastic tube 10 is inserted through multiple second rubber partition boards 5. The setting of the curved elastic tube 10 can not only play a role in driving the main cold compress patch strip 1 to return to its original state and then driving the first rubber partition board 4 to reset after the joint is reset to be straight, but also because multiple flow holes are opened on the curved elastic tube 10, and the curved elastic tube 10 is used to connect the hydrogel between adjacent two second rubber partition boards 5. Such a setting can also be used to connect the internal space of the entire upper cavity. That is, when the hydrogel between two second rubber partition boards 5 in one area is squeezed and re-squeezed, it will also drive part of the hydrogel to exchange hydrogel substances through the multiple flow holes of the curved elastic tube 10. Therefore, it can better cool the hydrogel entering the upper cavity.

[0054] It should be noted that in the solution of this application, the use of multiple temperature conductions and the setting of multiple cooling areas can effectively improve the efficiency of cooling the red and swollen joints. The cooling process can realize the multiple transfers of the high-temperature hydrogel, contact with the water bags 6, and through the setting of connecting the upper cavity with multiple flow holes on the curved elastic tube 10, the heat-generating area of the joint swelling can be transferred to the corresponding upper cavity from the corresponding part of the lower cavity in contact. Then, through the extrusion and transfer of the hydrogel of the curved elastic tube 10, the hydrogel in the entire upper cavity becomes 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, improving the cooling efficiency. And the lower cavity composed of modular first rubber partition boards 4 can also ensure that the rotation of the joint is not affected.

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

[0056] When the elbow joint or knee joint of a patient is sprained and swollen, just apply the main cold compress patch 1 on the swollen area, and then tie or paste the adhesive strap 3 on the skin, so that the main cold compress patch 1 is fixed and closely attached to the swollen area. When the swollen area is large, only need to tear off two opposite auxiliary cold compress patches 2 when necessary, unfold the multiple auxiliary cold compress patches 2, and attach them to the swollen area through pressure-sensitive adhesive, so as to realize the cooling and cold compress of the swollen area;

[0057] When the joint moves, it will move towards the second rubber partition 5 against the first rubber partition 4, and at the same time, it will also drive the first rubber partition 4 to move and squeeze the hydrogel in the inner cavity to move, thereby transferring the hydrogel that originally absorbs heat, that is, the hydrogel in the lower cavity will closely adhere to the swollen joint and then absorb heat and reduce swelling of the swollen and hot joint;

[0058] During the extrusion process, the hydrogel with a lower temperature in the upper cavity will be squeezed into the lower cavity at a higher speed, so that the hydrogel with a lower temperature is quickly squeezed into the hydrogel with a higher temperature, which can play a role in fully mixing and cooling the hydrogel with a higher temperature and the hydrogel with a lower temperature, cool the hydrogel in the lower cavity close to the swollen area, and play a better role in cold compressing the swollen joint.

[0059] The hydrogel re-squeezed into the upper cavity is in contact for cooling, that is, when the hydrogel squeezed into the upper cavity contacts the water bag 6, heat conduction will occur, and the temperature of the hydrogel re-squeezed into the upper cavity will be conducted to the water bag 6, realizing the transfer of temperature and completing the effect of cooling the hydrogel in the upper cavity. At the same time, it is ready for cooling the hydrogel re-squeezed into the lower cavity. At the same time, the setting of the heat conduction sheet can timely export the heat of the heated water body in the water bag 6 through the heat conduction sheet, completing the cooling of the water bag 6.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
