Abstract
Description
Technical Field
[0001] This invention relates to a heat therapy device, or more precisely, a heat therapy patch. Background Technology
[0002] Existing heat therapy patches only use heat to enhance the absorption of drugs by the skin. In this way, the penetration of drugs into the skin is very limited and the effect is not good. For example, the prior art patent publication number: CN210962580U discloses a Chinese invention patent document for a modified local heat therapy patch, as shown in Figure 5. Although the technical solution disclosed in this patent document can add drugs during the heat therapy process, the penetration effect of drugs into the skin is poor. Summary of the Invention
[0003] The purpose of this invention is to provide a heat therapy patch that can simultaneously increase the internal pressure of the inner heat therapy cover and decrease the internal pressure of the annular groove by pushing the first piston inward and pulling the second piston outward. This creates a negative pressure in the annular groove, allowing the device to adhere to the skin and achieve a cupping effect. Furthermore, it increases the pressure of the medicinal liquid inside the inner heat therapy cover, allowing the medicinal liquid inside the inner heat therapy cover to penetrate the skin at a certain pressure after the main permeation membrane adheres tightly to the skin, thus improving the penetration effect of the medicinal liquid.
[0004] To achieve the above objectives, the present invention employs the following technical solution: A heat therapy patch includes a nested adsorption and penetration device, a linkage pushing device, and a linkage driving device. The nested adsorption and penetration device includes an outer heat therapy cover and an inner heat therapy cover. The inner heat therapy cover is installed inside the outer heat therapy cover. Both the inner and outer heat therapy covers are shell structures with openings at the bottom. An annular groove is provided between the outer and inner heat therapy covers. The bottom opening of the inner heat therapy cover is provided with a main permeation membrane. The linkage pushing device includes a column, a transmission rod, a first piston cylinder, and a second piston cylinder. The two ends of the transmission rod can cooperate with the first and second piston cylinders respectively. One side of the column is connected to the outer heat therapy cover, and the other side of the column is hinged to the transmission rod. The inner heat therapy cover is filled with a medicinal liquid.
[0005] To further achieve the objectives of this invention, the following technical solution can also be adopted: The first piston cylinder includes a first tube, a first piston is installed inside the first tube, the first piston can slide inside the first tube, the middle part of the first tube passes through the shell of the outer heat compress cover and the shell of the inner heat compress cover, the outer side of the first piston is in contact with the inner wall side of the first tube, one side of the first piston is connected to an extension plate, one side of the transmission rod is connected to a transmission column, the arc-shaped side of the transmission column can cooperate with the extension plate, and the other side of the transmission rod is connected to a pull rope. The second piston cylinder includes a second tube, the second tube passes through the shell of the outer heat compress cover, a second piston is installed inside the second tube, the outer side of the second piston is in contact with the inner wall side of the second tube, one end of the pull rope cooperates with the transmission rod, and the other end of the pull rope is connected to one side of the second piston. The length of the transmission rod between the column and the transmission column is H, and the length of the transmission rod between the column and the pull rope is G, where H is less than G. A one-way valve is installed at one end of the first tube, the inlet of the one-way valve is connected to one end of the first tube, and the diameter of the second tube is greater than the diameter of the first tube.
[0006] The linkage drive device includes a first handle and a second handle. The first handle is connected to one side of the transmission rod, and one side of the second handle is connected to the external heat compress cover.
[0007] The inner wall of the inner heat compress cover is connected to a heater, and a fixing rod is connected to one side of the inner heat compress cover. One end of the fixing rod is connected to the outer heat compress cover.
[0008] An annular silicone membrane is installed between the outer heat compress cover and the inner heat compress cover. The inner and outer sides of the annular silicone membrane are connected to the opening of the inner heat compress cover and the opening of the outer heat compress cover, respectively. The annular silicone membrane can seal the opening of the annular groove.
[0009] The opening end of the inner heat compress cover is connected to a fixing ring. The side circumference of the fixing ring is connected to the side circumference of the opening end of the inner heat compress cover. The middle hole of the fixing ring has an internal thread. A support plate is installed on the inner side of the fixing ring. The outer side circumference of the support plate has an external thread. The support plate is threadedly connected to the fixing ring. Several mesh holes are opened on the support plate. A pressure ring is installed inside the inner heat compress cover. The outer side circumference of the pressure ring is connected to the inner wall side circumference of the inner heat compress cover. A main permeation membrane is installed between the pressure ring and the support plate. The pressure ring and the support plate can cooperate to clamp the side circumference of the main permeation membrane. Several mesh holes are opened on the fixing ring.
[0010] The lower opening of the inner heat compress cover is connected to the main permeation membrane, and the side periphery of the main permeation membrane is connected to the side periphery of the lower opening of the inner heat compress cover. An elastic strap is installed on the outer heat compress cover.
[0011] The advantages of this invention are: This invention combines a nested adsorption-permeation device, a linked pushing device, and a linked driving device, enabling simultaneous achievement of: ① The linkage drive device allows personnel to easily rotate the transmission rod by gripping the first and second handles, thereby simultaneously pushing the first piston inward and pulling the second piston outward. This increases the internal pressure of the inner heat compress cover and decreases the internal pressure of the annular groove. On the one hand, it creates a negative pressure in the annular groove, allowing the device to adhere to the skin and achieve a cupping effect. On the other hand, it increases the pressure of the medicinal liquid inside the inner heat compress cover, allowing the medicinal liquid inside the inner heat compress cover to penetrate the skin at a certain pressure after the main permeation membrane adheres tightly to the skin, thus improving the penetration effect of the medicinal liquid.
[0012] ② Since the length of the transmission rod between the column and the transmission rod is H, and the length of the transmission rod between the column and the pulling rope is G, H is less than G, and the diameter of the second tube is greater than the diameter of the first tube, during the manual rotation of the transmission rod, the volume extracted by the second piston cylinder from the outer heat pack is greater than the volume injected into the inner heat pack by the first piston cylinder. This allows for a slight increase in the pressure of the medicine inside the inner heat pack while significantly reducing the pressure inside the annular groove. This ensures that the annular groove generates sufficient suction, allowing the device to fit more stably with the skin and preventing excessive pressure inside the inner heat pack from disrupting the negative pressure inside the annular groove. Furthermore, it prevents excessive pressure inside the inner heat pack, avoiding excessive medicine overflow and preventing the low-pressure environment inside the annular groove from being disrupted due to excessive liquid volume inside the inner heat pack.
[0013] ③ When the transmission rod of the linkage pushing device is driven to rotate, the one-way valve can prevent the medicine in the inner heat pack from returning to the inside of the first tube, thereby keeping the linkage pushing device in the state after the transmission rod has been rotated.
[0014] ④ This invention allows for convenient one-time operation by personnel, while simultaneously creating negative pressure within the annular groove to achieve a cupping effect on human skin and increasing the internal pressure of the inner heat compress cover, thereby allowing the medicinal liquid inside the inner heat compress cover to penetrate into human skin at a certain pressure.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:
[0018] A type of heat patch, such as Figures 1-4 As shown, the device includes a nested adsorption and permeation device, a linkage pushing device, and a linkage driving device. The nested adsorption and permeation device includes an outer heat compress cover 12 and an inner heat compress cover 14. The inner heat compress cover 14 is installed inside the outer heat compress cover 12. Both the inner heat compress cover 14 and the outer heat compress cover 12 are shell structures with openings at the bottom. An annular groove 24 is provided between the outer heat compress cover 12 and the inner heat compress cover 14. The bottom opening of the inner heat compress cover 14 is provided with a main permeation membrane 22. The linkage pushing device includes a column 8, a transmission rod 7, a first piston cylinder, and a second piston cylinder. The two ends of the transmission rod 7 can cooperate with the first piston cylinder and the second piston cylinder, respectively. One side of the column 8 is connected to the outer heat compress cover 12, and the other side of the column 8 is hinged to the transmission rod 7. The inner heat compress cover 14 is filled with a medicinal liquid.
[0019] This invention combines a nested adsorption-permeation device, a linked pushing device, and a linked driving device, enabling simultaneous achievement of: ① The linkage drive device allows personnel to easily rotate the transmission rod 7 by gripping the first handle 1 and the second handle 2, thereby simultaneously pushing the first piston 5 inward and pulling the second piston 11 outward. This increases the internal pressure of the inner heat compress cover 14 and decreases the internal pressure of the annular groove 24. On the one hand, it creates a negative pressure in the annular groove 24, allowing the device to adhere to the human skin and achieve a cupping effect. On the other hand, it increases the pressure of the medicinal liquid inside the inner heat compress cover 14, so that after the main permeation membrane 22 adheres tightly to the skin, the medicinal liquid inside the inner heat compress cover 14 can penetrate into the human skin at a certain pressure, improving the penetration effect of the medicinal liquid.
[0020] ② Since the length of the transmission rod 7 between the column 8 and the transmission column 3 is H, and the length of the transmission rod 7 between the column 8 and the pulling rope 9 is G, H is less than G, and the diameter of the second tube 10 is greater than the diameter of the first tube 6, during the manual rotation of the transmission rod 7, the volume extracted from the outer heat pack 12 by the second piston cylinder is greater than the volume injected into the inner heat pack 14 by the first piston cylinder. This allows for a slight increase in the pressure of the medicine inside the inner heat pack 14 while significantly reducing the pressure inside the annular groove 24. On the one hand, this allows the annular groove 24 to generate sufficient suction, enabling the device to fit more stably with the human skin and preventing excessive pressure inside the inner heat pack 14 from disrupting the negative pressure inside the annular groove 24. On the other hand, it prevents excessive pressure inside the inner heat pack 14, avoids excessive medicine overflow, and prevents the low-pressure environment inside the annular groove 24 from being disrupted due to excessive liquid inside the inner heat pack 14.
[0021] ③ When the transmission rod 7 of the linkage pushing device is driven to rotate, the one-way valve 20 can prevent the liquid medicine in the inner heat pack 14 from returning to the inside of the first tube 6, thereby keeping the linkage pushing device in the state after the transmission rod 7 has been rotated.
[0022] ④ This invention allows for convenient one-time operation by personnel, while simultaneously creating negative pressure within the annular groove 24 to achieve a cupping effect on human skin and increasing the internal pressure of the inner heat compress cover 14, thereby allowing the medicinal liquid inside the inner heat compress cover to penetrate into human skin at a certain pressure.
[0023] Specific material selection and feasibility analysis: The samples we actually manufactured used the accompanying drawings as blueprints, and were implemented according to the proportions and fit methods of each component in the drawings. The connections used were common methods such as strong adhesive bonding, welding, riveting, flange connections, and one-piece molding connections. In actual manufacturing, the corresponding connection method, thickness, and strength of the connection points can be selected according to the actual connection strength requirements without creative innovation. One side of the first piston 5 is connected to the extension plate 4, which increases the mating area between the transmission column 3 and the extension plate 4. One side of the outer heat pack 12 is connected to the fixing rod 13, and one end of the fixing rod 13 is connected to the inner heat pack 14. In actual operation, the operator can hold the first handle 1 and the second handle 2, push the openings of the outer heat compress 12 and the inner heat compress 14 to fit against the human skin with a certain pressure, and then manually push the first handle 1 and the second handle 2 together, thereby creating negative pressure in the annular groove 24 at the same time, achieving the cupping effect. At the same time, this suction force makes the main permeation membrane 22 fit tightly against the human skin, creating positive pressure inside the inner heat compress 14, thereby accelerating the penetration of the medicine inside the inner heat compress 14 into the human skin. Example 2:
[0024] A type of heat patch, such as Figures 1-4As shown, the device includes a nested adsorption and permeation device, a linkage pushing device, and a linkage driving device.

The length of the transmission rod 7 between the column 8 and the transmission column 3 is H, and the length of the transmission rod 7 between the column 8 and the pull rope 9 is G. H is less than G. One-way valve 20 is installed at one end of the first tube 6. The inlet of the one-way valve 20 is connected to one end of the first tube 6. The diameter of the second tube 10 is larger than the diameter of the first tube 6.
[0026] After the first tube 6 of the present invention passes through the shell of the outer heat compress cover 12 and the shell of the inner heat compress cover 14, the joint between the first tube 6 and the outer heat compress cover 12 is sealed and bonded with sealant.

[0028] A type of heat patch, such as Figures 1-4 As shown, the device includes a nested adsorption and permeation device, a linkage pushing device, and a linkage driving device. The nested adsorption and permeation device includes an outer heat compress cover 12 and an inner heat compress cover 14. The inner heat compress cover 14 is installed inside the outer heat compress cover 12. Both the inner heat compress cover 14 and the outer heat compress cover 12 are shell structures with openings at the bottom. An annular groove 24 is provided between the outer heat compress cover 12 and the inner heat compress cover 14. The bottom opening of the inner heat compress cover 14 is provided with a main permeation membrane 22. The linkage pushing device includes a column 8, a transmission rod 7, a first piston cylinder, and a second piston cylinder.

[0030] The linkage drive device of the present invention allows personnel to easily rotate the transmission rod 7 by gripping the first handle 1 and the second handle 2, thereby simultaneously pushing the first piston 5 inward and pulling the second piston 11 outward. This simultaneously increases the internal pressure of the inner heat compress cover 14 and decreases the internal pressure of the annular groove 24. On the one hand, this creates a negative pressure in the annular groove 24, allowing the device to adhere to the human skin. On the other hand, it increases the pressure of the medicinal liquid inside the inner heat compress cover 14, so that after the main permeation membrane 22 is in close contact with the skin, the medicinal liquid inside the inner heat compress cover 14 can penetrate into the human skin at a certain pressure, thus improving the penetration effect of the medicinal liquid.

[0035] An annular silicone membrane 15 is installed between the outer heat compress cover 12 and the inner heat compress cover 14. The inner and outer sides of the annular silicone membrane 15 are connected to the opening of the inner heat compress cover 14 and the opening of the outer heat compress cover 12, respectively. The annular silicone membrane 15 can seal the opening of the annular groove 24.
[0036] When a negative pressure is formed inside the annular groove 24, the part of the annular silicone membrane 15 that contacts the human skin can form an annular recessed area, thereby generating a certain adsorption force between the annular silicone membrane 15 and the human skin, so that the device can adhere to the human skin. Example 7:
[0037] A type of heat patch, such as Figures 1-4 As shown, the device includes a nested adsorption and permeation device, a linkage pushing device, and a linkage driving device. The nested adsorption and permeation device includes an outer heat compress cover 12 and an inner heat compress cover 14. The inner heat compress cover 14 is installed inside the outer heat compress cover 12. Both the inner heat compress cover 14 and the outer heat compress cover 12 are shell structures with openings at the bottom.
