Description

Technical Field

[0001] This invention relates to the technical field of thermotherapy patches, specifically a visual thermotherapy patch. Background Technology

[0002] With advancements in technology and medical expertise, new medical technologies are constantly emerging, among which thermotherapy has garnered increasing attention. Heat therapy has enormous potential in areas such as pain relief, swelling reduction, and rehabilitation. Traditional thermotherapy methods primarily involve attaching small squares containing resistance wires to the affected area with adhesive tape, connected to an electrical wire to generate heat. However, because the heated area is not visible, problems such as overheating, redness, swelling, and allergies may go undetected, potentially causing secondary damage.

[0003] Currently, hyperthermia, especially in the rehabilitation treatment of fractures or muscle atrophy surgeries, is often achieved by heating a device containing a circular plastic block with an internal resistance wire. This type of heating device has a small heating area, the heated area is not visible, and it is difficult to directly observe changes on the skin surface in the heated area, making it difficult to observe adverse reactions. Patients typically have several modules applied simultaneously during treatment, each requiring a separate heating wire, which is inconvenient for patient movement and can easily create safety hazards.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 6This invention provides a technical solution: a visual thermotherapy patch, comprising a flexible PET substrate 1 and a control box 15 for multiple heating films. A flexible transparent heating film 2 is disposed on the flexible PET substrate 1. The flexible transparent heating film 2 is composed of a metal mesh structure. An antistatic film 3 is disposed on the top of the flexible transparent heating film 2. The antistatic film 3 is a microporous film material made of polytetrafluoroethylene plastic. A heat insulation layer 4 is disposed between the flexible transparent heating film 2 and the antistatic film 3. The heat insulation layer 4 is a heat-insulating transparent paper with ventilation holes 5. The flexible transparent heating film 2 is made of flexible material and can fit well with the patient's lesion area. The user can clearly see the skin in the lesion area and stop treatment in time when problems are found.

[0025] A protective film layer 6 is provided on the heat insulation layer 4. The vent 5 extends to the outside through the heat insulation layer 4 and the protective film layer 6. A connecting airbag 7 is bonded between the protective film layer 6 and the flexible PET substrate 1. The setting of the connecting airbag 7 is conducive to the transition between the thickness of the protective film layer 6 and the flexible PET substrate 1, so that the skin fit is better and the user experience is improved.

[0026] The flexible PET substrate 1 has double-sided adhesive layers 8 on both sides and top. Release paper 81 is adhered to the double-sided adhesive layers 8. A pull paper 82 protrudes from one side of the release paper 81. The pull paper 82 and the release paper 81 are integrally formed. The release paper 81 protects the double-sided adhesive layers 8 before use. When using, simply pinch the pull paper 82 with your fingers to separate the release paper 81 from the double-sided adhesive layers 8, which makes it easy for the double-sided adhesive layers 8 to adhere to the user's skin. This is beneficial to the stability of the adhesion and is convenient to operate.

[0027] A small lithium battery 9 is installed inside the flexible PET substrate 1. The small lithium battery 9 is electrically connected to the flexible transparent heating film 2. A preset temperature and time button 10 is installed at the bottom of the flexible PET substrate 1. Pressing the preset temperature and time button 10 sets the appropriate heating temperature and heating time. A USB connection interface 11 is opened on the outside of the small lithium battery 9 on the flexible PET substrate 1. A connector plug 12 is plugged into the USB connection interface 11. One end of the connector plug 12 is connected to the controller line 13. The entire system has an overheat detection device and a temperature sensor, which can effectively prevent overheating.

[0028] The other end of the controller cable 14 is connected to a heating film power supply connector 14. A heating film power supply interface 16 is provided on one side of the multi-heating film combined control box 15. Multiple heating film power supply interfaces 16 are provided and arranged along the side of the multi-heating film combined control box 15. The heating film power supply connector 14 is plugged into the heating film power supply interface 16. An LCD display screen 17 is provided on the multi-heating film combined control box 15. A control button 18 is provided on one side of the LCD display screen 17 on the multi-heating film combined control box 15. During use, a heating film can be used alone, and the preset heating temperature and heating time can be selected. Alternatively, multiple heating films can be applied at the same time, and then controlled uniformly by the multi-heating film combined control box 15, selecting the required heating temperature and heating time.

[0029] A rigid mounting shell 91 is fixed on a flexible PET substrate 1. The rigid mounting shell 91 is provided with an adjustable abutment limiting component. The abutment limiting component is a miniature structure and includes a movable plug 92. A receiving groove 93 is provided on the top of the USB connection interface 11 on the rigid mounting shell 91. The movable plug 92 is slidably inserted into the receiving groove 93. An elastic element 94 is fixedly connected between the movable plug 92 and the receiving groove 93. The elastic element 94 can be a small spring or a sheet. An elastic blocking structure is formed between the elastic element 94 and the movable plug 92 to protect the USB connection interface 11 when not in use.

[0030] A sliding groove 95 is provided on the front side of the receiving groove 93 on the rigid mounting housing 91. A pulling block 96 is fixed on the front side of the movable plug 92 on the sliding groove 95. A latching groove 97 is provided on the front side of the pulling block 96. The height of the movable plug 92 is greater than the height of the USB connection interface 11. A limiting groove 98 is provided at the upper edge of the connector 12. The bottom of the movable plug 92 matches the limiting groove 98. By holding the latching groove 97 with a finger and pulling the pulling block 96 upward, the bottom of the movable plug 92 is accommodated in the receiving groove 93. Then, the connector 12 is plugged into the USB connection interface 11. The pulling block 96 is released. Under the elastic force of the elastic element 94, the bottom of the movable plug 92 is inserted into the limiting groove 98, which is beneficial to the stability of the connection between the connector and the USB connection interface.

[0031] In summary, this invention aims to design a portable, visualized thermotherapy patch. The entire system consists of three parts: a flexible, transparent heating film 2, a control box 15 for multiple heating films, and a power supply. The flexible, transparent heating film 2 is made of flexible material, allowing it to fit well with the patient's lesion area. The user can clearly see the skin in the lesion area and stop treatment promptly if problems are detected. The control system allows for setting appropriate heating temperatures and times. It can be charged using a small lithium battery 9 or powered by the control power supply. This simple and straightforward approach is suitable for any patient and provides a good user experience.
