Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an electroporation patch and an integrated portable visual transdermal drug delivery device. Background Technology

[0002] Transdermal drug delivery technology refers to a non-invasive treatment method that uses physical means (such as electric current) to promote drug penetration through the skin and directly reach the lesion site under the guidance of electrode pads. It is widely used in pain management, anti-inflammation, and local drug delivery. The electric field generated by the current produces a directional driving force for drug ions, allowing the active ingredients in the drug to penetrate the skin and mucous membranes more deeply and effectively and quickly enter the human body, targeting the lesion and related acupoints. Its core technology stems from a deep understanding of biological tissues and pharmacokinetics. Through transdermal drug delivery equipment and consumables, it gently acts on the human skin and mucous membranes, temporarily changing the permeability of cell membranes. At the same time, the mid-frequency electric field can also promote blood circulation and lymphatic return, achieving the effect of physical therapy and massage.

[0003] Existing electroporation equipment mainly includes ultrasonic transdermal drug delivery devices and electrical stimulators. Their general structure consists of a main unit, wires, and electrode pads (physiotherapy consumables). The electrode pads are mostly connected by cables, which makes the connection operation cumbersome and the wiring messy.

[0004] In addition, the internal components of existing transdermal drug delivery devices are scattered, resulting in a large size and heavy weight, which makes it inconvenient for users to carry at home and use when going out, thus limiting the application scenarios of transdermal drug delivery therapy.

[0005] Therefore, there is a market demand for a portable electroporation patch with a small main unit, electrode patches that can adapt to different body parts, and an integrated portable visual transdermal drug delivery device. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an electroporation medicated patch.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an electroporative patch, including a patch body, and further including a plurality of drug-permeable parts disposed on the patch body, and a magnetic snap connection end disposed on the patch body for communicating with a drug-permeable device. The magnetic snap connection end consists of a plurality of conductive contacts, and the plurality of conductive contacts can contact and align with the magnetic snap interface of the drug-permeable device.

[0008] In some embodiments, the transdermal patch body is a non-woven fabric layer.

[0009] In some embodiments, the transdermal patch body has two circular electrode areas in the middle, each circular electrode area including a conductive layer and a drug-carrying layer, and four conductive contacts located between the two circular electrode areas.

[0010] In some embodiments, it also includes wing-shaped fixing parts disposed on both sides of the transdermal patch body, which can attach the transdermal patch body to the human body.

[0011] Another technical problem to be solved by the present invention is to provide an integrated portable visual drug delivery device.

[0012] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an integrated portable visual transdermal drug delivery device, including the electro-transdermal patch and the transdermal main unit as described in any of the above embodiments. The transdermal main unit includes a main unit shell, a display screen, a control motherboard, a battery and a magnetic snap interface integrated in the main unit shell from top to bottom.

[0013] In some embodiments, the transdermal drug delivery system further includes a partition disposed within the housing of the system for separating and fixing the control motherboard and the battery, with the control motherboard disposed above the partition and the battery disposed below the partition.

[0014] In some embodiments, the main unit housing includes a top main unit housing, a middle main unit housing, and a bottom main unit housing. The partition is disposed between the top main unit housing and the middle main unit housing. The battery is fixed to the lower surface of the partition and located inside the middle main unit housing. The control motherboard is fixed to the upper surface of the partition and located inside the top main unit housing.

[0015] In some embodiments, a magnetic snap mounting hole is provided at the bottom of the lower shell of the main unit, the magnetic snap interface is installed in the magnetic snap mounting hole, the magnetic suction surface of the magnetic snap interface is provided outward through the magnetic snap mounting hole, and the magnetic snap interface can be connected to the magnetic snap connection end of the electroporation patch through the magnetic snap mounting hole.

[0016] In some embodiments, two electrode through holes are also provided at the bottom of the lower shell of the main unit, and the positive and negative output terminals of the battery are respectively connected to the electrode area on the electroporation patch through the electrode through holes for conductive contact.

[0017] In some embodiments, the control board has an adhesion detection circuit. When the electro-permeable patch adheres to the skin and forms a conductive circuit, the control board detects the circuit continuity signal, determines that the adhesion is normal, and allows the treatment output to be started. When the electro-permeable patch does not adhere to the skin, the circuit is open and the operation cannot be started.

[0018] The scope of this invention is not limited to technical solutions formed by specific combinations of the above-described technical features, but also includes other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.

[0019] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art: The present invention provides an electro-permeable patch and an integrated portable visual transdermal drug delivery device. The electro-permeable patch, by setting multiple transdermal sections, can achieve simultaneous transdermal drug delivery treatment to multiple sites. The multiple conductive contacts of the magnetic snap connection end are aligned and connected with the magnetic snap interface of the transdermal drug delivery device. The connection method is convenient, and the contact conductivity is stable and reliable. It can be applied to transdermal drug delivery treatment to multiple parts of the whole body, meeting the needs of multiple scenarios such as home and travel. The transdermal drug delivery host adopts an internal structure in which the display screen, control motherboard, battery and magnetic snap interface are integrated from top to bottom. This achieves a high degree of integration and lightweighting of the host, greatly reducing the size of the host and making it easy to carry and use. At the same time, the integrated display screen can intuitively display treatment parameters and status information, making operation simpler and clearer, effectively reducing the user's usage threshold and improving the convenience and safety of the treatment process.

[0020] Meanwhile, the mid-frequency electric field output by the device can promote local blood circulation and lymphatic return, and has the effect of physical therapy and massage, realizing the integration of transdermal drug delivery and physical therapy, and meeting various clinical needs such as pain management, anti-inflammation, and local drug delivery.

[0022] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of the present invention will be described in detail below.

[0023] This embodiment describes an electroporation patch and an integrated portable visual transdermal transdermal device, including a transdermal transdermal host 1 and an electroporation patch.

[0024] like Figure 3 As shown, the transdermal patch body 2 is made of non-woven fabric, which is easy to bend and can be adapted to the curved contours of different parts of the human body.

[0025] The transdermal patch body 2 is provided with two circular transdermal portions 202. Each transdermal portion 202 includes a conductive layer and a drug-carrying layer, which are used to carry the drug liquid and conduct the therapeutic current.

[0026] A magnetic snap connection end 201 is provided between the two drug-penetrating sections 202, and the magnetic snap connection end 201 has four conductive contacts.

[0027] The two sides of the transdermal patch body 2 extend to form wing-shaped fixing parts 203, which are used to firmly stick the transdermal patch body 2 to the surface of human skin.

[0028] The electro-permeable patch features a magnetic snap connection, making it easy to insert and remove, lightweight, and durable. Existing transdermal drug delivery devices often use universally designed square or round electrode patches. When used on joints such as the knee, elbow, shoulder, and ankle, the complex joint surfaces and frequent movements make it difficult for these universal electrode patches to adhere properly, leading to gaps, uneven current density, and a stinging sensation. The edges are also prone to lifting, affecting efficacy and user experience. Furthermore, the inability to completely cover the target treatment area results in limited stimulation and poor therapeutic effects. This embodiment addresses this issue by using an ergonomically designed electro-permeable patch, no longer a simple rectangle or circle, but tailored to the specific anatomical contours of the joint. Made of non-woven fabric, its flexible nature ensures that the patch remains tightly adhered to the skin during joint flexion and extension movements, without shifting or lifting edges.

[0029] like Figure 1-2 As shown, the outer shell 11 of the transdermal drug delivery unit 1 is composed of an upper shell 111, a middle shell 112, and a lower shell 113 assembled sequentially.

[0030] The main unit casing 11 integrates, from top to bottom, a display screen 103, a control motherboard 101, a partition 102, a battery 104, and a magnetic snap interface 105. Its highly integrated and miniaturized design utilizes a highly integrated microcontroller and miniaturized circuit modules, resulting in a suitable size for easy handholding and pocket carrying. Powered by a rechargeable lithium battery, the transdermal patch body 2 is connected to the magnetic snap interface 105 during application.

[0031] The partition 102 is installed between the upper shell 111 and the middle shell 112 of the main unit. The control motherboard 101 is fixed on the upper surface of the partition 102 and located inside the upper shell 111 of the main unit. The battery 104 is fixed on the lower surface of the partition 102 and located inside the middle shell 112 of the main unit. The partition 102 separates and fixes the control motherboard 101 and the battery 104, optimizing the internal space layout.

[0032] The display screen 103, control buttons, and Type-C charging port are all soldered onto the control motherboard 101. The display surface of the display screen 103 faces the top opening of the main unit's upper shell 111. The display screen 103 is a color LCD screen integrated into the front of the transdermal drug delivery device, providing a visual interactive interface. This screen is used to display important information such as graphical parameter settings, dynamic treatment display, treatment plan selection and guidance, and connection status indication. Existing transdermal drug delivery devices mostly use knobs or simple digital tube displays, and parameter settings rely on manuals or experience. Users (especially home users) find it difficult to intuitively understand information such as the current mode, intensity, and remaining time, which can easily lead to operational errors or poor efficacy. The visual LCD screen greatly reduces the barrier to use, making the treatment process transparent and standardized, improving treatment compliance and safety. The automatic screen saver power-saving mode effectively extends the device's battery life and further enhances the convenience of use when out and about.

[0033] like Figure 2 As shown, the control button operation surface is exposed through the button hole on the top of the main unit's upper shell 111, and the Type-C charging port interface end is exposed through the charging port hole on the side of the main unit's outer shell 11, making it convenient for users to operate and charge.

[0034] The bottom of the main unit's lower casing 113 has a magnetic snap mounting hole 107 and two electrode through holes 106. The magnetic snap interface 105 is installed in the magnetic snap mounting hole 107, and its magnetic surface protrudes outward through the magnetic snap mounting hole 107, so that it can be magnetically aligned and connected with the magnetic snap connection end 201 of the electro-permeable patch. The positive and negative output terminals of the battery 104 respectively make contact with the two transdermal parts 202 through the two electrode through holes 106 to achieve wireless connection, which is suitable for use in multiple scenarios such as home and travel.

[0035] The control motherboard 101 integrates an adhesion detection circuit, which is used to detect the adhesion status between the electroporation patch and the skin.

[0036] The working principle and usage process of this device are as follows: During use, first, evenly apply the medication to the drug-carrying layer of the two transdermal patches 202. Align the magnetic snap connection end 201 of the transdermal patch with the magnetic snap interface 105 of the transdermal host 1. A quick connection is achieved through magnetic attraction, with the four conductive contacts corresponding to the magnetic snap interface 105 to ensure stable conductivity. Then, peel off the protective film on the back of the transdermal patch and smoothly attach it to the treatment area using the wing-shaped fixing parts 203 on both sides. At this time, the adhesion detection circuit automatically detects whether the transdermal patch and skin form a complete conductive circuit. If the patch is not properly adhered, resulting in an open circuit, the transdermal host 1 cannot start the treatment output; the system is only allowed to start when the patch is properly adhered and forms a circuit. A light press of the right-side plus button on the control motherboard 101 illuminates the display screen 103. A long press of the plus button switches treatment modes, and a short press adjusts the treatment level. After the system starts, it enters the treatment process. The treatment duration can be preset on the display screen. After the set duration is reached, the system automatically stops the current output to avoid overtreatment. During treatment, the display screen 103 shows the power level, duration, mode, battery level, and alarm information in real time. If the system is not used for an extended period, the display screen 103 automatically enters a power-saving screen saver mode, which can be woken up by pressing any button. After treatment, the system automatically stops outputting; simply disconnect the magnetic clasp and remove the electro-optic patch.

[0037] The electro-permeable patch uses non-woven fabric with wing-shaped fixing parts to fit closely to the complex curves of joints such as the knee, elbow, shoulder, and ankle. It is not easy to shift or lift during movement, ensuring a uniform and stable current field, reducing skin irritation, and improving drug penetration efficiency. The magnetic snap connection replaces the traditional cable connection, making it easy to plug and unplug and eliminating the problem of messy wiring. At the same time, the medium-frequency electric field output by the device can promote local blood circulation and lymphatic return, and also has a physiotherapy and massage effect, realizing the integration of transdermal drug delivery and physical therapy.

[0038] The transdermal drug delivery unit adopts an internal layered integrated layout, with partitions separating and fixing components, achieving high integration and lightweight design, significantly reducing size and weight, making it easy to hold or carry in a pocket for treatment anytime, anywhere. The integrated display screen intuitively shows various parameters and statuses, making operation simple and easy to understand, lowering the barrier to entry for home users. The adhesion detection circuit effectively avoids accidental activation due to improper adhesion, improving treatment safety and compliance. It retains the essence of traditional electrodialysis while offering intuitive operation, significantly reducing the size of the main unit and improving portability. The irregularly shaped transdermal patches can adapt to different body parts, providing more comprehensive stimulation coverage, realizing a multi-purpose transdermal drug delivery physiotherapy device.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
