Description

Technical Field

[0001] This utility model relates to the field of ultrasonic physiotherapy technology, specifically to an ultrasonic physiotherapy electrode with a sustained-release layer. Background Technology

[0002] Ultrasonic pulsed electroconduction therapy is a novel dosage form and pharmaceutical method that uses physical force to propel drugs through intact skin into the body's circulation and diseased tissues to exert their therapeutic effects. This medical technology achieves targeted drug delivery and precise administration, offering many advantages over oral and injectable methods. The ultrasonic electroconduction device transmits pulsed force to metal electrode pads via its built-in ultrasonic treatment head, causing the drug in the foam to be emitted through the skin and enter the body. The device generates a microcurrent between the metal electrode pads and the body, promoting drug absorption through the skin surface. (Existing technology: Authorization Publication No. CN 219595618) U's patent discloses a coupling electrode patch for ultrasonic drug delivery, comprising a non-woven fabric layer, a double-sided adhesive layer adhered to the bottom of the non-woven fabric layer, an annular shell embedded in the middle of the non-woven fabric layer, the top of the annular shell connected to an electrode sheet shell via a connecting shell, a cotton mesh layer fixedly connected to the bottom of the annular shell, an aluminum foil layer embedded in the middle of the connecting shell, a sealing layer and an absorbent cotton layer fixedly connected to the bottom of the connecting shell, a first annular groove and a second annular groove formed on the top of the annular shell, a metal electrode sheet fixedly mounted at the bottom center of the electrode sheet shell, and a sealing layer and an absorbent cotton layer disposed between the connecting shell and the annular shell. The device ensures that the medication will not leak out during physiotherapy by using a sealing layer and a washable cotton layer, thus avoiding any impact on the surrounding non-woven fabric layer and electrode pads. The metal electrode pads are reusable, and the sliding block drives the positioning block to slide in the positioning groove, thereby achieving a fixed connection between the connecting shell and the electrode pad shell. However, the device lacks a sliding locking component for the positioning block in the positioning groove, which can easily lead to loose connections and leaves room for improvement. In addition, the device requires manual replenishment of the ultrasonic physiotherapy medication during use, which is cumbersome. Therefore, we propose an ultrasonic physiotherapy electrode pad with a sustained-release layer. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an ultrasonic therapy electrode pad with a sustained-release layer. The device achieves the installation and locking of the ultrasonic electrode pad through magnetic rotation and locking, and the ultrasonic electrode pad has good installation stability. At the same time, the sustained-release layer of the device is made of medical silicone soaked in medicine, which eliminates the need for manual filling of ultrasonic therapy medicine by staff. It is convenient to use and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic therapy electrode pad with a sustained-release layer, comprising a backing layer, a copper foil sheet at the bottom of the central circular hole of the backing layer, a microporous film on the lower side of the copper foil sheet, a drug sustained-release layer on the lower side of the microporous film, and a connecting mechanism.

[0005] Connection mechanism: It includes an arc-shaped connecting seat one, an arc-shaped slot, an arc-shaped connecting seat two, and an arc-shaped magnet strip. The arc-shaped connecting seat one is set in the central circular hole of the backing layer. The arc-shaped magnet strip is rotatably inserted into the arc-shaped slot opened on the inner arc surface of the arc-shaped connecting seat one. The right end of the arc-shaped magnet strip is provided with the arc-shaped connecting seat two. The inner arc surface of the arc-shaped connecting seat two is provided with an ultrasonic electrode plate. The device achieves the installation and locking of the ultrasonic electrode plate through magnetic rotation snap-fit. The installation stability of the ultrasonic electrode plate is good. At the same time, the sustained-release layer of the device is made of medical silicone layer soaked in drug solution, which eliminates the need for manual filling of ultrasonic therapy drug solution by the staff and makes it convenient to use.

[0006] Furthermore, the backing layer is a medical-grade polyurethane film layer, which improves the breathability of the ultrasonic therapy electrode pad with the sustained-release layer after wearing.

[0007] Furthermore, an adhesive layer is provided on the lower outer edge of the microporous membrane to bond the ultrasonic therapy electrode pad with the sustained-release layer to the patient's skin therapy area.

[0008] Furthermore, the adhesive layer is a low-allergenic medical acrylic pressure-sensitive adhesive layer, which improves the skin adhesion effect of the device through reasonable material selection.

[0009] Furthermore, a separator layer is provided between the adhesive layer and the drug sustained-release layer. The separator layer is a neoprene coating to prevent the ultrasonic therapy drug solution from penetrating into the adhesive layer.

[0010] Furthermore, a PET film is adhered to the underside of the adhesive layer to prevent external dust from entering the adhesive layer inside the ultrasonic therapy electrode pad with the sustained-release layer.

[0011] Furthermore, the connecting mechanism also includes an arc-shaped iron strip, which is disposed inside the arc-shaped slot. The arc-shaped iron strip is installed in conjunction with the arc-shaped magnet strip, and the arc-shaped magnet strip inserted into the ultrasonic therapy electrode pad with the slow-release layer is moved and locked by magnetic adsorption.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This ultrasonic therapy electrode pad with a sustained-release layer has the following advantages:

[0013] 1. When using ultrasonic therapy electrode pads with a sustained-release layer, the installation and locking of the ultrasonic electrode pads are achieved by using the magnetic rotation locking limit through the arc-shaped connecting seat one, arc-shaped slot, arc-shaped iron strip, arc-shaped connecting seat two, and arc-shaped magnet strip, thus achieving good installation stability of the ultrasonic electrode pads.

[0014] 2. When using ultrasonic therapy electrode pads with a sustained-release layer, the sustained-release layer is made of medical-grade silicone soaked in medication, eliminating the need for manual filling of the ultrasonic therapy medication by staff, making it convenient to use.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This embodiment provides a technical solution: an ultrasonic therapy electrode pad with a sustained-release layer, comprising a backing layer 1, a copper foil 2 at the bottom of a central circular hole in the backing layer 1, a microporous film 3 on the lower side of the copper foil 2, a drug sustained-release layer 4 on the lower side of the microporous film 3, the drug sustained-release layer 4 being made of medical-grade silicone soaked in a drug solution, the backing layer 1 being a medical-grade polyurethane film layer, an adhesive layer 6 on the lower outer edge of the microporous film 3, the adhesive layer 6 being a low-allergenic medical-grade acrylic pressure-sensitive adhesive layer, and a separator layer 5 between the adhesive layer 6 and the drug sustained-release layer 4, the separator layer 5 being a neoprene rubber coating. A PET film 7 is adhered to the underside of the adhesive layer 6. After peeling off the PET film 7, its smooth surface allows the ultrasonic therapy electrode pad with the sustained-release layer to be attached to the underside of the adhesive layer 6 before use, preventing dust and other impurities from entering the adhesive layer 6 and affecting the subsequent adhesion and wearing of the device. The ultrasonic therapy electrode pad with the sustained-release layer is then adhered to the skin surface of the area where the patient will receive ultrasonic therapy. The adhesive layer 6 uses a low-allergenic medical-grade acrylic pressure-sensitive adhesive layer, possessing excellent oxidation resistance, oil resistance, and solvent resistance, exhibiting good adhesion to various materials. With high brightness and high peel strength, it can withstand the effects of impact and vibration. During use, the input end of the ultrasonic electrode pad 8 is connected to the output end of an external ultrasonic transdermal drug delivery device. The ultrasonic waves from the ultrasonic electrode pad 8 act on the copper foil 2, passing through the microporous membrane 3 and the drug sustained-release layer 4 to reach the patient's skin surface. Simultaneously, the medication soaked in the medical silicone layer gradually penetrates into the patient's skin through contact. Through the synergistic effect of ultrasonic electrotherapy and drug therapy, physical therapy is provided to the patient. The separating layer 5 is a neoprene rubber coating. Neoprene rubber has good physical and mechanical properties, is oil-resistant, and resistant to... It is heat-resistant, flame-retardant, sunlight-resistant, ozone-resistant, acid and alkali-resistant, and chemical reagent-resistant, thus preventing the drug solution in the drug release layer 4 from penetrating into the adhesive layer 6 and reducing the adhesion effect of the adhesive layer 6. The microporous membrane 3 prevents the drug solution in the drug release layer 4 from penetrating into the copper foil 2 during the use of the device, preventing cross-interference, while allowing ions to pass through to transfer current. The backing layer 1 is made of medical-grade polyurethane film layer, which has good waterproof and breathable effect. The release layer of the device is made of medical silicone layer soaked with drug solution, which does not require manual filling of ultrasonic physiotherapy drug solution by the staff, making it convenient to use. It also includes a connecting mechanism 9.

[0021] Connection mechanism 9 includes an arc-shaped connecting seat 1 91, an arc-shaped slot 92, an arc-shaped connecting seat 2 94, and an arc-shaped magnet strip 95. The arc-shaped connecting seat 1 91 is disposed in the central circular hole of the backing layer 1. The arc-shaped magnet strip 95 is rotatably inserted into the arc-shaped slot 92 opened on the inner arc surface of the arc-shaped connecting seat 1 91. The right end of the arc-shaped magnet strip 95 is provided with the arc-shaped connecting seat 2 94. The inner arc surface of the arc-shaped connecting seat 2 94 is provided with an ultrasonic electrode plate 8. The connection mechanism 9 also includes an arc-shaped iron strip 93, which is disposed inside the arc-shaped slot 92. The arc-shaped iron strip 93 and the arc-shaped magnet strip 95 are installed together. When using an ultrasonic therapy electrode plate with a sustained-release layer, the ultrasonic electrode plate 8 is vertically inserted along the inner wall of the central circular hole of the backing layer 1 through the outer arc surface of the arc-shaped connecting seat 2 94. As the arc-shaped connecting seat 2 94 slides down until it is horizontally aligned with the arc-shaped connecting seat 1 91, the arc-shaped connecting seat 2 94 is rotated to allow the arc-shaped magnet strip 95 to rotate and insert into the arc-shaped slot 92. Through the rotational sliding engagement between the arc-shaped magnet strip 95 and the arc-shaped slot 92, the ultrasonic electrode plate 8 is vertically limited. Subsequently, through the magnetic attraction between the arc-shaped magnet strip 95 and the arc-shaped iron strip 93, the arc-shaped magnet strip 95 does not move after being rotated into the arc-shaped slot 92, thus achieving rapid installation of the ultrasonic electrode plate 8. The ultrasonic electrode plate 8 can be used multiple times, and the installation operation is convenient. The device achieves locking of the ultrasonic electrode plate 8 through magnetic rotation engagement, resulting in good installation stability of the ultrasonic electrode plate 8.

[0022] The working principle of the ultrasonic therapy electrode pad with a sustained-release layer provided by this utility model is as follows: When using the ultrasonic therapy electrode pad with a sustained-release layer, the ultrasonic electrode pad 8 is vertically slid down along the inner wall of the central circular hole of the backing layer 1 through the outer arc surface of the arc-shaped connecting seat 2 94. When the arc-shaped connecting seat 2 94 slides down to be horizontally aligned with the arc-shaped connecting seat 1 91, the arc-shaped connecting seat 2 94 is rotated to allow the arc-shaped magnet strip 95 to be inserted into the arc-shaped slot 92. Through the rotational sliding engagement between the arc-shaped magnet strip 95 and the arc-shaped slot 92, the ultrasonic electrode pad 8 is vertically limited. Subsequently, the arc-shaped magnet strip 95... The magnetic attraction between the body and the arc-shaped iron strip 93 ensures that the arc-shaped magnet strip 95, once inserted into the arc-shaped slot 92, does not shift position, thus enabling rapid installation of the ultrasonic electrode pad 8. The ultrasonic electrode pad 8 is reusable and easy to install. Then, the PET film 7 is peeled off. The smooth surface of the PET film 7 allows the ultrasonic therapy electrode pad with the sustained-release layer to be adhered to the underside of the adhesive layer 6 before use, preventing dust and other impurities from entering the adhesive layer 6 and affecting the subsequent adhesion and wearing of the device. The ultrasonic therapy electrode pad with the sustained-release layer is then adhered to the patient where treatment is needed. On the skin surface of the ultrasound therapy area, the adhesive layer 6 uses a low-allergenic medical-grade acrylic pressure-sensitive adhesive layer, which has excellent oxidation resistance, oil resistance, and solvent resistance. It exhibits good adhesion to various materials, high transparency, high peel strength, and can withstand the effects of impact and vibration. In use, the input end of the ultrasonic electrode pad 8 is connected to the output end of an external ultrasonic transdermal drug delivery device. The ultrasonic waves from the ultrasonic electrode pad 8 act on the copper foil 2, and pass through the microporous membrane 3 and the drug sustained-release layer 4 to act on the patient's skin surface. At the same time, the soaked drug solution in the medical silicone layer gradually penetrates into the skin through contact with the patient's skin. The device provides physiotherapy to patients through the synergistic effect of ultrasound electrotherapy and drug therapy within the patient's skin. The separating layer 5 is coated with neoprene rubber, which has good physical and mechanical properties, including oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. This prevents the drug solution in the drug-releasing layer 4 from penetrating into the adhesive layer 6, thus reducing the adhesive effect of the adhesive layer 6. The microporous membrane 3 prevents the drug solution in the drug-releasing layer 4 from penetrating into the copper foil 2 during device use, preventing cross-interference, while allowing ions to pass through to transmit current. The backing layer 1 is made of medical-grade polyurethane film, which has good waterproof and breathable properties.
