Description

Technical Field

[0001] This utility model relates to the field of transdermal drug delivery instruments, and specifically to a transdermal drug delivery device for acupoints. Background Technology

[0002] Transdermal drug delivery refers to a novel technology that administers drugs through the skin surface, allowing the medication to pass through the skin at a constant (or near-constant) rate and enter the systemic circulation to produce systemic or local therapeutic effects. Traditional transdermal drug delivery to acupoints typically involves wiping the skin with a liquid preparation or applying a plaster. Because the skin is the primary barrier for drug entry into the body, studies have found that only a very small number of drugs using traditional methods have excellent skin permeability; most drugs do not easily penetrate the skin, resulting in slow absorption, low absorption rates, and inadequate therapeutic effects. For plaster treatments at acupoints, the application time generally needs to be several hours or more. Prolonged application slows drug absorption, and prolonged application to the skin surface can easily cause skin allergies in some people with allergies or during hot seasons. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a transdermal drug delivery device for acupoints. This device applies pressure to the suction cups to adhere to the skin at acupoints, and then heats the area with a heating pad, which accelerates the penetration of the drug into the skin barrier, promotes drug circulation and absorption, and enhances efficacy. Compared with the method of applying a pharmaceutical patch, it greatly shortens the drug delivery time, eliminates the pain of long-term application of medicated plasters, and is rechargeable for convenient portability and use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The control circuit board includes a digital display module, multi-function buttons, and a Type-C interface.

[0006] Furthermore, the top cover is provided with a display window, keycaps, and a charging port. The digital display module is configured to correspond to the display window, the multi-function buttons are configured to correspond to the keycaps, and the Type-C interface is configured to correspond to the charging port.

[0007] Furthermore, the outer ring of the bottom surface of the suction cup is provided with a vacuum adsorption groove, the inner ring of the bottom surface of the suction cup is provided with a vacuum adsorption groove and a drug storage groove, the vacuum adsorption groove is provided with a ventilation hole that runs through the top and bottom, the top of the suction cup is provided with a sensor placement groove, and the sensor assembly on the lower cover is correspondingly provided with the sensor placement groove.

[0008] Furthermore, the vacuum pump is equipped with an air suction tube at one end, and the other end of the air suction tube is connected to the vent hole on the suction cup.

[0009] Furthermore, the sensor assembly includes a temperature sensor and a pressure sensor, both of which are electrically connected to the control circuit board.

[0018] As shown in the figure: This utility model discloses a transdermal drug delivery device for acupoints, including an upper cover 1, a suction cup 2, a lower cover 3, and a control circuit board 4. The lower cover 3 is located below the upper cover 1, the suction cup 2 is located below the lower cover 3, and the control circuit board 4 is located inside the upper cover 1. A heating element 5 is installed inside the suction cup 2. The suction cup 2 is fixedly connected to the lower part of the lower cover 3 through a pressure ring 6. A vacuum pump 31, a battery 32, a solenoid valve 33, and a sensor assembly 34 are installed on the upper part of the lower cover 3. The control circuit board 4 is equipped with a digital display module 41, a multi-function button 42, and a Type-C interface 43.

[0019] The top cover 1 is equipped with a display window 11, keycaps 12, and a charging port 13. The digital display module 41 is correspondingly set to the display window 11, the multi-function button 42 is correspondingly set to the keycap 12, and the Type-C interface 43 is correspondingly set to the charging port 13. The information on the digital display module 41 can be displayed through the display window 11, which can be used to display the set temperature, time, and battery information. The multi-function button 42 can be used for powering on / off and function operation of the device. The Type-C interface 43 can be used to charge the device, and a universal Type-C charger can be used for charging, making it convenient to carry and use.

[0020] The suction cup 2 has a vacuum adsorption groove 21 on the outer ring of its bottom surface and a drug storage groove 22 on the inner ring of its bottom surface for placing preparations. The preparations are made of medical non-woven fabric impregnated with a drug solution. The vacuum adsorption groove 21 has a through-hole 20. The suction cup 2 has a sensor placement groove 23 on its top surface. The sensor assembly 34 on the bottom cover 3 is correspondingly arranged in the sensor placement groove 23.
