[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Example 1:

[0030] like Figures 1-3 In the illustrated embodiment, the base 104 is used to mount various functional components. The base 104 can be manufactured by injection molding, and its material can be polypropylene, polyethylene, ABS resin, etc.

[0031] The silicone layer 112, located at the bottom of the base 104, comes into contact with the skin during use, keeping the cavity of the base 104 relatively sealed to prevent the active ingredients of the medication from escaping. To ensure a better fit between the silicone layer 112 and the skin, the silicone layer 112 has a hollow structure. The silicone layer 112 is bonded to the bottom of the base 104. A strap 105 located at the base 104 securely fixes the base 104 to the affected area, preventing it from detaching during use.

[0032] The medicine storage section is used to store the medicinal liquid. Specifically, the medicine storage section includes a medicine liquid storage tank 107, which is used to store the extracted traditional Chinese medicine liquid. The medicine liquid storage tank 107 is connected to the interior of the cavity via a guide pipe 103. In use, the medicine liquid is sent into the cavity through the guide pipe 103, and the medicine inlet valve is used to control the opening and closing of the guide pipe 103. One optional connection method between the medicine liquid storage tank 107 and the base 104 is that a slot 102 is provided at the base 104, and the medicine liquid storage tank 107 is secured to the base 104 via the slot 102.

[0033] The medication application section is used to administer medication to the affected area of ​​the patient. Specifically, the medication application section includes absorbent cotton 108, which is suspended inside the cavity. When the traditional Chinese medicine liquid flows out from the guide tube 103, it is absorbed by the absorbent cotton 108, thereby preventing the effective ingredients of the traditional Chinese medicine liquid from contacting the skin and causing skin irritation.

[0034] The absorbent cotton 108 can be made of sodium polyacrylate resin. When the sodium carboxylate groups on the molecular chain of sodium polyacrylate come into contact with water, the sodium carboxylate groups ionize, producing carboxylate ions and sodium ions. The carboxylate ions carry a negative charge and will electrostatically attract hydrogen atoms in water molecules, forming hydrogen bonds. Because there are numerous carboxylate ions on the polymer chain, they can interact with water molecules. However, the effective components of traditional Chinese medicine liquids are organic compounds and do not have specific adsorption sites for binding with sodium polyacrylate resin. Therefore, sodium polyacrylate resin ensures the absorption of the traditional Chinese medicine liquid without affecting the volatilization of the effective components.

[0035] In use, the base 104 is fixed to the affected area by the straps 105. At regular intervals (after the herbal liquid at the absorbent cotton 108 has evaporated), the herbal liquid is introduced into the absorbent cotton 108 through the inlet valve at the guide tube 103. The herbal liquid absorbed by the absorbent cotton 108 evaporates, allowing the active ingredients to reach the affected area. Simultaneously, the patient's body temperature raises the temperature inside the cavity of the base 104, thereby accelerating the evaporation of the active ingredients from the herbal liquid at the absorbent cotton 108.

[0036] Example 2:

[0037] Based on Example 1, in order to improve the accuracy of single-dose administration, such as Figure 1 In the illustrated embodiment, an optional form of a drug inlet valve is provided. The drug inlet valve includes a suction tank 101 and a push rod 106. The suction tank 101 is disposed on the outer wall of the drug storage tank 107. The end of the push rod 106 is slidably connected to a piston that cooperates with the inner wall of the suction tank 101. The inner cavity of the suction tank 101 intersects with the guide pipe 103. One-way valves are disposed on the guide pipe 103 and located on both sides of the suction tank 101, so that the drug liquid flows unidirectionally along the section of the guide pipe 103.

[0038] When the push rod 106 is pulled out, negative pressure is generated in the suction barrel 101, at this time, the one-way valve between the suction barrel 101 and the medicine liquid storage tank 107 is in an open state, the one-way valve between the suction barrel 101 and the base 104 is in a closed state, and the traditional Chinese medicine liquid stored in the medicine liquid storage tank 107 is sucked into the inner cavity of the suction barrel 101. When the push rod 106 is pushed in, positive pressure is generated in the suction barrel 101, at this time, the one-way valve between the suction barrel 101 and the medicine liquid storage tank 107 is in a closed state, the one-way valve between the suction barrel 101 and the base 104 is in an open state, and the traditional Chinese medicine liquid in the inner cavity of the suction barrel 101 is sent to the adsorbing cotton 108 at the base 104.

[0039] In order to further improve the accuracy of single administration, the suction barrel 101 can be transparent made of polypropylene material, and the outer wall of the suction barrel 101 is provided with a scale mark, so that the medicine amount can be observed.

[0040] Embodiment 3:

[0042] The inner wall of the base 104 is provided with a mounting seat 110, and one optional form of connection between the adsorbing cotton 108 and the base 104 is that the adsorbing cotton 108 is connected to the mounting seat 110 of the base 104 through the first frame 111 by a threaded connection. Another optional form is that the adsorbing cotton 108 is connected to the mounting seat 110 of the base 104 through the first frame 111 by a clamping connection.

[0043] Embodiment 4:

[0044] On the basis of any one of embodiments 1-3, in the embodiment shown in Figure 2 In order to prevent the traditional Chinese medicine liquid flowing out of the flow guide pipe 103 from flowing through the gap between the adsorbing cotton 108 and the base 104, causing the traditional Chinese medicine liquid to contact the skin of the patient's part, the end of the flow guide pipe 103 located in the cavity is in contact with the adsorbing cotton 108.
