Utilizing a semiconductor cooling chip as a substrate, it provides selective dual-temperature therapy, changing the traditional methods of ice packs and physical cooling. Because semiconductors offer selectable size, light weight, and controllable temperature, combined with a controllable photon therapy circuit, it is suitable for cooling various wounds, relieving subcutaneous exudation, and alleviating pain, especially for those with subcutaneous exudation, swelling, pain, phlebitis, soft tissue inflammation and swelling, inflammation and swelling caused by punctures, and those using indwelling intravenous catheters. Its infrared radiation at the hot end and the photon therapy from the additional light source constitute a complete spectral treatment for wounds. It is powerful, simple, convenient, and easy to operate, overcoming many inconveniences of physical cooling with ice packs and the significant limitation of not being able to perform open photon therapy after wound dressing closure, thus opening a new chapter in the comprehensive functionality of bandages.

[0003] However, this multifunctional semiconductor cold compress and heat therapy anti-inflammatory and analgesic treatment bandage also has some problems. For example, when applying cold compress, the semiconductor generates heat, raising the temperature of the cold compress area and affecting the cold compress effect.

The support frame 12 can support the water tank 9 and ensure its stability. The water inlet pipe at the top of the water tank 9 is equipped with a sealing cap, which makes it easy to pour the coolant raw materials into the mixture.

[0034] The interior of the water tank 9 is filled with coolant, which, by mass percentage, consists of the following components: 50% modified ethylene glycol, 6% surface-modified nano-alumina, 2% modified phosphate corrosion inhibitor, 1% modified polyether surfactant, and the balance deionized water. The modified ethylene glycol is ethylene glycol modified with a silane coupling agent. The modification process is as follows: the silane coupling agent is added to ethylene glycol at 2% of the ethylene glycol mass, and the mixture is stirred and reacted at 90°C for 3 hours. After cooling, the mixture is obtained, which can improve the heat absorption effect.

[0035] The surface-modified nano-alumina is nano-alumina modified with stearic acid, with a particle size of 60 nm. The modification process is as follows: stearic acid is dissolved in ethanol at 4% of the mass of nano-alumina, nano-alumina is added and ultrasonically dispersed for 45 minutes, and then filtered and dried. The modified phosphate ester corrosion inhibitor is a quaternized modified alkyl phosphate ester. The modified material can improve the effect of the coolant.

[0036] Working principle: The module's temperature regulation relies on the Peltier effect of the semiconductor cooling chip 2, and the switching between cooling and heating modes is achieved through voltage polarity switching.

[0037] Cooling mode: A positive voltage is applied to the thermoelectric cooler 2, forming a cold end at its bottom and a hot end at its top. The heat is quickly conducted to the copper box 3 made of purple copper through the attached thermal grease. At this time, the power of the cooling water pump 5 is turned on, driving the coolant in the water tank 4 to flow into the copper box 3. After exchanging heat with the copper box 3, the coolant carrying heat is transported to the finned heat sink 6 through the water pipe. Through the large-area heat exchange of the fins and air convection, the heat is dissipated to the outside. The cooled coolant then flows back to the copper box 3, forming a closed-loop heat dissipation circuit, continuously removing the heat generated by the thermoelectric cooler 2 and maintaining the cooling effect.

[0038] Heating mode: Switch the voltage polarity of the semiconductor cooling chip 2, with its bottom becoming the hot end and its top becoming the cold end. At this time, the cooling water pump 5 can adjust its speed according to the actual temperature requirements. The coolant still flows along the closed-loop path to avoid the local temperature of the cold end being too low, which would affect the heating stability and ensure that the heat is released evenly.

[0039] The module achieves bidirectional adaptation between automatic and manual water replenishment through the three-way valve 7, ensuring a stable liquid volume in the closed-loop water circulation system.

[0040] Automatic water replenishment: When the liquid level in water tank 4 is lower than the preset threshold, water replenishment pump 8 starts, draws pre-mixed coolant from water replenishment tank 9, and injects it into water tank 4 through three-way valve 7 until the liquid level reaches the set standard. Then water replenishment pump 8 stops working, completing automatic liquid replenishment without manual intervention.

[0041] Manual water replenishment: When a small amount of coolant needs to be added during module operation, it can be injected directly through the conical funnel 10 and quickly flow into the water tank 4 through the corresponding channel of the three-way valve 7. There is no need to disassemble the equipment or interrupt operation, making the operation convenient.

[0042] The mixing mechanism inside the water tank 9 is used to achieve uniform mixing of the coolant, preventing component stratification from affecting heat conduction and antifreeze performance. Its power transmission and mixing process is as follows:

[0043] When the power supply to the electric actuator 14 is turned on (either an external power supply or a self-contained power supply), and controlled by a controller, the output end of the electric actuator 14 extends and retracts, causing the slide bar 15, which is bolted to it, to slide up and down along the transmission box 13. The slide bar 15 is slidably set with the transmission box 13 via a slide rail, guiding the slide bar 15. The roller 16 at the bottom of the slide bar 15 moves synchronously with the slide bar 15, and the roller 16 rolls in the sliding hole of the gear plate 17, driving the gear plate 17 to rotate around its own axis. The gear disc 17 is rotatably mounted on the transmission box 13 via bearings, ensuring the smooth rotation of the gear disc 17. The teeth of the gear disc 17 are conical, and the teeth of the gear disc 17 mesh with the small bevel gear 18, transmitting rotational power to the small bevel gear 18. The small bevel gear 18 is coaxially fixed with the main sprocket 19, thereby driving the main sprocket 19 to rotate synchronously. The main sprocket 19 can drive the chain 20 to rotate, and the chain 20 can drive the secondary sprocket 21 to rotate. The secondary sprocket 21 is keyed to the rotating rod 22. Next, the rotating rod 22 rotates accordingly. The rotating rod 22 is rotatably set with the transmission box 13 via bearings to ensure the smooth rotation of the rotating rod 22. The rotating rod 22 can drive the large gear 23 to rotate. The large gear 23 on the rotating rod 22 meshes with the small gear 24, thus driving the small gear 24 to rotate. The small gear 24 transmits power to the rotating drum 25. The rotating drum 25 is rotatably set with the water replenishment tank 9 via bearings to ensure the smooth rotation of the rotating drum 25. The rotating drum 25 drives the mixing rod 26 on its surface to rotate at high speed in the water replenishment tank 9, stirring the liquid in the tank and ensuring that the liquids of different components are mixed evenly. At the same time, the main sprocket 19 drives the coaxial rotating shaft 27 to rotate. The rotating shaft 27 is rotatably set with the rotating drum 25 via bearings to ensure the smooth rotation of the rotating shaft 27. The rotating shaft 27 is rotatably set with the water replenishment tank 9 via bearings to ensure the smooth rotation of the rotating shaft 27. The scraper frame 28 at the right end of the rotating shaft 27 rotates close to the inner wall of the water replenishment tank 9 to scrape off the liquid remaining on the tank wall.
