Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an acupoint patch heat preservation device. Background Technology

[0002] Acupoint patches, as an important carrier of traditional Chinese medicine external treatments, are highly sensitive to temperature conditions due to their transdermal absorption mechanism. In low-temperature winter environments, existing acupoint patches generally face technical bottlenecks such as plaster solidification and reduced migration rates of active ingredients. For example, when the ambient temperature is below 10℃, the oily components in the matrix are prone to phase transition and crystallization, leading to decreased permeability of the drug carrier; simultaneously, low temperatures inhibit Brownian motion of volatile components, resulting in a decrease in the diffusion coefficient of drug molecules.

[0003] To address this, in the prior art, Chinese patent application number CN212530596U discloses a winter-use acupoint patch heat-preserving device. This device includes a heat-preserving box, comprising a box body and a lid connected by a locking mechanism. Both the box body and lid have internal cavities, and heat-preserving cotton is fixed inside each cavity. A handle is fixed to the upper surface of the lid. Several partitions are vertically installed inside the box body, dividing the interior into several mounting cavities. A placement box is movably installed inside each mounting cavity, and a heating coil is installed inside each mounting cavity. Mounting holes are provided on both sides of the placement box, and heat-conducting copper blocks are installed inside each mounting hole. However, because this device uses an electric heating coil for heating, the generated heat is dry, easily evaporating the moisture from the acupoint patch. This not only accelerates the evaporation of free water on the surface of the patch but also disrupts the stable association structure of bound water and active ingredients within the medicinal material, thus affecting the therapeutic effect to some extent. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heat preservation device for acupoint patches, which can ensure the stability of bound water and active ingredients inside the acupoint patch while heating the patch.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A heat-insulating device for acupoint patches includes a heat-conducting pipe, a heat-insulating sleeve, a hot water tank, and a water pump. The heat-conducting pipe is spirally wound to form a square groove-shaped structure for placing the acupoint patch. The heat-insulating sleeve is wrapped around the square groove-shaped heat-conducting pipe. The hot water tank is located below the heat-insulating sleeve and is used to store hot water. The water pump connects the hot water tank and the heat-conducting pipe and is used to pump the hot water in the storage tank into the heat-conducting pipe to form a circulating water path.

[0007] In some embodiments, the acupoint patch heat preservation device further includes a heating rod, a heating switch, and a battery. The heating rod is installed in a hot water pool to heat the water in the pool. The battery is located outside the hot water pool to provide operating voltage. The heating switch is located on the wire between the heating rod and the battery.

[0008] In at least one embodiment, the acupoint patch heat preservation device further includes a start button, the water pump is an electric water pump, the electric water pump is electrically connected to the battery through a wire, and the start button is located on the wire between the electric water pump and the battery.

[0009] In at least one embodiment, the acupoint patch heat preservation device further includes a temperature sensor, a microcontroller, a display screen, and a temperature adjustment knob. The input end of the temperature sensor is installed in the hot water pool, and the output end is connected to the microcontroller. The display screen is connected to the microcontroller and is used to display the real-time temperature of the hot water in the hot water pool. The temperature adjustment knob is connected to the microcontroller and is used to control the temperature.

[0010] Compared with existing technologies, this invention achieves at least the following beneficial effects: This invention replaces the traditional electric heating coil with a hot water circulating heat-conducting pipe, utilizing the gentle heating properties of water to evenly transfer heat to the acupoint patch. Simultaneously, the trace amounts of water vapor generated during circulation maintain the humidity of the heating environment, effectively preventing excessive evaporation of the ointment's moisture and ensuring the stable release of the active ingredients of the medicinal materials. Furthermore, the indirect hot water heating method avoids the destruction of the bound water of the medicinal materials by localized high temperatures, maintaining the stable combination of moisture and active ingredients within the ointment, preventing hardening of the polymer matrix or agglomeration of components due to dryness, thereby improving the transdermal absorption efficiency of the drug. In addition, the spirally wound heat-conducting pipe design increases the heat exchange area, and the insulation sleeve reduces heat loss, concentrating heat energy on the acupoint patch, reducing the impact of external environmental temperature fluctuations, and significantly improving the overall energy efficiency of the heating system.

[0018] like Figures 1 to 3 As shown, the acupoint patch heat preservation device of this utility model includes a heat-conducting pipe 1, a heat-insulating sleeve 2, a hot water tank 3, a water pump 4, a heating rod 5, a heating switch 6, and a battery 7. The heat-conducting pipe 1 is spirally wound to form a square groove-shaped structure for placing the acupoint patch. The heat-insulating sleeve 2 wraps around the square groove-shaped heat-conducting pipe 1. The hot water tank 3 is located below the heat-insulating sleeve 2 and is used to store hot water. The water pump 4 connects the hot water tank 3 and the heat-conducting pipe 1, and is used to pump the hot water in the tank into the heat-conducting pipe 1 to form a circulating water path. The heating rod 5 is installed inside the hot water tank 3 and is used to heat the water in the hot water tank 3. The battery 7 is located outside the hot water tank 3 and is used to provide operating voltage. The heating switch 6 is located on the wire between the heating rod 5 and the battery 7.

[0019] The heat pipe 1 is a spiral copper pipe, which increases the heat exchange area and improves heat transfer efficiency. The insulation jacket 2 is a square cylindrical structure made of insulation material. In this embodiment, the insulation material is a closed-cell rubber-plastic insulation material. The closed-cell structure prevents water vapor penetration and maintains stable internal humidity.

[0020] refer to Figure 2Specifically, the acupoint patch heat preservation device also includes a start button 8. The water pump 4 is an electric water pump, which is electrically connected to the battery 7 via a wire. The start button 8 is located on the wire between the electric water pump and the battery 7. This design allows for quick disconnection of the electric water pump power supply in emergencies, preventing damage from dry running.

[0021] refer to Figure 2 Specifically, the acupoint patch heat preservation device also includes a temperature sensor 9, a microcontroller 10, a display screen 11, and a temperature adjustment knob 12. The input end of the temperature sensor 9 is installed in the hot water pool 3, and the output end is connected to the microcontroller 10. The display screen 11 is connected to the microcontroller 10 and is used to display the real-time temperature of the hot water in the hot water pool 3. The temperature adjustment knob 12 is connected to the microcontroller 10 and is used to control the temperature.

[0022] The temperature sensor 9 can detect the water temperature in real time and feed the data back to the microcontroller 10. The temperature control knob 12 can set the target temperature and input its signal to the microcontroller 10.

[0023] The acupoint patch heat preservation device also includes a housing 13, which comprises an upper housing 131, a lower housing 132, and a cover 133 that fits over the upper housing 131. The upper housing 131 is fixedly connected to the lower housing 132, and the cover 133 is hinged to the upper housing 131. Multiple arrays of heat-conducting pipes 1 and heat-insulating sleeves 2 are arranged within the upper housing 131, and connecting pipes 14 connect the arrays of heat-conducting pipes 1 in series. A hot water tank 3, a battery 7, a microcontroller 10, and a water pump 4 are all located within the lower housing 132. A display screen 11, a heating switch 6, a start button 8, and a temperature control knob 12 are all located on the front surface of the lower housing 132. By using multiple arrays of heat-conducting pipes 1 and heat-insulating sleeves 2, more acupoint patches can be heated simultaneously, meeting the needs of large-scale use.

[0024] In this embodiment, the temperature control knob 12 is a rotary encoder. Rotating the temperature control knob 12 will change its output pulse signal. At this time, the knob converts the mechanical rotation action into an electrical signal, which is input to the microcontroller 10. After receiving the knob signal, the microcontroller 10 parses it into a specific temperature value and stores it as the control target. The temperature sensor 9 monitors the water temperature of the hot water tank 3 in real time and feeds back the current temperature value to the microcontroller 10. The microcontroller 10 has a built-in safety threshold (such as a maximum of 45°C). If the feedback temperature exceeds the limit, it will immediately and automatically cut off the power supply to the heating rod 5 or manually cut off the power supply to the heating rod 5 through the heating switch 6.

[0025] In addition, to facilitate carrying by medical personnel, a handle 15 is provided on the top of the cover 133, and a spring lock is provided on one side of the cover 133 symmetrical to the hinge side to secure the cover 133 to the upper box 131. The spring lock makes it easy to lock the upper box 131 and the cover 133 securely when carrying.

[0026] The method of using the acupoint patch heat preservation device is as follows: When using, ensure that the hot water pool 3 of the lower box 132 is filled with clean water, and place the acupoint patch vertically in the square groove formed by the heat conduction pipe 1. If multiple acupoint patches need to be heated at the same time, place them in the grooves of the heat conduction pipe 1 in the upper box 131 respectively; press the start button 8 to start the electric water pump, so that the hot water circulates through the heat conduction pipe 1; press the heating switch 6 on the front surface of the lower box 132 to start the heating rod 5 to heat the water in the hot water pool 3; observe the real-time water temperature on the display screen 11. The microcontroller 10 has a set temperature. When the temperature sensor 9 feeds back to the microcontroller 10 that the temperature has reached the set value, the microcontroller 10 will automatically control the power of the heating rod 5 to keep the hot water at a constant temperature. If the temperature exceeds the set range, the heating rod 5 can be turned off immediately through the heating switch 6; if the heating intensity needs to be adjusted, the target temperature can be finely adjusted through the temperature adjustment knob 12.

[0027] It should be understood that all the above embodiments are exemplary and not restrictive.
