Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a structure for regulating body surface temperature. Background Technology

[0002] Cold and hot compresses on the human body surface are widely used in clinical practice and rehabilitation. For example, they are used to cool the head, prevent cerebral edema, reduce brain cell metabolism, and decrease its oxygen demand; cooling the body surface at the extraction site after tooth extraction can constrict blood vessels, reduce inflammation, and alleviate pain; cold compresses are also used after facial surgeries, including cosmetic procedures, to reduce inflammation; and cold compress therapy is a common treatment method after orthopedic surgery, as local cold compresses can constrict blood vessels and reduce traumatic pain and postoperative swelling.

[0003] Cryotherapy is low-cost, simple to operate, reusable, and has few side effects, making it suitable for patients with drug allergies. It is now widely used in various fields of medicine. In sports medicine, cryotherapy is often used preventatively in athletes during acute pain episodes to reduce muscle damage, alleviate muscle soreness, and accelerate recovery. In certain surgical procedures, cryotherapy can aid patient recovery. Post-spinal surgery cryotherapy can lower pain scores, reduce opioid use, and accelerate recovery due to its effects in reducing edema, inflammation, and muscle spasms. While cryotherapy for abdominal surgical incisions does not shorten hospital stays, it effectively relieves incision pain and reduces the need for analgesics.

[0004] Hot compress therapy plays an important role in the treatment of soft tissue injuries. It dilates blood vessels, improves local blood circulation, and promotes local metabolism, all of which are beneficial for recovery. Hot compresses themselves can also relieve muscle spasms and promote the absorption of inflammation and blood stasis. Medicated hot compresses allow the medication to be absorbed locally, directly reaching the affected area, making the treatment more direct and effective. Traditional Chinese medicine hot compress therapy combines the dual effects of medication and heat, resulting in significant therapeutic effects and is a commonly used thermotherapy method in clinical practice.

[0005] Whether using cold or hot compresses, various problems arise in practice. A prominent issue is the inconsistent temperature, often too high or too low, causing damage to the skin or tissues. Frequent changes to temperature-regulating devices such as water bags or towels result in short-lived periods of suitable temperature, failing to achieve satisfactory temperature regulation. Utility Model Content

[0006] To address the aforementioned problems, this utility model discloses a structure for regulating body surface temperature, thereby solving the problem that existing technologies using towels or water bags for body surface temperature regulation have short durations and fail to achieve satisfactory temperature regulation effects.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0026] like Figure 1 and 2 As shown, this utility model discloses a structure for regulating body surface temperature, including a temperature regulating part 1, a fixing band 2, and a power supply 4 (the power supply 4 is a DC power supply); the temperature regulating part 1 includes a temperature regulating layer, a temperature transmission layer 13, and a protective layer 14. The temperature regulating layer includes a Peltier semiconductor layer 11 and an insulating and heat-conducting layer 12 located on the upper and lower surfaces of the Peltier semiconductor layer 11; the upper and lower surfaces of the temperature regulating layer are provided with temperature transmission layers 13, and the outer surface of each temperature transmission layer 13 is provided with a protective layer 14; the power supply 4 is located on one side edge of the temperature regulating part 1 and is electrically connected to the Peltier semiconductor layer 11. The two ends of the temperature regulating part 1 are connected to fixing bands 2, and the two fixing bands 2 are detachably connected together. The power supply 4 is connected to a switch (not shown in the figure).

[0027] The aforementioned Peltier semiconductor layer 11 includes a plurality of Peltier semiconductor wafers spaced apart. All Peltier semiconductor wafers are connected in series, with the end wafers connected to the power supply 4 from the side. The heating or cooling surfaces of all Peltier semiconductor wafers are in the same direction. The working principle of the Peltier semiconductor wafers is that when N-type and P-type semiconductor elements are connected to form a thermocouple and a direct current is applied, one end of the thermocouple absorbs heat (cooling) and the other end releases heat (heating). Cooling or heating is determined by adjusting the direction of the current in the semiconductor. In this embodiment, a switch connected to the power supply 4 can control the output of forward or reverse current to achieve heating or cooling. As the forward or reverse current of the power supply 4 switches, the heating surface can be changed to a cooling surface, or vice versa.

[0028] Temperature probes 5 are installed in both of the above-mentioned temperature transfer layers 13 to collect temperature data within the temperature transfer layers 13, thereby enabling real-time monitoring of the temperature within the temperature transfer layers 13 and uploading the temperature data to the terminal via Bluetooth connection. Both temperature probes 5 are located near the power supply 4 and electrically connected to the power supply 4 to be powered by the power supply 4.

[0029] The aforementioned switch can be used in a general manner, manually switching on and off based on temperature data, or it can be designed as a temperature-controlled (thermal) switch, automatically connecting and disconnecting based on the temperature setting.

[0030] Specifically, the above-mentioned insulating and heat-conducting layer 12 is made of flexible material, and the thickness of the insulating and heat-conducting layer 12 is 0.01mm-10mm; the thickness of the above-mentioned temperature regulating layer is 1mm-50mm; for example, the size of the temperature regulating layer is 1.6mm (length) * 1.6mm (width) * 0.9mm (height).

[0031] In this embodiment, the insulating and thermally conductive layer 12 can be a 0.1mm flexible boron nitride film or a polyimide film, etc. Since boron nitride and polyimide have excellent thermal conductivity, electrical insulation and thermal stability, as well as flexibility, they can be used as a temperature transfer layer to uniformly conduct cold / heat energy from the contact surface to a large surface area, and then use large-area temperature difference convection and temperature radiation to exchange heat.

[0032] In this embodiment, the insulating and thermally conductive layer 12 and the Peltier semiconductor layer 11 are connected together by epoxy resin bonding or mechanical fixation.

[0033] In this embodiment, the temperature transfer layer 13 includes an insulating sealed cavity and a liquid filling the insulating sealed cavity. The cavity material is a water-resistant, comfortable, insulating, and thermally conductive material, such as PVC, PP, PU, ​​PE, TPU, etc., and the wall thickness of the insulating sealed cavity is 0.01mm-50mm. The thickness of the temperature transfer layer 13 is 0.1mm-50mm, preferably 0.2mm-20mm, and more preferably 0.3mm-15mm. The liquid can be used to store heat and transfer heat, and can be a mixture of water, saline solution, or absorbent polymer.

[0034] Specifically, the temperature transfer layer 13 and the insulating and heat-conducting layer 12 are bonded together with adhesive. The adhesive is a UV adhesive, or they can be bonded together by heating. The protective layer 14 and the temperature transfer layer 13 are bonded together with adhesive.

[0035] In the embodiments of this utility model, the protective layer 14 is a non-woven fabric, which can increase the comfort of the skin while protecting the temperature transmission layer 13; the fixing strap 2 is made of elastic non-woven fabric, etc., and a breathable Velcro 3 is provided at the end for easy fixation on the body; that is, the two fixing straps 2 are connected together by Velcro 3.

[0036] The aforementioned power supply 4 is equipped with a charging port, allowing for continuous battery life using an external power source or a portable power bank.

[0037] Application scenarios: This structure can be used for temperature regulation of the cheek area after tooth extraction, temperature regulation after cosmetic surgery, and other postoperative care of the head and face; it can also be used for knee or waist support for temperature care; it can also be used for orthopedic care and care of different parts of the human body surface; trunk temperature regulation, etc., with a wide range of applications.

[0038] Those skilled in the art should understand that variations can be implemented by combining existing technology with the above embodiments, which will not be elaborated here. Such variations do not affect the substantive content of this utility model, and will not be elaborated here.
