[0002] More specifically, the invention relates to a next-generation smart healthcare convergence device, an active hot and cold temperature control smart multi-functional therapeutic splint and hot pack, which fundamentally overcomes the technical limitations of existing splints and hot packs and dramatically improves therapeutic effects, pain relief effects, user convenience, safety, and usability by integrating active hot and cold functions based on Peltier elements, a real-time temperature monitoring and ultra-precision control system for affected / painful areas based on multiple safety sensors, a user-customized treatment / hot pack protocol, intelligent remote control and data management functions through smartphone connectivity, and ergonomic design and various wearing / use modes.

[0003] The present invention can create innovative technical and industrial value across a wide range of medical and healthcare industry sectors, including the home, orthopedics, rehabilitation medicine, sports medicine, home healthcare, pain clinics, physical therapy, wearable medical devices, the silver industry, the beauty industry, and the general healthcare supplies market.

[0004] In particular, the present invention provides a groundbreaking multi-functional smart healthcare convergence device that can be widely used not only for splinting purposes for treatment such as fractures, sprains, and post-surgical rehabilitation, but also for pain relief and hot compresses in daily life, such as relieving stiff shoulders, back pain, menstrual cramps, muscle pain, and cold sensitivity. Background Technology

[0005] Splints are essential medical devices used to immobilize and stabilize the injured area during the treatment of conditions such as fractures or ligament injuries, playing a key role in supporting pain management and recovery.

[0006] Conventional splints firmly immobilize the fractured area to promote bone healing, but they do not include active cooling or heat therapy functions, causing patients the inconvenience and hassle of having to use separate cold or hot compress tools.

[0007] Cold compress therapy is highly effective in suppressing the initial inflammatory response and effectively reducing pain immediately after acute injury, while hot compress therapy is effective in aiding the recovery of the injured area by relieving chronic pain, promoting blood circulation, and inducing muscle relaxation.

[0008] Therefore, there has been a continuous clinical need for innovative medical devices capable of integrally providing these contrasting therapeutic effects in a single device.

[0009] Conventional hot and cold therapy methods require individual application using independent tools, which causes inconvenience for both patients and medical staff and requires a significant amount of time and effort, making it realistically difficult to provide effective integrated treatment.

[0010] The present invention aims to effectively solve the problems of the conventional technology described above by integrating cooling and heating functions into a single splint, thereby effectively alleviating acute and chronic pain in patients, promoting the reduction of inflammation, and ultimately dramatically increasing the speed of patient recovery.

[0011] In addition, the present invention is creatively designed to maximize patient convenience and treatment efficiency by adopting an ergonomic design that is easy to carry and use.

[0012] Smart splints equipped with such innovative integrated heating and cooling functions are expected to maximize treatment efficiency and improve patient satisfaction throughout various surgical treatments and rehabilitation processes, such as fractures, ligament tears, and muscle injuries.

[0017] Through this, it provides an innovative user environment that allows users to instantly switch between cooling and heating modes as desired, without the need for separate equipment or complex operation processes for hot and cold therapy, and

[0018] The goal is to maximize the complementary synergistic effects of hot and cold therapy to simultaneously provide complex therapeutic effects such as swelling relief, inflammation reduction, pain relief, improved blood circulation, muscle relaxation, and enhanced cell activity. This is an innovative technological challenge that fundamentally shifts the paradigm of existing splint technology and provides a customized temperature therapy solution optimized for patients.

[0019] Ultra-precision wound temperature control and stable maintenance based on multiple safety sensors: The present invention organically integrates a high-precision multiple safety sensor system (overheat sensor, low temperature sensor, skin contact sensor, humidity sensor, pressure sensor, motion sensor) capable of detecting even minute temperature changes in the wound in real time, and an artificial intelligence-based intelligent control algorithm (integration of PID control, fuzzy control, adaptive control, and predictive control algorithms).

[0020] In particular, the core objective is to control and stably maintain the temperature of the affected area within an ultra-precise error range of ±0.1℃. Through this, the goal is to accurately achieve the optimal treatment temperature to maximize therapeutic effects and to fundamentally prevent the risk of side effects that may occur due to temperature control failure, such as burns, low-temperature burns, skin irritation, and pressure ulcers.

[0021] This is a key technical challenge that fundamentally resolves the issues of temperature control precision and safety overlooked by existing technologies, and guarantees the highest level of safety and reliability for patients.

[0022] Provision of user-customized intelligent treatment protocols and advanced smart healthcare functions: The present invention provides an optimal customized treatment protocol that comprehensively considers the patient's disease type, severity of symptoms, treatment stage, and personal characteristics (age, gender, health status, skin sensitivity, etc.) through an on-device control panel and a smartphone app.

[0023] The core objective is to enable users to freely set all treatment parameters, such as treatment time, temperature, hot / cold mode, intensity, and intermittent operation, or to allow medical professionals to remotely set and manage patient-customized protocols.
