Description

Technical Field

[0001] This invention relates to the field of wearable cooling devices, and more particularly to a wearable temperature control device and method suitable for patients with fever. Background Technology

[0002] Currently, the number of patients with influenza-like and viral fever remains high. High temperatures can cause irreversible damage to human tissues, and medical treatment for fever generally falls into two categories: medication and physical cooling methods. This device primarily targets physical cooling methods, such as wiping with hot towels, applying ice packs, and using fever-reducing patches. However, these traditional heat dissipation methods are passive, require frequent replacement, are labor-intensive, and inconvenient to use.

[0003] When using traditional methods to lower body temperature, patients often experience difficulties in temperature control, resulting in either excessive cooling or overheating, insufficient duration of cooling, and significant fluctuations in body temperature.

The wearable body 2 includes a flexible, fitted protective sheet 200. Bandages 3 are provided on the upper and lower sides of the flexible, fitted protective sheet 200 and along its extension direction. A flow channel 4 is provided inside the flexible, fitted protective sheet 200.

Then close the first control valve 20a and the second control valve 21a. Then connect the first delivery pipe 41 to the first adapter 20 and the second delivery pipe 42 to the second adapter 21, forming a coolant flow channel 4 within the flexible adhesive sheet 200 through the first delivery pipe 41, the semiconductor cooling heater 7, the circulating pump 6, and the second delivery pipe 42. The device is connected to a power source via USB interface 11. Display screen 8 shows the parameters of the temperature control device. The semiconductor cooling and heating unit 7 provides cooling, delivering coolant to the flexible protective sheet 200 for cooling the feverish patient. Temperature sensor 5 embedded in the surface of the flexible protective sheet 200 simultaneously monitors the temperature of the coolant and the feverish patient. This allows for real-time adjustment of the coolant flow rate in the circulating pump (6) and the operating power of the semiconductor cooling and heating unit (7), thereby regulating the coolant temperature within the flexible protective sheet 200 and improving its comfort.

[0018] In this invention, the flexible bonding sheet 200 is prepared from the following materials: 80-100 parts of PDMS, 8-12 parts of reinforcing agent, 6-10 parts of catalyst, 5-12 parts of curing regulator, 10-18 parts of crosslinking agent, and 8-15 parts of diluent; the PDMS is hydroxyl-terminated polydimethylsiloxane or vinyl-terminated polydimethylsiloxane, the reinforcing agent is fumed silica, and the catalyst is a platinum-divinyltetramethyldisiloxane complex; the curing regulator is 1-ethynyl-1-cyclohexanol or 3,5-dimethyl-1-hexyn-3-ol, and the crosslinking agent is polymethylhydrosiloxane. The diluent is low-viscosity polydimethylsiloxane, which has extremely low viscosity and high fluidity, as well as good dielectric properties and arc resistance. It can eliminate and suppress foam and facilitate demolding. The catalyst can control the curing speed of PDMS, and fumed silica can improve the toughness and mechanical strength of PDMS. During mixing, under the action of the catalyst, Si-Vi (vinyl) in the mixture reacts with Si-H in the crosslinking agent to form a three-dimensional network structure, allowing PDMS to flow from the liquid... The body is transformed into an elastic solid; in this invention, the preparation process of the flexible adhesive patch 200 includes the following steps: PDMS, reinforcing agent, catalyst, curing regulator, and then crosslinking agent and diluent are added in sequence and stirred evenly to obtain PDMS prepolymer liquid; the PDMS prepolymer liquid is divided into two equal parts, two master plates with flow channels 4 are selected, a temperature sensor 5 is placed on one of the master plates, the two parts of PDMS prepolymer liquid are poured onto the corresponding master plates respectively, the PDMS prepolymer liquid on the master plates is scraped flat so that it completely covers the flow channel structure on the master plates, and then placed under sealed conditions and dried with hot air at 40-60℃ to form a PDMS thin patch, after demolding the PDMS thin patch on the master plate, the two PDMS thin patches are aligned and bonded, and connectors are set on the inlet and outlet of the flow channel structure, and then the edges of the two PDMS thin patches are hot-pressed together to form the flexible adhesive patch 200, and finally bandages 3 are bonded or sewn on the edges of the flexible adhesive patch 200 to form the wearable body 2. The PDMS thin patch combines biomimetic principles and utilizes biocompatible materials such as PDMS to create a flexible, microchannel-based adhesive patch 200. Optimizing the patch's shape, size, and curvature allows for better adhesion to the skin's micro and macro structures, significantly improving heat transfer, comfort, and breathability. It can move flexibly with the patient, providing real-time personalized temperature thermal management and health monitoring, thereby enhancing the patch's precision and preventing discomfort. The flexible adhesive patch 200 utilizes coolant added to the microchannels 4, circulating and cooling it using a semiconductor cooling heater. A temperature sensor 5 is installed on the flexible adhesive patch 200, and the coolant flow and temperature are intelligently controlled via the semiconductor cooling heater 7 and circulating water pump 6.Placing the flexible protective patch 200 near the earlobe on the side can cool the neck of a feverish patient, avoiding the use of cold towels and ice packs and reducing the difficulty of operation. The temperature sensor on the flexible protective patch 200 can detect temperature changes on the patch in real time. By sensing the temperature near the earlobe, the body temperature can be determined. The combination of these two factors can adjust the flow and temperature of the coolant to maintain the comfort of the patient and adjust it to a suitable temperature in a timely manner. The bandage 3 can be removed and reapplied for continued use.

[0019] This invention also provides a wearable temperature control method suitable for patients with fever, the wearable temperature control method comprising the following steps: First, the wearer is set into three age groups by controlling the control box 1, and the physical cooling range of the wearing body 2 is set according to the wearer's age group, for example, the physical cooling range is set to 35.5-38.5. The temperature sensor 5 on the wearing body 2 collects the wearer's heat temperature, and the controller adjusts the basic operating power of the semiconductor cooling heater 7 according to the collected heat temperature. Second, the basic operating power of the semiconductor cooling heater 7 is dynamically corrected for different age groups according to the collected heat temperature, and the power correction result corresponding to the heat temperature of different age groups is obtained. The adjusted output power is then executed. In this invention, the basic operating power of the semiconductor cooling heater (7) is dynamically corrected for different age groups according to the collected heat temperature, including the following steps: Step 11: Introduce the Lightweight Gradient Boosting Model (lightGBM) into the controller. Based on the wearer's collected thermal temperature, divide the data into age groups and use the resulting feature dynamic weighting vectors as input to the LightGBM gradient boosting model. , The raw feature data mainly includes the following data: rebound temperature T 反弹 (Maximum temperature rebound after cooling), the range of purely physical cooling (T), and the rate of temperature change (calculated based on a 10-minute sliding window), and the cumulative cooling time. t 累计 (Starting from device startup and data collection, age group 7-16 only: record the maximum temperature difference between the previous lowest temperature and the subsequent temperature rise), where the body temperature change rate satisfies: ; as well as P 上一时刻 Power value (records the power value during the previous PWM output of the controller); Step 12: Predict base power according to different age groups, and the corresponding output base power is: P 基础A， base power P 基础A satisfy: ; A Age-stratified coding; where, A 0 = 7-16 years old, 1 = 17-55 years old, 2 = 55 years old and above; Combined with expert annotations for optimal power P 专家A With base power P 基础A Minimize the error δ between the predicted power and the expert-annotated optimal power. The sum of the absolute errors between the predicted power and the expert-annotated power (the closer to the expert-annotated power, the smaller this error δ) satisfies: ; Where λ is the regularization coefficient, and when A=0 and A=2, λ=0.1; when A=1, λ=0.05; and Ω is the model complexity penalty term (complexity measure). For the first i The predicted power of each sample The "optimal power" labeled by experts (i.e., the reasonable power recognized in clinical practice, and the power manually labeled during training); Based on age stratification, dynamic weights are assigned to the feature dynamic weighting vector. Dynamic temperature adjustment triggering conditions and dynamic weight corrections are applied to perform different dynamic numerical corrections on the base power for different age groups, resulting in temperature state correction results for each age group. Based on real-time scenarios, [further details are needed]. P 基础A Correction satisfies: ; α A To adjust the coefficient upwards, , Based on scenarios where the temperature drops too quickly, P 基础A Correction satisfies: ; β A To lower the coefficient, ; Finally, the correction result is mapped onto the non-dead zone. If the output power does not exceed the set safe power output upper limit and is not lower than the power output lower limit, the adjusted output power is obtained. The controller controls the output power control signal to adjust the output power of the semiconductor cooling and heating device 7, thereby adjusting the cooling temperature of the coolant. The output power is then fed back to the data acquisition terminal to collect the wearer's temperature, completing the closed loop of the control system. Based on the human body temperature and comfort feedback, the temperature of the flexible fitting protective film 200 is intelligently adjusted to improve the temperature control system's adaptability to individual needs and enhance thermal management comfort.

[0020] In this invention, if the age in the age stratification is 55 years or older, that is, the age stratification code... A=2， For users aged 55 and above, temperature sensor 5 and heart rate sensor 22 are used to monitor changes in the wearer's body temperature and heart rate at this power level, respectively. The data is fed back to the data acquisition terminal to collect the wearer's temperature and heart rate, complete the closed loop of the control system, and intelligently adjust the patch temperature based on the body temperature and heart rate parameters. This improves the adaptability of the temperature control system to individual needs and enhances thermal management comfort.

[0021] The above description is only a preferred embodiment of the present invention.
