Description

Technical Field

[0002] In rehabilitation physiotherapy, postoperative care, and chronic pain management, hot and cold therapy plays an important role as a common physical therapy method. Medical protective gear is an instrument or device used to assist in the medical rehabilitation process. It is mainly used to support or enhance the patient's physical function, help them recover their health, improve their quality of life, and cope with various physical injuries or diseases. Traditional medical protective gear usually adopts hot water bottles, ice packs, or modular adhesive structures containing phase change materials, and achieves hot and cold effects through manual replacement.

[0003] Existing medical protective gear, whether applied with heat or cold, is significantly affected by the environment and the heat storage capacity of the materials. The temperature decays rapidly, making it impossible to maintain a stable temperature according to medical advice. Users cannot know the current temperature and skin condition in real time. Heating pads or ice packs cannot dynamically control the temperature, which may result in localized excessively high or low temperatures, potentially causing burns or frostbite, posing significant safety hazards. Medical staff cannot make precise and automated temperature adjustments according to treatment needs, reducing the effectiveness of medical protective gear.

[0004] Therefore, this invention proposes an intelligent medical protective garment with precise temperature control function and its usage method. Summary of the Invention

[0014] A method for using a smart medical protective garment with precise temperature control, the method comprising:

[0015] Step 1: Set the target temperature according to the doctor's order, and obtain multi-point temperature data of the inner cavity of the medical protective gear through four temperature sensors installed inside the medical protective gear;

[0016] Step 2: Perform fusion calculation on the collected multi-point temperature data to obtain the fused temperature value. The fusion calculation formula is as follows:

[0017]

[0018] in: The combined temperature after merging multiple temperatures; This is the i-th temperature acquisition point; Let be the weighting coefficient, satisfying ;

[0019] Step 3: Compare the fused temperature value with the preset target temperature to obtain the temperature error. Input the temperature error into the closed-loop control algorithm, which is based on the PID control algorithm. The PID control algorithm formula is as follows:

[0020]

[0021] in: For output drive signal; The difference between the target temperature and the real-time temperature.

[0025] Step 7: Upload the temperature curve, treatment parameters, and alarm records during the operation.

[0026] The beneficial effects of this invention are:

[0027] 1. When in use, this intelligent medical protective device with precise temperature control works by using a temperature control module, a cooling component, a heating component, and a temperature sensor. The temperature sensor collects the temperature data of the inner wall of the flexible medical fabric pad in real time and transmits it to the temperature control module. Based on the received real-time temperature data and the preset target temperature, the temperature control module uses a PID control algorithm for closed-loop regulation. When the real-time temperature is higher than the target temperature, the temperature control module outputs a cooling drive signal to control the cooling component to work and cool down. When the real-time temperature is lower than the target temperature, the temperature control module outputs a heating drive signal to control the heating component to work and heat up. The temperature sensor provides real-time feedback on temperature changes, and the temperature control module dynamically adjusts its output according to the feedback information until the real-time temperature approaches or reaches the target temperature, thus achieving precise temperature control.

[0028] 2. When in use, this intelligent medical protective gear with precise temperature control works by using a telescopic component and an inclination sensor. The extension and retraction of the electric telescopic cylinder causes the connecting bar to rotate relative to the first connecting block. Since the slider slides in the first through groove and is fixedly connected to the second connecting block, when the connecting bar rotates, the slider will slide in the first through groove, applying a pushing and pulling force to the second support frame, causing the second support frame to rotate and changing the angle between the first and second support frames to adapt to different usage angles of the patient's knee joint. It can also control the reciprocating extension and retraction of the electric telescopic cylinder to achieve the reciprocating rotation of the second support frame, assisting the patient in knee flexion exercises. The inclination sensor monitors the tilt angle of the second support frame in real time and transmits the data to the temperature control module. When the tilt angle of the protective gear is not up to standard, the temperature control module can control the telescopic component according to the preset program to make corresponding adjustments to meet the usage needs of different angles.

[0029] 3. When in use, this intelligent medical protective gear with precise temperature control function can achieve data interaction between the intelligent medical protective gear and external devices through the communication module settings. It can promptly send temperature data to the external terminal device bound to it. Medical staff can use the external terminal device to understand the temperature inside the protective gear at any time, and can also remotely adjust the parameters of the temperature control module according to actual needs. This allows medical staff to remotely monitor the working status of the protective gear and the patient's treatment, track and analyze the patient's treatment process, and provide data support for subsequent treatment plan adjustments.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0044] Please see Figures 1-9This invention provides a technical solution: an intelligent medical protective garment with precise temperature control and its usage method, comprising a first support frame 1, a second support frame 2, a flexible medical fabric pad 3, a connecting plate 4, a temperature control module 5, a cooling component 14, and a heating component 15. The first support frame 1 and the second support frame 2 are arranged in a U-shape. The flexible medical fabric pad 3 is fixedly installed on the inner side of the first support frame 1 and the second support frame 2. The cooling component 14 and the heating component 15 are fixedly installed on the inner wall of the flexible medical fabric pad 3, and are arranged along the direction of the flexible medical fabric pad 3. The connecting plate 4 is installed at the connection between the first support frame 1 and the second support frame 2. On both sides, a first connecting shaft 17 is installed between the first support frame 1 and the second support frame 2 and the connecting plate 4, and the first connecting shaft 17 is fixedly connected to the connecting plate 4. The first connecting shaft 17 is rotatably connected to the first support frame 1 and the second support frame 2. The temperature control module 5 is fixedly installed on one side of the first support frame 1, and the temperature control module 5 realizes closed-loop regulation based on the PID control algorithm. A temperature sensor 16 is fixedly installed on the inner wall of the flexible medical fabric pad 3, and the temperature sensor 16 is installed between the cooling component 14 and the heating component 15. Four temperature sensors 16 are equidistantly arranged along the direction of the flexible medical fabric pad 3, and the temperature sensors 16 are electrically connected to the temperature control module 5.

[0045] When the medical protective gear is worn on the patient's knee joint, the cooling component 14 or heating component 15 is activated to cool or heat the area. The temperature sensor 16 collects the temperature data of the inner wall of the flexible medical fabric pad 3 in real time and transmits it to the temperature control module 5. The temperature sensor 16 is a thermistor sensor. Based on the received real-time temperature data and the preset target temperature, the temperature control module 5 uses a PID control algorithm for closed-loop regulation. When the real-time temperature is higher than the target temperature, the temperature control module 5 outputs a cooling drive signal to control the cooling component 14 to generate cooling energy, which is evenly distributed onto the flexible medical fabric pad 3, lowering the internal temperature of the protective gear. When the real-time temperature is lower than the target temperature, the temperature control module 5 outputs a heating drive signal to control the heating component 15 to generate heat, which is evenly transferred onto the flexible medical fabric pad 3, raising the internal temperature of the protective gear. The temperature sensor 16 provides real-time feedback on temperature changes, and the temperature control module 5 dynamically adjusts its output based on the feedback information until the real-time temperature approaches or reaches the target temperature, achieving precise temperature control.

[0046] The cooling component 14 includes a first graphene layer 1401 and flexible cooling pads 1402. The end face of the first graphene layer 1401 is flush with the end face of the flexible medical fabric pad 3. Multiple flexible cooling pads 1402 are installed and are equidistantly arranged inside the first graphene layer 1401. The flexible cooling pads 1402 are connected in parallel and electrically connected to the temperature control module 5.

[0047] The flexible cooling pads 1402 are made of Peltier sheets. Multiple flexible cooling pads 1402 are equidistantly distributed inside the first graphene layer 1401. When they generate cooling, they can quickly and evenly diffuse the cooling energy by taking advantage of the good thermal conductivity of the first graphene layer 1401. The parallel connection of multiple flexible cooling pads 1402 ensures that even if one flexible cooling pad 1402 fails, it will not affect the normal operation of the other flexible cooling pads 1402. It can also individually control the flexible cooling pads 1402 in a local area when the temperature is too high, so as to cool that area. This improves the reliability and stability of the cooling component 14, so that the smart medical protective device can operate continuously and stably during the cooling process, providing patients with a reliable temperature regulation experience.

[0048] The heating component 15 includes a second graphene layer 1501 and a flexible heating element 1502. The end face of the second graphene layer 1501 is flush with the end face of the flexible medical fabric pad 3. Multiple flexible heating elements 1502 are installed and are equidistantly arranged on the inner side of the second graphene layer 1501. The flexible heating elements 1502 are connected in parallel and electrically connected to the temperature control module 5.

[0049] The flexible heating element 1502 uses Peltier sheets, and multiple flexible heating elements 1502 are equidistantly distributed inside the second graphene layer 1501. When they generate heat, they can quickly and evenly diffuse the heat with the help of the good thermal conductivity of the second graphene layer 1501. The parallel connection of multiple flexible heating elements 1502 ensures that even if one flexible heating element 1502 fails, it will not affect the normal operation of the other flexible heating elements 1502. It can also individually control the flexible heating elements 1502 in the area where the temperature is too low to raise the temperature of that area, which improves the reliability and stability of the heating component 15. This allows the smart medical protective device to operate continuously and stably during the heating process, providing patients with a reliable temperature regulation experience.

[0050] A connecting seat 13 is fixedly installed on the back of the upper end of the first support frame 1. A power module 10 is installed on the back of the first support frame 1. A connecting groove 19 is provided on the side wall of the power module 10, and the connecting seat 13 is correspondingly provided with the connecting groove 19. The cross-sections of the connecting seat 13 and the connecting groove 19 are both T-shaped. The connecting seat 13 is slidably connected to the power module 10, and the power module 10 is electrically connected to the temperature control module 5.

[0051] The T-shaped connection also ensures the stability of the connection between the connector 13 and the connector slot 19, preventing the power module 10 from becoming loose or falling off during use. This ensures that the power supply can continuously and stably power the temperature control module 5. The power module 10 adopts a rechargeable T-shaped battery design, which is convenient for users to replace and charge at any time, ensuring that the protective gear can work continuously and stably. This makes the installation and removal of the power module 10 very convenient. When the power module 10 is damaged, the user can easily slide it off the first support frame 1 for replacement without affecting the normal use of the smart medical protective gear.

[0052] Two metal buckles 7 are fixedly installed on one side of the upper end of the first support frame 1 and one side of the lower end of the second support frame 2, and the two metal buckles 7 are symmetrically arranged. An elastic fixing strap 8 is installed between the two metal buckles 7, and the elastic fixing strap 8 is correspondingly arranged with the metal buckles 7. The elastic fixing strap 8 includes a bandage 801, a hook and loop fastener 802, and a loop fastener 803. The hook and loop fastener 802 and the loop fastener 803 are fixedly installed on the end face of the bandage 801, and the hook and loop fastener 802 is located on one side of the loop fastener 803.

[0053] When wearing smart medical protective gear, wrap the bandage 801 around the body and pass it through the metal buckle 7. Then, attach the hook side 802 and the loop side 803 of the Velcro. Adjust the attachment position according to your needs to achieve a comfortable and secure fixation. The protective gear remains stable during user activities, preventing it from shifting or falling off. It can adapt to the needs of users with different body sizes. Utilizing the elasticity of the elastic fixing band 8 and the properties of the Velcro, the protective gear is securely fixed to the corresponding part of the body.

[0054] The lower end of the first support frame 1 and the upper end of the second support frame 2 are both provided with protruding teeth 12, and the first support frame 1 and the second support frame 2 are connected by the meshing of the protruding teeth 12. The first support frame 1 and the second support frame 2 are both provided with a second through groove 11, and the second through groove 11 is arc-shaped. A second connecting shaft 18 is slidably installed inside the second through groove 11, and the second connecting shaft 18 is fixedly connected to the connecting plate 4.

[0055] The meshing connection of the teeth 12 ensures a tight and stable connection between the first support frame 1 and the second support frame 2, preventing loosening or displacement during use. The arc-shaped design of the second through groove 11 and the sliding installation of the second connecting shaft 18 within it allow the connecting plate 4 to be flexibly adjusted according to actual needs. When the user needs to wear or adjust the protective gear, the connecting plate 4 can slide along the second through groove 11 to adapt to different body parts and postures.

[0056] A telescopic assembly 9 is installed on one side of the first support frame 1 and the second support frame 2. The telescopic assembly 9 includes a connecting bar 901, an electric telescopic cylinder 902, a first connecting block 903, a second connecting block 904, a slider 905, and a first through groove 906. The first connecting block 903 is fixedly installed on one side of the first support frame 1, and the second connecting block 904 is fixedly installed on one side of the second support frame 2. The electric telescopic cylinder 902 is installed below the first connecting block 903, and the body of the electric telescopic cylinder 902 is rotatably connected to the first connecting block 903. The connecting bar 901 is installed on one side of the second connecting block 904, and one end of the connecting bar 901 is rotatably connected to the telescopic end of the electric telescopic cylinder 902. The first through groove 906 is provided on the connecting bar 901 and is elongated. The slider 905 is slidably installed inside the first through groove 906 and is fixedly connected to the second connecting block 904.

[0057] The extension and retraction of the electric telescopic cylinder 902 causes the connecting bar 901 to rotate relative to the first connecting block 903. Since the slider 905 slides in the first through groove 906 and is fixedly connected to the second connecting block 904, when the connecting bar 901 rotates, the slider 905 will slide in the first through groove 906, thereby changing the angle between the first support frame 1 and the second support frame 2 to adapt to different use angles of the patient's knee joint. It can also assist the patient's knee joint bending exercise by controlling the reciprocating extension and retraction of the electric telescopic cylinder 902. In actual use, the patient only needs to use simple operation commands to make the protective gear quickly adjust to the appropriate angle, which improves the patient's user experience.

[0058] An inclination sensor 20 is fixedly installed on one side of the second support frame 2, and the inclination sensor 20 is electrically connected to the temperature control module 5.

[0059] The tilt sensor 20 can monitor the tilt angle of the second support frame 2 in real time and transmit the data to the temperature control module 5. When the tilt angle of the protective gear changes abnormally, the temperature control module 5 can control the telescopic component 9 according to the preset program to make corresponding adjustments.

[0060] A communication module 6 is fixedly installed at the front of the lower end of the second support frame 2, and the communication module 6 is electrically connected to the temperature control module 5.

[0061] The communication module 6 enables data interaction between the smart medical protective gear and external devices, and promptly sends temperature data to the bound external terminal devices, such as a mobile APP or a monitoring platform for medical staff. Medical staff can use the external terminal devices to understand the temperature inside the protective gear at any time, and can also remotely adjust the parameters of the temperature control module 5 according to actual needs. This facilitates remote monitoring of the protective gear's working status and the patient's treatment, allowing for tracking and analysis of the patient's treatment process and providing data support for subsequent treatment plan adjustments.

[0062] A method for using a smart medical protective garment with precise temperature control, the method comprising:

[0063] Step 1: Set the target temperature according to the doctor's order, and obtain multi-point temperature data of the inner cavity of the medical protective gear through four temperature sensors 16 installed inside the medical protective gear;

[0064] Step 2: Perform fusion calculation on the collected multi-point temperature data to obtain the fused temperature value. The fusion calculation formula is as follows:

[0065]

[0066] in: The combined temperature after merging multiple temperatures; This is the i-th temperature acquisition point; Let be the weighting coefficient, satisfying ;

[0067] Step 3: Compare the fused temperature value with the preset target temperature to obtain the temperature error. Input the temperature error into the closed-loop control algorithm, which is based on the PID control algorithm. The PID control algorithm formula is as follows:

[0068]

[0069] in: For output drive signal; The difference between the target temperature and the real-time temperature. This is the proportionality coefficient; For integral limiting; The integral coefficient; For integration variables; The rate of change of error; These are the differential coefficients;

[0070] Step 4: Control the cooling or heating unit inside the protective gear according to the output drive signal to perform heating or cooling actions;

[0071] Step 5: Re-collect the internal temperature of the medical protective gear after temperature control adjustment and return to Step 2 to recalculate and control;

[0072] Step Six: When overheating, abnormal temperature rise, or temperature sensor failure is detected, trigger power-off protection and alarm prompts;

[0073] Step 7: Upload the temperature curve, treatment parameters, and alarm records during the operation.

[0074] Working principle: See Figure 1 , Figure 2 and Figure 9As shown, the medical protective gear is worn on the patient's knee joint. The elastic fixing strap 8, through the cooperation of the hook side 802 and the loop side 803 of the Velcro, can firmly fix the protective gear to the patient's body. When the smart medical protective gear starts to work, the cooling component 14 or the heating component 15 is turned on to cool down or heat up. The temperature sensor 16 collects the temperature data of the inner wall of the flexible medical fabric pad 3 in real time and transmits it to the temperature control module 5. The temperature control module 5 uses a PID control algorithm to perform closed-loop regulation based on the received real-time temperature data and the preset target temperature.

[0075] See Figure 2 and Figure 7 As shown, when the real-time temperature is higher than the target temperature, the temperature control module 5 will output a cooling drive signal to control the cooling component 14 to work. Multiple flexible cooling pads 1402 connected in parallel will start cooling. The cold energy will be evenly distributed to the flexible medical fabric pad 3 through the first graphene layer 1401, which will reduce the internal temperature of the protective gear. As the temperature decreases, the temperature sensor 16 will provide real-time feedback on the temperature change. The temperature control module 5 will dynamically adjust the output according to the feedback information until the real-time temperature approaches or reaches the target temperature.

[0076] See Figure 2 and Figure 8 As shown, when the real-time temperature is lower than the target temperature, the temperature control module 5 will output a heating drive signal to control the heating component 15 to work. Multiple flexible heating elements 1502 connected in parallel will start to generate heat. The heat will be evenly transferred to the flexible medical fabric pad 3 through the second graphene layer 1501, thereby increasing the temperature inside the protective gear. As the temperature rises, the temperature sensor 16 continuously feeds back the real-time temperature, and the temperature control module 5 continuously adjusts the output drive signal to achieve precise temperature control.

[0077] See Figure 1 , Figure 3 and Figure 4 As shown, during use, the telescopic component 9 can adjust the distance between the first support frame 1 and the second support frame 2 according to actual needs. The telescopic end of the electric telescopic cylinder 902 drives the connecting strip 901 to move, and the slider 905 slides in the first through groove 906 to change the angle between the first support frame 1 and the second support frame 2, adapting to different use angles of the patient's knee joint. It can also assist the patient's knee joint bending exercise by controlling the reciprocating telescopic extension and retraction of the electric telescopic cylinder 902. The first support frame 1 and the second support frame 2 are connected by the meshing of the convex teeth 12, and with the sliding connection of the second through groove 11 and the second connecting shaft 18, the stability of the protective gear during the adjustment process is ensured.

[0078] See Figure 1As shown, the tilt sensor 20 can monitor the tilt angle of the protective gear in real time and transmit the data to the temperature control module 5. When the tilt angle of the protective gear changes abnormally, the temperature control module 5 can make corresponding adjustments according to the preset program. The communication module 6 can realize the communication between the protective gear and external devices, which makes it convenient for medical staff to remotely monitor the working status of the protective gear and the treatment of patients.

[0079] It should be noted that the temperature control module 5, communication module 6, electric telescopic cylinder 902, power supply module 10, flexible cooling plate 1402, flexible heating plate 1502, temperature sensor 16 and tilt sensor 20 mentioned above can be powered by existing operating techniques. Whether the power supply is provided by the power supply component or by an external wire, it is all a conventional operating technique and will not be described in detail here.

[0080] Example:

[0081] Four temperature sensors were installed at the front of the knee (T1), the back of the knee (T2), the medial ligament area of ​​the knee (T3), and the lateral ligament area of ​​the knee (T4), respectively.

[0082] Weighting is based on the fact that the area around the knee is most sensitive to temperature, followed by the ligament areas on both sides of the knee. The weighting is configured as follows:

[0083]

[0084] Data fusion uses a weighted average:

[0085]

[0086] Target temperature: 40℃; Temperature control accuracy: ±0.25℃; Heating time: 45 seconds;

[0087] The flexible cooling and heating elements are driven by PWM controlled by an MCU.

[0088] When the initial temperature difference is large, use high duty cycle heating.

[0089] As the target temperature approaches, the duty cycle is dynamically reduced.

[0090] Isothermal phase → Enter fine-tuning mode (sample every 0.2 seconds).

[0091] Security Policy:

[0092] The rate of temperature rise must not exceed 0.8℃ / min;

[0093] The temperature at a single point must not exceed 45℃;

[0094] If the temperature gradient in abnormally sensitive skin areas (T3 / T4) is greater than ΔT>1.5℃, the power will be automatically reduced.

[0095] Automatic reminder when cumulative heating time reaches ≥30 minutes.
