Description

Technical Field

[0001] The present invention belongs to the technical field of body membrane heating, and in particular relates to an intelligent body membrane heating device and method. Background Art

[0002] Conventional body wraps are widely used in various medical treatments. However, these wraps are typically standard sizes, making them difficult to adapt to patients with unique body shapes or specific medical needs. Heating chambers, a key auxiliary device in body wraps, present numerous technical challenges that require urgent resolution.

[0003] Conventional body mask heating chambers in the current medical field primarily utilize a relatively basic technical architecture. Their construction is relatively simple, typically consisting of an insulated chamber, a heating element, and a temperature display. The chamber is typically constructed of standard insulating materials to maintain internal temperature and minimize heat loss. The heating element, typically a resistance wire or heating rod, raises the chamber's temperature through Joule heating generated by the passage of current.

[0004] In terms of the operating process, medical staff need to manually set the target temperature of the heating box based on their experience. This process lacks the support of precise temperature adjustment algorithms, and often can only set the value based on the general impression of past operations. After completing the temperature setting, the body mask is placed in the heating box and starts heating. During the heating process, due to the lack of automated temperature monitoring and feedback mechanism, medical staff need to frequently open the door of the heating box and use external tools such as thermometers to measure the body mask temperature to determine whether the heating process meets expectations.

[0005] In terms of temperature control technology, most existing heating boxes use an open-loop control mode. Once the heating temperature is set, the heating element will continue to work until it is manually turned off by medical staff. This control method cannot adjust the heating power according to the actual temperature changes in the box in real time, which makes it easy for large temperature fluctuations to occur during the heating process. For example, when the power of the heating element is large, after approaching the target temperature, the temperature may continue to rise and exceed the target value due to the failure to reduce the heating power in time, resulting in a temperature overshoot phenomenon; conversely, if the power of the heating element is small, the heating speed may be slow, and the target temperature may not be reached for a long time. The temperature adjustment process takes a long time, and it is impossible to quickly reach a temperature suitable for body membrane heating. In scenarios where every second counts, such as emergency radiotherapy, this seriously affects the treatment efficiency. Summary of the Invention

[0049] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] The expression “including” an element is an “open” expression. The “open” expression only means that the corresponding components or steps exist, and should not be interpreted as excluding additional components or steps.

[0052] In order to achieve the purpose of the present invention, in some embodiments of an intelligent body film heating device, as Figure 1 As shown, the intelligent body film heating device includes: an insulation box (not shown in the figure), a controller 1, a low-voltage power supply 2, a heating element 3 and multiple temperature sensors 4.

[0053] The heating element 3 includes: an upper transparent electric heating film and a lower transparent electric heating film, the body film a is placed between the upper transparent electric heating film and the lower transparent electric heating film, and the edges of the upper transparent electric heating film and the lower transparent electric heating film are both serpentine structures.

[0054] A plurality of temperature sensors 4 are provided on both the upper transparent electric heating film and the lower transparent electric heating film. The temperature sensors 4 are in communication connection with the controller 1. The controller 1 processes the temperature values ​​collected by the temperature sensors 4 using a multi-sensor array combined with a data fusion algorithm, and performs temperature detection on the heating element, so as to detect local overheating or low temperature in a timely manner.

[0055] The low voltage power supply 2 (specifically a DC power supply below 24V) adjusts the PWM duty cycle through the controller 1 (the controller includes: MOSFET or solid-state relay) to control the heating power of the heating element.

[0056] The controller 1 uses a PID combined with feedforward intelligent control algorithm to dynamically adjust the heating process of the body diaphragm until the temperature reaches a preset temperature value.

[0057] Firstly, the present invention adopts an upper transparent electric heating film and a lower transparent electric heating film to sandwich the film.

[0058] In this structure, a double-layer transparent electric heating film tightly sandwiches the body membrane, and the physical contact between the heating film and the body membrane enables heat conduction. The transparent electric heating film can be, but is not limited to, ITO or silver nanowire conductive film, and has extremely high transparency, with a transmittance exceeding 80%. This transparency allows medical staff to clearly observe the positioning of the body membrane during use, an advantage that cannot be matched by existing opaque metal heating films.

[0059] At the same time, traditional heating films often have high edge temperatures and low center temperatures. The edges of the upper transparent electric heating film and the lower transparent electric heating film of the present invention adopt a serpentine structure, which effectively avoids the problem of current concentration, thereby preventing local overheating and achieving uniform heating. The heating uniformity is improved, the temperature difference can be controlled at ≤1°C, and it does not affect the body film positioning observation, solving the problem of traditional heating body films blocking the field of view and uneven heating.

[0060] Secondly, the present invention adopts redundant arrangement of temperature sensors.

[0061] On the surface of the upper transparent electric heating film and the lower transparent electric heating film, multiple (such as 4) temperature sensors are carefully arranged. The temperature state is accurately judged by weighted average or maximum value screening, which avoids the problem of single point failure and greatly improves the reliability of the equipment. Compared with the existing technology that usually uses a single sensor for monitoring, once the sensor fails, it is very easy to cause temperature out of control. The present invention further uses a multi-sensor array combined with a data fusion algorithm to detect local overheating in real time. For example, when the temperature deviation exceeds 3°C, it can quickly trigger the protection mechanism, overcoming the defect of traditional single sensor monitoring that easily ignores local temperature anomalies. In addition, the use of digital sensors (such as DS18B20) and shielded wire transmission effectively reduces the impact of environmental noise on temperature detection.

[0062] Furthermore, the present invention adopts a low-voltage power supply. The low-voltage power supply of the present invention is a DC power supply below 24V, which is used to power the present invention. The heating power is precisely controlled by adjusting the PWM duty cycle through MOSFET or solid-state relay. The low-voltage power supply effectively avoids the risk of leakage, solves the problem of major safety hazards brought about by the use of 220V AC power in some existing technologies, and is also highly efficient. The PWM adjustment method can greatly reduce energy loss and the efficiency can exceed 90%. Rapid heating can be achieved under safe voltage, and the body membrane can reach 40°C within 10 minutes.

[0063] Then, the present invention adopts an intelligent control algorithm that combines PID with feedforward. The principle of this algorithm is to dynamically adjust the PWM output according to the temperature deviation through PID control, and at the same time combine feedforward compensation to adjust the power in advance according to the ambient temperature changes. For example, when the room temperature is low in winter, the initial power is automatically increased. Compared with traditional PID control, the heating rate is increased by 20% after adding feedforward, and the overshoot is reduced to less than 0.3°C. Moreover, the fuzzy PID parameters can be automatically optimized according to historical data to achieve adaptive adjustment, while most of the existing technologies are fixed parameter settings. Through this method of feedforward compensation plus fuzzy adaptive PID, a constant temperature accuracy of ±0.3°C is achieved, which is much higher than the ±1°C of traditional technology, and can adapt well to different environmental conditions.

[0064] The present invention adopts the algorithm to achieve constant temperature control and reduce temperature fluctuations.

[0065] In summary, the present invention discloses an intelligent body membrane heating device, which can realize automatic heating of body membrane sheets, has high heating efficiency and good effect, and has the following beneficial effects:

[0066] First, the heating element of the present invention adopts an upper transparent electric heating film and a lower transparent electric heating film sandwiching a film sheet, which has good light transmittance, good thermal conductivity and uniform heating.

[0067] Second, the present invention adopts redundant temperature sensors to avoid single point failure problems and greatly improve the reliability of the equipment.

[0068] Third, the present invention adopts low-voltage power supply and power regulation, which makes the equipment safer and effectively avoids the risk of leakage. The PWM regulation method greatly reduces energy loss.

[0069] Fourth, the controller of the present invention adopts an intelligent control algorithm combining PID and feedforward to reduce temperature fluctuations and heat up faster.

[0070] In order to further optimize the implementation effect of the present invention, in some other embodiments, the remaining characteristic technologies are the same, except that the intelligent body film heating device further includes: a temperature fuse and an overcurrent protection circuit, the temperature fuse is used to automatically melt at high temperature, and the overcurrent protection circuit is used to provide overcurrent protection;

[0071] The controller sets a dual threshold alarm. When the temperature value detected by the temperature sensor exceeds ±△3℃, the alarm device will sound an alarm.

[0072] Adopting the above-mentioned preferred solution, the present invention adopts a multiple redundant protection method that combines hardware and software. In terms of hardware, a temperature fuse is set to automatically blow when the temperature reaches 72°C, and an overcurrent protection circuit is also provided. In terms of software, a dual-threshold alarm is set, such as an emergency power outage when the temperature exceeds the set value by ±3°C, and a watchdog reset is also provided. This method of combined hardware and software protection and real-time status monitoring is not only faster in response speed, with a fault response time of less than 0.1 seconds, compared to traditional solutions that rely solely on hardware protection, but also can cover software faults, so that the system reliability meets the IEC 60601 standard for medical equipment.

[0073] The device is equipped with multiple over-temperature alarms. When the temperature sensor detects an abnormal rise in temperature inside the chamber, exceeding the safety threshold, it immediately triggers an audible and visual alarm system to alert medical staff. Simultaneously, an automatic power-off function is activated to quickly cut off power to the heating element, preventing damage to the body membrane and potential safety incidents caused by excessive temperatures.

[0074] In order to further optimize the implementation effect of the present invention, in some other embodiments, the remaining characteristic technologies are the same, the difference is that the intelligent body membrane heating equipment also includes: a human-computer interaction device, which is used to display the temperature change curve, fault code and operation instructions inside the insulation box in real time.

[0075] The above preferred solution is adopted to realize visual operation.

[0076] The human-computer interaction device can be, but is not limited to, a touch screen or LCD. Compared to traditional devices that use mechanical knobs and indicator lights, a graphical interface combined with real-time data visualization is more in line with the interactive trends of modern medical devices, significantly reducing operational errors and improving the work efficiency of medical staff.

[0077] In order to further optimize the implementation effect of the present invention, in other embodiments, the remaining characteristic technologies are the same, except that the intelligent membrane heating device further includes: an automatic water injection device, the automatic water injection device includes: a water level sensor, a water injection pipeline, and a water injection valve installed on the water injection pipeline, and the water level sensor is communicatively connected to the controller;

[0078] The controller receives the water level value collected by the water level sensor and controls the water injection valve to open or close to achieve automatic water replenishment.

[0079] With the above preferred solution, when the water level is lower than the standard, the controller automatically opens the water injection valve to replenish water, and automatically closes after it is filled, thus avoiding the tedious manual water injection.

[0080] The present invention adopts an automatic water injection device to realize automatic water injection, thus avoiding the tedious manual water injection.

[0081] In order to further optimize the implementation effect of the present invention, in some other embodiments, the remaining characteristic technologies are the same, the difference is that the intelligent body membrane heating equipment also includes: an automatic cleaning device, the automatic cleaning device includes: a high-pressure nozzle and a brush terminal, the high-pressure nozzle and the brush terminal are respectively communicated with the controller, and the controller controls the high-pressure nozzle and the brush terminal for cleaning.

[0082] By adopting the above preferred solution, an automatic cleaning device is used to achieve automatic cleaning, thereby reducing the workload of medical staff.

[0083] In order to further optimize the implementation effect of the present invention, in some other embodiments, the remaining characteristic technologies are the same, except that the intelligent body film heating device further includes: a water vapor processing device, which includes: a condensed water collection tank and a heating evaporation device;

[0084] The condensed water collection tank is used to collect the water vapor generated during the heating process of the diaphragm;

[0085] The heating evaporation device is used to convert the water in the condensed water collection tank into water vapor and discharge it out of the insulation box.

[0086] When it comes to thermoplastic film treatment, existing heating chambers lack effective solutions for preventing condensation on the film's surface. Medical staff must manually wipe the condensation off the film with a rag or other tool after heating. This is not only cumbersome but can also affect the film's performance due to incomplete wiping.

[0087] By adopting the above-mentioned preferred solution, the present invention does not need to manually wipe the water vapor generated during the heating process of the body membrane, freeing medical staff from tedious manual operations and allowing them to devote more energy to core medical work. At a time when medical resources are tight, it greatly improves resource utilization efficiency.

[0088] Furthermore, based on the above embodiment, the intelligent body membrane heating device also includes: a swing device, which is used to shake the heating element clamped with the body membrane sheet, so that the water vapor on the surface of the heating element and the body membrane sheet flows to the condensation water collection tank.

[0089] By adopting the above preferred solution, all small water droplets of water vapor flow to the condensed water collection tank.

[0090] Existing heating tanks are highly manual in their operation. Medical staff not only need to manually adjust the temperature to meet the heating needs of different membranes, but also frequently refill the water tank and manually clean the equipment after each use. Particularly inconveniently, when heating the membranes, traditional heating tanks easily form condensation on the membrane surface, which medical staff must manually wipe away, significantly increasing their workload.

[0091] However, the present invention adopts an automatic water injection device, an automatic cleaning device, and a water vapor treatment device to effectively simplify the workload of medical staff and improve efficiency.

[0092] It is worth noting that the electrical system of the intelligent body membrane heating device of the present invention adopts multiple insulation protection and leakage protection designs, which can effectively prevent leakage even when used in a humid environment, creating a reliable environment for the safe and stable operation of the equipment and comprehensively ensuring the safety of medical operations.

[0093] In terms of heating speed, the intelligent body mask heating device uses a new, high-efficiency electric heating film as a heating element. This film features rapid and uniform heating. For example, in emergency situations such as radiotherapy, it can quickly raise the temperature inside the chamber to a range suitable for body mask heating. Compared to traditional heating chambers, this significantly shortens the heating time, buying valuable time for emergency treatment.

[0094] The body membrane sheet needs to be cooled and shaped, and different types of diseases require different cooling rates during radiotherapy applications. Regarding membrane cooling control, the controller of the present invention has a built-in refrigeration module that can accurately control the cooling rate of the body membrane sheet during membrane formation on the patient. According to different body membrane materials and membrane formation requirements, corresponding cooling curves are set, and the cooling power is precisely controlled according to the preset curve to ensure a smooth and accurate cooling process, thereby ensuring the stability and accuracy of the membrane formation effect and providing high-quality body membrane support for subsequent treatments.

[0095] In another embodiment, the present invention further discloses a smart body membrane heating method, which utilizes any of the above-mentioned smart body membrane heating devices for heating, comprising:

[0096] Step S101: placing the body film between the upper transparent electric heating film and the lower transparent electric heating film;

[0097] Step S102: setting a preset temperature value of the body membrane;

[0098] Step S103: multiple temperature sensors collect real-time temperature values ​​and send them to the controller, which processes them using a multi-sensor array combined with a data fusion algorithm;

[0099] Step S104: The controller dynamically adjusts the PWM output according to the temperature deviation and, in combination with feedforward compensation, adjusts the heating power of the heating element in advance according to the ambient temperature change;

[0100] Step S105: Repeat steps S103 to S104 until the temperature reaches a preset temperature value, and then the controller adjusts the heating power of the heating element to keep the body membrane at a constant temperature.

[0101] The present invention discloses an intelligent body membrane heating method with a high degree of automation, significantly reducing the labor burden. A temperature sensor monitors the temperature inside the chamber in real time. When the temperature falls below a set value, the heating element automatically activates to raise the temperature. Once the set value is reached, the heating power is automatically reduced or stopped, achieving precise constant temperature control, eliminating the need for frequent manual adjustments by medical staff.

[0102] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
