Description

Technical Field

[0001] The present invention relates to the technical field of surgical operations, and in particular to a non-invasive, wireless, wearable, flexible film temperature measurement matrix system. Background Art

[0002] Microvascular free tissue transplantation (free flap) is an indispensable classic surgical method in the fields of orthopedics, microsurgery, and plastic surgery. It can be applied to large soft tissue defects in various parts of the body. Since its introduction in 1950, free flaps have become a widely used reconstructive surgery. In the past two decades, although the surgical technology has become increasingly mature, the success rate of free flaps has remained stagnant at around 95%, and about 5% of the operations will fail, requiring urgent exploration of blood vessels to save the flap. Therefore, early identification and monitoring of clinical signs that may lead to flap failure is the key to further improving flap survival rates.

[0003] Studies have shown that flap failure mainly occurs within the first 72 hours, and the salvage rate is usually related to the time when vascular damage is discovered. At present, it is commonly used in clinical practice for staff with experience in free flap monitoring to perform frequent clinical examinations of flaps, usually by specialist nurses. The nursing team evaluates the flap every hour in the first 24 hours, and then every 2 hours for the next 48 hours. Flap evaluation includes examination of flap temperature, filling, capillary filling, and color. However, nurses who are proficient in microvascular care are very rare and valuable, and frequent testing is very labor-intensive. Especially in grassroots hospitals, nursing staff may not be familiar with flap physiology. In addition, patients may find long-term and frequent monitoring a disturbance and discomfort. Therefore, designing and inventing an effective flap monitoring technology and equipment is an urgent problem to be solved in clinical practice.

[0004] In recent years, the development of auxiliary flap monitoring technologies has improved surgical success rates, including reduced complications, increased efficiency, shortened hospital stays, and improved overall outcomes. Flap monitoring technologies can be classified based on attributes such as monitoring mechanism (measuring vascular flow vs tissue ischemia), duration of use (intraoperative vs postoperative), and invasiveness (non-invasive vs invasive). Technologies that monitor vascular flow include handheld Doppler ultrasound, implantable Doppler ultrasound, color duplex ultrasound, fluorescein angiography, and laser Doppler flowmetry. Technologies that monitor tissue metabolism and ischemia include near-infrared spectroscopy and microdialysis. Other technologies under development include thermal imaging, pH monitoring, transit time volume flow measurement, and spatial domain frequency imaging.

[0005] In the prior art, each method has some problems: Handheld Doppler Ultrasound Technology Disadvantages include difficulty distinguishing signal sources, such as from recipient vessels and vascular pedicles, and lack of quantitative measurements. In addition, this ultrasound detection technology requires experienced sonographers or radiologists to operate, increasing patient waiting time and hospital operating costs.

[0006] Implantable Doppler ultrasound Disadvantages include lack of quantitative measurement and invasiveness (although placement and removal are relatively simple). Another common disadvantage is that the sound signal may fade when monitoring is continued over multiple days.

[0007] Color Doppler ultrasound The disadvantage is that it requires an experienced sonographer or radiologist to perform the study. Also, it is difficult to obtain frequent monitoring, and the current technology is not designed for continuous monitoring.

[0008] Fluorescein angiography Disadvantages include the non-continuous “snapshot” nature of the captured data, the high cost of the device, and the relative contraindications for use in patients with iodide allergy or renal failure. Additionally, while frequent use is possible, the large size and cost of the device limits the ability to maintain postoperative monitoring at the bedside. Due to the non-continuous nature of its use, it is not recommended as a primary tool for flap monitoring.

[0009] Laser Doppler blood flowmeter Disadvantages include high cost, sensitivity to tiny blood vessel movement, lack of threshold to indicate flap failure, and the need for professional intervention and interpretation of instrument data.

[0010] Tissue oximeter Disadvantages include high cost, the fact that the values ​​they report are relative rather than absolute, and the need for trending of individual patients rather than comparison to set thresholds.

[0011] microdialysis Disadvantages include invasiveness, non-continuous reading, time delay between sampling and results, and high cost, which hinder its clinical application and promotion. Summary of the invention

[0012] In view of the deficiencies in the prior art, the present invention provides a non-invasive wireless wearable flexible thin film temperature measurement matrix system to solve the problems raised in the above background technology.

[0013] To achieve the above object, the present invention provides the following technical solutions: a non-invasive wireless wearable flexible film temperature measurement matrix system, comprising a flexible film and a quality assessment module, wherein the flexible film is divided into a temperature measurement area and a wireless sensing area, wherein the temperature measurement area covers a transplanted skin flap, wherein a high-sensitivity temperature measuring resistor matrix is ​​integrated in the temperature measurement area, and wherein a skin flap area temperature measurement receiving component is integrated in the wireless sensing area; The quality assessment module is built into an external device, which includes a mobile terminal and a computer terminal.

[0019] To further optimize the technical solution, the temperature data processing algorithm includes temperature data filtering and data smoothing processing; Temperature data filtering uses Kalman filtering or median filtering to remove high-frequency noise in the data, sets a time window, and smoothes the current measurement value based on several past measurement data; Data smoothing uses exponentially weighted moving average (EWMA) or sliding average to weight the temperature data, eliminating short-term fluctuations and ensuring trend stability.

If the temperature in individual areas is obviously,higher or lower, a thermal map analysis algorithm is used to detect,local temperature anomalies.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0027] See also Figure 1A non-invasive wireless wearable flexible film temperature measurement matrix system includes a flexible film and a quality assessment module. The flexible film is divided into a temperature measurement area 1 and a wireless sensing area 2. The temperature measurement area 1 covers the transplanted skin flap. The temperature measurement area 1 is integrated with a high-sensitivity temperature measuring resistor matrix. The wireless sensing area 2 is integrated with a skin flap area temperature measurement receiving component.

[0028] The flexible film is biocompatible and is made of a biocompatible material, polydimethylsiloxane (PDMS). It has good elasticity and flexibility, and can fit closely to the skin surface without causing skin irritation or allergic reactions. As the basic carrier of the entire system, it ensures seamless contact between the device and human skin, and provides stable physical support for the temperature measuring resistor matrix.

[0029] The high-sensitivity temperature measuring resistor matrix is ​​composed of at least five high-precision temperature sensitive resistors 3, and is used to measure the temperature change of the skin surface; The temperature sensitive resistors 3 are arranged in a matrix form, covering the central area and the edge area of ​​the skin flap respectively, and are used to provide detailed data of temperature distribution, which is helpful to detect local body temperature changes on the skin flap and identify abnormal areas.

[0030] The skin flap area temperature measurement receiving component includes a temperature acquisition module, a data transmission module, and a wearable antenna 6; The temperature acquisition module is used to receive the resistance change signal transmitted by the temperature sensitive resistor 3, and convert the signal into corresponding temperature data, and convert the resistance change into an electrical signal; The data transmission module is used to wirelessly transmit the collected temperature data to an external quality assessment module, thereby receiving the body temperature data in real time; The wearable antenna 6 is used to cooperate with the data transmission module and ensure the effective transmission of wireless signals.

[0031] In this embodiment, in the flap area temperature measurement receiving component: The temperature acquisition module uses a temperature acquisition chip 4.

[0032] The data transmission module adopts Wifi / Bluetooth chip 5. The Bluetooth chip can achieve stable and fast data transmission within a short distance and quickly establish a connection with a nearby receiving device; the Wifi wireless transmission chip can transmit data to a designated receiving end within a larger range, such as in an area covered by a Wifi network.

[0033] The wearable antenna 6 adopts a conformal antenna to ensure the radiation efficiency of the antenna while ensuring a close fit with the skin flap.

[0034] The quality assessment module is built into an external device, which includes a mobile terminal and a computer terminal, and can also be installed as an APP on a portable device. It can be directly wirelessly connected to the temperature measurement receiving component in the flap area, or wirelessly connected through a mobile phone base station to obtain temperature data of the flap position in real time, and judge the temperature data obtained by each high-sensitivity temperature measuring resistor to determine whether the flap transplantation is normal. This module is used to determine whether the temperature of the flap is within the normal range and whether there is an abnormal temperature change trend, providing medical staff or related personnel with important reference information on the quality and health of the flap.

[0035] In this embodiment, the quality assessment module uses a preset algorithm mechanism to assess the state of the skin flap, and the algorithm mechanism includes a temperature data processing algorithm, a temperature change trend analysis algorithm, a temperature threshold determination criterion, a comprehensive assessment algorithm and an alarm mechanism.

[0036] Wherein, the temperature data processing algorithm includes temperature data filtering and data smoothing processing; Temperature data filtering uses Kalman filtering or median filtering to remove high-frequency noise in the data, sets a time window, and smoothes the current measurement value based on several past measurement data; Data smoothing uses exponentially weighted moving average (EWMA) or sliding average to weight the temperature data, eliminating short-term fluctuations and ensuring trend stability.

[0037] Among them, the temperature change trend of the skin flap is the key to judging its health status. Generally speaking, the temperature of the skin flap should be kept within a certain range under normal circumstances, and the temperature change is gentle. Common analysis methods include temperature change rate analysis, thermal map analysis and local temperature anomaly detection; Temperature change rate analysis, by calculating the temperature change rate of the flap area, identifies the area with drastic temperature changes. Under normal circumstances, the temperature should be in a relatively stable range. If the temperature change rate exceeds the preset threshold, it may be due to an abnormal reaction caused by local ischemia, infection, etc.; Thermal map analysis and local temperature anomaly detection, based on the collected temperature measurement matrix data, generate a thermal map of the flap area. If the temperature in some areas is significantly higher or lower, a thermal map analysis algorithm can be used to detect local temperature anomalies. For example, using thermal anomaly detection or local anomaly detection (LAD) methods, compare the current temperature with the temperature difference of the surrounding area.

[0038] Among them, according to the physiological characteristics of the skin after flap transplantation, the temperature usually fluctuates within a certain range. Too high or too low temperature of the flap may mean blood circulation problems, infection or other health problems. The following standards can be set: (1) Normal temperature range After flap transplantation, the temperature of a healthy flap should be maintained within a certain range, usually between 30°C and 37°C. The specific range can be appropriately adjusted according to the site of flap transplantation, surgical conditions, and individual differences.

[0039] (2) Too high temperature (warning range) If the flap temperature rises above 38°C, it may indicate local inflammation or infection. At this time, an early warning is needed, and medical staff are advised to check the flap status and perform further intervention.

[0040] (3) Too low temperature (warning range) If the temperature of the flap drops below 28°C, it may indicate insufficient blood supply or ischemia. Immediate measures are needed to ensure normal blood circulation.

[0041] Among them, the comprehensive evaluation algorithm includes abnormal temperature trend detection, abnormal temperature distribution pattern recognition, and flap health scoring; Abnormal temperature trend detection: if the temperature in a specific area of ​​the flap is continuously too high or too low, and the temperature trend does not meet expectations, an alarm will be issued, indicating possible ischemia, infection or other abnormal conditions; Abnormal temperature distribution pattern recognition: perform pattern recognition on the temperature distribution of each area of ​​the flap. If the temperature change pattern of some areas is found to be significantly different from the normal state, the area where the problem may occur can be quickly located. The flap health score uses a weighted scoring system to calculate a health score for each flap area by comprehensively considering the temperature data and change trends of each temperature measurement point. For example, areas with normal temperatures are given higher scores, while areas with abnormal temperatures are given lower scores. Ultimately, these scores can be combined to derive an overall flap health score to help medical staff make decisions.

[0042] In the alarm mechanism, if the temperature data exceeds the threshold range or shows an abnormal trend, the system should immediately trigger an alarm and remind the user. The alarm content can be sent to medical staff via SMS, email, mobile push notification, etc. Embodiment 2
