Description

TECHNICAL FIELD

[0001] The present application relates to the field of warning devices, in particular to a postoperative upper limb excessive force warning device. BACKGROUND

[0002] In the modern rehabilitation management after tumor treatment, scientific monitoring and management of postoperative lymphedema are particularly important. Due to work and activity habits, rehabilitation patients often ignore medical advice and inadvertently frequently perform inappropriate lifting, pulling, pushing and other overload force behaviors, which often leads to postoperative lymphedema, seriously affecting the rehabilitation of patients. However, there is currently no device that can monitor the force of the patient's upper limbs in real time and warn against inappropriate force behaviors. CONTENT OF THE UTILITY MODEL

[0003] Therefore, in the embodiments of the present application, a postoperative upper limb excessive force warning device is provided, which can be used to collect the force of the arm in real time through a bracelet wearing method for postoperative rehabilitation patients, and can perform a buzzing warning for overload force conditions, so as to correct the activity behavior of the patient in time and help improve the postoperative rehabilitation effect.

[0004] Therefore, in the embodiments of the present application, the following technical solutions are adopted:

[0005] A postoperative upper limb excessive force warning device, comprising: a watch body, an accommodating space being formed inside the watch body; a processing module, installed in the accommodating space inside the watch body; at least one thin film pressure sensor, electrically connected with the processing module, at least one thin film pressure sensor being arranged at a corresponding upper limb force monitoring position of a postoperative rehabilitation patient, for collecting pressure data of the thin film pressure sensor when the monitoring position is forced, and sending the pressure data to the processing module; and an alarm module, installed in the accommodating space of the shell, electrically connected with the processing module, for receiving the pressure data sent by the processing module and generating an alarm prompt.

[0006] In this embodiment, through the thin film pressure sensor, the device can collect and monitor the force of the upper limbs in real time, ensuring that overload force behaviors are discovered in time. Then, the integrated alarm module can immediately issue a buzzing warning when inappropriate force is detected, helping the patient to correct the behavior in time and reducing the risk of postoperative lymphedema. In addition, the watch body in this embodiment can be worn in the form of a bracelet for force condition monitoring, which is convenient and comfortable to use and does not cause too much interference to the daily life of the patient. The processing module processes the pressure data and generates a warning, instructing the alarm module to generate an alarm. In this way, the warning device of the present embodiment prevents inappropriate force and reduces the occurrence of lymphedema, which helps the patient to recover better and improves the overall treatment effect.

[0007] As an implementable embodiment, the thin-film pressure sensor is provided with a waterproof layer on one side.

[0008] In this embodiment, the waterproof layer provided on one side of the thin-film pressure sensor can effectively improve the performance, reliability and applicability of the sensor, especially in the case of possible moisture, humidity or potential liquid presence at the human monitoring site.

[0009] As an implementable embodiment, the waterproof layer comprises a polycarbonate film waterproof layer.

[0010] In this embodiment, the polycarbonate film waterproof layer has excellent waterproof performance and can effectively prevent water from entering the sensor. At the same time, polycarbonate has good resistance to a variety of chemicals, which can protect the sensor from chemical corrosion. Polycarbonate is wear-resistant, impact-resistant and can withstand various environmental conditions, prolonging the service life of the sensor.

[0011] In some embodiments, the material of the waterproof layer can also be any one of a polyurethane film, a silicone film, a polytetrafluoroethylene (PTFE) film, an ethylene-vinyl acetate copolymer (EVA) film, a polyamide film (nylon film), and a polyvinyl chloride (PVC) film. Users can choose appropriate waterproof layer materials according to actual application requirements and environmental conditions.

[0012] As an implementable embodiment, the thin-film pressure sensor is provided with a sensor gasket layer on the side facing the monitoring site.

[0013] In this embodiment, the sensor gasket layer can fill the gap between the thin-film pressure sensor and the monitoring site, increasing the effective contact between the thin-film pressure sensor and the monitoring site. In other words, the sensor gasket layer can provide a uniform contact surface, reducing pressure measurement errors caused by uneven surfaces or poor contact, which helps to improve the stability and measurement accuracy of the sensor. Moreover, the gasket layer can make the sensor better adapt to the human body surface or other irregularly shaped monitoring sites, improving the comfort and adaptability of use.

[0014] As an implementable embodiment, the sensor gasket layer is a medical silicone layer.

[0015] In this embodiment, the medical silicone has excellent biocompatibility and does not cause skin allergies or discomfort, making it suitable for long-term contact with the skin, which is particularly important when used in medical devices. Silicone has good flexibility and elasticity, allowing the sensor to adapt to different shapes of arms, providing a comfortable wearing experience and not causing pressure on the skin. The lightweight silicone material does not increase the burden of wearing, improving the overall comfort and wearability of the device. Medical silicone can work well with the pressure sensor, providing stable pressure sensing capability, allowing the sensor to accurately capture and transmit pressure data.

[0016] As an implementable embodiment, the thin film pressure sensor comprises a long tail interface for signal connection with the processing module, and the long tail interface is used to extend the distance between the thin film pressure sensor and the surface body.

[0017] In this embodiment, the long tail interface allows the sensor and the processing module to maintain an appropriate distance, so that the sensor can be installed at a distance from the processing module, enhancing the layout flexibility of the warning device.

[0018] As an implementable embodiment, a reserved hole is provided on the surface body, and the reserved hole is used for electrical connection between the long tail interface of the thin film pressure sensor and the processing module.

[0019] As an implementable embodiment, the thin film pressure sensor comprises an adhesive layer for fixing the thin film pressure sensor on the surface body or the elastic sleeve.

[0020] In this embodiment, the adhesive layer allows the sensor to be easily fixed on various surfaces without the need for additional fixing devices or tools. This simplifies the installation process and improves the convenience of use. For example, the thin film pressure sensor can be conveniently fixed at a designated position on a bracelet or elastic sleeve using an adhesive layer (such as double-sided tape) according to the needs of the monitoring site.

[0021] As an implementable embodiment, the surface body is provided with a display screen for displaying pressure data, and the opposite sides of the surface body are respectively provided with watchbands for fixing the surface body on the corresponding upper limb force monitoring site of the postoperative rehabilitation patient.

[0022] In this embodiment, the display directly shows real-time pressure data from the thin-film pressure sensor, allowing users to access and monitor relevant pressure information in real-time. This is particularly important for postoperative rehabilitation patients, as it provides immediate feedback to help them understand their progress and exertion levels. The watch body is secured to the patient's upper limb at the desired monitoring location using a watchband. The watchband is designed with comfort and stability in mind, ensuring that the device remains in place during use, regardless of movement or other factors, thereby ensuring the accuracy of the measurement data. The watchband is designed to be adjustable, allowing it to accommodate patients of different sizes and shapes, ensuring that the device fits snugly and securely in place regardless of the size and shape of the patient's arm.

[0023] As an implementable embodiment, the warning device further comprises an AO-RES amplification adjustment potentiometer, wherein the thin-film pressure sensor is connected to the processing module through the AO-RES amplification adjustment potentiometer.

[0024] In this embodiment, the thin-film pressure sensor is responsible for collecting pressure signals applied to its surface. The sensor converts physical pressure into an electrical signal, which is usually very weak and may not be sufficient for direct use in subsequent processing or warning functions. Since the signal output by the sensor may be small, it needs to be amplified by an amplifier. The AO-RES amplification adjustment potentiometer is an adjustable amplifier that allows users to adjust the amplification of the signal according to their needs. This adjustment function allows the device to optimize signal strength according to the actual application scenario. The adjusted signal is transmitted to the processing module. For example, the processing module may include signal filtering, data analysis, and implementation of warning functions. The adjusted signal can improve the accuracy and reliability of signal processing by the processing module, thereby generating accurate warning information. In this way, by adjusting the amplification, the signal can be ensured to be within the optimal amplitude range before processing, thereby avoiding the problem of signal being too weak or too strong. This optimization can improve the overall accuracy and response speed of the device.

[0025] As an implementable embodiment, the warning device further comprises a DO-RES comparison threshold adjustment potentiometer connected to the processing module.

[0026] In this embodiment, the potentiometer is an adjustable resistor used to set a voltage threshold. After connecting the potentiometer to the processing module, the threshold voltage can be adjusted for comparison with the sensor output signal. The processing module obtains the signal output by the sensor (such as a pressure data signal) and converts it into a corresponding electrical signal, which is then compared with the threshold set by the potentiometer. When the electrical signal reaches or exceeds the set threshold, the processing module will issue a corresponding warning signal, and the warning signal is used to instruct the buzzer warning module to issue a buzzer warning.

[0027] As one implementation can be realized, the warning device further comprises a power module, which provides operating power for the warning device.

[0028] As one implementation can be realized, the processing module comprises a single-chip microcomputer.

[0029] As one implementation can be realized, the warning device further comprises a memory, which is connected with the processing module and used for storing the pressure data.

[0030] In summary, the warning device can be specially used for postoperative rehabilitation patients to collect the force condition of the arms in real time through the wearing of the bracelet, to give a buzzer warning for the overloading force condition, to correct the activity behavior of the patients in time, and to help improve the postoperative rehabilitation effect.

[0041] Lymphedema is caused by lymphatic circulation disorders, which cause lymphatic fluid to accumulate in the interstitial space, leading to a condition of fluid accumulation in the body tissue. It is commonly found in arms, legs or other parts, and the main manifestations include some pathological changes such as tissue edema, chronic inflammation and tissue fibrosis, and symptoms include swelling, heaviness, pain or tightness, which can seriously affect the activity and quality of life. Lymphedema is usually caused by the following reasons: 1. Primary lymphedema: usually caused by congenital lymphatic system development. 2. Secondary lymphedema: often caused by trauma, infection, surgical resection (such as resection of lymph nodes during cancer surgery) or radiotherapy and other factors affecting the lymphatic system.

[0042] The treatment methods of lymphedema usually include physical therapy (such as lymphatic drainage massage), compression therapy, skin care, and in some cases, drug or surgical treatment. Among them, early diagnosis and intervention after surgery can effectively control the symptoms of lymphedema and prevent the disease from worsening. In the embodiments of the present application, the upper limb overload activity warning for preventing postoperative lymphedema mainly refers to preventing patients from frequently overloading after tumor diagnosis and treatment. Scientific monitoring and management of postoperative lymphedema are particularly important in modern rehabilitation management after tumor treatment. Rehabilitation patients often neglect medical advice due to work and activity habits, and inadvertently frequently perform inappropriate overloading behaviors such as lifting, pulling and pushing, which often leads to postoperative lymphedema, seriously affecting the rehabilitation of patients. However, there is currently no device that can monitor the force of the patient's upper limbs in real time and warn against inappropriate force behaviors.

[0043] Therefore, the present application is committed to providing a postoperative upper limb overloading force warning device, which can be used for real-time collection of arm force conditions of postoperative rehabilitation patients through wristband wearing, and can perform buzzer warning for overloading force conditions, so as to correct the activity behavior of patients in time and help improve the postoperative rehabilitation effect.

[0044] Figure 1 A perspective structural schematic diagram of a postoperative upper limb overloading force warning device provided by an embodiment of the present application is shown. As shown in the figure, the device comprises a bracelet 1, a force sensor 2, a microcontroller 3, a buzzer 4 and a power supply 5.Figure 1 As shown, the warning device includes a meter body 121, a circuit board 122 installed in the internal space of the meter body 121, and a thin film pressure sensor 110. Optionally, the circuit board 122 integrates a processing module 1220, an alarm module 1224, an AO-RES amplification adjustment potentiometer 1222, and a DO-RES comparison threshold adjustment potentiometer 1223.

[0045] The watch body 121 is a waist-shaped strip, and a reserved hole 1210 is provided at one end of the watch body 121. The thin film pressure sensor 110 includes a long tail interface 1100 for signal connection with the processing module 1220. The long tail interface 1100 is used to extend the distance between the thin film pressure sensor 110 and the watch body 121, and the long tail interface 1100 is connected to the processing module 1220 through the reserved hole 1210. Accordingly, an input interface 1221 is provided on the circuit board 122. After the long tail interface 1100 passes through the reserved hole 1210 and enters the interior of the watch body 121, it is connected to the processing module 1220 through the input interface 1221. In some embodiments, the processing module 1220 is provided with a BLUETOOTH unit and / or a WiFi unit, and the processing module 1220 is connected to the thin film pressure sensor 110 via the BLUETOOTH unit and / or the WiFi unit to further improve the applicability of the thin film pressure sensor 110.

[0046] It should be noted that after the pressure data acquired by the thin film pressure sensor 110 is transmitted to the input interface 1221 on the circuit board 122, it needs to be adjusted and optimized by the AO-RES amplification adjustment potentiometer 1222. The AO-RES amplification adjustment potentiometer 1222 transmits the optimized pressure data signal to the processing module 1220. The processing module 1220 converts the pressure data signal of the pressure change sensed by the sensor into an electrical signal of corresponding intensity change, and compares it with the voltage threshold set by the DO-RES threshold adjustment potentiometer 1223 based on the rehabilitation patient's force standard. When the electrical signal reaches or exceeds the set voltage threshold, the processing module 1220 will issue a corresponding warning signal. The warning signal is used to instruct the alarm module 1224 to issue an alarm prompt, so as to promptly correct the patient's excessive force activity behavior, which helps to improve the postoperative rehabilitation effect. Optionally, the alarm module 1224 is a buzzer, and the alarm module 1224 generates a buzzer alarm after receiving the alarm signal sent by the processing device.

[0047] Continue reading Figure 1Optionally, the watch body 121 is provided with a display screen 1211, which is used to display the numerical value of the pressure data obtained by the thin film pressure sensor 110, so as to facilitate the user to view. In an embodiment, the display screen 1211 is a touch display screen 1211, and the user can control the DO-RES comparison threshold adjustment potentiometer 1223 to set the alarm voltage threshold through the touch display screen 1211. The voltage threshold can be set based on the standard force of the rehabilitation patient, or a default threshold can be selected, and the default threshold is set to be that the voltage signal does not exceed 2.2V, which is not strictly limited in this embodiment. For example, in order to facilitate the warning of the equipment, a watch strap is arranged at each of the opposite ends of the watch body 121, and the watch strap is used to fix the watch body 121 on the corresponding upper limb force monitoring part of the postoperative rehabilitation patient. Optionally, the watch strap includes a first watch strap 1212 and a second watch strap 1213. One end of the first watch strap 1212 is rotatably connected with the watch body 121, the other end is provided with a fixing buckle 1214 for accommodating the second watch strap 1213, and a plurality of through holes 1215 are uniformly arranged in the length direction of the first watch strap 1212. Correspondingly, one end of the second watch strap 1213 is rotatably connected with the watch body 121, and the other end is perpendicularly provided with a clamping column 1216. After passing through the fixing buckle 1214, the clamping column 1216 can be fixed on the first watch strap 1212 by pressing into the through hole 1215 and through the friction force. In another embodiment, the first watch strap 1212 and the second watch strap 1213 can also be fixed by using a hook-and-loop fastener or a bandage, which is not limited in this embodiment, as long as the watch strap can be detachably fixed on the monitoring part.

[0048] For example, Figure 2 A schematic diagram of the thin film pressure sensor 110 of the postoperative upper limb excessive force warning device is shown. As shown in the figure, Figure 2 The thin film pressure sensor 110 is a thin film pressure sensor 110 with waterproof and pressure-sensitive functions. For example, the thin film pressure sensor 110 has a multi-layer structure, which includes a waterproof layer 1101, a sensor body 1102 and a sensor gasket layer 1103. The sensor body 1102 can be a flexible thin film pressure sensor 110, and the flexible thin film can better fit the monitoring part (such as the arm). When the arm is forced, the muscle structure of the arm changes, the sensor body 1102 senses the external pressure, the sensor resistance value changes, and the resistance signal caused by the pressure change is transmitted to the processing module 1220 after being amplified by the AO-RES amplification adjustment potentiometer 1222, and the processing module 1220 converts the resistance change into a voltage value change, and then compares the voltage value change with the voltage threshold to determine whether an alarm signal occurs.

[0049] In some embodiments, the waterproof layer 1101 can also be made of any one of the following materials: a polycarbonate film, a polyurethane film, a silicone film, a polytetrafluoroethylene (PTFE) film, an ethylene-vinyl acetate (EVA) film, a polyamide film (nylon film), and a polyvinyl chloride (PVC) film. The user can select a suitable waterproof layer 1101 material according to the actual application requirements and environmental conditions. In this embodiment, the waterproof layer 1101 comprises a polycarbonate film waterproof layer 1101.

[0050] It should be understood that, in this embodiment, the sensor gasket layer 1103 is located between the sensor body 1102 and the monitored surface to enhance the effective contact between the arm measurement point and the film pressure sensor 110, ensuring the accuracy of the measurement and the performance of the sensor. By providing uniform contact pressure, the sensor gasket can effectively reduce the influence of air gaps or other surface irregularities on the measurement results. In some embodiments, the sensor gasket layer 1103 can be made of any one of the following materials: rubber, polyurethane, and silicone. In this embodiment, the sensor gasket layer 1103 can be a medical silicone layer, which has excellent biocompatibility and does not cause skin allergies or discomfort, making it suitable for long-term contact with the skin.

[0051] It is worth mentioning that the film pressure sensor 110 also comprises an adhesive layer (not shown in the figure). The adhesive layer is located on the side of the waterproof layer 1101 away from the sensor body 1102, and is used to fix the film pressure sensor 110 on the surface body 121 or an elastic sleeve (not shown in the figure). In this way, in combination with the long tail interface 1100, the monitoring point configuration of the film pressure sensor 110 can be diversified. Alternatively, the adhesive layer can be double-sided tape, which is not strictly limited in this embodiment as long as it can fix the film pressure sensor 110.

[0052] Figure 3 A structural schematic diagram of the circuit board 122 of the postoperative upper limb excessive force warning device is shown. As shown in Figure 3 The circuit board 122 is provided with a mounting circular hole 1225 for mounting the circuit board 122. As an example, a fastener (not shown in the figure) can be used to fix the circuit board 122 in the bracelet surface body 121 through the mounting circular hole 1225. Alternatively, the fastener can be a fastening bolt. In another embodiment, the fastener can also be a clasp, and the type of fastener is not strictly limited in this embodiment.

[0053] In one embodiment, the warning device further comprises a power module, which, for example, comprises a VCC power positive pin 1227 and a GND power negative pin 1228. The power pins (VCC and GND) of the power module are connected to a battery (not shown) to provide operating power for the entire warning device. It is worth mentioning that a PWR-LED (Power LED) power indicator 1226 is installed on the circuit board to indicate power-on. The main function of the PWR-LED is to indicate whether the circuit board or device is powered on. For example, when the power supply is normal, the PWR-LED will light up to indicate that the device has been powered on and is in working condition. If the PWR-LED light is off, it may indicate that the device has no power supply. Alternatively, the battery as the power supply can be a rechargeable lithium battery.

[0054] It should be understood that the processing module 1220 is the nerve center and command center of the warning device. The processing module 1220 can generate operation control signals according to instruction operation codes and timing signals to complete the control of instruction fetching and instruction execution. The processing module 1220 can also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processing module 1220 is a cache memory. This memory can save instructions or data that the processing module 1220 has just used or repeatedly uses. In this embodiment, the processing module 1220 can be used to store the pressure data obtained by the thin film pressure sensor 110 and send the pressure data to the display screen 1211 for display. In addition, the processing module 1220 receives the pressure data signal sent by the sensor body 1102 through the input interface 1221, converts the signal into a high-low level signal DO, which can be output through the interface 1229. The high-low level signal DO is a digital signal output through the interface 1229, indicating whether the pressure signal exceeds a certain threshold value, for example, a high level indicates that the pressure exceeds the preset value, and a low level indicates that it does not. The processing module 1220 can also convert the signal into an analog voltage signal AO, which can be output through the interface 1230. The analog voltage signal AO can provide a continuous value of the pressure, which is transmitted to the display screen 1211 for display, so that the patient can observe the pressure of the monitoring part of the sensor body 1102 at any time through the display screen 1211.

[0055] The following refers to Figures 1 to 3 The use of the postoperative upper limb excessive force warning device according to the present embodiment will be described in detail. It includes the following steps.
