Description

Technical Field

[0001] This utility model relates to the field of medical monitoring equipment, specifically a postoperative electrocardiogram monitoring electrode pad with temperature monitoring. Background Technology

[0002] In modern medical monitoring, electrocardiogram (ECG) monitoring electrodes are widely used to acquire patients' ECG signals, especially in postoperative monitoring, intensive care, and daily physiological parameter monitoring, where ECG signals are an important indicator for assessing cardiac health. An existing ECG electrode and monitoring device (publication number: CN213406051U) has the following drawbacks and requires further improvement.

[0003] Traditional ECG monitoring electrodes typically only have the function of acquiring ECG signals, while body temperature measurement usually requires additional independent equipment. These independent temperature measuring devices require manual measurement by medical staff, making it difficult to achieve continuous, real-time temperature monitoring. This is especially true for postoperative patients, as frequent temperature measurement operations may increase the nursing burden, affect patient comfort, and may lead to discontinuity or delay in temperature monitoring.

[0004] In current medical monitoring protocols, electrocardiogram (ECG) monitoring and temperature monitoring devices are typically separate. This not only increases equipment costs and hospital resource consumption but also affects doctors' assessment of patients' conditions due to data asynchrony between the devices. Therefore, current technology still lacks an electrode pad that integrates ECG and temperature monitoring functions to meet the needs of postoperative monitoring. Utility Model Content

[0005] The main objective of this invention is to provide a postoperative electrocardiogram monitoring electrode with temperature monitoring, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a postoperative electrocardiogram (ECG) monitoring electrode pad with temperature monitoring, wherein an electronic component layer is provided at the bottom of the protective breathable layer, an electrode conductive layer is provided below the electronic component layer, an outer layer is provided below the electrode conductive layer, a flexible circuit board is provided inside the electronic component layer, a signal processing circuit module is welded on the flexible circuit board, a WiFi module is welded on the flexible circuit board, an ECG electrode is welded on the flexible circuit board, the processing circuit module, the WiFi module, and the ECG electrode are electrically connected, four bolt holes are provided around the flexible circuit board, and four circuit board bolts are installed in the four bolt holes respectively, and a temperature sensor is provided inside the electrode conductive layer.

[0007] Preferably, the protective breathable layer is made of medical-grade polyurethane membrane nonwoven material, and the edge of the protective breathable layer extends and covers the periphery of the electronic component layer to form a sealed structure.

[0008] Preferably, the flexible circuit board is fixed using surface mount technology. The four corners of the flexible circuit board are provided with through holes with a diameter between 1.8mm and 2.2mm. The edges of the through holes are provided with metal reinforcing rings. The four circuit board bolts pass through these through holes, pass through the electronic component layer, and are tightened with the pre-set threaded holes on the electronic component layer.

[0009] Preferably, the outer layer is made of medical-grade pressure-sensitive adhesive material, and its edges are sealed to the electrode conductive layer by high-frequency welding to form a continuous adhesive structure, with the outer layer edges extending outward by 2-4 mm.

[0010] Preferably, the WiFi module and the signal processing circuit module are connected by a flexible FPC cable with a diameter of 0.15mm-0.25mm. The cable has a 4-layer structure and is coated with an EMI shielding layer. The WiFi module is fixed to the flexible circuit board by 6 solder joints, each with a diameter of 0.3mm-0.5mm.

[0011] Preferably, the temperature sensor is embedded in the electrode conductive layer and bonded to the bottom surface of the electrode conductive layer with medical-grade double-sided thermally conductive adhesive. The thermal conductivity of the thermally conductive adhesive is between 2.0 W / m·K and 3.5 W / m·K. The temperature sensor and the signal processing circuit module are connected by silver-plated wires with a diameter of 0.12 mm to 0.3 mm, and the outer layer of the wires is coated with an insulating high-temperature resistant coating.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating a temperature sensor into the postoperative ECG monitoring electrodes, ECG signals and body temperature data can be simultaneously acquired on the same device, enabling continuous, real-time temperature monitoring and avoiding the manual operation required by traditional standalone temperature measurement devices. The temperature sensor is embedded in the conductive layer of the electrode, making direct contact with the patient's skin. A signal processing circuit module converts the temperature signal into data, which is then transmitted synchronously to the monitoring device along with the ECG signal.

[0014] This device incorporates a flexible circuit board, a WiFi module, and a signal processing circuit module, enabling wireless transmission of ECG signals and temperature data to the monitoring system. This avoids the problem of traditional ECG and temperature monitoring devices operating independently. The electronic component layer provides encapsulation and fixation for the circuitry, while the circuit board bolts ensure the structural stability of the electrode pads, preventing components from loosening or shifting.

Below the electronic component layer 2 is an electrode conductive layer 3. Below the electrode conductive layer 3 is an outer layer 4. A flexible circuit board 5 is provided inside the electronic component layer 2. A signal processing circuit module 6 is soldered above the flexible circuit board 5. A WiFi module 7 is soldered above the flexible circuit board 5. An ECG electrode 8 is soldered above the flexible circuit board 5.

Four bolt holes are provided around the flexible circuit board 5, and four circuit board bolts 9 are installed in the four bolt holes respectively. A temperature sensor 10 is provided inside the electrode conductive layer 3.

[0024] The protective breathable layer is made of medical-grade polyurethane membrane nonwoven fabric, offering excellent breathability and comfort, reducing friction with the skin and allowing the skin to breathe. At the bottom of the protective breathable layer is an electronic component layer, primarily used to support the flexible circuit board and other electronic components. The edges of the protective breathable layer extend outwards and cover the perimeter of the electronic component layer to form a sealed structure. This ensures that the internal components are protected from external contamination and enhances the overall stability of the electrode pads.

[0025] A flexible circuit board is embedded within the electronic component layer. This circuit board, fixed using surface mount technology, provides a bridge for connection between various electrical components. The signal processing circuit module, mounted on the flexible circuit board, is responsible for amplifying, filtering, and processing the acquired signals. Through meticulous design, the signal processing circuit module on the flexible circuit board can stably process analog signals from the ECG electrodes and temperature sensor, converting them into digital signals.

[0026] The conductive electrode layer, located beneath the electronic component layer, is designed to directly contact the patient's skin to collect electrocardiogram (ECG) signals. Made of conductive material, this layer is integrated with the ECG electrodes to ensure effective acquisition of weak electrical signals from the heart. A temperature sensor is embedded within the conductive electrode layer and bonded to its bottom surface using medical-grade double-sided thermally conductive adhesive. This sensor directly contacts the skin, monitoring body surface temperature in real time. This design ensures a tight bond between the temperature sensor and the ECG electrodes, guaranteeing synchronized signal acquisition.

[0027] The WiFi module is connected to the signal processing circuit module via a flexible circuit board. Its function is to wirelessly transmit ECG signals and body temperature data to an external monitoring system in real time. This system can receive data wirelessly and display the patient's ECG waveform and body temperature changes on a real-time monitoring device, providing doctors with continuous monitoring data.

[0028] The outer layer is made of medical-grade pressure-sensitive adhesive material, which serves to fix the electrode conductive layer and other internal electronic components in the proper position. The outer layer is sealed to the electrode conductive layer by high-frequency welding, ensuring that the device will not loosen or shift during use, thus increasing the stability and safety of the product.

[0029] The ECG electrodes are connected to the flexible circuit board by soldering. Four bolt holes are located around the flexible circuit board; the board bolts are tightened through these holes and into pre-threaded holes on the electronic component layer, ensuring the stability of the assembly during use.
