Technical Field

[0001] This utility model relates to the field of medical testing products technology, specifically a wireless connection device for electrode pads. Background Technology

[0002] In the field of clinical medical monitoring, the real-time and accurate acquisition of bioelectrical signals (such as electrocardiogram (ECG) and electroencephalogram (EEG) signals) is a core technological support for disease diagnosis, dynamic monitoring of disease progression, and postoperative rehabilitation assessment. Currently, mainstream clinical bioelectrical signal monitoring systems generally adopt a wired connection architecture of "electrode pads-leads-medical equipment": disposable or reusable electrode pads are attached to specific monitoring sites such as the chest and head, and are directly connected to medical equipment such as ECG monitors and EEG analyzers via dedicated signal transmission leads.

[0003] However, existing wired bioelectrical signal monitoring solutions still have many technical bottlenecks and clinical pain points: wired connections severely restrict patients' freedom of movement, and the wires between the electrode pads and medical devices are easily pulled or tangled when patients turn over or move their limbs. This not only exacerbates the patient's discomfort during monitoring but may also cause problems such as electrode pad detachment and poor wire contact, resulting in signal acquisition interruption and affecting the continuity of disease monitoring.

[0021] This application provides a wireless connection device for electrode pads. This device, utilizing a receiver and converter, enables patients to undergo unobtrusive monitoring, increasing freedom of movement, ensuring continuous monitoring, and adapting to diverse clinical monitoring scenarios. Furthermore, the device is reusable, and when used with single-use electrode pads, it avoids the risk of disease transmission associated with reusable electrode pads, while also reducing consumable costs, thus meeting the needs of medical safety and economy. The following provides a detailed description of this wireless connection device for electrode pads. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figure 1-5 This embodiment provides a wireless connection device for electrode pads, comprising: a receiver 100, with multiple latches 110 on its top and contacts 111 inside each latch; a placement platform 120, with multiple placement platforms 120 on the surface of the receiver 100, the number of placement platforms 120 corresponding to the number of latches 110; a converter 200, disposed inside the placement platform 120, for connecting the electrode pads to convert signals; and a receiving circuit 130, disposed inside the receiver 100, for connecting to the converter 200 to receive signals.

[0024] First, establish a connection between the receiver 100 and the traditional medical device: connect the medical device wires originally connected to the traditional electrode pads to the contacts 111 inside the top mounting plate 110 of the receiver 100, thus completing the physical and signal path construction between the receiver and the traditional medical device. Take the converter 200 out from the placement platform 120 on the surface of the receiver 100, and attach the bottom of the converter 200 to the surface of the traditional disposable electrode pad, ensuring stable contact between the converter and the electrode pad. After the traditional disposable electrode pad is attached to the human monitoring area such as the chest, the electrode pad collects bioelectric signals such as electrocardiogram and electroencephalogram. The converter 200 reads the signal through its own structure. After processing the read signal, the converter 200 transmits it wirelessly to the receiving circuit 130 inside the receiver 100. After receiving and processing the wireless signal, the receiving circuit 130 transmits the signal to the connected traditional medical device through the contacts 111 of the mounting plate 110, thus completing the signal link of "electrode pad → converter → receiver → traditional medical device" and realizing the wireless conversion of the traditional medical device.

[0025] Breaking away from the traditional wired binding of medical devices and electrode pads: Through the structure of "removable converter for single use + receiver for transfer", no large-scale modification of traditional medical devices is required. Wireless signal reading can be achieved solely through this device, reducing equipment upgrade costs and balancing hygiene and economy: Traditional electrode pads can be used once, avoiding the risk of disease transmission caused by reusing electrode pads; the converter 200 can be removed from the placement table 120 and reused, reducing consumable costs and meeting the hygiene and cost control requirements of medical scenarios.

[0026] The converter 200 includes: a contact 210 located at the bottom of the converter 200 for attaching to an electrode and receiving signals; an LED bead 240 located at the top of the converter 200; and a conversion circuit 220 located inside the converter 200, which is electrically connected to the contact 210 and the LED bead 240 respectively.

[0027] After the converter 200 is removed from the placement platform 120, its bottom contact 210 is directly attached to the signal output area of ​​a traditional disposable electrode pad. After the contact 210 contacts the electrode pad, it reads the bioelectric signal collected by the electrode pad in real time. The contact 210 transmits the read signal to the conversion circuit 220 inside the converter 200. The conversion circuit 220 performs preliminary signal processing. While processing the signal, the conversion circuit 220 controls the LED bead 240 on top through electrical connection: if the contact 210 reads the signal normally and the conversion circuit 220 works normally, the LED bead 240 can display the normal working state, such as being constantly lit; if the signal is interrupted or the circuit fails, the LED bead 240 can display the abnormal state, such as flashing, providing visual feedback. The signal processed by the conversion circuit 220 is wirelessly transmitted to the receiving circuit 130 of the receiver 100, completing the wireless transmission of the signal from the electrode pad to the receiver.

[0028] The converter 200 has a patch 230 on its edge. The patch 230 is a circular sheet structure and is made of flexible material. When the converter 200 is attached to a traditional disposable electrode sheet, the circular sheet patch 230 on its edge surrounds the outer periphery of the contact sheet 210 and is attached to the surface of the electrode sheet. Since the patch 230 is made of flexible material, it can adapt to the shape of the electrode sheet, such as a circular or square traditional electrode sheet and the curvature of human skin, and fit tightly to the electrode sheet and the skin surface. This helps to fix the position of the converter 200 and prevents the converter from shifting off the electrode sheet when the human body moves.

[0029] The conversion circuit 220 contains at least a signal amplifier, a filter, a wireless transmission chip, and a power supply.

[0030] The power supply inside the converter 200 powers the conversion circuit 220, ensuring the continuous operation of components such as the signal amplifier, filter, and wireless transmission chip. The bioelectrical signals from traditional electrode pads read by the contact 210 are usually weak and contain interference. They are first transmitted to the signal amplifier, which amplifies the signal strength to a processable range. The amplified signal enters the filter, which filters out irrelevant signals such as environmental electromagnetic interference and other physiological noises from the human body, purifying the bioelectrical signal. The purified signal is transmitted to the wireless transmission chip, which encodes the signal into a wireless signal such as Bluetooth or a proprietary protocol, and sends it to the receiving circuit 130 of the receiver 100.

[0031] The receiving circuit 130 internally includes at least a signal receiving module, a signal decoding module, a signal processing module, and a DAC conversion module, and the signal receiving module is signal-connected to the wireless transmission chip. The signal receiving module in the receiving circuit 130 captures the wireless signal sent by the wireless transmission chip of the converter 200 in real time and establishes a stable wireless link. The signal receiving module transmits the received wireless signal to the signal decoding module, which demodulates and decodes the wireless signal, converting it into digital data packets that the receiving circuit can recognize. The digital data packets are transmitted to the signal processing module, which optimizes the data packets according to preset programs such as data format adaptation and error correction to ensure that the data meets the signal requirements of traditional medical devices. The processed digital signal is transmitted to the DAC conversion module, which converts the digital signal into an analog electrical signal that traditional medical devices can recognize. Finally, the analog electrical signal is transmitted to the connected traditional medical device through the contact 111 of the receiver 100 and the socket 110, completing the "wireless signal → analog signal" conversion and realizing the wireless conversion of traditional devices.

[0032] The receiver 100 has antennas 131 on both sides of its top. The antennas 131 are connected to the signal receiving module. When the wireless transmission chip of the converter 200 sends a wireless signal, the antennas 131 on both sides of the top of the receiver 100 actively capture the wireless signal in the air to expand the signal reception range. The antennas 131 transmit the captured wireless signal to the signal receiving module of the receiving circuit 130 to provide a stronger and more stable signal source for the signal receiving module, avoiding signal attenuation caused by slight obstructions between the converter and the receiver, such as clothing, human limbs, or a slightly longer distance.
