[0002] In modern medical monitoring, bedside medical equipment such as monitors, anesthesia machines, and ventilators play a crucial role. These devices can monitor patients' vital signs in real time, providing doctors with accurate medical data to assist in diagnosis, treatment, and surgery. With the development of medical technology, numerous medical devices from different manufacturers have emerged on the market.

[0032] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1 and attached Figure 8The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.
[0033] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.
[0034] like Figure 1 As shown, a smart device data acquisition gateway includes:
[0035] The main control unit, including but not limited to one or more processors, memory units and operating systems, is used to perform data logic processing, protocol conversion, data caching and user interface management;
[0036] The data acquisition interface unit is used to exchange data with different types of bedside medical devices and transmit medical data to the main control unit for processing.
[0037] The data transmission unit is used to transmit the data collected by the main control unit to the data platform via wired and / or wireless means.
[0038] The human-machine interface unit communicates with the main control unit via a bus to display system status, device data information, and the user interface in real time; and
[0039] The power supply unit is used to convert AC power into DC voltage suitable for system use.
[0040] In the above description, the data acquisition interface unit includes an Ethernet interface, an RS232 interface, and an interface multiplexing circuit. The Ethernet interface and the RS232 interface are connected to the bedside medical device via the multiplexing circuit. Specifically, the multiplexing circuit includes a network transformer and an RJ45 interface. Four pins of the RJ45 interface are used for RS232 interface signal transmission, and the remaining four pins of the RJ45 interface are connected to the output of the network transformer. The input of the network transformer is connected to the Ethernet interface. Figure 2 As shown, L2 is the network transformer, RJ1.1 is the RJ45 interface, and C28 and C30 are the center tap capacitors of the network transformer. The signal is isolated by the network transformer and then output to the RJ45 interface. The center tap of the network transformer output is grounded through resistor R15, which can make the DC bias voltage of the output signal 0V, providing a reference level for the RS232 interface signal. The four lines of the RS232 signal use the four unused lines of the 100Mbps Ethernet as outputs, thus realizing the multiplexing of the RS232 interface and the Ethernet interface, that is, the same RJ45 interface can be used to connect to bedside medical equipment.
[0041] Furthermore, in the specific implementation process, such as Figure 3As shown, the Ethernet interface uses the CH390H chip U1, which connects to the main control unit via the SPI interface. C16, C17, and C20 are decoupling capacitors required by the chip, and X1 is a 25MHz passive crystal oscillator required for Ethernet operation, directly connected to the CH390H chip. Figure 4 As shown, the RS232 interface uses the SP3232 chip U2, which is responsible for converting TTL serial port levels to RS232 standard levels. C33 is a power supply decoupling capacitor, and C34, C35, C36, and C37 are bootstrap capacitors required for the SP3232 to operate. The RS232 level interface is connected to ground in parallel with transient suppression diodes D1, D2, D3, and D4, consisting of four lines: RX (one transmit, one receive), CTS (one transmit), and RTS (one receive, one transmit).
[0042] To improve the integration of the data acquisition gateway, this embodiment adopts an integrated design for the main control unit and the data transmission unit, specifically using the Espressif ESP32-S3-WROOM-1U-N16R8 wireless module. Figure 5 As shown, it incorporates an ESP32S3 MCU chip as the main control unit, and also includes a wireless module and a storage module, supporting WiFi 802.11b / g / n and Bluetooth 5.0. The ESP32S3 chip's CPU is... The 32-bit LX7 dual-core processor, with a clock speed of 240MHz, provides ample performance for data processing and protocol conversion.
[0043] In the above, the main control unit also includes a clock module for system time management and timed data acquisition. Specifically, as shown... Figure 6 As shown, the clock module uses the DS3231 clock chip, which has a built-in clock crystal and temperature sensor, eliminating the need for clock calibration. The DS3231 chip is connected to a CR1220 button battery B1, which can maintain its high-precision clock even when the system is powered off, ensuring that the data collected from the bedside medical device has a clear acquisition time.
[0044] To ensure the normal operation of the data acquisition gateway, the power supply unit includes a step-down module. The input of the step-down module is connected to the mains power, and the output of the step-down module is connected to the +3.3V power supply port. For example... Figure 7As shown, an external 220V AC mains power supply is connected through a fence-type terminal block U5, and a power output is simultaneously connected in parallel to power the bedside medical device. The AC mains power consists of a live wire, a neutral wire, and a ground wire. A fuse F1 is connected to the live wire, and a varistor R4 and a safety capacitor C4 are connected in parallel with the neutral wire. Then, a step-down chip U6 is connected to step down the voltage to obtain a 3.3V DC power supply. This 3.3V power supply is then connected in parallel with filter capacitors C6, C9, and C10 for power stabilization. This direct connection method prevents the bedside medical device from malfunctioning due to a faulty data acquisition gateway, ensuring uninterrupted monitoring of user medical data.
[0045] like Figure 8 As shown, the human-machine interface unit includes an LCD screen and a screen interface circuit. The screen interface circuit includes a MOSFET Q1. The source of MOSFET Q1 is connected to a resistor R1, one end of a capacitor C1, and a +3.3V power supply port. The other end of capacitor C1 is grounded. The gate of MOSFET Q1 is connected to the other end of resistor R1 and the PWM output terminal of the main control unit. The drain of MOSFET Q1 is connected to the driving terminal of the LCD screen through a resistor R3. The LCD screen is a 1.54-inch LCD from Zhongjingyuan, connected via an FPC1 connector, and communicates with the ESP32S3 main control MCU chip using an SPI interface. MOSFET Q1, as the driving element of the LCD screen, is responsible for controlling the backlight or pixel drive of the screen to ensure clear image display. In specific use, the ESP32S3 main control MCU chip outputs a pulse width modulation (PWM) signal to adjust the brightness of the LCD screen backlight.
[0046] In practical use, this invention utilizes an integrated data acquisition interface unit and a multiplexing circuit to enable Ethernet and RS232 interfaces to share the same RJ45 interface, establishing a connection with bedside medical equipment and acquiring medical data. The acquired data is transmitted to the built-in ESP32S3 main control MCU chip for logic processing and protocol conversion. Subsequently, the data transmission unit uses a wireless module or Ethernet interface to send the processed data to the data platform. The human-machine interaction unit displays the system status and equipment data information in real time and allows users to perform local monitoring and operation. Simultaneously, the clock module provides the system with precise timestamps to achieve timed data acquisition and synchronization.
[0047] In summary, this utility model's intelligent device data acquisition gateway, through its innovative design, provides a highly efficient, integrated, highly compatible, easy-to-deploy, user-friendly, real-time, secure, cost-effective, and easy-to-maintain solution for medical monitoring. Its integrated and simplified design reduces the number of components and production costs, while ensuring the efficient, accurate, and secure acquisition, processing, and transmission of medical device data. This gateway not only possesses excellent compatibility and user experience, but also achieves miniaturization, low cost, and high stability through interface reuse technology and innovative power supply unit design, while guaranteeing data real-time performance and security, providing an advanced, reliable, and economical solution for medical monitoring.
