[0002] Drug clinical trials are an important means of evaluating the safety and efficacy of new drugs, and vital sign monitoring is an important method for assessing the safety of subjects and the effectiveness of the drug. The significance and necessity of monitoring the vital signs of subjects in drug clinical trials are as follows:

[0003] Assessing drug safety: Drug clinical trials require assessing drug safety. Vital sign monitoring can promptly detect adverse reactions and side effects in subjects, such as changes in vital signs like heart rate, blood pressure, and respiration, allowing for timely intervention to ensure the safety of the subjects.

[0004] Assessing drug efficacy: Drug clinical trials require assessing drug efficacy. Vital sign monitoring can reflect the effects of drugs on the physiological functions of subjects, such as changes in vital signs like heart rate, blood pressure, and respiration, thereby assessing drug efficacy.

[0005] Improving test quality: Vital sign monitoring can improve test quality, promptly detect changes in the vital signs of subjects, take timely measures to avoid bias in test results, and improve the reliability and accuracy of the test.

[0006] Protecting the rights of research participants: Vital sign monitoring can protect the rights of research participants, promptly detect adverse reactions and side effects, and take measures to ensure the safety and health of research participants.

[0007] Therefore, monitoring the vital signs of subjects in drug clinical trials is essential to ensure their safety and health, improve the quality and reliability of the trial, and protect their rights. Based on this, we propose a digital mobile ward system for clinical trials. Summary of the Invention

The system automatically processes and stores the information, enabling it to understand the vehicle's driving status and operating environment in real time, and promptly detect the vehicle's driving status and the real-time condition of the patient inside the vehicle.

[0080] The remote video unit can provide remote experts with real-time information about the patient in the vehicle. Experts can analyze the patient's condition based on the high-definition video, arrange work through full-duplex voice intercom, and know the specific location of the medical vehicle based on BeiDou satellite positioning information.

[0081] The intelligent risk warning unit uses high-definition video and human skills to identify risk events such as being too close to the vehicle in front and posing a collision risk, changing lanes without using turn signals, and having a pedestrian in front of the vehicle and posing a collision risk. It uploads video evidence to the platform in the form of video clips to urge drivers to strictly follow regulations and drive safely, thereby improving driving safety.

[0082] The information management unit can download and query vehicle driving recorder and video files via wired / wireless network. It can also play back, transfer, and archive the vehicle's storage media on a computer for easy viewing of the vehicle's interior, route, and speed later.

[0083] Vehicle location management is used to locate vehicles, automatically save vehicle dispatch records, and access vehicle equipment data in real time.

[0084] The Medical Connect electronic medical record function enables truly integrated management of medical device data and patient electronic medical record information. The Medical Connect electronic medical record system is deeply integrated with the patient vital signs transmission system, eliminating the need to repeatedly enter relevant information into different systems and significantly reducing the workload of staff.

[0085] In addition, in this application, authorized expert users can log in to the data center receiving platform via PC / PAD / mobile phone to view the data.

[0086] This system adopts a cloud architecture, with all systems deployed on cloud servers. Alternatively, systems can be deployed on local servers depending on specific needs. Users may also purchase their own hardware, provided the purchased hardware meets the system's network requirements.

[0087] This system is based on cloud service concepts and adopts a B / S architecture for web browsing. Vehicle information can be transmitted in real time via mobile network, eliminating the need for users to purchase various hardware and software devices. Leaders and experts can log in to their accounts and view the transmitted data at will via the network. The above functions can be achieved by adding a 5G IoT transmission module and activating cloud services.

[0088] The data transmission packet loss rate is less than 1%. In the event of a network interruption, data is temporarily stored for no less than 30 minutes and can be automatically reconnected and retransmitted after the network is restored.

[0089] This system supports wired and wireless access to mainstream medical devices such as monitors, defibrillators, ventilators, and electrocardiographs, and displays them within the same system.

[0090] This system truly integrates vehicle information, patient vital signs data, electronic medical records, and on-site images / videos, displaying them within a single system. This eliminates the need to switch between different systems, significantly reducing the workload for frontline staff. It also ensures consistent data collection times across multiple medical devices, automatically parsing device protocols and filling in the collection time for each data entry, guaranteeing the accuracy and validity of the data sent to the server.

[0091] The IoT-dedicated transmission module in this system has multiple interfaces such as Ethernet, WIFI, and MAX232 / 485, which are compatible with various vehicle-mounted medical devices. It can also provide a convenient (already parsed, can be directly converted into chart format) data interface, and each function can be activated separately.
