[0001] The present invention relates to a system for ambulatory health monitoring real-time patient data transmission from ambulance to hospital, enabling timely medical preparation. The system also ensures efficient, interference-free communication for multiple health devices over a shared channel, optimizing critical information flow.

BACKGROUND OF THE INVENTION

[0002] The health monitoring systems utilize wearable devices to continuously track patients' health metrics outside traditional clinical settings. These systems are particularly beneficial for managing chronic conditions such as hypertension and heart disease, as they provide real-time data that enhances diagnosis and treatment efficacy. Technologies like ECG monitors and blood pressure cuffs allow for remote monitoring, improving patient comfort and compliance. Additionally, the integration of AI in these systems enables more accurate data analysis, facilitating timely medical interventions. Overall, ambulatory monitoring contributes to personalized healthcare and better health outcomes.

[0003] Traditional methods, such as focus groups and randomized controlled trials, often face significant limitations. Focus groups may lack diversity, leading to confirmation bias and skewed insights that do not represent broader populations. Additionally, traditional research methods can be inflexible, potentially failing to engage participants effectively in community settings, which may hinder the assessment of health promotion interventions. These limitations can compromise the validity and applicability of findings, necessitating the exploration of alternative methodologies.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0018] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0019] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to a system for ambulatory health monitoring real-time patient data transmission from ambulance to hospital, enabling quicker medical preparation and treatment. The system also focuses on accurate processing of health data at the hospital, improving diagnostics and patient care for better outcomes.

[0021] Referring to Figure 1, a block diagram depicting workflow of a system for ambulatory health monitoring. The ambulatory health monitoring system enables real-time collection and transmission of patient health data during transport to a hospital. The system comprises health monitoring modules, a wireless communication module, a Reflecting Surface (IRS), a Non-Orthogonal Multiple Access (NOMA) module, and a hospital receiver.

[0022] The health monitoring modules are installed in an ambulance and include devices such as electrocardiogram (ECG) monitors, blood pressure cuffs, and oxygen saturation sensors. These devices continuously collect vital signs, such as heart rate, blood pressure, and oxygen levels, from the patient. The collected data is aggregated by a central processing unit in the ambulance, which prepares it for transmission. These are medical devices like ECG monitors, blood pressure cuffs, and oxygen saturation sensors. They measure patient vital signs (heart rate, blood pressure, oxygen levels) and send the data to a central unit in the ambulance for processing.

[0023] The wireless communication module uses standard protocols, such as 5G or Wi-Fi, to transmit the aggregated health data to a hospital. This module uses 5G or Wi-Fi to send health data from the ambulance to the hospital. It connects to the central unit and transmits data over a wireless network. To ensure reliable connectivity in challenging environments like rural areas, urban settings with tall buildings, or tunnels, the system employs Reflecting Surfaces (IRS). The IRS consists of passive reflecting elements that redirect wireless signals toward the ambulance, improving signal strength and coverage. These surfaces are mounted on infrastructure such as walls, buildings, or lamp posts. A application-defined system controls the IRS, adjusting the phase and amplitude of reflected signals to optimize their direction and strength based on the ambulance’s location and environmental conditions. The IRS has passive elements that reflect wireless signals toward the ambulance. A application system adjusts how these elements reflect signals to maintain a strong connection, especially in areas with weak signals.

[0024] To address bandwidth limitations, the system includes a Non-Orthogonal Multiple Access (NOMA) module. This module allows multiple health monitoring devices to transmit data on the same frequency by assigning different power levels to each device. Using superposition coding, the NOMA module combines the signals from multiple devices into a single transmission. At the hospital, the receiver decodes these signals by distinguishing their power levels, ensuring efficient use of bandwidth and minimizing delays in data delivery. This module lets multiple devices send data on the same frequency by giving each device a different power level. It combines the signals using superposition coding, allowing efficient use of bandwidth.

[0025] The hospital receiver processes the incoming data from the wireless communication module. It separates the superimposed signals from the NOMA module and converts the data into a format suitable for medical use. This allows healthcare professionals to monitor the patient’s condition in real time, enabling timely preparation for treatment upon the patient’s arrival. The receiver collects the transmitted data, separates the combined signals based on power levels, and processes the data into a format doctors can use to monitor the patient

[0026] The system ensures continuous and reliable transmission of critical health data, overcoming challenges posed by poor signal coverage and limited bandwidth. By integrating IRS for enhanced signal direction and NOMA for efficient frequency use, the system provides robust connectivity in diverse environments, improving patient outcomes during emergency transport.

[0027] The present invention work best in the manner, where the health monitoring modules, including electrocardiogram (ECG) monitors, blood pressure cuffs, and oxygen saturation sensors, continuously gather vital signs such as heart rate, blood pressure, and oxygen levels. This data is aggregated by the central processing unit in the ambulance and prepared for transmission via the wireless communication module, which utilizes protocols like 5G or Wi-Fi. To enhance signal strength and coverage, especially in challenging environments, the system employs Reflecting Surfaces (IRS) that redirect wireless signals toward the ambulance. Additionally, the Non-Orthogonal Multiple Access (NOMA) module allows multiple health monitoring devices to transmit data simultaneously on the same frequency by assigning different power levels, thus optimizing bandwidth usage. At the hospital, the receiver processes the incoming data, separates the superimposed signals from the NOMA module, and converts the information into the usable format for healthcare professionals. This innovative system ensures continuous and reliable transmission of critical health data, significantly improving patient outcomes during emergency transport by overcoming challenges related to poor signal coverage and limited bandwidth.
