Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of medical monitoring systems, and more particularly to an Internet of Things (IoT)-based automated system designed to continuously monitor the vital signs of comatose patients. [Background technology]
[0002] In traditional intensive care settings, monitoring of comatose patients is typically performed through manual monitoring—measurement of blood pressure with a sphygmomanometer, temperature with a thermometer, and visual monitoring of urine volume in a catheter bag—and the intermittent use of standalone medical devices. These methods rely heavily on nursing staff, requiring regular checks, manual recording, and prompt reporting of abnormal values to medical professionals. However, such manual systems tend to have various weaknesses, including delayed detection of critical abnormalities, inconsistent data recording, and the risk of human error. Furthermore, with increasing patient populations and a shortage of medical personnel, continuous manual tracking of vital signs is becoming impractical and unsustainable. While individual digital devices exist to measure specific parameters, they lack integration, automation, and remote access.
[0003] Therefore, there is a pressing need for an automated, integrated, IoT-enabled system that can not only collect multiple physiological parameters in real time, but also transmit them for remote monitoring and generate alerts to enable prompt medical attention. Summary of the Invention
[0004] The IoT-based vital signs monitoring system 100 is an IoT-based automated monitoring device for comatose patients. It includes a central control unit 102 connected to a blood pressure sensor 104, a temperature and humidity sensor 106, a urine volume sensor 108, and a human presence sensor 110. Data from these sensors is processed, displayed on a liquid crystal display (LCD) unit 112, and transmitted to a cloud platform 116 via a wireless communication module 114. An alarm is triggered if a value exceeds a threshold. The IoT-based vital signs monitoring system 100 is powered by a power supply unit 118 and assembled on a printed circuit board (PCB) 120, enabling real-time monitoring with reduced manual effort. [Effects of the Invention]
[0005] The IoT-based vital signs monitoring system 100 enables continuous and automatic monitoring of vital signs of comatose patients without manual review.
[0006] The IoT-based vital signs monitoring system 100 ensures real-time detection of abnormal conditions and provides instant alerts via a liquid crystal display 112 (LCD) and a cloud platform 116.
[0007] Doctors can monitor patient data remotely, leading to faster response times and improved patient outcomes.
[0008] The built-in blood pressure sensor 104, temperature and humidity sensor 106, urine volume sensor 108, and human presence sensor 110 reduce human error, lighten staff workload, and enable efficient management of multiple patients.
[0009] The IoT-based vital signs monitoring system 100 is cost-effective and easy to deploy in hospitals. [Brief explanation of the drawings]

[0011] The IoT-based vital signs monitoring system 100 is designed for continuous monitoring of comatose patients. The central controller 102 is implemented using a Raspberry Pi® and is configured to receive information from a blood pressure sensor 104, a temperature and humidity sensor 106, a urine volume sensor 108 based on ultrasound measurement, and a human presence sensor 110 based on passive infrared (PIR) detection. The blood pressure sensor 104 monitors systolic and diastolic blood pressure. The temperature and humidity sensor 106 measures body temperature and ambient humidity. The urine volume sensor 108 detects the fluid volume in the catheter bag. The human presence sensor 110 identifies body movement to detect signs of regaining consciousness.
[0012] The central controller 102 processes the data received from each sensor and transmits the analysis results to a liquid crystal display (LCD) unit 112 for patient monitoring. A wireless communication module 114 transmits the data received from each sensor to a cloud platform 116 for remote access by medical personnel. Both the liquid crystal display (LCD) unit 112 and the cloud platform 116 act as interfaces to trigger alarms when measurements exceed medical thresholds, such as abnormal blood pressure, high body temperature, a full catheter bag, or unexpected behavior.
[0013] A power supply unit 118 provides power to the IoT-based vital signs monitoring system 100. A printed circuit board (PCB) 120 integrates each sensor, the central controller 102, the liquid crystal display (LCD) unit 112, and the wireless communication module 114, as well as all electronic components including resistors, capacitors, integrated circuits, and switches. Control logic, sensor interfacing, alarm handling, and data communication are managed by Python®-based software running on a Linux® operating system installed on the central controller 102.
[0014] The IoT-based vital signs monitoring system 100 provides automated, real-time, and remote monitoring to minimize manual review, increase reliability, and improve patient safety in intensive care settings. [Industrial Applicability]
[0015] This invention is beneficial for physicians and comatose patients.
