In this paper, we implement a common module that can integrate multiple biometric information for integrated patient monitoring system. Conventional biomedical instruments have many devices attached to each patient, making it difficult to monitor abnormality signs of many patients in real time. In this paper, we propose a module for an integrated monitoring system that can perform centralized monitoring using a common module that integrates multiple measurement devices. A protocol for sending and receiving packets between the measuring device and the common module is designed, and the packets transmitted through the network are stored and managed through the integrated monitoring system and provide information to various users such as medical staff. The results of this study are expected to contribute to the management of patients and efficient medical services in hospitals.

This paper addressed real-time urine monitoring device for intensive care patients. The device was developed to detect and count each urine drop using optical sensor and calculate the current urine output volume and its hourly rate. In experiment, the water volume scale of drainage bottle was observed and compared with the count of the device so that the volume of each drop was found to vary with the dropping rate per minute. From this measurement, the relationship equation was derived to estimate the total water volume from the drop rate (correlation coefficient : r= 0.99). The developed device could be applied to count patient's urine drop successfully. Therefore, this device can be used to monitor intensive care patient's urine status in real-time.

A hospital room has multiple patient monitoring devices at the bedside to monitor his or her status. However, vital sign monitors, ventilator and other bedside devices are made by a variety of different manufacturers and often cannot easily interface to the hospital information system. Medical environments incorporate complex and integrated data networks to transfer vast amounts of patient information, such as images, waveforms, and other forms of digital data. Hence, to assure interoperability of images, waveforms and patient data, Health Level Seven (HL7) was developed as an international standard to facilitate the communicating and storing of medical data. In this study, we developed middleware capable of receiving data from mCare 300 vital signs monitoring devices and converting the data to HL7 data format. The HL 7 middleware streamline clinical workflow and support patients. Therefore, clinical expertise are empowered to respond to dynamic healthcare situation as soon as they emerged, and consequently quality of care while helping to reduce the length of a patient's stay in a hospital.

In order to apply the patient monitoring system to the hospital field, it is necessary to be able to measure and analysis data the major bio-signals that are basically covered by the existing patient monitoring system. We have implemented a wearable device and the patient monitoring system for measuring ECG and oxygen saturation. The implemented system transmits the measured bio-signal to the server on the nursing station via Bluetooth. It is represented by graph waveforms and numerical values that can be checked by the medical staff in the patient monitoring system. The validity of this system is verified by comparing the data collected through the designed system with the data obtained from the conventional equipment.

In this paper, we proposed the implementation of software-based 2D BitBLT engine on the pSOS operating system and the operation of the BitBLT engine on patient monitoring device was verified. To verify the proposed method on the patient monitoring device, we designed prototype PCB board, and verified the operation. We designed the motherboard by using ARM9-based CPU. Because hardware-based BitBLT module was replaced with software-based one, CPU load problem was weighted. To solve this problem, w changed 400Mhz processor instead of 200Mhz processor. We implemented 2D BitBLT kernel module as a device driver which is one of the key elements of a graphics controller GUI in patient monitoring device.

A wrist watch type wearable cardiovascular monitoring device is proposed for continuous and convenient monitoring of the patient's cardiovascular system. For comprehensive monitoring of the patient's cardiovascular system, the concurrent electrocardiogram (ECG) and arterial pulse wave (APW) sensor front-end are fabricated in $0.18{\mu}m$ CMOS technology. The ECG sensor frontend achieves 84.6-dB CMRR and $2.3-{\mu}Vrms$-input referred noise with $30-{\mu}W$ power consumption. The APW sensor front-end achieves $3.2-V/{\Omega}$ sensitivity with accurate bio-impedance measurement lesser than 1% error, consuming only $984-{\mu}W$. The ECG and APW sensor front-end is combined with power management unit, micro controller unit (MCU), display and Bluetooth transceiver so that concurrently measured ECG and APW can be transmitted into smartphone, showing patient's cardiovascular state in real time. In order to verify operation of the cardiovascular monitoring system, cardiovascular indicator is extracted from the healthy volunteer. As a result, 5.74 m/second-pulse wave velocity (PWV), 79.1 beats/minute-heart rate (HR) and positive slope of b-d peak-accelerated arterial pulse wave (AAPW) are achieved, showing the volunteer's healthy cardiovascular state.
