Title: Wireless ECG and PULSE Sensor for Patient Health Monitoring System

Abstract: The present condition of patients in hospitals is completely keeping the patient on bed for months and years together which is making to feel the patient very uncomfortable , as they are not willing to stay but the patient condition should be monitored by the doctor whenever there is a an emergency situation. The goal of this project was to produce a wireless ECG and PULSE sensor for patient monitoring system which could allow the patients to be in the mobile environment. This will enable the doctor to observe the patient without having the physical present at bed side but they may be in hospital or at their home. This system includes a pulse sensor which measure pulse of the patient and ecg sensor to measure complete body condition of the patient.The entire kit will be connected to the patient if the patient condition reaches to the abnormal situation then an sms will be send to the doctor mobile via GSM SIM 800 module. The patient body temperature, ECG and heart rate are transferred to doctor and patient family member and to the nearest ambulance through an sms, in an abnormal situation to get an immediate treatment to the patient. The main advantage of this system is to compare the previous systems the energy consumption, speed up to increase the freedom and to enhance the patient quality of life.

Mobile Technology System Ffor Health Intervention (M Health)

Mobile Technology System Ffor Health Intervention (M Health)

A sample report of a patient is shown in Table 1. The report contains personal information about the patient along with heart rate and body temperature of the patient. The report shows a comparison between the normal values and the calculated result. According to the data calculated it can be analyzed that the same results were obtained as that of the normal values of heart rate and temperature from our system. The ECG graph is not much clear due to the noise generated by electrical components used in the project. Also another issue with the system was the efficiency of pulse rate monitor while detecting the readings from the patient. Due to the basic design of the sensors the light generated from the pulse sensor is sometimes not transmitted properly thus readings cannot be obtained easily. Also while calculating the body temperature there is a minor variation in the actual body temperature due to the presence of surroundings. Another major concern with the project is security because Bluetooth allows anyone to connect to the application and thus get information about the patient. However if the device proves to be helpful then security issues can be alleviated.

Pulse wave response characteristics for thickness and hardness of the cover layer in pulse sensors to measure radial artery pulse

Pulse wave response characteristics for thickness and hardness of the cover layer in pulse sensors to measure radial artery pulse

fracture of the sensor cells due to contact with the wrist skin. Three types of pulse sensors coated with the hardest silicone as the cover layer were fabricated with cover layer thicknesses of 0.8  mm, 1.0  mm, and 2.0  mm. The fabrication sequence of the pulse sensors with the cover layer is shown in Fig. 2. A thermistor that measures skin temperature was soldered to the patterned PCB. Six pressure sensors were arranged in-line and fixed by soldering, and the pressure sensors were then connected to the patterned PCB by wire bonding. To protect the connected wires, underfill (HI-FILL 3085B, HI-TECH KOREA CO., LTD, South Korea) was coated on the wires. Barri- ers were placed on the edges of the patterned PCB, and silicone was poured in the barriers to form the cover layer on the pulse sensor. The thickness of the cover layer was controlled by the amount of silicone. The silicone was cured by baking the pulse sensor in an oven at 150 °C for 30 min. The individual pulse sensor with the cover layer was cut out of the construct using a dicing saw. A fabricated pulse sensor with the cover layer included 1 thermistor and 6 piezo-resistive pressure sensors and measured 10  mm × 8  mm in size, as shown in Fig.  3. The 3 kinds of silicone used to make the cover layer were XE14-C2042, IVS4546, and IVS4742 (MOMENTIVE, NY, USA); their hardnesses were 43, 49, and 71 (Shore type A durometer), and their tensile strengths were 6.0  MPa, 7.1  MPa, and 11  MPa, respectively [32]. Although IVS4312 (hardness: 29 and tensile strength: 0.8  MPa) was tested, it was too sticky to be used as a cover layer for the pulse sensors. Hardness was considered in evalu- ating the dynamic response of the pulse sensors because the mechanical properties, such as Young’s modulus and Poisson’s ratio, among others, were not provided by the manufacturer. A pulse sensor with a 1-mm-thick polydimethylsiloxane (PDMS) cover layer was used as a reference sensor in the evaluation of the dynamic response of the pulse sensors. The reference pulse sensor with the PDMS cover layer was made via the standard fabrication method; PDMS has a hardness of 30. The reference sensor was used for the comparative analysis of the pulse sensors with the silicone cover lay- ers because of the difficulty in obtaining the simulator waveform.

An Intelligent Medical Monitoring System Based on Sensors and IoT

An Intelligent Medical Monitoring System Based on Sensors and IoT

MQTT is based on clients and a server. Likewise, the server is responsible for handling the client requests of receiving or sending data between each other. MQTT server is called a broker and the clients are simply the connected devices. So when a device (a client) wants to send data to the broker, we call this operation a “publish”. And when a device (a client) wants to receive data from the broker, we call this operation a”subscribe”. This client are publishing and subscribing to topics. So, the broker here is the one that handles the publishing/subscribing actions to the target topics.In this architecture, the pulse sensor, temperature sensor, ultrasonic sensor and weight sensor have to send their data to the broker. On the other side, a desktop application wants to receive these values. The broker role here is to take the data and deliver it to desktop application.

where it was found to be a rapid, reproducible, as well as a highly sensitive and specific technique for detecting small bowel ischemia. The use of commercial pulse oximeters for estimating splanchnic perfusion in humans has been found to be impractical (bulky probes, cannot be sterilized, etc). More recently a custom made reflectance pulse oximeter has shown for the first time that good quality photoplethysmographic (PPG) signals can be detected from various human abdominal organs (bowel, kidney, liver) during open labarotomy [1]. However, this probe is not suitable for prolonged continuous monitoring in the abdomen. Therefore, there remains a need for a new sensor technology that is suitable for use in the human abdomen and will allow the continuous measurement of SpO 2 in the

or less [2]. Moreover, slow reaction time of the transmittance mode PPG has also been reported in low peripheral perfusion [7]. In order to overcome some of the limitations of the commercial transmittance or reflectance pulse oximeters that appear in cases of poor PPG pulsations, a new multimode photoplethysmography processing system [6] was developed and a pilot study was conducted to assess its performance in acquiring meaningful and reliable photoplethysmographic signals [7]. The purpose of this study was to investigate in detail the threshold where pulse oximetry fails to produce accurate SpO 2 values. In order to compare the reliability of

the red and infrared AC PPG signals are sensitive to changes in arterial oxygen saturation because of differences in the light absorption of oxygenated and deoxygenated haemoglobin at these two wavelengths [10]. From the ratios of these amplitudes, and the corresponding DC photoplethysmographic components, arterial blood oxygen saturation is estimated. Hence, the technique of pulse oximetry relies on the presence of adequate peripheral arterial pulsations, which are detected as photoplethysmographic (PPG) signals [3]. The accuracy of commercially available pulse oximeters in critically ill patients has been investigated in several studies [1]. Compared with the Gold standard (multiwavelength CO oximeter) of measuring arterial oxygen saturation (SaO 2 ), the accuracy of pulse oxi-
