“…HBHS consists of a thermoelectric hypothermic helmet, a control unit, and a power unit. Helmet temperature is controlled by an 8-bit PIC16F877 microcontroller, which is adjusted between −5°C and +46°C with an accuracy of +/−0.5 °C [24]. Moreover, a heating rate controller is obtained using an AT89C55WD microcontroller for the measurement of thermo luminescence (TL) in alkali halides and other related compounds.…”

<p>This study reviews the evolution of smart applications of microcontroller-based wireless/wired remote monitoring systems. Rapid developments in science and technology offer the advantages of using integrated embedded chips, microprocessors, and microcontrollers. The use of microcontrollers in industrial processes, such as automobiles, aeronautics, space, robotics, electronics, defense applications, mobile communications, rail transport, and medical applications, is rapidly increasing. This study aims to review the progress of microcomputers in smart remote monitoring and controlling applications for the control and management of different systems using wireless/wired techniques</p>

“…Microcontrollers require some simple peripheral circuits when they are used for circuit designs. For example, power supply is used to supply required energy for both microcontroller and its neighboring circuits [13][14][15][16]. Power supplies must be isolated from mains and have a limited current and voltage output in order to protect the patient.…”

This article proposes the employment of a proportional valve that can calculate the amount of oxygen in the air to be given to patient in accordance with the amount of FiO which is set from the control menu of the ventilation device. To actualize this, a stepper motor-controlled proportional valve was used. Two counts of valves were employed in order to control the gases with 2 bar pressure that came from both the oxygen and medical air tanks. Oxygen and medical air manometers alongside the pressure regulators were utilized to perform this task. It is a fuzzy-logic-based controller which calculates at what rate the proportional valves will be opened and closed for FiO calculation. Fluidity and pressure of air given by the ventilation device were tested with a FlowMeter while the oxygen level was tested using the electronic lung model. The obtained results from the study revealed that stepper motor controlled proportional valve could be safely used in ventilation devices. In this article, it was indicated that fluidity and pressure control could be carried out with just two counts of proportional valve, which could be done with many solenoid valves, so this reduces the cost of ventilator, electrical power consumed by the ventilator, and the dimension of ventilator.

“…215 Human brain hypothermia system developed by the Electronics and Computer Education Department, Faculty of Technical Education Gazi University, Ankara, Turkey The system comprises 'a microcontroller-based control card, four different temperature measurement circuits, a electronic control card module, a water circulation system, a switching mode power supply, and a helmet' (p. 502). 216 The temperature range is -5 °C to 46.15 °C because it is intended that the device could also be used for hyperthermic tumour therapy. This device is undergoing animal testing and has not yet been used in humans (Dr Guler, 28 February 2011, personal communication).…”

HTA NIHR Health Technology Assessment programmeThe Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service' . The HTA programme is needs led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects. First is the commissioned route. Suggestions for research...
