ResumenLa comunicación entre pacientes y el personal médico es una tarea imprescindible para el buen funcionamiento de hospitales y/o clínicas. Para ello, los centros de salud cuentan con intercomunicadores (pequeña central telefónica), estos equipos cumplen con una variedad de funciones que permiten potencializar la comunicación dentro de los centros hospitalarios. Sin embargo, la solicitud de servicio por parte del paciente debe estar disponible al público en general con el propósito de mejorar la calidad del servicio. En este documento se describe un sistema de instrumentación y medida que permite informar al público en general, que habitación solicita el servicio a la enfermería en un hospital. El sistema utiliza una central telefónica que envía las llamadas a un microcontrolador, el cual, procesa la información para finalmente mostrarla en un indicador luminoso (display). El sistema posee ventajas como sencillez, fácil instalación, bajo costo, que lo hacen adaptable a aplicaciones similares.

AbstractCommunication between patients and medical staff is essential for the proper functioning of hospitals and clinics task. To do this, health centers have intercoms (small telephone exchange), these teams meet a variety of functions to potentiate the communication between the patient and nurse in hospitals. However, the service request by the patient must be available to the general public in order to improve the quality of service. In this paper an instrumentation system and as to inform the general public described, which requested room service to nursing in a hospital. The system uses a telephone system that sends calls to a microcontroller, which processes the information to finally show it on an LED (Display). The system has advantages such as simplicity, easy installation, low cost, making it suitable for similar applications.

<p>The enhancement reached in the telecommunication field, especially in cellular communications, has led to the emergence of multiple multimedia services. The easy supported by the mobile networks together with their novelty has triggered their popularization among society, being considered already essential in the daily life. Likewise, the increasingly connectivity dependence of these services leads to have a huge impact of the network on the user’s perception, being their adequate provision one of the biggest concerns among telcos. Moreover, data encryption used for the security and integration of network information exchanged, together with the limited access to the application data, difficulties the assessment of the service’s end-to-end (E2E) performance. In this scope, this work presents a dataset based on multiple metrics namely KQIs, which provide the E2E conditions of different services. Particularly, the dataset considers video streaming and cloud gaming (CG) services. Furthermore, a detailed description of the testbed where the dataset has been generated is given, discussing the reasoning behind the choices made for its development.</p>
In this article, it is proposed a prototype oriented to nurse-call, which allows to create and inform the request of emergency care of a patient to the public, by means of embedded devices like the Raspberry Pi and a Display Touchscreen LCD. The emergency call is carried out by means of a network of switches that activate a channel, then this signal is conditioned and processed to be transmitted by means of a serial bus RS-485, then the received message is decoded and shown on an LCD screen, finally the request information is stored in a database. Some experiments were conducted to evaluate the energy consumption, the rate of data loss, the scope, as well as tests to validate the scalability of the prototype. The results show that the proposal presents an increase in the demand of electric energy, mainly due to the characteristics of the technology used, however, the results show that the designed system allows to quantify the dynamic in the time of the nurse-call and is compatible with other similar systems.
Introduction− In health centers, communication between the medical staff and the patient is generally performed by an intercom. Some of these devices have evolved in order to simplify the duty of medical staff by introducing indicator systems that allow to report which rooms demand medical service. However, they present technical weaknesses, for example, high energy consumption or high loss of information packets. Objective− Design and build an instrumentation and a measurement prototype for hospital care that demands less energy consumption and gives a wide range of data transmission when compared to the works proposed in the literature. Methodology− In synthesis, the prototype uses a network of switches for emergency call generation. These are sent to an intercom which enables a channel. Then, the information is processed and transmitted to every visualization module through a microcontroller and an RS-485 serial communication bus. Finally, this information is decoded and displayed in a light indicator. Results− The testing protocol evaluates and compares the operation, performance and reliability of the equipment to that similar equipment in the same time window. A reading of energy consumption and loss of data packets was performed. In addition, a random experiment was carried out and the results were modeled from a Poisson stochastic process. The results showed a decrease of power consumption in a stable regime of 91% in comparison to the results mentioned in the literature. On the other hand, the equipment presented an information loss rate under 4% of average. Conclusions− The design process included a hardware and software strategy which allowed to reduce the energy consumption of the display module in a steady state and increased the equipment's reliability. Furthermore, the equipment is technically efficient, scalable and maintenance friendly.
