Diseño e implementación de un sistema de instrumentación y medida para la atención hospitalaria

Abstract

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.

Design and implementation of a wired intercommunication prototype for hospital care

“…However, it has technical issues associated to the electrical demand and the loss of data packets related to the range and consumption of the antenna. The work from [5] is simple and cheap, however, it does not have scalability as they did not define a communication protocol for data management. Therefore, it is unlikely the system can develop over time.…”

“…The system aims to send the data towards the display module with light indicator by using an asynchronous serial communication protocol. It should be noted that this approach combines elements presented in [5], [9]. First, the modularity, because the design considers several elements by hardware that are coupled by means of a communication protocol.…”

“…This device attempts to a quick patient attention; however, this solution has visualization issues that generate an inadequate alert for the medical staff. In addition, the nursing care request models between the patient and the assistance personnel do not involve the general public (family members, friends, among others) [5]. There are some cases that use cloud technology to generate reports and turn changing, but this solution brings new issues such as channels limitation and high costs, among other things [6]- [8].…”

“…In [5], [9] the authors introduced a variant that shows an alternative model for hospital care commu-nication which includes other actors related to the patients (family and friends). Although they proved a prototype's technical validation, it has bounds, for example, high energy consumption and significant loss of data packets, which affect the equipment's functionality.…”

“…This approach used the advantage of the communication protocol RS-485 for data transmission and reception. The approach retains the simplicity and some elements of the methodologies presented in [5], [9], [23], [24]. However, this approach highlights the flexibility, scalability and reliability of the equipment from a software and hardware strategy.…”
