Design of a nursing call system: an alternative

Abstract

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.

“…An example is item 'Ac4_When I call for help, then I have to wait long time'. Deitrick et al (2006) and Salcedo et al (2019) highlighted that call bells are related to patient safety and fall prevention. Hence, they recommend nurses to answer patient calls as soon as possible to assess the urgency of the call and determined whether the call should be answered immediately or if can be answered at a later time (Deitrick et al, 2006).…”
