“…There are several proposals to improve the nurse call systems, for example, wiring and wireless systems [3][4][5][6][7][8]. In [4] a system that uses the RS-485 protocol is observed, it operates with the command of a button and shows visual and auditory alarms, however the wireless technology is an option that has many advantages compared to wired systems, this is why it is proposed as a future work to implement the same system through a wireless network.…”

Abstract-A nurse call system is used to improve the patient assistance and to make efficient use of the hospital staff. The aim of this project is to analyze the use of a Wireless Sensor Network (WSN) that works as an alarm center, emergency calls and as abnormal environmental parameters. The system allows knowing the temperature, relative humidity (RH) and the level of CO2, in different hospital areas, which will ease the preventive management of environmental emergencies. Moreover, the system enables to know the response time and the nurses' attention, providing statistics that will help to control the efficiency of the hospital staff and the quality level of the care provided. During the functionality testing made to the developed nurse call system, the results are encouraging, the reached data transmission reliability is 93%, from the farthest room to the nursing center. The system successfully provides relevant data to the environmental parameters of the hospital, the attention time and the staff response are successfully controlled. In the testing phase, it was also observe that the system is highly scalable, due to the easy integration of new devices to the network, thanks to the use of the ZigBee protocol and to the mesh topology. The implementation of this system is simple because it is wireless and it does not cause damage to the physical structure of the health center.

“…The technology designed for these systems is varied, although it can be classified depending on the environment of information transfer. For example, in [23] the authors proposed a wireless system for nursing calling in health centers, the equipment is designed for large health centers. The system uses a sturdy communication protocol where alarms can be installed and also uses communication by sound.…”

“…The system uses a sturdy communication protocol where alarms can be installed and also uses communication by sound. Similarly, the authors from [24] designed and implemented a wireless system for customer service, which has extra functions from [23]. For instance, the service attention command is sent in redundant mode to the nursing station and the mobile phone of the duty officer is sent by a text message.…”

“…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.…”

Design and implementation of a wired intercommunication prototype for hospital care

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.
