Wireless Hospital Patient Emergency Nurse Call-Up System

ABSTRACT

Much difficulty is experienced in hospitals and nursing homes with the proper response to calls for nurses by patients and also to matters of security. Various systems are employed, sometimes in a rather haphazard or makeshift manner, for calling nurses to the rooms of patients. Most frequently, each patient has in ready reach near the bed a push button switch which sounds a buzzer or lights a call light at some nursing station. There is usually no provision to keep the buzzer sounding periodically until the call is answered or to keep the indicator light on until the light is answered or to extinguish the light when the call is answered. Many calls from patients go unanswered and frequently time is wasted by making a second response to the patients call.

This work discusses a simple hospital room call bell circuit which can be installed in hospital patient rooms for allowing the patients to get a quick access to a medical representative or a nurse whenever in need, by simply pressing a call button at the bedside.

 CHAPTER ONE

1.1                                                        INTRODUCTION

During the recent decade, rapid advancements in healthcare services and low cost wireless communication have greatly assisted in coping with the problem of fewer medical facilities. The integration of mobile communications with wearable sensors has facilitated the shift of healthcare services from clinic-centric to patient-centric and is termed as “Telemedicine” in the literature. In the larger perspective, telemedicine can be of two types: (1) live communication type, where the presence of the doctor and patient is necessary with additional requirements of high bandwidth and good data speed, and (2) store and forward type, which requires acquisition of medical parameters such as vital signs, images, videos, and transmission of patients data to concerned specialist in hospital.

Wireless hospital patient emergency nurse call-up system is a device found around a hospital bed that allows patients in health care settings to alert a nurse or other health care staff member remotely of their need for help. When the button is pressed, a signal alerts staff at the nurse’s station wirelessly, and usually, a nurse or nurse assistant responds to such a call. Some systems also allow the patient to speak directly to the staffer; others simply beep or buzz at the station, requiring a staffer to actually visit the patient’s room to determine the patient’s needs.

1.2                                         SIGNIFICANCE OF THE PROJECT

Wireless hospital patient emergency nurse call-up system provides the following benefits to patients:

• Enables a patient who is confined to bed and has no other way of communicating with staff to alert a nurse of the need for any type of assistance
• Enables a patient who is able to get out of bed, but for whom this may be hazardous, exhausting, or otherwise difficult to alert a nurse of the need for any type of assistance
• Provides the patient an increased sense of security

The call button can also be used by a health care staff member already with the patient to call for another when such assistance is needed, or by visitors to call for help on behalf of the patient.

1.3                                             OBJECTIVE OF THE PROJECT

The aim of this project is to send messages or an alert during emergency situations especially when a patient is alone at hospital to a medical personnel when emergency needed the attention of a nurse or doctor. When the button is pressed, a signal alerts staff at the nurse’s station wirelessly, and usually, a nurse or nurse assistant responds to such a call.

1.4                                           LIMITATION OF THE PROJECT

• Some patients develop the habit of overusing a call button. This can lead staff to frustration, alarm fatigue, up to and including ignoring or disregarding the patient’s calls or not taking them very seriously. “Alarm fatigue” refers to the response – or lack of it – of nurses to more than a dozen types of alarms that can sound hundreds of times a day – and many of those calls are false alarms. Staff cannot ignore such calls, as doing so violates the law in most places. Sometimes, mental health professionals will work with such patients in order to curtail their use of the button to serious need.
• The sensors are costly
• If power supply fails, the circuit will not work.

1.5                                          APPLICATION OF THE PROJECT

It is found around a hospital bed that allows patients in health care settings to alert a nurse or other health care staff member remotely of their need for help. The newer applications also provide education, test and medication reminder alerts, and a means of communication between the patient and the provider.

It can be operated remotely by interfacing aØ GSM modem system. It can be used in ICU’s , operation theaters,Ø monitoring of oxygen levels etc. It can be also used in old age homes to monitorØ the various parameters of a sick person in old age homes.
