The present invention is also related to a system and a method for monitoring a plurality of vital health parameters of patients through sensors in a device that is wearable by the patients and providing contextual alerts and information to a plurality of stakeholders.

B) BACKGROUND OF THE INVENTION
[0002] The patients in hospitals, nursing homes or health care facilities do not always receive the right attention when the ratio of healthcare personnel to patients is low, especially in times of high-patient-occupancy. Patient attendants or caregivers have a tough time getting the attention of nurses or doctors, typically during wee hours, to attend to the patient in case of emergencies or otherwise. This is also a result of the fact that doctors do not have any automated medium to monitor the vitals of their patients.
[0003] Currently, patients' families at home or in a different part of a hospital do not know what is going on with the patient, they too have to depend on the doctors or other medical professional for updates on progress of patient health and treatment. This puts enormous pressure on the time and resources available at the hospital. Though currently digital patient beds are available with monitors and other medical apparatus attached, they are a recent phenomenon and there are no systems in place to monitor the health of patients in conventional hospital beds.
[0004] Hence, there exists a need for a real-time system and a method for monitoring the health of patients and provide alerts to a plurality of users including caregivers, nurses, doctors and family members of the patient. There also exists a need for a system and a method for monitoring a plurality of vital health parameters of patients through sensors in a device that is wearable by the patients.
[0005] The above mentioned shortcomings, disadvantages and problems are addressed herein, which will be understood by reading and studying the following specification.

C) OBJECT OF THE INVENTION
[0006] The primary object of the present invention is to provide a system and a method for monitoring the health of patients in real-time using a plurality of sensors and provide alerts to locally and remotely located users.
[0007] Another object of the present invention is to provide a system and a method for monitoring a plurality of vital health parameters of patients through sensors in a device that is wearable by the patients and providing contextual alerts and information to a plurality of stakeholders.
[0008] Yet another object of the present invention is to provide reliable monitoring of a patient’s health by reducing false alarms and improving diagnostics through a plurality of sensors embedded in a device that is wearable by a patient or situated in the proximity of the patient.
[0009] Yet another object of the present invention is to provide a system and a method that utilizes Artificial Intelligence for prediction of health risks to a patient by analyzing the data obtained by sensors monitoring the health of the patient.
[0010] Yet another object of the present invention is to provide a system and method for contextually rendering health information of a patient on a plurality of display devices.
[0011] Yet another object of the present invention is to provide a system for optimizing the power usage a plurality of devices that monitor the health of patients and provide contextual rendering of the health information.
[0012] Yet another object of the present invention is to provide a system that automatically generates reports on the health of a patient over a period and provide predictive insights on the patient’s health risks.
[0013] These and other objects and advantages of the present invention will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.
