Designing a simple, modular vital monitoring system that would maximise patient comfort and provide a more efficient information management system for the hospital.


Vital signs monitoring systems for patients are disparate pieces of equipment which together consists of  anywhere between 10 to 40 components, some of which need to be plugged and unplugged depending on the patient, the procedure, the criticality of the situation and where the patient is to be moved - usage changes in the Operation Theatre, emergency room, intensive care unit and the ward.

IcarusNova spotted an opportunity to de-complicate this system by designing a modular, seamless, efficient and effective patient monitoring system that could integrate data collection and analysis.


Intense interactions with surgeons, physicians, nurses and hospital administrators were part of the re-design process. We were able to understand the problems experienced by these three stakeholders due to interrupted monitoring -loss of vital data during transit for the doctor; nurses inconvenienced by the cumbersome process of plugging and unplugging at every location; and raised anxiety and distress for the patient due to the existing monitor’s intimidating appearance.



The 'Design to Discover' phase led to the first important decision – to keep the monitoring components separate from the display. This further developed into ‘modules that travel with the patient’ with only the displays at the various stations. These modules—the main monitor, the expansion rack, the transport monitor and the thin client—are lightweight, interchangeable and store critical data.

When a patient moves from one station to the other, only the modules that need to be monitored further are unplugged and taken along with the patient. This is then re-plugged into the monitor at the new location.


The engineering phase was intensely iterative and in close collaboration with the clients technical teams as this complex project involved close to 100 moulded components.

One big challenge was to see the product through the mandatory testing phase for the various certification requirements. 25 complete sets were produced using soft tooling techniques and field trials and other mandatory tests performed on them. Feedback from this phase helped revise and baseline the design before final production was initiated.
