As more and more connected devices being used in hospitals for patient monitoring, a real concern for hospitals and healthcare institutions is how to handle wireless congestion. This could lead to delay or loss in transmission of vital body signals and might lead to incorrect medical diagnosis.
Our Client, a market leader in healthcare device manufacturing in the US wanted to develop an end to end application which could transport real time data over MBAN from an ECG patch.
The Wireless ECG system consists of 3 units:
Patch is a coin cell operated wearable device which collects 4 lead ECG and Respiration from human body. Patch digitize data and transmits it over MBAN.
Receiver unit collects the data from a patch and and sends the data stream to dock over USB interface. Receiver provides user interface through onboard display and LEDs. Receiver to transmitter pairing is based on proximity.
Receiver configuration updates and firmware upgrade can be done by connecting the USB port to a PC running the utility software.
Dock receives ECG data and play out data through a conventional ECG monitor. The data is then converted to analog output using DAC which can be directly connected to ECG monitor. Respiration data is simulated to the ECG monitor using digital potentiometer controlled based on the patch respiration data.
