Patient Monitoring System
Nurses have to routinely check temperatures , BP and patient health 4 times a day. Patients are sometimes disturbed if asleep for these routine checkups. They maintain all the records on paper and files which are tedious to maintain and access. The doctor has to go through different patient files to see and if necessary make changes in drugs and fluids dosages.The present system includes a lot of paperwork . A system was needed to monitor patients and maintain records. A lot of staff hours can thus be saved using TLC.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The TLC system composes the smart bed with an OLED screen and a TLC application which is used in a laptop or a tablet at the nurse station. The TLC smart bed is made of smart fabric which records temperature , BP, sleep pattern and moisture levels. This data is sent via radio frequency to the nurse tablet providing continuous monitoring and helps save a lot of staff hours. The patient screen is an OLED transparent screen and does not disturb the patient due to brightness .
OPERATION / FLOW / INTERACTION:
Patients can control their mattress temperatures and bed position with the intuitive GUI OLED screen without having to call the nurse. Also the screen is used by the nurse to maintain a record of drugs and fluids administered which is then sent to the interface at the nurse station. The TLC interface at the nurse station shows and alerts any changes in parameters such as patient body temperature, blood pressure, sleep pattern and moisture levels. This interface can also be assessed by the doctor to view patient history and make changes in the drug dosages.
PROJECT DURATION AND LOCATION:
MIT Institute of Design.
FITS BEST INTO CATEGORY:
Scientific Instruments, Medical Devices and Research Equipment Design
PRODUCTION / REALIZATION TECHNOLOGY:
The TLC smart bed is made using embedded chips to monitor physiological functions. Capacitive swatches are used for electrocardiogram (ECG) sensing. Fabrics incorporating thermocouples are used for sensing temperature.Shape-sensitive fabrics sense movement. Carbon electrodes integrated into fabrics can be used to detect specific environmental or biomedical features such as oxygen, salinity, moisture, or contaminants. Resistive elements woven into fabric provide active heating .
SPECIFICATIONS / TECHNICAL PROPERTIES:
Patient OLED screen-360mm width and 200 mm height.

User insight research was gathered by observing and interviewing a large number of experienced field technicians in various hospitals. Patient habits and problems were observed and recorded. Insights were gathered from bio medical engineers and doctors.
The TLC system had a challenge of developing a interface system which was simple and intuitive considering patients backgrounds and cultural habits. The OLED screen was thus designed simple with just two buttons for enabling the patients to control their mattress temperature and bed position. The nurse station interface was developed so as to be clean and simple to view all the physiological parameters and alerts for parameters going out of range.
