Background: Measuring and monitoring the physiological constants of patients in a hospital environment is very important in order to detect any clinical deterioration early. The use of an electronic monitor is essential for this monitoring. Objective: This study aims to describe the design and manufacturing of a new monitor called LIKITA CARE(by the company YAYI MAKE from Niger. Methodology: The LIKITA CARE( device includes two main parts: The electronic part and the software part. The electronic part includes three electronic modules: the control and signal processing module, the communication module and the power supply module. These different parts were manufactured and assembled. Results: LIKITA CARE(is a monitor for measuring the physiological constants of patients in particular: body temperature, heart rate, respiratory rate, blood pressure, electrocardiogram and oxygen saturation. It also allows you to monitor one or more patients thanks to its wifi connectivity and its web platform interface. Conclusion: LIKITA CARE(is a patient diagnostic and monitoring monitor, easy to handle and reproduce locally using 3D printing. The device allows six physiological parameters to be measured simultaneously. It would be important to compare its performance to other monitors.
