Diaphragmatic pacemaker prototype with wireless communication

Abstract

Purpose: To describe the design and development of a diaphragmatic pacemaker prototype with wireless control, which allow the user to modify the stimulation parameters and some physiology parameters related with respiration process. Method: Begins with a bibliographic review of the main concepts of respiration and the diaphragm muscle, and a background research focused on diaphragm stimulation parameters. Followed of the design of user interface and hardware in charged of generate the pulse train with the needed specifications. Finally, the construction and coupling of the analog system with the interface, and conducting pertinent tests that allow evaluation and analysis of the device. Results: It has been made a prototype with a LabView interface and an analog system in charged of the digital to analog conversion of the information, to become the signal into a biphasic one, and a power stage, that allows to have a linear control of the current depending on the input voltage. The device had good results, beginning with and excellent transmission of the information from the user interface to generator system without data loss, in the other hand, the reception of the data and the execution of modifications is effective, with a little difference between the value entered by user and the response of the device.
