Device for detection of a change of pressure in a canal of a microdosing device

To detect pressure changes in the fluid flow path (2) of a micro-dosing unit, i.e. an insulin pump (1), an emitter (4) and a sensor (5) in the housing (20) register a bulge at the membrane (7) in a body (3), indicating a blockage in the flow path causing a shift in the pressure. The body can be chan...

Zusammenfassung:To detect pressure changes in the fluid flow path (2) of a micro-dosing unit, i.e. an insulin pump (1), an emitter (4) and a sensor (5) in the housing (20) register a bulge at the membrane (7) in a body (3), indicating a blockage in the flow path causing a shift in the pressure. The body can be changed once or a number of times while the sensor and emitter remain.
