摘要：
A device for the measurement of forces on the tip of a jet injector drug ampoule. Sensor consists of multiple spokes with strain sensing capability where each spoke has a modified linkage to allow for quasi-free bending behavior on one spoke end. By using the strain output of all three full bridges in parallel, it is possible to discriminate between lateral forces and axial forces directed collinear with the center axis of the ampoule applied to the tip of the nozzle. This information can be relayed to the user to attain, for example, a pre-determined contact force between the nozzle and an area receiving an injection.
