FLUID INFUSION DEVICE AND DRIVING MECHANISM THEREFOR

WIPO Patent Application WO/2019/052110

A1

Disclosed is a driving mechanism (1, 1') for a fluid infusion device, the driving mechanism comprising: a shape memory driving member (11, 11') configured to generate a driving force by means of shape changes; a transmission component (12, 12'), the transmission component (12, 12') having a stress dispersion portion (121, 121'), and the stress dispersion portion (121, 121') being in contact with part of the shape memory driving member (11, 11') so as to disperse the stress on the part of the shape memory driving member (11, 11') during the transferal of the driving force; and an output component (13, 13') cooperating with the transmission component (12, 12') for outputting the driving force to a fluid pushing mechanism (2) of the fluid infusion device. The driving mechanism (1, 1') can prevent the small-radius bending of the shape memory driving member (11, 11'), such that the fatigue lifetime of the shape memory driving member (11, 11') is improved, and the overall service life of the driving mechanism (1, 1') is prolonged.
