摘要： An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

摘要： A piezoelectric vibrator that includes a piezoelectric resonator, a substrate having opposite first and second principal surfaces, and an electrically conductive holding member holding the piezoelectric resonator on the first principal surface of the substrate such that the piezoelectric resonator is able to be excited. The electrically conductive holding member contains a first filler containing an electrically conductive material as a main component and a second filler containing an electrically insulating material as a main component and having a smaller Young's modulus than the first filler. In a plan view in a direction normal to the first principal surface of the substrate, the second filler is more densely disposed in an outer peripheral region of the electrically conductive holding member than in a central region of the electrically conductive holding member.
