Document Type and Number:
Japanese Patent JP6954521
Kind Code:
B2
Abstract:
Provided is an injection apparatus which injects a dosing liquid containing a prescribed substance to an object region, the injection apparatus including: a storage unit which stores the injection liquid; a drive unit which imparts injection energy; a pressurization unit which pressurizes the injection liquid stored in the storage unit with the injection energy in the drive unit; and an injection unit which injects the injection liquid having been pressurized by the pressurization unit to the object region through an injection port. And, in a pressure transition of the injection liquid at the injection port, a vibration in the pressure transition reaches a converged state within a prescribed period of time from a rising time of pressure, and pressure reaches a peak value thereof at a prescribed rate of increase in an initial first vibration element in the vibration within the prescribed period of time, or the vibration in the prescribed period of time is a vibration at a frequency belonging to a prescribed frequency range. As a result, invasiveness to the object region during injection is reduced.
