SYRINGE
Document Type and Number:
Japanese Patent JP2015226578
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a syringe which shortens a time until an injection rate is stabilized, and can reduce waviness of a flow rate due to changes in the injection rate.SOLUTION: A syringe comprises: an outer cylinder 2 for storing a fluid therein; a piston 3 which is slidably fitted in an axial direction on the inside of the outer cylinder, and sucks or discharges the fluid into the outer cylinder; a plunger 4 which is movable in the axial direction inside the outer cylinder, has a force transmission part 41 at one end, which is in contact with a base end contact part 31 of the piston 3 and transmits force thereto, and is configured to move integrally with the piston 3; and a gasket 5 which keeps a space between the inner peripheral surface of the outer cylinder 2 and the piston 3 air-tightly and fluid-tightly.
