LIQUID INJECTION DEVICE |
摘要 |
A liquid injection device especially suited for injecting liquid medicine into the human or animal body. The liquid injection device (10) comprises a casing (13) having a chamber (12) into which liquid is filled, a moving body (14) constituting a part of a wall of the chamber (12) and adapted to reciprocate relative to the casing (13) so as to increase or reduce the volume of the chamber (12), a cylinder (21) integrally connected either to the casing (13) or to the moving body (14), and a piston (22) axially slidably and tightly mounted on the cylinder (21), wherein an injection port (15) and a discharge port (16) both communicating with the chamber (12) are formed in the casing (13) and an enclosed cylinder chamber (23) formed by moving the piston (22) in a direction in which it moves away from the cylinder (21) is kept in a vacuum state, and wherein the moving body (14) and piston (22) are interlocked with a interlocking means (25) such that the volume of the chamber (12) is reduced in proportion to a reduction in the volume of the cylinder chamber (23).
