摘要:
[Problem] Provided is a liquid administration device with which it is possible to improve operability while securing safety by providing a cover member that covers a needle tube in a manner in which the needle tube can be exposed, and to resume administration even if the administration operation is suspended in the middle of the administration. [Means for Resolution] Provided is a liquid administration device 10 including: an operation unit 20; a structure 40 which includes a syringe 60 and a needle tube 66; a cover member 30 movable between a protection position at which the needle tube 66 is covered, and an exposure position from which the needle tube is exposed; a second coil spring 11 which biases the cover member 30 in a distal direction; an exposure restriction unit E which restricts movement of the cover member 30 to the exposure position when the movement amount of the cover member 30, which moves from the exposure position to the protection position, with respect to the structure 40 reaches a predetermined exposure restriction operation amount; and a movement amount restriction unit 95 which restricts the movement amount of the cover member 30 such that the movement amount of the cover member 30 with respect to the structure 40 does not reach the exposure restriction operation amount until the movement amount of the operation unit 20 with respect to the structure 40 reaches a predetermined movement amount for completion of the administration.
