Abstract

PURPOSE: To suck and discharge medical liquid in an equal quantity by driving plungers of medical liquid pumps by the stroke locomotion based on the rotation of a cylindrical cam.
CONSTITUTION: When a motor 9 is started to rotate a cylindrical cam 12 at a fixed speed, in accordance with the rise and fall of each elevating rod 14, a plunger 20 in each pump main body 18 is alternately operated by mutually-different phase timing for making a suction stroke at the time of rise and a discharge stroke at the time of fall. In the suction stroke, since a negative pressure is given inside a chamber 19 in accordance with the rise of the plunger 20, medical liquid L is sucked into a valve cylinder 26 through a suction cylinder 27 of a suction valve part V1 to push up a ball valve 34, and introduced into a chamber 19. When a fixed quantity of the medical liquid L is finished to be sucked, each ball valve 34 is dropped by the weight of itself to close each valve seat 29, and simultaneously, the next discharge stroke is started. This construction permits to continue the uniform discharge of the medical liquid stably.
