ABSTRACT:
A liquid metering and injecting device has a reservoir (10), a pump means (11) and a delivery tube (13) in fluid communication. A motor (19) of the pump means (11) is controllably operated so that a plunger (18) is reciprocated within a cylinder (17). A valve means (32) directs the flow of liquid from the reservoir (10) to the pump means (11) as the plunger (18) is retracted and from the pump means (11) to the delivery tube (13) as the plunger is extended without backflow. With this construction, a selected amount of liquid (14) is periodically metered and injected to a patient.
