Abstract: When using a drug container having an identification tag fixed or detachably provided at a predetermined position of the container, the tag having drug data on a kind and a concentration of a drug and both or one of upper and lower limits of a flow rate on a continuous infusion and the upper and lower limits, time and flow rate on a one-shot administration recorded thereon, it is possible to ensure safety by prompting for a stop of injection by a warning when a setting beyond the upper and lower limits is performed and rewrite a liquid infusing time and a flow rate and so on required to be set according to symptoms of a patient.

Abstract: A syringe pump adapted to inject a liquid medicine in the syringe according to a predetermined infusion pattern, comprising a syringe diameter detecting means for detecting the volume of the syringe, an infusion pattern input means for inputting an infusion pattern, an occlusion pressure setting means, a pusher position calculating means, and a drive control means for drive-controlling a motor on the basis of an inputted infusion pattern to push the pusher of the syringe so as to infuse the liquid medicine in the syringe, and characterized in that the pusher position is calculated on the basis of the set-inputted infusion pattern and the occlusion detection level is automatically changed according to the pusher position.
