Syringe pump, and liquid feeding method
First Claim
1. A syringe pump which infuses a liquid medicine in a syringe according to a predetermined infusing pattern comprising:
- a syringe diameter detection means which detects the capacity of the syringe, a liquid infusing pattern input means which inputs a liquid feeding pattern, an occlusion pressure setting means, a pusher position calculating means and a drive control means which controls the driving of a motor on the basis of an input liquid infusing pattern and injects the liquid medicine in the syringe by pushing the pusher of the syringe;
characterized in that a pusher position is calculated on the basis of the set and input liquid feeding pattern and that an occlusion detection level is automatically changed according to said pusher position.

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.
