Method and a system for administering muscle relaxant to a patient
First Claim
1. A system for administering muscle relaxant to a patient, said system including:
- an infusion pump adapted for delivering said muscle relaxant to a patient, a controller adapted for controlling the operation of said infusion pump on the basis of at least one received input value, and measuring means adapted for continuously measuring the effect of said muscle relaxant on the patient, and adapted for supplying a value representing said measured effect as said input value to said controller, wherein on basis of said at least one input value, said controller is adapted for selecting a control value from a set of predetermined control values as the value to be used for controlling said infusion pump, characterised in that said measuring means is adapted for stimulating a muscle of the patient by a number of succeeding electric or magnetic pulses, for measuring the resulting muscle reaction pulses and for using the number of muscle reaction pulses as said input value.

Abstract
The invention relates to a system for administering muscle relaxant to a patient. The system includes an infusion pump adapted for delivering said muscle relaxant to a patient, and a controller adapted for controlling the operation of said infusion pump on the basis of at least one received input value. Further the system includes measuring means adapted for continuously measuring the effect of said muscle relaxant on the patient and adapted for supplying a value representing said measured effect as said input value to said controller. According to the invention, on basis of said at least one input value, said controller is adapted for selecting a control value from a set of predetermined control values as the value to be used for controlling said infusion pump. The invention also relates to a method of administering muscle relaxant to a patient and to a testing apparatus adapted to be used for testing the automatic operation of a system for administration of muscle relaxant to a patient.

11. A method of administering muscle relaxant to a patient, said method including:
-
delivering said muscle relaxant to a patient, where delivery is controlled on the basis of at least one received input value, and continuously measuring the effect of said muscle relaxant on the patient, and supplying a value representing said measured effect as said input value for said controlling, characterised in that said controlling is performed using a set of predetermined control values and further including selecting of a control value from said set of control values as the value to be used for controlling said infusion pump, where said selection is based on said input value and/or a value derived therefrom. - View Dependent Claims (12, 13)
