Patent Images
1. An apparatus for administering a neuromuscular blocking agent to a patient to induce paralysis, said apparatus comprising:
- means for pumping a neuromuscular blocking agent to a patient;
means for controlling the operation of said means for pumping, including manual controls for manually setting the preliminary desired operation of said pumping means and further including means for entering the desired results of patient electro-stimulation test; and
means for periodically entering the actual results of patient electro-stimulation tests;
wherein said means for controlling alters the operation of said pumping means when said actual results differ from said desired results.

Abstract
A semi-automatic infusion system for administration of neuromuscular agents and the like includes a microcomputer-controlled infusion pump with a data input pad. A clinician enters the desired paralysis level and performs periodically an electro-stimulation test to determine the actual paralysis level of the patient. This information is also entered in to the system by the physician which then calculates and administers a new dosage.

5. An apparatus for administering a neuromuscular blocking agent into a patient to induce a selectable level of paralysis, said apparatus comprising:
-
infusion pump means for infusing said agent to said patient; microprocessor means coupled to said infusion pump means for controlling the operation thereof; data input means coupled to said microprocessor means for entering a first signal indicative of a desired paralysis level and a second signal indicative of the actual paralysis level of said patient based on a preselected test; and memory means for storing a program for said microprocessor corresponding to said agent and said test, responsive to which program, said microprocessor determines the operation of said infusion pump. - View Dependent Claims (6, 7, 8, 9, 10)

11. A method of administering a neuromuscular blocking agent for inducing a preselectable level of paralysis on a patient comprising the steps of:
-
providing an infusion pump system for infusing said patient; microprocessor means coupled to said infusion pump system for controlling the operation thereof; data input means coupled to said microprocessor; entering in said data input means a predetermined level of paralysis; monitoring said patient to determine his actual level of paralysis; entering said actual level in said data input means; and adjusting the infusion of said agent to said patient in accordance with the difference between said actual and predetermined level of paralysis. - View Dependent Claims (12, 13, 14, 15)
