Abstract
Abstract This novel strontium-rubidium infusion system includes means for generating a solution containing Rubidium-82, measuring the radioactivity in the solution, and infusing it into a patient in order to perform various studies on the patient's heart. The new system includes a wash syringe which can be used by a physician to manually inject a bolus containing a large amount of radioactivity directly into a patient in order to perform first pass ventriculography studies.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
67 words
A strontium-rubidium infusion system comprising: (a) means for generating rubidium-82 in a solution which can be infused into a patient; (b) means for collecting a predefined volume of solution containing rubidium-82; (c) means for measuring the radioactivity present in said predefined volume before it is infused into said patient; and (d) means for quickly infusing said predefined volume of rubidium-82 into said patient as a single bolus.
Claim 2
Dependent Claim
67 words
A strontium-rubidium infusion system comprising: (a) means for generating rubidium-82 in a solution which can be infused into a patient; (b) means for collecting a predefined volume of solution containing rubidium-82; (c) means for measuring the radioactivity present in said predefined volume before it is infused into said patient; and (d) means for quickly infusing said predefined volume of rubidium-82 into said patient as a single bolus.
Claim 3
Dependent Claim
27 words
The strontium-rubidium infusion system of Claim 1 wherein said means for generating rubidium-82 in a solution which can be infused into a patient comprises a strontium-rubidium generator.
Claim 4
Dependent Claim
22 words
The strontium-rubidium infusion system of Claim 1 or 2 wherein said means for infusing said solution into a patient comprises a syringe.
Claim 5
Dependent Claim
25 words
The strontium-rubidium infusion system of Claim 3 wherein said means for infusing said solution into a patient further comprises means for electromechanically operating said syringe.
