Abstract
This invention relates to medical engineering, in particular, to means of automation of the process of generating a diagnostic solution from a radionuclide strontium-rubidium generator and performing of remote controlled infusion, with automatic control over the key characteristics of the process. The automated strontium-rubidium infusion system comprises a container with eluent, a strontium-rubidium generator with a filter and a pressure sensor at the input, an eluate infusion unit, which are connected by means of a transporting system provided with pipes and two three-way valves, radioactivity measuring means and a control and operating unit. Here, an eluent container is connected to a syringe pump via the first and second ports of the first three-way valve, the first port of the second three-way valve is connected with pipes via the second filter to the eluate infusion unit, and the second port is connected to a waste receptacle. The system additionally comprises the third and fourth three-way valves, the first and second air bubbles detectors are connected to the control and operating unit connected with a computer, where the third three-way valve is connected with its first and second ports via pipes to the third port of the first three-way valve and the input of the strontium-rubidium generator, respectively. The generator output is connected to the first port of the fourth three-way valve, where the third port of the third valve and the second port of the fourth valve are connected with a pipe, the first air bubbles detector is placed on the pipeline between the eluent container and the first port of the first valve, and the second air bubbles detector is placed on the pipeline between the third ports of the fourth and second valves.
