Abstract:
1. An automated strontium-rubidium infusion system comprising: a first three-way valve comprising a first port, a second port, and a third port, and a second three-way valve comprising a first port, a second port, and a third port; a syringe pump and an eluent container connected to to the syringe pump via the first port of the first valve and the second port of the first valve; a strontium-rubidium generator comprising a generator's input and generator's output, a first filter coupled to the generator's input and a first pressure sensor coupled to the generator's input; means for infusing eluate into a patient, the means for infusing coupled to a second filter and a second pressure sensor for controlling pressure of the eluate infused into the patient; a control and operating unit connected to a computer and to a third three-way valve comprising a first port, a second port, and a third port and to a fourth three-way valve comprising a first port, a second port, and a third port; a first air bubbles detector connected to the control and operating unit and disposed along a pipe between the eluent container and the first port of the first valve; a second air bubbles detector connected to the control and operating unit and disposed along a pipe between the third port of the fourth valve and the third port of the second valve; and means for measuring radioactivity; wherein the second port of the second valve is connected to a waste receptacle, the first port of the second valve is connected via the pipes and via the second filter to the eluate infusion means, the first port of the third valve is connected via the pipes to the third port of the first valve, the second port of the third valve is connected via the pipes to the input of the generator, the generator's output is connected to the first port of the fourth valve, the third port of the third valve and the second port of the fourth valve are connected with a pipe; wherein if an amount of strontium-rubidium in the eluate to be delivered to the patient has been generated, or if the first bubble detector detects an air bubble, then the control and operating unit generates a control signal to the third and fourth valves and the eluate bypasses the strontium-rubidium generator; wherein if the first air bubble detector or the second bubble detector detects an air bubble, then the control and operating unit generates a control signal to the second valve and the eluent solution or the salt solution is removed to the waste receptacle, and wherein if the first bubble detector is activated, the eluent solution is removed to the waste receptacle bypassing the generator.
