A fluid exchange system may include a control unit comprising a processor; a tube set attachment removably connected to the control unit, the tube set attachment comprising a tube set fluidly connected to a fluid source and a drainage receptacle; a catheter fluidly connected to the tube set; and at least one sensor positioned on at least one of the control unit and the tube set attachment, wherein the control unit may be configured to supply fluid to a patient through the tube set and drain fluid from the patient via the tube set, and wherein the control unit may be configured to receive measurements from the at least one sensor to adjust the supply of the fluid to the patient and the drainage of the fluid from the patient.

Fluid exchange system and related methods

A method of delivering a solution including at least one drug is provided. The method includes providing a fluid exchange catheter system which includes an inner lumen, the proximal end of which is connected to an infusion mechanism configured to control infusion of a solution that includes at least one drug, and an outer lumen, the proximal end of which is connected to an aspiration mechanism configured to control aspiration of fluid from the body. The method also includes activating the infusion mechanism to infuse the solution into the body for a first infusion time period and at a first infusion pressure, disabling the infusion mechanism to stop infusion, and activating the aspiration mechanism to aspirate fluid for a first aspiration time period and at a first aspiration pressure. Also described is a method of unblocking a fluid exchange catheter.

Fluid exchange catheter system

A method of infusing and aspirating fluid from the body is provided. The method includes providing a catheter system which includes an inner lumen, the proximal end of which is connected to an infusion mechanism configured to control infusion of a fluid, and an outer lumen, the proximal end of which is connected to an aspiration mechanism configured to control aspiration of fluid from the body. The method also includes activating the infusion mechanism to infuse fluid into the body for a first infusion time period and at a first infusion pressure, disabling the infusion mechanism to stop infusion, and activating the aspiration mechanism to aspirate fluid for a first aspiration time period and at a first aspiration pressure.

A catheter system that can be used for concurrent fluid infusion and aspiration in humans, animals and biological material, at a wide range of flow rates, without any blockage problems. The system has devices that control the infused liquid's pressure changes accordingly to the aspirated liquid's pressure changes, in order to allow accurate and safe fluid exchange flow control and create changes of pressures at the catheter's tip that do not allow the catheter's blockage.
