Abstract:
A system for correcting a patient's biological fluid containing various low-, medium- and high-molecular toxins by interaction of the biological fluid with magneto-conductive particles, the system comprising:(i) an outlet means for attaching to the patient's body for substantially continuously withdrawing therefrom the biological fluid containing the various toxins; (ii) an inlet means for attaching to the patient's body for returning corrected biological fluid back into the patient's body; (iii) an extracorporeal flow line interconnected between the outlet and inlet means for passing therethrough, in a substantially continuous flow, a predetermined amount of the biological fluid substantially not exceeding 100 ml, the flow line comprising first and second flexible tubes and a sealed vessel with a plurality of magneto-conductive particles within its bottom region, the first tube being connected between the outlet means and the particles, the second tube being connected between the inlet means and a top region of the vessel, said magneto-conductive particles being capable of absorbing the toxins in the biological fluid, whereby said predetermined amount of biological fluid becomes mixed with said magneto-conductive particles to obtain a mixture of the biological fluid with said particles; (iv) a magnetic mechanism comprising a magnetic field source producing a magnetic field region within a flow of said mixture for retaining said magneto-conductive particles in said region from a flow of particle-free biological fluid to be returned into the patient's body through the inlet means; and (v) a pump assembly that provides the biological fluid flow through the flow line with a predetermined speed value.
