Abstract
Liquid infusion apparatus includes non-magnetic materials in a pumping structure and drive motor therefor, and in a controller that supplies drive signals to the motor to facilitate convenient operation in intense magnetic fields without distorting the magnetic fields and without radiating objectionable radio-frequency interference. A non-MRI-compatible liquid infusion apparatus is temporarily replaced with MRI-compatible, non-magnetic liquid infusion apparatus without disconnecting patient from an installed intravenous infusion set to continue infusing liquid within the MRI environment.
Claims6
A method of temporarily replacing with a secondary pump a primary liquid-infusing pump coupled through a primary intravenous (IV) injection set between a liquid source and a patient while preserving the patient's connection to the primary IV set, the method comprising:
- connecting the patient to the primary IV set;
- infusing liquid into the patient though the primary IV set and the primary pump;
- inhibiting fluid flow through the primary pump;
- connecting a secondary IV set to the primary IV set at locations upstream and downstream of the primary pump;
- and
- infusing liquid into the patient through the connection thereof to the primary IV set and through the secondary pump and secondary IV set.
