Abstract

A method of substituting an MRI incompatible pump for delivering fluid to a patient with an MRI compatible pump, both pumps being microprocessor controlled. The first pump operates upon administration tubing for pumping fluid from a source thereof to the patient. The method includes the steps of: providing the second pump to be substituted for the first pump; providing second tubing having a portion thereof that is operable to function with the second pump; connecting the second tubing to the administration tubing to establish an altered fluid path from the source to the patient, the altered path including portions of both the administration and second tubing; placing the second pump for operation upon the second tubing to enable the second pump to pump the fluid through the altered path according to programming thereof; and disconnecting the first pump from the administration tubing before bringing the patient into the MRI environment.

Claims

1. A method of temporarily substituting a first microprocessor controlled infusion pump for delivering fluid to a patient with a second microprocessor controlled infusion pump, the first microprocessor controlled infusion pump being incompatible for use within a magnetic resonance imaging (MRI) environment and being for operating upon an administration tubing set for the purpose of pumping the fluid therethrough according to programming thereof, the administration tubing set being in fluid communication with a source of injection fluid and the patient, the method comprising the steps of:

(a) providing the second microprocessor controlled infusion pump to be temporarily substituted for the first microprocessor controlled infusion pump, the second microprocessor controlled infusion pump being compatible for use within the MRI environment;

(b) providing a second tubing set having at least one portion thereof that is operable to function with the second microprocessor controlled infusion pump;

(c) connecting the second tubing set to the administration tubing set to establish an altered fluid path from the source of injection fluid to the patient, the altered fluid path including at least portions of both the administration tubing set and the second tubing set;

(d) placing the second microprocessor controlled infusion pump for operation upon the at least one portion of the second tubing set for the purpose of enabling the second microprocessor controlled infusion pump to pump the injection fluid therethrough according to programming thereof; and

(e) disconnecting the first microprocessor controlled infusion pump from the administration tubing set before bringing the patient into the MRI environment wherein the patient may be subjected to at least one of imaging and spectroscopy procedures.

2. The method of claim 1 further comprising the step of priming the altered fluid path using at least one of the first microprocessor controlled infusion pump and the second microprocessor controlled infusion pump.

3. The method of claim 1 further comprising the step of, after disconnecting the first microprocessor controlled infusion pump from the administration tubing set, pumping the injection fluid through the altered fluid path and into the patient using the second microprocessor controlled infusion pump according to the programming thereof.

4. The method of claim 1 wherein the step of connecting the second tubing set to the administration tubing set to establish the altered fluid path includes connecting the second tubing set in series with the administration tubing set.

5. A method of temporarily substituting a first microprocessor controlled infusion pump for delivering fluid to a patient with a second microprocessor controlled infusion pump, the first microprocessor controlled infusion pump being incompatible for use within a magnetic resonance imaging (MRI) environment and being for operating upon an administration tubing set for the purpose of pumping the fluid therethrough according to programming thereof, the administration tubing set being in fluid communication with a source of injection fluid and the patient, the method comprising the steps of:

(a) providing the second microprocessor controlled infusion pump to be temporarily substituted for the first microprocessor controlled infusion pump, the second microprocessor controlled infusion pump being compatible for use within the MRI environment;

(b) providing a second tubing set having at least one portion thereof that is operable to function with the second microprocessor controlled infusion pump;

(c) after permitting the first microprocessor controlled infusion pump to operate upon the administration tubing set and thus pump the fluid therethrough and into the patient, stopping the first microprocessor controlled infusion pump from operating upon the administration tubing set and thus stopping the flow of the fluid into the patient;

(d) connecting the second tubing set to the administration tubing set to establish an altered fluid path from the source of injection fluid to the patient, the altered fluid path including at least portions of both the administration tubing set and the second tubing set;

(e) placing the second microprocessor controlled infusion pump upon the at least one portion of the second tubing set for the purpose of enabling the second microprocessor controlled infusion pump to operate thereon and thus pump the injection fluid therethrough;

(f) disconnecting the first microprocessor controlled infusion pump from the administration tubing set before bringing the patient into the MRI environment wherein the patient may be subjected to at least one of imaging and spectroscopy procedures;

(g) after disconnecting the first microprocessor controlled infusion pump from the administration tubing set, activating the second microprocessor controlled infusion pump so that according to programming thereof the second microprocessor controlled infusion pump operates upon the second tubing set so as to cause the pumping of the injection fluid through the altered fluid path and into the patient; and

(h) while the patient is in the MRI environment, continuing as necessary use of the second microprocessor controlled infusion pump to pump the fluid into the patient.

6. The method of claim 5 wherein the step of stopping the first microprocessor controlled infusion pump from operating upon the administration tubing set and thus stopping the flow of the fluid into the patient may also include the use of a clamp being placed upon the administration tubing set.

7. The method of claim 5 further comprising the additional step of, after performance of steps (d) and (e) but before performance of before steps (f) and (g), priming the altered fluid path using at least one of the first microprocessor controlled infusion pump and the second microprocessor controlled infusion.

8. The method of claim 5 further comprising the additional step of, after performance of steps (d), (e) and (f) but before performance of before step (g), priming the altered fluid path using the second microprocessor controlled infusion.
