Abstract
A method for determining a backflow of a substance along a track of a delivery device includes: a) obtaining parameters that influence the flow of the fluid or substance; b) acquiring information about delivery data; and c) computing the backflow along the delivery device using the information in steps a) and b).
Claims20
A method for determining a backflow of a substance along a track of a delivery device placed within a patient, comprising:
- a) obtaining parameters that influence the flow of the substance;
- b) acquiring information about delivery data;
- c) computing, prior to infusion of the substance into the patient, the backflow along the delivery device using the information in steps a) and b);
- and
- d) using at least one of the computed backflow distance or shape to simulate further pressure fields, fluid concentration or flow parameters.
A computer program embodied on a non-transitory computer readable medium for determining a backflow of a substance along a track of a delivery device placed within a patient, comprising:
- a) code that obtains parameters that influence the flow of the substance;
- b) code that acquires information about delivery data;
- c) code that computes, prior to infusion of the substance into the patient, the backflow along the delivery device using the information in steps a) and b);
- and
- d) code that uses at least one of the computed backflow distance or shape to simulate further pressure fields, fluid concentration or flow parameters.
An apparatus for determining a backflow of a substance along a track of a delivery device placed within a patient, comprising:
- a processor and memory;
- logic stored in the memory and executable by the processor, said logic including
- a) logic that obtains parameters that influence the flow of the substance;
- b) logic that acquires information about delivery data;
- c) logic that computes, prior to infusion of the substance into the patient, the backflow along the delivery device using the information in steps a) and b);
- and
- d) logic that uses at least one of the computed backflow distance or shape to simulate further pressure fields, fluid concentration or flow parameters.
