Embodiment Construction

[0017] The following relates to monitoring motor wear of MR compatible syringe pumps or other MR compatible devices employing non-magnetic motors. In such medical devices, non-magnetic rotary motors are used to provide the power to drive, for example, the piston that pushes the plunger of a syringe to deliver a fluid drug, or the pump membrane of a fluid pump that drives a volumetric infusion pump, among others. In the case of infusion pumps, for certain types of drugs, such as vasopressors that cause vasoconstriction to raise blood pressure, interruption of drug delivery for even a few seconds can have adverse effects on the patient's health. In syringe pumps employing common magneto motors, it is known to monitor the operation of the motor to detect malfunctions. However, such monitoring cannot predict motor failure, and thus may lead to discontinuation of critical medications.

Abstract

A rotary drive for a medical device (10) includes a rotary motor (14) including a rotor (26). A rotary motion encoder (34) is connected to the rotor. The rotary motion encoder is configured to generate a number of encoder steps measuring a rotational distance of the rotor. At least one electronic processor (18) is programmed to determine at least one of a slippage value of the rotary motor measured during motor operation and a coasting value of the rotary motor measured after stopping motor operation based on comparison of an actual count of encoder steps and an expected count of encoder steps.

Description

technical field [0001] The following generally relates to the field of radiology, the field of medical infusion, the field of infusion pumps and related fields. Background technique [0002] Currently, infusion pumps used in hospitals and homes use a system of motors to pressurize fluids for delivery to patients. These motor systems are subject to wear. These types of pumps perform a health check of the drive system at startup and allow or disable the clinician from using the pump. There is no predictive element for this decision. [0003] Infusion pumps commonly used in hospitals cannot be safely used in an MRI environment because they pose serious safety risks to clinicians and patients. Specialized pumps have been developed specifically for MR use, but these carry their own risks in that these pumps are different from the ones the clinician is familiar with and can be lost in emergency situations as the clinician struggles to perform unfamiliar maneuvers. seconds. ...
