Johnson Electric introduces miniature medication dosing system technology

Johnson Electric today announced a miniature medication dosing system technology under the Johnson Medtech brand.  The subsystem platform provides a high precision dosing accuracy over device operational life.  The Johnson Medtech system design delivers dosing forces up to 100N for various medication viscosities within a compact package.  The low noise and low power consumption of the dosing system is suitable for the smallest portable medication delivery devices.

This innovative design includes a precise leadscrew driven by a miniature geared motor, a displacement sensor, an optical sensor and an optional force sensor.  The multiple sensors system design can prevent inaccurate dosing and supports fail-safe features for dosing.

"Accuracy is critical in medication dosing for patients with diabetes or growth hormone deficiency," said Jim Dick , Johnson Electric's senior vice president of Strategic Marketing.  "The Johnson Medtech technology enables precision dosing in miniature packages," he added.
