Trinamic’s Wide Range of Precision Products Help Meet the Increased Demand for Medical Devices

An infusion pump is a medical device that delivers fluids, such as nutrients and medications, into a patient's body in controlled amounts and at specific times. Fluids can be administered intravenously, although subcutaneous, arterial and epidural infusions are occasionally used. Infusion pumps are in widespread use in clinical settings such as hospitals, nursing homes, and in the home. FDA, February 2016.

The global infusion pumps and accessories market is expected to reach USD 10.2 Billion by 2020 at a CAGR of 5.8%. Growth in this market is mainly attributed to the increasing prevalence of chronic diseases owing to the rising geriatric population; increasing use of infusion products in home care with favorable reimbursement coverage; and technological improvements in infusion products. However, the stringent product approval process and occurrence of several cases of medication errors associated with infusion pumps (and related product recalls in the recent past) may restrain the growth of the infusion pumps and accessories market during the forecast period. Trinamic product innovations focusing on improving the safety features of infusion pumps are at the center of the R&D efforts of leading players in this market.

All medical pumps are typically close to the patient’s head, so noise is always an issue. Trinamic addresses this with its proprietary stealthChop™ technology, that eliminates all noise generated by magnetostriction in the audible range.

In critical care units there are often batteries of pumps, mounted to a single stand, each dispensing a different precision medication. There is a limit to the number of pumps mounted to a single stand, so the size of the pump becomes a critical parameter. Two major variables address this demand.

The high torque available with a stepper motor compared to a dc or bldc motor allows for a small drive chain. With very efficient motor control modes like coolStep™ or closed loop operation and energy saving standby strategies Trinamics drivers reduce the total power consumption and thus the required battery size.

For one special pump type, the syringe pump Trinamic addresses an additional demand. The proprietary stallGuard™ technology allows for a very reliable and repeatable homing, while saving the cost of stop switches.
