Quality System Audits


DLMS believes that quality is one of the most important issues that any medical device manufacturer should address, so we go far above and beyond what is required by regulatory authorities.

The DLMS distribution facility in Scottsdale Arizona, which warehouses and distributes our products in North America, employs a state-of-the-art qualty management system which exceeds the standards and requirements of the Food and Drug Administration and Health Canada.   To insure the highest standards of quality, DLMS periodically hires outside independent medical device quality systems auditors to conduct formal third-party inspections and reviews of our facilities, records, systems, quality manual, procedures and records.

Our superior quality systems are also regularly reviewed by our largest customers as part of their auditing processes.
