Blunt Needle Safe Drug Delivery System

Abstract

A drug delivery device is provided having a non-luer connection and an adapter and a mating connector for providing the non-luer connection to the drug delivery device. An exemplary drug delivery device for use with a catheter connection includes a blunt needle member (110) with a non-luer connection (120) and a filter member (140) with a non-luer connection (160), wherein , the non-luer connections (120, 160) of the blunt needle member and filter member are not compatible with standard luer fittings and IV access devices.

Description

technical field [0001] Aspects of the invention relate to drug delivery systems and methods of using drug delivery systems that prevent drug delivery to an incorrect route. Background technique [0002] Drug delivery devices typically share common ISO standard luer connections, including intravascular, anesthesia, and enteral delivery devices. These pathways can be misconnected and will lead to medication errors. The consequences of such an oversight can be adverse or even fatal. [0003] Previous attempts to reduce drug delivery errors have included the use of labels or color-coded devices to distinguish specialized access devices (eg, catheter connectors) from drug-containing devices or containers used to hold drugs (eg, syringe barrels). Research has shown that clinicians tend to ignore these labels and color coding. [0004] Additionally, the number of components that must be connected and disconnected in some drug delivery systems can be time consuming and lead to co...

AI Technical Summary

Problems solved by technology

[0005] Other attempts to eliminate misrouted medication errors have incorporated check valves into one or more components, however, check valves often require complex actuation mechanisms that lead to poor functional reliability

Additionally, such devices incorporating check valves are dependent on air and / or fluid pressure, and thus, variations in flow rates, component dimensions, material dimensional stability, or surface tension can cause the check valve to fail

Additionally, check valves are typically made of rubber, which can be difficult to machine and generally cost more than plastic

Assembly of the check valve within the dispense connector can be complex and may require manual assembly

Additionally, the complex construction of devices incorporating check valves can potentially lead to infection due to the large surface area, moving parts, and parts made of different materials that can lead to bacterial growth
