Blunt needle safety drug delivery system

Abstract

Drug delivery devices having non-luer connections and adapters and adaption connectors for providing non-luer connections to drug delivery devices are provided. An exemplary drug delivery device for use with a catheter connection includes a blunt needle component (110) with a non-luer connection (120) and a filter component (140) with a non-luer connection (160), wherein the non-luer connections (120, 160) of the blunt needle component and filter component are incompatible with standard luer fitting and intravenous route-accessing devices.

Description

[0001] This case is a divisional case of a Chinese invention patent application with the international application number PCT / US2011 / 045281, the international application date is July 26, 2011, the invention name is "Blunt Needle Safety Drug Delivery System", and the Chinese national phase application number is 201180045315.2 Apply. technical field [0002] 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 [0003] 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. [0004] Previous attempts to reduce drug delivery failures have included the use of labels or color-coded devices to distinguish specialized access devices (eg, cat...

AI Technical Summary

Problems solved by technology

[0006] 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
