Automated Luer Lock Connection with Radial Loading and Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical fluid connection systems, particularly Luer lock connections, require manual operation and can cause mechanical stress on patients during cannulation, risking vessel damage and requiring secure but complex connection procedures.
Innovation Solution
An automated apparatus with rotatable and displaceable receiving devices allows for radial introduction of connecting elements, enabling simple and secure production and disengagement of fluid flow-capable medical threaded connections, including Luer lock connections, using a control device and sensor systems for precise torque and force control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual Luer lock connection is used, then the connection can be established, but mechanical stress is applied to the patient's blood vessel during cannulation
Solution Approach 1:
The system performs self-alignment and self-connection of the Luer lock components through automated receiving devices that guide and secure the connecting elements without requiring manual manipulation, thereby eliminating mechanical stress on the patient's blood vessel while ensuring reliable connection
Solution Approach 2:
The manual mechanical connection process is replaced by an automated apparatus that uses controlled receiving devices to establish the Luer lock connection, substituting the harmful manual mechanical stress with a controlled automated system that protects the blood vessel
2Productivity
If automated apparatus is used, then connection efficiency is improved, but device complexity increases
Solution Approach 1:
The automated apparatus is divided into distinct functional modules including a first receiving device for the male connector and a second receiving device for the female connector, each with specific functions for alignment and securing, allowing the complex automation task to be managed through modular components
Solution Approach 2:
The receiving devices are designed to perform multiple functions: guiding the connecting elements into proper alignment, securing them during the connection process, and maintaining the Luer lock engagement, thereby reducing the need for additional separate components and managing device complexity

AI summary
An apparatus is provided for producing and/or disengaging a fluid flow-capable medical threaded connection. The connection can be a Luer lock connection. The apparatus includes a first receiving device for receiving a first connecting element, and a second receiving device for receiving a second connecting element. The first receiving device and the second receiving device are rotatable relative to each other about a common screwing axis, and displaceable relative to each other along the screwing axis. The apparatus is designed to relatively move the first receiving device and the second receiving device toward and away from each other such that the first connecting element and the second connecting element can be screwed together or disengaged. An associated connecting element can be introduced into the first receiving device and/or into the second receiving device, in a radial direction relative to the screwing axis. A method is also provided.
