Needleless Connector Securement With Movable Bracket Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical fluid delivery systems lack effective primary and secondary securement mechanisms to prevent displacement and dislodgement of catheters and needleless connectors, leading to potential patient injury and contamination during extended fluid delivery, and fail to manage catheters during saline-administered workflows efficiently.
Innovation Solution
A dual securement system comprising a catheter securement device and a needleless connector securement device, with adhesive pads and movable brackets to stabilize catheters and connectors, and a method for securing and managing catheters during saline-administered workflows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single securement device is used to hold the catheter and needleless connector, then the device complexity is reduced, but the reliability of preventing displacement and dislodgement is insufficient
Solution Approach 1:
The securement system is divided into two distinct components: a catheter securement device with first adhesive pad for securing the catheter, and a needleless connector securement device with second adhesive pad for securing the needleless connector. This segmentation allows each device to independently perform its securing function, improving overall reliability without requiring a single complex device
Solution Approach 2:
The movable bracket serves as an intermediary component that connects the needleless connector securement device to the catheter securement device. It allows relative movement between the two securement devices while maintaining their connection, enabling the system to accommodate movement without compromising the securing reliability
2Ease of operation
If the needleless connector is fixed rigidly to the securement device, then the stability is improved, but the ease of operation for accessing the distal end is reduced
Solution Approach 1:
The bracket is designed with movable coupling to the catheter securement device, allowing it to move relative to the securement device. This dynamic connection enables the bracket to move when the distal end of the needleless connector needs to be accessed, while maintaining stability during normal operation
Solution Approach 2:
The bracket is positioned within or adjacent to the catheter securement device, with the needleless connector secured to the bracket. This nested arrangement allows the bracket to move relative to the main securement device while keeping the needleless connector properly positioned and accessible
3Productivity
If clinicians must manually hold the catheter during SAS/SASH workflow, then contamination is prevented, but the productivity is reduced
Solution Approach 1:
The needleless connector securement device automatically holds the catheter in place during SAS/SASH workflow through the adhesive pad and bracket mechanism. The system provides self-service by maintaining catheter position without requiring manual holding by the clinician, enabling both hands to be free for executing the workflow
Solution Approach 2:
The catheter is pre-secured to the needleless connector via the bracket and adhesive pad before the SAS/SASH workflow begins. This preliminary securing action ensures the catheter remains held and protected from contamination throughout the entire workflow without requiring continuous manual intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents catheter and connector displacement, reduces patient injury and contamination risks, and allows clinicians to perform saline-administered workflows without manual holding, enhancing safety and convenience.
Implementation Method 1
an adhesive pad engageable with the second side of the securement device, wherein the adhesive pad comprises an engagement side configured to engage the adhesive pad with the second side of the securement device and an adhesive side configured to adhere the securement device to a patient

AI summary
Fluid delivery securement systems, needleless connector securement systems, and methods for regulating fluid delivery with these systems are disclosed. The fluid delivery securement system comprises a catheter securement system and a needleless connector securement system. The catheter securement system and the needleless connector securement system are primary and secondary securement devices that prevent harmful movement of the fluid delivery devices. The catheter securement system includes a catheter securement device adhered to the patient and a catheter hub comprising one or more catheters. The needleless connector securement system comprises a securement device adhered to the patient. The securement device is movably coupled to a bracket, which can be coupled to different needleless connectors. The needleless connectors, in turn, are coupled to catheters. The bracket can rotate and translate the needleless connector and the catheter relative to the securement device, which facilitates clinician access to the needleless connector and the catheter.
