AI Technical Summary

Technical Problem

Existing medical fluid delivery devices are prone to unintentional displacement or dislocation due to external forces during use, leading to patient injury and infection. Furthermore, it is difficult to maintain the sterilization of catheters in SAS and SASH procedures, affecting the convenience of operation.

Method used

The primary fixation system directly attaches the catheter to the skin, while the secondary fixation system uses a support and adhesive pad to attach the needleless connector and extension tubing to the patient. The combination of rotatable and translational engagement features ensures the device is stable and easy to use in clinical practice.

Benefits of technology

It effectively prevents catheter displacement and dislocation, reduces patient injury and infection risk, and allows clinicians to perform SAS or SASH procedures without holding the catheter, improving the convenience and safety of the procedure.

Abstract

Fluid delivery securement systems and needleless connector securement systems are disclosed. The fluid delivery securement systems include 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 a fluid delivery device. The catheter securement system includes a catheter securement device that adheres to a patient and a catheter hub that includes one or more catheters. The needleless connector securement system includes a securement device that adheres to a patient. The securement device is movably coupled to a cradle that is capable of being coupled to different needleless connectors. The needleless connectors, in turn, are coupled to catheters. The cradle is capable of rotating and translating the needleless connectors and catheters relative to the securement device, which facilitates clinician access to the needleless connectors and catheters.
