Abstract

A bi-directional cannula feature capture mechanism (30) is described herein. Generally, the capture mechanism comprises an inner housing (80), an outer housing (100), and a cannula (40). The inner housing comprises a proximal and a distal cannula feature mating component. The outer housing is adapted to slidably receive the inner housing in a proximal direction. Additionally, the cannula extends through the inner housing and the cannula's feature has a proximal engagement and a distal engagement. The proximal and distal engagements are respectively configured to irreversibly engage the proximal and distal cannula feature mating components when the cannula tip is moved into a shielded position.

Description

Technical field [0001] In general, the present disclosure relates to vascular access devices and related methods. More specifically, the present disclosure discusses a two-way intubation feature restraining mechanism that is adapted to restrain the intubation feature in a manner that locks the cannula in the shielding position. The two-way intubation feature restraint mechanism can be used for catheter assembly. Background technique [0002] In general, vascular access devices are used to communicate fluids with the patient's vasculature. For example, catheters are used to inject fluids (e.g., physiological saline solution, medication, and / or all parenteral nutrition) into the patient, draw fluids (e.g., blood) from the patient, and / or monitor various aspects of the patient's vasculature. Kind of parameters. [0003] Intravenous (IV) catheter assemblies belong to various types of vascular access devices. The over-the-needle peripheral IV catheter is a common IV catheter structu...
