Problems solved by technology

In some cases, these debris (e.g., fibrin / platelet clots) around the PIV can lead to reduced blood flow in the portion of the vein surrounding (e.g., upstream and downstream) the inserted PIV, which in turn leads to inappropriate and / or low efficient suction

Embodiment Construction

[0050] In some embodiments, an apparatus includes a catheter, an introducer, and an actuator. The catheter has a proximal portion and a distal portion and defines a lumen therethrough. The introducer has a proximal portion and a distal portion, and defines an interior volume configured to movably receive a catheter. The distal portion of the introducer has a lock configured to couple the introducer to the indwelling peripheral intravenous line. The actuator is movably coupled to the introducer and has a first portion disposed outside the introducer and a second portion disposed within the interior space of the introducer and coupled to the proximal end portion of the catheter. The actuator is configured to move relative to the introducer to move the catheter between a first position in which the catheter is disposed within the introducer and a second position in which The distal portion of the catheter is disposed beyond the distal portion of the introducer such that when th...

Abstract

An apparatus includes a catheter, an introducer, and an actuator. The distal portion of the introducer is configured to couple to an indwelling peripheral intravenous line. The actuator is movably coupled to the introducer and is configured to move the catheter between a first position in which the catheter is disposed within the introducer and a second position in which The distal portion of the catheter is located distal to the introducer. The first portion of the actuator is disposed on the exterior of the introducer and is in contact with the outer surface of the introducer such that (1) the longitudinal axis defined by the second portion of the actuator is not parallel to the longitudinal axis defined by the introducer (2) The second portion of the actuator exerts a force on the proximal portion of the catheter to increase internal stress within a portion of the catheter.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Provisional Patent Application Serial No. 62 / 474,202, filed March 21, 2017, entitled "Devices and Methods for Fluid Transfer Through a Placed Peripheral Intravenous Catheter," the disclosure of which is incorporated by reference in its entirety. into this article. technical field [0003] Embodiments described herein relate generally to fluid delivery medical devices. More specifically, embodiments described herein relate to devices and methods for delivering fluids to and from a patient through a placed peripheral intravenous catheter. Background technique [0004] The typical hospitalized patient encounters a needle every time a doctor orders a lab test. The standard procedure for blood extraction involves "sticking" a vein in a patient's arm or hand with a metal needle ("butterfly needle"). Blood drawing is a manual and labor-intensive process, requiring hours ...
