The present disclosure relates to a catheter insertion apparatus including a hollow needle body connected to a needle hub, and a catheter that removably fits over the needle body. The needle body has a sharp distal needle tip for piercing a blood vessel wall. An internal flow passage of the needle hub is in fluid communication with the hollow needle body. An elongated housing is connected to the needle hub and includes a lumen in fluid communication with the internal flow passage of the needle hub. An integrated guide assembly is slidably mounted to the housing and is operable to move between a retracted position and an extended position. A flashback chamber is operable to receive a continuous flow of blood before, during, and after movement of the guide assembly between its retracted and extended positions. A safety guard may provide protection from the sharp needle tip.

Catheter insertion apparatus with continuous visible flashback

A catheter insertion device that allows for single-handed insertion of the catheter within the vasculature of the patient is disclosed. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guidewire partially within the handle and the needle cannula, and a first actuator connected to the handle and the guidewire. The guidewire is movable relative to the handle in a distal direction away from the handle, and in a proximal direction towards the handle. A catheter assembly is removably coupled to the handle and is configured to slide on the needle cannula. A catheter hub may be connected to a proximal end of the catheter, and a catheter advancer base may be releasably connected to the catheter hub. The catheter insertion device may also include a needle support pivotally connected to the handle for supporting the needle cannula on a cantilever portion thereof.

Catheter insertion device

A vascular access training simulator system for training intravascular insertion of a medical device is disclosed. The vascular access training simulator system includes an anatomical training model having clinically relevant ultrasonic properties representative of ultrasonic properties of a human body site for ultrasound imaging. The training model includes a transparent housing, a transparent simulated tissue, at least one simulated blood vessel suspended in the tissue, and a layer of simulated skin covering the housing and the tissue. A first imaging device is records a first video showing a view of an insertion site outside of the simulated skin. A second imaging device records a second video showing the simulated blood vessel through the transparent simulated tissue. A third imaging device is shows an ultrasound view of the simulated blood vessel and the simulated tissue. A monitor displays a composite view of all three videos simultaneously on a single screen.

Vascular access training simulator system and transparent anatomical model

An assembly is provided for accessing a superior vena cava of a patient without visualization of a vasculature of the patient. A stylet has an elongated body including a core wire disposed within a tubular body, the core wire having a pre-formed shape in a first state and a straightened shape in a second state. A first portion of the core wire has a substantially straight shape in the first state. A second portion of the core wire has a first pre-formed bend in the first state. A third portion of the core wire has a substantially straight shape in the first state. A fourth portion of the core wire has a second pre-formed bend in the first state. A fifth portion of the core wire has a substantially straight shape in the first state and includes a narrow segment that increases deflection of the distal tip.
