Novel Double-Needle System That Can Prevent Intravascular Injection of Any Filler

Novel Double-Needle System That Can Prevent Intravascular Injection of Any Filler

A new type of needle system combines 2 parts, an inner needle and an outer needle. The inner needle is used for filler injection and the outer needle acts as a guiding needle that can observe blood reflow when inserting into the vessel lumen during injection process. This new needle system can be used for all kinds of filler, providing real time monitoring for physician and preventing intravasc...

A Novel Needle Structure that Can Avoid Intravascular Injection of Any Filler

With increasing use of dermal fillers, more and more adverse effects are reported. The most devastating one is intravascular injection. We propose a novel needle prototype that allows physicians to prevent intravascular injection.

the incidence of intravascular needle entrance during inferior alveolar nerve block injection

background and aims . dentists administer thousands of local anesthetic injections every day. injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicit...

Comparison of incidence of intravascular injections during transforaminal epidural steroid injection using different needle types

BACKGROUND Infrequent but serious complications of transforaminal epidural steroid injection (TFESI) occur due to inadvertent intravascular injections. A few studies reported that the different needle types can influence on the occurrences of intravascular incidence in TFESI. This study prospectively evaluated whether short-bevel needle can reduce the incidences of intravascular injection of TF...
