Problems solved by technology

Systems that rely on magnetizing the cannula prior to insertion can more reliably measure actual tip position, but this method suffers from variation in consistently magnetizing the cannula because it relies on the clinician placing the needle in the Magnetic device to magnetize the needle
Both systems utilize a magnetic field generated by a portion of the cannula subassembly; therefore, relative motion between the needle hub and catheter adapter subassembly cannot be measured or predicted

Abstract

Systems, methods, and devices are described that include a catheter adapter subassembly (112, 12, 212, 312, 512, 612, 712) that includes a magnetic feature. The system includes such a catheter adapter subassembly (112, 12, 212, 312, 512, 612, 712) and a needle subassembly (114, 14, 214, 314, 514, 614) that includes a magnetic feature and is capable of using magnetic The gauge determines the relative motion of the catheter adapter subassembly (112, 12, 212, 312, 512, 612, 712) and the needle subassembly (114, 14, 214, 314, 514, 614).

Description

technical field [0001] The principles and embodiments of the present disclosure relate generally to devices, systems and methods that include permanent magnets and magnetizable features. Background technique [0002] Traditionally, clinicians cannot see the needle and catheter tubing passing through the skin tissue to reach the vein during catheterization. Therefore, they must rely on their first-hand experience of needle insertion combined with tactile perception to successfully identify the location of the vein. This can be a difficult task when attempting to access small veins deep under the skin, increasing the patient's risk of excessive pain and / or injury. [0003] Emerging procedure guidance systems utilize a combination of ultrasound and magnetic techniques to provide visualization of subcutaneous anatomy and device location along in-plane and out-of-plane orientations. This combination of ultrasound and magnetic methods also allows the projected or anticipated ins...
