Utility
Safety Syringe and Dosage Verification System
2 Feb 23
A dosage verification system for use prior to administering an injection of a medicinal fluid drawn into a medical syringe, the system comprising a medical syringe having a barrel with an outwardly facing, flat indicia display surface, plunger having a plunger seal disposed inside and slidably engaging an inwardly facing wall of the barrel and a plunger handle projecting rearwardly from the barrel, and a hypodermic needle projecting forwardly from the barrel, all in combination with an imaging device configured to view and selectively capture, store or transmit a digital image of the plunger position relative to the barrel when a dose of the medicinal fluid is drawn into the fluid chamber of the barrel prior to an injection to verify and provide a record of the dosage drawn, and to alert a user prior to injection when an incorrect dosage is drawn into the fluid chamber of the syringe.

Utility
Medical Syringe
24 Feb 22
A safety syringe for medical use having an injection molded plastic body with a tubular barrel, a transverse finger flange surrounding the barrel and two upwardly projecting wings with substantially flat, outwardly facing surfaces disposed forwardly of the finger flange, a plunger assembly slidably engaging an inside wall of the barrel, a needle with a tip projecting forwardly from the barrel, and a needle safety shield slidably engaging the body between the wings, wherein the transverse finger flange has a window that allows core pin insertion through the window during injection molding of the body, the plunger assembly has a proximal end cap that is integral with the plunger handle and abuts a rearwardly facing surface of the transverse finger flange, and the needle safety shield has a distal end with a cylindrical needle guard that is forwardly movable following use of the syringe to guard the needle tip.

Utility
IV catheter with retractable needle and laterally offset biasing element and needle retraction cavity
12 Oct 21
An intravenous catheter introducer for medical use having a body, a frontal attachment that is disposed in transverse sliding engagement with a front part of the body, a hub tube assembly that is releasably supported by the frontal attachment, and a retractable catheter insertion needle and needle holder that are biased rearwardly by a spring offset laterally from the needle axis, whereby lateral repositioning of the body relative to the frontal attachment following vascular insertion moves a needle retraction cavity disposed inside the body into substantial coaxial alignment and causes the needle holder to be retracted into the needle retraction cavity.
