Patent number: 11931533Abstract: A safety intravenous catheter that includes a passive release feature. The catheter assembly includes ready, safe, and released positions. In the release position, a retainer being in a proximal retainer position relative to a collar enables release of the catheter hub from the catheter insertion device. The sharp tip of the insertion needle remains inaccessible in the release position in order to prevent unwanted needle sticks.Type: GrantFiled: January 12, 2023Date of Patent: March 19, 2024Assignee: Smiths Medical ASD, Inc.Inventors: Gursel Akcay, Harsh D Chheda, David J Goral, Thomas T Koehler

Publication number: 20240071593Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.Type: ApplicationFiled: October 24, 2023Publication date: February 29, 2024Inventors: Anna Leigh DAVIS, Scott M.

Patent number: 11369749Abstract: A safety catheter includes a catheter hub, a needle cannula having a tip, and a tip protector. The tip protector includes an outer member and an inner member therein. The outer member has a projection releasably engaging the catheter hub. The inner member has a pair of arms extending to free ends from a base. The inner member is axially shiftable relative to the outer member between a first position wherein the needle tip is distal of the tip protector and the free ends of the arms are spread apart such that the distal tip is not shielded, and a second position wherein the tip is within the inner and outer members and the free ends of the arms are brought into close proximity such that the distal tip is shielded. The inner member is entirely received within the outer member in both the fort and the second positions thereof.Type: GrantFiled: April 26, 2019Date of Patent: June 28, 2022Assignee: SMITHS MEDICAL ASD, INC.Inventors: Thomas T Koehler, Kathryn L Felicito, Harsh Chheda, Oscar R Abriles
