Patent number: 11504519Abstract: The present teachings may generally include a sealing device disposed within a connector (e.g., a patient connector) at an end of catheter tubing, where the sealing device is structurally configured to form a releasable seal for the catheter tubing. That is, when unengaged with a contact portion of another connector or device, the sealing device may be disposed in a first position establishing the seal. Specifically, a channel disposed through a body of the sealing device may be obstructed when in the first position. However, through predetermined engagement with the contact portion of another connector or device, the sealing device may be moved (e.g., rotated) to a second position to establish a fluid pathway through the channel. And, when the predetermined engagement is removed, the sealing device may be structurally configured to automatically move back into the first position to reestablish the seal for the catheter tubing.Type: GrantFiled: September 2, 2020Date of Patent: November 22, 2022Assignee: Fresenius Medical Care Holdings, Inc.Inventors: Orestes Soto Ramirez, Irving Uziel Hernandez Gomez

Patent number: 11446450Abstract: An improved apparatus for use with medication in a fluid form, which is particularly beneficial for medications having a relatively high viscosity. A disclosed syringe adapter has an opening that is relatively large, as compared to a conventional needle, and thus affixing the disclosed syringe adapter to a syringe improves syringeability of higher-viscosity medications. Some embodiments feature a lateral extension that prevents inserting the syringe adapter too far into a medicine bottle, and some embodiments feature a component that assists in firmly grasping. When the disclosed syringe adapter is affixed to a pistol-grip syringe or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered a syringe barrel. In some embodiments, the syringe adapter will be replaced with a needle prior to injecting the medication, while in some other embodiments, the needle is affixed for the injection to the syringe adapter in place.Type: GrantFiled: August 17, 2021Date of Patent: September 20, 2022Inventors: James T.
