  • Publication number: 20240325650
    Abstract: A medical syringe reduces medication waste that dispensing medication remaining within the syringe's Luer tip. The syringe plunger incorporates a ramrod with a jag on its distal end that is inserted through the Luer tip's lumen when the plunger is fully advanced into the syringe barrel. A center through bore of a syringe stopper is slidably coupled to the ramrod in fluid-sealed abutting contact. The center bore is initially oriented on the ramrod over the jag. Medication is aspirated into the syringe while the stopper is in its initial, axial position. The last, dose of medication is dispensed by advancing with the plunger with sufficient pressure to abut the stopper into contact with and translate the ramrod jag through the lumen of the Luer tip, thereby dispensing medication that was retained within the lumen.

  • Publication number: 20240316330
    Abstract: Fluid connector systems including first and second connector portions couplable together to form a fluid pathway therethrough, and can resist fluid flow through the connector when the connector portions are separated from each other. A connector portion can include a connector housing, a luer portion, and a deformable valve member. The deformable valve member is disposed within the connector housing and includes a spherical portion extending partially through a valve opening of the connector housing. The spherical portion defines a slit, and the deformable valve member is configured to selectively prevent fluid flow from the housing volume through the valve opening and to deform to expand the slit and permit fluid flow from the housing volume through the valve opening.

  • Publication number: 20240261541
    Abstract: A multi-port distribution hub for vascular access devices (VADs) facilitates sequential administration of multiple medications and VAD flushing by syringes through a catheter hub of an intravenous (IV) catheter without the need to scrub and disinfect the catheter hub after dispensing each individual syringe. A housing manifold of the hub defines a central chamber. A plurality of manifold runners each has a runner outlet in fluid communication with the central chamber, and a runner inlet in fluid communication with a corresponding syringe port. A patient access port is in fluid communication with the chamber. A one-way valve in the central chamber prevents fluid backflow through other syringe ports while dispensing fluid from one of the syringes.

  • Publication number: 20240261510
    Abstract: A single-use medical syringe has a syringe lock that prevents repeated syringe aspiration and dispensing of fluids to patients. A pivoting syringe lock is coupled to the proximal open end of the syringe barrel. The syringe lock has or more cantilever lock forks in continuous, biased, sliding, abutting contact with the plunger. Each lock fork engages a corresponding plunger detent oriented on a proximal end of the syringe plunger, after the plunger is fully advanced within the syringe barrel. The plunger remains locked in an advanced position within the syringe barrel while each lock fork is engaged in its corresponding plunger detent. In some embodiments, a removeable plunger clip is coupled to the syringe to prevent inadvertent advancement of the plunger into the syringe barrel and premature locking of the syringe prior to administration of medication to a patient.

  • Publication number: 20240225486
    Abstract: A syringe with an integrated vein finder is disclosed, which illuminates a potential venipuncture site of a patient and identifies a vein that is suitable for venipuncture with the syringe, for blood collection or intravenous drug administration. The syringe portion of the system includes a syringe barrel and a pointed-tip needle projecting from the distal end of the barrel for venipuncture. An illumination module is coupled to the syringe barrel; it has an illumination source that projects an electromagnetic beam into an illumination zone distal the syringe's pointed tip, for illuminating and identifying a subcutaneous vein. The integrated vein finder and syringe system is operable by a sole clinician, such as a phlebotomist, who can easily manipulate the syringe and illuminate the venipuncture site with one hand, without assistance of another clinician.

  • Publication number: 20240173538
    Abstract: A disinfection cap or device for disinfecting medical connectors. The cap includes a visual indicator that changes color after sufficient scrubbing effort and time have been expended by a clinician to disinfect the medical device, giving positive visual feedback to the treating clinician. An external housing of the cap includes a disinfection medium, such as a disinfectant sponge that is coupled to a rotating collar. The housing is oriented so that the sponge contacts the medical device to be cleaned. Collar rotation in turn rotates the disinfectant sponge against the VAD, providing scrubbing action. A visualization chamber within the cap contains two isolated fluids of distinct colors. As the collar is rotated it mixes the two isolated fluids, changing color of the resultant mixture. When the visualization chamber shows the new, mixed third color, the medical device is disinfected.
