  • 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.

  • Patent number: 12023462
    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: 20240198075
    Abstract: A disinfecting cap for a needleless connector includes an outer housing having a sidewall and an outer guide on an inner surface of the sidewall. The cap also includes an inner housing having an open end sized to receive a distal end of the needleless connector, a sidewall, and an inner guide on an outer surface of the sidewall that interacts with the outer guide of the outer housing. The cap also includes an absorbent member disposed in the inner housing configured to contain a cleaning solution for cleaning and/or disinfecting portions of the needleless connector engaged to the cap. Movement of the inner guide relative to the outer guide causes the inner housing to move axially into the outer housing and to alternate between rotating in a first direction and rotating in a second direction relative to the outer housing.

  • Publication number: 20240139424
    Abstract: A syringe includes a barrel having a proximal end, a distal end having a distal tip defining a channel, and a sidewall extending between the proximal end and the distal end. The syringe also includes a tip cap removably connected to the distal tip of the barrel restricting fluid flow from the channel. The tip cap includes a connector configured to receive the distal tip of the barrel forming a friction engagement with the distal tip, a cap shield connected to and extending about the connector, and a release tab extending proximally from the cap shield that secures the tip cap to the barrel. A prefilled flushing syringe including a predetermined volume of a fluid disposed within the barred of the syringe, as well as methods for expulsion of fluid from the syringe and of assembling the syringe and tip cap are also disclosed herein.

  • Publication number: 20240100246
    Abstract: Pump assemblies for use with an IV set are described herein. A pump assembly includes a rotatable crank, a piston rod, and a diaphragm assembly. The crank includes a crank profile defining a plurality of lobes. The piston rod includes a first follower and a second follower spaced apart from the first follower. The rotation of the crank relative to the piston rod causes the piston rod to reciprocate relative to the crank. The diaphragm assembly includes a housing and a diaphragm member. The diaphragm member is coupled to the housing and cooperatively defines a volume in fluid communication with the IV set. The diaphragm member is movable between an extended position configured to draw in fluid from the IV set and a contracted position configured to expel fluid into the IV set. The diaphragm member is coupled to the piston rod to reciprocate the diaphragm member.

  • Publication number: 20240050647
    Abstract: A dual chamber single-hand pump is described that includes a pump chamber with four fluid pathways. Two pathways are configured to conduct fluid to the chamber and to stop flow therethrough from the chamber, and two pathways are configured to conduct fluid from the chamber and to stop flow therethrough to the chamber. A piston positioned and moveable within the chamber separates two of the pathways from the other two pathways within the chamber. The pump can be held in a single hand by having finger grips for stabilizing the pump and a palm grip for advancing the piston. A return spring can return the piston to the original position when the palm is relaxed to allow expansion of the spring.
