  • Patent number: 11446447
    Abstract: A retractable needle assembly includes a housing having a sidewall defining a hollow bore, and an elongate plunger, the distal end of the plunger forming a reservoir within the hollow bore for containing a fluid therein. The plunger is adapted for slideable movement within the hollow bore. The assembly includes a hub disposed within the hollow bore and at least partially supporting a cannula therewith, and a needle retraction member engaged with the hub for manually selectable advancement with respect to a portion of the housing. The needle retraction member may be advanced from an initial position in which at least a portion of the needle is disposed outside the housing, to a retracted position in which the needle is fully surrounded by the housing. The elongate plunger may be advanced about the hub for extracting the fluid into the reservoir or expelling the fluid from the reservoir.

  • Patent number: 11446450
    Abstract: 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 When the disclosed syringe adapter is affixed to a pistol-grip syringe or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered a syringe barrel.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.

    Abstract: An injection device including a barrel having a medicament reservoir therein capable of fluid communication with a needle assembly at a distal end thereof and sealed at a proximal end thereof with a stopper. The injection device further includes a plunger rod having a distal rod end which is couplable with said stopper, wherein, when the plunger rod is coupled to the stopper, forward axial movement of the plunger rod causes forward axial movement of the stopper coupled thereto into the medicament reservoir in order to expel medicament through the needle assembly. Further, the plunger rod can be decoupled from the stopper by applying a rearward axial force on the plunger rod, said rearward axial decoupling force being less than a rearward axial force required to move the stopper rearwardly with respect to the barrel.

  • Patent number: 11285298
    Abstract: A catheter insertion device (10) is provided for positioning and inserting a catheter (14), particularly a midline catheter into a patient. The insertion device (10) includes an introducer needle (18) that extends from the distal end of the catheter during insertion. A manually operated actuator assembly (20) is movable with respect to a housing for deploying the catheter (14) over the distal end of the introducer needle (18). A step-wise movement of the actuator (20) advances the catheter (14) in stages over the introducer needle (18). A shuttling or indexing mechanism (60, 76) advances the catheter and prevents retraction of the catheter once deployed.

  • Patent number: 11278702
    Abstract: An insertion tool for inserting a catheter into a patient's body is disclosed. The insertion tool unifies needle insertion, guidewire advancement, and catheter insertion in a single device. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with at least a portion of the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly may be included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. In one embodiment a catheter advancement assembly is also included for selectively advancing the catheter into the patient. Each advancement assembly can include a slide or other actuator that enables a user to selectively advance the desired component.

  • Patent number: 11266792
    Abstract: A Hypodermic Needle Safety Guard intended for sharps prevention and safer hypodermic needle use during all stages of an injection process. The Safety Guard may include two symmetrically positioned multi-featured arms that include spring tension, multiple hinges and needle locks. These arms may connect a proximal Luer body and a distal alignment tip thereby enabling the guard to open, close and lock on a needle when manual pressure is applied. The Guard position during hypodermic needle use tends to prevent sharps injury by adjusting the exposure of the Needle tip.

  • Patent number: 11260173
    Abstract: A needle assembly including a needle having a sharpened end and an opposing end and a needle tip shield for shielding the needle. The needle tip shield includes a needle shield connectable to a base and a needle hub fixedly connected to the opposing end. The needle shield and needle hub displace relative to each other from a first state, in which the sharpened end of the needle is exposed outside the needle shield, to a second state, in which the sharpened end of the needle is shielded by the needle shield. An actuation button is movably connected to the needle hub to maintain the needle shield and needle hub in a releasable locked state in a first button position relative to the needle hub and to permit the needle shield and needle hub to displace relative to each other in a second button position relative to the needle hub.
