  • Patent number: 11097058
    Abstract: Improved apparatus for use with medication in fluid form, which is particularly beneficial for medications having a relatively high viscosity. The 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. When the disclosed syringe adapter is affixed to a pistol-grip or tab-handled syringe, the medication withdrawn into the pistol-grip syringe can be more easily administered from the syringe barrel.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 to the in-place syringe adapter for the injection.

  • Patent number: 11065407
    Abstract: Resuscitation apparatuses and methods for assisted ventilation are described herein. The apparatuses may include functional elements that allow the manual delivery of a prescribed volume to an adult or an infant lung. Furthermore, the apparatuses may inform and assure an emergency worker that an appropriate volume is being delivered and therefore lessen the possibility of barotrauma from over-delivery, or ventilatory distress from under-delivery. In some embodiments, the apparatuses include biomechanical and ergonomic functional elements that allow an adult hand to hold it in place during operation, while at the same time, allowing the user to actuate the apparatus to deliver only the necessary amount of volume suitable for an infant lung. In other embodiments, a volume-controlled design is applied to pediatric and adult resuscitation.
