Abstract: A needle cover is disclosed which includes a site preparation tip at a distal end of a needle cover body. The tip may be configured with rounded and/or beveled edges in order to facilitate material removal from a cannulation site. The proximal end of the needle cover body may include features to facilitate handling, removal of the needle, and operation of the needle cover in removing material, such as a scab, from a cannulation site.

Abstract: Systems and methods for administering drugs to a patient, including a syringe system. The syringe system includes a plastic needle coupled to an end of a syringe barrel, the needle including a proximal taper and a distal taper. A cannula assembly is removably coupled to the plastic needle, the cannula including mating surfaces for the proximal and distal tapers of the plastic needle. The syringe system can also include a cannula cover with a first and second end with different sizes to respectively attach to the cannula assembly and the barrel when the cannula assembly is removed. The cannula may have a distal tip cut at an angle to ensure maximum removal of drug from a given vial.

Abstract: A transducer protector including at least two spaced apart filter membranes. The transducer protector may include a body positioned between two tubular connectors, each of which contains an axially aligned lumen. The body lumen may be separated from the lumen of each of the tubular connectors, respectively, by the filter membranes. An indicator may be disposed in the body to alert a user that the filter membrane has been breached by a contaminant so that the user can take immediate steps to prevent further contamination of the system. The indicator may display a change in an absorbance spectra peak at a wavelength ranging from approximately 200 nm to approximately 800 nm upon reacting with bodily fluid.

Abstract: A Safety Arteriovenous Fistula (AVF) winged safety needle device provides a safety feature including a protective shield with handling wings, which when placed in cooperating relationship, allows accommodation of a blood collection needle and a hub. The Safety AVF provides a reliable and user friendly first releasable locking mechanism in an insertion position and a second unreleaseable locking mechanism in a protected position. The Safety AVF also allows for rotation of the needle after cannulation in order to maximize blood or fluid flow to or from a vessel.
