Abstract: The disclosed embodiment relates to an injection device that is a single patient use, disposable device containing a needle and a cartridge containing a drug, pharmaceutical product or other injectable agent. The device is initially provided in a pre-armed state in a first engagement configuration wherein the needle is separated from the septum of a cartridge. To arm the injection device, the professional urges the device from the first engagement or pre-armed configuration to a second engagement or armed configuration wherein the needle pierces the septum and provides a sterile fluid path to the drug, pharmaceutical product or other injectable agent contained within the cartridge. The disclosed embodiment is particularly adaptable to dental anesthetic applications, as well as other medical and veterinary applications.

Abstract: A syringe for administering medicament from a cartridge. The syringe includes a sleeve having an interior for receiving the cartridge extending between a distal hub and a proximal opening. The syringe has a cap selectively covering the proximal opening for retaining the cartridge in the interior of the sleeve. The cap includes a finger grip extending outward from the sleeve for engaging fingers of a user. The syringe also has a plunger rod movably connected to the cap. The plunger rod has a distal connector for selectively connecting the rod to the cartridge plunger when the cartridge is received in the interior of the sleeve to push medicament from the cartridge reservoir as the plunger rod moves with respect to the cap.

Abstract: A safety needle assembly is disclosed which includes a a needle assembly and a needle guard. The needle guard is supported about a needle of the needle assembly and is positioned to engage an enlarged diameter portion of the needle during withdrawal of the needle guard from the needle to effect an inversion of the needle guard about a sharpened tip of the needle.

Abstract: A method for coupling an ECG monitor with an incompatible ECG lead set includes the steps of providing an ECG adapter including an adapter body having at least one monitor connector adapted for coupling to an input of an ECG monitor and at least one lead set receptacle adapted for coupling to a connector of an ECG lead set incompatible with the input of the ECG monitor, coupling the at least one monitor connector of the adapter body with the input of the ECG monitor and coupling the at least one lead set receptacle of the adapter body with the connector of the ECG lead set to thereby electrically couple the ECG lead set with the ECG monitor.

Abstract: The present disclosure relates to fluid delivery devices for supplying a fluid, e.g., a flush medium, to a medical device, e.g., a vascular access device, inexpensively. The fluid delivery device includes a collapsible body defining a fluid reservoir and a connector for securing the fluid delivery device to the medical device. The collapsible body can include a bellows or pleated structure. In addition, structure including levers or plungers can be provided to collapse the body.

Abstract: The disclosed embodiment relates to an injection device that is a single patient use, disposable device containing a needle and a cartridge containing a drug, pharmaceutical product or other injectable agent. The device is initially provided in a pre-armed state in a first engagement configuration wherein the needle is separated from the septum of a cartridge. To arm the injection device, the professional urges the device from the first engagement or pre-armed configuration to a second engagement or aimed configuration wherein the needle pierces the septum and provides a sterile fluid path to the drug, pharmaceutical product or other injectable agent contained within the cartridge. The disclosed embodiment is particularly adaptable to dental anesthetic applications, as well as other medical and veterinary applications.

Abstract: A needle and receiver assembly for use with a syringe cartridge filled with medicine includes a cartridge receiver having a hollow interior, an open end sized for receiving at least part of the syringe cartridge, and a closed end opposite the open end. The assembly includes a needle mounted on the receiver having a fluid passage extending between a sharp delivery tip at a distal end of the needle and a sharp access tip at a proximal end of the needle opposite the delivery tip positioned inside the hollow interior of the receiver. The assembly includes a cutter movably mounted in the hollow interior of the receiver for cutting the diaphragm of the cartridge when received in the hollow interior of the receiver.

Abstract: An automatic external defibrillator configured to deliver electrical pulses and/or shocks to a heart of a patient during a cardiac emergency includes a housing supporting an electrical connector; a defibrillator electrode delivery system supported on the housing and a pair of defibrillation electrode pads supported by the defibrillator electrode delivery system. Each of the pair of defibrillation electrode pads is pre-connected to the electrical connector of the housing. A hydrogel layer of each defibrillation electrode pad is retained by the defibrillator electrode delivery system in such a manner so as to reduce a moisture vapor transmission rate thereof.

Abstract: A safety syringe system including a safety syringe and an injection site preparation patch adapted for use with the safety syringe. The safety syringe includes a syringe body and a safety shield slidably disposed about the syringe body. The injection site preparation patch has a tissue-facing side and a syringe-facing side, and may include a substrate, a syringe adhesive layer adapted to adhere to a distal flange of the safety shield, a hydrogel layer adapted to adhere to tissue, and removable release liners disposed on either side. The patch may include a medicament, anesthetic, or a thermal compound. Adhesion between the patch and the flange is less than adhesion between the patch and tissue, so that the patch adheres to the shield with sufficient strength to enable the shield to slide over the needle upon withdrawal, but with insufficient strength to cause the patch to pull away from a patient's skin.
