Flow restrictors for use with a syringe or without a syringe are disclosed for dispensing a liquid medicine for an infant or child. The flow restrictors include a cover having a raised ring, a sleeve for insertion into a bottle, a self-sealing orifice for dispensing the medicine and including an annular cylinder having vertical supports or ribs which extend outward and engage the inside wall of the sleeve. The sleeve includes one or more external protrusions.

A closure for dispensing one or more active agents into a container comprises a sealed or sealable chamber having a breakable wall and a hollow piston slidably mounted in a piston guide. Said hollow piston comprises an outer wall having an end in the chamber and at least one ventilation aperture. Said end has a cutting formation. Said hollow piston is slidable in the piston guide between a ventilation position in which the at least one ventilation aperture allows ventilation of the chamber and a sealed position in which the at least one ventilation aperture is sealed to prevent ventilation of the chamber and a deployed position in which the cutting formation has broken through at least a portion of the breakable wall. The outer wall has a retaining formation which engages with the piston guide to releasably resist sliding of the hollow piston between the ventilation position and the sealed position and the deployed position. The hollow piston may have an outer wall, and said outer wall has an end within the chamber, facing the breakable wall, wherein the cutting end has a first edge having a cutting formation and a gap in said cutting formation.

The invention is a needle valve comprising at least one hollow needle and a seat. The hollow needle is comprised of a smooth surfaced hollow shaft and a port adapted to allow fluid communication between the interior and the exterior of said needle located in the side of the shaft at the distal end close to the tip of said needle. The seat comprises at least one bore adapted to accommodate one of the at least one needles through it. The needle and the bore can move one relatively to the other and the bore is provided in, or is fitted with, resilient material such that the outer diameter of the needle is greater than the inner diameter of at least part of the bore. As a result the passage of the shaft of the needle in the bore creates a closely-matched shaft and sheath, which blocks the passage of fluid through the port.

An exemplary vial adapter may include a moveable member, an elongated member with a first passage, a second passage coupled to an expandable first reservoir, and a third passage coupled to an expandable second reservoir. In a first orientation of an exemplary vial adapter, a fluid may be directed through the first passage into the first reservoir or the second reservoir. In a second orientation of an exemplary vial adapter, a fluid may be drawn through the first passage and a fluid drawn through an air passage into the second passage. In a second orientation of an exemplary vial adapter, a fluid may be directed through the first passage and through the third passage into the second reservoir. In a first orientation of an exemplary vial adapter, a moveable member may be activated to direct a fluid from the second reservoir through the third passage.

Various aspects of the subject disclosure relate to a compounder system having a cartridge that includes controllable fluid pathways. One or more rotary piston pump/valves may be used to move fluid and/or gasses through the various fluid pathways of the cartridge. For example, the cartridge may include a dedicated rotary piston pump/valve for each process that moves fluid and/or gas through the cartridge. When turning, the rotary piston pump/valve acts as a pump to move the fluid or gas, and when the rotary piston pump/valve stops turning, it effectively acts as a shutoff valve, preventing any fluid flow. Magnetic couplers for the cartridge may be provided on a pump head of the compounder system.

A safety-engineered, one-time use, syringe adaptor-connector system restricts access to medical vials and intravenous bags (e.g., common reservoirs) using a valve and providing a barrier to inserting a needle in the reservoir.

A liquid transfer device is provided having a trifurcated body that includes a vial adapter at a first end configured to telescopically mount on the crown of an IV bottle to puncture a stopper in the crown with a cannula, an IV port extending from an opposing second end of the trifurcated body, and a needleless self-sealing port extending from a third end of the trifurcated body and configured to couple with the male connector of an additive transfer device. Methods of using the liquid transfer device with an IV bottle, additive transfer device, and an infusion set to prepare an infusion liquid for administration to a patient are also provided.

The invention generally relates to prefilled disposable medication devices, method of making, and using to store, contain and deliver at least a diluent for allergenic extract and more particularly to a prefilled cartridge containing a diluent for allergenic extract for use with an injection pen for allergy treatments.

A filling aid. The filling aid includes a locking portion including a groove feature; and a locking feature having a locked and an unlocked position; and a filling syringe holder slidably attached to the locking portion, the filling syringe holder including a filling needle cradle portion having a tongue feature; and a needle housing portion comprising at least one tab having a starting position and a filling position, wherein the groove feature configured to accommodate the tongue feature, and wherein the locking feature interact with the filling syringe holder wherein when the locking feature moves from the locked position to the unlocked position the needle housing portion moves from the starting position to the filling position.

A syringe assembly for administration of a neurotoxin, the syringe assembly comprising: a syringe comprising: a clear syringe barrel with dosage markings completely encircling the clear syringe barrel; and a plunger having a plunger body and a clear inverted plunger tip; and a needle assembly comprising a needle and a sealing hub for removably attaching the needle assembly to the syringe, wherein the needle is approximately 0.15 inches to approximately 0.3 inches in length and has a gauge of approximately 27 gauge to approximately 35 gauge.
