    Abstract: Syringe assemblies are provided that can include a valve within a plunger having a fluid channel extending longitudinally therethrough and along the channel, the valve including a piston extending substantially normally to the channel and configured to slidably engage the plunger along the extension. Syringe assemblies can also include: a syringe barrel having a first cross sectional diameter; a syringe piston configured to operatively couple with the barrel; a fluid channel extending the length of the piston; a vial port extending from an end of the piston, the vial port having a second cross sectional diameter, the second diameter being greater than the first diameter. Methods for controlling fluid along a fluid channel within a syringe plunger are also provided. The methods can include extending a piston in one direction normally to the fluid channel to provide fluid communication between two sections of the fluid channel.

  • Patent number: 8480656
    Abstract: A dispensing device for dispensing medicaments to a patient that is made up of first and second stand-alone, interconnectable assemblies. The first of these assemblies comprises a fluid reservoir assembly that houses a fluid reservoir defining component while the second assembly comprises a fluid delivery and control assembly that includes a novel flow control means that functions to control the flow of medicinal fluid from the fluid reservoir of the first assembly toward the patient via a plurality of fluid flow control passageways. Because the stand-alone fluid delivery and control assembly is initially totally separate from the fluid reservoir assembly of the apparatus, the fluid flow passageways of the fluid delivery and control assembly can be effectively sterilized using conventional gamma ray sterilization techniques without adversely affecting the medicament contained within the fluid reservoir of the apparatus.

  • Patent number: 8317753
    Abstract: A compact, nonelectric fluid dispenser for use in controllably dispensing beneficial agents such as propofol and dexmedetomidine hydrochloride to patients. The dispenser includes a fluid flow control assembly that precisely controls the flow of the medicament solution to the patient and embodies a collapsible drug container that can be filled in the field with the beneficial agents to be delivered to the patient. The unit-dose fluid dispenser of the invention is presented in a sterile and aseptic manner, where the drug has been pre-filled in the system, so that the practitioner cannot mistakenly give the wrong drug to the patient. The dispenser uniquely provides a more efficient medicament delivery system for procedure rooms, such as the endoscopy center, so that a greater number of patients can be treated per day at a higher standard of care with increased profits for the healthcare provider.
