  • Patent number: 6162199
    Abstract: A hand held device for loading a hypodermic syringe from a medicine vial is configured for easy placement of the syringe into a closely conforming channel in the proximal end of the device, with the needle end pointing towards the other end. The other end of the device is configured for easy placement of a standard vial into a closely conforming chamber with its penetrable cap facing the needle tip. Closing the device causes or permits the further action required for piercing the vial with the syringe needle. A sliding pull tab engages the syringe plunger so that gripping and pulling on the tab withdraws the plunger from the syringe, thus drawing fluid from the vial. An amplified or enhanced readout capability visually indicates the dosage of fluid withdrawn from the vial. An auxiliary needle mounted so as to be slightly offset from the syringe, provides for a supplemental piercing of the vial so that make-up air is available when large dosages are drawn from the vial with a single pull of the plunger.

    Abstract: A system and method for automated filling of one or more medical syringes with desired volume(s) and concentration(s) of an injectate solution, such as a contrast solution usable for medical imaging procedures (e.g., x-ray, MRI, ultrasound). The system may incorporate an automated syringe magazine which interfaces with the programmable system controller to deliver the desired number of syringes after the syringes have been filled. Also, the system may utilize a low-pressure pumping arrangement wherein a pumping device engages each receiving syringe and withdraws the plunger of the receiving syringe to pull the desired injectate solution into the receiving syringe by negative pressure.

    Abstract: A method of using a multi-compartment fluid assembly for calibrating an apparatus external to the assembly, while conveniently maintaining sterility. The method includes providing calibration fluid in a closed calibration container disposed within a bag that includes a connector for conveying fluids between the interior of the bag and a conventional intravascular tube. In use, fluids may be directed through the external apparatus and the intravascular tube and into the bag's interior. At an appropriate time, the calibration container is opened and the calibration fluid is withdrawn from the container to the intravascular tube, through the connector, without mixing the calibration fluid with any fluids in a remaining volume of the bag. Subsequently, the calibration fluid is transferred from the intravascular tube to the bag's interior, again through the connector.

    Abstract: A medication dispenser (2, 120) is used to directly fill a syringe (8, 134) with measured amounts of one or more liquid medications, typically two different types of insulin, from containers, such as vials (4, 6) and cartridges (230, 232, 234) each having a septum at one end; each cartridge has a pierceable piston (256) at the other end. The septum of each container is pierced by hollow liquid spikes (54) while hollow gas spikes (56) pierce the septum of the vial and the piston of the cartridge. Liquid is pumped out of the container and air is replaced into the container through the liquid and gas spikes. Two of the cartridges can contain a diluent (231) and a lyophilized component (233) respectively; the diluent in the first cartridge can be pumped into the second cartridge through a one-way valve to create a mixed pharmaceutical which is then pumped into the syringe, with or without another pharmaceutical.

An elongate piston stop (58) is held in place by a piston driver (42) to which the syringe carrier is threadably connected. The syringe carrier is screwed into the piston driver to drive the barrel of the cartridge over the piston, thus forcing the contents of the cartridge through the needle cannula and into the syringe. The invention can also be practiced with the needle cannula piercing the piston so that the movement of the piston into the barrel of the container forces the liquid pharmaceutical through the needle cannula and into the syringe.

  • Patent number: 4623344
    Abstract: A dosing means for facilitating the drawing of respective predetermined volumes of two liquids to be injected, in a single injection, into a hypodermic syringe comprises a first positioning element to hold the body of a removable hypodermic syringe, an axially displaceable plunger, and a second positioning element to hold a removable ampoule containing injection liquid. The two positioning elements are arranged so that the tip of the needle of the hypodermic syringe is inside the ampoule when the syringe and ampoule are located in the device. From the first positioning element a pin protrudes axially and carries first and second stops cooperating with the end of the plunger. When liquid is to be drawn in to the hypodermic syringe the plunger is drawn out until its end part meets the first stop. The first ampoule is then replaced by an ampoule containing a different type of liquid.

  • Patent number: 4617016
    Abstract: Injection device for medical purposes, designed for injection by using a manual hypodermic syringe. It includes a barrel part which in one end has a syringe needle and in the other end a flange; a plunger part having a plunger displaceable in the barrel part, said plunger performing movements, enabling medicine to be sucked into and respectively injected from the barrel portion, and having a gripping part connected with the plunger by means of a plunger rod. The device has an opening in one end, through which the injection syringe can at least partly be introduced into a cavity, and an inner part which is provided with a holding device for the barrel part which is changeable between a releasing position and a holding position, in which the barrel portion is held against movements in its longitudinal direction relative to the inner part. A displacement device is provided for displacing the plunger part between a fore and a rear displacement position.

  • Patent number: 4489766
    Abstract: A device is shown for filling a syringe with a desired quantity of medicine, such as insulin, and is particularly useful for blind people or people with impaired vision who cannot read or see the volume markings on a syringe. The device has an elongate body with a syringe recess for retaining a syringe in position. A bottle recess is provided in the elongate body for sliding a medicine bottle onto the needle of the syringe. The elongate body has a gauge recess adjacent to the position where the syringe plunger would be located allowing the syringe plunger to be fully extracted. A plurality of retractable spacers of different thicknesses are located in the gauge recess to limit the extraction of the syringe plunger and thus gauge or control the quantity of medicine drawn into the syringe. The spacers are rearrangeable and removable to preselect the medicine dosage filling the syringe.

  • Patent number: 4439193
    Abstract: An improved apparatus for aseptically connecting medical liquid containers to a length of flexible tubing comprises a port on the container, a pierceable diaphragm within the port, and a hollow tubular piercing pin connected to the length of flexible tubing adapted for penetrating the pierceable diaphragm. An alignment tray having a bag port cavity integrally formed therein is adapted for receiving and fixedly positioning the bag port and the bag. A guide mechanism integrally formed along the length of the tray is constructed to align the piercing pin and allow it to be slidably joined to the bag port without touch contamination of the port or the pin.

  • Patent number: 4433974
    Abstract: A system for the preparation of parenteral nutrient solutions from two or more substrates such as amino acids and carbohydrates in a virtually aseptic environment. A closed system is formed with the substrate supply containers, incorporating conduit extending from each supply container and connected to the inlet of a multiple transfer valve, a dosing syringe secured to the inlet/outlet connection of the transfer valve and a flexible mixing container secured to the outlet of the transfer valve. Each conduit includes a tube clamp such that each conduit is individually communicable with the transfer valve. With the suction stroke of the syringe plunger, fluid is drawn from one of the supply containers into the syringe. As the solution is ejected from the syringe it exits the outlet of the transfer valve and enters the mixing container.
