Fluid transfer devices and methods of use

Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container. Some embodiments of the device can include a motor and a controller for automatically actuating a plunger of the syringe to transfer the desired amount of fluid.

Method and apparatus for transmitting a digital information signal and vending system incorporating same

A cashless business transaction system (e.g., a vending system, a material tracking system, or a highway toll system) incorporates a method and apparatus for transmitting a digital information signal. A signal generator (311) generates a constant frequency signal. A phase modulator (305) varies the instantaneous phase of the constant frequency signal to represent digital information, thereby producing a phase modulated signal (325). A tuned resonant circuit (307) filters and averages the phase modulated signal to produce a simulated FM signal, and transmits the simulated FM signal via its antenna (309). One such business transaction system (e.g., a vending system) incorporates such a transmitter to facilitate transmission of billing information from a device located within a substantially electrically shielded environment. Another such business transaction system preferably incorporates such a transmitter to facilitate half-duplex transmission of digital information regardless of whether or not the digital information is transmitted from a device located within a substantially electrically shielded environment.

Continuous liquid stream digital blending system

The present invention consists of a method and apparatus providing for the continuous stream blending, preferably on a mass ratio basis, of two or more liquids. Each individual liquid stream is synchronously dosed in precise mass ratio to a common mixing point. The flow of each stream is on-off or digital. Repeated mass ratio doses of defined and matching flow interval, referred to as synchronous digital flow, interspersed with a defined interval of no flow, constitutes digital flow at a net rate sufficient to meet or exceed some required take-away of the blended liquids. In one preferred embodiment, each dose stream flow is produced and measured by a four element apparatus preferably consisting of a servo motor and controller, a precision positive displacement pump, a Coriolis mass meter and a precision flow stream shut-off device. The servo motor and controller establish and control a periodic and intermittent flow rate necessary to displace a defined mass dose in a precisely defined flow interval. The flow interval is measured against a precision millisecond digital clock. The Coriolis mass meter is used only to totalize mass flow to define the desired mass dose during the defined digital flow interval. The flow stream shut-off device ensures precise delivery of the mass dose to the common mixing point. The flow rate of a stream is automatically adjusted by the control electronics until the required mass dose is delivered in the defined flow interval.

InactiveUS20060231519A1Avoiding seal integrity problemGood product containmentCapsLiquid fillingLiquid productFormulary
A container and method are provided for storing fat containing liquid products, such as infant or baby formula, or other milk-based products. The container includes a body defining a storage chamber for receiving the aseptic fat containing liquid product, and a first aperture in fluid communication with the storage chamber. The body does not leach more than a predetermined amount of leachables into the fat containing liquid product and does not undesirably alter a taste profile of the fat containing liquid product. A container closure assembly includes a stopper receivable within the first aperture for hermetically sealing the storage chamber. The stopper includes a first material portion defining an internal surface in fluid communication with the storage chamber forming at least most of the surface area of the container closure that can contact any fat containing liquid product within the storage chamber and that does not leach more than a predetermined amount of leachables into the fat containing liquid product or undesirably alter a taste profile of the fat containing liquid product. A second material portion of the stopper either (i) overlies the first material portion and cannot contact any product within the storage chamber, or (ii) forms a substantially lesser surface area of the container closure that can contact any product within the storage chamber in comparison to the first material portion. The second material portion is needle penetrable for filling the storage chamber with product, and a resulting needle aperture formed in the second material portion is thermally resealable such as by the application of laser energy to seal the product within the storage chamber. A sealing portion of the container closure is engageable with the body prior to needle filling the storage chamber to thereby form a substantially dry hermetic seal between the container closure and body.
