  • Publication number: 20110008825
    Abstract: A system for conducting the identification and quantification of micro-organisms, e.g., bacteria in urine samples which includes: 1) several disposable cartridges for holding four disposable components including a centrifuge tube, a pipette tip having a 1 ml volume, a second pipette tip having a 0.5 ml volume, and an optical cup or cuvette; 2) a sample processor for receiving the disposable cartridges and processing the urine samples including transferring the processed urine sample to the optical cups; and 3) an optical analyzer for receiving the disposable cartridges and configured to analyze the type and quantity of micro-organisms in the urine sample. The disposable cartridges with their components including the optical cups or cuvettes are used in the sample processor, and the optical cups or cuvettes containing the processed urine samples are used in the optical analyzer for identifying and quantifying the type of micro-organism existing in the processed urine samples.

  • Publication number: 20090275458
    Abstract: High-throughput centrifugation of batches of samples is achieved by dividing a single centrifugation run of a batch of samples into two or more staggered, discrete spins with fewer samples and in which the availability of centrifuge slots for loading or unloading of samples and the subsequent delivery of experimental results can be enhanced. The methodology is particularly useful in situations where multiple samples need to be processed rapidly, for example, as part of a STAT blood typing program in urgent care facilities prior to blood transfusion.

    Abstract: An analytical instrument for analyzing fluids. The instrument includes a cartridge carousel assembly which receives analytical cartridges. The analytical cartridges include a centrifugal force-operated sample metering/separation system, a pressure-operated sample transport system, and a test element which provides a detectable analytical property of a fluid sample. The cartridge carousel assembly includes a cartridge rotor plate which has a plurality of cartridge ports which receive the cartridges. A rotary drive mechanism rotates the cartridge rotor plate to provide rotation of the plate which activates the centrifugal force-operated sample metering/separation system of the cartridge. The instrument includes a sample transport actuator which activates the pressure-operated sample transport system of the cartridge. In addition, the instrument includes a detector which measures the detectable analytical property of the fluid sample after the sample metering and transport systems have been activated.

  • Patent number: 5882342
    Abstract: A syringe for giving medical injections which has an internal mechanism for retracting the needle into the syringe after the injection has been given and locking the needle and plunger inside the barrel of the syringe to reduce the risk of accidental needle pricks. In one embodiment the needle is retracted by a tension spring into a compartment inside a hollow plunger and in the other embodiment the needle is propelled by a compressed spring into a compartment within the plunger. In both embodiments, the interior of the hollow plunger is hydraulically sealed off by a barrier from the fluid chamber of the syringe to prevent fluid from entering the interior of the hollow plunger.

The dispenser head is operable for directing medication from the delivery tube to the contact surface and on to the mucous membrane to be absorbed by the mucous membrane and distributed in a body of a patient. In a preferred embodiment of the invention, the dispenser head includes a portion of compressible foam which is configured to fit within the rectal cavity of a patient. The dispenser head channels, wicks or otherwise directs medication to the rectal mucous membrane to be absorbed thereby.

  • Patent number: 5599581
    Abstract: A method for dispensing or depositing particulate material includes accumulating particulate material in a nozzle having an opening at the bottom for discharging the particulate material, and applying positive air pressure to a buffer chamber positioned in communication with the accumulation of particulate material to start and control the flow of particulate material through the opening and applying negative pressure to the buffer chamber to stop the flow of particulate material. An unobstructed interface can exist between a surface of the particulate material and air in the buffer chamber. In one embodiment, roofing shingle granules are applied intermittently to a moving coated asphaltic sheet through a slot to form strip roofing shingles.

  • Patent number: 5520889
    Abstract: A method for applying granules to a coated sheet, and in particular a coated asphaltic sheet for use in the manufacture of roofing, comprises controlling a fluid (e.g., pneumatic) counterflow through the discharge opening of a nozzle which holds an accumulation of granules therein to rapidly stop or otherwise modify the flow rate of granules onto the sheet. A buffer chamber is in communication with the granule accumulation in the nozzle, and an apparatus modifies the pressure in the buffer chamber to generate the desired fluid flow through the nozzle opening. A vacuum source provides a negative pressure for a pneumatic counterflow, and a positive pressure source is utilized to increase pressure in the buffer chamber to act as a discharge assistant.
