CAP FOR A PATHOGEN SAMPLE TUBE
The invention is a cap for a pathogen sample tube, the tube having an open end and the cap being configured to secure the open end of the tube to prevent spillage of any sample stored in the tube. The cap includes a first pierceable protective film section configured to enable an automated pipette or other sample withdrawal system to pierce the protective film section and to aspirate at least some of the sample. The cap also includes a second pierceable protective film section lying underneath the first pierceable protective film section; the film sections are separated by an air gap, that is approximately 2 mm in depth. The film sections are made from a thin aluminium foil that is approximately 25 microns thick, with a thin lacquer coating on its upper side and a co-extrusion coating, such as a polymer coating, on the lower side.
Method and device for laboratory formulation and chemical vending
An automatic chemical solution formulating device combines and mixes stored solids and liquids into user specified formulations and dispenses those formulations into containers. Chemical solids are stored in cartridges of material separated into predetermined dosages (for example in reeled blister packs), avoiding the need for weighing during formulation. Elements include user interface, computer-controlled automated loading and unloading port for reagent-containing cartridges, cartridge conveyor system, reader for identifying cartridges, blister-pack strip drive system, punching mechanism to release reagents, portioning chamber to mix solvent with solids or liquids with optional portioning, accommodating formulation delivery port, position sensors, liquid flow measuring devices, liquid and gas pumps and valves, and label printer. The combination of these elements allows high-speed formulation and dispensing of user-specified formulations.
Diagnostic test system and method utilizing a closure/sample dispensing mechanism to dispense a sample subvolume for testing
A diagnostic test system, including: a diagnostic test assembly and a diagnostic test apparatus to perform a test on a biological or environmental sample; the diagnostic test assembly includes: a sample preparation reservoir to receive the sample into a sample preparation fluid, such that a swab carrying the sample can be used to stir the preparation fluid and to wash the swab; a sample dispensing mechanism for insertion into the sample preparation reservoir; a closure to seal the sample preparation reservoir; at least one diagnostic test reservoir coupled to the sample preparation reservoir; and at least one seal between the sample preparation reservoir and the diagnostic test reservoir to prevent fluid movement between the respective reservoirs; wherein the sample dispensing mechanism is operable to disrupt the seal to allow sample fluid to enter the diagnostic test reservoir from the sample preparation reservoir, and to dispense a predetermined amount of fluid.
FLUID HANDLING USING RECEPTACLE MARKING FOR NEEDLE POSITIONING
A fluid handling unit is configured for handling a fluid contained or to be contained in a receptacle bearing a marking. The unit includes a needle having an elongated shape with an open end and for aspirating the fluid from the receptacle and/or dispensing the fluid into the receptacle. The fluid handling unit further includes a needle drive for positioning the needle with respect to the receptacle, a detection unit for detecting the marking of the receptacle, and a control unit. The control unit is configured for analyzing the detected marking for determining at least one feature that is part of the marking or the marking itself, determining a target position based on the detected at least one feature, and operating the needle drive to position the open end of the needle relative to the determined target position.
Systems, methods, and apparatuses to image a sample for biological or chemical analysis
A fluidic device holder configured to orient a fluidic device. The device holder includes a support structure configured to receive a fluidic device. The support structure includes a base surface that faces in a direction along the Z-axis and is configured to have the fluidic device positioned thereon. The device holder also includes a plurality of reference surfaces facing in respective directions along an XY-plane. The device holder also includes an alignment assembly having an actuator and a movable locator arm that is operatively coupled to the actuator. The locator arm has an engagement end. The actuator moves the locator arm between retracted and biased positions to move the engagement end away from and toward the reference surfaces. The locator arm is configured to hold the fluidic device against the reference surfaces when the locator arm is in the biased position.
Point-of-care diagnostic systems and containers for same
The present disclosure relates to a medical diagnostic system. In various embodiments, the system includes a housing, a first receptacle in the housing for receiving a reagent container, a second receptacle in the housing for receiving a working fluid and waste container, where the second receptacle is larger than the first receptacle, two reagent access needles positioned and fixed within the first receptacle with each of the two reagent access needles being substantially horizontal to horizontally access the reagent container, and a working fluid access needle and a waste access needle positioned and fixed within the second receptacle with the working fluid access needle and the waste access needle being substantially horizontal to horizontally access the working fluid and waste container.
SEALING SYSTEM FOR CONTAINER COMPRISING A MATERIAL
A sealing system for container comprising material and a method using the system The present invention provides a sealing system for sealing a container comprising material, wherein the system comprises at least a first part which is a cap for sealing a container comprising a seal; and a second part which is a coupling member that is mounted to a dispenser unit, wherein the coupling of both parts with each other is configured that they can be twisted against each other while preventing axial movement of first and second part.
IN VITRO DIAGNOSTIC APPARATUS
The present invention relates to an automatic in vitro diagnostic apparatus capable of automatically performing a series of examination processes including a pretreatment process for specific components included in a biological sample such as blood and urine. The apparatus of the present invention comprises a base frame 104; a cuvette tray 110 movable back and forth on the base frame 104, for mounting cuvette holders 10 accommodating a plurality of cuvettes arranged thereon alongside each other; a tube tray 120 movable back and forth on the base frame, for mounting tube holders 20 accommodating a plurality of sample tubes containing samples thereon; and a sampling operation unit 500 movable left and right on the base frame 104, for mixing a sample contained in the sample tube with a reagent, and dropping the mixed solution onto an analysis strip provided in the cuvette.
AUTOMATED PURGE SYSTEM BY GAS INJECTION
The present invention addresses to an automated gas injection system in vials with rubber septa, for simultaneous injection of gas in 24 or more positions, with injection pressure control and/or overpressure detection, applied to mass spectrometry analyses and/or gas chromatography. The present invention can be used, for example, in isotopic analyses of geological materials in equipment with carbonate extraction units, in the cleaning and decontamination of tubes to be used in isotopic or chromatographic analyses, and in the removal of contaminants from steam drag or by continuous flow, or coming from the free space of vials or tubes in the analyses of organic and inorganic materials.
The application of this invention allows reducing the current times of routine purge (flush) of at very least 3 minutes for every 2 positions (72 positions in total and final time of 108 minutes, in a batch of samples) to a total of 96 positions in 3 minutes, with a reduction of 12 times or more in the flush time, which implies greater analytical capacity to the laboratory, lower external costs of sending samples, less time to obtain results, with technology that is easy to implement in universities and research centers in general, in addition to increasing the lifespan of rubber septa.
