Sample collection and processing device
A device for separating and concentrating target particles or molecules from a fibrinogen containing sample of liquid comprises a container (1) for collecting the sample and a closure (2). The container (1) comprises a first end and a second end and at least one interior wall defining a reservoir portion (5) for receiving the sample. The reservoir portion (5) comprises at least one anchor element (4) to locally catch a polymerized fibrin pellet formed upon the addition of the sample into the container. The separation and concentration process is operated by trapping the target particles or molecules into the so-formed polymerized fibrin pellet that are captured on the anchor element (4).
TEST TUBE HOLDING ASSEMBLY
A test tube holding assembly or test tube rack includes at least two test tube holders, where each test tube holder in turn defines a central longitudinal axis, two storage zones, and includes a connecting member. The connecting members permit coupling of the two test tube holders and rotation of the two coupled test tube holders about an axis parallel to the longitudinal axis of at least one of the test tube holders. The test tube holders are also positionable in multiple orientations, where each orientation at least partially determines which of the two storage zones are available to receive a test tube therein.
CUPPING DEVICE AND BLOOD ANALYSIS APPARATUS USING THE SAME
Provided are a cupping device and a blood analysis apparatus using the same. The cupping device includes a cupping cup having a first opening defined in a lower portion thereof, at least one blood collecting container disposed adjacent to an outer surface of the cupping cup and having an accommodation space configured to accommodate blood therein, and a connecting pipe disposed between the cupping cup and the blood collecting container to connect an inner space of the cupping cup to the accommodation space of the blood collecting container.
Capture, disruption, and extraction apparatus and method
A cell capture, disruption, and extraction method includes a introducing a plurality of abrasives in a disruption chamber, which can include diamond powder, variably and multi dimensionally disbursed therein, and a pestle positioned in the disruption chamber. The method includes agitating the abrasives by moving the disruption chamber and/or pestle, agitation of the abrasives tearing cell structure in the solution to access its contents. A binding column or size exclusion column can be positioned downstream of the disruption chamber. Cell solution can first be introduced in the disruption chamber, the abrasives capturing the cells and allowing therethrough and purging the waste content, then breaking the cell content. The lysate can then bind to an extraction matrix downstream of the disruption chamber or it can be mixed in with the abrasives.
Kits for stabilizing analytes in urine samples at room temperature
Disclosed here are kits comprising pre-packed stabilizing solutions for stabilizing combinations of biomarkers at room temperature. Such kits can be better adapted for sample collection at a subject's dwelling, thus easing the burdensome requirement of sample collection.
DEVICES AND METHODS FOR SYRINGE-BASED FLUID TRANSFER FOR BODILY-FLUID SAMPLING
An apparatus includes a housing, defining an inner volume, and an actuator mechanism movably disposed therein. The actuator mechanism is configured to be transitioned from a first configuration to a second configuration to define a pre-sample reservoir fluidically couplable to receive a pre-sample volume of bodily-fluid via an inlet port of the housing. The actuator mechanism is movable from a first position to a second position within the housing after the pre-sample reservoir receives the pre-sample volume such that the housing and the actuator mechanism collectively define a sample reservoir to receive a sample volume of bodily-fluid via the inlet port. The outlet port is in fluid communication with the sample reservoir and is configured to be fluidically coupled to an external fluid reservoir after the sample volume is disposed in the sample reservoir to transfer at least a portion of the sample volume into the external fluid reservoir.
LUCIFERIN-CONTAINING SUBSTRATE AND MONITORING DEVICE INCLUDING THE SUBSTRATE
Luciferin-containing substrates are provided including a substrate and luciferin dried on the substrate. The luciferin-containing substrate is free of a detectable amount of reactive luciferase. The substrate is optionally a nonwoven substrate. Monitoring devices are also provided. The monitoring devices include a test element having a test portion, a detection reagent comprising luciferase, a luciferin-containing substrate, and a container having a first end with an opening and a second end opposite the first end. The container is configured to receive the test portion and configured to be operationally coupled to an analytical instrument. The detection reagent and the luciferin each are capable of participating in one or more chemical reaction that results in the formation of a detectable product.
APPARATUS AND METHOD FOR CELL, SPORE, OR VIRUS CAPTURE AND DISRUPTION
Embodiments disclose an apparatus and methods for biological sample processing enabling isolation and enrichment of microbial or pathogenic constituents from the sample. A vessel for sample containment and extraction is further disclosed for engagement with a transducer capable of efficient sample disruption and lysis. Together these components provide a convenient and inexpensive solution for rapid sample preparation compatible with downstream analysis techniques.
APPARATUS AND METHOD FOR ISOLATING TARGET CELLS FROM A FLUID SAMPLE
Systems, methods, and apparatus are disclosed for recovering one or more target cells from a fluid sample. A first chamber aligned with a first surface of a removable filter receives the fluid sample. The removable filter defines a plurality of pores configured to retain the one or more target cells on the first surface and/or in the plurality of pores, each pore of the plurality of pores having a first diameter smaller than a diameter of the one or more target cells in the first surface and a second diameter greater than the first diameter in a second surface of the removable filter. A second chamber comprises a hydrophilic microporous wick structure configured to contact the second surface of the removable filter and capillarize any non-target cells and fluid from the fluid sample, drawing them into the second chamber.
FLUID HANDLING SYSTEMS FOR APPLICATION OF FLUID SHEAR STRESS TO A FLUID SAMPLE
A fluid handling system for applying a plurality of pulses of fluid shear stress to a fluid sample may comprise a first sample chamber; a second sample chamber; a plurality of conduits mounted between and in fluid communication with the first sample chamber and the second sample chamber; and a force delivery system mounted to the first sample chamber and configured to apply a force sufficient to push the fluid sample from the first sample chamber through each of the conduits at a substantially constant flow rate to the second sample chamber. The plurality of conduits may be arranged in series and separated by additional sample chambers or arranged such that the conduits are substantially parallel to one another. The force delivery system may be a gas delivery system or a linear drive assembly.
