GENOME EXTRACTION DEVICE INCLUDING SAFETY CLIP COMBINED WITH INNER CHAMBER

Provided is a genome extraction device including a safety clip combined with an inner chamber, more particularly a genome extraction device to which the above-described dual chamber structure is applied so that the genome extraction device can be stored stably for a long time without the risk of reagent leakage and an inner chamber is moved up and down by way of vibration generated during a production and distribution process of a product so that a sealing member for sealing upper openings and lower openings of the inner chamber can be prevented from being perforated.

System and method for GMR-based detection of biomarkers

A system for detecting analytes in a test sample, and a method for processing the same, is provided. The system includes a cartridge reader unit that has a control unit and a pneumatic system, and a cartridge assembly that prepares the samples with mixing material(s) through communication channels. The assembly has a memory chip with parameters for preparing the sample and at least one sensor (GMR sensor) for detecting analytes in the sample. The assembly is pneumatically and electronically mated with the reader unit via a pneumatic interface and an electronic interface such that the parameters may be implemented via the control unit. The pneumatic system is contained within the unit and has pump(s) and valve(s) for selectively applying fluid pressure to the pneumatic interface of the assembly, and thus through the communication channels, to move the sample and mixing material(s) through and to sensor. The control unit activates the pneumatic system to prepare the sample and provide it to the sensor for detecting analytes, and also processes measurements from the sensor to generate test results.

Testing for particulates

A method is provided for testing for presence of a particulate selected from the group consisting of: a microorganism, a fungus, a bacteria, a spore, a virus, a mite, a biological cell, a biological antigen, a protein, a protein antigen, and a carbohydrate antigen. The method includes (a) collecting, in a tube (22), fluid that potentially contains the particulate, (b) using a plunger (24) to push the fluid through a filter (26) disposed at a distal portion of the tube or at a distal end of the plunger, and subsequently, (c) while the filter is inside the tube, ascertaining if any of the particulate was trapped by the filter by applying a particulate-presence-testing-facilitation solution to the filter. Other embodiments are also described.

Acoustic based cell separation

Apparatus and method for separating whole cells from a mixture, e.g., including liquid, other cell types, nucleic acid material, or other components. Focused acoustic energy may be used to move whole cells in a chamber so that the cells exit the chamber via a first outlet rather than a second outlet. A filter may, or need not, be used to assist in separation.

Extraction system for testing microbial contamination of tissue products

An extraction system for testing microbial contamination includes a biocompatible outer vessel that has a side wall and a biocompatible suspension system that is positionable within an interior of the biocompatible outer vessel. The biocompatible suspension system includes a horizontal member on which a sample may be supported and a securement mechanism that is engagable with the side wall of the biocompatible outer vessel to maintain the suspension system at a desired position within the biocompatible outer vessel.

ENRICHER, ENRICHEMENT SYSTEM, SAMPLE MANUFACTURING SYSTEM, AND SAMPLE DETECTION SYSTEM
20230038927 · 2023-02-09 ·

An enricher, an enrichment system, a sample manufacturing system, and a sample detection system. The enricher comprises an enrichment housing, which encloses to form an enrichment cavity used for accommodating a suction liquid; a suction connection part, which is used to place a suction mechanism in communication with the enrichment cavity so that the enrichment cavity forms negative pressure under a vacuumization mechanism; and a blocking member, which is disposed on the enrichment housing; when the enrichment cavity forms negative pressure, a sample can, by means of the blocking member, form a suction liquid that enters the enrichment cavity, and a retentate remains on the blocking member.

UNIVERSAL ASSAY CARTRIDGE AND METHODS OF USE

Sample cartridge, valve assembly and processing methods for providing mechanical lysis, chemical lysis or both for a given fluid sample are provided herein. Such systems can include a sample processing cartridge having a valve assembly configured for transport of the processing of fluid sample within the sample cartridge. The valve assembly can include a valve body and cap that secure a filter therebetween and facilitate inflow of mechanical or chemical lysing agents as needed for a fluid sample. Assay workflows for performing both mechanical and chemical lysis of a fluid sample within the same workflow of a single universal sample cartridge are also provided.

Cell isolation instrument

Provided is a cell isolation instrument capable of smoothly performing a plurality of steps associated with isolation of cells, including gripping of a biological tissue, transferring of the biological tissue, and isolating of the biological tissue. A container has an opening. A sealing member seals the opening. A pair of pinching parts is connected to the sealing member, and the pair of pinching parts opens or closes by being pressed.

Assembly of a Containment Means with an Aseptic Working Chamber

The subject matter is the assembly of a containment means with an aseptic working chamber and associated decontamination arrangement. The working chamber is delimited at the bottom by a base, and above the working chamber is a circulating air zone, in which a circulating air filter with a circulating air fan is arranged. The circulating air zone and the working chamber are delimited towards the outside by a housing. At least a first returning air channel leads from the working chamber into the circulating air zone. A returning air filter is fluidically connected to the returning air channel, specifically is arranged facing the circulating air zone. The returning air filter can be arranged at the opening of the returning air channel into the circulating air zone or arranged in the circulating air channel, set back from the opening. The returning air filter and the circulating air filter are in the form of a plate filter or an exchangeable filter cartridge or a replaceable filter insert. A single returning air filter or a series of interacting returning air filters and a single circulating air filter or a series of interacting circulating air filters can be installed. Containment means in which larger volumes of air are to be processed also have a second returning air channel at or in which a returning air filter is also installed.

System and method for determining an immune activation state

A method and/or system can include processing a blood sample of a patient by degrading red blood cells of the blood sample using a lysing solution, quenching the degradation of the red blood cells after a threshold lysing time, centrifuging and aspirating the quenched solution to remove degraded red blood cell debris and concentrate white blood cells of the blood sample, and suspending the concentrated white blood cells in a buffer solution; within a threshold transfer time, deforming white blood cells, of the suspended white blood cells, within a microfluidic chip; and determining a probability that the patient is in an immune activation state based on images of the white blood cells acquired while deforming the white blood cells.
