  • Publication number: 20220111385
    Abstract: Blood sample collection and processing system (1) using a tube (102) and a holder (104) is described herein. The tube (102) includes a plasma separation system (114) for converting a whole blood sample into a plasma sample without using centrifugation. The plasma separation system (114) may comprise a microfluidic separation system such as a lateral cavity acoustic transducer system (113). The tube (102) is thereafter placed in the holder (104) for analysis regarding the plasma. The results of the analysis may be displayed to the user via a display screen (134) or an indicator of a different kind, to allow the user to determine whether the sample is sufficient with regards to volume, and/or quality for further use. Inasmuch as the analysis system (132) performs a rapid analysis of the plasma sample, the patient is still present and if the sample is insufficient, the healthcare provider can take another whole blood sample, counsel the client regarding the blood sample, or examine the patient further.

  • Publication number: 20210015414
    Abstract: Blood sample collection and processing system (1) using a tube (102) and a holder (104) is described herein. The tube (102) includes a plasma separation system (114) for converting a whole blood sample (129) into a plasma sample without using centrifugation. The plasma separation system (114) may comprise a filtration system such as a hollow fiber element (115). The tube (102) is thereafter placed in the holder (104) for analysis regarding the plasma. The results of the analysis may be displayed to the user via a display screen (134) to allow the user to determine whether the sample is sufficient for further use. Inasmuch as the analysis system (132) performs a rapid analysis of the plasma sample, the patient may still be present or in close proximity and if the sample is insufficient, the healthcare provider can take another whole blood sample (129), counsel the client regarding the blood sample (129), or examine the patient further.

  • Publication number: 20150217291
    Abstract: Systems and methods for processing and analyzing samples are disclosed. The system may process samples, such as biological fluids, using assay cartridges which can be processed at different processing locations. In some cases, the system can be used for PCR processing. The different processing locations may include a preparation location where samples can be prepared and an analysis location where samples can be analyzed. To assist with the preparation of samples, the system may also include a number of processing stations which may include processing lanes. During the analysis of samples, in some cases, thermal cycler modules and an appropriate optical detection system can be used to detect the presence or absence of certain nucleic acid sequences in the samples. The system can be used to accurately and rapidly process samples.

  • Patent number: 7518727
    Abstract: A system for detecting electromagnetic radiation from samples comprising: a plurality of sample volumes, each of said sample volumes confined within a portion of a capillary column; a plurality of electromagnetic radiation sources; a mirror for receiving electromagnetic radiation from the electromagnetic radiation sources and for reflecting the electromagnetic radiation to the sample volumes; a scanner attached to the mirror; a parabolic reflector for collecting sample electromagnetic radiation from the sample volumes, the sample electromagnetic radiation being generated as a result of interaction of the reflected electromagnetic radiation with the sample volumes; a plurality of filters for filtering the sample electromagnetic radiation; and a plurality of detectors for detecting sample electromagnetic radiation from the sample volumes, each of the detectors being configured to receive sample electromagnetic radiation that has passed through a corresponding one of the plurality of filters and generate a signa
