Abstract: Biological sample processing system assemblies include a swab chamber assembly configured to enhance transfer of a biological sample on a swab head to a resulting biological sample solution for subsequent processing. A swab chamber assembly includes a fluid channel and an elongated swab chamber having a proximal portion and a distal portion. The swab chamber is configured to accommodate insertion of a swab head of a swab into the swab chamber. The distal portion of the swab chamber slopes downwardly from a distal end of the proximal portion of the swab chamber so that lysis buffer solution transferred into the swab chamber accumulates within the distal portion of the swab chamber.

Abstract: Diagnostic testing systems and related methods employ actuation pressure-based control during fluid transfer within a test cartridge. A method of operating a cartridge to process a biological sample includes coupling an actuation port of the cartridge with a pump assembly of a portable analyzer. A transfer operation of the pump assembly induces airflow through the actuation port so as to displace an aliquot of the sample solution along a fluid channel. A control unit monitors a pressure signal indicative of a pressure of air displaced by the pump assembly. The transfer operation is stopped in response to a change in the pressure signal indicative of contact of the aliquot of the sample solution with a hydrophobic staging vent.

Abstract: Single use cartridges for testing biological samples are provided that include multiple processing channels. A single use cartridge includes an aliquot staging well, a first amplification well, a second amplification well, an actuation port, and a fluid channel control valve assembly. The fluid channel control valve assembly is reconfigurable between a first fluid channel configuration and a second fluid channel configuration.

Abstract: A rechargeable battery pack can provide power to a device that also accepts at least one standard non-rechargeable battery. The rechargeable battery pack may include a housing for housing at least one battery cell and recharging circuitry. The at least one battery cell and the recharging circuitry can be housed substantially within the housing. The recharging circuitry can be coupled with the at least one battery cell. The recharging circuitry can be configured to charge the at least one battery cell when the battery pack is inserted into the device that also accepts at least one non-rechargeable battery. The rechargeable battery pack may further include a protection circuit coupled with the recharging circuitry.

Abstract: A ventilator system may include a ventilator and a graphic user interface (GUI) module. The GUI module may display a user interface for configuring a plurality of preset breath delivery therapies for providing ventilation assistance to a patient, and for selecting one of the plurality of preset breath delivery therapies to activate. Each preset breath delivery therapy may be defined by a set of ventilation parameter settings, and configuring each preset breath delivery therapy may include configuring at least one ventilation parameter setting. The ventilator may be configured to provide breathing assistance to the patient based at least on the set of ventilation parameter settings corresponding to the activated preset breath delivery therapy.

Abstract: A ventilator system includes a ventilator configured for ventilating a patient based on a plurality of ventilation parameters, and a multi-level graphic user interface (GUI) coupled to the ventilator. The multi-level GUI may be configured to display a view menu allowing a user to select from multiple different views providing different levels of user access to the ventilation parameters. The multiple different views may include a first view and a second view. The first view may display values for a first set of ventilation parameters, and user access for adjusting the setting for at least one of the first set of the ventilation parameters. The second view may display values for a second set of the ventilation parameters, and access for adjusting the settings for at least one of the second set of the ventilation parameters. The second set of ventilation parameters may be larger than the first set of ventilation parameters.
