  • Publication number: 20240248111
    Abstract: A diagnostic test device to perform a test on a biological or environmental sample is provided. In one aspect, the diagnostic test device includes a sample preparation reservoir; a dispensing mechanism that includes a sealing member and a piercing member; and at least one diagnostic test reservoir separated from the sample preparation reservoir by a seal. A predetermined volume of fluid is defined between the sealing member, the piercing member, sides of at least one chamber defined by the sample preparation reservoir, and the seal when the sealing member engages the sides of the at least one chamber. The piercing member disrupts the at least one seal to dispense the predetermined volume of fluid to the at least one diagnostic test reservoir. The sealing member is configured to directly contact the sides of the at least one chamber as the seal is disrupted.

  • Publication number: 20240210435
    Abstract: Disclosed herein include methods, compositions, and kits suitable for use in sample testing. The sample testing systems can comprise a cartridge body to receive a sample, at least one reaction chamber coupled to the cartridge body, and at least one seal between the cartridge body and the at least one reaction chamber. The sample testing system can comprise a sample dispensing mechanism operable to disrupt the at least one seal to dispense a predetermined sub-volume of sample fluid from the cartridge body into the at least one reaction chamber. The sample dispensing mechanism can comprise a dispense rod comprising at least one piercing tip that disrupts the at least one seal by forming at least one opening therein. The piercing tips can comprise a geometry configured to generate a large opening in the at least one seal.

  • Publication number: 20230172542
    Abstract: Disclosed herein is a system, apparatus and method directed to patient temperature control. The system can include a control module configured to provide fluid that is heated or cooled, a heating and cooling system configured to couple with the control module and receive the fluid, and a temperature sensor coupled to the control module, the temperature sensor configured to measure a body temperature of a patient and provide signals to the control module that indicate the body temperature. The system can include a neurostimulation device coupled to the control module to provide neurostimulation to the patient. The control module can include logic, stored on non-transitory, computer-readable medium that, when executed by one or more processors, causes performance of operations including generation and transmission of first instructions to the neurostimulation device causing initiation of a first neurostimulation procedure.

  • Patent number: 11344851
    Abstract: A biological fluid separation device adapted to receive a biological fluid sample having a first portion and a second portion is disclosed. The device includes a housing having a first chamber having a first chamber inlet for receiving the biological fluid sample therein and a first chamber outlet. The housing has a second chamber having a second chamber inlet and a second chamber outlet, and a separation member separating at least a portion of the first chamber outlet and the second chamber. The separation member is adapted to restrain the first portion of the biological fluid sample within the first chamber and to allow at least a portion of the second portion of the biological fluid sample to pass into the second chamber. An actuator, such as a vacuum source, draws the biological fluid sample into the first chamber and the second portion into the second chamber.

  • Patent number: 10064574
    Abstract: A flow regulator for a blood collection assembly includes a housing having an inlet and an outlet, which defines an interior space between the inlet and the outlet. A membrane having a first surface and a second surface is disposed at least partially within the interior space. The membrane has a first position where a flow path between the inlet and the outlet is substantially open, and a second position where the flow path between the inlet and the outlet is at least partially restricted. The membrane is configured to move between the first and second positions in response to a pressure differential acting on the membrane.
