Publication number: 20240138734Abstract: A fluid control device includes an inlet configured to be placed directly or indirectly in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. The fluid control device has a first state in which a negative pressure differential produced from an external source such as the fluid collection device is applied to the fluid control device to draw an initial volume of bodily fluid from the bodily fluid source, through the inlet, and into a sequestration portion of the fluid control device. The fluid control device has a second state in which (1) the sequestration portion sequesters the initial volume, and (2) the negative pressure differential draws a subsequent volume of bodily fluid, being substantially free of contaminants, from the bodily fluid source, through the fluid control device, and into the fluid collection device.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Applicant: Magnolia Medical Technologies, Inc.Inventors: Gregory J.

Publication number: 20240065590Abstract: An apparatus for procuring bodily fluid samples with reduced contamination includes a housing having a sequestration chamber, an inlet, and an outlet. A flow controller defines a portion of the sequestration chamber and can transition—in response to a suction force exerted by a fluid collection device fluidically coupled to the outlet—from a first state in which the sequestration chamber has a first volume to a second state in which the sequestration chamber has a second volume greater than the first volume, to draw an initial volume of bodily fluid into the sequestration chamber. An actuator is coupled to the housing and is in fluid communication with the inlet and the sequestration chamber in a first configuration, and is transitioned to a second configuration to sequester the sequestration chamber from the inlet, and allow a subsequent volume of bodily fluid to flow from the inlet to the outlet.Type: ApplicationFiled: September 6, 2023Publication date: February 29, 2024Applicant: Magnolia Medical Technologies, Inc.Inventors: Gregory J.

Publication number: 20220151525Abstract: An apparatus includes an inlet configured to be placed in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. A sequestration portion can be configured to receive an initial volume of bodily fluid. A flow controller disposed in the sequestration portion can be configured to transition from a first state to a second state in response to contact with the initial volume of bodily fluid. As the flow controller transitions, a negative pressure differential can be defined that is operable to draw the initial volume of bodily fluid into the sequestration portion. When the flow controller is in the second state, the negative pressure differential can be substantially equalized such that (1) the sequestration portion sequesters the initial volume and (2) a subsequent volume of bodily fluid can be transferred from the inlet to the outlet.Type: ApplicationFiled: August 16, 2021Publication date: May 19, 2022Applicant: Magnolia Medical Technologies, Inc.Inventors: Gregory J.
