AI Technical Summary

Technical Problem

Existing devices for collecting bodily fluids are prone to contamination from skin commensal microorganisms and other external contaminants, leading to inaccurate diagnostic results, and often require user intervention or insufficient pressure to operate effectively in clinical settings.

Method used

A fluid control device with a housing, actuator, and flow controller that uses negative pressure to isolate an initial volume of bodily fluid, separating contaminants within an isolation chamber, allowing subsequent fluid to flow into a collection device.

Benefits of technology

Ensures collection of uncontaminated bodily fluid samples by isolating initial contaminants, facilitating accurate diagnostic testing and reducing user intervention, suitable for various clinical settings.

Abstract

To acquire samples of bodily fluids with reduced contamination.SOLUTION: A device (100) for procuring bodily fluid samples with reduced contamination includes a housing (110) having a sequestration chamber (130), an inlet (113) and an outlet (114). A flow controller (140) defines a portion of the sequestration chamber (130) and, in response to suction force exerted by a fluid collection device (180) fluidically coupled to the outlet (114), can transition 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 (130). An actuator (150) is coupled to the housing (110) and is in fluid communication with the inlet (113) and the sequestration chamber (130) in a first configuration, and transitions to a second configuration to sequester the sequestration chamber (130) from the inlet (113), and allow a subsequent volume of bodily fluid to flow from the inlet (113) to the outlet (114).SELECTED DRAWING: Figure 1
