Patent

CA 2754719

A device and method for providing portable biological testing capabilities free from biological contamination from an environment outside the device are provided. The device includes a portable housing. The device farther includes a volume surrounded by the housing and sealed against passage of biological materials between the volume and the environment outside the device. The device further includes a culture medium within the volume. The device further includes one or more ports configured to provide access to the volume while avoiding biological contamination of the volume. The device further includes a valve in fluidic communication with the volume and the environment. The valve has an open state in which the valve allows gas to flow from within the volume to the environment outside the device and a closed state in which the valve inhibits gas from flowing between the volume and the environment. The valve switches from the closed state to the open state in response to a pressure within the volume larger than a pressure of the environment outside the device.
