Bubble trap with fluid guide

A bubble trap device comprising:

• a housing including an inner wall region defining a chamber to enclose a fluid;
• a fluid guide that includes a first surface region and a second surface region that face in opposite directions from one another and that includes a perimeter region;
• wherein the fluid guide is arranged within the chamber to separate the chamber into a first chamber region and a second chamber region with the first surface region facing the first chamber region and the second surface region facing the second chamber region and with the perimeter region spaced apart from the inner wall region;
• a first fluid conduit located between the first and second surface regions and extending between a first opening in the inner wall region and a first surface opening located in the first surface region;
• a second fluid conduit located between the first and second surface regions and extending between a second housing opening in the inner wall region and a second surface opening located in the second surface region;
• and
• one or more third fluid conduits located at one or more locations of the perimeter region to allow flow of fluid between the first chamber region and the second chamber region for substantially all orientations of the bubble trap device relative to a reverse gravitational direction, for fluid that flows into one or the other of the first chamber region or the second chamber region through a corresponding one or the other of the first surface opening or the second surface opening and that flows along a corresponding one or the other of the first surface region or the second surface region in the reverse gravitational direction.
