<p>A fluid transfer and mixing collection assembly includes a base and a test media, an inlet check valve, and an outlet check valve carried by the base. A bladder containing a fluid and a flexible member are carried by the base between the check valves and are separated by a membrane. The flexible member is depressable to cause a pointed member extending from the flexible member to rupture the membrane, releasable to draw a sample fluid into an interior of the flexible member through the inlet check valve to mix with the fluid from the bladder, and depressable again to pump the mixed fluids out of the interior of the flexible member through the outlet check valve and be transferred to the test media.</p> |
